Article Synopsis
  • The study investigated how natural killer cell activity (NKA) relates to the severity of rheumatoid arthritis (RA) by analyzing data from 259 patients.
  • Patients were split into low NKA (< 100 pg/mL) and high NKA (100-250 pg/mL) groups, with the low NKA group showing more severe RA symptoms and higher usage of TNF-α antagonists.
  • Results indicated a negative correlation between NKA levels and various measures of RA severity, suggesting that lower NKA is associated with worse disease characteristics and increased inflammation.

Internal states drive survival behaviors, but their neural implementation is poorly understood. Recently, we identified a line attractor in the ventromedial hypothalamus (VMH) that represents a state of aggressiveness. Line attractors can be implemented by recurrent connectivity or neuromodulatory signaling, but evidence for the latter is scant.

The expression of two major virulence factors of , cholera toxin (CT) and toxin co-regulated pilus (TCP), is induced by environmental stimuli through a cascade of interactions among regulatory proteins known as the ToxR regulon when the bacteria reach the human small intestine. ToxT is produced via the ToxR regulon and acts as the direct transcriptional activator of CT (), TCP ( gene cluster), and other virulence genes. Unsaturated fatty acids (UFAs) and several small-molecule inhibitors of ToxT have been developed as antivirulence agents against .

The inclusion of exogenous phytase in P- and Ca-deficient diets of broilers to address the growing concern about excessive P excretion into the environment over the years has been remarkably documented. However, responses among these studies have been inconsistent because of the several factors affecting P utilization. For this reason, a systematic review with a meta-analysis of results from forty-one studies published from 2000 to February 2024 was evaluated to achieve the following: (1) quantitatively summarize the size of phytase effect on growth performance, bone strength and mineralization in broilers fed diets deficient in P and Ca and (2) estimate and explore the heterogeneity in the effect size of outcomes using subgroup and meta-regression analyses.
