Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

open access: yesFEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

The effects of heavy screen viewing on the health of secondary school-aged children in Duhok city

open access: yesAdvanced Medical Journal
Background and objectives: Although there has been a remarkable increase in screen time among children over recent years, the literature includes contradictory reports on its effects of the individuals' health.

Longitudinal analysis of the bidirectional relationship between screen time and sleep: Exploring the role of physical activity

open access: yes
BACKGROUND: Excessive screen time and poor sleep duration have significant implications for children's health and well-being. Understanding the dynamic relationship between screen time and sleep duration, as well as the impact of physical activity in ...

Reduce Screen Time KY

open access: yes, 2022
Children, on average, spend 2,000 hours a year in front of screens. The act of binge-watching television releases dopamine in the same way that drug usage does.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Screen Time and Stress

open access: yes
This is an observational study of whether excessive screen time causes stress in young adults, taking place on Twitter. Participants will be divided into a high screen time group and a low screen time group, then have their posts searched for stress ...

Time to screen: rationale and roadmap for HFpEF screening in individuals with obesity

open access: yesHeart Failure Reviews
Abstract Obesity is a major risk factor for heart failure with preserved ejection fraction (HFpEF) and is associated with a distinct pathophysiological phenotype. Individuals with obesity develop HFpEF on average a decade earlier than individuals without obesity. Despite this, systematic screening for HFpEF in individuals with obesity
