The regulatory role of CDK4/6 inhibitors in tumor immunity and the potential value of tumor immunotherapy (Review).

Cyclin‑dependent kinase (CDK)4/6 inhibitors regulate the cell cycle by binding to CDK4/6, thus exerting an inhibitory effect, and they have a notable impact on tumor immunity. CDK4/6 inhibitors have been demonstrated to modulate the immune microenvironment by affecting immune cells and immune escape phenomena in the tumor microenvironment. T cells, natural killer cells and macrophages are all regulated by CDK4/6 inhibitors, thereby acting on cancer cells.

Direct pharmacological AMPK activation inhibits mucosal SARS-CoV-2 infection by reducing lipid metabolism, restoring autophagy flux and the type I IFN response.

Unlabelled: AMP-activated protein kinase (AMPK) plays a central role in regulating cell energy balance. When activated, AMPK suppresses energy-consuming pathways, such as lipid and protein synthesis, while increasing nutrient availability through the activation of autophagy. These pathways downstream of AMPK activation contribute to SARS-CoV-2 infection, which hijacks autophagy and accumulates lipid droplets in viral factories to support viral replication.

Biomimetic Alumina Film for Passive Daytime Radiative Cooling.

Passive daytime radiative cooling is receiving more and more attention as a cooling method that does not consume energy to cool objects. However, most radiative cooling materials require the mixing of multiple particles, which increases the manufacturing process requirements. Most radiative cooling materials are susceptible to outdoor abrasion, pollution, and UV exposure, which leads to decreased performance.

Microbial-induced reassembly of phosphate sol: New insight into the removal and fixation of divalent manganese in natural aquatic environment.

The commonly used precipitation method struggles to effectively remove low-concentration heavy metals from water. Herein, we demonstrate that the formation of non-settleable phosphate sols at a low low-concentration is the main reason by using phosphate precipitation as an example and report a new method called microbial-induced reassembly (MIR) of the phosphate sols for the removal and fixation of divalent manganese (Mn(II)) from low-concentration wastewater under neutral conditions. Under the induction of microorganisms, the Mn(PO) sols formed in low Mn(II) concentration could be reassembled into larger and flower-like precipitates with good settleability, allowing for the removal and fixation of low-concentration Mn(II) through natural settlement.

A novel role of AIM2 inflammasome-mediated pyroptosis in radiofrequency ablation of hepatocellular carcinoma.

Introduction And Objectives: The absence of melanoma 2 (AIM2) protein triggers the activation of the inflammasome cascade. It is unclear whether AIM2 plays a role in hepatocellular carcinoma (HCC) and radiofrequency ablation (RFA), which uses radiofrequency waves to treat tumors. In this study, we investigated if RFA could induce pyroptosis, also called cell inflammatory necrosis, in HCC through AIM2-inflammasome signaling in vivo and in vitro.

Trends of gastric cancer burdens attributable to risk factors in China from 2000 to 2050.

Background: The incidence of gastric cancer (GC) decreased in past decades, which was thought largely attributable to risk factors control, yet China still accounts for 44% of global GC burdens. We aimed to estimate changing trajectories of proportions of GC burdens attributable to modifiable risk factors from 2000 to 2050 in China, to inform future targeted preventive strategies.

Methods: The incidence and new cases of GC were predicted to 2050 using Bayesian age-period-cohort model based on incidence data by anatomical subsites drawn from 682 cancer registries from National Central Cancer Registry.

A systematic review and meta-analysis on the relative and attributable risk of infection and cardia and non-cardia gastric cancer.

Introduction: This study aimed to update the association between Helicobacter pylori (H. pylori) infection and gastric cancer (GC).

Methods: We searched PubMed, Embase, and Cochrane Library from 1990 to December 2021 to identify prospective studies.

Protocol to detect infectious SARS-CoV-2 at low levels using in situ hybridization techniques.

Low and persistent levels of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA/protein/virus can be detected in clinical samples months after infection, possibly related to the emergence of SARS-CoV-2 variants or development of long coronavirus disease. Here, we present a protocol to detect low levels of viral RNA together with protein using flow cytometry and microscopy. We describe steps for cell infection with SARS-CoV-2 and quantification by fluorescence in situ hybridization-flow cytometry.

Iridoid-glycoside isolation and purification from Premna fulva leaves.

Premna fulva Craib, rich in iridoid glycosides, is widely used to treat periarthritis, osteoproliferation, pain, and other diseases. However, no studies have reported effective purification methods for obtaining iridoid glycosides as active materials. This paper describes an efficient strategy for separating iridoid glycosides from Premna fulva leaves using high-speed counter-current chromatography and preparative high-performance liquid chromatography.

Extracellular RNA in melanoma: Advances, challenges, and opportunities.

Melanoma, a malignant mass lesion that originates in melanocytes and has a high rate of malignancy, metastasis, and mortality, is defined by these characteristics. Malignant melanoma is a kind of highly malignant tumor that produces melanin and has a high mortality rate. Its incidence accounts for 1%-3% of all malignant tumors and shows an obvious upward trend.

Bionic research on scales for drag reduction.

Drag reduction is a key problem in marine vehicles and fluid transportation industries. Reducing drag strategies and mechanisms need to be further investigated. To explore a bionic approach for reducing flow resistance, experimental and numerical simulation research was conducted to study the drag reduction characteristics of the surface microstructure.

Rational design to enhance the catalytic activity of 2-deoxy-D-ribose-5-phosphate aldolase from Pseudomonas syringae pv. syringae B728a.

The 2-Deoxy-d-ribose-5-phosphate aldolase (DERA) enzyme in psychrophilic bacteria has gradually attracted the attention of researchers. A novel gene, deoC (681 bp), encoding DERA, was identified in Pseudomonas syringae pv. syringae B728a, recombinantly expressed in E.
