Introduction We aimed to assess the accuracy of ultrasound elastography in detecting pediatric malignant cervical lymph nodes, and if this modality can obviate the need for surgical biopsies. Material and Methods A prospective study from September 2017 to September 2020 included 64 children with persistent cervical lymphadenopathy. Patients were evaluated by meticulous history and physical assessment. B-mode ultrasound, color Doppler, and sonoelastography were conducted thereafter. Elastography scans were classified into five patterns, and patterns from 3 to 5 were considered as malignancies. All children underwent open biopsies followed by pathological examination. Results of tissue diagnosis were compared with patterns of elastography to determine its accuracy. Results Twenty-eight patients (43.8%) had malignant nodes and the remaining 36 (56.2%) were due to benign causes. Elastography patterns of 1 and 2 were documented in 30 patients, and all of them were diagnosed as benign lesions. Patterns of 3 to 5 were demonstrated in 34 patients. Out of them, 28 were confirmed as malignancies, while 6 children were of benign nature (false positive). Ultrasound elastography achieved sensitivity and specificity of 100 and 85.7%, respectively, and an overall accuracy of 90.6% in the differentiation between malignant and benign entities. The overall accuracy of B-mode and color Doppler were 75 and 82.2%, respectively. Conclusion Elastography is a useful tool that should be added to ultrasound modalities during the diagnosis of pediatric cervical lymphadenopathy. Surgical biopsy in eligible patients is imperative to commence proper therapy or to discharge the child. Despite favorable results of elastography, it cannot replace surgical biopsy or change its indications.

Cupric oxide nanoparticles (CuO NPs) were phytofabricated utilizing leaf extract of Simarouba glauca and aerial extract of Celastrus paniculatus and are considered to hold excellent anticancer capability. Synthesized CuO NPs were characterized for their morphology, crystallinity, and structure. The presence of functional groups of phytochemicals on synthesized nanoparticles was validated by Fourier transform infrared spectroscopy (FTIR) analysis. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) examination reveal the uniform distribution of particles and the average particle size is 35 nm. The anticancer activities on MCF-7 and HT-29 cell lines revealed that CuO NPs synthesized using leaf extract of S. glauca (CuO-SG) induced cell death with half-maximal inhibitory concentration (IC50) value of 107.56 µg/mL and 208.57 µg/mL, while CuO NPs synthesized using the aerial extract of C. paniculatus (CuO-CP) indicated IC50 values of 97.39 µg/mL and 205.11 µg/mL, respectively. To be more precise for anti-cancerous effect, the molecular mechanism was examined in MCF-7 cell line treated with CuO-CP NPs by cell cycle analysis that depicted 75.28% of cell arrest in Sub G0/G1 phase and 71.29% of cells were gated in the late apoptotic phase of Annexin V and propidium iodide (PI) compared to control cells. The present work reports in vivo antitumor studies of CuO-CP NPs against Ehrlich ascites carcinoma (EAC) bearing C57 mice for the first time and was examined by variations in growth parameters, biochemical assays, hematological profile, and histopathological analysis. CuO-CP NPs could eliminate oxidants like lactoperoxidase and myeloperoxidase, stimulate reduced glutathione, restore the hematological profile and increase the life span of tumor-bearing mice treated by them in comparison with control.

