The preventative effects of metabolites against LPS-induced sepsis.

Introduction: Sepsis is a syndrome of organ dysfunction caused by a dysregulated host response to infection and septic shock. Currently, antibiotic therapy is the standard treatment for sepsis, but it can lead to drug resistance. The disturbance of the gut microbiota which is affected by sepsis could lead to the development of organ failure.

A pilot study on oral microbiome in electronic cigarettes consumers versus traditional cigarettes smokers.

Oral microorganisms are closely related to oral health, the occurrence of some oral diseases is associated with changes in the oral microbiota, and many studies have demonstrated that traditional smoking can affect the oral microbial community. However, due to the short time since the emergence of e-cigarettes, fewer studies are comparing oral microorganisms for users of e-cigarettes versus cigarettes. We collected saliva from 40 non-smokers (NS), 46 traditional cigarette smokers (TS), and 27 e-cigarette consumers (EC), aged between 18 and 35 years.

Urea-Straw-Starch Fertilizer with Tunable Water- and Nutrient-Retaining Properties Assisted by High-Energy Electron-Beam Irradiation.

A novel type of water- and nutrient-retaining fertilizer (WNRF) was prepared by mixing, melting, and extruding high-energy electron-beam (HEEB)-irradiated corn straw, urea, and starch. HEEB irradiation technique effectively killed pathogenic microorganisms in straw and further improved the adsorption and binding capacity of straw to urea and water. Compared to nonirradiated HEEB samples, the optimal WNRF improved the water retention rate by 25.

Tamarind Seed Polysaccharide Hydrolysate Ameliorates Dextran Sulfate Sodium-Induced Ulcerative Colitis via Regulating the Gut Microbiota.

A comparative assessment of e-cigarette aerosol extracts and tobacco cigarette smoke extracts on endothelial cell inflammation response.

With the development of the times, electronic cigarettes (e-cigarettes) are being received by more and more people. We compared the different effects of e-cigarettes and tobacco cigarettes on human umbilical vein endothelial cells (HUVECs) treated with the typical e-cigarette aerosol extracts (ECA) and cigarette smoking extracts (CS) sourced from commercial retail stores. HUVECs were treated with different kinds of ECA or CS with different nicotinic concentrations (0.

Effects of brassinosteroids on cancer cells: A review.

Brassinolide is a new type of steroidal hormone with strong activities, which is well known as an efficient and low-toxicity plant growth regulator for a long time. Because steroidal hormones have a wide application prospect, brassinosteroids have been gradually explored in pharmacology and animal cells in recent decades. Brassinolide could effectively reverse the resistance of human T lymphoblastoid cell line CCRF-VCR 1000 by inhibiting the effusion of drug transported by P-glycoprotein.

Cistanche promotes the adipogenesis of 3T3-L1 preadipocytes.

Cistanche deserticola Ma (cistanche) is a traditional herb with a wide range of therapeutic properties. However, no evidence of cistanche's effect on adipogenesis has been found. The effect of cistanche that promotes the adipogenesis of 3T3-L1 preadipocytes was proved by using MTT spectrophotometry, Nile Red staining, Oil Red O staining and transcriptome sequencing technology.

Treatment and high value utilization of glutamic acid wastewater.

Glutamate wastewater has a high yield in the world and is difficult to be treated due to its high acidity, high COD (chemical oxygen demand, reflecting the pollution degree of reduced substances in the water) and high ammonia nitrogen characteristics. In this study, M 2020051 was used to treat organic wastewater to ferment polyglutamic acid, which reduced the pollution of industrial wastewater and produced polyglutamic acid at a low cost. Firstly, a strain with high salt tolerance and high polyglutamic acid production was isolated from saline soil, and the mechanism of salt tolerance and polyglutamic acid production were also analyzed.
