The value of fine-needle aspiration cytology in salivary gland lesions, 1994-2004
(KARGER, 2007)
Objective: Fine-needle aspiration cytology (FNAC) of the salivary gland is a commonly accepted, sensitive and specific technique in the diagnosis of both neoplastic and nonneoplastic lesions of the salivary gland. The aim ...
Studies on the antioxidant activity of the essential oil and methanol extract of Marrubium globosum subsp globosum (lamiaceae) by three different chemical assays
(ELSEVIER SCI LTD, 2008)
This study is designed to examine the chemical composition and in vitro antioxidant activity of the essential oil and sub-fractions of the methanol extract of Marrubium globosum subsp. globosum. The GC and GC-MS analysis ...
Contrast medium-enhanced MRI findings and changes over time in stage I tuberculous meningitis
(W B SAUNDERS CO LTD, 2007)
AIM: To demonstrate the detailed imaging characteristics of early tuberculous meningitis (TBM) and changes over time on standard gadolinium-enhanced, T1-weighted magnetic resonance imaging (MRI) images. MATERIALS AND ...
In Vitro Amoebicidal Activity of Salvia staminea and Salvia caespitosa on Acanthamoeba castellanii and Their Cytotoxic Potentials on Corneal Cells
(MARY ANN LIEBERT, INC, 2009)
Background/Aims: Amoebic keratitis is difficult to treat with total efficacy in some patients because of cysts, which are less susceptible than trophozoites to the usual treatments. We investigated the in vitro effectiveness ...
Optical intersubband transitions in double Si delta-doped GaAs under an applied magnetic field
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
For different applied magnetic fields, the intersubband transitions of double Si delta-doped GaAs structures is theoretically investigated for a uniform donor distribution. The electronic structure has been calculated by ...
Ground state energy of excitons in quantum dot treated variationally via Hylleraas-like wavefunction
(IOP PUBLISHING LTD, 2009)
In this work, the effects of quantum confinement on the ground state energy of a correlated electron-hole pair in a spherical and in a disc-like quantum dot have been investigated as a function of quantum dot size. Under ...
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 ...
