Knowledge, attitude and practice towards physical activity among healthcare students at a public university in Saudi Arabia.

Objective: This research aimed to study the knowledge, attitudes, and practices (KAP) toward physical activity (PA) of healthcare students at King Khalid University in Abha, Saudi Arabia.

Methods: A prospective web-based cross-sectional study was carried out among healthcare students of King Khalid University from March to May 2024. The questionnaire contained questions on sociodemographic details, five questions about knowledge, eight questions about attitudes, and seven practice-related questions.

An evaluation of knee osteoarthritis pain in the general community-Asir region, Saudi Arabia.

Background: Knee osteoarthritis (KOA) is one of the most common conditions resulting in disability, particularly in the elderly population. Osteoarthritis (OA) is the most common articular disease and the leading cause of chronic disability in the developed world.

Objective: This study was carried out to evaluate knee pain in the Asir region of Saudi Arabia.

Spontaneous Isolated Inferior Mesenteric Artery Dissection With Chronic Mesenteric Ischemia: Case Report and Endovascular Management.

We report the clinical details, imaging findings, and management for a 39-year-old female presenting with recurrent episodes of pain in abdomen due to systemic lupus erythematous vasculitis associated with spontaneous isolated inferior mesenteric dissection. Spontaneous mesenteric artery dissection is an uncommon cause of mesenteric ischemia. Symptomatic spontaneous isolated inferior mesenteric artery (IMA) dissection is a rare condition, and its association with systemic lupus erythematosus is not previously described in the English literature.

Exploring current status of Helicobacter pylori infection in different age groups of patients with dyspepsia.

Recent data from Asian countries including India has shown a significant decline in the frequency of peptic ulcer disease (PUD) compared to the past. H. pylori is considered the most important risk factor for PUD, and we aimed to explore the current frequency of H.

Endoscopic ultrasonography in pediatric patients--Experience from a tertiary care center in India.

Background And Aims: Although endoscopic ultrasound (EUS) is used in the management of various gastrointestinal (GI) diseases in adults, data on its role in children is limited. This study evaluated the indications, safety, and impact of EUS in children.

Methods: Records of children (<18 years age) who underwent EUS between January 2006 and September 2014 were reviewed retrospectively and analyzed.

Effect of carbon source on enzymes involved in glycerol metabolism in Neurospora crassa.

Specific activities of eight enzymes involved in glycerol metabolism were determined in crude extracts of three strains of Neurospora crassa after growth on six different carbon sources. One of the strains was wild type, which grew poorly on glycerol as sole carbon source; the other two were mutant strains which were efficient glycerol utilizers. A possible basis for this greater efficiency of glycerol utilization was catabolite repression of glyceraldehyde kinase by glycerol in wild type, and two-fold higher glycerate kinase activity in the mutant strains after growth on glycerol, thus apparently allowing two routes for glyceraldehyde to enter the glycolytic pathway in the mutant strains but only one in wild type.

Characterization of glycerol nonutilizing and protoperithecial mutants of Neurospora.

Mutants defective in polyol metabolism and/or in protoperithecial development were selected in Neurospora tetrasperma, a species in which protoperithecial development occurs at nonpermissively high temperature if certain polyols are used in lieu of sucrose as carbon source. Mutants selected for nonutilization of one of the four polyols tested, glycerol, mannitol, sorbitol, or xylitol, were usually found to be nonutilizers of the other three polyols as well. Mutants blocked at various stages of protoperithecial development complemented pairwise to produce more advanced developmental stages, usually mature protoperithecia and, when of opposite mating type, mature perithecia.
