The role of hydrogen sulphide (H S) in angiogenesis has been widely demonstrated. Vascular endothelial growth factor (VEGF) plays an important role in H S-induced angiogenesis. H S promotes angiogenesis by upregulating VEGF via pro-angiogenic signal transduction. The involved signalling pathways include the mitogen-activated protein kinase pathway, phosphoinositide-3 kinase pathway, nitric oxide (NO) synthase/NO pathway, signal transducer and activator of transcription 3 (STAT3) pathway, and adenosine triphosphate (ATP)-sensitive potassium (K ) channels. H S has been shown to contribute to tumour angiogenesis, diabetic wound healing, angiogenesis in cardiac and cerebral ischaemic tissues, and physiological angiogenesis during the menstrual cycle and pregnancy. Furthermore, H S can exert an anti-angiogenic effect by inactivating Wnt/β-catenin signalling or blocking the STAT3 pathway in tumours. Therefore, H S plays a double-edged sword role in the process of angiogenesis. The regulation of H S production is a promising therapeutic approach for angiogenesis-associated diseases. Novel H S donors and/or inhibitors can be developed in the treatment of angiogenesis-dependent diseases.

In this study, polyethylene glycol 200 (PEG200) was employed as hydrogen bond acceptor, while organic acids served as hydrogen bond donors, to formulate poly-deep eutectic solvents (PDESs), which were utilized to pretreat tea stem. Specially, combining PEG200 and oxalic acid (OA) exhibited a notably high cellulose retention (82.03 %) and most efficient hemicellulose (97.

Naphthalene acetic acid (NAA) is an auxin plant growth regulator (PGR) and widely used to regulate the growth process of plants. As excessive NAA enter the environment, it damages the ecological environment and endangers human life and health. Layered bimetallic hydroxides (LDHs) are widely used for the adsorption of pollutants due to their large surface area and excellent structural properties.

Acute alcohol intoxication could cause multiorgan damage, including nervous, digestive, and cardiovascular systems, and in particular, irreversible damage to the brain and liver. Emerging studies have revealed that the endogenous multienzymatic antioxidant defense system (MEAODS) plays a central role in preventing oxidative stress and other toxicological compounds produced by alcohol. However, few available drugs could quickly regulate MEAODS.
