A Rare Case Report of the Successful Management of Perforated Sigmoid Volvulus in a Pregnant Woman With Massive Pneumoperitoneum: First Case in Yemen.

Sigmoid volvulus during pregnancy is an extremely rare condition that presents as intestinal obstruction and can lead to severe complications for both the mother and fetus if not promptly diagnosed and treated. To our knowledge, this is the first documented case in Yemen. We report a case of a 39-year-old pregnant woman at 32 weeks of gestation who presented with acute abdominal pain, constipation, and signs of peritonitis.

Knowledge, attitude, and practices of the community toward dengue fever in Shabwah Governorate, Yemen: a descriptive study.

Background: In Yemen, dengue fever (DF) is a widespread, locally endemic infectious disease, with high morbidity and mortality which mainly affects impoverished regions. Thus, this study aims to evaluate the knowledge, attitudes, and behaviors of the Shabwah community in Yemen regarding DF characteristics and prevention.

Methods: The present study is a cross-sectional community-based study conducted in Shabwah Governorate, Yemen, between June 2021 and November 2021.

Bariatric Surgery-Induced Cardiac and Lipidomic Changes in Obesity-Related Heart Failure with Preserved Ejection Fraction.

Objective: To determine the effects of gastric bypass on myocardial lipid deposition and function and the plasma lipidome in women with obesity and heart failure with preserved ejection fraction (HFpEF).

Methods: A primary cohort (N = 12) with HFpEF and obesity underwent echocardiography and magnetic resonance spectroscopy both before and 3 months and 6 months after bariatric surgery. Plasma lipidomic analysis was performed before surgery and 3 months after surgery in the primary cohort and were confirmed in a validation cohort (N = 22).

Antifungal Activity of Aqueous Extracts of Some Dominant Algerian Medicinal Plants.

Aim: This study investigated the antifungal properties of aqueous extracts obtained from indigenous plants that grow spontaneously in the Northern Sahara of Algeria. The activities of these plants in controlling two fungal species that belong to genus were evaluated in an in vitro assay.

Materials And Methods: Fresh aerial parts of four plant species (, and ) were collected for the preparation of aqueous extracts.

Influence of Extracting Solvent on Pharmacological Activity and Cytotoxicity of , a Commonly Consumed Herb in Southeast Asia.

Objective: To investigate the antihyperlipidemic, antioxidant, and cytotoxic effect of aqueous and methanol extract of leaves of .

Materials And Methods: Acute antihyperlipidemic effect was studied on chemically induced hyperlipidemic rat model. Treated groups received aqueous and methanol extract of leaves of respectively (1000 mg/kg; oral) whereas standard treated group received atorvastatin (60 mg/kg; oral) for 3 consecutive days.

Anti-angiogenic quassinoid-rich fraction from Eurycoma longifolia modulates endothelial cell function.

Targeting angiogenesis could be an excellent strategy to combat angiogenesis-dependent pathophysiological conditions such as cancer, rheumatoid arthritis, obesity, systemic lupus erythematosus, psoriasis, proliferative retinopathy and atherosclerosis. Recently a number of clinical investigations are being undertaken to assess the potential therapeutic application of various anti-angiogenic agents. Many of these angiogenesis inhibitors are directed against the functions of endothelial cells, which are considered as the building blocks of blood vessels.

Optimization of the storage conditions for coagulation screening tests.

Objective: To determine the optimum storage temperature and time for prothrombin time and activated partial thromboplastin time at various intervals at both room temperature and refrigerator.

Study Design: Experimental study.

Place And Duration Of Study: Advanced Medical and Dental Institute (AMDI), Laboratory at University Sains Malaysia (USM), from August 2009 to June 2010.

Effects of phosphodiesterase type 5 inhibition on systemic and pulmonary hemodynamics and ventricular function in patients with severe symptomatic aortic stenosis.

Background: Pressure overload resulting from aortic stenosis causes maladaptive ventricular and vascular remodeling that can lead to pulmonary hypertension, heart failure symptoms, and adverse outcomes. Retarding or reversing this maladaptive remodeling and its unfavorable hemodynamic consequences has the potential to improve morbidity and mortality. Preclinical models of pressure overload have shown that phosphodiesterase type 5 inhibition is beneficial; however, the use of phosphodiesterase type 5 inhibitors in patients with aortic stenosis is controversial because of concerns about vasodilation and hypotension.

Exercise echocardiography in rheumatoid arthritis: a case-control study.

Background: Rheumatoid arthritis (RA) is associated with increased cardiovascular risk.

Methods: To assess the role of exercise echocardiography (EE) in the evaluation of patients with RA, follow-up (mean, 6.7+/-3.

Strain rate imaging differentiates hypertensive cardiac hypertrophy from physiologic cardiac hypertrophy (athlete's heart).

Background: This study sought to determine whether strain rate imaging could distinguish between individuals with hypertensive left ventricular hypertrophy (LVH) and those with strength-training athletic LVH.

Methods: In all, 108 participants (30 hypertensive LVH, 30 strength-training LVH, 48 control) were enrolled. In addition to a baseline echocardiogram, strain, peak systolic strain rate (SR(S)), peak early diastolic strain rate (SR(E)), and peak late diastolic strain rate values were compared in the apical 4-chamber view.

Developmental changes in the orexin 2 receptor mRNA in hypoglossal motoneurons.

Hypothalamic orexin-containing neurons project to many CNS targets, including motoneurons. We assessed developmental changes in the expression of the orexin type 2 receptor (ORX2r) mRNA in hypoglossal (XII) motoneurons. Identified motoneurons were dissociated from 4- to 33-day-old rats and subjected to single-cell reverse transcription and PCR; nearly all contained the ORX2r mRNA.
