improvements in the properties of ordinary sidewall compound (nr/br) with the addition of epdm by reactive processing method were evaluated. the results show that ozone resistance of these sidewalls was improved with increased addition of epdm. also the tensile strength and elongation-at-break were increased in comparison with nrbrepdm compounds that were made by non-reactive processing. sem ph...

purpose: to evaluate changes in tear condition following unilateral ptosis surgery. methods: in this case series all patients with unilateral ptosis who underwent ptosis surgery over a two-year period were studied. the patients did not have history of previous eye surgery or other eye problems. eyelid and lacrimal evaluation included schirmer’s test with and without anesthesia and tear break up...

conclusions epidemiologic studies in kabaddi are the need of the hour to assess the burden of this predominantly rural sport and to implement injury prevention programs. our study emphasises the morbidity of knee injuries in kabaddi players of india and the exacting toll it takes on their careers. results the mean duration prior to presentation was 14.4 months. majority of the injuries (88.16%)...

Left ventricular (LV) rupture potential was studied after transmural myocardial infarction (MI) in rabbits by measuring 1) the tensile strength of infarcted tissue strips, 2) the force required to initiate a tear (tear threshold) in the central infarcted region, and 3) the intracavitary pressure required to rupture the infarcted ventricle. During the first week after MI, infarcts resulting from...

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...

Advanced glycation end products (AGEs) increase with aging and induce signaling alterations that lead to inflammation and dysfunction in several tissues. Aging reduces function and insulin signaling in lacrimal glands (LGs). To evaluate whether AGE signaling and insulin secretion in LGs are altered in aging, 24- and 2-month-old male Wistar rats were compared. Immunohistochemistry with confocal ...

The aim of this study was to evaluate the efficacy of a hyaluronic acid containing eye drop in ameliorating ocular surface pathology and discomfort in canine keratoconjunctivitis sicca (KCS). Twenty five dogs with KCS treated with a topical carbomer (CA)-based tear replacement gel were moved to treatment with a hyaluronic acid (HA)-containing tear replacement eye drop. Dogs were subject to a fu...

BACKGROUND The study sought to determine dynamic changes and theoretical bases of a clinical diagnostic test, the tear clearance rate. METHODS Thirty four healthy subjects ranging in age from 22 to 84 years underwent examination of tear clearance rate, the Schirmer test with anaesthesia, as well as fluorophotometric measurement of tear turnover, tear volume, and tear flow. By applying 0.5% fl...
