[Assessment of Risk of Development of Diabetes Mellitus Among Physicians of Therapeutic Profile: Results of a Screening Study].

Aim: to assess risk of development of diabetes mellitus (DM) and detection of other metabolic derangements among physicians-internists.

Material And Methods: In an open clinical screening study participated 117 male and 167 female physicians mostly cardiologists and internists from various regions of Russia. All participants filled in standard questionnaires and were subjected to examination which included measurement of height, body mass, waist circumference, determination of adipose tissue mass adiposity analyzer, registration of arterial pressure, and assessment of DM risk using Finnish Diabetes Risk Score (FINDRISC).

Duality in left-right symmetric seesaw mechanism.

We consider type I + II seesaw mechanism, where the exchanges of both right-handed neutrinos and isotriplet Higgs bosons contribute to the neutrino mass. Working in the left-right symmetric framework and assuming the mass matrix of light neutrinos m(v) and the Dirac-type Yukawa couplings to be known, we find the triplet Yukawa coupling matrix f, which carries the information about the masses and mixing of the right-handed neutrinos. We show that in this case there exists a duality: for any solution f, there is a dual solution [symbol: see text] = m(v)/nu(L) - f, where nu(L) is the vacuum expectation value of the triplet Higgs boson.

Describing oscillations of high energy neutrinos in matter precisely.

We present a formalism for precise description of oscillation phenomena in matter at high energies or high densities, V > Delta m(2)/2E, where V is the matter-induced potential of neutrinos. The accuracy of the approximation is determined by the quantity, where is the mixing angle in matter and is a typical change of the potential over the oscillation length (). We derive simple and physically transparent formulas for the oscillation probabilities, which are valid for arbitrary matter density profiles.
