Kindler syndrome is characterized by acral blister formation in infancy and childhood, poikiloderma and cutaneous atrophy. Undoubtedly, similarities of the clinical features exist between Kindler syndrome and Epidermolysis bullosa simplex with mottled pigmentation. In this article, we report 3 patients with Kindler syndrome. Until the Bullous component of Kindler syndrome is more completely und...
The number of spanning clusters in four to nine dimensions does not fully follow the expected size dependence for random percolation. Researchers were interested already long ago in percolation theory above the upper critical dimension of six [1, 2], and we followed [3]. At the perco-lation threshold [4], there is a theoretical consensus that the number N of spanning clusters stays finite with ...
Nephrogenic ascites is a condition characterized by the presence of massive ascites in a patient with ESRD. Neither the exact cause nor the pathogenesis of ascites formation is clearly understood. Patients frequently present with hypertension, moderate to massive ascites, minimal extremity edema, cachexia, and a history of dialysis-associated hypotension. The ascitic fluid is typically an exuda...
Muscle contraction results from cyclic interactions between the contractile proteins myosin and actin, driven by the turnover of adenosine triphosphate (ATP). Despite intense studies, several molecular events in the contraction process are poorly understood, including the relationship between force-generation and phosphate-release in the ATP-turnover. Different aspects of the force-generating t...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
