Carbaryl is a broad-spectrum carbamate fungicide that may pose a threat to ecosystems and human health. To prevent and control the harm caused by excessive application of carbaryl, a full-dimensional divergence effect SERS sensor has been constructed. Biodegradable paper chips were used as sensor substrates.

This study reports on the development of a highly sensitive non-enzymatic electrochemical sensor based on a two-dimensional TiCT/MWCNT-OH nanocomposite for the detection of paraoxon-based pesticide. The synergistic effect between the TiCT nanosheet and the functionalized multi-walled carbon nanotubes enhanced the sensor's conductivity and catalytic activity. The nanocomposite demonstrates superior electrochemical and electroanalytical performance compared to the pristine TiCT and MWCNT-OH in detecting paraoxon-ethyl in fruit samples (green and red grapes), with a linear response range from 0.

There is growing interest in transcriptomic points of departure (tPOD) values from in vitro experiments as an alternative to animal test method. The study objective was to calculate tPODs in rainbow trout gill cells (RTgill-W1 following OECD 249) exposed to pesticides, and to evaluate how these values compare to fish acute and chronic toxicity data. Cells were exposed to one fungicide (chlorothalonil), ten herbicides (atrazine, glyphosate, imazethapyr, metolachlor, diquat, s-metolachlor, AMPA, dicamba, dimethenamid-P, metribuzin), eight insecticides (chlorpyrifos, diazinon, permethrin, carbaryl, clothianidin, imidacloprid, thiamethoxam, chlorantraniliprole), and OECD 249 positive control 3,4-dichloroaniline.

The use of ectoparasiticides is a major concern in the control of parasites. In this study, we examined the trends and patterns of veterinary medicines use comparing between a high-risk epidemiological zone (HRZ) and a low-risk epidemiological zone (LRZ) for ectoparasites over a four-year period (2017-2020) at country level data. The objective of this study was to analyze the patterns of ectoparasiticide use in Uruguayan cattle, using the Anatomical Therapeutic Chemical Classification System for Veterinary Drugs (ATCvet) and dose indicators to consider regional variations in the animal population and production intensity.

Department of Hospital Medicine, Intermountain Medical Center, Murray, Utah, USA.
Survivors of acute respiratory failure (ARF) have complex healthcare needs postdischarge, frequently resulting in unmet needs. This prospective multicenter study explores the association between COVID-19 status and unmet healthcare needs in survivors of ARF following hospital discharge. We analyzed patient characteristics and unmet healthcare needs by COVID-19 status using a multivariable regression model with propensity weights.
