Objectives: Dysregulation of systemic phosphate homeostasis is often associated with impairment of musculoskeletal tissue function. Many factors such as calcium levels and dysegulated endocrine mechanisms are thought to contribute. Inorganic phosphate and FGF23 have been shown to act via similar signaling pathways in several cell types but we are not aware of any detailed investigations into their effect on the differentiation and viability of skeletal muscle cells. W...

Background: Disturbance of systemic phosphate homeostasis is often associated with musculoskeletal dysfunction. Multiple factors related to the underlying condition such as calcium levels and endocrine mechanisms are thought to contribute. Distinct effects of inorganic phosphate itself as well as its main regulator FGF23 by activation of similar pathways have been shown in several cell types. We are not aware of any detailed investigations into their effect on the differentiat...

Vascular calcification is a ubiquitous pathology in the aged and diseased vasculature. Recently we have focused on the earliest events in the calcification process and have shown that calcification is initiated in small membrane-bound bodies, or matrix vesicles, derived from both apoptotic and stressed VSMCs. Under normal conditions, these vesicles are loaded with potent inhibitors of mineralization, including matrix Gla protein (MGP) and fetuin-A, which act to block or contro...

Introduction: Aggressive periodontitis (AgP) is an inflammatory disease causing rapid loss of teeth in young patients.Aim: Determine degree of impact of COL1A1 gene on likelihood of AgP development.Materials and methods: Study included 47 patients with AgP, 40 patients with osteoporosis (OP), and 64 healthy patients (HP). Polymorphic variant c.104-441G>T (COL1A1) was studied. Statistics: Fisher’s...

Introduction: Objective of the study is to assess the frequency of osteoporosis and osteoporotic fractures in rheumatoid arthritis (RA) patients with the onset in the age of 55 and elder.Methods: Seventy women with RA (mean age of 62.6 years, mean RA duration of 4.6 years) were examined with dual X-ray absorptiometry (DXA) in three locations (vertebral body L1–L4, femoral neck, and distal radius) and X-ray of vertebral with assessment by Felsenberg....

Perinatal infections appreciably defines the level’s of the neonatal deseases and death rates. The systemic inflammatory response syndrome at the infections can promote the softening of the bone’s tissue in pregnant women and their fetuses.Objectives: Definition of the connection of the level’s calcium-regulated hormones and bone tissue remodeling marker’s in blood at 32 (II) healthy and 48 (I) pregnant women with perinatal infections...

Cam femoro-acetabular impingement (FAI) surgery restores hip range of motion by trimming the head–neck junction, which weakens the proximal femur. Sheep femurs resemble cam deformity and might be suitable for evaluating the impact of the surgical correction. Accordingly, this study addressed two questions: How does increasing head-neck resection affect ovine femoral strength? Are quantitative computed tomography (QCT)-based FE models able to discriminate the observed chan...

Background: Recurrent abdominal pain is common in children and adolescents. This symptom could be raised by the complex of both functional and organic etiologies.Presenting problem: We put forward a seventeen-years-old adolescent girl with personal history of repeated abdominal pain and urinary tract infections. Her family history was negative.Clinical management: Our patient was admitted to hospital due to recurrent abdominal pain...

Introduction: Calcification of vessels, especially media calcification, in combination with bone demineralization and disturbed bone metabolism is abundant in patients suffering from end stage renal disease (ESRD). In this project, we compare biomarkers of calcification with a focus on microRNAs from ESRD patients listed for renal transplantation (RTX) and healthy controls.Methods: Samples are collected from kidney transplant patients. At the same time t...

Subject: To examine the relationship between calcification of the coronary arteries, coronary atherosclerosis and indicators of bone mineral density (BMD) among males with coronary heart disease (CHD).Materials and methods: Seventy-four males with documented CHD were examined. BMD was assessed by dual energy absorptiometry with T-criterion definition of the proximal femur and lumbar spine, coronarography, multispiral computed tomography with quantificati...
