Dual Inhibition of sEH and COX-2 Improved Cognition in Alzheimer's Disease via Enhanced Myogenic Response and Cerebral Artery Distensibility.

Genetic studies have linked (encoding soluble epoxide hydrolase, sEH) and (encoding cyclooxygenase-2, COX-2) to Alzheimer's disease (AD). Elevated levels of sEH and COX-2 found in AD patients and animals suggest their involvement in neurodegeneration, glial activation, vascular dysfunction, and inflammation. This study evaluated the effects of a new dual sEH/COX-2 inhibitor, PTUPB, on cerebrovascular function and cognition in TgF344-AD rats.

Clinical Implications of heavy silicon oil (Densiron®) endotamponade after pars plana vitrectomy: A systematic review and meta-analysis.

Rhegmatogenous retinal detachments (RRDs) with inferior retinal breaks (IRBs) pose significant surgical challenges, lacking a universally accepted treatment standard. Heavy silicone oils (HSOs), specifically Densiron® 68 and Densiron XTRA, have emerged as promising endotamponade agents because of their specific gravity, which is greater than that of water, allowing effective tamponade in the inferior retina. Unlike earlier HSO formulations, these newer variants show reduced rates of intraocular inflammation while maintaining favorable anatomical outcomes, even when compared with concomitant scleral buckle (SB) use; however, their usage remains limited, particularly in the U.

Lung Transcriptomics Links Emphysema to Barrier Dysfunction and Macrophage Subpopulations.

Rationale: While many studies have examined gene expression in lung tissue, the gene regulatory processes underlying emphysema are still not well understood. Finding efficient non-imaging screening methods and disease-modifying therapies has been challenging, but knowledge of the transcriptomic features of emphysema may help in this effort.

Objectives: Our goals were to identify emphysema-associated biological pathways through transcriptomic analysis of bulk lung tissue, to determine the lung cell types in which these emphysema-associated pathways are altered, and to detect unique and overlapping transcriptomic signatures in blood and lung samples.

Horizontal Chemistry.

In 1976 Raymond Williams commented, 'Culture is one of the two or three most complicated words in the English language.' Such implied difficulty has not prevented Bloomsbury Academic, since the 2000s, from publishing around forty series of their well-produced and generously illustrated Cultural Histories, with, according to their website, a further fifty in progress. Each series contains six volumes, each book covering, in theory, the same chronological period (antiquity, the Middle Ages, the Renaissance, the Enlightenment, the age of empire and the modern age), though there is some variation depending on precise topic.

An Introduction to the Native and Non-Native Plant-Insect Interactions and Potential Pollinators of Puerto Williams and Yendegaia, Cabo de Hornos, Chile.

The Magellanic sub-Antarctic ecoregion of southern Chile represents one of the last remaining pristine areas on Earth, but there are knowledge gaps concerning the biodiversity and interactions of the regions' flora and fauna. Non-native insect species like and are known to have detrimental influence on native populations through competition for resources/nesting habitat, larvae predation, and foreign pathogen introduction. However, their interactions with the native and non-native plants in the region and between introduced species are unknown.
