Solid-object density standards developed independently by the Istituto di Metrologia "G. Colonnetti" (IMGC) and NBS, and traceable to SI units of length and mass, have been compared using a silicon transfer standard. Results agree to approximately 1×10, which is conistent with the uncertainties assigned by the two laboratories.

Background: Binding of ANGPTL (angiopoietin-like protein)-3 to ANGPTL8 generates a protein complex (ANGPTL3/8) that strongly inhibits LPL (lipoprotein lipase) activity, as compared with ANGPTL3 alone, suggesting that ANGPTL3/8 concentrations are critical for the regulation of circulation lipoprotein concentrations and subsequent increased coronary heart disease (CHD) risk. To test this hypothesis in humans, we evaluated the associations of circulating free ANGPTL3 and ANGPTL3/8 complex concentrations with lipoprotein concentrations and CHD risk in 2 prospective cohort studies.
Methods: Fasting blood samples were obtained in conjunction with the baseline evaluation of 9479 subjects from 2 population-based Swedish cohorts of middle-aged men and women.

Purpose: Chronic exposure to synthetic glucocorticoids/GCs, widely in use to treat many diseases, may compromise the hypothalamic-pituitary-adrenal/HPA axis leading to a condition of adrenal insufficiency/AI. This study demonstrates the efficacy of the melatonin/MEL in amelioration of chronic dexamethasone (DEX)-induced AI.
Methods: Mice (Parkes Strain/Male/8 weeks old/30-33 g) were maintained in four groups (10 mice/group) for 30 days: Group 1/Control received intraperitoneal (i.

Collective behavior in biological systems emerges from local interactions among individuals, enabling groups to adapt to dynamic environments. Traditional modeling approaches, such as bottom-up and top-down models, have limitations in accurately representing these complex interactions. We propose a novel potential field mechanism that integrates local interactions and environmental influences to explain collective behavior.

Background: Comprehensive management of acute coronary syndrome (ACS) requires seamless treatment across institutions, including intensive care centers and local clinics. However, maintaining guideline-directed medical therapy remains challenging. One promising option to improve the situation may be the implementation of regional collaborative clinical pathways.

Introduction: National malaria programmes must weigh the relative benefits of different vector control and elimination tools to prioritise resource allocation with the greatest impact. This study assesses the epidemiological and entomological impacts of piperonyl butoxide insecticide-treated nets (PBO ITN-only arm) compared with the combination of two annual non-pyrethroid indoor residual spraying (IRS) campaigns and standard pyrethroid ITNs (IRS+Standard Pyrethroid ITN arm) in the Amhara region of Ethiopia.
Methods: An open-label, stratified block-cluster randomised trial was designed to compare the impacts of the two intervention arms.
