Hyponatremia is common in inflammatory diseases such as meningitis. Also, it has been found to be strongly associated with the degree of inflammation. However, it has not been fully evaluated in lupus. This study aimed to assess the inflammatory impact of hyponatremia in SLE patients and investigate its relationship with SLE disease activity.Patients and Methods: A total of 101 patients with SLE were enrolled in this study and divided into two groups according to Na level; a normo-natremic group and a hyponatremic group. Demographic and clinical data were collected. SLE activity was assessed by the systemic lupus erythematosus disease activity index (SLEDAI). The estimated sedimentation rate (ESR) as well as levels of C-reactive protein (CRP) and complements (C3 and C4) were measured.Results: The majority of patients were females (98 subjects) (97%) with a mean age of 33± 8 years. Out of 101 participants, 40 patients (39.6%) were hyponatremic with a mean Na level of 131.58± 3.11 mmol/L. There was a statistically negative correlation between both ESR and SLEADI score and Na level (r=− 0.436 and − 0.436, respectively) with p=0.002, whereas Na level was positively correlated with complements, Cl, and albumin levels (r=0.653, 0.314, and 0.460, respectively) (p=0.000, 0.027, and > 0.001, respectively). CRP was not correlated with Na level. ESR was independently correlated with hyponatremia at the 95% CI for Exp B (0.997– 0.058) with a p-value of 0.048.Conclusion: Hyponatremia could be used as an indicator of SLE activity. Also, it might be an easily and rapidly detected as well as a prognostically useful marker of inflammation.Keywords: lupus erythematosus, activity, hyponatremia, complement, inflammation

Effective project management is crucial for the successful delivery of construction projects, ensuring they are completed on time, within budget, and to the desired quality standards. Project scope definition is at the heart of project management, which forms the basis for project planning, execution, and control. However, despite its importance, there is a lack of comprehensive investigation into project scope definition compared to other areas of management knowledge. This research paper identifies the key enablers and elements of project scope definition, as well as their relative importance. Moreover, this study develops an assessment model using the Analytic Hierarchy Process (AHP) to evaluate the completeness of the project scope definition. Data was gathered through a questionnaire survey deployed to subject matter experts specialized in building projects in Saudi Arabia. The results highlight the significance of understanding the direct impact of scope definition on project success, which emerged as the most influential enabler in facilitating scope definition. Among the top ten elements of scope definition are project financial requirements, regulatory requirements, and building site location and geotechnical data. The findings and AHP assessment model can assist project stakeholders and managers in effectively defining project scope, potentially leading to efficient management of building projects.

BACKGROUND: Multiple myeloma (MM) represents the second most common hematologic malignancy (15%). Induction with bortezomib, cyclophosphamide, and dexamthasone VCd (d: low dose dexamthasone) regimen is widely used due to its high effectiveness, low toxicity and good tolerability, particularly with renal impairment. Real-world data on the use of VCD in clinical practice is lacking. OBJECTIVES: Evaluate the real-world experience of the VCD regimen DESIGN: Retrospective SETTING: Tumor registry database of tertiary cancer care center PATIENTS AND METHODS: Newly diagnosed MM patients who received VCD induction and underwent autologous stem cell transplant (ASCT) from July 2007 to July 2020 MAIN OUTCOME MEASURES: Response evaluation, progression-free survival (PFS) and overall survival (OS). SAMPLE SIZE: 87 patients RESULTS: Of 102 patients who started induction with VCd, 87 patients experienced a partial response or more overall response rate of 85%). The median age of these 87 patients at diagnosis was 52 years, of which 29.9% presented with renal impairment and 60.3% of patients had stage 2 by the Revised International Staging System (R-ISS). Patients with a standard cytogenetic risk achieved a better response compared to those with a poor cytogenetic risk (P=.044). The post-induction response rates were 6.9% stringent complete remission (sCR), 35% complete remission (CR); 41.4% very good partial response (VGPR), and 16.1% partial response (PR), respectively; the response rates became greater for sCR and CR post-transplantation at day 100 with 16.1% sCR, 35.6% CR, 32.2% VGPR and 16.1% PR, respectively. The median PFS was 49 months and 5 years OS was 84%. PFS was better in patients who achieved sCR vs PR (83 vs 35 months, P=.037). High LDH, high-risk cytogenetic and stage 3 R-ISS showed a worse median PFS and OS. CONCLUSIONS: VCD induction in newly diagnosed MM is highly effective, convenient, tolerable and affordable regimen, especially in low and middle-income countries with limited resources, also with favorable outcomes and survival. while those who did not respond successfully shifted to VRD or VTD. LIMITATIONS: The usual limitations of a retrospective analysis using registry-level data, no data on quality of life.

