This study aimed to evaluate the influence of low doses of 2,4-D on the agronomic traits of upland rice applied at different stages of crop growth. The work was carried out in a randomized completly blocks, and consisted of the application of 5 low doses of the 2,4-D herbicide (0, 0.68, 1.36, 2.04, 3.40 and 5.44 g acid equivalent (e.a.) ha) in two stages of rice development (tillering and floral differentiation). Nitrogen contentes in leaves, SPAD index and yield are higher when low doses of 2,4-D is applied in the tillering stage. Application of 2,4-D at a dose of 2.04 g a.e ha results in a 19% increase in the number of spikelet per panicle. On the other hand, there is no effect of the application of low doses of 2,4-D on height, number of stems, active tillering and weight of 100 seeds. Our results contribute to increase knowledge of the hormesis effect in plants in order to increase crop yield.

Oxidative stress and inflammation are indispensable components of ischemia-reperfusion (IR) injury. In this study, we investigated the effects of low and high doses of caftaric acid (CA) on reducing kidney and remote organ damage induced by IR. We divided Wistar rats into four groups: sham, IR, low (40 mg/kg body weight (BW)), and high (80 mg/kg BW) CA groups.

Lipid rafts are subdomains of the cell membrane that are rich in cholesterol and glycolipids, and they are involved in various cellular processes and pathophysiological mechanisms. However, the specific role of lipid rafts in hepatocyte dysfunction during the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD) is not fully understood. In this study, we investigated the impact of lipid rafts on insulin sensitivity and hepatocyte injury induced by saturated free fatty acids (sFFAs) using primary-cultured mouse hepatocytes.

Objective: He Shi Yu Lin Formula (HSYLF) is a clinically proven prescription for treating premature ovarian insufficiency (POI), and has shown a good curative effect. However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.

This study aimed to investigate the protective effects of Lycium barbarum polysaccharide (LBP) on digestive function and intestinal barrier integrity in septic mice, and to explore its underlying mechanisms. A total of 70 healthy male BALB/C mice were randomly assigned into five groups: blank control group (BG, n = 12), control group (CG, n = 12), low-dose group (LDG, n = 12, 200 mg/kg), medium-dose group (MDG, n = 12, 400 mg/kg), and high-dose group (HDG, n = 12, 800 mg/kg). A sepsis model was established by cecal ligation and puncture, followed by treatment with different doses of LBP.

Background: Gamma radiation at low doses might have potential health effects in long-term exposure. The current study was aimed to search cell death pathway and inflammatory biomarkers in nuclear medicine workers with long-term exposure to gamma radiation.
Material And Methods: Fifty cases with a history of 10 years' exposure to gamma radiation and 30 normal individuals were included in the current study.
