Potato Wart Isolates from Europe and North America Form Distinct Clusters of Genetic Variation.

We have extended previously published sets of simple sequence repeat markers for selected to be polymorphic for the German-standard isolates of pathotypes P1, P2, P6, P8, and P18. These markers also complement the extensive published information on DNA polymorphisms for the mitogenomes of . This extended set of 35 markers representing 73 alleles differentiated 51 isolates from Europe and North America into three large, well-separated clusters and subclusters using dendrogram analysis, principal coordinates analysis (PCoA), and population substructure analysis using STRUCTURE 2.

The role of adipocytokines in the pathogenesis of knee joint osteoarthritis.

Osteoarthritis (OA) is one of the most common causes of musculoskeletal disability in the world. Traditionally, it has been thought that obesity contributes to the development and progression of OA by increased mechanical load of the joint structures. Nevertheless, studies have shown that adipose tissue-derived cytokines (adipocytokines) are a possible link between obesity and OA.

[Possibilities of leg length equalization in total hip replacement].

Leg length discrepancy is a common and not appreciated complication after THR. Unequal leg length may cause earlier implant wear, patient's dissatisfaction, impair patient's function or even some legal consequences for the surgeon. To achieve the final equal leg length after surgery one must comply with some rules: proper patient's examination, informing patient about possible leg length discrepancy, proper length measurement- both clinical and radiological after antero-posterior pelvis x-ray; proper radiological length measurements especially when some hip contractures are observed, appropriate implant selection, proper prosthesis templating.

Surgical treatment of dysplastic and isthmic spondylolisthesis.

Background. Dysplastic spondylolisthesis results from a congenital malformation of the vertebral processes, sometimes accompanied by spina bifida; its progression causes subluxation or dislocation in the intervertebral joints and an anterior repositioning of the entire vertebra. Isthmic spondylolisthesis, on the other hand, most often results from a spinal fissure.

Expression of osteoblast marker genes in rat calvarial osteoblast-like cells, and effects of the endocrine disrupters diphenylolpropane, benzophenone-3, resveratrol and silymarin.

Compelling evidence indicates that some endocrine disrupters (EDs), acting as selective estrogen-receptor modulators, interfere with osteoblast differentiation and function. Hence, we investigated whether four EDs [bisphenol-A (BSP), benzophenone-3 (BP3), resveratrol and silymarin] affect differentiation and growth of rat calvarial osteoblast-like (ROB) cells in primary in vitro culture. ROB cells were cultured for up 30 days in a medium supplemented with fetal calf serum (FCS), and conventional RT-PCR detected the expression of collagen-1alpha and osteonectin mRNAs through the entire culture period.

Estradiol and resveratrol stimulating effect on osteocalcin, but not osteonectin and collagen-1alpha gene expression in primary culture of rat calvarial osteoblast-like cells.

Evidence is available that some endocrine disruptors, acting as selective estrogen receptor modulators (SERMs), interfere with osteoblast differentiation and function. Therefore, we investigated whether 17beta-estradiol, bisphenol-A (BSP), silymarin, genistein, resveratrol, procymidone, linurone and benzophenone-3 (BP3) modulate differentiation of rat calvarial osteoblast-like (ROB) cells in primary in vitro culture. Disruptors were added at day 18 of culture and cells were harvested 48 h later.

[The effect of absent ossific nucleus of the femoral head on results of surgical treatment for developmental dislocation of the hip].

We have studied retrospectively 33 hips in 26 children at an average of 9 years 5 months after simultaneous open reduction and Dega transiliac osteotomy for developmental dislocation of the hip (DDH). All children were younger than 2 years of life at the time of surgery. The hips were divided into two groups: with present and with absent ossific nucleus of the femoral head on preoperative radiographs.
