Co-culture of Helicobacter pylori with oral microorganisms in human saliva.

Objective: Helicobacter pylori is known for colonizing the gastric mucosa and instigating severe upper gastrointestinal diseases such as gastritis, gastroduodenal ulcers, and gastric cancer. To date, there is no data available on the oral cavity as transmission site, whether H. pylori can survive in the oral cavity or in human saliva.

Results of ICE-Guided Isolation of the Superior Vena Cava With Pulsed Field Ablation.

Background: Earlier studies have documented the risk for sinoatrial node injury and phrenic nerve paralysis as complications following radiofrequency catheter ablation for electrical isolation of the superior vena cava (SVCI).

Objectives: The aim of this study was to assess the safety and feasibility of SVCI in patients with atrial fibrillation undergoing pulsed field ablation (PFA) METHODS: Six hundred sixteen consecutive patients undergoing PFA for pulmonary vein isolation plus SVCI were included in this multicenter analysis. Superior vena cava (SVC) ablation was performed under the continuous guidance of intracardiac echocardiography.

Determinants of school-going adolescent girls' health and nutritional status in district Malir, Karachi: a baseline cross-sectional study.

Introduction: Adolescence is a phase of life marked by rapid growth. Adequate nutrition is essential during this developmental stage, leading to significant physical performance, improved cognitive ability, and productivity. Improving adolescent girls' nutrition is crucial for breaking the intergenerational cycle of malnutrition, but research in Pakistan has largely focused on children under five and pregnant women, often neglecting this vulnerable group.

Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches.

Micro-and-nano plastics (MNPs) are pervasive in terrestrial ecosystems and represent an increasing threat to plant health; however, the mechanisms underlying their phytotoxicity remain inadequately understood. MNPs can infiltrate plants through roots or leaves, causing a range of toxic effects, including inhibiting water and nutrient uptake, reducing seed germination rates, and impeding photosynthesis, resulting in oxidative damage within the plant system. The effects of MNPs are complex and influenced by various factors including size, shape, functional groups, and concentration.

Thymoquinone Mediates Müller Cell Apoptosis via miR-29b/SP1 Pathway: A Potential Therapeutic Approach in Diabetic Retinopathy.

This study aims to explore the therapeutic potential of thymoquinone (TQ) in DR by assessing its effects on Müller cell apoptosis through modulation of the miR-29b/SP1 pathway in a diabetic animal model.Healthy C57BL/6 mice (25 g) were used in the study. Retinal samples were collected from both normal and diabetic mice subjected to various treatments: TQ (1 mg/kg/day), glibenclamide (GLB, 250 mg/kg/day), sitagliptin (STG, 10 mg/kg/day), and metformin (MET, 5 mg/kg/day) over a period of 28 days.