Abstract Background An inflammatory disorder known as trigger finger (TF) results in pain in the proximal and distal palm and digit, as well as restricted movement and diminished function. Physiotherapists use a specific treatment called dry needling (DN) to reduce musculoskeletal pain and assist patients with mobility restriction. Objectives This study aimed to examine the effectiveness of DN on quality of life in patients suffering from trigger finger. Methods Forty patients, ranging in age from 45 to 75, were randomized into one of two groups in this Prospective pre and post-test, single-blind parallel group randomized controlled trial. Twenty patients were assigned to the intervention group, which included traditional physiotherapy splinting and ultrasound (ultrasonic dosage was 3MHz, the intensity of 0.5 W/cm2, and the duty cycle 50%. Duration: 5 minutes) as well as to DN upon a nodule at the proximal end of the 1st annular (A1) pulley as well as the discrepancy that existed between the flexor tendon's diameter along with its sheath at the metacarpal head. Twenty patients were assigned to the control group, which consisted of traditional treatment alone, twice weekly, for a total of ten sessions over five weeks. The trial evaluated the quality of life, severity of pain, and hand grip strength using the World Health Organization Quality-of-Life Scale (WHOQOL-BREF), visual analogue scale, and Camry dynamometer respectively two times, beforetreatment and after 10 treatment sessions. Results Within-group analysis using MANOVA demonstrated a significant decline in VAS (p = 0.001) and a significant improvement in quality of life (p = 0.001) and hand grip strength (p = 0.001). Regarding between group comparison using MANOVA there was significant improvement in favor of the DN intervention (p = 0.001) for all measured variables. Conclusions A 5-week dry needling approach with a traditional physiotherapy program was effective in improving in quality of life, pain intensity, and hand grip strength in patients with trigger finger, emphasizing it as the better option.

Abstract The present study was conducted in the Laboratory of Tissue Culture, Horticulture Department, Faculty of Agriculture, Damietta University, Egypt. The objective of this study was to establish a micropropagation protocol suitable for three imported peach rootstocks: Okinawa (P. persica), Nemared (P. persica × P. davidiana) × P. persica), and Garnem (P. dulcis × P. persica) in vitro. The results showed that soaking the explants in sodium hypochlorite (NaOCl) at 20% for 15 min produced the highest responsiveness (82.81%), survival (96.61%), with the lowest mortality (3.14%) and contamination (0.24%). Explants of the Garnem genotype had the best response (89.12%), survival (90.62%), lowest mortality (0.00%), and highest contamination (9.37%) when compared to the other genotypes. In comparison with axillary buds, the shoot tip displayed the highest responsiveness, survival, and death (100, 87.40, and 12.59%, respectively), as well as the least significant contamination (0.00%). Additionally, the percentages of responsive, survived, dead, and contaminated explants at the various collection dates varied significantly. The 6-benzylaminopurine (BAP) concentrations used (3 to 5.0 mg/L) demonstrated similar behavior in terms of in vitro proliferation, with rates of 3.77 to 6.11, 4.33 to 8.88, and 3.33 to 7.44 shoot numbers per explant for the Okinawa, Nemared, and Garnem peach rootstocks, respectively, indicating that the number of shoot proliferations is genotype-dependent. Additionally, using 5.0 mg/L BAP in combination with 0.2 mg/L IBA significantly increased average shoot proliferation (96.29%), number of shoots per explant (7.48), and average leaf number/explant (16.33) compared to the other treatments. Based on these results, adventitious bud development was enhanced during in vitro multiplication of the Okinawa, Nemared, and Garnem peach rootstocks by the synergistic interaction of indole-butyric acid (IBA) and 6-benzylaminopurine (BAP).

