PURPOSE To elucidate the effect of the cotton thread test (CT-T) and Schirmer test (S-T) on the tear reservoir by evaluating the radius of tear meniscus curvature. METHODS The radii (R) of the central lower tear menisci were measured by a newly developed video meniscometer in 11 eyes of 11 normal volunteers (6 men, 5 women; mean age, 27.7 +/- 3.6 years [SD]) and 9 eyes of 9 patients with tear...

Hospitalists who teach in the clinical environment face challenges that include increased workload, perception among trainees that there is less time to teach, and competition with electronic devices for teaching engagement. In view of these and other challenges, we believe there is potentially much to gain from considering and adapting educational techniques that have been successful in nonhos...

This paper makes an econometric testing of one-minute paper used as a tool to manage and assess instruction in my statistics class. One of our findings is that the one minute paper when I have tested it by using an OLS estimate in a controlled Vs experimental design framework is found to statistically significant and effective in enhancing students’ knowledge. It is found to be equally effectiv...

purpose: to evaluate tear film status and refractive conditions during and one month after treatment of acne vulgaris with isotretinoin (accutane). methods: this prospective study was performed on 26 eyes of 13 known cases of acne vulgaris. all cases were referred by a dermatologist and were candidates for low dose isotretinoin (0.5 mg/kg). full anterior and posterior segment examination and ob...

purpose : the main ocular manifestation of rheumatoid arthritis is dry eye. lacritin is a secreted glycoprotein of tear and when applied topically in rabbits, it increased the volume of basal tear secretion. so the aim of this study was to compare lacritin level in rheumatoid arthritis (ra) and control group. methods : this cross-sectional study was done on 40 patients with ra and 48 healthy su...

Abstract A highly efficient and catalyst-free protocol is reported for the synthesis of quinoxalines via classical cyclocondensation reaction between aryldiamines dicarbonyl compounds. Remarkably simple green conditions employing methanol as solvent afforded medium to excellent yield after only one-minute time at ambient temperature. The allow least 10 gram scale should be a preferred starting ...
