What's killing lab yeast around the world?

Multiple researchers are reporting toxic agar, but the ultimate culprit remains unclear.

Quantification of the median fluorescence intensity of CD3 and CD4 in mycosis fungoides/Sezary syndrome versus non-neoplastic control cases in peripheral blood.

Peripheral blood involvement by MF/SS has significant implications for prognosis and treatment. Flow cytometry is commonly used to assess MF/SS by analyzing the ratio of CD26- and/or CD7-CD4 + T cells and assessment of immunophenotypic abnormalities. However, distinguishing normal from abnormal cells is not always easy.

It's about time to exercise: development of the Exercise Participation Explained in Relation to Time (EXPERT) model.

A perceived 'lack of time' is consistently the most commonly reported barrier to exercise. However, the term fails to capture the multifaceted nature of time-related factors. Recognising the need for a more comprehensive analysis of 'lack of time' as a barrier to exercise, the aim of this study was to develop the exercise participation explained in relation to time (EXPERT) model.

Exposing kinetic disparities between inflammasome readouts using time-resolved analysis.

The NLRP3 inflammasome is an intracellular multiprotein complex described to be involved in both an effective host response to infectious agents and various diseases. Investigation into the NLRP3 inflammasome has been extensive in the past two decades, and often revolves around the analysis of a few specific readouts, including ASC-speck formation, caspase-1 cleavage or activation, and cleavage and release of IL-1β and/or IL-18. Quantification of these readouts is commonly undertaken as an endpoint analysis, where the presence of each positive outcome is assessed independently of the others.

Feasibility and preliminary efficacy of a theory-informed resistance exercise training single-arm intervention for major depression.

Unlabelled: Many adults with major depressive disorder (MDD) do not receive effective treatment. The potential benefits of resistance exercise training (RET) are understudied and may be mechanistically related to cerebral blood flow changes.

Purpose: To assess feasibility, acceptability, and preliminary efficacy of a 16-week, theory-informed RET trial for the treatment of MDD and explore changes in cerebral blood flow.

Resistance exercise for anxiety and depression: efficacy and plausible mechanisms.

Anxiety and depressive symptoms and disorders are prevalent and poorly treated. The salutary benefits of resistance exercise training (RET), a potential alternative therapy, are well established, but mental health effects are understudied. This forum article summarizes the most rigorous evidence regarding efficacy of resistance exercise and provides a primer for putative psychobiological mechanisms.

Do changes in mood and anxiety mediate exercise-induced reductions in alcohol cravings? An exploratory study.

Objective: Exercise is increasingly used as adjunct treatment for alcohol use disorder (AUD). Evidence suggests that moderate-to-high-intensity exercise can ameliorate cravings. We explored the potential mediating effects of changes in mood states in the relationship between exercise intensity and alcohol cravings.

Physical activity dose for generalized anxiety disorder & worry: Results from the Irish longitudinal study on ageing.

The lowest moderate-to-vigorous physical activity (MVPA) dose that conveys protection for Generalized Anxiety Disorder (GAD) and worry is unknown. This study quantified associations of weekly accumulated MVPA doses with GAD and worry across 10 years using data from The Irish Longitudinal Study on Ageing (TILDA). Continuous MVPA (metabolic equivalent of task [MET] minutes per week [MET.

Real-world outcomes of children treated with dupilumab for moderate-to-severe atopic dermatitis: a single-centre retrospective observational UK study.

Background: Dupilumab is licensed for the treatment of moderate-to-severe atopic dermatitis (AD) in patients aged ≥ 6 months.

Objectives: The aim of this study was to examine real-world outcomes and safety of dupilumab in British children with moderate-to-severe AD attending a tertiary referral paediatric centre.

Methods: Skin and quality of life scores, adverse events and discontinuation rates were assessed.

Global Alliance for the Promotion of Physical Activity: the Hamburg Declaration.

Non-communicable diseases (NCDs), including coronary heart disease, stroke, hypertension, type 2 diabetes, dementia, depression and cancers, are on the rise worldwide and are often associated with a lack of physical activity (PA). Globally, the levels of PA among individuals are below WHO recommendations. A lack of PA can increase morbidity and mortality, worsen the quality of life and increase the economic burden on individuals and society.

