BACKGROUND In light of the recently found contribution of angiogenic and inflammation-related factors to malignancies, this study investigated the possible association of the angiotensinogen gene (AGT) with increased risk of oral cancer. MATERIALS AND METHODS The M235T polymorphism, which influences AGT gene expression, was evaluated by restriction fragment length polymorphism analysis in the...
background: foot -and- mouth disease (fmd) is endemic in iran. molecular techniques for diagnosis of persistent infection or carrier animals have shown a potential ability to improve the detection of a low genome copy number in samples. objectives: the purpose of this study is to evaluate the frequency of foot and mouth disease viral carriers in slaughtered sheep in mashhad industrial abattoir ...
Abstract Background Parkinson’s disease is one of the neurodegenerative disorders that caused by genetic and environmental factors or interaction between them. Solute carrier family 41 member 1 within PARK16 locus has been reported to be associated with disease. Cognitive impairment non-motor symptoms considered a challenge in patients. This study aimed investigate association rs11240569 polymo...
Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...
BACKGROUND A dead region is a region in the cochlea where the inner hair cells and/or neurons are functioning very poorly, if at all. We have shown that, for people with sensorineural hearing loss, thresholds for detecting sinusoidal amplitude modulation (AM) of a sinusoidal carrier were lower for ears with high-frequency dead regions, as diagnosed using the threshold-equalizing noise test, cal...
In a GPS receiver, the goal of the signal tracking is to synchronize local generated code and carrier with the received signal. After a step of acquisition, the receiver tracks the shifting of the local code provoked by the movements of the receiver and satellites. In the future evolution of the GPS, the system will have several carrier frequencies, then it will be possible to have several trac...
Source/Description: We recently found a new polymorphism in the CYP1A1 gene by PCR direct sequencing (1) which results in amino acid substitution of De for Val at residue 462 in the heme binding region of the P450IA1 protein. This polymorphism asociates with Mspl polymorphism (2, 3) in the 3'-flanking region, and the linkage disequilibrium is calculated to be 0.158 (1). Here we report the PCR d...
Thresholds for detecting interaural phase differences (IPDs) in sinusoidally amplitude-modulated pure tones were measured in seven normal-hearing listeners and nine listeners with bilaterally symmetric hearing losses of cochlear origin. The IPDs were imposed either on the carrier signal alone-not the amplitude modulation-or vice versa. The carrier frequency was 250, 500, or 1000 Hz, the modulat...
