In this paper, we study the time evolution of three-states spin-1 non-Hermitian systems. The state vector of the wave function for Schrödinger equation is obtained analytically by using the Cayley–Hamilton theorem. We note that the behavior of the non-Hermitian three-states system corresponds to the Hermitian three-state system. Furthermore, the fluctuation between three-state spin-1 is periodically oscillating when the eigenvalues of the non-Hermitian system are real. Moreover, if the eigenvalues are imaginary, we explore that from our analysis and analytical solution that the probabilities' amplitudes always grow with time for all physical parameters in the three-state, i.e. including the -symmetry non-Hermitian system. It means that the Schrödinger equation becomes the growth exponential. [ABSTRACT FROM AUTHOR]

In this paper, we study quantum entanglement and non-classical statistical aspects for a model describing two three-level Λ atoms interacting with a single-mode cavity field. The Hamiltonian describes multi-photon processes and includes the Kerr-like medium in the resonance case. The constants of motion are obtained from the Hamiltonian operators under the rotating wave approximation. The exact solution of the wave function for the whole system is obtained under the special initial conditions when the atom is in the ground state and the field in the coherent states. The results are used to perform some studies on the temporal evolution of collapse revival, normal squeezing function, photon antibunching and Q-function to measure the degree of entanglement between subsystems. Entanglement dynamics using von Neumann entropy and Shannon information is used to quantify the entanglement in the quantum subsystems. The numerical results show that the presence of these parameters plays an essential role in developing these aspects. The above optical schemes have many advantages and can be used in various experiments in quantum optics and information, such as trapped ions and quantum electrodynamics resonators.

Fe 3 O 4 nanoparticles were embedded within a glauconite‑calcium alginate (G/CA) matrix to create magnetic hybrid spheres (MNPs-G/CA), with the aim of purifying water from methylene blue (MB) at temperatures of 25, 40, and 50 °C. MNPs-G/CA adsorbent was characterized using numerous techniques, including elemental mapping, zeta potential, FTIR, FESEM, XRD, EDX, and TEM. The greatest amount of the removed MB was achieved under definite conditions of solution pH 8.0, MNPs-G/CA mass (25 mg), interaction time (2 h), and 200 mg/L of MB concentration. The MB uptake process kinetic followed a pseudo-second-order equation (R 2 > 0.99) at all tested temperatures. The equilibrium data were fitted to a statistical physics multilayer model in conjunction with the Langmuir and Freundlich equations. The steric n parameter reveals that MNPs-G/CA adsorbent possesses a mixed adsorption orientation (i.e., ranging from 0.69 to 0.93) across various temperatures. The amount of MNPs-G/CA active positions (the N M parameter) was progressively increased from 245 mg/g to 419 mg/g. The measured adsorption capacities (Q s at) ranged from 466.49 to 664.37 mg/g, and the removal of MB molecules was consistent with an endothermic interaction. The interface between the MNPs-G/CA-MB was principally dictated by electrostatic attractions, as evidenced by the values of adsorption energies (∆ E), which varied from 16.75 to 21.52 kJ/mol. The regenerated MNPs-G/CA offered over 80 % of its adsorption strength after the fourth adsorption–desorption cycle. This study contributes to our understanding of the physicochemical parameters controlling the MB adsorption mechanism on multifunctional hybrid adsorbents, like the interface between glauconite, alginate, and MNPs.

Background: Mycobacterium bovis notoriously causes detrimental infections in bovines and humans. In this study, 1500 buffaloes and 2200 cattle were tested by single intradermal comparative cervical tuberculin test and compared with the detection rates of M. bovis isolation, real-time and simplex PCR, and flow Cytometry. Results: The tuberculin test is the reference test in Egypt, the positive rate was 54/3700 (1.5%) composed of 18/1500 (1.2%) buffaloes and 36/2200 (1.6%) cattle which were mandatorily slaughtered under the Egyptian legislation, after postmortem examination the non-visible-lesion proportion was 39/54 (72.2%) which surpassed the visible-lesion rate 15/54 (27.8%) with (p < 0.0001). The samples from each case were pooled into one sample representing the case, and the isolation rate of M. bovis was 25/54 (46.3%). Real-time PCR using atpE was positive for mycobacteria on the genus level in 18/18 (100%) and 5/5 (100%) of tissue samples and isolates, respectively; simplex PCR detected M. bovis in 44/54 (81.5%) and 25/25 (100%) of tissue samples and isolates, respectively. Flow Cytometry evaluation of the CD4+, CD8+, WC1+δγ, and CD2+ cell phenotypes showed increased counts in the tuberculin-positive cases compared with negative cases (p < 0.0001), and these phenotypes in the tuberculin-positive cases increased after antigen stimulation than in the negative cases (p < 0.0001). Detection rates of PCR techniques and flow Cytometry exceeded that of bacterial isolation (p < 0.0001) and exhibited a strong correlation. Conclusions: The skin test suffers from interference from non-tuberculous mycobacteria able to cause false-positive reactions in cattle and other species. Real-time PCR using atpE, conventional PCR targeting RDs, and flow Cytometry are rapid and accurate methods that correlate with the isolation and can be promising for detection and confirmation of infected live and slaughtered cases.

[Display omitted] • Magnetite product with nearly 85 % of Fe 2 O 3 was extracted from Sinai copper ore. • Magnetite/heated glauconite mixture was activated to form a magnetic geopolymer (GMG) for crystal violet adsorption. • The Freundlich and multilayer models fitted the CRV uptake at all temperatures. • CRV adsorption capacities of this new material ranged from 612 to 684 mg/g. • GMG displayed high adsorption capacity (nearly 74%) after the fourth adsorption–desorption cycle. Sinai copper ore with 9.48 % of Fe 2 O 3 was treated using a laboratory-scale mineral processing techniques that included size reduction (below 75 µm) and a wet low intensity drum-type magnetic separation. After this treatment method, the separated magnetite product containing about 85 % of Fe 2 O 3 was extracted. A mixture of heated glauconite (900 °C/2h) and the extracted magnetite was activated by sodium silicate (Na 2 SiO 3) to obtain a novel glauconite-based magnetic geopolymer (namely GMG). Several analytical techniques (i.e., XRD, XRF, FESEM, FTIR, EDX, TEM, elemental mapping, and zeta potential) were used in the characterization of GMG and its performance for crystal violet (CRV) remediation was studied. The equilibrium data at pH 8.0 and 25 – 50 °C were fitted to a statistical physics multilayer model and classical isotherm equations to understand the CRV adsorption mechanism. The theoretical calculations indicated that GMG can adsorb 1.12 to 1.39 of CRV molecules per functional group (n), suggesting the presence of a multi-interaction mechanism and vertical adsorption orientation on GMG surface. For this basic dye, the estimated saturation adsorption capacities (Q sat) ranged from 684 to 612 mg/g, and an exothermic binding interaction was associated with the removal of this dye molecule. The adsorption energies (Δ E) ranged between 15.05 and 36.74 kJ/mol, indicating that physical forces, such as electrostatic interactions and hydrogen bonds, governed the GMG-CRV interactions. After fourth adsorption–desorption cycles, the regenerated GMG showed 74 % of its adsorption capacities, which suggested the suitability of this adsorbent to be regenerated and reused multiple times in water treatment. Overall, the combination between the separated magnetite and glauconite was an effective approach for the remediation of effluents that contain dye molecules [ABSTRACT FROM AUTHOR]

