  • * A study involving 45 ESRD patients found a higher prevalence of CMV-IgG (42.2%) compared to a control group (22.2%), but similar levels of CMV-IgM between the two groups.
  • * CMV seropositivity is linked to a higher rate of anemia in ESRD patients (77.3% in seropositive vs 47.8% in seronegative), highlighting the importance of early detection and monitoring of CMV to improve patient outcomes

Several single nucleotide polymorphisms (SNPs) in multiple interleukin receptor genes could be associated with asthma risk and/or phenotype. Interleukin-17 (IL-17) has been implicated in tissue inflammation and autoimmune diseases. As no previous studies have uncovered the potential role of () gene variants in asthma risk, we aimed to explore the association of four SNPs (i.

After the COVID-19 pandemic, there was an increasing demand for remote learning and an expansion in the substitution of traditional practical sessions with lab-based virtual tools. This study aimed to assess the effectiveness of virtual labs in practicing biochemical experiments and to examine the student's feedback regarding this tool. Virtual and traditional labs training were compared in teaching qualitative analysis of proteins and carbohydrates experiments for first-year medical students.

Background And Study Aim: Failure of optimal growth and lack of appropriate weight gain are major nutritional problems in children with inflammatory bowel disease (IBD). Therefore, this study was designed to assess the nutritional and growth status of patients with very-early-onset IBD (VEO-IBD) before and after individual-based nutritional interventions.

Patients And Methods: This prospective cohort study assessed the nutritional status of 30 pediatric patients with VEO-IBD by performing comprehensive clinical examinations and evaluating anthropometric and biochemical parameters.

Inherited retinal dystrophies are caused by mutations in more than 250 genes, each of them carrying several types of mutations that can lead to different clinical phenotypes. Mutations in () cause X-linked Retinitis pigmentosa (RP). A nucleotide substitution in intron 9 of causes the increase of an alternatively spliced isoform of the mature mRNA, bearing exon 9a (E9a).

Consistency and duplicability in Computed Tomography (CT) output is essential to quantitative imaging for lung cancer detection and monitoring. This study of CT-detected lung nodules investigated the reproducibility of volume-, density-, and texture-based features (outcome variables) over routine ranges of radiation dose, reconstruction kernel, and slice thickness. CT raw data of 23 nodules were reconstructed using 320 acquisition/reconstruction conditions (combinations of 4 doses, 10 kernels, and 8 thicknesses).

Background: Several biomarkers of gemcitabine effectiveness have been studied in cancers, but less so in hepatocellular carcinoma (HCC), which is identified as the fifth most common cancer worldwide. Investigation of human equilibrative nucleoside transporter-1 (HENT-1) and deoxycytidine kinase (DCK), genes involved in gemcitabine uptake and metabolism, can be beneficial in the selection of potential cancer patients who could be responding to the treatment.

Aim: To study HENT-1 and DCK gene expression in HCC patients with different protocols of treatment.

Background: Simulation-based learning (SBL), an effective teaching strategy, is still questionable on whether it can be an alternative to didactic lectures in medical education. Our study aimed to evaluate the effectiveness of SBL versus traditional lectures in retention of knowledge.

Methods: A randomized controlled trial was conducted among medical students who were divided in two groups (36 students each).

Obesity is a public health burden disturbing all body functions and reproductive hormones. As obesity increases among females, there will be a rising challenge to physicians in care from fertility problems. Evening primrose oil (EPR oil) contains essential fatty acids including omega-6 linoleic acid with strong anti-inflammatory activity.

Aims: Hypercholesterolemia is a hazard for increasing susceptibility of the heart to myocardial infarction (MI) by inducing platelet hyperaggregability. Clopidogrel and prasugrel have documented cardioprotective effects in clinical studies. Herein, we investigated whether clopidogrel and prasugrel could protect against isoproterenol-induced acute MI (A-MI) under hypercholesterolemic conditions in rats.

