Caenorhabditis elegans embryos rapidly diversify cell fate using a modified Wnt/β-catenin signaling strategy to carry out serial asymmetric cell divisions (ACDs). Wnt-dependent ACDs rely on nuclear asymmetry of the transcriptional coactivator SYS-1/β-catenin between daughter cells to differentially activate Wnt-responsive target genes. Here, we investigate how dynamic localization of SYS-1 to m...

BACKGROUND In a correlative functional/histopathologic study, we investigated the regional deformation characteristics of both chronic nontransmural and transmural infarctions before and after a dobutamine challenge. METHODS AND RESULTS After stenosing copper-coated stent implantation to produce circumflex artery endothelial proliferation, 18 pigs were followed up for 5 weeks. Posteuthanasia ...

Objective:To study the prevalence of Dry eye disease among patients attending O.P.D. (Out Patient Department) of Assam Medical College for ophthalmic problems. Materials and Methods:-This is a prospective study conducted on 200 patients attending outpatient department of Assam Medical College & Hospital, Dibrugarh; Assam. The study was done from June,2016 to Nov,2016. This study was conducted b...

To form the proximal-distal axis of the C. elegans gonad, two somatic gonadal precursor cells, Z1 and Z4, divide asymmetrically to generate one daughter with a proximal fate and one with a distal fate. Genes governing this process include the lin-17 frizzled receptor, wrm-1/beta-catenin, the pop-1/TCF transcription factor, lit-1/nemo-like kinase, and the sys-1 gene. Normally, all of these regul...

Third eyelid covers the medial canthus of the eye and consists of T-shaped flap like cartilage and tear gland, both are helpful in protection of eye. Prolapsed gland appeared as a dark pink to reddish mass and misdiagnosed as a tumor and treated like a tumor in which gland is excised out. The present report describes a case of cherry eye (prolapse of third eyelid) in 18 months old Cocker spanie...

Motion events in language describe the movement of an entity to another location along a path. In two eye-tracking experiments we found that comprehension of motion events involves the online construction of a spatial mental model that integrates language with the visual world. In the first experiment, participants listened to sentences describing the movement of an agent to a goal location wit...

Watching slowly moving wide field-of-view patterns can cause symptoms of visually induced motion sickness (VIMS) in viewers. A within-subject full factorial experiment was designed to test two hypotheses: 1) when watching patterns rotating at 60 degrees per second (dps), eye fixation increases the peripheral retinal slip velocity leading to a reduction in the levels of VIMS; and 2) when watchin...

The purpose of this study was to investigate the differences in the ability of soccer goalkeepers to anticipate the direction of penalty kicks. Six elite goalkeepers with more than 10 years of experience participated in this experiment. Participants were required to press a reaction button as soon as they could estimate the direction of the ball while watching videos of penalty kicks. For this ...

Introduction: Despite being more affected by visual impairment and blindness than any other population age group, the elderly are least likely to seek help when faced with eye problems. Eye care utilization among the aged is influenced by a number of predisposing, enabling and need factors. Aim: To assess the eye care needs and utilization of eye care services among Ghanaian elderly population....

In this paper we present a variational formulation of the problem of determining the elastic stresses in a contact lens on an eye and the induced suction pressure distribution in the tear film between the eye and the lens. This complements the force-balance derivation that we used in earlier work [K. L. Maki and D. S. Ross, J. Bio. Sys., 22 (2014), pp. 235–248]. We investigate the existence of ...
