Antimicrobial Resistance Genes in from Artificial Water Systems: Findings from a Two-Year Study.

Background: species are the causative agent of Legionnaires' disease and, as ubiquitous waterborne bacteria, are prone to antimicrobial resistance gene (ARG) acquisition and dissemination due to the antimicrobial contamination of natural environments. Given the potential health risks associated with ARGs, it is crucial to assess their presence in the population.

Methods: The ARGs and were detected in 348 samples, isolates, and DNA extracts using conventional PCR.

Impact of inter-city interactions on disease scaling.

Inter-city interactions are critical for the transmission of infectious diseases, yet their effects on the scaling of disease cases remain largely underexplored. Here, we use the commuting network as a proxy for inter-city interactions, integrating it with a general scaling framework to describe the incidence of seven infectious diseases across Brazilian cities as a function of population size and the number of commuters. Our models significantly outperform traditional urban scaling approaches, revealing that the relationship between disease cases and a combination of population and commuters varies across diseases and is influenced by both factors.

IVF with frozen-thawed sperm after prolonged capacitation yields comparable results to ICSI in horses: A morphokinetics study.

Intracytoplasmic sperm injection (ICSI) is the current clinical practice for the in vitro production of equine embryos. The use of conventional fertilization methods such as in vitro fertilization (IVF), has historically been associated with poor success in horses. However, recent improvements have led to better outcomes with IVF, though only when using fresh semen, which limits its use in clinical practice.

Pentacyclic Triterpenoid Content in Cranberry Raw Materials and Products.

Cranberry fruit extracts have been shown to inhibit expression of pro-inflammatory cytokines in THP-1 cells and reduce colonic tumor burden and tissue inflammation in a mouse model of colitis. These activities are attributed to both the triterpenoid and polyphenol constituents of the fruit. The pentacyclic triterpenoids ursolic acid (UA), oleanolic acid (OA), corosolic acid (CA), maslinic acid (MA), and esters of UA and OA occur in the waxy layer of cranberry peel, and their content in cranberry products is likely to vary with the fruit source and processing methods.

Biochar improves growth and physiology of Swietenia macrophylla king in contaminated soil by copper.

The production of açaí seed waste from the commercial and extractive exploitation of the Euterpe oleraceae palm tree is a serious problem that contributes to environmental contamination and production of greenhouse gases, a fact that suggests the need for an environmentally correct destination for this waste produced on a large scale. To this end, this study was conducted to evaluate the potential of acaí seed biochar (BCA) in mitigating the toxic effects of copper in Brazilian mahogany plants, analyzing biometrics and gas exchange. The experimental design was in randomized blocks, with five blocks, in a 4 × 3 factorial scheme, corresponding to the control (without Cu) and three concentration of Cu (200, 400, and 600 mg Cu kg) and three levels of BCA (0%, 5% and 10%) proportional to the amount of soil in the pots, totaling sixty experimental units.