Background: The relation between grand multiparity (GMP) and the possible adverse pregnancy outcomes is not well identified. GMP (parity ≥5 births) frequently occurs in the Arab nations; therefore, this study aimed to identify the correlation between GMP and the different adverse maternal and neonatal outcomes in the Saudi population.

Method: This cohort study was conducted on a total of 3327 women from the labour ward in King Khaled University Hospital, Riyadh, Saudi Arabia.

Purpose: To compare the hip morphology of adolescent male patients and female patients who underwent hip arthroscopy for femoroacetabular impingement (FAI) and determine if gender differences exist.

Methods: We retrospectively reviewed the records of 177 adolescents, aged 13 to 18 years, who were treated for FAI with hip arthroscopy. We examined and analyzed preoperative magnetic resonance imaging (MRI) scans and plain radiographs, measuring the lateral center-edge angle, Tönnis angle, and alpha angle.

Hepatocellular carcinoma (HCC) incidence is fast-growing especially in countries highly prevalent with viral hepatitis. Its poor prognosis has driven the research toward the discovery of sensitive markers for early detection. We investigated the usefulness of serum Transforming growth factor-beta1 (TGF-β1), Glypican-3 (GPC3), and Golgi protein-73 (GP73) mRNAs as early biomarkers in HCC Egyptian patients chronically infected with hepatitis C virus (HCV) in comparison with serum alpha-fetoprotein (AFP).

Background: Allergic diseases, such as allergic rhinitis (AR) and atopic dermatitis (AD), affect a large proportion of people worldwide. Both have environmental and genetic predisposing factors. Single nucleotide polymorphisms (SNPs) in interleukin (IL)-18, may play a direct role in the disease pathogenesis.

The present study was initiated to elucidate the effect of potato tubers treatment using fine dusts of Psidium guajava, Cymbopogon citratus, talc powder and their progressive dilutions(w/w) on the fitness components of raised generations of the potato tuber moth (PTM), Phthorimaea operculella. Results showed a direct as well as cumulative delayed effect of the tested plants fine dusts, either alone or admixed with talc powder in progressive dilutions from 5% up to 50% w/w on the viability of developing immatures and potentiality of adult moths. The revealed effects of each of the tested crude plant fine dusts or talc powder alone and/or their progressive dilutions (w/w) could be explained briefly as gradual significant shortening of life span of both sexes, prolongation of larval duration, reduction in number of raised pupae, increase of malformed ones, sharp decrease in the rate of emerged moths, deposited eggs, and developing of immatures; According to lower used dilutions of each tested plant fine dust from 5% to 20%, the complete inhibition of reproductive potential of both adult sexes, the going on metamorphic development of deposited eggs and/or raised immatures of the following generation, after the treatment of parent one, had been revealed the following distinct failure of: a) F1 development after former treatment of parent generation with the higher concentrations of 30-50% of both tested plant fine dusts and the lower prepared dilutions (10% and 20% (w/w)) of both the tested Psidium guajava and (20% (w/w)) Cymbopogom citratus plant fine dusts, resulted in fewer number of the emerged moths that were unviable, weak, sterile and died before induction the F1 progeny, b) F2 development due to the former treatment of the parents with talc powder, Psidium guajava fine dusts alone or its prepared dilutions of (5% (w/w)) and Cymbopogom citratus dilution of (10%(w/w)) gave unviable weak and sterile moths unable to induce the F2 progeny, c) F3 development post former treatment of the parent generations with Cymbopogom citratus dilution of 5% (w/w) induced unviable sterile moths and died after emergence and d) F4 development owing to the former parent treatment with Cymbopogon citratus fine dust alone; The complete failure of each of the above mentioned generations could be attributed to the cumulative effect of induced recessive lethal genes in both sexes along the extended period of each of these following generations, post former treatment of parent one, causing apparent undesirable effects, that appeared at the beginning of each of them.
