Methanol electro oxidation on Ni-Pt-CrO/CNFs composite: morphology, structural, and electrochemical characterization.

In this work, prepared nanoparticle samples of NiCr with a fixed ratio of platinum (3%) were synthesized and loaded onto carbon nanofibers, which were produced by an electrospinning technique and carbonized at 900 °C for 7 h in an argon atmosphere. A variety of analysis techniques were applied to examine the stoichiometry, structure, surface morphology, and electrochemical activity. The carbonization process produces carbon nanofibers decorated with metal nanoparticles.

Effects of adherence to the Mediterranean diet in children and adolescents with irritable bowel syndrome.

Background: Irritable bowel syndrome (IBS) is a highly prevalent gastrointestinal disorder in children and adults, which increased over the past twenty years. The Mediterranean diet is a well-known diet full of antioxidants and anti-inflammatory ingredients.

Aim: To evaluate the safety, tolerability, and effects of adherence to the Mediterranean diet on disease patterns in children and adolescents with IBS.

Health Risk Assessment of Exposure to Heavy Metals from Sheep Meat and Offal in Kuwait.

Abstract: A total of 600 sheep samples (200 each of muscle, liver, and kidney) collected from 200 sheep carcasses slaughtered at abattoirs in Kuwait were analyzed by atomic absorption spectrophotometry for concentrations of mercury (Hg), arsenic (As), lead (Pb), cadmium (Cd), and chromium (Cr). These metals were detected in all (100%) examined samples; higher concentrations occurred in kidney followed by liver and muscle. The mean (±standard error of the mean) values of the metals detected in sheep muscle, liver, and kidney samples were 0.

Heavy Metal Residues in Some Fishes from Manzala Lake, Egypt, and Their Health-Risk Assessment.

A total of 600 freshly caught fish samples (200 each of Nile tilapia, flathead grey mullet, and African catfish) were collected from Manzala Lake, Egypt, and analyzed for determination of heavy metal residues using an atomic absorption spectrophotometer. Metal concentrations (µg/g wet weight) were detected in all examined samples in quantities of 0.045, 0.

Prevalence and antimicrobial resistance pattern of bacterial strains isolated from patients with urinary tract infection in Messalata Central Hospital, Libya.

Objectives: To investigate the prevalence of urinary tract infection among patients at Messalata Central Hospital, Libya, to identify the causative bacteria, and to explore their resistance pattern to antimicrobials.

Methods: A total number of 1153 urine samples were collected from patients, who attended daily to Messalata Central Hospital, Libya, in a study extended for one year. Antimicrobial susceptibility testing and isolates typing were done using Phoenix BD (BD diagnostic).

Prevalence, genetic characterization and virulence genes of sorbitol-fermenting Escherichia coli O157:H- and E. coli O157:H7 isolated from retail beef.

Sorbitol-fermenting (SF) Escherichia coli O157:H- strains have emerged as important pathogens and have been associated with a higher incidence of progression to hemolytic-uremic syndrome (HUS) than non-sorbitol fermenting (NSF) E. coli O157:H7. The present study was carried out to determine the prevalence of SF E.

Relationship between endothelial cell loss and microcoaxial phacoemulsification parameters in noncomplicated cataract surgery.

Purpose: To assess the relationship between postoperative endothelial cell loss and microcoaxial phaco parameters using Ozil IP (Alcon Laboratories, Inc, Fort Worth, TX) in noncomplicated cataract surgery.

Methods: In this prospective observational study, 120 consecutive cases of cataract patients with different grades of nuclear hardness underwent microcoaxial phacoemulsification through a 2.2-mm clear corneal incision.
