INTRODUCTION The clinical and histological presentations of the adult form of Pompe disease may be atypical. In such cases, identifying histological signs that point to the diagnosis would be crucial to avoid a delay in care. The aim of our study was to investigate the presence of rimmed vacuoles and acid phosphatase positivity in muscle biopsies of patients with late-onset Pompe disease. MAT...

PURPOSE OF REVIEW Distal myopathy with rimmed vacuoles or hereditary inclusion body myopathy is an adult-onset autosomal recessive, slowly progressive and debilitating myopathy due to mutations in the gene that regulates the synthesis of sialic acid. This review aims to update our knowledge of this myopathy and to review studies about pathomechanism and therapeutic strategies. RECENT FINDINGS...

When repairing or reinforcing existing structures made of old mild steel, the preferred joining method may be welding rather than bolting, as is usually case. Due to specific properties steels, special problems have considered. The weldability steels particularly influenced by their highly scattering chemical composition, inclusions and distribution in component well limited material toughness....

The protein synthesis and degradation of eukaryotic cells must be highly selective and tightly regulated to maintain cellular homeostasis. Like other tissues, muscle contains multiple pathways for protein breakdown including the lysosomal, Ca2+-dependent, and cytosolic ATP-dependent and independent proteolytic systems. These pathways are considered to play important roles not only in cellular d...

Distal myopathy with rimmed vacuoles (DMRV) or hereditary inclusion myopathy (h-IBM) is an early adult-onset distal myopathy caused by mutations in the UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE) gene which encodes for a bifunctional enzyme involved in sialic acid biosynthesis. It is pathologically characterized by the presence of rimmed vacuoles especially in atrophic ...
