Prevalence, Molecular Identification, Antimicrobial Resistance, and Disinfectant Susceptibility of Listeria innocua Isolated from Ready-to-Eat Foods Sold in Johannesburg, South Africa

open access: yesJournal of Food Quality and Hazards Control, 2021
Background: Food contamination with Listeria spp. can occur at all stages of the food chain. The aim of this research was to investigate the prevalence, molecular identification, antimicrobial resistance, and disinfectant susceptibility of Listeria ...

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

The influence of gender, media, and internet usage on adolescents' fast food perception and fluid intake

open access: yesJournal of Health, Population and Nutrition, 2023
Background Understanding the factors that influence adolescent’s perception of fast food and their fluid consumption is crucial for designing effective nutrition education programs tailored to this population.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Pattern Of Fast Food Consumption Among Medical Students And Its Association With Obesity

open access: yesJournal of Rawalpindi Medical College, 2019
Background: Fast food consumption has been linked to obesity as it contains high saturated fatty acids, sugar, salt, and calories. We conducted this study to determine the pattern of fast food consumption amongst medical students and to assess the ...

Evaluation of Health Indicators and the Quality of Used Frying Oils in Fast Food Restaurants of Mashhad in 2018

open access: yesJournal of Environmental Health and Sustainable Development, 2020
Introduction: Recently, changes in people's lifestyles and new eating habits have diminished the importance of main dishes and have led to increasing the consumption of fast foods.