Effects of resistance exercise training on depressive symptoms among young adults: A randomized controlled trial.

Evidence supports the antidepressant effects of resistance exercise training (RET); however, findings among young adults at-risk for elevated depressive symptoms are limited. This randomized controlled trial examined the effects of eight weeks of ecologically-valid, guidelines-based RET, compared to a wait-list control, on depressive symptoms among 55 young adults (26±5y; 36 female) with and without subclinical, or analogue, Generalized Anxiety Disorder (AGAD; Psychiatric Diagnostic Screening Questionnaire GAD subscale ≥6 and Penn State Worry Questionnaire ≥45) and Major Depressive Disorder (AMDD). Following a three-week familiarization period, participants completed one-on-one, twice-weekly RET sessions.

Physical Activity Dose and Depression in a Cohort of Older Adults in The Irish Longitudinal Study on Ageing.

Importance: Among older adults (aged ≥50 years), depression is associated with an increased risk of physical, social, and cognitive dysfunction. Regular moderate to vigorous physical activity (MVPA) has been associated with lower odds of depression. However, the lowest dose for protection against depression and the extent to which exceeding this level conveys additional protection are unknown.

Physical activity for depression among the chronically Ill: Results from older diabetics in the Irish longitudinal study on ageing.

Among chronically-ill older adults, the benefits of moderate-to-vigorous physical activity (MVPA) are established. Comorbid depressive symptoms and Major Depression are prevalent among the chronically-ill, but how different doses of MVPA may protect against depression remains understudied. Thus, using 10 years of data from The Irish Longitudinal Study on Ageing, we quantified longitudinal associations between MVPA doses and depressive symptoms and Major Depression among chronically-ill older adults living with type 2 diabetes (T2DM).

Dose-response effects of acute exercise intensity on state anxiety among women with depression.

Anxiety is common in people with major depressive disorder (MDD), yet the anxiolytic effects of acute exercise in MDD are unknown. The purpose of this analysis was to determine a potentially optimal acute exercise intensity for reducing state anxiety in women with MDD, the duration of the response, and the potential influences of depression severity and preferred-intensity exercise. Using a within-subject, randomized, counter-balanced design, 24 participants completed five separate visits including 20  min of steady-state bicycling at prescribed ( RPE) light, moderate, or hard intensities, a preferred/self-selected session, or a quiet rest (QR) session.

Dual-pharmacophore artezomibs hijack the Plasmodium ubiquitin-proteasome system to kill malaria parasites while overcoming drug resistance.

Artemisinins (ART) are critical anti-malarials and despite their use in combination therapy, ART-resistant Plasmodium falciparum is spreading globally. To counter ART resistance, we designed artezomibs (ATZs), molecules that link an ART with a proteasome inhibitor (PI) via a non-labile amide bond and hijack parasite's own ubiquitin-proteasome system to create novel anti-malarials in situ. Upon activation of the ART moiety, ATZs covalently attach to and damage multiple parasite proteins, marking them for proteasomal degradation.

Sticking with it? Factors associated with exercise adherence in people with alcohol use disorder.

Background: Emerging evidence suggests that exercise may be an efficacious treatment for alcohol use disorder (AUD), but adherence is suboptimal. We examined factors associated with adherence to an exercise intervention for non-treatment seeking adults with AUD.

Methods: This secondary analysis of a randomized controlled trial included 95 physically inactive adults aged 18-75 years with clinician-diagnosed AUD.

Effects of exercise on cognitive functioning in adults with serious mental illness: A meta analytic review.

Cognitive performance is usually impaired in those with serious mental illness (SMI). Exercise may improve cognitive functioning, but studies examining the effects of exercise in SMI indicate heterogenous findings. To estimate the effects of exercise on cognitive outcomes in people with SMI.

Risk Factors for Reinfection with SARS-CoV-2 Omicron Variant among Previously Infected Frontline Workers.

In a cohort of essential workers in the United States previously infected with SARS-CoV-2, risk factors for reinfection included being unvaccinated, infrequent mask use, time since first infection, and being non-Hispanic Black. Protecting workers from reinfection requires a multipronged approach including up-to-date vaccination, mask use as recommended, and reduction in underlying health disparities.
