introduction: patients with bilateral weakness (bw) have many difficulties in gaze stability that interfere with their normal function. the aim of this study was to evaluate ocular motor functions in patients with bw to better understand the problem of gaze instability in these patients.   materials and methods: patients were referred from the otolaryngology department for vestibular assessment...

The vertebrate eye is a highly specialized sensory organ, which is derived from the anterior neural plate, head surface ectoderm, and neural crest-derived mesenchyme. The single central eye field, generated from the anterior neural plate, divides to give rise to the optic vesicle, which evaginates toward the head surface ectoderm. Subsequently, the surface ectoderm, in conjunction with the opti...

to measure soil water content (or soil matric suction) in thin layers of about 30mm, conventional gypsum blocks are not suitable. to carry out the task, mini-gypsum blocks were constructed using plaster of paris in an innovative fashion. a power relationship was found between the soil water content and the mini-gypsum blocks’ readings in kω. the calibration results showed that readings of m...

PURPOSE To evaluate the feasibility of developing a novel mini drug pump for ophthalmic use. METHODS Using principles of microelectromechanical systems engineering, a mini drug pump was fabricated. The pumping mechanism is based on electrolysis, and the pump includes a drug refill port as well as a check valve to control drug delivery. Drug pumps were tested first on the benchtop and then aft...

Nowadays, there is no effective treatment for many retinal disorders. Knowledge of the genetic basis of many severe ocular diseases may allow for alternative treatments by gene therapy. Non-viral gene complexes, such as lipo- and poly-plexes, can be delivered to the posterior segment, most often the target tissue, by intravitreal or subretinal injection. Since subretinal injections are very inv...

Community development efforts associated with the reduction in poverty and injustice historically have not benefited from the productivity and efficiency as well as private industry and government. Recently, declining entry barriers and Web ubiquity has spurred IS use for community development. This mini-track is designed to explore those uses and to encourage additional thoughts and models for...

(1) Works listed in the Sheet Music Consortium had more views/work than those not listed. (2) Works at the top of the Sheet Music Consortium browse list had more views by Consortium users than those lower down. (3) Works with cover graphics had more views/work than those with covers containing words alone. (4) Works included in mini-collections received more views/work from users with access to...

Abstract Evaluating the effectiveness of different bone conduction (BC) transducers with controlled coupling force to elicit cervical and ocular vestibular evoked myogenic potentials (cVEMPs, oVEMPs) in healthy subjects by comparing response rates, amplitudes, latencies, thresholds asymmetry ratios. Prospective experimental study including participants. VEMPs were measured stimulation modes; BC...

background: recently, some new viruses have been identified for their association with hepatitis which torque teno mini virus being among them. the aim of this study was to determine the frequency of torque teno mini virus in healthy individuals and hepatitis b and c patients in isfahan, iran. materials and methods: one hundred serum samples of healthy individuals from isfahan blood transfusion...

Given the importance of potato in the economy and people’s nutrition, as well as planting of disease-free seeds, it seems necessary to produce healthy seeds through tissue culture. This study was conducted during 2012-2013 at the Research Center of Agricultural University of Tajikistan aiming to evaluate the effect of different sizes of mini-tuber on yield and yield components of potato crop. A...