Eighty, one-day-old commercial male broiler chicks (Ross 308), were distributed to four dietary treatments with two replicates of 10 chicks each, to study the effect of Synertox ® on broiler performance during aflatoxicosis. Birds were reared for 42 days. All birds were fed on diet with or without aflatoxin (AF) in feed, and with or without Synertox (ST) (enzymes, organic acids and yeast extract) in water. The treatments were as follow: T1 (0 ppm AF and no ST); T2 (2.5 ppm AF and no ST); T3 (0 ppm AF and 0.5 ml/l ST); T4 (2.5 ppm AF and 0.5 ml/l ST). Body weights and feed intake were recorded weekly. At 42 of bird’s age, five birds were randomly selected for estimation of antibody titres against Newcastle disease (ND; for calculation of the relative weight of bursa of Fabricius, thymus and spleen as well as for scoring liver and kidney lesions. The results show that the total body weight gain through 42 days of rearing period that the gain was highest in T3. In the second order was the weight of the control group (T1), while in the third order was T4. The worst body weight gain was reported in T2, in which chicks fed AF. The same picture in body weight gain was obtained with feed consumption and feed conversion ratio. AF had a significant negative effect on the liver parenchyma of broiler chicks in treatment 2, by changing liver colour from mahogany to enlarged muddy or even to yellowish discolouration, with friable consistency with sub capsular haemorrhages. The addition of Synertox® was effective in restoring the normal red brown liver colour. Kidney were also affected by feeding AF (T2). They were enlarged, swollen and pale in colour. All lymphoid organs tested, thymus, bursa of Fabricius and spleen were negatively affected by feeding AF in broilers at 42 days of age. Synertox® was effective in counteracting the negative effect of AF on relative bursal weight, thymus and spleen relative weights. Aflatoxin had detrimental negative effect on the ND ELISA mean antibody titre. A significant restoring of ND antibody titre to those of control group (T1) was recorded by addition of Synertox® to the drinking water of broilers in (T4) compared with the AF fed T2 group. From the studied parameters it could be concluded that Synertox® could be used in counteracting the negative effects of AF on health and performance of broiler chicks.

Background and objectives To compare the efficacy of autologous platelet-rich plasma (PRP), ablative fractional carbon dioxide (FCO2 ) laser, and their combination in the treatment of atrophic acne scars, both clinically and immuno-histopathologically. Study design/materials and methods Sixty patients were randomly divided into three equal groups. Group 1 received intradermal PRP injection sessions. Group 2 received FCO2 laser sessions. Group 3 received FCO2 laser followed by intradermal PRP injection sessions. Each group received three sessions at monthly intervals. The final assessment took place 3 months after the last session. Skin biopsies were obtained before and 1 month after treatment sessions with pathological evaluation. Results Combined PRP and FCO2 laser-treated patients had a better clinical response, fewer side effects, and shorter downtime than FCO2 laser alone. PRP-treated patients had some improvement but significantly lower than the other two groups. Conclusion The current study concluded that a combination of PRP and FCO2 laser is an effective and safe modality in the treatment of atrophic acne scars with better results than PRP or FCO2 laser alone.

De novo initiation by viral RNA-dependent RNA polymerases often requires a polymerase priming residue, located within a priming loop, to stabilize the initiating NTPs. Polymerase structures from three different non-segmented negative strand RNA virus (nsNSV) families revealed putative priming loops in different conformations, and an aromatic priming residue has been identified in the rhabdovirus polymerase. In a previous study of the respiratory syncytial virus (RSV) polymerase, we found that Tyr1276, the L protein aromatic amino acid residue that most closely aligns with the rhabdovirus priming residue, is not required for RNA synthesis but two nearby residues, Pro1261 and Trp1262, were required. In this study, we examined the roles of Pro1261 and Trp1262 in RNA synthesis initiation. Biochemical studies showed that substitution of Pro1261 inhibited RNA synthesis initiation without inhibiting back-priming, indicating a defect in initiation. Biochemical and minigenome experiments showed that the initiation defect incurred by a P1261A substitution could be rescued by factors that would be expected to increase the stability of the initiation complex, specifically increased NTP concentration, manganese, and a more efficient promoter sequence. These findings indicate that Pro1261 of the RSV L protein plays a role in initiation, most likely in stabilizing the initiation complex. However, we found that substitution of the corresponding proline residue in a filovirus polymerase had no effect on RNA synthesis initiation or elongation. These results indicate that despite similarities between the nsNSV polymerases, there are differences in the features required for RNA synthesis initiation.Author SummaryRSV has a significant impact on human health. It is the major cause of respiratory disease in infants and exerts a significant toll on the elderly and immunocompromised. RSV is a member of the Mononegavirales, the non-segmented, negative strand RNA viruses (nsNSVs). Like other viruses in this order, RSV encodes an RNA dependent RNA polymerase, which is responsible for transcribing and replicating the viral genome. Due to its essential role during the viral replication cycle, the polymerase is a promising candidate target for antiviral inhibitors and so a greater understanding of the mechanistic basis of its activities could aid antiviral drug development. In this study, we identified an amino acid residue within the RSV polymerase that appears to stabilize the RNA synthesis initiation complex and showed that it plays a role in both transcription and RNA replication. However, the corresponding residue in a different nsNSV polymerase does not appear to play a similar role. This work reveals a key feature of the RSV polymerase but identifies differences with the polymerases of other related viruses.