The main purpose of this paper is to investigate the impact of the thermal processing of natural fibers on the strength of what is considered fiber-reinforced concrete. Natural fibers extracted from palm trees and bamboo residues were collected and pyrolyzed. The investigation of the morphological alterations that occur during the pyrolysis of natural fibers at a temperature of 200°C showed the impact of the cementitious environment on this process. In addition, the mechanical characteristics of fiber-reinforced concrete were conducted on different dosages (1, 1.5, 2, and 5% wt.) of treated and untreated palm oil, date kernel, and bamboo fibers. The results demonstrated that the inclusion of fibers up to 1.5% wt. enhanced the concrete mixes mechanical properties, which included pyrolyzed fibers. Analyzes of the concrete microstructure revealed that the treated fibers were not damaged. The 1.5% wt. addition of fibers after pyrolysis process can effectively improve their adhesion to the matrix and reduce the width and number of cracks. The analysis of variance results for flexural strength indicated that all sources had no significant impact on the flexural strength of untreated or pyrolysis treated natural fiber reinforced concrete.

Abstract Background Today, low back pain is a serious global health issue. Currently, 85% of low back pain is caused by muscular imbalance and is a result of Lower cross syndrome (LCS), which are chronic postural defects. The physical therapy technique known as Global Postural Re-education (GPR) was created in France and is based on the concept that muscle chains make up the entire muscular system. Aim The purpose of this study was to investigate the effect of global postural re-education on low back pain patients with lower cross syndrome. Design Prospective pre and post-test, single-blind randomized controlled trial. Setting Outpatient physio therapy clinic at Damanhur teaching hospital. Population Fifty participants (25 to 40 years old) suffer from low back pain with lower cross syndrome. Methods Participants were randomly assigned to two equal groups: global posture re-education approach and conventional physiotherapy was given to study group "A" and conventional physiotherapy was given to control group "B" throughout the course of 15 treatment sessions, twice sessions weekly. The patients' pre- and post-treatment progress was assessed using the clinometer digital smartphone application to measure anterior pelvic tilting, flexible ruler to measure lumbar lordosis, Modified Thomas test to measure hip flexor flexibility, Visual analogue scale (VAS) to measure pain and Oswestry Low Back Pain Disability Questionnaire Arabic version to measure function disability. Results Comparing the study group and the control group after treatment showed that the study group had a significantly lower anterior pelvic tilting (P = 0.001), lower lumbar lordosis (p = 0,024), higher flexibility of hip flexor muscle (p = 0,001), lower VAS (p = 0,001) and improving in function disability (p = 0,001) compared to the control group. Conclusion Adding a Global postural re-education approach is thought to be effective in treating low back pain patients with lower cross syndrome. Clinical Rehabilitation Impact Global postural re-education approach decreases anterior pelvic tilting angle, lumbar lordotic angle, pain, and disability caused by low back pain and increase hip flexor flexibility.

ABSTRACT Yellow fever mosquito, Aedes aegypti, has been associated with several severe human diseases. Larvae and adults of Ae. aegypti has been widely studied, but pupae have not received much attention. In this study, external morphology and chaetotaxy of Ae. aegypti pupae were investigated using scanning electron microscopy (SEM) to determine additional morphological characteristics for proper species identification. Ae. aegypti pupae exhibit high mobility with rapid submergence in response to external disturbances. Pupae contact air through paired respiratory horns. A pupal body is covered with a translucent cuticle composed of a cephalothorax and a narrow, articulated abdomen. Anterior region of cephalothorax is occupied by mouthparts and a flattened head. Adult's compound eyes are visible on both sides of their head. Before compound eyes, antennae emerge in upper part and are bent in reverse along sides of thorax. First abdominal segment has two straightforward palmate bundles, essential for maintaining pupal body above water's surface. Compared to other eight abdominal segments, ninth is relatively tiny; it holds a couple of movable appendages called paddles which are fundamental organs in pupal movement, and a midrib supports them. This morphological analysis of pupae attributes of Ae. aegypti is critical for controlling mosquito-borne diseases and taxonomy.

