This paper aimed to explore the mechanism of tetrapeptide VTPY in improving alcoholic gastric injury. VTPY has the potential to enhance the growth and movement of normal GES-1 cells. Following ethanol-induced impairment， VTPY effectively improved migration of GES-1 and HUVEC cells， enhanced angiogenesis， eliminated cellular and mitochondrial ROS， inhibited excessive mitochondrial division， enhanced F-actin polymerization and mitochondrial respiratory capacity. To counteract excessive mitochondrial fission， VTPY primarily restores the mitochondria dynamics by reducing the expression of Drp1 and Fis1， while increasing Mfn2. Further studies utilizing inhibitors clarifies that the inhibition of excessive mitochondrial fission can markedly reduce F-actin depolymerization， consequently enhancing cell migration. Additionally， VTPY can inhibit the apoptosis pathway by maintaining potential of mitochondrial membrane， preventing the release of mitochondrial cytochrome c， bolstering the levels of Bcl-XL， while reducing the levels of Bax and cleaved-caspase3. Further investigations using inhibitors demonstrates that excessive mitochondrial fission could activate apoptotic pathway. However， VTPY counteracts this effect and enhance cells viability. Further evidence suggests that VTPY effectively improves ulcer index and pathologic changes， relieves inflammation， enhances the balance of oxidation and anti-oxidation， promotes angiogenesis， improves the expression of mitochondrial dynamics factors， blocks apoptotic pathway， and subsequently ameliorates gastric damage in mice through Fis-1/Bcl-2 pathway.

Influence of Microorganisms Effective against Basal Rot and on Agronomic Parameters of Onion [Allium cepa L. (Amaryllidaceae)]

Onions are a horticultural crop of great economic, dietary and medicinal importance, and are highly prized by the Ivorian population. However, production remains low, due to a number of constraints, including parasitic attacks. The most frequent is fusariosis caused by Fusarium sp., a pathogen that causes enormous damage to onion crops. Faced with these attacks, chemical control appears to be ineffective, with consequences for human health and the environment. This is why the search for effective alternative methods that respect the environment and human health is so necessary. It is in this context that this study was carried out, with the general aim of controlling fusarium wilt in onion crops, with a view to improving onion production in Ivory Coast through the use of effective microorganisms. The experimental set-up used for this purpose was a fisher block with complete randomization, comprising three replicates. A fungal spore concentration of 106 spore/mL of Fusarium sp., three doses (1%;2.5% and 5% v/v) of EM and one dose of a chemical fungicide (30 mL/16L) were tested on young onion plants. Each block consisted of nine sub-plots with nine treatments. Health parameters (incidence and severity) and agronomic parameters (growth and yield) were assessed. Microbiological analysis of the EM revealed the presence of nine morphotypes of Trichoderma sp., Aspergillus clavatus, Aspergillus flavus, Aspergillus sp., Penicillium sp., Rhizopus sp., lactic acid bacteria of the Bacillus family and the yeast Saccharomyces cerevisiae. Field experimentation showed that the 5% EM microbial solution reduced the incidence and severity of fusariosis compared with the chemical fungicide, and proved to be the best. This dose reduced yield losses by 7.14%, while improving onion growth and yield by over 5%. The results demonstrated the ability of the EM solution to effectively control the causal agent of basal rot in onion crops.
