Small urban lakes are recognized as significant sources of nitrous oxide (NO) to the atmosphere. Despite the crucial role of aquatic plants in landscape construction and pollutant removal within urban lakes, the modulation of NO emission dynamics and associated mechanisms by these plants remains elusive. This study investigated the NO concentrations and fluxes from aquatic habitats covered with seven species of aquatic plants in a small urban lake, and estimated the contribution of plant-mediated NO emissions.

A post-transition state surface intersection (PTSSI) between radical and zwitterionic states that causes a bifurcation in the reaction pathway was discovered through density functional theory calculations on potential energy surfaces and ab initio molecular dynamics simulations of cycloadditions between a bicyclobutane and a triazolinedione (BCB-TAD). It was predicted that changes to the solvent polarity would enable control over the dynamic selectivity in this system; indeed, experimental evidence supported this prediction. This work not only provides new insights into an unusual type of post-transition state bifurcation, but also demonstrates how the nonstatistical dynamic effects that control selectivity for such reactions can be manipulated rationally to increase the yields of synthetically useful reactions.

CO capture and separation from natural and fuel gas are important industrial issues that refer to the control of CO emissions and the purification of target gases. Here, a novel non-planar g-CN monolayer that could be synthesized the supramolecular self-assembly strategy was identified using DFT calculations. The cohesive energy, phonon spectrum, BOMD, and mechanical stability criteria confirm the stability of the g-CN monolayer.

Article Synopsis
  • Small lakes release significant amounts of carbon monoxide (CO) and methane (CH), yet their emissions dynamics, particularly in urban areas, are not well understood.
  • The study examined 33 small lakes to understand how human activities, like urbanization and aquaculture, affect CO and CH emissions, finding that urban and aquaculture lakes have much higher emissions than those used for irrigation or drinking water.
  • The research highlighted that nutrient loads and sediment composition are key drivers in these emissions, suggesting that human impact on lakes increases their greenhouse gas output, which complicates predictions about these emissions.

Background: Rheumatoid arthritis (RA) is partially affected by the integrity of the intestinal barrier. Licorice (GC), a medicinal and food-related herb, exhibits potent anti-inflammatory activity; however, studies on its mechanisms of action in RA are limited.

Method: Using a bovine type-II collagen-induced arthritis rat model, this study examined how GC influences the gut-joint axis to decrease RA.

  • - The study explores the role of platelet-to-lymphocyte ratio (PLR) as a potential serum biomarker for assessing prognosis in rectal cancer patients, highlighting its link to tumor inflammation and growth.
  • - A literature review analyzed 23 studies with 7,577 patients, finding a significant correlation between high PLR and worse overall survival (OS), but no strong link to disease-free survival (DFS).
  • - The results suggest that PLR can be a useful clinical predictor for OS in rectal cancer patients post-surgery, aiding in personalized treatment planning, while its effectiveness for DFS remains uncertain.

Aims: We aimed to determine the concentrations of synovial vancomycin and meropenem in patients treated by single-stage revision combined with intra-articular infusion following periprosthetic joint infection (PJI), thereby validating this drug delivery approach.

Methods: We included 14 patients with PJI as noted in their medical records between November 2021 and August 2022, comprising eight hip and seven knee joint infections, with one patient experiencing bilateral knee infections. The patients underwent single-stage revision surgery, followed by intra-articular infusion of vancomycin and meropenem (50,000 µg/ml).

Density functional theory computations were used to model the formation and rearrangement of the barbaralyl cation (CH ). Two highly delocalized minima were located for CH , one of symmetry and the other of symmetry, with the former having lower energy. Quantum chemistry-based NMR predictions affirm that the lower energy structure is the best match with experimental spectra.

Article Synopsis
  • An electrochemical aptasensor was developed for rapid detection of zearalenone (ZEN) using CoO/MoS/Au nanocomposites combined with a hybrid chain reaction (HCR) method.
  • The sensor works by immobilizing ZEN-specific DNA on a modified electrode, which triggers the HCR only in the presence of ZEN, leading to the production of a double-stranded DNA structure.
  • This system allows for sensitive detection of ZEN, with a wide detection range and a low limit of detection, making it highly applicable in food safety, medical testing, and drug analysis.

Contributions from quantum mechanical tunneling to the rates of several radical coupling reactions between carbon sp centers used as key steps in natural product total syntheses were computed using density functional theory. Contributions ranging from ∼15-52% from tunneling were predicted at room temperature, thereby indicating that tunneling plays an important role in the rates of these reactions and should perhaps be considered when designing complex synthetic schemes.