Tam Metin / Tez Bu tezde, Li-Fi sisteminde çoklu yolun veri iletimi üzerindeki etkileri iki şekilde incelenmiştir: MATLAB programı ile simülasyon ve Li-Fi sistemi tasarımı. İlk bölümde, verici ve alıcı arasında çoklu pozisyonlarda dört durum için sinyali gönderme ve alma durumu için parametreler hesaplanmıştır. Deneyler için tipik bir ortamı temsil eden bir oda belirlenmiştir ve görüş hattı (LOS) ve yansıyan sinyalleri (NLOS) takip eden sinyallerin etkisini belirlemek için simülasyon için MATLAB kullanılmıştır. LOS sinyali ile odanın dört duvarından yansıyan sinyaller arasındaki zaman gecikmesi, her bir durum için darbe süresi oranı ve bunun yapılabileceği maksimum veri hızı hesaplanarak belirlenmiştir. Bu simülasyonların sonuçları, Li-Fi sisteminin zaman gecikmesi, alınan sinyalin genliği, darbe süresi ve performansına etkisi üzerinden yansıyan sinyallerin alınan sinyali nasıl etkilediğini açıklamıştır. Maksimum OOK veri hızı veren bir sürede bir darbe yapılabilir. Verici ve alıcının en iyi konumu, maksimum veri hızı 105.93Mb/sn olan odanın merkezinde idi. İkinci bölüm, verici bölümündeki ana elemanları STM32F429 mikrokontrolör, transistör ve LED'ler ve alıcı bölümünde fototransistör ve OP-AMP AD848 elemanları kullanılarak Li-Fi sisteminin verici ve alıcısının tasarımıdır. Verici ve alıcı için sinyaller ölçülmüştür; yansıyan sinyallerin (NLOS) etkisini incelemek için iki ayna kullanılmıştır. Bu deneyin sonuçları, yansıyan sinyallerin (NLOS) alınan sinyalin genliğini artırarak alınan sinyali nasıl etkilediğini açıklamıştır. This thesis describes the effects of the multipath on data transmission over the Li-Fi system by two ways: they were by simulation by MATLAB program and design the Li-Fi system. First way was by calculating parameters for four cases of the sending and receiving signals between the transmitter and receiver in multiple positions. We set a room that represents a typical environment for our experiments, and use MATLAB for simulation to determine the effect of signals following direct line of sight (LOS) and reflected signals, or non-line of sight (NLOS). We determined the time delay between the LOS signal and the reflected signals from the four walls of the room with calculating the pulse duration rate for each case and maximum data rate that we can make it. The results of this simulation explained how the reflected signals affect the received signal by effected on the time delay, amplitude voltage of received signal, pulse duration and impact of the performance of the Li-Fi system. The LOS signal takes precedence over all reflected signals, but the last reflected signal causes extra time. So we could make a pulse in duration that giving maximum data rate of OOK. The best position of the transmitter and the receiver were in the center of the room that we can make maximum data rate 105.93 Mb/s.The second way was by design the transmitter and the receiver of the Li-Fi system by using the main elements in the transmitter section as the microcontroller STM32F429IDISCOVERY, transistor, LEDs and used the elements; phototransistor and OP-AMP AD848 in the receiver section,. The signals for the transmitter and the receiver were measured; we used two mirrors to study the effect of the reflected signals (NLOS). The results of this experiment explained how the reflected signals (NLOS) affect on the received signal through increasing the amplitude voltage received signal.

