Sarcopenia is a recently defined medical condition described as age-associated loss of skeletal muscle mass and function. Recently, a transgenic mouse model was described linking dispersal of the neuromuscular junction caused by elevated agrin degradation to the rapid onset of sarcopenia. These mice show a significant elevation of serum levels of a(More)
INTRODUCTION Sarcopenia is considered to be an enormous burden for both the individuals affected and for society at large. A multifactorial aetiology of this geriatric syndrome has been discussed. Amongst other pathomechanisms, the degeneration of the neuromuscular junction (NMJ) may be of major relevance. The intact balance between the pro-synaptic agent(More)
BACKGROUND C-terminal Agrin Fragment (CAF) has been proposed as a novel biomarker for sarcopenia originating from the degeneration of the neuromuscular junctions. In patients with stroke muscle wasting is a common observation that predicts functional outcome. We aimed to evaluate agrin sub-fragment CAF22 as a marker of decreased muscle mass and physical(More)
Background: C-terminal Agrin Fragment (CAF) has been proposed as a potential marker for sarcopenia caused by degen-eration of the neuromuscular junction. In patients with ischemic stroke muscle wasting is a common observation. We aimed to evaluate plasma level of total CAF and the sub-fragment AgrinC110 in relation to parameters for physical performance in(More)
BACKGROUND Oxaloacetate decarboxylase (OAD) is a member of the Na(+) transport decarboxylase enzyme family found exclusively in anaerobic bacteria. OAD of Vibrio cholerae catalyses a key step in citrate fermentation, converting the chemical energy of the decarboxylation reaction into an electrochemical gradient of Na(+) ions across the membrane, which(More)
