Reference curves of the body fat index in adolescents and their association with anthropometric variables

Jornal de Pediatria (Versão em Português), 2015
Objectives: To develop reference curves for the body fat index (BFI) in the pediatric population, in adolescents from the city of São Paulo, Brazil, and verify their association with body mass index and body fat percentage.

Analyses of body composition charts among younger and older Chinese children and adolescents aged 5 to 18 years

BMC Public Health, 2012
Background Childhood obesity has become a major public health problem in China. The objective of this study was to examine the effect of age and sex on the relationship between fat-free mass (FFM) and fat mass (FM), fat-free mass index (FFMI) and fat ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

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

Associations of Body Mass and Fat Indexes With Cardiometabolic Traits

Journal of the American College of Cardiology, 2018
Body mass index (BMI) is criticized for not distinguishing fat from lean mass and ignoring fat distribution, leaving its ability to detect health effects unclear.The aim of this study was to compare BMI with total and regional fat indexes from dual-energy x-ray absorptiometry in their associations with cardiometabolic traits.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

High impact activity is related to lean but not to fat mass: findings from a population-based study in adolescents [PDF]

, 2012
Background: Objective measures of physical activity calibrated against energy expenditure may have limited utility in studying relationships with musculoskeletal phenotypes.

Analysis of body composition parameters: Associations with gender, age, and adiposity indices in adults

Asian Journal of Medical Sciences
Background: Height-independent body composition parameters such as fat free mass index (FFMI) and body fat mass index (BFMI) allow height-independent interpretation of nutrition status and putatively provide a better assessment of body fat.

Assessing body composition by bioelectric impedance analysis and dual-energy X-ray absorptiometry in physically active normal and overweight Indian males

National Journal of Physiology, Pharmacy and Pharmacology, 2018
Background: To improve body composition measurement methods for physically active healthy individuals, validation with of bioelectric impedance analysis (BIA) with using dual-energy X-ray absorptiometry (DXA) on basis of variation in body mass index (BMI)

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...