Radio Occultation (RO) is pivotal for profiling the neutral and ionized atmosphere, with the PlanetiQ mission, via its GNOMES satellites, striving to establish an advanced atmospheric observing system. However, an assessment of the spatiotemporal distributions of PlanetiQ observations and comparisons with reliable datasets are lacking. This study addresses this gap by examining the temporal and spatial distribution of RO observations from PlanetiQ during its initial 198 operational days in 2023, alongside comparisons with COSMIC and Numerical Weather Prediction (NWP) models. Data from GN02, GN03, and GN04 satellites, yielding 1099, 1313, and 1843 RO events per day, respectively, were analyzed. The satellite constellation’s observations demonstrate a generally well-distributed pattern, albeit minor deficiencies in equatorial and polar regions. Single-profile comparisons with COSMIC data reveal strong correlations for pressure, temperature, Water Vapor Pressure (WVP), and refractivity profiles, with temperature exhibiting larger variations (RMSE = 1.24 °C). Statistical analyses confirm statistically insignificant differences between the PlanetiQ and COSMIC profiles at the same spatio-temporal coordinates. Comparisons with NWP models show slight differences with GFS, with overall RMSE values of 0.23 mb (WVP), 0.6 mb (pressure), 1.3 (refractivity), and 1.5 °C (temperature). However, assessments against GFS/ECMWF models indicate overall compatibility, with insignificant differences between PlanetiQ profiles and model observations.

Abstract Background Despite the increased interest in publishing data on central neurocytoma, its management remains controversial. The overall incidence is approximately 0.5% of brain tumors. The reporting of institutional experience is of major need for such category of tumors to increase our knowledge and experience. In this study, we describe the clinical presentation, pathological data, and treatment outcomes of central neurocytoma. Results Medical records of patients with neurocytoma treated in our center from July 2008 to December 2018 were retrospectively reviewed. Extra ventricular neurocytomas were excluded from analysis due to the known aggressive behavior compared to central neurocytoma. Seventeen patients treated at our center as central neurocytoma were included in the study. The frequent clinical presentation was headaches (58.8%) and paresis (35.3%). Ten patients (58.8%) developed symptoms before the age of 30 years. All patients were treated with surgical resection. Gross total resection was performed in 11 cases (64.7%) and subtotal resection was performed in 3 cases (17.7%). Four patients developed disease progression following the first excision (23.5%), for which additional resection was performed. Two patients received fractionated radiotherapy; one after the first resection due to residual disease postoperatively and the other patient following the third excision due to multiple recurrences with radiotherapy doses of 50.4 Gy and 54 Gy, respectively. The median follow-up time was 51 months (range of 14–106). The 5-year progression-free survival was 70 ± 13%. The overall survival for our cohort of patients was 100%. Conclusions Central neurocytoma is a rare tumor of neuronal origin and surgery is the mainstay of treatment with a favorable prognosis. Adjuvant radiotherapy can be offered in patients with residual disease or multiple recurrences, especially in patients with tumors of high MIC-1 LI.

Ransomware is a type of malicious software that encrypts a victim’s files and demands payment in exchange for the decryption key. It is a rapidly growing and evolving threat that has caused significant damage and disruption to individuals and organizations around the world. In this paper, we propose a comprehensive ransomware classification approach based on the comparison of similarity matrices derived from static, dynamic analysis, and visualization. Our approach involves the use of multiple analysis techniques to extract features from ransomware samples and to generate similarity matrices based on these features. These matrices are then compared using a variety of comparison algorithms to identify similarities and differences between the samples. The resulting similarity scores are then used to classify the samples into different categories, such as families, variants, and versions. We evaluate our approach using a dataset of ransomware samples and demonstrate that it can accurately classify the samples with a high degree of accuracy. One advantage of our approach is the use of visualization, which allows us to classify and cluster large datasets of ransomware in a more intuitive and effective way. In addition, static analysis has the advantage of being fast and accurate, while dynamic analysis allows us to classify and cluster packed ransomware samples. We also compare our approach to other classification approaches based on single analysis techniques and show that our approach outperforms these approaches in terms of classification accuracy. Overall, our study demonstrates the potential of using a comprehensive approach based on the comparison of multiple analysis techniques, including static analysis, dynamic analysis, and visualization, for the accurate and efficient classification of ransomware. It also highlights the importance of considering multiple analysis techniques in the development of effective ransomware classification methods, especially when dealing with large datasets and packed samples.

