Mice lacking retinol-binding protein (RBP) have low circulating retinol levels. They have severe visual defects due to a low content of retinol or retinyl esters in the eye. A transgenic mouse strain that expresses human RBP under the control of the muscle creatine kinase promoter in the null background was generated. The exogenous protein bound retinol and transthyretin in the circulation and ...

Normal eye color of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is darkpurplish-black.A strainhomozygous for anewmutation, redeyecolor,wasestablishedandreared in the laboratory for 5 yr. Themutant phenotype is controlled by a single autosomal recessive allele. The gene symbol assigned to this new mutant is r. Laboratory tests showed that egg production and egg viability in ...

eye movement desensitization and reprocessing (emdr) process encompasses several nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes. the role of eye movement (em) has been documented previously in relation with cognitive processing mechanisms. by emdr we can reach some parts of memory which were inaccessible before and als...

In the IT sector, employees use systems for more than 6 hs, so they are affected by many health problems. Mostly with eye diseases like strain, pain, burning sensation, double vision, blurring of and frequent watering. The major goal this research is to identify different types problems encountered, symptoms present, population afflicted in order accurately forecast outcomes using a Machine lea...

Proposed is a novel eye vision testing system based on micromachines that uses micro-optic, micromechanic, and microelectronic technologies. The micromachines include a programmable micro-optic lens and aperture control devices, pico-projectors, Radio Frequency (RF), optical wireless communication and control links, and energy harvesting and storage devices with remote wireless energy transfer ...

Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...

We propose a novel method to avoid stereo window violations at screen borders. These occur for objects in front of the zero parallax plane, which appear (physical) screen, and that are clipped one eye while still being visible other eye. This contradicts cues, particularly disparity, potentially resulting strain simulator sickness. In interactive dynamic virtual environments, where user control...

background: heat stress is a common and usual problem in industries. several indices, including wet bulb globe temperature (wbgt), are used to evaluate heat stress. however, wbgt index has limitations such as high cost and response time. it is not thus suitable as a screening tool. heat strain scoring index (hssi) is also an observational-judgmental technique that has been developed for primary...

IMPORTANCE Eyes of patients with glaucoma may be damaged during sleep. OBJECTIVE To measure strains in glaucoma eyes and control eyes produced by mechanical force or deformation of the eye from contact when one side of the face rests against a pillow. DESIGN, SETTING, AND PARTICIPANTS This study took place in a clinic-based setting among 22 patients with glaucoma and 11 age-matched controls...
