Cognitive Enhancers Consumption: Prevalence, Knowledge, and Determinants of Use Among Medical Students in Egypt, Sudan, and Jordan.

Background: Cognitive Enhancers (CE) are central nervous system stimulant substances known to improve cognitive functions. Due to high-perceived stress and academic pressure, CEs are becoming increasingly popular among medical students. As a result, they are more likely to misuse these substances.

The Effects of Different Nursing Positions During Preterm Infants Feeding on Gastric Residual Volume and Emptying Rate: A Systematic Review and Network Meta-Analysis.

Background And Objectives: Preterm infants need nutritional support due to their premature digestive system, undeveloped anatomy and functional limitations. Neonatal positioning in the proper position is one of the nurses' main principles that affect the residual volume. We performed our systematic review and network meta-analysis to determine the best feeding position for preterm infants in reducing gastric residual volume and increasing the rate of gastric emptying.

Risk Factors of Rheumatic Heart Disease in a Children's Hospital in Khartoum: A Case-Control Study.

Background: Rheumatic heart disease (RHD) is the most prevalent acquired cardiac illness in Sudan, arising as a complication of acute rheumatic fever (ARF). Additionally, Sudan exhibited a wide diversity in the distribution of RHD. The echocardiographic screening revealed 3/1000 cases in one region (Khartoum), while in another region (Nort Kordofan), it revealed 61/1000 cases.

Pan-Cancer Analysis Reveals Long Non-coding RNA (lncRNA) Embryonic Stem Cell-Related Gene (ESRG) as a Promising Diagnostic and Prognostic Biomarker.

Background: Embryonic stem cell-related gene (ESRG; also known as HESRG) is a long non-coding RNA (lncRNA). It is involved in the regulation of human pluripotent stem cells (hPSCs) self-renewal. ESRG gene has the ability to interact with chromatins, different RNA types, and RNA binding proteins (RBP); thus making ESRG be considered an oncogenic lncRNA, where its expression is detected in various tumor tissues.

Defending the right to health in Gaza: a call to action by health workers.

The ongoing conflict in Gaza has led to severe destruction of the health system and eventually its collapse. Moreover, multiple attacks on health workers were reported which led to obstacles in service delivery. The conflict has led to further humanitarian crises including shortage of food, water sanitation, and hygiene, and outbreaks of infectious diseases.

Patients And Methods: A cross-sectional, retrospective study design was used to recruit all patients aged > 18 years who were diagnosed with or suspected of having bacterial meningitis and admitted to Wad Medani Teaching Hospital, Gezira State, Sudan, between January 2017 and October 2022.

Results: In total, 201 patients were included in the analysis.

Kupffer cells dictate hepatic responses to the atherogenic dyslipidemic insult.

Apolipoprotein-B (APOB)-containing lipoproteins cause atherosclerosis. Whether the vasculature is the initially responding site or if atherogenic dyslipidemia affects other organs simultaneously is unknown. Here we show that the liver responds to a dyslipidemic insult based on inducible models of familial hypercholesterolemia and APOB tracing.

Effectiveness of full Pulpotomy compared with Root canal treatment in managing teeth with signs and symptOms indicative of irreversible pulpitis: a protocol for prospectiVE meta-analysis of individual participant data of linked randomised clinical trials (PROVE).

Background: Full pulpotomy has been proposed as an alternative to root canal treatment in teeth with signs and symptoms indicative of irreversible pulpitis (IRP), but the evidence is limited, relying on underpowered studies with a high risk of bias. The aim of this study is to conduct a prospective meta-analysis (PMA) of individual participant data of a series of individual randomised trials to provide robust evidence on the clinical and cost-effectiveness of pulpotomy compared with root canal treatment.

Methods: Individual participant data will be obtained from a series of randomised trials designed and conducted by a consortium of multi-national investigators with an interest in vital pulp treatment.

Expanding the therapeutic arsenal against cancer: a computational investigation of hybrid xanthone derivatives as selective Topoisomerase 2α ATPase inhibitors.