The fusion evaporation residue (ER) excitation function has been measured for $^{35,37}\mathrm{Cl}+^{181}\mathrm{Ta}$ reactions at energies above the Coulomb barrier. The measurements were performed using the HYbrid Recoil mass Analyzer at IUAC, New Delhi. Comparable ER cross sections have been observed in both reactions and there is no isotopic dependence. Measured ER cross sections were compared with theoretical calculations employing the dinuclear system model at projectile and target nuclei interaction and statistical model for the deexcitation of the formed compound nucleus. Larger ER cross sections at the complete deexcitation cascade of the formed compound nucleus are noticed in both reactions at higher excitation energies $({E}^{*}g80 \mathrm{MeV})$ over the calculated results. Fusion probability varies from $95%$ to $40%$ in the excitation energy range of the study. No appreciable difference in the fusion probability is noticed in the two reactions. Comparison of our results with other reactions populating $^{216}\mathrm{Th}$ shows a very strong entrance channel dependence.

In this paper, we give some direct approximation results by modified Kantorovich–Szász type operators involving Charlier polynomials. Further, approximation results are also developed in polynomial weighted spaces. Moreover, for the functions of bounded variation, approximation results are proved. Finally, some graphical examples are provided to show comparisons of convergence between old and modified operators towards a function under different parameters and conditions.

Many applications for these technologies have been reported in multiple fields, including dentistry, within the last three decades. It can be used in periodontology, endodontics, orthodontics, oral implantology, maxillofacial and oral surgery, and prosthodontics. In the present literature review, we have discussed the different clinical applications of various 3D printing technologies in dentistry. Evidence indicates that 3D printing approaches are usually associated with favorable outcomes based on the continuous development and production of novel approaches, enabling clinicians to develop complex equipment in different clinical and surgical aspects. Developing work models to facilitate diagnostic and surgical settings is the commonest application of these modalities in dentistry. Besides, they can also be used to manufacture various implantable devices. Accordingly, they significantly help enhance the treatment process, reducing costs and less invasive procedures with favorable outcomes. Finally, 3D printing technologies can design complex devices in a facilitated and more accurate way than conventional methods. Therefore, 3D printing should be encouraged in clinical settings for its various advantages over conventional maneuvers.

Introduction: Paliurus spina-christi Mill is a species with two varieties namely Paliurus spina-christi L. var. spina-christi and Paliurus spina-christivar. macrocarpa Beck native to mountains of Kurdistan, rarely growing in the upper plains of northern Iraq. Materials and Methods: A total of 15 plants from different parts of Kurdistan region were sampled. 30measurements for each characters of Leaf, Inflorescence, Flowers, Fruit, seeds, and leaf anatomical characters were measured for comparison between the two varieties. Results and Discussion: Fruit diameter of var. macrocarpa is significantly larger than fruit diameter of var. spina-christi. Most mean flower parts especially the ovary, in addition to seed size is larger in var. macrocarpa. Upper epidermal layer is always thicker than the lower epidermal layer for the same blade. The isobilateral mesophyll includes 2 layers of long palisade cells adaxially and 2-3 layers of short cells abaxially. Many vascular bundles are seen equally spaced in the mesophyll tissue.With the exception of the presence of simple hairs on the petiole adaxial side of the var. spina-cristi and the absence of these hairs from the same site of var. macrocarpa, all other anatomical features are considered to be of no taxonomic application. Stomatal density of the adaxial leaf side is up to 19 stomata per mm² in var. spina-christi while it is up to 38 stomata per mm² in var. macrocarpa. Conclusions: Both fruit diameter and the stomatal density of the adaxial leaf side constitute diagnostic characters for separating between the two varieties of Paliurus spina-christi Mill

