Enhancement of EFS-induced contractions, by agmatine, in guinea pig gallbladder smooth muscle strips
(SPRINGER TOKYO, 2005)
Background. Electrical field stimulation of gallbladder muscle strips produces frequency-dependent contractions by activating cholinergic nerves. The cholinergic motor function of the gallbladder and enteric system is also ...
Tunable long-wavelength broad band asymmetric quantum well infrared photodetector
(IOP PUBLISHING LTD, 2007)
We present a theoretical investigation of a GaAs/AlGaAs infrared detector consisting of three asymmetric quantum wells. Each well is designed to yield absorption and a photoresponse at peak wavelengths of 8.2 mu m, 9.5 mu ...
Intersubband transitions in coupled triple-graded quantum wells under an electric field
(WILEY-V C H VERLAG GMBH, 2005)
The intersubband transitions were calculated in three different shaped triple-graded quantum wells. The investigation involved changing the depth of the central well potential under an electric field applied parallel to ...
Comparison of the diagnosis of plain radiography ultrasonography and magnetic resonance imaging in early diagnosis of acute osteomyelitis experimentally formed on rabbits
(ELSEVIER IRELAND LTD, 2005)
Purpose: We have compared the sensitivities of MRI, US and radiography which are some of the radiologic modalities used in the early diagnosis of acute osteomyelitis. Materials and methods: After 1 week care and research ...
Uranyl ion binding properties of poly(hydroxamic acid) hydrogels
(SPRINGER-VERLAG, 2001)
Poly(hydroxamic acid) (PHA) hydrogels, obtained from the synthesis of crosslinked poly(acrylamide) (PAAm) gels have been prepared, and their uranyl ion binding properties from two different sources were investigated. ...
Adsorption of bovine serum albumin onto radiation-crosslinked poly(acrylamide/acrylic acid)
(MULTI SCIENCE PUBL CO LTD, 2004)
Poly(acrylamide/acrylic acid) (AAm/AAc) hydrogels were prepared at initial acrylic acid compositions of 70, 80 and 85 mol%, respectively. Mixtures of AAm and AAc monomers were irradiated in a Co-60 gamma-ray source at a ...
Magmatic processes and mixing origin of andesite: Miocene Karamagara volcanics, central Anatolia, Turkey
(WILEY-BLACKWELL, 2005)
The Miocene Karamagara volcanics (KMV) crop out in the Saraykent region (Yozgat) of Central Anatolia. The KMV include four principal magmatic components based on their petrography and compositional features: basaltic ...
Ocular Findings in Patients with Crimean-Congo Hemorrhagic Fever
(ELSEVIER SCIENCE INC, 2009)
PURPOSE: To describe ocular findings of patients with Crimean-Congo hemorrhagic fever (CCHF). DESIGN: Prospective, interventional, consecutive case series. METHODS: This study was conducted in Sivas, a city located in the ...
Relationship between capillary angiogenesis, fiber type, and fiber size in chronic systemic hypoxia
(AMER PHYSIOLOGICAL SOC, 2001)
Whether chronic hypoxia causes angiogenesis in skeletal muscle is controversial. Male Wistar rats, 5-6 wk of age, were kept at constant 12% O-2 for 3 wk, and frozen sections of their postural soleus (SOL), phasic extensor ...
Viscometric investigation of compatibilization of the poly(vinyl chloride)/poly(ethylene-co-vinyl acetate) blends by terpolymer of maleic anhydride-styrene-vinyl acetate
(ELSEVIER SCIENCE BV, 2008)
In this study, a blend of poly(vinyl chloride) (PVC)/ethylene-co-vinyl acetate (EVA) was compatibilized by terpolymer of maleic anhydride-styrene-vinyl acetate (MAStVA) used as a compatibilizer. It was prepared the blends ...
