day 7 after TBI were reduced by necrostatin-1-containing regimens; however, normalization of plasma protein levels at day 7 required the addition of JP4-039 and baicalein. These findings indicate that mitigator targeting to three distinct cell death pathways increases survival after TBI.Vitamin B12 and propionic acid that were simultaneous produced by Propionibacterium freudenreichii are both favorable chemicals widely used in food preservatives, medicine, and nutrition. While the carbon source and propionic acid accumulation reflected fermentation efficiency. In this study, using corn stalk as a carbon source and fed-batch fermentation process in an expanded bed adsorption bioreactor was studied for efficient and economic biosynthesis of acid vitamin B12 and propionic. With liquid hot water pretreated corn stalk hydrolysates as carbon source, 28.65 mg L-1 of vitamin B12 and 17.05 g L-1 of propionic acid were attained at 168 h in batch fermentation. In order to optimize the fermentation outcomes, fed-batch fermentation was performed with hydrolyzed corn stalk in expanded bed adsorption bioreactor (EBAB), giving 47.6 mg L-1 vitamin B12 and 91.4 g L-1 of propionic acid at 258 h, which correspond to product yields of 0.37 mg g-1 and 0.75 g g-1, respectively. The present study provided a promising strategy for economically sustainable production of vitamin B12 and propionic acid by P. freudenreichii fermentation using biomass cornstalk as carbon source and expanded bed adsorption bioreactor.Electroanalytic, photometric or fluorometric methods may provide information about the presence of proteolysis in a related sample, but they cannot accurately identify which protease belongs to the proteolytic activity. In other words, they cannot distinguish the proteases according to the differences in their activities. Previous studies on the chymotrypsin and trypsin have shown that the activities of proteases can be distinguished from each other by fluorescence lifetime distributions. In this study, it is aimed to show the sensitivity of the distributional model on the proteolytic activities of the two proteases. For this purpose, the proteolytic activities have been reduced by making covalent conjugation with polyacrylic acid (PAAc) and the effects of the low activities were examined on Bovine Serum Albumin (BSA) which excimer emission character was incorporated into its structure by modification with N-(1-pyrenyl)maleimide. The time-resolved spectrofluorometer was used to collect fluorescence decay data at λ(excimer) = 464 nm, which were analyzed by using Exponential Series Method (ESM) to obtain the changes of lifetime distributions. The results showed a significant decline in the activities. Despite the very low activities, the changes of fluorescence lifetime distributions exhibited remarkable specific differences that proved the sensitivity of ESM analysis.The effect of macro and micronutrients of media components on lipase production by Bacillus sp. VITL8 was investigated using classical as well as statistical methods. Initially, the carbon source, nitrogen source, inducer and metal ions that affect lipase production were selected using the classical approach. Subsequently, selected nutrients along with other key factors (such as pH, agitation rate, gum acacia and tween 80) were investigated using Placket Burman design. Finally, three significant factors, viz., olive oil, peptone and tween 80 were studied using a 22 full factorial central composite design. selleckchem Under optimized condition [6% (v/v) of olive oil, 0.7% peptone, 0.9% tween 80 and 25 h of incubation], the enzyme production was found to be 2.2 times higher with an overall enzyme production of 325.0 ± 1.4 U mL-1. Laboratory scale experiment proved that the enzyme could be utilized for pretreatment of food industry effluent rich in fat and oil (dairy, bakery and poultry). The enzyme was capable of hydrolyzing more than 50% of the initial fat present in all these effluents and enabled the reduction in the levels of biological oxygen demand (BOD) and chemical oxygen demand (COD) of the effluent samples. The study thus reveals the utility of the lipase produced by the halotolerant bacterium Bacillus sp. VITL8 in the pretreatment of industrial effluents contaminated with oil and fat.HighlightsLipase production was enhanced by 2.2-fold using statistical methodsOne of the few reports on lipase production by a halotolerant bacterium, especially by Bacillus sp.Production of 325.0 ± 1.4 U mL-1 lipase within 25 h by a halotolerant bacteriumPretreatment of food industry effluents using Bacillus sp. VITL8 lipaseImprovement in effluent quality within 8 h of treatment.Biting performance is important for feeding, territory defense, and mating in many animals. While maximal bite force is a well-studied trait, other aspects of biting and their variation depending on behavior are rarely considered. Here, we took an innovative approach, where (1) we quantified a novel trait, bite duration in lizards; (2) we examined variation across setups that simulate feeding and antagonistic behavior; and (3) we used F-matrix statistics to investigate how different functional components are optimized for ecological and social demands with respect to individual morphology. Our results did not show differences between the sexes in bite duration, but bite performance varied across experimental setups in males, suggesting a higher functional flexibility in this sex. The investigation of form-function associations revealed that trade-offs, facilitations, and one-to-one relationships are simultaneously involved in the morphological optimization of bite force and duration. Put together, our integrated analysis of two different components of bite performance-force and duration-demonstrates their importance for males in both ecological and social tasks. Our findings also suggest the existence of trade-offs in the morphological optimization of functional components, possibly due to physiological constraints on muscle composition, insertion, and orientation.This study aimed to investigate effects of apple polyphenols (APPs) on myofiber-type transformation in longissimus dorsi muscle of finishing pigs and its mechanism. In this study, 36 healthy castrated Duroc × Landrace × Yorkshire pigs with an average body weight of 71.25 ± 2.40 kg were randomly divided into three treatment groups (control, 0.04% APPs, 0.08% APPs). The experiment lasted for 49 days. Results showed that dietary APP supplementation increased the protein expression of MyHC I and the activities of succinic dehydrogenase and malate dehydrogenase, as well as decreased the protein expression of MyHC IIb and the activity of lactate dehydrogenase, suggesting that APPs promoted muscle fiber-type transformation from fast-twitch to slow-twitch in finishing pigs. We also showed that dietary 0.08% APP supplementation increased the expressions of mitochondrial biogenesis and function-related proteins PGC-1α, Sirt1 and Cytc. In addition, dietary supplementation with 0.08% APPs increased the activities of T-SOD, GSH-PX and CAT and decreased the MDA content.
