Unripe fruits of Litchi chinensis (Gaertn.) Sonn: An overview of its toxicity
Ann Pharm Fr. 2023 Jul 11:S0003-4509(23)00073-1. doi: 10.1016/j.pharma.2023.07.004. Online ahead of print.ABSTRACTLitchi (Litchi chinensis) is a widely consumed fruit that has been used in many food and health-promoting products worldwide. Litchi is a good source of nutrients including vitamin and minerals, dietary fibers, proteins, and carbohydrates. Of note, several studies have reported that the constituents of litchi fruits elicit antioxidant properties and help to maintain blood pressure, and reduce the risk of stroke and heart attack. An unclearly explained outbreak occurred in June 2019 in Muzaffarpur (Bihar), India...

The CaMKII α hub ligand Ph-HTBA promotes neuroprotection after focal ischemic stroke by a distinct molecular interaction
In this study, we functionally characterize the novel and brain permeable GHB analog (E)-2-(5-hydroxy-2-phenyl-5,7,8,9-tetrahydro-6H-benzo[7]annulen-6-ylidene)acetic acid (Ph-HTBA). Administration of a single dose of Ph-HTBA at a clinically relevant time point (3-6 h after photothrombotic stroke) promotes neuroprotection with a superior effect at low doses compared to the smaller GHB analog 3-hydroxycyclopent-1-enecarboxylic acid (HOCPCA). In contrast to HOCPCA, Ph-HTBA reduces Ca2+-stimulated CaMKIIα Thr286 autophosphorylation in primary cortical neurons and substrate phosphorylation of recombinant CaMKIIα, potentially ...

Shengui Sansheng San Ameliorates Cerebral Energy Deficiency via Citrate Cycle After Ischemic Stroke
Conclusion In summary, SSS extraction significantly ameliorates cerebral energy metabolism via boosting citrate cycle, which mainly embodies the enhancements of blood glucose concentration, glucose and lactate transportation and glucose utilization, as well as the regulations of relative enzymes activities in citrate cycle. These ameliorations ultimately resulted in numerous ATP yield after stroke, which improved neurological function and infarcted volume. Collectively, it suggests that SSS extraction has exerted advantageous effect in the treatment of cerebral ischemia. Ethics Statement All animal operations were accor...

Canagliflozin Inhibits Human Endothelial Cell Proliferation and Tube Formation
In conclusion, the present study identified canagliflozin as a potent inhibitor of human EC proliferation. The anti-proliferative action of canagliflozin is observed in ECs isolated from both the venous and arterial circulation, and is partly due to the blockade of cyclin A expression. In addition, this study found that canagliflozin inhibits tube formation in cultured ECs and mouse aortic rings. Notably, these actions are specific for canagliflozin and not seen with other SGLT2 inhibitors. The ability of canagliflozin to exert these pleiotropic effects on EC function may contribute to both the adverse and salutary actions...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

YiQiFuMai Powder Injection Attenuates Coronary Artery Ligation-Induced Heart Failure Through Improving Mitochondrial Function via Regulating ROS Generation and CaMKII Signaling Pathways
This study was carried out in accordance with the recommendations of “Guide for the Care and Use of Laboratory Animals, National Institutes of Health.” The protocol was approved by the “China Pharmaceutical University.” Surgical Preparation The mice were anesthetized with chloral hydrate (4% chloral hydrate, ip). The HF model was induced by CAL as previously reported (Gao et al., 2010). Successful ligation of the coronary artery was confirmed by the occurrence of ST-segment elevation in electrocardiogram. Sham operated mice were performed the same process except left CAL. After ligation, the h...