BackgroundGalectin-3 is a s-galactoside-binding lectin. It has a role in many normal and pathologic processes, such as tumor cell growth, apoptosis, cell motility, invasion, and metastasis.ObjectiveTo study the immunohistochemical expression of galectin-3 in seborrheic keratosis (SK) as an example o

Background Aquaporin-3 (AQP-3), an aquaglyceroporin, has recently been ascribed a potential role in cell proliferation, migration, and tumorigenesis. Objective The aims of this study was to determine the expression and localization of AQP-3 in normal skin and detect its value in the pathogenesis of nonmelanoma skin cancer such as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) as well as inflammatory proliferative skin disorders such as psoriasis. Patients and methods The present study comprised a total of 186 samples, including 99 (33 with BCC, 33 with seborrheic keratosis, 3 with SCC, and 30 with plaque psoriasis) patients, 57 (27 SCC and 30 keratoacanthoma) paraffin blocks, and 30 healthy control skin specimens. Biopsies were obtained from the lesional and control skin samples, and examined by hematoxylin and eosin staining and immunohistochemically for AQP-3 expression. Results There was a statistically significant downregulation of AQP-3 expression between all the cases and control, except in BCC where there was no significant downregulation. BCC had the highest mean value followed by psoriasis, keratoacanthoma, seborrheic keratosis, and finally SCC. Poorly differentiated SCC had the lowest mean value in SCC degrees. Conclusion The AQP-3 expression was downregulated in the disease groups as compared with normal human skin from the control group, and was decreased in poorly differentiated tumor cells compared with differentiated tumor cells, suggesting that AQP-3 may have a role in the differentiation of these tumors more than proliferation. Therefore, AQP-3 may be considered as an antihyperproliferative prodifferentiative marker.

Nowadays, the concern of vehicle manufacturers towards improving engine performance, reducing fuel consumption and exhaust emissions that can cause the pollution of the atmosphere, concerns of strict emission pollution control regulations. Intercooler heat exchanger devices are used for engine charge air temperature improving for engine performance and emissions reduction. This paper introduces a new add-on technology of intercooler heat exchanger- (IHE) developed for utilizing in intake charge air density enhancement in engine combustion for better performance. Presenting a challenge in contributing a framework process for geometry designing development procedure for accurate and reliable scale design size of an air-vapour gas shell-and-tube IHE type, used refrigerant coolant medium. The process presents effective IHE in design time consumption, accurate in scale with higher performance and reliability operation in all environment weather due to reversibility system. A selected design geometry of 60 bunches of tubes with 7.53 mm inner diameter and 150 mm long placed. Effectiveness and design parameter geometry calculation are conditions of the IHE dependent relations of the shell size to tube length in condition of engine space availability control. Pressure drop and cooling capacity of IHE configuration design are proportional to the availability of design space or pressure drop control by the engine. Numerical and simulation results expressed a significant ability of IHE of 2–13 kW cooling load and process applicability for qualified design geometry configuration for selected IHE type. The developments present significant geometry flexibility design with the ability of cooling load or heating effect if reversible system, which offered multipurpose use in widely all vehicle types. © Universiti Malaysia Pahang, Malaysia.

