Computational-driven discovery of AI-2 quorum sensing inhibitor targeting the 5'- methylthioadenosine/S-adenosylhomocysteine nucleosidase (MTAN) to combat drug-resistant Helicobacter pylori.

MTAN is an attainable therapeutic target for H. pylori because it may minimize virulence production, limit resistance, and impair quorum sensing without affecting gut flora. Here, 457 compounds with anti-H.

Can switching from cigarettes to heated tobacco products reduce consequences of pulmonary infection?

Rationale: While tobacco industry data suggests that switching from combustible cigarettes to heated tobacco products (HTPs), like IQOS, may reduce the users' exposure to respiratory toxicants, it is not known if using HTPs impacts the outcomes of acute respiratory infections.

Objectives: Does switching from cigarettes to HTPs improve responses to pulmonary infection.

Methods: We conducted experiments in which 3 groups of mice were pre-exposed to cigarette smoke for 8 weeks, followed by 8-week exposure to (1) HTPs (tobacco product switching), (2) air (smoking cessation), or (3) continued exposure to cigarette smoke.

Effect of 1-MCP and KMnO4 treatments with different packaging on quality preservation of golden delicious apples.

This study explored the impact of three packaging materials (wooden boxes, corrugated fiber boxes, shrink-wrapped boxes) combined with two ethylene scrubbers (1-MCP, KMnO) on the shelf life of Golden Delicious apples. While previous research has extensively studied the effects of packaging and ethylene inhibitors independently, the novelty of this work lies in its combined evaluation of these factors under ambient storage conditions over an extended period of 160 days. The study specifically addresses a research gap by directly comparing the efficacy of 1-MCP and KMnO within different packaging environments, offering insights into their combined influence on key quality parameters such as firmness, juice yield, rot incidence, physiological loss in weight (PLW), acidity, and total soluble solids (TSS).

Exploring the Association of Biochemical Characterization and Genetic Determinants of TNF-α, CXCR2, and CCR5 Delta 32 Mutation with Predisposition to Polycystic Ovary Syndrome.

Unlabelled: PCOS is a heterogeneous, multifactorial endocrine disorder with a complex pathophysiology. It is a globally rising infertility disorder that affects a large percentage of women of reproductive age, with a relatively high prevalence of 8-13%. Genome-wide association studies have revealed associations of genetic variations with many diseases, including PCOS.
