PD-1 Alleviates Cisplatin-Induced Muscle Atrophy by Regulating Inflammation and Oxidative Stress

open access: yesAntioxidants, 2022
Skeletal muscle atrophy is an important characteristic of cachexia, which can be induced by chemotherapy and significantly contributes to functional muscle impairment.

Posterior cortical atrophy

open access: yesThe Lancet Neurology, 2012
Posterior cortical atrophy (PCA) is a neurodegenerative syndrome that is characterised by progressive decline in visuospatial, visuoperceptual, literacy, and praxic skills. The progressive neurodegeneration affecting parietal, occipital, and occipitotemporal cortices that underlies PCA is attributable to Alzheimer's disease in most patients.

Monomelic Atrophy [PDF]

open access: yesCanadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1990
ABSTRACT:Weakness of distal muscles of one upper limb which progresses over 1 year and then appears to arrest (“monomelic amyotrophy”) has been reported mainly in Japan and India. We report 5 cases of a similar syndrome occurring in Canada. In our cases the wasting affected the forearm muscles of one upper limb (sparing brachioradialis and extensor ...

mTOR as a Key Regulator in Maintaining Skeletal Muscle Mass

open access: yesFrontiers in Physiology, 2017
Maintenance of skeletal muscle mass is regulated by the balance between anabolic and catabolic processes. Mammalian target of rapamycin (mTOR) is an evolutionarily conserved serine/threonine kinase, and is known to play vital roles in protein synthesis ...

Altered Ca2+ Handling and Oxidative Stress Underlie Mitochondrial Damage and Skeletal Muscle Dysfunction in Aging and Disease

open access: yesMetabolites, 2021
Skeletal muscle contraction relies on both high-fidelity calcium (Ca2+) signals and robust capacity for adenosine triphosphate (ATP) generation. Ca2+ release units (CRUs) are highly organized junctions between the terminal cisternae of the sarcoplasmic ...

Longitudinal tau accumulation and atrophy in aging and alzheimer disease

open access: yesAnnals of Neurology, 2019
To determine the rate of tau accumulation in healthy older adults (OA) and patients with Alzheimer disease (AD), as well as the relationship of tau accumulation to cortical atrophy.

Glycine Protects Muscle Cells From Wasting in vitro via mTORC1 Signaling

open access: yesFrontiers in Nutrition, 2019
Glycine supplementation can protect skeletal muscles of mice from cancer-induced wasting, but the mechanisms underlying this protection are not well-understood.

Preliminary Observations on Skeletal Muscle Adaptation and Plasticity in Homer 2-/- Mice

open access: yesMetabolites, 2021
Homer represents a diversified family of scaffold and transduction proteins made up of several isoforms. Here, we present preliminary observations on skeletal muscle adaptation and plasticity in a transgenic model of Homer 2-/- mouse using a multifaceted

Denervation drives skeletal muscle atrophy and induces mitochondrial dysfunction, mitophagy and apoptosis via miR-142a-5p/MFN1 axis

open access: yesTheranostics, 2020
Rationale: Peripheral nerve injury is common in clinic, which leads to severe atrophy and dysfunction of the denervated muscles, but the underlying mechanism is not fully understood. Recent studies advanced the causative role of mitochondrial dysfunction

The Inheritance of Peripapillary Atrophy [PDF]

open access: yesInvestigative Opthalmology & Visual Science, 2007
To estimate the relative importance of genes and environment in peripapillary atrophy type beta (beta-PPA) in a classic twin study.Female twin pairs (n = 506) aged 49 to 79 years were recruited from the St. Thomas' UK Adult Twin Registry. Peripapillary atrophy was identified from masked grading of stereoscopic optic disc photographs.
