BACKGROUND The production of secondary metabolites with antibiotic properties is a common characteristic to entomopathogenic bacteria Xenorhabdus spp. These metabolites not only have diverse chemical structures but also have a wide range of bioactivities with medicinal and agricultural interests such as antibiotic, antimycotic and insecticidal, nematicidal(More)
Progesterone is an efficient candidate for treating stroke and traumatic brain damage. The current study was designed to investigate the effects of progesterone on glucose transporter proteins (GLUT1 and GLUT3) during hypoxic-ischemic injury in a neonatal rat model. We demonstrated strong staining for GLUT1 in the walls of blood vessels and GLUT3(More)
Lactobacillus salivarius is a member of the indigenous microbiota of the human gastrointestinal tract (GIT), and some L. salivarius strains are considered as probiotics. Bile tolerance is a crucial property for probiotic bacteria to survive the transit through the GIT and exert their beneficial effects. In this work, the functional role of oppA encoding an(More)
The present study aimed to explore the mechanism underlying the protective effects of hydrogen sulfide against neuronal damage caused by cerebral ischemia/reperfusion. We established the middle cerebral artery occlusion model in rats via the suture method. Ten minutes after middle cerebral artery occlusion, the animals were intraperitoneally injected with(More)
Lactobacillus delbrueckii subsp. bulgaricus develops acid tolerance response when subjected to acid stress conditions, such as the induction of enzymes associated with carbohydrate metabolism. In this study, pyk gene encoding pyruvate kinase was over-expressed in heterologous host Lactococcus lactis NZ9000, and SDS-PAGE analysis revealed the successful(More)
Lactobacillus strains producing bacteriocins have attracted highly attention as probiotic cultures in animal nutrition since the use of antibiotics was forbidden in the livestock industry. Lactobacillus plantarum LB-B1 isolated from the fermented dairy product can produce pediocin PA-1, which has a strong inhibition of Listeria but hardly any influence on(More)
Nrf2 expression. These results suggest that IDS-T2DM induces testicular cell death presumably through caspase-8 activation and mitochondria-mediated cell death pathways, and also by significantly down-regulating testicular Nrf2 expression and function. SFN up-regulates testicular Nrf2 expression, and its target antioxidant expression, which was associated(More)
