Pentaquark baryons in SU(3) quark model
We study the SU(3) group structure of pentaquark baryons which are made of
four quarks and one antiquark. The pentaquark baryons form {1}, {8}, {10},
{10}-bar, {27}, and {35} multiplets in SU(3) quark model. First, the flavor
wave functions of all the pentaquark baryons are constructed in SU(3) quark
model and then the flavor SU(3) symmetry relations for the interactions of the
pentaquarks with three-quark baryons and pentaquark baryons are obtained.Comment: REVTeX, 36 pages, 8 figures, references added, section for mass sum

Economic benefit of using testosterone gel (used externally) in men with diabetes mellitus and testosterone deficiency
BACKGROUND: High prevalence of type 2 diabetes mellitus (T2DM) and its input to the increase of mortality indicate that social and economic value of this disease and financial burden are great. Testosterone replacement therapy (TRT) enhances the effectiveness of T2DM treatment. A research was conducted to assess if Androgel® therapy in diabetic men is cost-effective. OBJECTIVES: Defining of economic benefit of adding “Androgel” to the T2DM treatment in men with testosterone deficiency. MATERIALS AND METHODS: Economic modeling and results of other clinical studies were used in the analysis. A guildeline of The Scottish Intercollegiate Guidelines Network (SIGN) was used for clinical study selection, development of economic modelling and study design, assessment of study quality. The study analyzed clinical effects (fasting morning glycemia, glycosylated hemoglobin, HOMA index) and mortality reduce. RESULTS: It was shown that TRT can help to reduce costs of glycemic control, to increase efficiency in terms of cost-effectiveness analysis. Target HbA1c value can be reached by additional cost of 569.39 roubles for every patient. There is a possible additional income from 454.100 to 8.896.186 rubles though reduced mortality. CONCLUSION: Thus, testosterone replacement therapy was shown as cost effective due to reduced costs. The analysis demonstrated HbA1c target achievement and, as a result, reduction of the T2DM outcomes and reduced mortality. There is a possible additional income from 454.100 to 8.896.186 rubles per year
Broadband X-ray spectrum of XTE J1550-564 during 2003 outburst
Results of broadband INTEGRAL and RXTE observations of the Galactic
microquasar XTE J1550-564 during outburst in spring 2003 are presented. During
the outburst the source was found in a canonical low/hard spectral state.Comment: 5 pages, 3 figures. Accepted for publication in Astronomy Letter
