Synergistic effects of a sequential recirculation electrochemical system combined with low-cost UV-LEDs on the gram-negative bacteria inactivation.

In this work, an electrochemical system combined with low-cost UV-LEDs was implemented for the inactivation of Escherichia coli and Pseudomonas aeruginosa. The individual elimination of these bacteria was followed by plate counting and flow cytometry, as complementary techniques to establish the cell inactivation and non-viability, respectively. The contribution of the different parts of the disinfection system (anode, cathode, and light) was determined.

Nucleases: From Primitive Immune Defenders to Modern Biotechnology Tools.

The story of nucleases begins on the ancient battlefields of early Earth, where simple bacteria fought to survive against viral invaders. Nucleases are enzymes that degrade nucleic acids, with restriction endonucleases emerging as some of the earliest defenders, cutting foreign DNA to protect their bacteria hosts. However, bacteria sought more than just defence.

Ten years of monitoring pharmaceuticals and pesticides in the aquatic environment nearby a solid-waste treatment plant: Historical data, trends and risk assessment.

The emission of contaminants of emerging concern (CECs) from wastewater treatment plants has been extensively studied; however, less attention has been paid to municipal solid waste treatment plants (MSWTPs), which can also be a potential source for CECs into surface water (SW) and groundwater (GW) ecosystems. In this work, the environmental impact of a MSWTP located in the province of Castelló, Spain, was studied along a period of ten years (from 2012 to 2022). A total of 173 water samples (including SW and GW) collected from the surrounding of this plant were monitored for 93 compounds (pharmaceuticals and pesticides) by using liquid chromatography coupled to tandem mass spectrometry with triple quadrupole.

Disparities in Access to and Utilization of Surgical Care for Patients with Closed Unstable AO/OTA 44B2 Ankle Fractures and Medicaid.

Background: Closed, unstable AO/OTA 44B2 ankle fractures are common injuries with similar distributions by age, sex, and race. The purpose of this study was to identify disparities in access to and utilization of surgical care for these injuries.

Methods: Ambulatory patients ≥18 years of age with capitated Medicaid health insurance who presented from January 2016 to February 2020 with an isolated, closed AO/OTA 44B2 ankle fracture with radiographic evidence of instability were retrospectively identified at 1 Level-I safety-net trauma center.

Objective: To design and evaluate an educational video aimed at promoting HIV testing in gay men from the theoretical perspective of the Nola J. Pender Health Promotion Model.

Methods: The design comprised five steps: 1.