Tumors at the craniocervical junction represent a formidable challenge due to its intimate association with the medulla and cervical spinal cord, lower cranial nerves, and vertebral artery (VA). Foramen magnum meningioma (FMM) reparents 2% of all intracranial meningiomas and 4% of posterior fossa meningiomas. The far lateral approach is preferred for FMM with VA involvement. Here, we describe a case of a 58-year-old woman who presented with headache, nausea and vomiting and gait disturbance and was found to have large FMM encasing the dominant VA. The patient was treated with a left far lateral approach with limited condylectomy resulting in gross total resection and preservation of lower cranial nerves function.

Maternal glucose is the principal macronutrient that sustains fetal growth. Prolonged exposure of the fetus to hyperglycemia from the early stages of pregnancy accelerates the maturation of the stimulus–secretion coupling mechanism in β cell autoimmunity, which leads to early hyperinsulinemia in type 1 diabetes mellitus (T1DM). Nowadays, diabetes mellitus (DM) is the most common medical complication of pregnancy, and among young women, the prevalence of overt diabetes and undiagnosed hyperglycemia is rising. Even though conventional medication is effective in treating DM, it is expensive and has harmful side effects. Herbal medicine will thus incorporate alternative therapy and be more effective and less toxic. Due to their bioactive components, olive leaves (Olea europaea) are frequently used medicinally; however, little is known about how this plant affects the immune system when it comes to diabetes. The current study used a pregnant mother rat model of alloxan-induced T1DM to examine the antidiabetic properties and embryonic safety of olive leaves. Forty adult female Sprague Dawley rats were split up into four groups as follows: nondiabetic, diabetic, olive, and diabetic-olive groups. All the mother rats were sacrificed on the 20th day of pregnancy, and fetuses were collected for further investigations. In diabetic pregnant mothers, fetuses had systemic modulation-negative effects. These effects were significantly reversed when the diabetic groups were supplemented with extracts from olive leaves. The findings showed that the olive leaf extract inhibits the diabetogenic effect mediated by alloxan with effective and protective systemic immunomodulation during embryonic development.

Mosquito‐borne viruses continue to affect billions of people globally, posing a severe health risk and an economic burden. Aedes albopictus (Skuse), a highly invasive mosquito species, has repeatedly invaded and increased its presence, serving as a key vector of dengue virus, yellow fever virus (YFV), Zika virus (ZIKV), and Chikungunya virus (CHIKV), causing frequent outbreaks of related viral diseases. This study investigated the impact of larval diet quantity on larval duration and adult body size. The effect of adult mosquito body size on various aspects of Ae. albopictus was also examined, including blood‐feeding behavior, follicular development, reproductive capacity, egg retention capacity, preoviposition period, and fecundity. These diverse characteristics all have an effect on arboviruses transmission. The changes in body size (small, medium, and large) are obtained by providing different quantities of larval diet (low, average, and high). The results indicate that the quantity of larval diet directly impacts the adult body size while inversely affecting the larval duration. Furthermore, a positive correlation exists between adult body size and wing length, implying that wing length could be a reliable indicator of adult body size and rearing conditions during the developmental stages. Large females exhibited higher numbers of follicles and greater fecundity. Moreover, a significant correlation was observed between follicle number before the first blood meal and total egg number. In contrast, increasing wing length decreased the number of blood meals, egg retention, and the preoviposition period. The tendency of small females to perform multiple feedings was greater than that of large females. Small females exhibited a higher propensity for multiple feeding activities when compared to their larger counterparts. Most medium‐sized females (92.8%) deposited eggs in their ovaries, however, 7.2% retained a few. In contrast, most large females (87.4%) had complete ovary egg‐laying, whereas a minority (12.6%) retained some of their eggs. About 35.2% of small females showed ovarian egg retention, while 64.8% successfully laid all their eggs. After the first blood meal, the oviposition rate was 92% for large females, 88% for medium females, and 76% for small females. About 69.86% of the follicles in large females underwent vitellogenesis. This finding suggests that small females with low energy reserves exhibited incomplete oviposition and multiple blood feedings to increase their reproductive capacity. Research Highlights: Add more information about arbovirus epidemics and their consequences.Aedes albopictus is a global invasive species that transmit dengue virus, CHIKV, YFV, and ZIKV.A negative correlation was observed between body size, egg retention, and multiple blood feedings in Aedes albopictus.Size of the female's body was positively correlated with fecundity, while it was negatively correlated with the preoviposition period.Size‐dependent multiple blood feeding affects vector‐host contact frequency.

