Hydrogen sulfide (H(2)S), a colorless gas with a characteristic smell of rotten eggs, has been portrayed for decades as a toxic environmental pollutant. Since evidence of its basal production in mammalian tissues a decade ago, H(2)S has attracted substantial interest as a potential inorganic gaseous mediator with biological importance in cellular functions. Current research suggests that, next ...

A great number of intraocular lenses various models and manufacturers is present on the ophthalmic market. The difficulty lies in choosing a specific lens model for each eye. In this work, we compare characteristics some monofocal IOLs most often implanted Orenburg branch S. Fyodorov Eye Microsurgery Federal State Institution over past 5 years, as well results their implantation economic compon...

This paper examines several contributors to eye diagram degradation in high-speed digital systems. The eye diagrams are generated through a combination of full wave simulation and circuit analysis. The interconnect part of the analyzed structure is first characterized in terms of S parameters obtained with the finite difference time domain (FDTD) method. The resulting S parameters are used toge...

Background: Computer usage has rapidly grown. This is because it helps to resolve problems, i.e., encountered in daily life by individuals. Various monitor screens that have been developed affect the userchr('39')s eyes. Screen size is one of the relevant impacts. Thus, this study compared the immediate effects of two computer screen sizes on visual fatigue in Video Display Terminal (VDT) users...

During animal development, cell proliferation is controlled in many cases by regulation of the G1 to S phase transition. Studies of mammalian tissue culture cells have shown that the G1-specific cyclin, cyclin E, can be rate limiting for progression from G1 to S phase. During Drosophila development, down-regulation of cyclin E is required for G1 arrest in terminally differentiating embryonic ep...

Purpose: To report a case of branch retinal artery occlusion (BRAO) in a pregnant patient of Chinese descent found to have Protein S deficiency. Case report: A 35 year-old apparently healthy, pregnant female of Chinese origin reported in the eye clinic of our hospital with a complaint of sudden appearance of a “shadow” in the periphery of her left eye for the last three days. On examination, sh...

Receptive field properties of single neurons in the cat superior colliculus were examined following selective conduction-block of Y-type fibers in contralateral optic nerve. Although the responses evoked by photic stimuli presented via the Y-blocked eye were significantly weaker than those evoked by stimuli presented via the normal eye, >85% of collicular cells were binocular. Furthermore, when...

Studies have revealed superior face recognition skills in females, partially due to their different eye movement strategies when encoding faces. In the current study, we utilized these slight but important differences and proposed a model that estimates the gender of the viewers and classifies them into two subgroups, males and females. An eye tracker recorded participant's eye movements while ...

Changes in sensitivity of the photoreceptor cells of the anterior median eye of the jumping spider Menemerus confusus Boes. et Str. have been studied by recording electroretinograms (ERGs) and receptor potentials. The amplitudes of the responses (ERGs and receptor potentials) increase during repetitive stimulation, with a maximum increase at 3-5 s intervals. The sensitivity of the photoreceptor...
