At present, the mechanism difference between tetragonal BiVO (t-BiVO) and monoclinic BiVO (m-BiVO) coupled peroxymonosulfate (PMS) to realize photocatalysis is still unclear. In this study, m-BiVO and t-BiVO were obtained by adjusting the bismuth-vanadium ratio in the precursor solution (Bi:V = 3:1; 1:1; 1:2 and 1:3). The results of photocatalytic experiments showed that both t-BiVO and m-BiVO had certain activation effects on PMS, and the prepared monoclinic B1V2 has the strongest photocatalytic performance.

Aims: This study applied exercise stress echocardiography (ESE) to identify risk factors associated with exercise intolerance in patients with chronic coronary syndrome (CCS).

Methods And Results: 90 CCS patients underwent a cardiopulmonary exercise test and ESE, assessing exercise capacity, left ventricular systolic and diastolic function, and systolic reserve. The patients were divided into two groups according to the percentage of predicted oxygen consumption (VO) at peak (≥85%, normal exercise tolerance group; <85%, exercise intolerant group).

Surface enhanced Raman scattering (SERS) has been proved an effective analytical technique due to its high sensitivity, however, how to identify and extract useful information from raw SERS spectra is still a problem that needs to be resolved. In this work, a composite SERS substrate was prepared by encapsulating Ag nanoparticles within dialdehyde starch (Ag@CDS) to obtain dense "hot spot", and then a novel spectral preprocessing algorithm namely lineshape correction algorithm (LCA) was developed to separate the characteristic peaks of analytes from the original SERS spectra. Based on Ag@CDS and LCA, thiram residues in different beverages were quantitatively detected using back propagation (BP) neural network regression model.

Article Synopsis
  • - The study reveals that Enzyme-IIA (EIIA) links glucose sugar uptake with a regulatory system affecting antibiotic resistance, where phosphorylated EIIA increases cAMP-Crp activity, leading to cell death through reactive oxygen species (ROS) accumulation.
  • - Mannitol, unlike other sugars that require EIIA for uptake, has been shown to reduce the effectiveness of antibiotics without changing their minimum inhibitory concentration, indicating it promotes antibiotic tolerance by inhibiting cAMP-Crp action.
  • - This research highlights that other non-glucose carbon sources like mannose and sorbitol can also induce similar antibiotic tolerance through a mechanism that lowers ROS activity, posing challenges for effective infection treatment.

Malignant fibroblasts (MFs) are widely present in various diseases and are characterized by connective tissue proliferation; these cells act as a physical barrier that severely limits drug delivery and affects disease outcomes. Based on this, we constructed the smart, integrated, theranostic, targeted lipid nanoprobe HMME-RG3@PFH to overcome the bottleneck in the early diagnosis and treatment of MF-related diseases. The protein glucose transporter protein 1 (GLUT-1) is overexpressed on MFs, and its ideal substrate, ginsenoside RG3 (RG3), significantly enhances the targeted uptake of HMME-RG3@PFH by MFs in a hypoxic environment and endows the nanomaterial with stealthiness to prolong its circulation.

Bicycle crashes at intersection areas are posed a worrying traffic safety issue, and one of the main reasons for bicycle crashes is failing to avoid conflicts with motor vehicles and other bicycles. Clearly, cyclists are more exposed to risk if they perform a direct left turn (DLT) being mixed with left-turning vehicle under a left-turn phase. Owing to the lack of exposure data, the detection of DLT event and the mechanism behind the risky riding behavior have yet to be discovered.

The tightly bonded structure of polybenzimidazole (PBI) membrane is the origin of its poor proton conductivity, which severely hinders achieving a cost-effective membrane for vanadium redox flow battery (VRFB). It desires a strategy to relax the membrane structure to significantly improve the proton conductivity and maintain its structure stability. Therefore, this work proposes a novel strategy through regulating molecular interactions within PBI membrane to loosen up the structure of PBI membrane and dramatically enhance the proton conductivity.

  • Lipid levels may be linked to a reduced risk of multiple myeloma (MM), with a study using meta-analysis and Mendelian randomization to explore this association.
  • Observational data indicated that higher levels of LDL, HDL, total cholesterol, and triglycerides correlate with a lower MM risk, while triglycerides specifically showed a potential causal link independent of body mass index (BMI).
  • Findings suggest that targeting higher lipid levels, particularly triglycerides, could provide new treatment strategies for those at risk for MM.

Regulating the coordination environment of Fe-N sites is an efficient but challenging approach for promoting the intrinsic catalytic activity of single-atom Fe/N-codoped carbon (Fe-N-C) toward the oxygen reduction reaction (ORR). Herein, low-coordination Fe-N sites coupled with carbon vacancies (Fe-N/C) are directionally constructed in Fe-N-C via pyrolysis of a metal-organic framework (MOF) precursor with N-Zn-O-Fe moieties, which are delicately prefabricated by chemically anchoring Fe onto a HO-etching induced linker-missing Zn-N site in the MOF precursor. The optimized Fe-N-C with the Fe-N/C sites displays a high ORR half-wave potential of 0.
