Thermal batteries are a type of thermally activated reserve batteries, where the cathode material significantly influences the operating voltage and specific capacity of the battery. In this work, VS-VO has been synthesized through the hydrothermal method and used as the cathode material for thermal batteries. Firstly, the material with the VS crystallinity is obtained at 170 °C and the mass percentages of VS/VO are 63.

Chemical investigation on the 80% EtOH extract of the air dried aerial parts of resulted in the isolation of two new polycyclic polyprenylated derivatives, hypersampines A and B ( and ). The structures of the new compounds were elucidated by spectroscopic data (NMR, IR, and UV) and high resolution mass analysis. The two isolated polyprenylated acylphloroglucinols were tested for cytotoxic activities against 6 pancreatic cell lines.

Article Synopsis
  • Physical activity (PA) is important for combatting obesity, but the best patterns for effectiveness are still unclear, particularly in relation to a novel obesity indicator called the cardiometabolic index (CMI).
  • A study analyzing data from 16,442 U.S. adults found that only those who were regularly active showed a significant reduction in CMI, while those categorized as "weekend warriors" did not see similar benefits.
  • The analysis also suggested that the relationship between PA and CMI was stronger in younger and older adults, those with higher education, and current drinkers, indicating that engaging in over 330 minutes of PA weekly could lead to better CMI outcomes.

Background: Cardiovascular disease is a major complication of diabetes mellitus (DM). Type-2 DM (T2DM) is associated with an increased risk of cardiovascular events and mortality, while serum biomarkers may facilitate the prediction of these outcomes. Early differential diagnosis of T2DM complicated with acute coronary syndrome (ACS) plays an important role in controlling disease progression and improving safety.

Deteriorated age-related bone loss is the hallmarks of skeletal aging. However, how the aging of bone marrow mesenchymal stem cells (BMSCs) and osteoclasts are linked to the bone microstructure degeneration is not yet very clear. In this study, the characteristics of age-related bone loss, distribution patterns of osteoclasts, functional and transcriptomic alterations of BMSCs, hub genes responsible for BMSCs senescence, were analyzed.

The senescence of bone marrow mesenchymal stem cells (BMSCs) is the basis of senile osteoporosis (SOP). Targeting BMSCs senescence is of paramount importance for developing anti-osteoporotic strategy. In this study, we found that protein tyrosine phosphatase 1B (PTP1B), an enzyme responsible for tyrosine dephosphorylation, was significantly upregulated in BMSCs and femurs with advancing chronological age.

Both particulate matter with aerodynamics of less than 2.5 (PM) and ozone are the two main air pollutants in China, which seriously endanger human health. To estimate the adverse impacts of PM and ozone on human health during the implementation of air pollution prevention and control actions in Chengdu, both the generalized additive model and the nonlinear distribution lag model of epidemiology were adopted to explore the exposure-response relationship coefficients of daily ozone 8h maximum concentration average (O), as well as that of PM on disease deaths in Chengdu from 2014 to 2016.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The Spike protein that mediates coronavirus entry into host cells is a major target for COVID-19 vaccines and antibody therapeutics. However, multiple variants of SARS-CoV-2 have emerged, which may potentially compromise vaccine effectiveness.

Article Synopsis
  • MicroRNA-122 (miR-122) is explored as a potential diagnostic biomarker for liver diseases, particularly in patients with HCV-related hepatocellular carcinoma (HCC).
  • A systematic review of six relevant studies, totaling 354 cases and 420 controls, showed promising diagnostic metrics, including a sensitivity of 83% and specificity of 87%.
  • Findings suggest that miR-122 is more effective in identifying HCV-related HCC compared to distinguishing it from cirrhosis, and smaller sample sizes yielded better diagnostic results.

Article Synopsis
  • The study analyzed blood test results from 70 COVID-19 patients in Chongqing, categorizing them into those with and without diarrhea.
  • Significant laboratory indicators like ESR, CRP, and lymphocyte count showed over 50% positivity across the cohort, highlighting their diagnostic value.
  • Notably, while there was no statistical difference in GGT levels between the two groups, all diarrhea patients exhibited decreased GGT, suggesting its potential role in assessing intestinal dysfunction post-infection.

Article Synopsis
  • The study investigates the role of the trehalose biosynthesis pathway in enhancing the pest-control potential of the entomopathogenic fungus Beauveria bassiana through the characterization of a gene called BbTPP.
  • Researchers found that deleting BbTPP eliminated trehalose production, which negatively impacted the fungus's ability to withstand stress and reduced its effectiveness as a biological insecticide.
  • Conversely, over-expressing BbTPP increased trehalose levels, improved stress tolerance, and heightened virulence, suggesting that BbTPP is crucial for both trehalose biosynthesis and the overall pest-control efficacy of this fungus.*

Article Synopsis
  • The study focuses on coordination polymers made from silver (Ag) and a chiral thiol ligand with a specific β-turn structure.
  • These polymers demonstrate supramolecular chirality, meaning they have a unique handedness or orientation on a larger scale.
  • The researchers observed two effects in the system: the majority rules effect (MRE) and the racemate rules effect (RRE), which influence how these chiral structures form and behave.

Cell lysis, where cellular material is released, is the basis for the separation and purification of cell contents, biochemical analysis, and other related experiments. It is also a key step in molecular, real-time, and cancer diagnoses as well as in the drug screening of pathogens. The current methods of lysing cells have several limitations, such as damage to the activity of cellular components, the need for a large number of cell samples, time-consuming processes, and the danger of high voltage.

Background/objective: To compare the curative effect of single-stage and two-stage Fowler-Stephens (F-S) laparoscopic orchidopexy for intraabdominal high testis and explore the appropriate surgical approach.

Methods: We performed a prospective analysis of the clinical data of 28 patients who underwent F-S laparoscopic orchidopexy for intraabdominal high testis in our department from May 2012 to April 2015, including 15 cases of the single-stage F-S operation and 13 cases of the two-stage F-S operation. By comparing the two groups preoperative and postoperative (6 months) clinical data of testicular position, testicular volume, and sex hormone levels [testosterone (T), follicle stimulating hormone (FSH), and estradiol (E)], we analyzed the difference in efficacy between the two procedures.

Selective synthesis of 4-(sulfonyl)-methyl-1H-pyrazoles and (E)-4,5-dihydro-1H-pyrazoles from N-allenic sulfonylhydrazones with sulfonyl group migrations has been developed. A key feature of these reactions is that the migrations of the sulfonyl groups to different positions can be controlled by changing the Lewis acids.