In this paper, we present the interaction between a five-level Λ -configuration atom and a two-mode quantized field in the presence of the damping with the nonlinearity. According to the generalized nonlinear Jaynes–Cummings model (JCM) and the analytical solution of the Schrödinger equation, the general formula of the wave function for this system under special conditions, where the atom (the field) is initially prepared in the excited state (coherent state), has been found. Under some particular conditions, the five-level Λ -type atom can be reduced to the three-level Ξ -type atom. Some physical aspects of the atom-field entangled state showing the entanglement degree, such as the field entropy. Moreover, we evaluate some of their non-classical statistical aspects such as atomic inversion. The effects of the physical parameters such as a Kerr medium, detuning parameter and the intensity-dependent coupling on the temporal behavior of the latter mentioned non-classical statistical aspects have been explored. We show that by choosing the evolved parameters in the interaction process, each of the above non-classical statistical features can be treated. We found that the parameters have an important influence on the properties of these phenomena. [ABSTRACT FROM AUTHOR]

Acne vulgaris is one of the most common chronic inflammatory skin disorder affecting millions of people worldwide. Vitamin D deficiency has a role in various inflammatory skin diseases as acne. This study aimed to investigate the serum level of 25 hydroxy vitamin D in acne patients and to assess the efficacy and safety of active vitamin D in management of acne. This study was conducted on 100 patients with acne and 100 healthy controls, then the 100 acne patients were randomized to either the study group that received 0.25ug alfacalcidol daily or the placebo group that received oral placebo during the 3 months study period. Serum levels of 25-hydroxy-vitamin D were significantly lower in acne patients than in healthy control and were inversely correlated to the severity of acne. After alfacalcidol administration, the study group showed significant higher level of 25(OH) D levels (p <.05) compared to placebo group. In addition, median serum level of IL6 and TNFα significantly decreased (p <.05) in the study group in comparison to placebo group and as compared to their baseline results. Acne patients are more commonly to have vitamin D deficiency as compared to healthy people and hence, alfacalcidol might have a beneficial role in the acne management with no reported side effects.

In this work, a CNT based TFET label free biosensor is investigated. A nanogap is introduced under the gate at the source side where the biomolecules are fed. The drain current of the TFET depends on the gate dielectric material. Thereby, sensing of the biomolecules is achieved by dielectric modulation. The sensitivity of the device is studied in terms of the ON-current and also in terms of the threshold voltage. The effect of the cavity length and dielectric constant of the gate insulator on the sensor sensitivity is investigated. Also, the CNT chirality index is adjusted for better sensitivity. The device performance for biosensing applications is analysed for different biomolecules with different dielectric constants. Moreover, the sensitivity of the sensor for both neutral and charged biomolecules is examined. A quantum 2D simulator, which is based on self-consistent solution of non-equilibrium Green's function and Poisson's equation, is utilized to study the device performance. A higher device sensitivity is achieved by using low-k gate oxides and CNTs with higher chirality index. In addition, sensitivity and selectivity increases for higher charge density biomolecules. The results, provided in this work, demonstrate the ability of CNT-TFETs to function as a free-label biosensor. [ABSTRACT FROM AUTHOR]

In this work, the effect of the source doping profile due to possible fabrication aspects has been investigated and discussed for both carbon nanotube tunneling field effect transistors (TFETs) and metal oxide semiconductor field effect transistors (MOSFETs). A quantum 2D simulator, which is based on self-consistent solution of non-equilibrium Green's function and Poisson's equation, is utilized. It has been found that the source doping gradient remarkably affects the drain current, especially in the case of TFET. This raises the need for fabrication precautions and design to retain higher ON-state current. Besides, the high frequency behavior of TFET and MOSFET structures is inspected in terms of cut-off frequency fT. It is found that the source doping profile has a more significant impact on TFETs than on MOSFETs. For better performance, source doping needs to be abrupt. However, with a small source-gate underlapping, degradations due to gradual doping can be reduced. It is also found that a TFET with source/drain low-k oxide spacer can achieve more immunity to these degradations than the single oxide structure. [ABSTRACT FROM AUTHOR]

[Display omitted] Naringenin, a natural dihydrochalcone flavonoid, exhibits diverse pharmacological properties. This study investigates the hypolipidemic effects of Nar-NPs on obese mice. The characteristics of Nar-NPs, including morphology, particle size, zeta potential, UV–vis, and FT-IR spectra, were examined. The anti-obesity properties of Nar-NPs were evaluated in obese rats, considering LD 50 , 1/20 LD 50 , and 1/50 LD 50 for treatment preparation. Results indicated that synthesized Nar-NPs were uniform, spherical, and well-dispersed, with a size of 130.06 ± 1.98 nm and with a zeta potential of −25.6 ± 0.8 mV. Nar-NPs exhibited enhancement in the cumulative release of naringenin (56.87 ± 2.45 %) as compared to pure naringenin suspension 87.83 ± 1.84 % in 24 h of the study. The LD 50 of Nar-NPs was determined as 412.5 mg/kg.b.w. HFD induced elevated glycemic, oxidative stress, and inflammatory biomarkers while reducing HDL-C, GSH, and superoxide dismutase (SOD) levels. Administration of Nar-NPs significantly mitigated body weight, glucose, insulin, leptin, TC, TG, SREBP1c, pAMPK, PPAR-α, as well as vanin-1, MCP-1, and iNOS mRNA gene expression. Histological investigations supported the biochemical and PCR findings. In a nutshell, the study suggests that the Nar-NPs could serve as a promising and viable pharmacological strategy for the treatment of obesity-related disorders. [ABSTRACT FROM AUTHOR]

Vitamin D is a regulatory factor for immunity and skin barrier functions. It is hypothesized to be linked to atopic dermatitis (AD) which is characterized by interaction between epidermal barrier dysfunction and dysregulation of skin immune functions. One hundred AD patients and one hundred and one normal controls were collected from outpatient clinic based on their clinical condition, both had measurement of 25-hydroxyvitamin D [25(OH)D]. We assessed the relationship between 25(OH)D deficiency and AD prevalence using adjusted Poisson regression model. Serum 25(OH)D levels were significantly lower in cases than controls (mean 35.1 versus 22.6 ng/mL, p <.001). The unadjusted prevalence ratios (PRs) (95% CI) for AD for comparing participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.11 (1.91, 5.06) and 4.77 (2.99, 7.60), respectively. The association did not materially change after adjusting for potential confounders. In the fully adjusted analysis stratified by gender, PRs for AD for comparing male participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.38 (1.21, 9.40) and 5.20 (1.91, 14.13), respectively, whereas in the female participants were 1.32 (0.96, 1.83) and 1.49 (1.04, 2.14), respectively (p-interaction <.001). In this case-control study in children, we found a statistically significant dose–response association between vitamin D deficiency and AD. We also observed a statistically significant effect modification of this association by gender. Further research is recommended to study this association longitudinally, and to examine whether treating vitamin D deficiency may potentially improve AD. Question: Can atopic dermatitis be associated with vitamin D deficiency? Finding: Serum 25(OH)D levels were significantly lower in cases with AD than in controls. Prevalence ratios for comparing male participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.38 (1.21, 9.40) and 5.20 (1.91, 14.13), respectively, whereas in the female participants were 1.32 (0.96, 1.83) and 1.49 (1.04, 2.14), respectively (p-interaction <.001). Meaning: vitamin D deficiency is associated with AD in children, effect modification of this association by gender was also observed. [ABSTRACT FROM AUTHOR]

