We have investigated the relationship between the suppression of acidity by antisecretory drugs for the treatment of benign gastric ulcer and their corresponding ulcer-healing rates. For a variety of antisecretory drug regimens, there was a significant correlation between suppression of 24-h intragastric acidity and ulcer healing rates after 2, 4 and 8 weeks of treatment. There was a lesser degree of correlation between healing and suppression of nocturnal acidity and the association between suppression of acidity and gastric-ulcer healing rates was less marked than that previously described for duodenal ulcer.

Multiple myeloma (MM) remains an incurable hematological malignancy that necessitates the identification of novel therapeutic strategies. Here, we report that intracellular levels of very long chain fatty acids (VLCFAs) control the cytotoxicity of MM chemotherapeutic agents. Inhibition of VLCFA biosynthesis reduced cell death in MM cells caused by the proteasome inhibitor, bortezomib.

Small-molecule pectin (SMP) extracted from the leaves of Premna ligustroides Hemsl, with a molecular weight range of 5000-35,000 Da, has demonstrated anti-inflammatory and lipid-lowering properties in vitro. This study explored the effects of SMP on hypercholesterolemia in mice, with a focus on inflammation, lipid profiles, and cholesterol metabolism. Mice received SMP at doses of 607, 303, and 152 mg/kg body weight.

Plant lipids are a diverse group of biomolecules that play essential roles in plant architecture, physiology, and signaling. To advance our understanding of plant biology and facilitate innovations in plant-based product development, we must have precise methods for the comprehensive analysis of plant lipids. Here, we present a comprehensive overview of current research investigating plant lipids, including their structures, metabolism, and functions.

Photocatalytic upcycling of waste polyolefins into value-added chemicals provides promise in plastic waste management and resource utilization. Previous works demonstrate that polyolefins can be converted into carboxylic acids, with CO as the final oxidation product. It is still challenging to explore more transformation products, particularly mild-oxidation products such as alcohols, because of their instability compared with polymer substrates, which are prone to oxidation during catalytic reactions.

This study investigated endophytic fungi isolated from the medicinal plant Panax notoginseng. Among these, the endophytic fungus SQ3, identified as Chaetomium globosum, was capable of reducing silver ions to form metallic silver nanoparticles. The green-synthesized silver nanoparticles (AgNPs) presented a distinct surface plasmon resonance peak at 424 nm, with particle sizes between 2.
