With the rapid development of the Internet of Things, 5G, and communication technologies, the growth of various types of data has shown an exponential trend. Edge computing technology provides users with almost unlimited computing power through a large number of high-performance servers in the data center. It is one of the important solutions for big data analysis and processing. Volleyball has caused a great wave in China as early as the 1960s, but people pay little attention to the physical quality of volleyball players. At the same time, in the medical field, it is difficult to give a clear value to the athlete’s protein requirement. Therefore, this article aims to observe the specific values of protein metabolism in volleyball at different levels of protein nutrition. By designing controlled experiments, then these rats under three nutrient levels of protein were observed and protein metabolism was analyzed after volleyball. The results of the study show that volleyball exercise can reduce the nitrogen balance and gastrocnemius nitrogen content. The nitrogen balance of the 17% group decreased from 388 mg/day before exercise to 336 mg/day, and the gastrocnemius nitrogen content decreased by up to 5.2%; serum urea nitrogen concentration and liver nitrogen content are increased, indicating the enhancement of protein catabolism. Different protein nutrition levels have different effects on protein metabolism during volleyball. The protein intake level of 17% is more conducive to resist the protein decomposition caused by volleyball. It can be seen that, based on edge computing technology, the influence factors of protein nutrition level on protein metabolism during volleyball sports can be well explored, and the research results are also very valuable.

Recently, there has been a significant increase in interest in research on hypertension (HT), primarily due to its high prevalence. The interest in studying this problem is also exacerbated by the often insufficient effectiveness of existing treatments. The effect of concomitant pathologies on HT, in particular non-alcoholic fatty liver disease (NAFLD), remains poorly understood. The aim of the study – to evaluate the changes in the serum albumin binding function (SABF) and its relationship with the biochemical parameters of the blood when HT and HT combined with NAFLD and to suggest ways of medical correction of the detected disorders. Material and methods. 76 individuals with stage 2 HT with degree 2–3 arterial hypertension were examined. They were divided into two groups. Group 1 included 28 patients with HT without concomitant diseases who received basic hypertension therapy, and group 2 included patients with concomitant NAFLD. The latter in turn was divided into two subgroups: 2a – 27 patients who in addition to basic HT therapy received additional Antral hepatoprotector 200 mg three times a day for 2 months, and 2b – 21 patients who received only basic HT therapy. All of them underwent a standard clinical examination, as well as SABF, protein fractions, and liver function indicators. The comparison group consisted of 25 healthy individuals, comparable in age and sex. Results and Discussion. Patients in group 1 showed moderate changes in the functional state of the liver, but they did not exceed the norm, patients in group 2 – a significant decrease in SABF, as well as protein metabolism (decrease in total protein, albumin, albumin-globulin ratio and increase globulins) and liver function (increased activity of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltranspeptidase, thymol levels, alkaline phosphatase and total bilirubin). After treatment, the majority of patients in subgroup 2 had a statistically significant increase in SABF and a quantitative improvement in protein fractions and functional state of the liver. In subgroup 2-b, where hepatoprotective treatment was not performed, significant changes in most indicators did not occur. The results may be related to the positive effect of the drug on the liver, which leads to improved functional status of hepatocytes and their protein-synthesizing ability. In subgroup 2 b, where hepatoprotective treatment was not performed, significant changes in most indicators did not occur. The results may be related to the positive effect of the drug on the liver leading to improved functional status of hepatocytes and their protein-synthesizing ability. Conclusions. Changes of the functional state of the liver are observed when HT without concomitant pathology. HT with NAFLD is accompanied by a significant decrease in SABF, changes in protein metabolism and the functional state of the liver. Prescribing Antral to such patients helps to increase SABF, normalize protein metabolism and improve the functional state of the liver.

Dietary and endogenous protein that become available for the microbiota in the hindgut can be metabolized via different routes. They can become building blocks for the microbial cells or enter different catabolic pathways. Protein degradation via fermentation pathways is seen as a non-preferred route as it results in the formation and release of metabolites that can interfere with biological systems in the host and can have deleterious outcomes. Reducing protein fermentation and guiding the metabolism towards less toxic end-products might be possible targets for improving host health. To do so, more knowledge on factors manipulating the process of microbial protein metabolism, including on substrate availability, microbial composition and segmental differences in the hindgut, is required.

AbstractThe schweinfurthin family of natural compounds exhibit a unique and potent differential cytotoxicity against a number of cancer cell lines and may reduce tumor growth in vivo. In some cell lines, such as SF-295 glioma cells, schweinfurthins elicit cytotoxicity at nanomolar concentrations. However, other cell lines, like A549 lung cancer cells, are resistant to schweinfurthin treatment up to micromolar concentrations. At this time, the precise mechanism of action and target for these compounds is unknown. Here, we employ RNA sequencing of cells treated with 50 nM schweinfurthin analog TTI-3066 for 6 and 24 h to elucidate potential mechanisms and pathways which may contribute to schweinfurthin sensitivity and resistance. The data was analyzed via an interaction model to observe differential behaviors between sensitive SF-295 and resistant A549 cell lines. We show that metabolic and stress-response pathways were differentially regulated in the sensitive SF-295 cell line as compared with the resistant A549 cell line. In contrast, A549 cell had significant alterations in response genes involved in translation and protein metabolism. Overall, there was a significant interaction effect for translational proteins, RNA metabolism, protein metabolism, and metabolic genes. Members of the Hedgehog pathway were differentially regulated in the resistant A549 cell line at both early and late time points, suggesting a potential mechanism of resistance. Indeed, when cotreated with the Smoothened inhibitor cyclopamine, A549 cells became more sensitive to schweinfurthin treatment. This study therefore identifies a key interplay with the Hedgehog pathway that modulates sensitivity to the schweinfurthin class of compounds.