Macrophages (Mϕs) play an essential role in maintaining body homeostasis. They perform dual functions produced by different subtypes. Mϕs not only fight against pathogens and foreign bodies such as bacteria or cancer cells but also participate in healing and repairing damaged tissue since they maintain both proinflammatory and anti-inflammatory effects sequentially. Tumors possess the ability to polarize Mϕs from proinflammatory M1 subtype to anti-inflammatory M2-like Mϕs called tumor-associated macrophages, which, in turn, help the tumors to acquire cancer hallmarks. Consequently, this polarization allows tumors to grow and spread. In this light, Mϕs have been a subject of intense study, and researchers have developed protocols to derive different Mϕs subtypes either as a new state-of-the-art therapeutic approach or to understand the cross-talk between cancer and Mϕs. In this review, we present the use of primary Mϕs in adoptive immunotherapy for cancer, illustrate the reciprocating interplay between cancer and Mϕs, and the resulting structural and functional change on both cell types. Furthermore, we summarize the recent cutting-edge approaches of using Mϕs in cancer immunotherapy. [ABSTRACT FROM AUTHOR]

Hepatitis C virus (HCV) infection is a major health problem all over the world including Egypt. Chronic HCV infection is usually accompanied by decrease of libido and erectile dysfunction. This study aimed to evaluate the efficacy of new oral direct acting antiviral (DAA) therapy on sexual function of male patients with HCV. This study was conducted on 200 male participants divided into two groups, first group included 100 male patients with HCV and the second group included 100 healthy age matched males as a control. Patients received DAA for three months and virological free status was confirmed by polymerase chain reaction. All participants were subjected to full history taking, general examination and local genital examination, assessment of sexual function by a validated Arabic version of the international index of erectile function‐5. Laboratory investigations included liver functions serum testosterone, free testosterone, sex hormone‐binding globulin and bioavailable testosterone. Results of this study showed that patients with HCV suffer from sexual dysfunction than controls that significantly improved after DAA therapy, and this is accompanied by increasing of bioavailable testosterone. It could be concluded that beside its effectiveness in treatment of HCV infection, DAA therapy can improve sexual function in male patients with HCV. [ABSTRACT FROM AUTHOR]

The Dzyaloshinsky–Moriya (DM) interaction contributes to some unusual and interesting magnetic properties in real materials, thus playing an important role in the degree of quantum entanglement in Heisenberg quantum spin models. In [C. S. Castro, O. S. Duarte, D. P. Pires, D. O. Soares-Pinto and M. S. Reis, Phys. Lett. A380, 1571 (2016)], it has been investigated about the non-locality and the thermal entanglement in a dipolar spin thermal system without DM interaction. In this work, we study the entanglement in the thermal state of inhomogeneous Heisenberg coupling under the presence of the DM interaction along the z -axis. More precisely, we analyze the effect of the DM interaction on non-locality phenomena and quantum entanglement as measured by negativity and Von Neumann entropy. We show that by comparing with [C. S. Castro, O. S. Duarte, D. P. Pires, D. O. Soares-Pinto and M. S. Reis, Phys. Lett. A380, 1571 (2016)], the local quantum states become more pronounced, when the DM interaction is taken into account. This fact is well confirmed by noting that Von Neumann entropy is destroyed in the presence of the DM interaction. It can be deduced that the Dzyaloshinsky–Moriya (DM) interaction makes the thermal states less correlated. [ABSTRACT FROM AUTHOR]

In this paper, we investigate the effects of gravitational field on the dynamical behaviour of nonlinear atom–field interaction. We consider a moving tripod-type four-level atom interacting with a single mode field in the presence of a classical homogeneous gravitational field. The analytical solution of the model is calculated by using the Schrödinger equation for a coherent electromagnetic field and when the atom is in its excited state. The influence of the detuning parameter and the classical homogeneous gravitational field on the temporal behaviour of atomic inversion, Mandel Q-parameters, purity of the atomic system and concurrence is studied. Our proposal has many advantages over the previous optical schemes and can be realised in several multiple experiments, such as quantum gravity. The results show that the gravity parameter has an important effect on the properties of these phenomena. Finally, conclusions and some features and comments are given. [ABSTRACT FROM AUTHOR]

Background: Acute coronary syndrome (ACS) necessitates immediate and efficient management, often using percutaneous coronary intervention (PCI) as a popular treatment method. The selection of the access site, whether it is transradial access (TRA) or transfemoral access (TFA), may have a substantial effect on clinical results. Objective: This study aimed to compare TRA and TFA in terms of PCI-related bleeding complications, access site complications, procedural duration, and hospital mortality in ACS patients undergoing PCI. Patients and Methods: A prospective, randomized, controlled trial was conducted on a total of 150 patients presenting with ACS indicated for PCI. They were randomized into two groups: 75 patients in the TRA group and 75 patients in the TFA group. Primary outcomes were bleeding complications and major adverse cardiac events (MACE). Secondary outcomes included cardiovascular death, stent thrombosis, and urgent revascularization. Results: Hematoma occurred significantly more in the TFA group (13.3%) compared to the TRA group (0%) (P = 0.001). The incidence of MACE was higher in the TFA group (13.3%) than in the TRA group (6.7%) but without statistical significance (P = 0.174). Multivariate logistic regression analysis revealed that femoral access was associated with a non-significant two-fold increased risk of MACE (OR = 2.181, 95% CI: 0.697-6.824, P = 0.18). Conclusion: TRA is associated with fewer hematoma complications and a trend toward lower MACE compared to TFA in ACS patients undergoing PCI. TRA may be preferred for reducing access site complications. [ABSTRACT FROM AUTHOR]

In this paper, we present a rigorous investigation of the quantum phase transitions (QPTs) for a model which describes the degenerate collective regime of a three-level V-configuration atoms Bose-Einstein condensate (BEC). We consider that the three-level atoms of a BEC coupled to an optical resonator (cavity) with high finesse in the presence of a diamagnetic term, i. e., a system of N-identical three-level atoms interacting with a one-mode quantized electromagnetic cavity field. Also, the different components of this system are labeled by the different phase factors. By using the Glauber's coherent states for the field, we calculate the free energy and study the finite-temperature phase transition for this model in the thermodynamic limit (N → ∞). Also, the potential energy surfaces constructed by taking the expectation value with respect to the direct product for a test state a direct product of coherent Heisenberg-Weyl HW(1)-states (for the electromagnetic field), and U(3) (for the atomic field, i. e., matter contribution) coherent states. Moreover, the scaled ground-state energy is obtained by taking the expectation value of an effective Hamiltonian in the framework of the mean-field approach. In the thermodynamic limit, the energy surface takes a simple form for a direct description of the phase transitions. The relation between the QPTs and the symmetry physics are established and the QPTs for this model are investigated numerically. The properties of both stability and the equilibrium are calculated using the catastrophe theory. We notice that the second-order phase transitions (superradiant (SR)) with multi-level systems might be achievable in a wide range of physical systems, especially those where it is possible to engineer the spec-tra and oscillator strengths.

