Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Function of mTOR complex 1 and 2 in skeletal muscle [PDF]
, 2009 Growth of an organ during development and during adaptation in the adult can be controlled by alterations either in the number or the size of cells. The two mechanisms are fundamentally different and require distinct regulation.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Antagonistic control of muscle cell size by AMPK and mTORC1. [PDF]
, 2011 7 pages (2640-2646)International audienceNutrition and physical activity have profound effects on skeletal muscle metabolism and growth. Regulation of muscle mass depends on a thin balance between growth-promoting and growth-suppressing factors. Over the

Reliability of Longus Colli Muscle Size Measurement Using Ultrasonography
Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2009 BACKGROUND AND OBJECTIVE: The deep cervical flexor muscles have a major role to play in neck stabilization and evidence suggests that these muscles especially longus colli muscle (LCM) becomes dysfunctional in the presence of neck pain.

ObesitiesWe examined the effects of combining resistance training (RT) with semaglutide use on body composition, metabolism, strength, and muscle thickness and quality. Men and women (n = 11) aged 30–55 years participated in this study.

Electrically and hybrid-induced muscle activations: effects of muscle size and fiber type
European Journal of Translational Myology, 2016 The effect of three electrical stimulation (ES) frequencies (10, 35, and 50 Hz) on two muscle groups with different proportions of fast and slow twitch fibers (abductor pollicis brevis (APB) and vastus lateralis (VL)) was explored. We evaluated the acute

Muscle hypertrophy and muscle strength: dependent or independent variables? A provocative review
European Journal of Translational Myology, 2020 The question whether the muscle hypertrophy induced by resistance training, hormone administration or genetic manipulation is accompanied by a proportional increase in muscle strength is still open.
