Effective ways of handling events in Central and Eastern Europe

Five hundred and sixty-one managers in Central and Eastern Europe were asked how much they relied on each of eight sources of quidance in handling eight relatively routine work events. A previous study indicated particularly strong reliance on one's own experience and training in the Czech Republic and Hungary. Managers from Poland and Slovakia relied more on superiors, while in Romania and Bulgar

Gene fusions in soft tissue tumors: Recurrent and overlapping pathogenetic themes.

Gene fusions have been described in approximately one-third of soft tissue tumors (STT); of the 142 different fusions that have been reported, more than half are recurrent in the same histologic subtype. These gene fusions constitute pivotal driver mutations, and detailed studies of their cellular effects have provided important knowledge about pathogenetic mechanisms in STT. Furthermore, most fus

Maladaptive plasticity of serotonin axon terminals in levodopa-induced dyskinesia.

OBJECTIVE:: Striatal serotonin projections have been implicated in levodopa-induced dyskinesia by providing an unregulated source of dopamine release. We set out to determine whether these projections are affected by levodopa treatment in a way that would favor the occurrence of dyskinesia. METHODS:: As an index of terminal serotonin innervation density, we measured radioligand binding to the plas

Oxygen-dependent copper toxicity: targets in the chlorophyll biosynthesis pathway identified in the copper efflux ATPase CopA deficient mutant

Characterization of a copA(-) mutant in the purple photosynthetic bacterium Rubrivivax gelatinosus under low oxygen or anaerobic conditions, as well as in the human pathogen Neisseria gonorrhoeae identified HemN as a copper toxicity target enzyme in the porphyrin synthesis pathway. Heme synthesis is, however, unaffected by copper under high oxygen tension because of the aerobic coproporphyrinogen

Delayed reactions to reusable protective gloves.

The materials in plastic protective gloves are thought to cause less contact allergy than rubber gloves. Our aim was to estimate the frequency of delayed reactions to different types of reusable protective gloves among dermatitis patients. 2 x 2 cm pieces of polyvinyl chloride (PVC) gloves, nitrile gloves, and natural rubber latex (NRL) gloves were tested as is in consecutive dermatitis patients t

Discordant HER2 overexpression in primary and metastatic upper gastrointestinal adenocarcinoma signifies poor prognosis.

Targeted therapy with trastuzumab has proven to be effective for patients with gastric cancer overexpressing the human epidermal growth factor receptor 2 (HER2). Further studies are needed to determine the best method for assessment of HER2 overexpression. Moreover, the prognostic value of HER2 overexpression, including the significance of tumour heterogeneity, remains unclear.

Hand Joint Space Narrowing and Osteophytes Are Associated with Magnetic Resonance Imaging-defined Knee Cartilage Thickness and Radiographic Knee Osteoarthritis: Data from the Osteoarthritis Initiative.

OBJECTIVE: To evaluate whether features of radiographic hand osteoarthritis (OA) are associated with quantitative magnetic resonance imaging (MRI)-defined knee cartilage thickness, radiographic knee OA, and 1-year structural progression. METHODS: A total of 765 participants in Osteoarthritis Initiative (OAI; 455 women, mean age 62.5 yrs, SD 9.4) obtained hand radiographs (at baseline), knee radi

Frequent rearrangements of chromosomes 1, 7, and 8 in primary liver cancer

Fifteen primary liver carcinomas (PLCs), including 12 hepatocellular carcinomas and three cholangiocellular carcinomas, were investigated cytogenetically after short-term culture. Ten tumors displayed clonal chromosomal abnormalities, whereas only normal karyotypes were detected in four cases, and one sample failed to grow in vitro. Structural rearrangements most often involved chromosomes 1, 7, a

Determinants of increasing pulse pressure during 23 years' follow-up as a marker of arterial stiffness and vascular ageing.

The aim was to investigate clinical characteristics of increased brachial pulse pressure (PP) during long-term follow-up (23 years) as a marker of arterial stiffness in 9704 healthy subjects. The association of baseline variables with an increasing PP burden during the study period was analysed by univariate analysis. In addition, the association between different biological variables at baseline

Experimental poststreptococcal glomerulonephritis elicited by IgG Fc-binding M family proteins and blocked by IgG Fc fragment.

Burova L, Pigarevsky P, Seliverstova V, Gupalova T, Schalén C, Totolian A. Experimental poststreptococcal glomerulonephritis elicited by IgG Fc-binding M family proteins and blocked by IgG Fc fragment. APMIS 2012; 120: 221-30. The pathogenesis of acute poststreptococcal glomerulonephritis (APSGN), a major nonsuppurative complication of group A streptococcal (GAS) throat or skin disease, remains un

Regulation of kinin B(2) receptors by bradykinin in human lung cells.

Abstract Bradykinin is a potent mediator of inflammation that has been shown to participate in allergic airway inflammation. The biologic effects of bradykinin are mediated by binding and activating its cognate receptor, the B(2) receptor (B(2)R). In the lung fibroblast cell line IMR-90, binding of bradykinin to the B(2)R triggers down-regulation of the receptor surface expression, suggesting that

Priming for L-DOPA-induced abnormal involuntary movements increases the severity of amphetamine-induced dyskinesia in grafted rats.

In some patients, graft-induced dyskinesia develops following intrastriatal transplantation of embryonic neural tissue for the treatment of Parkinson's disease. The mechanisms underlying these involuntary movements need to be clarified before this approach to clinical cell therapy can be developed further. We previously found that rats with 6-OHDA lesions, primed with L-DOPA treatment and that hav

Normalized motor function but impaired sensory function after unilateral non-reconstructed ACL injury: patients compared with uninjured controls.

Improvement in motor function after anterior cruciate ligament (ACL) injury is achieved by appropriate rehabilitation. However, it has been questioned whether training after injury can lead to sensory improvement. We hypothesized that motor function can be restored after unilateral non-reconstructed ACL injury, whereas the sensory function cannot, i.e., there would be no difference in functional p