In this paper, we study the interaction between the time-dependent field and a two-level atom with one mode electromagnetic field. We consider that the field of photons is assumed to be coupled with modulated coupling parameter which depends explicitly on time. It is shown that the considered model can be reduced to a well-known form of the time-dependent generalized Jaynes–Cummings model. Under special initial conditions, in which the atom and the field are prepared in the excited and the coherent states, respectively, the explicit time evolution of the wave function of the entire system is analytically obtained. Our proposal has many advantages over the previous optical schemes and can be realized in several multiple experiments, such as trapped ions and quantum electrodynamics cavity. The influence of the time-dependent field parameter on the collapses-revivals, the normal squeezing of the radiation, the anti-bunching of photons and the entanglement phenomena for the considered atomic system is examined. The linear entropy, the von Neumann entropy are used to quantify entanglement in the quantum systems. We noticed that these phenomena are affected by the existence of both the time-dependent coupling field and detuning parameters. [ABSTRACT FROM AUTHOR]

Appendiceal anomalies are extremely rare malformations that are usually found incidentally. Agenesis and duplication of the appendix has been well documented, however the reported cases of appendiceal hypoplasia are very limited, as only few cases have been reported so far. Here, we report a 31-year-old male who underwent appendicectomy after clinical presentation and diagnosis of appendicitis. The appendicular specimen showed all histomorphological features of appendiceal hypoplasia. Appendiceal hypoplasia is often missed and usually difficult to be diagnosed in the preoperative workup. The chief concern in this case is to focus on the classical histo-morphological features of appendiceal hypoplasia, especially in view of its clinical course. [ABSTRACT FROM AUTHOR]

Annular energy distribution, AED is a new concept deduced from radial dose, RDD that enables one to draw a map of energy-dose distribution around the ion's path at the nanometer scale better than the ordinary radial dose. The distribution of energy for different equal LET groups of ions of the same LET (keV/μm) were studied using this concept. Annular energy distributions, AEDs for 185 ions impeded in water medium were studied using Katz radial dose formula. AED was calculated using Butts-Katz and Tabata electron range-energy (R-E) relations and were compared. AED and shell annular energy distribution, SAED for those ions were mapping and confirming that energy distributions for ions of the same LET are not the same. AED growth with annular width r = 0.1 (n m) ⟶ R min (n m) showing a peak at the maximum annular energy width, r MAEW. Butts-Katz and Tabata show same annular energy distribution peaks of the same value, however, Tabata shows that energy is distributed over a wide range than Butts-Katz. Thus, Butts-Katz R-E relation is recommended and considered. AED for the studied 185 ions shows a peak at certain width called the maximum annular energy width, r MAEW. This r MAEW showed a monotonic increasing function with ion's β2. The total annular energy distribution, TAED for the different ions were determined and it shows a linear increasing function of the ion's (Z*/β)2. • Annular energy distribution is a new concept introduced. • Shell annular energy distribution is illustrated. • Katz R-E relation gives reasonable range over which energy is distributed. • Maximum annular energy width is ion's β2 dependence. • Total annular energy shows a monotonic increasing function with ion's parameters.

In order to scrutinize the impact of the decoration of Au upon the sensing performance of an YN nanotube (YNNT and X = B, Al, or Ga) in detecting phosgene oxime (PO), the density functionals M06-2X, τ-HCTHhyb, and B3LYP were utilized. The interaction of the pristine YNNT with PO was physical adsorption. The sensing response (SR) of approximately 8.0. Decoration of the Au metal into the surface of the YN led to an increase in the adsorption energy of PO from − 3.4 to − 18.2 (for boron nitride nanotube = BNNT), from − 3.8 to − 19.1 (for aluminum nitride nanotube = AlNNT), and − 4.3 to − 19.8 (for gallium nitride nanotube = GaNNT) kcal/mol, respectively. Also, there was a significant increase in the corresponding SR to 30.5, 61.5, and 102.5, and the sensitivity of metal decorated YNNT (metal@YNNT) increased. We found that Au-decorating increases the sensitivity of GaNNT toward PO compare to AlNNT and BNNT. Also, the recovery time for PO to be desorbed from the Au@GaNNT surface was found to be short (26.8 s). Thus, Au@GaNNT is suggested as a promising chemical sensor for PO detection.

We study the interaction between a single mode electromagnetic field and a three-level -type atom in the presence of a classical homogenous gravitational field when the atom is prepared initially in the momentum eigenstate. The model includes the detuning parameters and the classical homogenous gravitational field. The wave function is calculated by using the Schrödinger equation for a coherent electromagnetic field and an atom is in its excited state. The influence of the detuning parameter and the classical homogenous gravitational field on the temporal behavior of the mean photon number, the normalized second-order correlation function and the normal squeezing is analyzed. The results show that the presence of these parameters has an important effect on these phenomena. The conclusion is reached and some features are given. [ABSTRACT FROM AUTHOR]

Objective: In this study we assess the value of left atrial dyssynchrony time measured by tissue Doppler imaging (TDI) to predict recurrences after pulmonary vein isolation (PVI) in patients with paroxysmal and persistent atrial fibrillation (AF). Methods: One hundred sixty patients (57±7.5 years, 122 males) with symptomatic drug-refractory paroxysmal and persistent AF, undergoing PVI were enrolled in our study. PA peak time by tissue Doppler imaging (PApeak-TDI) is defined as the time measured from the start of P wave in lead II to the peak of A wave on the tissue Doppler tracing. Left atrial dyssynchrony was measured by subtracting the PApeak-TDI time measured at the mid-inter atrial septum from the PA peak-TDI time measured at the left atrial midlateral free wall, (LA dyssynchrony=PApeak TDI lateral-PApeak TDI septal). Results: During a mean follow-up of 12±3 months, recurrences occurred in 50 out of 160 patients. Patients with recurrence of atrial fibrillation had larger left atrial dyssynchrony time (26.5±2.4 ms vs. 23.5±2.3 ms, p<0.001). Left atrial dyssynchrony time of 25 ms has the best combined sensitivity and specificity (74% and 63% respectively) along with positive predictive value 53% and negative predictive value 85.5%. LA dyssynchrony time ≥25 ms was found to discriminate patients prone to AF recurrences over time. Multivariate regression analysis showed that left atrial dyssynchrony time (HR per ms: 1.69, p<0.001) was identified as independent predictor of AF recurrence. Conclusion: Left atrial dyssynchrony time is good clinical predictor of recurrence of AF after PVI in patients with paroxysmal and persistent AF. [ABSTRACT FROM AUTHOR]

In this study, we present the homotopy analysis transform method for finding solution of fractional diffusion-type equations. We can attain these equations by substituting a first-order time derivative by a fractional-order derivative in regular diffusion equation. We add some examples in order to illustrate the usefulness and efficiency of our novel proposed technique for fractional diffusion equations. [ABSTRACT FROM AUTHOR]

Blunt diaphragmatic rupture is an uncommon injury and even less common is the bilateral form. This entity poses diagnostic and therapeutic challenges to the treating team. Despite the advances in diagnostic modalities, it remains a difficult diagnosis leading to missed or late presentations with increased risk of morbidity and mortality. We report a case of a 12-year-old girl who sustained a blunt abdominal trauma and found to have left hemidiaphragmatic rupture for which she underwent laparotomy and repair. Postoperatively, persistent elevation of the right hemidaiphragm was noticed, and right-side rupture was suspected and confirmed by collar sign on repeated computed tomography scan. The second repair was done successfully through a right posteriolateral thoracotomy. She improved dramatically and was discharged in an optimal state to be followed in the surgical outpatient department. [ABSTRACT FROM AUTHOR]