Aim of the Work: To evaluate the role of Alendronic acid (Fosamax), vitamin K2, and/or fennel essential oil in treating ovariectomy-induced osteoporosis in adult female albino rats. Materials and Methods: Forty-eight adult female Wistar albino rats weighing 180±20g, aging 12-14 weeks were divided into the following groups: Group I (control group). Group II (sham-operated group), and group III (ovariectomized group). Bilateral ovariectomy (OVX) was performed for thirty rats and twelve weeks later, rats were further subdivided equally into five subgroups. Group IIIa (osteoporotic group); Group IIIb (Fosamax-treated group).Group IIIc (Mena Q- treated group); Group IIId (Fennel oil-treated group); Group IIIe (Mena Q and Fennel-treated group). All treatments were administered by oro-gastric tube and were continued for 12 weeks. Serum analysis was assessed for the appropriate laboratory tests. Femur bone specimens were processed for histological examination. Morphometric and statistical analyses were performed. Results: The osteoporotic group showed a non-homogenous acidophilic matrix with osteoporotic cavities, large bony tunnels, areas devoid of osteocytes, empty lacunae, and unevenly eroded endosteum. These findings were supported by a significant decrease in serum calcium and phosphorus levels coupled with a significant increase in levels of the enzymes bone-specific alkaline phosphatase and tartrate-resistant acid phosphatase and a significant reduction in the area percentage of collagen fibers and Periodic-Acid-Schiff reaction within the bone matrix. The immunohistochemical studies detected a positive RANKL immune expression in the osteoporotic cavities and weak osteopontin expression within the bone matrix. Whereas, Fosamax, Vitamin K2, and fennel essential oil revealed obvious improvement in the histological changes depicted previously. Conclusion: Combined administration of fennel essential oil and Vitamin K2 has a more pronounced enhancing healing effect in PMO than Vitamin K2, fennel separately, or Fosamax. This could be attributed to the synergistic antioxidant and antiinflammatory properties in addition to the potent estrogenic effect of fennel. [ABSTRACT FROM AUTHOR]

