Multitarget antibacterial drugs: An effective strategy to combat bacterial resistance.

The rise of antibiotic resistance and the decrease in the discovery of new antibiotics have caused a global health crisis. Of particular concern is the fact that despite efforts to develop new antibiotics, drug discovery is unable to keep up with the rapid development of resistance. This ongoing crisis highlights the fact that single-target drugs may not always exhibit satisfactory therapeutic effects and are prone to target mutations and resistance due to the complexity of bacterial mechanisms.

A synthetic antibiotic class with a deeply-optimized design for overcoming bacterial resistance.

The lack of new drugs that are effective against antibiotic-resistant bacteria has caused increasing concern in global public health. Based on this study, we report development of a modified antimicrobial drug through structure-based drug design (SBDD) and modular synthesis. The optimal modified compound, F8, was identified, which demonstrated in vitro and in vivo broad-spectrum antibacterial activity against drug-resistant bacteria and effectively mitigated the development of resistance.

The potential of CD38 protein as a target for autoimmune diseases.

Cluster of differentiation 38 (CD38) is a multifunctional cell surface protein involved in nicotinamide adenine dinucleotide (NAD) homeostasis in types of cells and tissues, which can be found in many immune cells and non-immune cells. Previous studies have shown that CD38 plays an important role in regulating innate immunity. Recently, many studies have revealed the importance of CD38 in autoimmune diseases, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS), type 1 diabetes (T1D) and inflammatory bowel disease, among others.

Contamination of harbouring various clinically important antimicrobial resistance genes in retail meat and aquatic products from food markets in China.

is an opportunistic pathogen frequently associated with nosocomial infection and food poisoning cases. Contamination of in retail meat products may be important transmission routes for human infection with . In this study a total of 89 strains were isolated from 347 samples in 14 food markets in China and subjected to whole-genome sequencing.

Decomposing manufacturing CO emission changes: An improved production-theoretical decomposition analysis based on industrial linkage theory.

Identifying key drivers of manufacturing CO emissions is critical to carbon reduction practices. For manufacturing, CO emissions are mainly determined by production capacity and production scale. However, traditional production-theoretical decomposition analysis (PDA) fails to consider production-scale-related drivers.

Study on the Water Quality Characteristics of the Baoan Lake Basin in China under Different Land Use and Landscape Pattern Distributions.

Land use and landscape pattern highly affect water quality. Their relationship can assist in land-use management and improve land-use efficiency. In this study, a water quality survey of rivers and lakes was performed in 2020 to analyze the effects of land use and the landscape pattern on the water quality of the rivers and lakes in the Baoan Lake basin and is expected to provide a reference for land use planning.

High doses of baicalin induces kidney injury and fibrosis through regulating TGF-β/Smad signaling pathway.

Baicalin is a major flavonoid compound purified from Scutellariae radix, which has been described as an herb in the Chinese Pharmacopoeia. Previous studies have suggested baicalin possessed extensive anti-inflammatory, anti-cancer, anti-viral properties. However, up to known, there have been no reports of safety and toxicity in the rats following oral administration of baicalin.

[Advances in mechanism of Escherichia coli carbon catabolite repression].

Bacteria often sequentially utilize coexisting carbohydrates in environment and firstly select the one (frequently glucose) easiest to metabolize. This phenomenon is known as carbon catabolite repression (CCR). In existing Chinese teaching materials of molecular biology and related courses, unclear or even wrong interpretations are given about CCR mechanism.
