The incidence of fractures is substantially increased in patients with chronic kidney disease (CKD) compared to the general population. The factors associated with increased bone fracture in this population are not well understood. Vitamin D deficiency has been associated with decreased bone mass and higher incidence of fractures in the general population.(More)
Adherent and tight junction molecules have been described to contribute to carcinogenesis and tumor progression. Additionally, the group of claudin-low tumors have recently been identified as a molecular subgroup of breast carcinoma. In our study, we examined the expression pattern of claudins, beta-catenin and E-cadherin in invasive ductal (IDCs) and(More)
A comparative study of the radial distribution of the total phenol contents has been carried out on two Beech (Fagus sylvatica L.) discs, one with red heartwood and the other without red heartwood. The wood disc samples were investigated immediately after felling and at the different stages of room-drying. In the disc without red heartwood the(More)
Subject Though, the site and the vitality of trees have a strong in ̄uence on the pH in wood, the various tree species can be characterized by average pH values. In the heartwood the pH of trees decreases (Sandermann, Rothkamm 1959). The average pH of sap from beech wood is 5.5. The pH values of sapand heartwood were measured to be 5.13 and 5.06(More)
The relationship between parathyroid function, an important determinant of bone turnover, and bone mineral density (BMD) in patients with chronic kidney disease is not fully understood. We wanted to analyze the association between BMD and parathyroid function in hemodialysis patients in details. In a cross-sectional design, data from 270 patients (age 55 ±(More)
The etiology of tumors in young age is not precisely known yet, but studies on the topic generally agree that in this group of patients the traditionally known behavioural risk factors (tobacco and alcohol abuse) play no or a significantly less important role. Oral squamous cell carcinoma occurring at a young age is a topic of utmost importance that is(More)
Primary and metastatic malignant tumors appears frequently in the head and neck region. The occurrence of malignancies in tissues--transplanted to this area--are extraordinary rare. Authors report about a case, where the tumor developed in a cylindroid jump flap, used to the closure of the cleft palate. They discuss theoretical aspects, as well as the(More)