The DNA topoisomerase II (topo II) enzyme plays an important role in the replication, recombination, and repair of DNA. Despite their widespread applications in cancer therapy, new, selective, and potent topo II inhibitors with better pharmaceutical profiles are needed to handle drug resistance and severe adverse effects. In this respect, an array of 36 new anticancer compounds was designed based on a Xanthone core tethered to multifunctional Pyridine-amines and Imidazole scaffold alkyl chain linkers.

Genetic variation for grain nutritional profile and yield potential in sorghum and the possibility of selection for drought tolerance under irrigated conditions.

Background: Increasing grain nutritional value in sorghum (Sorghum bicolor) is a paramount breeding objective, as is increasing drought resistance (DR), because sorghum is grown mainly in drought-prone areas. The genetic basis of grain nutritional traits remains largely unknown. Marker-assisted selection using significant loci identified through genome-wide association study (GWAS) shows potential for selecting desirable traits in crops.

Glucagon-like peptide-1 receptor-agonists treatment for cardio-metabolic parameters in schizophrenia patients: a systematic review and meta-analysis.

Aims: We performed this meta-analysis to evaluate the efficacy and safety of glucagon-like peptide-1 receptor-agonists (GLP-1RA) treatment on cardio-metabolic parameters among antipsychotic-treated patients with schizophrenia.

Methods: We searched the Web of Science, Cochrane Central Register of Controlled Trials, PubMed, PsycINFO, and Scopus for relevant Randomized Clinical trials (RCTs) from inception until 1 August 2022. Documents were screened for qualified articles, and all concerned outcomes were pooled as risk ratios (RR) or mean difference (MD) in the meta-analysis models using Review Manager (RevMan version 5.

Hepatic stellate cell activation markers are regulated by the vagus nerve in systemic inflammation.

Background: The liver is an important immunological organ and liver inflammation is part of the pathophysiology of non-alcoholic steatohepatitis, a condition that may promote cirrhosis, liver cancer, liver failure, and cardiovascular disease. Despite dense innervation of the liver parenchyma, little is known about neural regulation of liver function in inflammation. Here, we study vagus nerve control of the liver response to acute inflammation.

Fabrication of a Novel CNT-COO/AgPO@AgIOComposite with Enhanced Photocatalytic Activity under Natural Sunlight.

In this study, a carboxylated carbon nanotube-grafted AgPO@AgIO (CNT-COO/AgPO@AgIO) composite was synthesized through an in situ electrostatic deposition method. The synthesized composite was characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), and energy-dispersive X-ray spectroscopy (EDS). The electron transfer ability of the synthesized composite was studied using electrochemical impedance spectroscopy (EIS).

QTRAP LC/MS/MS of Garlic Nanoparticles and Improving Sunflower Oil Stabilization during Accelerated Shelf Life Storage.

The purpose of this research was to assess and utilize the bioactive compounds of garlic nanoparticles (Ga-NPs) as a natural antioxidant in sunflower oil (SFO) stored at 65 ± 1 °C for 24 days. The garlic nanoparticles (Ga-NPs) from the Balady cultivar were prepared, characterized, and added to SFO at three concentrations: 200, 600, and 1000 ppm (/), and they were compared with 600 ppm garlic lyophilized powder extract (Ga-LPE), 200 ppm BHT, 200 ppm α-tocopherol, and SFO without Ga-NPs (control). The QTRAP LC/MS/MS profile of Ga-NPs revealed the presence of four organosulfur compounds.

The Spike Protein of SARS-coV2 19B (S) Clade Mirrors Critical Features of Viral Adaptation and Coevolution.

Pathogens including viruses evolve in tandem with diversity in their animal and human hosts. For , the focus is generally for understanding such coevolution on the virus spike protein, since it demonstrates high mutation rates compared to other genome regions, particularly in the receptor-binding domain (RBD). Viral sequences of the 19B (S) clade and variants of concern from different continents were investigated, with a focus on the A.
