background: leishmaniasis is a tropical disease that is endemic in some areas of iran, including east azerbaijan . ifn-γ is one of the cytokines that triggers cell-mediated immunity, thus initiating elimination of the infection. this case-control study was performed to investigate the association between the polymorphism of the ifn-γ gene at the +874a/t locus and visceral leishmaniasis (vl). me...

scid is a lethal genetic autosomal recessive disorder that has been observed in humans, dogs, mice, and horses. affected animals are incapable of generating specific antigens for immune responses needed to protect them from infectious diseases. the frequency of affected recessive allele varies in different regions so that the outcome of normal breeding with carriers of recessive alleles is diff...

A method to detect and manage collision situations of the concurrent operations made by two robot arms in a shared work space is presented. Two different strategies, collision avoidance and in-turns operation are considered. The operation of a dual-armed assembly robot is modeled using Petri nets. The model is then tested by the means of an animated virtual assembly system. By observing the ope...

Utilizing theory of the secondary quantization, a study of vibration behaviors in flexible-link robot arms is possible in microscopic viewpoints. This paper studies the relation of vibration related to phonon coupling interaction by means of Green’s function method beginning with energy model. Results confirm analytically the existence of the relationship between the macroscopic study employing...

We determined muscle attachment points for the index, middle, ring and little fingers in an OpenSim upper-extremity model. Attachment points were selected to match both experimentally measured locations and mechanical function (moment arms). Although experimental measurements of finger muscle attachments have been made, models differ from specimens in many respects such as bone segment ratio, j...

Analyzing the (l, b, V LSR) data cube of 13 CO(J = 1 − 0) line emission obtained by Bally et al, we have investigated the molecular gas distribution and kinematics in the central ±1 • (±150 pc) region of the Galaxy. We have applied the pressing method to remove the local-and foreground-gas components at low velocities in order to estimate the intensity more quantitatively. Two major dense molec...

OBJECTIVES To evaluate morbidity associated with the radial forearm free flap donor site and to compare functional and aesthetic outcomes of ulnar-based transposition flap (UBTF) vs split-thickness skin graft (STSG) closure of the donor site. DESIGN Case-control study. SETTING Tertiary care institution. PATIENTS The inclusion criteria were flap size not exceeding 30 cm(2), patient availab...

PURPOSE This study aimed to identify potential epidermal growth factor receptor (EGFR) gene mutations in non-small cell lung cancer that went undetected by amplification refractory mutation system-Scorpion real-time PCR (ARMS-PCR). MATERIALS AND METHODS A total of 200 specimens were obtained from the First Affiliated Hospital of Guangzhou Medical University from August 2014 to August 2015. In...
