Training-induced changes in architecture of human skeletal muscles: Current evidence and unresolved issues

Journal of Physical Fitness and Sports Medicine, 2016
The present review summarizes current evidence and unresolved issues regarding training-induced changes in the architecture of human skeletal muscles. As architectural parameters, we focused on the fascicle length and pennation angle, which are related ...

Comparison of Capillary Architecture between Slow and Fast Muscles in Rats Using a Confocal Laser Scanning Microscope [PDF]

, 2010
The skeletal muscle is classified into 2 types, slow oxidative or fast glycolytic muscle. For further characterization, we investigated the capillary architecture in slow and fast muscles.

The Importance of Lean Body Mass for the Rate of Force Development in Taekwondo Athletes and Track and Field Throwers

Journal of Functional Morphology and Kinesiology, 2018
The rate of force development (RFD) is vital for power athletes. Lean body mass (LBM) is considered to be an essential contributor to RFD, nevertheless high RFD may be achieved by athletes with either high or low LBM. The aim of the study was to describe

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Are mice good models for human neuromuscular disease? Comparing muscle excursions in walking between mice and humans [PDF]

, 2017
The mouse is one of the most widely used animal models to study neuromuscular diseases and test new therapeutic strategies. However, findings from successful pre-clinical studies using mouse models frequently fail to translate to humans due to various ...
