The extent and nature of southeastern Europe (SEE) paternal genetic contribution to the European genetic landscape were explored based on a high-resolution Y chromosome analysis involving 681 males from seven populations in the region. Paternal lineages present in SEE were compared with previously published data from 81 western Eurasian populations and 5,017 Y chromosome samples. The finding that five major haplogroups (E3b1, I1b* (xM26), J2, R1a, and R1b) comprise more than 70% of SEE total genetic variation is consistent with the typical European Y chromosome gene pool. However, distribution of major Y chromosomal lineages and estimated expansion signals clarify the specific role of this region in structuring of European, and particularly Slavic, paternal genetic heritage. Contemporary Slavic paternal gene pool, mostly characterized by the predominance of R1a and I1b* (xM26) and scarcity of E3b1 lineages, is a result of two major prehistoric gene flows with opposite directions: the post-Last Glacial Maximum R1a expansion from east to west, the Younger Dryas-Holocene I1b* (xM26) diffusion out of SEE in addition to subsequent R1a and I1b* (xM26) putative gene flows between eastern Europe and SEE, and a rather weak extent of E3b1 diffusion toward regions nowadays occupied by Slavic-speaking populations.

Veterans with war-related PTSD more often reported developmental problems in their children. Father's PTSD may have long-term and long-lasting consequences on the child's personality.

Acupuncture and clonazepam are similarly effective for patients with BMS.

Changes in immune and inflammatory responses may play a crucial role in the development and progression of atherosclerosis, as an autoimmune, chronic and progressive inflammatory disease. Immunological activity and vascular inflammation during atherosclerosis can be modulated by autoimmune responses against self-antigens, according to changeable risk factors (cholesterol, oxidized low-density lipoprotein (ox-LDL) in the vascular wall, fatty acids, etc.), and accompanied by accumulation of leucocytes and proinflammatory cytokines, which stimulate the transcription of matrix metalloproteinases (MMPs), whose concentration are increased in foam cell-rich regions. Regulatory T cells (Tregs) represent a unique subpopulation of T cells specialized in the regulation of immune response and in the suppression of proatherogenic T cells. The aim of our study was to examine the interactions between the concentration of enzyme matrix metalloproteinases 2 and 9 (MMP-2 and 9) in urine and the percentage of Tregs in peripheral blood of two groups of patients: with carotid artery stenosis (CAS), undergoing surgery and with mild atherosclerosis (A) from general practice. The method of enzyme immunoassay (ELISA) was used to determine enzyme MMP expression, and Tregs was examined by flow cytometric analysis. Our data have showed a large increase in the enzyme MMP-2 and 9 in the urine of CAS and A patients in comparison with healthy controls and indicated this method as an easy marker for the monitoring of the development of atherosclerosis. Simultaneously, the diminished number of Tregs in the same patients pointed the importance of these regulatory mechanisms in the etiopathogenesis of atherosclerosis and possible Tregs-mediated therapy.

We aimed to determine whether the distal end of the humerus had the capacity of spontaneous realignment of the remaining deformity following an inadequate reposition of the supracondylar fracture. The results in 56 children with a supracondylar humerus fracture were analysed. In 45 patients (80%), manual repositioning was performed along with transcutaneous fixation, whereas in 11 patients (20%), only manual repositioning and immobilization in plaster cast was applied. Immobilization was removed and physical therapy was started in all patients on the 21st day following the intervention. Anteroposterior and left-lateral radiography was performed and Baumann's angle was determined. Follow-up radiograph of the elbow of the traumatized and healthy extremity was performed at an interval of 5-15 years (median 9.4). There was no statistically significant difference between the relationship of Baumann's angle of the injured arm measured on the 21st day after the reduction of fragments on the one hand and the carrying angle of the injured and healthy arm measured at the long-term follow-up on the other (t=0.48, P=0.63). Similarly, there was no statistically significant difference between the relationship of Baumann's angle of the injured arm measured at the long-term follow-up and the findings of the carrying angle of both the injured and the healthy arm obtained on the same examination (t=0.78, P=0.44). On the basis of our experience, we conclude that there is no biological capacity to rectify a possible remaining postreduction varus deformity by spontaneous remodelling.
