The Zintl compound Ca5Al2Sb6 is a promising thermoelectric material with exceptionally low lattice thermal conductivity resulting from its complex crystal structure. In common with the Al analogue, Ca5In2Sb6 is naturally an intrinsic semiconductor with a low p-type carrier concentration. Here, we improve the thermoelectric properties of Ca5In2Sb6 by substituting Zn 2+ on the In site. With incre...

Src-specific activity has been reported to be elevated in a high percentage of colon cancer cell lines and tumors, but the underlying mechanisms are largely unknown. In this study, we report that, in the seven cancer cell lines tested, Src-specific activity was elevated (5.2- to 18.7-fold) relative to normal colon cells (FHC). This activation of Src correlated with reduced phosphorylation at Y5...

A series of anhydrous cerium(III) trifluoroacetate complexes with neutral O-donor ligands, namely Ce2(OAc)(TFA)5(DMF)3 (1), Ce(TFA)3(L)x [x = 2, L = THF (2), DMF (3), DMSO (4); x = 1, L = diglyme (5)] and Ce2(TFA)6(DMSO)x(DMF)y [x = 6, y = 0 (6); x = 4, y = 2 (7)] (where OAc = acetate, TFA = trifluoroacetate, THF = tetrahydrofuran, DMF = dimethylformamide, DMSO = dimethylsulphoxide, and diglyme...

Introduction: Brucellosis is a common zoonotic disease which has a wide spectrum of clinical manifestations and complications in humans. Brucellosis is an endemic disease in Iran. The aim of this case report was to introduce acute hepatitis as a rare complication of acute brucellosis. Case Presentation: First case, a 25-year-old man, who complained from fever, chillness, nocturnal sweating, nau...

Conditions for natural selection to increase a polygenic behavioral trait are derived for a model in which the population is divided into a very large number of partially isolated groups of variable and varying size. Specifically, we consider an altruistic trait that is deleterious to the individual but raises the mean fitness of the group. We assume, for each generation, that all groups have t...

BACKGROUND Brucella species can cause infection in a wide range of animals and human beings. Oxidative events against brucella infection are not well elucidated. It is possible that brucellosis may be related to increased free radical production and antioxidant depletion. Thus, the aim of this study was to determine the total antioxidant capacity (TAC) before and after treatment of patients wit...

BACKGROUND Brucellosis is one of the most common infectious diseases in some areas of Iran. Brucellosis has various clinical manifestations and should be considered in the differential diagnosis of many infectious and non-infectious diseases. The aims of this study were to determine the epidemiological, clinical and laboratory findings of the disease in patients with brucellosis in Hamadan, wes...

Brucellosis is a major health problem in many parts of the world, particularly in the Mediterranean and Middle East. Very few data on the frequency and diversity of haematological abnormalities occurring in brucellosis have been reported. In the present study 85 patients with brucellosis in Imam Khomeini Hospital during 1997-2002 were investigated retrospectively to determine the haematological...

OBJECTIVE To establish the role of Kv7 channels in EPAC (exchange protein directly activated by cAMP)-dependent relaxations of the rat vasculature and to investigate whether this contributes to β-adrenoceptor-mediated vasorelaxations. APPROACH AND RESULTS Isolated rat renal and mesenteric arteries (RA and MA, respectively) were used for isometric tension recording to study the relaxant effect...
