Putrescine transformation to other forms of polyamines in filling grain embryos functioned in enhancing the resistance of maize plants to drought stress.

Polyamines (PAs), one of plant growth regulators, play an important role in the plant resistance to drought stress. However, the precise function of putrescine (Put) transformation to other forms of PAs is not clear in filling maize grain embryos. In this study, two maize (Zea mays L.

Dexamethasone affects the chemotaxis and phagocytic activity of neutrophils for boar spermatozoa and the quality of liquid preserved boar semen in vitro.

This study aimed to investigate the effect of dexamethasone (DEX) on chemotaxis and phagocytic activity of neutrophils for spermatozoa and semen quality of preserved boar semen. The different concentrations of dexamethasone were added to boar semen dilutions to detect its effects on the chemotaxis of neutrophils and phagocytosis of neutrophils and sperm motility sperm malformation rate, plasma membrane integrity, mitochondrial activity, and spermatozoa motility parameters. The study results showed that the experimental groups of DEX significantly inhibited the phagocytosis and chemotaxis of PMNs for spermatozoa.

Greater Adherence to Dietary Guidelines Associated with Reduced Risk of Cardiovascular Diseases in Chinese Patients with Type 2 Diabetes.

The evidence regarding the impact of the scores on healthy eating indices on the risk of cardiovascular events among patients with type 2 diabetes (T2D) is limited.

Epigallocatechin Gallate Attenuates β-Amyloid Generation and Oxidative Stress Involvement of PPARγ in N2a/APP695 Cells.

The accumulation of β-amyloid (Aβ) peptide plaques is a major pathogenic event in Alzheimer's disease (AD). Aβ is a cleaved fragment of APP via BACE1, which is the rate-limiting enzyme in APP processing and Aβ generation. Nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is considered to be a potential target for AD treatment, because of its potent antioxidant and inhibitory effects on Aβ production by negatively regulating BACE1.

Fuzhisan Ameliorates the Memory Deficits in Aged SAMP8 Mice via Decreasing Aβ Production and Tau Hyperphosphorylation of the Hippocampus.

The pathological features of Alzheimer's disease (AD) include extracellular neuritic plaques containing β-amyloid (Aβ) peptide, a cleaved fragment of amyloid precursor protein (APP) via β-site amyloid precursor protein-cleaving enzyme 1 (BACE1) and intracellular neurofibrillary tangles (NFTs) composed of hyperphosphorylated tau. Cyclin-dependent kinase 5 (Cdk5) is increasingly thought to play a pivotal role in the pathogenesis of AD, both as a regulator of the production of Aβ and through its well-established role as a tau kinase. Fuzhisan (FZS), a Chinese herbal complex prescription, has been used for the treatment AD for over 20 years, and is known to enhance the cognitive ability in AD patients as well as in AD model rats.
