[Ways to improve diagnosis and surgical treatment for pathology of brachiocephalic arteries].

Unlabelled: Over 2010-2013 we anonymously interrogated a total of 397 therapeutists of municipal polyclinics of six regions of Russia (Chelyabinsk, Kurgan, Sverdlovsk, Orenburg, and Saratov Regions and the Republic of Bashkortostan), studying their awareness of the indications and

Aim: of ultrasound examination of brachiocephalic arteries (US BCA) in patients presenting with arterial hypertension (AH) and revealing the physicians' attitude to carrying out surgical prevention of stroke in hypertensive patients. As the indications for USS BCA 35 (8.82%) of physicians reported symptoms of local cerebrovascular lesions, mentioning: "complaints of unilateral weakness in the extremities" (n=18), "complaints of speech impairments disorders" (n=2), "complaints of loss of fields of vision" (n=4), "endured TIA" (n=11).

Optimization of the target of an accelerator-driven neutron source through Monte Carlo numerical simulation of neutron and gamma transport by the PRIZMA code.

At Budker Institute of Nuclear Physics, epithermal neutron source for neutron-capture therapy was built and neutron generation was realized. Source is based on tandem accelerator and uses near-threshold neutron generation from the reaction (7)Li(p,n)(7)Be. The paper describes target optimization through the numerical simulation of proton, neutron and gamma transport by Monte Carlo method (PRIZMA code).
