Ambient particle composition and toxicity in 31 major cities in China
Fundamental ResearchCurrent assessment of air quality or control effectiveness is solely based on particulate matter (PM) mass levels, without considering their toxicity differences in terms of health benefits.

Identifying and improving the fibre-degrading activity of rumen microbe-derived fibrolytic bacteria : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, Manawatū, New Zealand [PDF]
, 2017 The dairy industry is extremely important to the New Zealand (NZ) economy, and it accounts for approximately $16.6 billion in exports each year. In NZ, traditional feedstock for cattle, such as grass and hay, consists of cellulose-based fibrous material ...

Advanced Science, EarlyView.Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.

Adhesion‐Related Macrophages Regulate Metabolic Homeostasis Through CAV‐1 Dependency
Advanced Science, EarlyView.Adipose tissue harbors a distinct macrophage subpopulation, termed adhesion‐related macrophages (ARMs), which stably adhere to adipocytes. In obesity, ARMs represent the major expanding macrophage subset. They acquire material from adipocytes and rely on Caveolin‐1 for sustained lipid handling.

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair
Advanced Science, EarlyView.This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Advanced Science, EarlyView.We demonstrate that Cars2, a cysteine catabolic enzyme in mouse iBAT, is critical for cold tolerance and brown adipocyte differentiation. Through its CPERS activity, Cars2 produces CysSSH/H2S to induce EBF2 persulfidation, promoting its interaction with PPARγ and BRG1 to enhance thermogenic gene expression.

Hamster leukemia virus: lack of endogenous DNA synthesis and unique structure of its DNA polymerase [PDF]
, 1974 Infectious hamster leukemia virus (HaLV) contains a DNA polymerase different from those of murine and avian viruses. No endogenous reaction directed by the 60 to 70S RNA of HaLV could be demonstrated in detergenttreated HaLV virions, nor could the ...