The results show that Wood Chips of Acacia Nilotica trees available in Sudan lands can be successfully used in the gasification process and, on the same basis, as a bio-renewable energy resource. Simulation models were used to characterize the air gasification process integrated with a Regenerative Gas Turbine Unit. The results revealed that at a moisture content of 12%, gasification temperature of 1500 K, pressure of 20 bar, and air-like gasification medium, the biomass gasifier's flow rate is higher at higher syngas rates. The results verified that there is an optimum ER for each syngas rate, in which the slow growth of the ER revealed the maximum gasifier biomass flow rate. For ER growth at lower levels, the specific fuel consumption (SFC) of the RGT Unit declines sharply from the maximum value reached at 0.27 kg/kW·h at an ER of 5% to the minimum value reached at 0.80 kg/kW·h at an ER of 25% for the lowest gasification temperature of 1000 K. Moreover, ER growths at low levels have a significant effect on the RGT plant's performance, leading to increased RGT thermal efficiency. The increase in the biomass moisture content led to a sharp decrease in the RGT thermal efficiency. The RGT thermal efficiency remains high at higher gasification pressure. The results revealed that the syngas lower heating value remains high at lower produced syngas rates. At the optimum ER, the H2 mole fraction depicted a value of 1.25%, 0.85% of CO, and 10.50% of CH4 for a lower heating value of 38 MJ/kg syngas. It is shown that the gasification air entered into the gasifier decreases amid the increase in the biomass moisture content. At different syngas rates (3–10 kg/s) and optimum ER, the results predicted that the Wood Chip biomass flow rates decrease when the gasifier efficiency increases. The simulation model revealed that ER growths at lower levels have a significant effect on increasing the power of the RGT plant. [ABSTRACT FROM AUTHOR]

Depressive disorders affect individual's thoughts, feelings, and social interactions. Enhancing emotional competencies of depressed individuals may alleviate their suffering. Purpose : This study aimed to compare depression severity and emotional intelligence before and after emotional intelligence training in patients with depressive disorders. Methods : A nonrandomized trial (one-group pretest–posttest) research design was applied to 69 patients purposively recruited. The patients' sociodemographic and clinical data were collected. The Beck Depression Inventory-II and Trait Emotional Intelligence Questionnaire-Short Form were completed before and immediately after an 8-weeks of focused weekly group training. Results : A significant improvement in the scores of well-being, self-control, emotionality, and sociability; total emotional intelligence scores; and total depression scores was perceived after training (Z = 5.601, 4.398, 5.686, and 3.516; 4.943; and 2.387, respectively). Implications for Nursing Practice : As emotional intelligence can be learned; it may be a target for interventions when dealing with patients with depressive disorders by strengthening their emotional intelligence.

The majority of entanglement measurement research concentrates on systems that can be represented by two interacting qubits. This is because there aren’t many researches that show analytical calculations for entanglement in systems with spin s > 1/2. In ref. (S.L.L. Silva Int. J. Theor. Phys. 60, 3861, 2021) the author used distance between states to study thermal entanglement in 2 ⊗ 3 Heisenberg chain. In this work various dynamic correlations as well as quantum Fisher information phenomena are studied in a 2 ⊗ 3 Heisenberg chain. First, we introduce our model for spin- 1 2 and spin-1 located in inhomogeneous magnetic field, then we obtain the eigenvalues and eigenvectors of Hamiltonian to deduce the thermal state matrix. On the other hand, the dynamic behavior of the system is studied by considering the system initially prepared in the thermal state. Also, the influence of both nonuniform and uniform external magnetic field on the degree of entanglement between the spin- 1 2 and spin-1 are discussed through some correlation functions, namely, concurrence, von Neumann entropy and geometric quantum discord. Finally we study the quantum Fisher information phenomena. [ABSTRACT FROM AUTHOR]

Post-orthopaedic operative pain is a serious concern that often requires the administration of analgesics; however, the optimal time of analgesic administration is still inconclusive. Perioperative analgesia is administrating pre-emptive analgesia before and during the surgery followed by postoperative analgesia to decrease the procedure associated nociceptive response. We aim to assess perioperative meloxicam versus postoperative meloxicam for pain control after orthopaedic operations. A systematic review and meta-analysis involving randomized controlled trials from PubMed, Embase, Scopus, WOS, and Cochrane until 28th May 2022. We pooled dichotomous outcomes using risk ratio (RR) presented with a 95% confidence interval (CI) and continuous outcomes using mean difference (MD) with 95% CI. We registered our protocol in PROSPERO with ID: CRD42022336046. We included five RCTs with 964 patients. All the included trials showed high risk of performance and detection biases because of lack of blinding. Pooled analysis favored perioperative meloxicam in reducing pain score after six hours (MD: −0.42 with 95% CI [−0.63, −0.21], p =.0001), 12 h (MD: −0.54 with 95% CI [−0.69, −0.39], p =.00001), and 24 h (MD: −0.23 with 95% CI [−0.36, −0.10]. Pooled analysis favored perioperative meloxicam in improving patient global assessment scale after 12 h (MD: −0.66 with 95% CI [−0.86, −0.46], p =.00001), 24 h (MD: −0.30 with 95% CI [−0.49, −0.11, p =.002), and 48 h (MD: −0.17 with 95% CI [−0.33, −0.01], p =.04). Pooled analysis favored perioperative meloxicam in reducing patient-controlled analgesia (MD: −4.25 with 95% CI [−5.96, −2.54], p =.00001). Short-term pain management after orthopaedic procedures is better accomplished with perioperative meloxicam than postoperative meloxicam. Before recommending perioperative meloxicam for pain control following orthopaedic surgeries, further multicentre trials are still warranted to examine the impact of perioperative meloxicam in different orthopaedic procedures.

In recent years demand for high speed and robust wireless networks are increasing due to the growth of accessing social networks from mobiles and computer systems. The recent solution for this is used by Fiber-Wireless (FiWi) network which it can provide the high throughput for end users. FiWi supports the mobility of wireless networks as well as high bandwidth of optical networks. But the major problem with these networks is as the number of mobile user's increases, queuing delay is increasing at FiWi's Optical Network Unit (ONU). Increasing queuing delay resulted into decreasing the throughput performance of FiWi networks. Hence, it is required to have efficient queuing method at ONU to allocate bandwidth efficiently to get high speed performance of FiWi; one of such methods is called as Dynamic Bandwidth Allocation (DBA). To solve the problem of increasing delay in FiWi networks due to increasing number of users, connection patterns and traffic congestion, in this work we proposed a multilevel, multi-queue based DBA method, so it is called Multilevel Multi-queue DBA. The innovation of the proposed method compared to previous methods provides a complete multilevel framework for reducing delays to an acceptable level. In proposed method, every ONU is configured with three levels of priority queues. The real time data is placed into the queue which is having the highest priority queue, while the non-real-time data is placed into other two queues depending on the threshold values set for them. This algorithm works according to different TDMA slots (those are treated as levels) in order minimize the congestion in FiWi Networks, so it can help to minimize the queuing delay performance. The proposed method is simulated and evaluated using MATLAB simulator. From the simulation results, it is showing that proposed DBA method is having better performance in terms of queuing delay and packet delivery ratio as compared to existing methods. The performance of FiWi networks is increased by 60% for proposed DBA approach whereas throughput is increased by 55% as compared to existing DBA method. The simulation results also show that queuing delay is minimized by 30% as compared to existing DBA method. [ABSTRACT FROM AUTHOR]

An exact analytic solution for two two-level atoms coupled with a multi-photon single-mode electromagnetic cavity field in the presence of the Stark shift is derived. We assume that the field is initially prepared in a coherent state and the two atoms are initially prepared in excited state. Considering the atomic level shifts generated by the Stark shift effect, the dynamical behavior of both quantum coherence (QC) measured using a quantum Jensen–Shannon divergence and of quantum correlations captured by quantum discord (QD) are investigated. It is shown that the intensity-dependent Stark-shift in the cavity and the number of coherent state photons plays a key role in enhancing or destroying both QC and QD during the process of intrinsic decoherence. We remarked that increasing the Stark-shift parameters, the frequencies of the transition for the mode of the cavity field, and photons number destroy both the amount of QC and QD and affected their periodicity. More importantly, QC and QD exhibit similar behavior and both show a revival phenomenon. We believe that the present work shows that the quantum information protocols based on physical resources in optical systems could be controlled by adjusting the Stark-shift parameters.