Type 2 Diabetes Mellitus (T2D) is defined as a chronic condition caused by beta cell loss and/or dysfunction and insulin resistance (IR). (1) Background: The discovering of novel biomarkers capable of identifying T2D and other metabolic disorders associated with IR in a timely and accurate way is critical. In this review, 2-hydroxybutyric acid (2HB) is presented as that upheaval biomarker with an unexplored potential ahead. Due to the activation of other metabolic pathways during IR, 2HB is synthesized as a coproduct of protein metabolism, being the progression of IR intrinsically related to the increasing of 2HB levels. Hence, the focus of this review will be on the 2HB metabolite and its involvement in glucose homeostasis. (2) Methods: A literature review was conducted, which comprised an examination of publications from different databases that had been published over the previous ten years. (3) Results: A total of 19 articles fulfilled the intended set of criteria. The use of 2HB as an early indicator of IR was separated into subjects based on the number of analytes examined simultaneously. In terms of the association between 2HB and IR, it has been established that increasing 2HB levels can predict the development of IR. (4) Conclusions: Thus, 2HB has demonstrated considerable promise as a clinical monitoring molecule, not only as an IR biomarker, but also for disease follow-up throughout IR treatment.

The main role in maintaining the functioning of the body, its growth, and development belongs to protein. It is involved in the formation of the muscular skeleton and is s part of enzymes, neurotransmitters, hormones. The effect of the autonomic nervous system on total protein metabolism has not been sufficiently studied. It is known that the autonomic nervous system is a structure that is responsible for the homeostasis and stability of the whole organism. It participates in the regulation of the heart, endocrine and external secretion glands, gastrointestinal tract, excretory organs, and more. In our studies, it was found that in chickens of Cobb 500 strain with different tones of the autonomic nervous system during the growing period from the 35th to the 60th day, different contents of total protein, albumin, and globulins were observed and different body weights were recorded. Vagotonic chickens showed the lowest protein metabolism at the age of 35 and 45 days (P ˂ 0.05–0.001) compared with sympathicotonics and normotonics, which tended to increase between 35 and 60 days of rearing compared with other groups of birds, where the studied protein fractions on the contrary decreased. Correlations between total protein, albumin, and bird body weight had a high linear relationship in all groups of chickens (P ˂ 0.05–0.001) and a negative relationship between the 45th and 60th days of rearing in sympathicotonics and normotonics. In birds with a predominance of parasympathetic tone of the autonomic nervous system, this correlation maintained its direction with high reliability (P ˂ 0.05) between body weight and total protein on the 60th day of rearing.

AbstractDiet is a key factor influencing gut microbiota (GM) composition and functions, which in turn affect host health. Among dietary regimens, time-restricted (TR) feeding has been associated to numerous health benefits. The impact of TR feeding on the GM composition has been mostly explored by means of metagenomic sequencing. To date, however, little is known about the modulation of GM functions by this dietary regimen. Here, we analyzed the effects of TR feeding on GM functions by evaluating protein expression changes in a rat model through a metaproteomic approach. We observed that TR feeding has a relevant impact on GM functions, specifically leading to an increased abundance of several enzymes involved in carbohydrate and protein metabolism and expressed by Lactobacillus spp. and Akkermansia muciniphila. Taken together, these results contribute to deepening our knowledge about the key relationship between diet, GM, and health.

Abstract The research is devoted to the study of the influence of the modern antioxidant of the flavonoid group ‘Dihydroquercetin’ as part of the feed combination on the hematological profile and biochemical parameters of the blood of broiler chickens of the KOBB-500 cross. The content of hemoglobin and erythrocytes in the blood of broilers receiving dihydroquercetin increased, which indicates an increase in the intensity of redox processes in the body. The number of leukocytes in all groups was normal, but in the experimental groups their decrease was noted, which indicates the therapeutic and immunostimulating effect of the drug. Evaluation of protein metabolism by the content of total protein and the fraction of albumin in the blood serum showed its positive dynamics within the normal physiological values, which characterizes an increase in the intensity of assimilation processes in the bird’s body. The metabolism of carbohydrates was assessed by the content of glucose in it, and a decrease in its level indicates its increased consumption as an energy component for metabolic processes associated with intensive growth of chickens. An increase in the activity of alkaline phosphatase by 1.3-1.8 times is associated with the active growth of chickens.
