The sow vaginal and gut microbiota associated with longevity and reproductive performance.

Background: Sow longevity and reproductivity are essential in the modern swine industry. Although many studies have focused on the genetic and genomic factors for selection, little is known about the associations between the microbiome and sows with longevity in reproduction.

Results: In this study, we collected and sequenced rectal and vaginal swabs from 48 sows, nine of which completed up to four parities (U4P group), exhibiting reproductive longevity.

Glial Biologist's Guide to Mass Spectrometry-Based Lipidomics: A Tutorial From Sample Preparation to Data Analysis.

Neurological diseases are associated with disruptions in the brain lipidome that are becoming central to disease pathogenesis. Traditionally perceived as static structural support in membranes, lipids are now known to be actively involved in cellular signaling, energy metabolism, and other cellular activities involving membrane curvature, fluidity, fusion or fission. Glia are critical in the development, health, and function of the brain, and glial regulation plays a major role in disease.

Lipids: Emerging Players of Microglial Biology.

Lipids are small molecule immunomodulators that play critical roles in maintaining cellular health and function. Microglia, the resident immune cells of the central nervous system, regulate lipid metabolism both in the extracellular environment and within intracellular compartments through various mechanisms. For instance, glycerophospholipids and fatty acids interact with protein receptors on the microglial surface, such as the Triggering Receptor Expressed on Myeloid Cells 2, influencing cellular functions like phagocytosis and migration.

Centralized Colorectal Cancer Screening Outreach in Federally Qualified Health Centers: A Randomized Clinical Trial.

Importance: Colorectal cancer (CRC) screening is effective but remains underused in federally qualified health centers (FQHCs).

Objective: To assess the effectiveness of a centralized CRC screening outreach intervention involving mailed fecal immunochemical testing (FIT) outreach and patient navigation to colonoscopy after abnormal results of FIT.

Design, Setting, And Participants: A pragmatic randomized clinical trial was conducted, using intention-to-treat analysis.

Dietary soy protein reverses obesity-induced liver steatosis and alters fecal microbial composition independent of isoflavone level.

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a major public health concern that is exacerbated by the obesity pandemic. Dietary interventions have the potential to alleviate obesity-associated MASLD through variable mechanisms, including optimizing the gut microbiota. Previously, we reported that soy protein concentrate (SPC) with low or high levels of isoflavone (LIF or HIF) protected young obese Zucker rats from developing liver steatosis.