In the present work, the impact of heavily doped pockets near the source and drain side of tunnel CNTFET (T-CNTFET) is investigated. It has been found that inserting a heavily doped region constituting an N + pocket inside the channel at the source-channel junction boosts the ON-state performance of the conventional T-CNTFET which suffers mainly from low ON current. In addition, insertion of a highly doped pocket inside the channel and next to the drain overwhelms the ambipolar conduction which is also a major disadvantage of conventional T-CNTFET. In addition to the study of the DC performance indicators, the indicators of the high-frequency behaviour of the device are investigated in terms of the transconductance g m , overall capacitance C GG and cut-off frequency f T. It has been found that the length and the position of the pockets considerably affect the DC and high-frequency performance of the device. In this study, a quantum 2-D simulator which is based on non-equilibrium Green's function (NEGF) is used. For optimum pockets, it has been shown that the ON-state current can be increased up to about 9 times and the ambipolar current is suppressed down to about 10 times, compared to the conventional structure. While it has been observed that the source-side pocket enhances the high-frequency performance, the drain-side pocket deteriorates it. • Impact of heavily doped pockets near the source and drain side of tunnel CNTFET (T-CNTFET) is investigated. • Study of the DC performance of the proposed structure. • A quantum 2-D simulator which is based on non-equilibrium Green's function (NEGF) is used. • ON-state current can be increased up to about 9 times and the ambipolar current is suppressed down to about 10 times compared to the conventional structure. • The source-side pocket enhances the high-frequency performance, the drain-side pocket, deteriorates it.

Background: The frequency of malnutrition among hemodialysis (HD) cases differs widely depending on the study participants and assessment methods. Objective: This study aimed to estimation of the prevalence of malnutrition among hemodialysis adult patients in Zagazig University Hospitals by using different methods. Patients and Methods: At Zagazig University Hospitals, Nephrology Unit, Internal Medicine Department, we conducted our study on 95 patients with end-stage renal disease (ESRD) on regular hemodialysis. All patients underwent a thorough history-taking as well as laboratory investigations. Results: Mini-nutritional assessment had a statistically significant relationship with gender, body mass index (BMI), and dialysis duration. The mini-nutritional assessment (MNA) score, hemoglobin, hematocrit, serum iron, serum calcium, serum albumin, and high-density lipoprotein (HDL) cholesterol had a statistically significant positive correlation. Low-density lipoprotein (LDL) cholesterol is negatively correlated with the mini-nutritional assessment score. The correlation between Subjective Global Assessment (SGA) and BMI was statistically significant. Among factors significantly correlated to MNA score, only BMI (unstandardized β=0.978, 0<0.001) and serum albumin unstandardized β=1.625, p=0.004) significantly independently correlated with it. Conclusion: Chronic kidney disease patients who receive hemodialysis on a regular basis are more likely to suffer from malnutrition. Malnutrition becomes more common as people get older and their kidney function deteriorates. The MNA and SGA Score, when used as regular screening tools, revealed a significant risk of malnutrition and can be used during the treatment course and rehabilitation of ESRD patients.

Background: Diabetic kidney disease (DKD) has become the leading cause of the end-stage renal disease (ESRD) and it is one of the most devastating complications of type 2 diabetes mellitus (T2DM). Its pathogenesis encompasses multiple dysregulated epigenetic mechanisms. Long non-coding RNAs (lncRNAs) have an important function in various diseases. However, their roles in DKD remain mainly unknown. Objective: The present study was performed to explore the relative expression level of lncRNA taurine upregulated gene 1 (lncRNA Tug1) in Egyptian patients with T2DM and CKD and to investigate its associations with the progression of CKD. Patients and methods: This cross-sectional-controlled study included a total of 50 patients with T2DM and 50 age and sex-matched controls, attending at Internal Medicine, Faculty of Medicine, Zagazig University Hospitals. Quantitative real-time reverse-transcription PCR (qRT-PCR) was used to detect the expression levels of lncRNA TUG1. Results: patients with T2DM had statistically significantly lower values of the relative expression level of lncRNA Tug1 compared to the control group (1.313±0.72, vs 2.354±0.97, P =0.001). Interestingly, patients with macroalbuminuria (0.48±0.311) had statistically significant lower values of the relative expression level of lncRNA Tug1compared to patients with microalbuminuria (1.42±0.49) and patients with normoalbuminuric (1.86±0.636), P =0.01. In patients with DKD among studied variables, serum creatinine and UACR were the main independent parameters associated with the relative expression of lncRNA Tug1. Conclusion: It could be concluded that circulatory lncRNA Tug1 expression level is downregulated in patients with T2DM in a particular patient with macroalbuminuria. Thus, circulatory lncRNA Tug1 relative expression level may have a reno-protective role. [ABSTRACT FROM AUTHOR]

Background: Thoracotomy is a very painful surgical procedure that is used to get access into the pleural space, to the lungs, to the heart, to the esophagus or to get access to the thoracic aorta or anterior mediastinum. Objective: To study different modalities of treatment used for post thoracotomy pain control. Recent Findings: Inadequate post-thoracotomy analgesia enhances the postoperative stress response with deleterious effects on respiratory, cardiovascular, gastrointestinal, urinary, immune and coagulation systems. In addition to anxiety and increased risk of Post Thoracotomy Pain Syndrome (PTPS), which can interfere with normal life and may persist for years or even for life? Conclusion: Providing adequate post-thoracotomy analgesia can be challenging, as patients are often elderly or having multiple comorbidities. A multimodal approach is considered in managing post-thoracotomy pain starting with preemptive analgesia and cognitive behavioral modalities in addition to conventional multimodal systemic regimens as opioids, acetaminophen, NSAID, cyclooxygenase (COX)-2-specific inhibitors, gabapentin and pregabalin, steroids, IV lidocaine infusion, ketamine, and many regional analgesic modalities to avoid or decrease adverse effects of systemic regimens. These regional analgesic modalities include thoracic epidural blocks, thoracic paravertebral blocks, intrathecal opioid analgesia, serratus anterior plane blocks, intercostal nerve blocks, interscalene block, erector spinae block and interpleural block. [ABSTRACT FROM AUTHOR]

