The Role of Genetics and Epigenetic Regulation in the Pathogenesis of Osteoarthritis.

Osteoarthritis (OA) is progressive disease characterised by cartilage degradation, subchondral bone remodelling and inflammation of the synovium. The disease is associated with obesity, mechanical load and age. However, multiple pro-inflammatory immune mediators regulate the expression of metalloproteinases, which take part in cartilage degradation.

Association Study of and Genetic Variants in Gallstone Disease.

There is growing evidence that gallstone formation may be genetically determined. Recent studies have shown that polymorphism of genes encoding proteins involved in bile acid transport may be associated with the risk of gallstone disease. The aim of this study was to investigate the association between SLCO1B3 (rs4149117:G>T, rs7311358:A>G) and ABCC3 (rs4793665:T>C, rs11568591:G>A) genetic variants and susceptibility to cholesterol gallstone disease, as well as gallstone composition.

VAV1 Gene Polymorphism is Associated With Kidney Allograft Rejection.

Background: VAV1 is an intracellular signal transduction protein that plays a significant role in signal transduction in T cells. Several studies suggest that VAV1 signaling plays significant roles in allograft rejection. The aim of this study was to examine the association between VAV1 gene polymorphisms and renal allograft function.

TNF-α and IL10 gene polymorphisms in women with postmenopausal osteoporosis.

Objective: Postmenopausal osteoporosis is a common disorder characterized by decreased bone mineral density (BMD). Proinflammatory cytokines are among the significant factors involved in bone turnover. They are the stimulants of bone resorption, acting directly on osteoclasts and osteoclast precursors.

[Pregnancy in a rudimentary horn of the uterus].

Pregnancy in a rudimentary horn of the uterus, a rare form of ectopic pregnancy, develops in women affected by developmental abnormalities of the growth and fusion of the Müllerian paramesonephric ducts. In the Polish population, this problem affects 4-8 women per year. The paper analyzes the problems that are associated with pregnancy developing in the rudimentary horn.

Causes of respiratory ailments in pregnancy.

Objective: During pregnancy, especially during its third trimester, most pregnant women reported respiratory discomfort (dyspnea), despite the absence of previously coexisting respiratory illnesses. The aim of this study was to determine the reason for this discomfort.

Material And Methods: The study included 24 women examined before and after childbirth.

Ionic support of the cough reflex.

Introduction: The aim of this study was to determine the role ofintra-wall nervous and neurohormonal system in the control of airway transport of sodium and chloride ions, as well as to identify regulating mechanisms having an effect on the permanent electric potential of airway tissue, named the transepithelial electric potential (PD) and on reversible changes of this potential (dPD). Using amiloride, a sodium ion blocker, and bumetanide, a blocker of the chloride ion co-transport system, the importance oftransepithelial sodium and chloride ion transport for support of the cough reflex was determined. The conditions were identified for examination of chloride secretion in the airways presented as the chemical isolation of chloride currents with the use of amiloride.

[Evaluation of respiratory tract function in healthy women in the last month of uncomplicated pregnancy].

Unlabelled: The aim of this work was to examine the function of the respiratory system in pregnant women in the last month of non-complicated pregnancy. Spirometry with Lungtest 1000 was performed in 31 pregnant women at a mean gestational age of 37.72 weeks.
