Effects of immersion bathing in Lactobacillus plantarum CLY-05 on the growth performance, non-specific immune enzyme activities and gut microbiota of Apostichopus japonicus.

In order to study the optimal use of Lactobacillus plantarum in sea cucumber (Apostichopus japonicus), 49 days feeding trial was conducted to determine the influence of immersion bathing in different concentrations of Lactobacillus plantarum CLY-05 on body weight gain rate and non-specific immune activities. The potential effect of CLY-05 on gut microbiota was also analyzed during the immersion bathing at the optimum concentration. The results showed that the body weight growth rate of all bathing groups was higher than that of control.

Background: Acetyl phosphate (AcP) is a microbial intermediate involved in the central bacterial metabolism. In bacteria, it also functions as a donor of acetyl and phosphoryl groups in the nonenzymatic protein acetylation and signal transduction. In host, AcP was detected as an intermediate of the pyruvate dehydrogenase complex, and its appearance in the blood was considered as an indication of mitochondrial breakdown.

Ammonia, a ubiquitous contaminant in aquatic ecosystems, poses multifaceted threats to fish species at elevated concentrations. In order to investigate the toxic effects of chronic ammonia stress on the liver of juvenile , the present experiment was conducted to investigate the differences in changes in liver tissue structure, enzyme activities, and metabolomes after 28 days of ammonia exposure (0, 4, 8, and 16 mg/L). The findings revealed that ammonia exposure induced significant oxidative stress in the liver, manifesting in decreased activities of antioxidant enzymes SOD and GSH-Px, elevated levels of GSH, GST, and MDA, and heightened activities of immune enzymes LZM, ALP, and ACP.

Background: Human adamantinomatous craniopharyngioma (ACP) is a brain tumor that originates at the base of the skull and shows aggressive local behavior, invading sensitive structures such as the optic pathways and hypothalamus. The conventional treatment of the tumor has been surgery and radiotherapy with the consequent development of serious sequelae. It is well known that Substance P (SP) peptide and Neurokinin-1 receptor (NK-1R) are involved in inflammation and cancer progression and its blockage with NK-1R antagonists has been shown to effectively counteract tumor development in preclinical trials.

The lack of effective treatments for dry age-related macular degeneration (AMD) is in part due to a lack of a preclinical animal model that recapitulates features of the clinical state including macular retinal pigment epithelium (RPE) degeneration, also known as geographic atrophy (GA). A nonhuman primate model of GA was developed and its responsiveness to an approved treatment, avacincaptad pegol (ACP), a complement C5 inhibitor, was evaluated. Intravitreal (ivt) administration of sodium iodate (SI) into one eye of male Macaca fascicularis leads to retinal areas (mm) of hyper- or hypo-autofluorescence.
