Coupling of response biomarkers between tumor and peripheral blood in patients undergoing chemoimmunotherapy.

Platinum-based chemotherapy in combination with anti-PD-L1 antibodies has shown promising results in mesothelioma. However, the immunological mechanisms underlying its efficacy are not well understood and there are no predictive biomarkers to guide treatment decisions. Here, we combine time course RNA sequencing (RNA-seq) of peripheral blood mononuclear cells with pre-treatment tumor transcriptome data from the single-arm, phase 2 DREAM trial (N = 54).

An integrated approach to coupled nutrient and microbial source tracking in an agricultural watershed.

Estuaries often experience multiple water quality impairments including nitrogen enrichment and elevated fecal pollution. These pollutant sources are often linked and difficult to characterize, especially in multiple use watersheds, hindering the identification of effective mitigation steps. Tillamook Bay (Oregon, USA) has a mixed-use watershed including many potential nutrient and fecal bacteria sources due to agricultural activities, human development, and local wildlife populations.

National outbreak of Shiga toxin-producing O145:H28 associated with pre-packed sandwiches, United Kingdom, May-June 2024.

Shiga toxin-producing (STEC) is a group of bacteria that causes gastrointestinal illness and occasionally causes large foodborne outbreaks. It represents a major public health concern due to its ability to cause severe illness which can sometimes be fatal. This study was undertaken as part of a rapid investigation into a national foodborne outbreak of STEC O145.

Poststroke hyperglycemia dysregulates cap-dependent translation in neural cells.

Aims: Post stroke hyperglycemia has been shown to deter functional recovery. Earlier findings have indicated the cap-dependent translation regulator 4E-BP1 is detrimentally upregulated in hyperglycemic conditions. The present study aims to test the hypothesis that hyperglycemic ischemic reperfusion injury (I/R) affects normal protein translation poststroke.

Hyperglycemia Inhibits AAA Expansion: Examining the Role of Lysyl Oxidase.

Abdominal aortic aneurysm (AAA) is a common, progressive and potentially fatal dilation of the most distal aortic segment. Multiple studies with longitudinal follow-up of AAA have identified markedly slower progression among patients affected with diabetes. Understanding the molecular pathway responsible for the growth inhibition could have implications for therapy in nondiabetic AAA patients.
