Background: Mesenchymal stem cells (MSCs) are multipotent cells, capable of differentiating into different cell lines.They can sense their surrounding biochemical and biophysical factors, which play major roles in their differentiation toward different phenotypes. Therefore, the exposure of these cells to endothelial growth factor (VEGF) as well as hemodynamic biomechanical forces, which act on...

A highly active and stable electrocatalyst for hydrogen evolution is developed based on the in situ formation of MoS 2 nanoparticles on mesoporous graphene foams (MoS 2 /MGF). Taking advantage of its high specifi c surface area and its interconnected conductive graphene skeleton, MGF provides a favorable microenvironment for the growth of highly dispersed MoS 2 nanoparticles while allowing rapi...

Pre-clinical and clinical studies have suggested that sleep loss is a predisposing factor for neurodegeneration and memory impairments linked with Alzheimer’s disease (AD) and about 45% of AD patients show sleep disturbances. Sleep deprivation (SD) alters immuno-inflammatory, oxidantantioxidant enzymes balance and brain derived neurotrophic factor (BDNF) pathways which play significant role in ...

Abstract In this research, we created and tested the validity of a Marginalized-Group-Focused Diversity Climate Scale (MGF-DCS) following Hinkin’s (1998) best practices. Previously, no measure diversity climate has been validated. Furthermore, addressing challenges concerning basis perceptions, reviewed disparate definitions scales to identify its core components sources, focusing on treatment ...

The human insulin-like growth factor-1 (IGF-1) gene gives rise to multiple, heterogeneous mRNA transcripts through a combination of multiple transcription initiation sites, alternative splicing and different polyadenylation signals. These IGF-1 mRNA transcripts code different isoforms of the precursor peptide of IGF-1 (IGF-1Ea, IGF-1Eb and IGF-1Ec or MGF in human skeletal muscle), which also un...

We applied K-means cluster analysis to test the hypothesis that muscle-specific factors known to modulate protein synthesis and satellite cell activity would be differentially expressed during progressive resistance training (PRT, 16 wk) in 66 human subjects experiencing extreme, modest, and failed myofiber hypertrophy. Muscle mRNA expression of IGF-I isoform Ea (IGF-IEa), mechanogrowth factor ...

Skeletal muscle is affected by many hormones and growth factors, both catabolic and anabolic in nature. Our understanding of the synthesis, release, transport and tissue sensitivities of these hormones has increased greatly in recent years. Despite this knowledge we still do not know the link between hormonal/growth factor release, training and muscle hypertrophy. The hormonal response to high ...
