Evaluation of the radiation risk of medical examinations in the Russian Federation taking into account the age and sex distribution of the patients

Радиационная гигиена, 2022
The aim of the study was to develop a methodology that allows taking into account the age and sex dependencies of the risk of radiogenic cancer and the age and sex distribution of the patients to evaluate the collective risk due to separate X-ray ...

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

FEBS 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.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Minimal Surviving Inoculum in Collective Antibiotic Resistance

mBio, 2023
A common strategy used by bacteria to resist antibiotics is enzymatic degradation or modification. This reduces the antibiotic threat in the environment and is therefore potentially a collective mechanism that also enhances the survival of nearby cells ...

[Nationwide survey of nuclear medicine practice and estimation of collective effective dose in Japan.].

Igaku butsuri : Nihon Igaku Butsuri Gakkai kikanshi = Japanese journal of medical physics : an official journal of Japan Society of Medical Physics, 2006
For the estimation of collective effective dose from radiopharmaceuticals used in nuclear medicine diagnosis, a national survey was carried out in Japan. The survey contents covered radiopharmaceutical use, sex, age, activity, and so on of each patient in October 1997 and the monthly number of examinations in 1997.

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
