Unlocking a Decade of Research on Embryo-Derived Extracellular Vesicles: Discoveries Made and Paths Ahead.

Over the past decade, research on embryo-derived extracellular vesicles (EVs) has unveiled their critical roles in embryonic development and intercellular communication. EVs secreted by embryos are nanoscale lipid bilayer vesicles that carry bioactive cargo, including proteins, lipids, RNAs, and DNAs, reflecting the physiological state of the source cells. These vesicles facilitate paracrine and autocrine signaling, influencing key processes such as cell differentiation, embryo viability, and endometrial receptivity.

Investigation into Alzheimer's-related amyloid-β conformational transformations and stability influenced by green iron oxide nanoparticles (GIONP).

Alzheimer's disease (AD) is popularly believed to be triggered by the aggregation of amyloid beta 1-42 (Aβ - 42) peptides, eventually leading to neurodegeneration. Our study delves into the influential role played by Green Iron Oxide Nanoparticles (GIONP). GIONP are typically synthesized using a green chemistry approach, imposing curcumin as a biocompatible reducing and capping agent, leveraging its inherent antioxidant, anti-inflammatory, and neuroprotective attributes.

Oral supplementation of curcumin-encapsulated chitosan nanoconjugates as an innovative strategy for mitigating nickel-mediated hepatorenal toxicity in rats.

Alopecia Management Potential of Rosemary-Based Nanoemulgel Loaded with Metformin: Approach Combining Active Essential Oil and Repurposed Drug.

Introduction: Androgenetic alopecia (AGA) is a multifactorial and age-related dermatological disease that affects both males and females, usually at older ages. Traditional hair repair drugs exemplified by minoxidil have limitations such as skin irritation and hypertrichosis. Thus, attention has been shifted to the use of repurposing drugs.

The role of neutrophilia in hyperlactatemia, blood acidosis, impaired oxygen transport, and mortality outcome in critically ill COVID-19 patients.

Introduction: COVID-19 severity and high in-hospital mortality are often associated with severe hypoxemia, hyperlactatemia, and acidosis, yet the key players driving this association remain unclear. It is generally assumed that organ damage causes toxic acidosis, but since neutrophil numbers in severe COVID-19 can exceed 80% of the total circulating leukocytes, we asked if metabolic acidosis mediated by the glycolytic neutrophils is associated with lung damage and impaired oxygen delivery in critically ill patients.

Methods: Based on prospective mortality outcome, critically ill COVID-19 patients were divided into ICU- survivors and ICU-non-survivors.

Public's perception of policies reducing tobacco availability by regulating the tobacco retail environment: A case study in Egypt.

Introduction: The tobacco industry presence in the retail environment ensures its access to current and potential tobacco users. Reduction of tobacco retail is an emerging tobacco control measure. Many policies that would potentially lead to reduction in retail are not covered by international tobacco laws and are individually adopted in some jurisdictions.

The Impact of Idiopathic Intracranial Hypertension on Cardiovascular Disease Risk Among UK Women: An Obesity-Adjusted Analysis.

Introduction: Idiopathic intracranial hypertension (IIH) is known to elevate cardiovascular disease (CVD) risk, but the extent to which obesity and IIH-specific factors contribute to this risk is not well understood. WE aim to separate the effects of obesity from IIH-specific factors on the risk of stroke and CVD, building on previous findings that indicate a two-fold increase in cardiovascular events in women with IIH compared to BMI-matched controls.

Methods: An obesity-adjusted risk analysis was conducted using Indirect Standardization based on data from a cohort study by Adderley et al.

Experience, Outcomes, and Insights on Endoscopic Colonic Polyp Excision: A Retrospective Cohort Study.

Introduction Colorectal cancer (CRC) continues to pose a major public health challenge, ranking among the most common malignancies globally and being a leading cause of cancer-related mortality. Most CRCs originate from adenomatous polyps, underscoring the importance of detecting and removing these precancerous growths as a key preventive measure against CRC. In particular, large colonic polyps (≥10 mm) warrant special attention due to their increased risk of progressing to malignancy compared to smaller polyps.
