Context Effects In Visual Length Perception: Role Of Ocular, Retinal, And Spatial Location, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

In three experiments, we examined the transfer of orientation-contingent context effects between the eyes and across portions of the retina with or without variation in external spatial location. Previous research had shown that vertical lines are judged long, relative to horizontal lines, when the stimulus set comprises relatively long horizontals and short verticals (Contextual Condition B), as compared with the reverse when the stimulus set comprises relatively short horizontals and long verticals (Contextual Condition A). Consequently, the contextual set of stimuli influences the magnitude of the horizontal-vertical illusion (HVI), decreasing its size under Contextual Condition A and increasing its size …

Prevalence Of Various Upper Extremity Disorders In Patients With Carpal Tunnel Syndrome Versus Patients Without Carpal Tunnel Syndrome, Daniel C. Buda

Loma Linda University Electronic Theses, Dissertations & Projects

Background and Purpose: Increasingly larger numbers of patients present with repetitive strain injuries of the upper extremities, especially carpal tunnel syndrome (CTS). A large number of these patients appear to have more than one upper extremity condition. The purpose of this study was to determine the probability that a patient diagnosed with carpal tunnel syndrome will also be diagnosed with other upper extremity and/or cervical spine disorders.

Subjects: A group of 188 subjects diagnosed with carpal tunnel syndrome and a group of 203 subjects without carpal tunnel syndrome were selected through a chart review of patients at Loma Linda …

Pkcα Translocation And Actin Remodeling In Contracting A7r5 Smooth Muscle Cells, Chenwei Li

Theses, Dissertations and Capstones

Recent research indicates that protein kinase C (PKC) plays an important role in smooth muscle contraction. Because PKC activation and specificity of substrate phosphorylation is believed to be associated with the relocalization of the enzyme to specific cell sites, we first investigated the subcellular translocation of PKCα in A7r5 smooth muscle cells by confocal microscopy through use of standard immunohistologic staining and PKCα - enhanced green fluorescent protein (PKCα -EGFP) fusion protein expression. PKCα was diffusely distributed throughout the cytosol in the unstimulated A7r5 cell. Upon stimulation with phorbol 12, 13 dibutyrate (PDBu), PKCα was translocated primarily to either the …

Polymerase Chain Reaction: An Emerging Tool For Research In Pharmacology, Rishi Sharma, Manjeet Singh, Ajay Sharma

Pharmacy Faculty Articles and Research

Polymerase chain reaction (PCR) is a technique that can amplify a specific DNA segment in vitro using two site specific primers that hybridise to opposite DNA strands. The method produces large amounts of specific DNA from a complex DNA template in a single enzymatic reaction within a matter of hours. Reaction mixture contains a double helix DNA, two target specific primers, dNTPs, a DNA polymerase and a Mg2+ containing buffer. PCR is carried out in three distinct steps i.e. denaturation step, annealing step and extension step, which are repeated many times. The efficiency of PCR is measured in terms of …
