Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polymorphisms to determine the association of rs4340 polymorphisms of the ...

Single crystals of SnSe were prepared in our laboratory by a special modified Bridgman technique. Measurements of the electrical conductivity and Hall effect between 141 K and 553 K were carried out on SnSe sample in two crystallographic directions. The investigated sample was found to be of p-type conductivity. The Hall mobilities parallel and perpendicular to layers plane at room temperature,...

We calculate the transverse magnetoresistance TMR and Hall coefficient RH of a three-dimensional composite medium with both positive and negative charge carriers, using the effective-medium approximation. The composite is assumed to be composed of two types of small crystallites, in which the charge carriers are either all electrons or all holes. The conductivity tensors of the two components a...

Epitaxially grown single layer and multi layer graphene on SiC devices were fabricated and compared for response towards NO2. Due to electron donation from SiC, single layer graphene is n-type with a very low carrier concentration. The choice of substrate is demonstrated to enable tailoring of the electronic properties of graphene, with a SiC substrate realising simple resistive devices tuned f...

Interband mixing between two-dimensional states localized in a surface quantum well and heavy hole states of the valence band in narrow gap semiconductor Abstract Theoretical calculations in the framework of Kane model have been carried out in order to elucidate the role of interband mixing in forming the energy spectrum of two-dimensional carriers, localized in a surface quantum well in narrow...

We measured with a radioimmunoassay the concentrations of carbonic anhydrase III (CA-III, EC 4.2.1.1) in sera from 68 patients with muscular dystrophy, 10 carriers of Duchenne muscular dystrophy (DMD), and 63 patients with other neurological disorders. The values obtained were compared with those for creatine kinase (CK, EC 2.7.3.2). Serum CA-III was strikingly increased in patients with DMD (m...

Colloidal trivalent gallium (Ga) doped zinc oxide (ZnO) hexagonal nanocrystals have been prepared to introduce more carrier concentration into the wide band gap of ZnO. The dopant (Ga) modifies the morphology and size of ZnO nanocrystals. Low content of Ga enhances the optical band gap of ZnO due to excess carrier concentration in the conduction band of ZnO. The interaction among free carriers ...

serum samples were obtained from the southern part of iran by random sampling in a health survey program. a total of 4,869 from these serum samples, 3,319 from the coastal province, 853 from khuzestan province and 697 from the ghashghai tribe were screened for the presence of hb antigen by counter electrophoresis method. on the assumption that the frequency of hb ag in a collection of healthy p...
