Spontaneous physical activity down-regulates Pax7 in cancer cachexia [PDF]

open access: yes, 2015
Emerging evidence suggests that the muscle microenvironment plays a prominent role in cancer cachexia. We recently showed that NF-kB - induced Pax7 overexpression impairs the myogenic potential of muscle precursors in cachectic mice, suggesting that ...

Interactive Modelling of Volumetric Musculoskeletal Anatomy [PDF]

open access: yesACM Trans. Graph., Vol. 40, No. 4, Article 122. Publication date: August 2021, 2021
We present a new approach for modelling musculoskeletal anatomy. Unlike previous methods, we do not model individual muscle shapes as geometric primitives (polygonal meshes, NURBS etc.). Instead, we adopt a volumetric segmentation approach where every point in our volume is assigned to a muscle, fat, or bone tissue.

Using a Conformal Water Bolus to Adjust Heating Patterns of Microwave Waveguide Applicators [PDF]

open access: yes, 2017
Background: Hyperthermia, i.e., raising tissue temperature to 40-45°C for 60 min, has been demonstrated to increase the effectiveness of radiation and chemotherapy for cancer.

Skeletal Muscle Fiber Size and Capillarity

open access: yesExperimental Biology and Medicine, 1978
SummaryThe ATPase technique following preincubation in an acid medium (pH 3.8–4.0) was used to visualize capillaries. After preincubation at a pH of 4.5, in combination with the DPNH tetrazolium reductase, it was used to identify fiber types. A positive correlation has been demonstrated between fiber cross sectional area and C:F, indicating that large ...

Skeletal muscle contributions to reduced fitness in cystic fibrosis youth

open access: yesFrontiers in Pediatrics, 2023
BackgroundIncreased maximal oxygen uptake (V̇O2max) is beneficial in children with cystic fibrosis (CF) but remains lower compared to healthy peers.

Muscle contraction and the elasticity-mediated crosstalk effect [PDF]

open access: yesPhys. Rev. E 87, 052714 (2013), 2013
Cooperative action of molecular motors is essential for many cellular processes. One possible regulator of motor coordination is the elasticity-mediated crosstalk (EMC) coupling between myosin II motors whose origin is the tensile stress that they collectively generate in actin filaments.

The effects of hibernation on the contractile and biochemical properties of skeletal muscles in the thirteen-lined ground squirrel, Ictidomys tridecemlineatus [PDF]

open access: yes, 2013
Hibernation is a crucial strategy of winter survival used by many mammals. During hibernation, thirteen-lined ground squirrels, Ictidomys tridecemlineatus, cycle through a series of torpor bouts, each lasting more than a week, during which the animals ...

Effects of Different Combinations of Concentric and Eccentric Resistance Training Programs on Traditional and Alternative Hamstrings-to-Quadriceps Ratios

open access: yesSports, 2019
Resistance training is often recommended for combined increases in traditional and alternative hamstrings-to-quadriceps (H:Q) ratios in order to reduce knee strength imbalance and associated hamstrings and knee ligament injury risk. The aim of this study

Single cell analysis reveals the involvement of the long non-coding RNA Pvt1 in the modulation of muscle atrophy and mitochondrial network [PDF]

open access: yes, 2019
Long non-coding RNAs (lncRNAs) are emerging as important players in the regulation of several aspects of cellular biology. For a better comprehension of their function, it is fundamental to determine their tissue or cell specificity and to identify their

Forearm Flexor Muscles in Children with Cerebral Palsy Are Weak, Thin and Stiff

open access: yesFrontiers in Computational Neuroscience, 2017
Children with cerebral palsy (CP) often develop reduced passive range of motion with age. The determining factor underlying this process is believed to be progressive development of contracture in skeletal muscle that likely changes the biomechanics of ...