The prevalence of metabolic syndrome (MetS) has been rising alarmingly and it has now become a global concern causing an enormous economic burden on the health care system. MetS is generally linked to complications in lipid metabolism, oxidative stress and low grade inflammation. The aim of the current study was to evaluate the effect of rosuvastatin, co-enzyme Q10 (CoQ10), and their combination on blood pressure, blood sugar, dyslipidemia, and liver function in rats with MetS induced by high fructose and high fat diet (HF-HFD) and the possible underlying mechanism. Oral administration of rosuvastatin (10 mg/kg/day), CoQ10 (10 mg/kg/day) and their combination for 4 weeks in HF-HFD-fed rats elevated serum high density lipoprotein and reduced glutathione. On the other hand, treatment with rosuvastatin, CoQ10 or their combination decreased the serum levels of malondialdehyde, triglycerides, total cholesterol, and low density lipoprotein-cholesterol as well as systolic blood pressure, body weight and fasting blood glucose level. In addition, the drugs or their combination declined serum pro-inflammatory cytokines, namely tumor necrosis factor-α and interleukin-1β. In conclusion, our results showed that rosuvastatin or CoQ10 protected against HF-HFD-induced MetS through the regulation of dyslipidemia, elevated blood glucose, elevated blood pressure, antioxidant defenses and inflammatory response. Rosuvastatin or CoQ10 also alleviated the impairment of liver function that was induced by HF-HFD. Interestingly, CoQ10 augmented rosuvastatin's effect in ameliorating MetS, via exerting synergistic modulatory effects on oxidative stress and inflammation. Thus, rosuvastatin and CoQ10 combination therapy may have possible applications in ameliorating metabolic disorders.

Urinary biomarkers such as neutrophil gelatinase-associated lipocalin (NGAL) and renalase were recently studied for their potential role in the early detection of acute kidney injury (AKI) in patients with cirrhosis. Our study was conducted on 50 patients with end-stage liver disease undergoing living donor liver transplantation. The patients were divided into two groups: Group I contained 23 patients with AKI who had undergone liver transplantation and Group II included 27 non-AKI patients who had undergone liver transplantation. Serum renalase and NGAL levels were measured by ELISA; renalase was measured on day 1, day 7, and three months after liver transplantation. NGAL was measured on day 1 postliver transplantation. There was an improvement in liver function, kidney functions, hemoglobin level, platelet count, and C- reactive protein levels in patients at three months posttransplantation when compared to day 1, day 3, and day 7 (P < 0.01). Comparison of the renalase level at day 1, day 7, and three months showed that there was a highly significant decline at three months in the AKI group compared to the non-AKI group (P < 0.01). Regarding the NGAL level at day 1, there was no significant difference between the AKI and non-AKI groups (P > 0.05). The receiver operating characteristic curve for the renalase biomarker showed a borderline significant change between the AKI and non-AKI groups at day 1 [area under the curve (AUC): 0.54, P = 0.08], day 7 (AUC: 0.605, P = 0.08), and three months (AUC: 0.605, P = 0.08). However, the NGAL biomarker level was not significantly different between the AKI and non-AKI groups. Our study suggests that renalase showed a better predictive value and a higher accuracy in identifying postliver transplantation patients with AKI than NGAL.

Novel complexes of Ru (III), Cu (II) and Au (III) (2–4) were prepared using 6-phenyl-2-thioxo-4-(trifluoromethyl)-1,2-dihydropyridine-3-carbonitrile (HL, 1) adopting either electrochemical or traditional chemical methods. The electrochemical method is preferred in the synthesis of the complexes than the chemical one because it affords pure products with higher yields in shorter reaction time. The novel thiopyridine complexes were characterized by elemental analyses, IR, 1H, 19F-NMR, TGA and DTA measurements. The antimicrobial activity evaluation revealed that the complex bearing copper metal 3 has nearly the same activity as the reference drug ciprofloxacin. Anti-inflammatory activity evaluation showed that complex 4 containing gold displayed anti-inflammatory activity higher than the reference drug celecoxib upon using carrageenan rat hind paw edema method.

Featured Application: Our study's findings offer significant practical implications for weather forecasting, climate research, and atmospheric modeling. Through the evaluation of Radio Occultation (RO) observations from the PlanetiQ mission and their comparison with existing datasets, we contribute to enhancing the accuracy of atmospheric profiling, benefiting weather forecasts, climate projections, and environmental monitoring. With PlanetiQ's groundbreaking GNOMES constellation, equipped with state-of-the-art "Pyxis" RO sensors, poised to collect over 50,000 soundings per day, this technological advancement promises to revolutionize global atmospheric monitoring, weather forecasting, space weather prediction, and climate analytics. Radio Occultation (RO) is pivotal for profiling the neutral and ionized atmosphere, with the PlanetiQ mission, via its GNOMES satellites, striving to establish an advanced atmospheric observing system.
