Feasibility of IR-MALDESI Mass Spectrometry Imaging of PFAS.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a class of emerging contaminants that have been in use industrially since the 1940s. Their long-term and extensive commercial use has led to their ubiquitous presence in the environment. The ability to measure the bioconcentration and distribution of PFAS in the tissue of aquatic organisms helps elucidate the persistence of PFAS as well as environmental impacts.

Detecting early cognitive deficits in preclinical Alzheimer's disease using a remote digital multi-day learning paradigm.

Remote, digital cognitive testing on an individual's own device provides the opportunity to deploy previously understudied but promising cognitive paradigms in preclinical Alzheimer's disease (AD). The Boston Remote Assessment for NeuroCognitive Health (BRANCH) captures a personalized learning curve for the same information presented over seven consecutive days. Here, we examined BRANCH multi-day learning curves (MDLCs) in 167 cognitively unimpaired older adults (age = 74.

Antimicrobial resistant Enterobacterales of clinical importance in mute swans.

Urban water environments, including canals, harbours and estuaries are susceptible to contamination with antimicrobials and drug-resistant bacteria through domestic and industrial wastewater discharges and storm water overflows. There is potential for wildlife using these waters to acquire and transmit drug-resistant bacteria and antimicrobial resistance genes (ARGs) of clinical importance. This study aimed to assess clinically important drug-resistant bacteria in urban waterfowl, particularly mute swans.

Lisdexamfetamine in the treatment of methamphetamine dependence: A randomised, placebo-controlled trial.

Aims: This study tested the efficacy and safety of a 12-week course of lisdexamfetamine in reducing methamphetamine use, an outcome which is associated with improvements in health and wellbeing, in people dependent on methamphetamine.

Design, Setting And Participants: This study was a randomised double-blind placebo-controlled trial conducted in six specialist outpatient clinics in Adelaide, Melbourne, Newcastle and Sydney, Australia (2018-2021). Participants were164 adults with methamphetamine dependence, reporting at least 14 use days out of the previous 28 days (62% male, 38% female, < 1% other; mean age 39 years).

Draft genome sequences of sp. MMG031 and sp. MMG032 isolated from the dinoflagellate .

Here, we report the draft genome sequences of sp. MMG031 and sp. MMG032, isolated from coral-associated dinoflagellate , assembled and analyzed by undergraduate students participating in a Marine Microbial Genomics (MMG) course.
