Dynamic repositioning of telomeres is a unique feature of meiotic prophase I that is highly conserved among eukaryotes. At least in fission yeast it was shown to be required for proper alignment and recombination of homologous chromosomes. On entry into meiosis telomeres attach to the nuclear envelope and transiently cluster at a limited area to form a(More)
The LEM motif is a sequence of 40-50 amino acids that has been identified in a number of non-related proteins of the inner nuclear membrane including the lamina-associated polypeptides 2 (LAP2), emerin, MAN1 and the Drosophila protein otefin. This evolutionary conserved sequence motif can mediate via the interaction with the small protein BAF the binding of(More)
UNLABELLED Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in industrialized countries and may proceed to steatohepatitis (NASH). Apoptosis and free fatty acid (FFA)-induced lipotoxicity are important features of NASH pathogenesis. We have shown a hepatoprotective effect of adiponectin in steatotic livers of hepatitis C virus (HCV)(More)
BACKGROUND LINC complexes are nuclear envelope bridging protein structures formed by interaction of SUN and KASH proteins. They physically connect the nucleus with the peripheral cytoskeleton and are critically involved in a variety of dynamic processes, such as nuclear anchorage, movement and positioning and meiotic chromosome dynamics. Moreover, they are(More)
Background Neuroendocrine tumors (NET) account for one-third of all small bowel neoplasms. The search for the primary tumor in NET is important, even though it is difficult to localize, as its surgical excision leads to a better prognosis, even in metastasized stages of the disease. The objective of this study was to evaluate the use of double balloon(More)
A retroperitoneal tumor in the region of the adrenal gland was diagnosed in a 56-year-old woman. The patient had been suffering from a dull abdominal pain for nearly four weeks before consulting her family physician. Ultrasound, CT and MRI scans revealed a giant tumor of the right adrenal gland. Endocrine activity could not be demonstrated. The size of the(More)
BACKGROUND Decreased vitamin D levels have been described in various forms of chronic liver disease and associated with advanced fibrosis. Whether this association is a cause or consequence of advanced fibrosis remains unclear to date. AIMS To analyse combined effects of 25-OH vitamin D plasma levels and vitamin D receptor gene (VDR; NR1I1) polymorphisms(More)
BACKGROUND & AIMS In the last decade, pegylated interferon-α (PegIFN-α) plus ribavirin (RBV) was the standard treatment of chronic hepatitis C for genotype 1, and it remains the standard for genotypes 2 and 3. Recent studies reported associations between RBV-induced anemia and genetic polymorphisms of concentrative nucleoside transporters such as CNT3(More)
BACKGROUND A free gingival graft (FGG) is currently the gold standard for augmenting small areas of keratinized mucosa. The porcine collagen matrix (CM) represents an alternative to autologous tissue harvesting. This study aims to compare the CM versus FGGs for augmenting keratinized peri-implant mucosa based on clinical and histologic evaluations. (More)