Evaporation residue cross sections are measured for the reaction $^{48}\mathrm{Ti}+^{138}\mathrm{Ba}$ which forms the compound nucleus ${}^{186}{\mathrm{Pt}}^{*}$. The cross sections are measured at beam energies in the range of 189.3--234.4 MeV. The experimental evaporation residue cross sections are compared with the dynamical model which employs one-dimensional Langevin dynamical calculations. The dissipation strength of the Langevin equation is calculated using both chaos weighted wall formula and a constant reduced dissipation function. The measured ER cross sections are found to be much less than the theoretical predictions. Further, the measured ER cross sections for the system $^{48}\mathrm{Ti}+^{138}\mathrm{Ba}$ are compared with those of $^{32}\mathrm{S}+^{154}\mathrm{Sm}$ forming the same compound nucleus. The suppression in the evaporation residue cross sections of the former reaction may be attributed to the increasing competition from quasifission. The quasifission reaction is found to have superseded any effect of neutron shell closure $(N=82)$ of the target in the present study.

This work highlights how the treatment of ZSM-5 (parent Zeolite Socony Mobil&ndash, 5, Si/Al = 23) with different surfactant templates and alkaline solution, improved the catalytic performance in the Friedel-Crafts acylation of anisole with a propionic anhydride to obtain p-methoxypropiophenone. The modified microporous to mesoporous zeolite catalysts were characterized using different analytical techniques, including X-ray diffraction (XRD), nitrogen porosimetry, Fourier-transform infrared spectroscopy (FT-IR), temperature-programmed desorption (ammonia-TPD) and field emission scanning electron microscopy (FE-SEM) to analyze the crystallographic structure, surface acidity, surface area, porosity, morphology, and particle size. The results showed that the formed mesoporous zeolite by NaOH solution had smaller mesopores (ca. 3.7 nm) as compared to the mesoporous zeolites obtained by surfactant templates, such as, CTAB (ca. 14.9 nm), TPAOH (ca. 11.1 nm) and mixture of CTAB/TPAOH (ca. 15.2 nm). The catalytic acylation reaction was conducted in a batch glass reactor at various temperatures and the products were analyzed using off-line gas chromatography&ndash, mass spectrometry (GC-MS). It was found that the activity of treated ZSM-5 with mixed surfactant templates (CTAB/TPAOH) exhibited enhanced selectivity towards the main product (p-methoxypropiophenone) by a factor 1.7 or higher than unmodified ZSM-5 due to its increased surface area by 1.5 times and enhanced acid sites.

Evaporation residue cross sections for the $^{16}\mathrm{O}+^{203,205}\mathrm{Tl}$ reactions were measured at laboratory beam energies in the range of 82--113 MeV using a gas-filled separator. Transmission efficiency of the separator was estimated using a calibration reaction $^{16}\mathrm{O}+^{197}\mathrm{Au}$ and by simulating the evaporation residues angular distributions. Statistical model calculations were performed for both the measured systems. These calculations overestimate the experimental evaporation residue cross sections. This could be attributed to the presence of noncompound nuclear fission. An estimation of noncompound nuclear fission contribution was carried out. Comparison with neighboring systems shows that a slight change in the entrance channel or the compound nucleus properties makes a large difference in evaporation residue cross sections.

Neutron multiplicity excitation function has been measured for the $^{30}\mathrm{Si}+^{197}\mathrm{Au}$ reaction populating the $^{227}\mathrm{Np}$ compound nucleus at excitation energies in the range 44.1--78.8 MeV using the National Array of Neutron Detector facility of Inter University Accelerator Centre, New Delhi. Measured pre-scission neutron multiplicity values are analyzed using a statistical model incorporating Krammer's fission width due to the dissipative drag in nuclear fission, shell corrections in fission barrier and level density, collective enhancement of level density, and $K$-orientation effect. The present work demonstrates that a strong fission hindrance is essential to reproduce the experimental pre-scission neutrons, whereas the temperature dependent dissipation coefficient as observed in a few recent measurements is not required to reproduce the experimental ${\ensuremath{\nu}}_{\mathrm{pre}}$ data. No substantial effect of collective enhancement of nuclear level density and tilting away effect of compound nucleus spin on neutron emission prior to the scission configuration was observed unlike fission of preactinides.
