Background: Many patients seek complementary medicine treatments like neutraceuticals for common conditions such as hypertension.
Methods: We conducted a placebo-controlled prospective randomized crossover study in 10 hypertensive subjects to determine whether a single dose of a hydrolysate of bovine milk protein (designated C12 peptide; low and high dose), either alone or combined with alginic acid (low and high dose), reduced daytime blood pressure (BP), as determined by ambulatory BP monitoring.
Results: Within the five treatment regimens a significant reduction of 9.2 +/- 3.2 mm Hg in systolic BP at h 6 compared with h 2 occurred on the higher dose of alginic acid (1754 mg) combined with C12 (P = .02). The C12 peptide with the higher dose of alginic acid also showed a significant reduction of 6.0 +/- 2.0 mm Hg in diastolic BP at h 6 compared with h 2 (P = .015).
Conclusions: These preliminary data are encouraging and deserve testing in a larger and longer treatment trial.

Aims: We sought to characterize the clinical course of patients following worsening heart failure (WHF) treated in an outpatient setting and to identify factors associated with a poor response to standard of care with loop diuretics.
Methods And Results: Between September 2022 and March 2023, 44 eligible patients (mean age 66.3 years, 84% male) with ejection fraction <50% and with WHF symptoms in the preceding week treated in an outpatient setting were enrolled.

This study focuses on a novel lipase from Bacillus licheniformis IBRL-CHS2. The lipase gene was cloned into the pGEM-T Easy vector, and its sequences were registered in GenBank (KU984433 and AOT80658). It was identified as a member of the bacterial lipase subfamily 1.

Episodic memory (EM) alterations are a hallmark of Alzheimer's disease (AD). We assessed EM longitudinally in cognitively normal elders at-risk for AD (with subjective memory complaints), as a function of amyloid-β (Aβ) burden, neurodegeneration (N), and progression to prodromal AD. We stratified 264 INSIGHT-preAD study subjects in controls (Aβ-/N-), stable/N- or N + (Aβ +), and progressors/N- or N + (Aβ +) groups (progressors were included only until AD-diagnosis).

Defining suitable enzymes for reaction steps in novel synthetic pathways is crucial for developing microbial cell factories for non-natural products. Here, we developed a computational workflow to identify C12 alcohol-active UDP-glycosyltransferases. The workflow involved three steps: (1) assembling initial candidates of putative UDP-glycosyltransferases, (2) refining selection by examining conserved regions, and (3) 3D structure prediction and molecular docking.

Background: As a feed additive, medium-chain fatty acids (MCFAs)/medium-chain fatty acid triglycerides (MCTs) have been used in ruminant production, but mostly added in the form of mixed esters. Studies have shown that MCTs may have a positive effect on feed intake or oxidative stress in animals, but it is unclear which MCT could play a role, and the mechanism has not been elucidated. In this study, the effects of individual MCT on growth performance, serum intake-related hormones, and oxidative stress indices in finishing bulls were investigated and further studied the effects of MCT supplementation on gastrointestinal tract bacteria and rumen fluid metabolomics.