Background: Chest wall surgeries are accompanied by severe postoperative pain. Inadequate relief of this pain may lead to both pulmonary complications as lung atelectasis and infection and chronic post thoracotomy pain syndrome. Regional analgesic modalities are important portion of the multimodal therapeutic approach suggested for the management of post thoracotomy pain. Objective: To evaluate serratus anterior plane block as a regional analgesia technique for post thoracotomy and thoracoscopy pain. Recent Findings: Serratus anterior plane block (SAPB), a regional analgesic modality developed by Blanco et al. in 2013, has shown good analgesic effect after thoracotomy and thoracoscopy in many case reports and clinical trials. In such block, a local anesthetic is injected in the fascial plane deep or superficial to the serratus anterior muscle leading to block of lateral cutaneous branches of the intercostal nerves. This provides a sensory block of T2--T9 dermatomes. Conclusion: Serratus anterior plane block as a fascial plane block can be a preferred regional analgesia technique for both post-operative pain management with procedures involving anterolateral chest wall as thoracotomy, thoracoscopy and breast surgery and in cases of multiple rib fractures. This is owing to its easy technique, effective pain relief and potentially better side effects profile compared to other regional modalities and systemic opioids. [ABSTRACT FROM AUTHOR]

H 2 O 2 -modified graphite schist (GS) and sodium alginate (SA) interface was loaded by Fe 3 O 4 nanoparticles (MNPs) to prepare a magnetic biosorbent that was employed in removing Mn(VII) from solutions. The prepared GS/SA/MNPs adsorbent was investigated using a variety of techniques, including elemental mapping, TEM, XPS, FTIR, FESEM, EDX, XRD, XPS, and zeta potential. An experimental study supported by statistical physics calculations was carried out to obtain a new outline of the Mn(VII) uptake mechanism. The classical Freundlich and the statistical physical double-layer models adequately described the Mn(VII) uptake process at pH 3.0 and a temperature of 25–55 °C. The removed number of Mn ions (such as Mn+7 and Mn+2) per GS/SA/MNPs active site ranged from 0.70 to 0.84, indicating a mixed adsorption orientation driven by surface complexation and attraction forces mechanisms. The adsorption energies (∆ E) calculated by the double-layer model ranged from 18.79 to 24.94 kJ/mol, suggesting that the interaction between Mn(VII) and GS/SA/MNPs was controlled by physical forces. Increasing the adsorption capacity at saturation (Q sat) from 333.14 to 369.52 mg/g with temperature proposed an endothermic capture process. Thermodynamic functions clarified the viability and spontaneity of Mn(VII) uptake on the GS/SA/MNPs adsorbent. [ABSTRACT FROM AUTHOR]

Background: Congenital adrenal hyperplasia (CAH) is a common cause of urogenital sinus (UGS) anomalies. Delineating the abnormal anatomy of the UGS is crucial prior to the operative repair. Genitography and cystourethroscopy are commonly used by most surgeons to plan for reconstruction. We aim at this study to evaluate the role of these modalities and to compare their accuracy in delineating the abnormal anatomy. Methods: We did a prospective study of 30 female paediatric patients with persistent UGS secondary to CAH. All cases were evaluated with genitography and cystourethroscopy. We compared the accuracy of each modality in delineating the confluence. The confluence depth, the urethral length proximal to the confluence, the vaginal dimensions, and the depth of the bladder neck were measured in the genitograms. Results: Cystourethroscopy showed the abnormal anatomy in all 30 cases (100%). The genitogram showed the site of confluence in 24 cases out of 30 cases (80%). According to the site of the vaginal opening in relation to the external urethral sphincter in the genitogram, we had 2 groups: the low confluence group (N = 14) and the high confluence group (N = 16). The mean confluence depth in the low group was 9.8 mm vs. 20.5 mm in the high group (p-value < 0.001). To find a cutoff point to differentiate low from high groups, we used the values that resulted from dividing the length of the urethra proximal to the confluence over the depth of the bladder neck. By using the ROC curve, the cutoff point was 0.63 mm (< 0.63 mm high, > / = 0.63 mm low) (p-value <.001). Conclusion: We recommend using both cystourethroscopy and genitography for preoperative evaluation. Cystourethroscopy is superior in identifying the abnormal anatomy, but it lacks precision in taking measurements. Genitography can avoid this drawback and can precisely measure the confluence depth, vaginal dimensions, and length of the proximal urethra. We suggest using this formula (length of the urethra proximal to the confluence/depth of bladder neck) to classify persistent UGS as low (> / = 0.63 mm) and high (< 0.63 mm). [ABSTRACT FROM AUTHOR]

We focus on the effective generation of dynamical quantum correlations in a system consisting of a two two-level atoms interacting with a single-mode cavity field exposed to Ising interaction and dipole–dipole interaction (DDI) in the presence of intrinsic decoherence. By analyzing dense coding capacity (DCC), measurement-induced non-locality (MIN), and concurrence (C), we explore the dynamics of optimal dense coding, non-locality correlation, and entanglement, respectively. We investigate how Ising, dipole–dipole interactions, and the number of photons affect the behavior of these quantifiers in two different initial states: maximally and fully separable states. Our results demonstrate that we can improve all quantifiers by increasing the Ising interaction and decreasing the number of photons, whatever the initial state of the system (maximally or fully separable). Meanwhile, the impact of the DDI depends on the initial state of the system. Specifically, when the system is in an uncorrelated state, the DDI strongly stimulates the influence of intrinsic decoherence, thereby highlighting the occurrence of the entanglement sudden death phenomenon. However, a weak DDI interaction can significantly enhance quantum correlations and consequently give rise to the entanglement sudden. Additionally, other results will also be discussed.

This investigation was carried out to examine the safety and microbiological quality of products made from meat, dairy and vegetables. Samples of frozen food were examined for the presence of Gram-negative bacteria. A total of 49 frozen food samples were collected, including chicken nuggets, chicken fillets, chicken sticks, breaded breast chicken, fish, beef burger and minced beef roll, white cheese, camembert cheese, and vegetables (okra and green peas). Standard methods were used to determine the diversity of bacterial isolates in various food samples. About 182 isolates of Escherichia coli, 63 isolates of Salmonella typhi, 51 isolates of Pseudomonas, and 63 isolates of Klebsiella were recovered from the various frozen food samples. Meat samples showed a high prevalence of E. coli and Pseudomonas. The antibiotic susceptibility patterns of the isolated bacterial strains were also examined. Out of 12 antibiotics, only ciprofloxacin and ofloxacin showed a high level of susceptibility. According to the study's findings, the majority of the frozen meat product samples contained a significant number of bacteria and were therefore unsafe for human consumption. These microorganisms can cause infection and are therefore associated with a high risk to the consumers. Therefore, it is important to pay attention to health and education issues in relation to food safety. [ABSTRACT FROM AUTHOR]

The uncertainty principle restricts our capacity to precisely predict the measurement outcome of two incompatible observables. By taking into account two more particles as the quantum memories that correlate with the observed particle, the tripartite entropic uncertainty bound can be promoted. This paper discusses the impact of intrinsic decoherence on the dynamics of tripartite uncertainty bound (TUB) and residual entanglement in a three-qubit XXZ Heisenberg chain coupled to Dzyaloshinskii–Moriya interaction (DMI) and exposed to a uniform magnetic field; we consider the case where both interactions are working in the z-direction. To identify residual entanglement, we employ negativity (N) as an entanglement measure. The impact of different system parameters on the dynamics of residual entanglement, bipartite negativity, and TUB is discussed. We highlight the relationship between these entanglement measures (residual entanglement and bipartite entanglement) and the TUB. Two cases of initial state for the nearest-neighbor particle (A and B) are considered in this work: the maximally entangled state (Bell-state) and the separable state. Regarding the maximal entangled state, it has been observed that the negative effect of magnetic field is significantly stronger than the DMI in the presence of decoherence, and that it has the ability to completely destroy the entanglements and maximize TUB value. Moreover, it has been ascertained that we can improve the residual entanglement and TUB by controlling the decoherence rate. As for the separable initial state, it has been found that the DMI in this case stimulates the effect of intrinsic decoherence, which can highlight the entanglement sudden death phenomenon and reduce the accuracy of the prediction.

