refers to a group of rare medicinal fungi with remarkable therapeutic properties. However, current knowledge on the bioactive ingredients and antioxidant activities of different species of this genus is limited. In this study, a total of 15 wild strains from 8 species of were selected as the experimental materials for identification of the bioactive components (polysaccharide, polyphenol, flavonoid, triterpenoid, and ascorbic acid) and antioxidant activities (scavenging activities against hydroxyl, superoxide, DPPH, and ABTS radicals; superoxide dismutase activity; and ferric reducing ability of plasma). Notably, individual strains contained different levels of various indicators, among which Cui 3573, Cui 14419 and Cui 14441, Dai 9061, and Dai 10841 displayed the strongest activities. The correlation analysis of bioactive ingredients and antioxidant activities revealed that the antioxidant capacity of is mainly associated with the contents of flavonoid and ascorbic acid, followed by polyphenol and triterpenoid, and finally, polysaccharide. Together, the results obtained from the comprehensive and systematic comparative analyses contribute further potential resources and critical guidance for the separation, purification, and further development and utilization of bioactive agents from wild species, as well as the optimization of their artificial cultivation conditions.

Bacillus coagulans alleviates hepatic injury caused by Klebsiella pneumoniae in rabbits.
PLoS One
January 2025
College of Animal Science and Technology, Henan University of Science and Technology, Luoyang, China.
Background: As an opportunistic bacterial pathogen, Klebsiella pneumoniae (KP) is prone to causing a spectrum of diseases in rabbits when their immune system is compromised, which poses a threat to rabbit breeding industry. Bacillus coagulans (BC), recognized as an effective probiotic, confers a variety of benefits including anti-inflammatory and antioxidant properties.
Aim: The purpose of this study was to investigate whether dietary BC can effectively alleviate hepatic injury caused by KP.
Effect of Sertraline and Vortioxetine on Stress-Induced Brain Injury in Rats: Biochemical and Histopathological Evaluations.
Clin Neuropharmacol
January 2025
Medical Biochemistry, Erzincan Binali Yıldırım University Faculty of Medicine, Erzincan, Turkey.
Objectives: Our aim was to evaluate the comparative effects of sertraline and vortioxetine against stress-induced brain injury in rats.
Methods: The rats were assigned to a nonstress group (NSG), stress-treated control (StC), sertraline + stress (SSt), and vortioxetine + stress (VSt) groups. Sertraline and vortioxetine (10 mg/kg) were given orally by gavage to the SSt and VSt groups.
Sensory Characteristics and Impact of Flavanol-Rich Grape and Blueberry Extract on Blood Flow Velocity and Oxidative Stress.
J Diet Suppl
January 2025
Department of Biomedical and Biotechnological Sciences, University of Catania, Catania, Italy.
Background: Several epidemiological studies and intervention trials have demonstrated that grapes and blueberries, which are rich in flavanols, can lower the risk of cardiovascular disease. However, the mechanisms of action of these compounds remain unclear due to their low bioavailability.
Objective: This study aimed to characterize the sensory properties, blood flow velocity, and oxidative stress of a polyphenol rich grape and blueberry extract (PEGB) containing approximately 16% flavanols (11% monomers and 4% dimers).
Metformin Alleviates Doxorubicin-Induced Cardiotoxicity via Preserving Mitochondrial Dynamics Balance and Calcium Homeostasis.
Appl Biochem Biotechnol
January 2025
Department of Pharmacology, Faculty of Veterinary Medicine, Assiut University, Assiut, 71516, Egypt.
Doxorubicin (DOX) is a commonly used chemotherapeutic medication for treating malignancies, although its cardiotoxicity limits its use. There is growing evidence that alteration of the mitochondrial fission/fusion dynamic processes accompanied by excessive reactive oxygen species (ROS) production and alteration of calcium Ca homeostasis are potential underlying mechanisms of DOX-induced cardiotoxicity (DIC). Metformin (Met) is an AMP-activated protein kinase (AMPK) activator that has antioxidant properties and cardioprotective effects.

Proc Natl Acad Sci U S A

Department of Entomology, University of California, Riverside, CA 92521.
Female mosquitoes require a vertebrate blood meal to activate reproduction, transmitting numerous devastating human diseases. Vitellogenesis is a central event of female reproduction that involves the massive production of vitellogenin (Vg) in the fat body and the maturation of ovaries. This process is controlled by the steroid hormone 20-hydroxyecdysone (20E); however, its molecular regulatory basis remains not completely understood.
