The purpose of this study is to determine the safety and efficacy of VSF-173 compared to placebo in treatment of induced excessive sleepiness.
Functional properties of chitooligosaccharides have been studied for antitumor activity, immunostimulating effects, antimicrobial activity, free radical scavening activity, adn angiotensin I converting enzyme inhibitory activity. Recent in vitro, and in vivo toxicity and absorbability studies have demonstrated that chitooligosaccharides have high absorbability and are essentially non-toxic. In the present study, we prepared a chitooligosaccharide with high absorbability and evaluated its effects on activation of immune function and cardiovascular funciton(lipid, atrial stiffness, etc) in healthy adults. This study was a 8-week, randomized, double-blind clinical trial. The 30 volunteers were divided into a control group(n=10), half dose chitooligosaccaride(FACOSTM) intake group(n=10), and full dose FACOS intake group(n=10). Peripheral blood mononuclear cells(PBMCs) were isolated and cultured in 12 well plate for 48 hours. Cytokine production by PBMCs pre- and postintervention were measured simultaneously after stimulation with lipopolysaccaride.

Titanium Sapphire laser trabeculoplasty is effective in lowering intraocular pressure in glaucoma patients, and is comparable to argon laser trabeculoplasty
Purpose: To investigate the efficacy of photodynamic therapy with verteporfin for the treatment of patients with corneal neovascularization. Design: Prospective, non-comparative case series. Participants: Eighteen eyes of 18 patients with stable corneal neovascularization who were refractory to conventional treatment. Methods: The patients were treated with photodynamic therapy with verteporfin (6 mg/m2). Five patients were treated following penetrating keratoplasty, and 2 patients were treated before penetrating keratoplasty. Best corrected visual acuity and anterior segment photography were performed before and after treatment. The length of cumulative blood vessels and area of corneal neovascularization were measured. Main outcome measures: Vascular occlusion, best corrected visual acuity, cumulative blood vessel length, and corneal neovascularization area.
The purpose of this study is to determine the ability of several eye movement monitors, used in clinical practice, to identify children with poor reading eye movements. A second purpose of the study is to evaluate the effectiveness of eye movement therapy.
Attention-Deficit Hyperactivity Disorder (ADHD) is considered to be one of the most prevalent chronic health conditions in children. It affects between 4% and 12% of young children. A relationship between convergence insufficiency (eye teaming) and ADHD has been shown. However, the effect of ADHD medications on focusing and eye teaming has not been previously investigated. Therefore, the purpose of this study is to determine the effect of ADHD medication on focusing and eye teaming skills.
The goal of this study is to compare the effectiveness of the administration of sequential drops, a combination drop and a combination spray for producing mydriasis and cycloplegia.
This is a randomized trial to compare the effect of standard versus enhanced risk reduction counseling on risk behavior incidence in individuals receiving PEP medications. The study seeks to 1) determine if there are equivalent changes in the incidence of self-reported risk behaviors, STD incidence, and adherence to medications in individuals who receive enhanced risk reduction and adherence counseling and those who received standard risk reduction and adherence counseling; 2) evaluate viral and host biological factors involved in sexual transmission that may either influence PEP efficacy, or themselves be negatively or positively affected by the administration of PEP medications; and 3) contribute to the CDC registry in an attempt to provide crucial data for a case control analysis to establish the efficacy of PEP for sexual and injection drug use exposures. The principal outcome will be the change in participants' number of unprotected sexual acts following administration of PEP. This is defined as the number of prior 3-month acts of high risk unprotected sex, assessed at 12 months following a course of PEP, minus the number of unprotected acts the participant reported in the 3 and 6 months prior to beginning PEP (assessed at baseline). Methods to be used consist of interview data collection, questionnaires, risk reduction and adherence counseling and source recruitment counseling (index subject).
The aim of this study is to find out how well iron is absorbed when a newly developed form of ferric pyrophosphate is added to a commercial apple juice drink.
