Asthma is a chronic airway inflammatory disease of the airways characterized by the involvement of numerous inflammatory cells and factors. Therefore, targeting airway inflammation is one of the crucial strategies for developing novel drugs in the treatment of asthma. Phosphoinositide 3-kinase gamma (PI3Kγ) has been demonstrated to have a significant impact on inflammation and immune responses, thus emerging as a promising therapeutic target for airway inflammatory disease, including asthma.

Background: Mitochondrial transcription elongation factor (TEFM) is a recently discovered factor involved in mitochondrial DNA replication and transcription. Previous studies have reported that abnormal TEFM expression can disrupt the assembly of mitochondrial respiratory chain and thus mitochondrial function. However, the role of TEFM on Uterine corpus endometrial carcinoma (UCEC) progression remains unclear.

To investigate the structural and functional similarities of microbial communities in burnt-sweetness alcoholized tobacco as a function of distance from the equator and their effects on tobacco quality, we sampled alcoholized tobacco from Chenzhou, Hunan Province, China and from Brazil and Zimbabwe, which are also burnt-sweetness-type tobacco producing regions, and performed high-throughput sequencing of tobacco bacterial and fungal communities along with an analysis of the main chemical constituents of the tobacco to analyze differences in the quality of the tobacco and similarities in the structure of the microbial communities. The total nitrogen, nicotine and starch contents of Chenzhou tobacco were greater than those of Brazilian and Zimbabwean tobacco, and the total sugar and reducing sugar contents of the Brazilian and Zimbabwean tobacco were greater than those of the Chenzhou tobacco (P < 0.05).

Propolis is a natural immunomodulator with anticancer activity. This study investigated the immunomodulatory mechanism and anti-tumor activity of supercritical CO extracts of propolis (SEP) in tumor-bearing immunosuppression mice. We used cyclophosphamide (CTX) to construct the immunosuppressive mice model and then inoculated them with CT26 cells to build the CT26 tumor-bearing immunosuppression mice model.

Background: Co-formulated dolutegravir and lamivudine (DTG/3TC) is recommended as the first-line antiretroviral therapy (ART); however, the data on the viral decay in seminal plasma (SP) and blood plasma (BP), as well as changes in inflammatory biomarkers in BP, remain limited among antiretroviral-naïve people with HIV (PWH) receiving DTG/3TC. A prospective observational cohort study was conducted to compare the impact of DTG/3TC vs. bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) on viral decay kinetics and changes in inflammatory biomarkers in antiretroviral-naïve PWH.

Phosphate (Pi) has an important influence on the water environment and physiological processes. Therefore, developing fluorescent probe for quantitative detection of Pi is crucial for water environment monitoring and human health assessment. This work designed a dual-emission ratio nano-fluorescent probe GCDs/Eu-BDC based on europium-based metal-organic frameworks (Eu-MOFs) and blue carbon dots (GCDs) for multicolor fluorescence detection of Pi.

The uranium recovery from high concentration fluorine-containing uranium wastewater is a desired research target in the field of environmental radiochemistry but is very challenging due to the formation of stable uranium fluoride complexes that are quite difficult to extract. By employing surface defect engineering and interfacial heterostructure design, we present here the rational design of an efficient photocatalyst (Ag/WO) for U(VI) uptake from fluorine-containing uranium wastewater without any sacrificial agents. The defect-rich surface of Ag/WO facilitates confined adsorption of uranium, while the introduction of Ag nanoparticles enables both efficient electron-hole separation and a plasmon effect upon light irradiation.