A system of N two-level atoms, Tavis-Cummings Dicke (TC-Dicke) model, interacting with a one-mode electromagnetic radiation field in the presence of the Stark shifts is studied, which is expected to predict new phenomena that are not explored in the original TC-Dicke model. We obtained the potential energy surface of the system using a trial state the direct product of coherent states in each subspace. In the frame of mean-field approaches, the variational energy is evaluated as the expectation value of the Hamiltonian for this state. The order of the quantum phase transitions is determined explicitly and numerically. We estimate the ground-state energy and the macroscopic excitations in the superradiant phase. Moreover, we investigated the critical properties of the TC-Dicke model in the classical spin limit and coherent state. We observed that in the thermodynamic limit, the energy surface takes a simple form a direct description of the phase transition. Moreover, it is found that when the microwave amplitude changes the new phase transition occurs with the Stark shift. The analytical solutions and numerical results, which appear in this paper are agreement with our paper which published recently in Int. J. Mod. Phys. B when we studied the same model using a different coherent state. [ABSTRACT FROM AUTHOR]

The proposed model contains four stroke two isochoric and two others adiabatic. A comparison of different models such that X X X , X X Z and X Y Z is examined for various thermodynamics quantities, especially the efficiency η and work W. Finally, discussion and interpretation all results are given in the last section. [ABSTRACT FROM AUTHOR]

Background: There is marked variety in Acute Kidney Injury (AKI) incidence and clinical characteristics as regards independent developmental risk factors and independent risk factors that could affect the outcome especially in critical care setting. Objectives: The aim of the work was to identify incidence and the clinical features of AKI in critical care situation and its impression on outcomes. Patients and Methods: A prospective cohort study in which patients were screened for AKI during the period from October 2018 to September 2019 using the AKIN criteria. Results: Incidence of AKI in critical care setting was 20.3% (63/310). The most independent risk factors for the development of AKI based on multivariate Logistic analysis were sepsis (p value: 0.000, estimated odds ratio: 4.492 and confidence intervals between 2.037 and 9.906) and chronic kidney disease (CKD) (p<0.001, estimated odds ratio: 8,982 and confidence intervals between 3,852 and 20,945). The most independent risk factor for poor AKI outcome was the need for renal replacement therapy (RRT) based on a multivariate logistic analysis (p<0.001, estimated odds Ratio: 3.649 and confidence interval between 1.145 and 4.050). Late nephrologist consultation comes in second place (p=0.002, estimated odds ratio: 4.902 and confidence interval between.463 and 9.316). Mortality in AKI group was 31% (3 patients in stage 2 and 17 patients in stage 3) compared to 42/247 (17%) in patients without AKI. Conclusion: The incidence of AKI in Zagazig University Internal Medicine ICU was 20.3 %. Sepsis was the most independent risk factor for the occurrence of AKI in ICU. The most independent risk factors for poor outcome following AKI development were the need for RRT, Late nephrologist consultation, longer duration of AKI and a high APACHE score.

Background: To many individuals with end-stage renal disease, kidney transplantation is the best option. Proteinuria and a lower glomerular filtration rate have been linked to metabolic syndrome, implying a connection to chronic kidney disease. The aim of the study is to evaluate the impact of metabolic syndrome on kidney transplantation outcome. Methods: This cohort study was conducted on 230 kidney transplant recipients in Urology and Nephrology Center, Mansoura University. We classified the included recipients into two groups; with or without metabolic syndrome. Records of all kidney recipients were reviewed for pre-operative details, operative details in addition to post-operative details. In each visit, recipients were subject to full history taking, thorough clinical examination and routine laboratory investigations. Radiological investigations were done as abdominal ultrasound (when indicated) in addition to graft grey scale ultrasound and doppler ultrasound if there is clinical suspicion of acute rejection, acute tubular necrosis, or renal artery thrombosis. Histopathological examination of the graft biopsy was carried out in cases of graft dysfunction. Results: Both groups were comparable regarding baseline data. Pre-transplant hypertension incidence was higher among the study groups. Tacrolimus was avoided in the study group. Incidence of rejection and other post-transplant medical complications was higher among the study group. Conclusion: Metabolic syndrome has a negative impact on kidney transplantation outcome. Metabolic syndrome is associated with higher incidence of acute rejection and acute tubular necrosis. [ABSTRACT FROM AUTHOR]

Background: Death with graft function (DWGF) is an important cause of long-term loss of grafts and patients. In this study, we investigated clinical characteristics and causes of DWGF among kidney transplant recipients in Mansoura from 2002 to 2019. Methods: From March 2002 to December 2018, 1,499 living donor renal transplants were done in Mansoura. Their data were retrospectively analyzed. Out of 285 reported deaths, 193 patients died with good graft function without the need for dialysis. Results: Death with graft function occurred in about 27% of kidney transplant recipients at a mean age of 36 +10.7 years. Males were 140 (72.5%). They reached end-stage renal disease (ESRD) secondary to GN in 14, PN in 35, PCK in 7, and nephrosclerosis in 12 patients. 125 patients had acute rejections (64.8%). Post-transplant hypertension occurred in 115 patients (59.5%), DM in 44 patients (22.9%), infections in 99 (51.5%), hepatic complications in 44 (22.9%), and malignancy in 25 patients (13%). Fatal infections in 60 patients (31.3%) were the main causes of death followed by cardiovascular causes in 29 patients (15.2%), liver cell failure in 20 patients (10.7%), and malignancy in 9 patients (4.6%). The mean serum creatinine at the last follow-up was 2 ± 0.6 mg/dl. Conclusions: In our study, DWGF constitutes of 27% of total graft loss. The most typical causes were fatal infections and CVS disease, respectively. DWGF develops due to co-morbid medical illness, pre-transplant dialysis, and other transplantation-related factors. Understanding different causes of death are mandatory to improve long-term outcomes. [ABSTRACT FROM AUTHOR]

Herein, magnetic iron oxide nanoparticles (MNPs) were impregnated with diatom frustules (DF) and sodium alginate (SA) to fabricate a magnetic bio-based adsorbent for the removal of methylene blue (MB) dye. The developed MNPs@DF/SA was characterized by XRD, TGA, DSC, FTIR, FESEM-EDX, TEM, and zeta potential techniques. Methylene blue (MB) adsorption was theoretically assessed at solution pH 8.0, adsorbent mass (50 mg), shaking time (4 h), MB concentration (100–400 mg/L), and different temperatures of 25, 40, and 50°C. A multilayer statistical model was the best in fitting the MB adsorption experiments at all solution temperatures. The number of MB molecules at each functional group (the steric n parameter) was between 1.16–1.33, which suggesting vertical geometry and multi-molecular mechanism. The adsorption capacity at saturation (Qsat) increased from 647.42 to 779.45 mg/g with increasing temperature from 25 to 50°C signifying an endothermic adsorption system. Extending the adsorption energies from 31.90 to 37.47 kJ/mol indicated that the MNPs@DF/SA – MB interactions were controlled by physical forces as electrostatic interactions. The fabricated MNPs@DF/SA reserved more than 79% of MB capture after five regeneration cycles, which recommended the suitability of this adsorbent in the removal of MB at an industrial level.
