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%)...
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...
Cells subjected to sustained high osmolarity almost universally respond by accumulating compatible organic osmolytes that, in contrast to inorganic ions, are not deleterious even at high intracellular concentrations. Their accumulation from the external environment by known organic osmolyte transporters, such as the four identified in mammals, occurs only slowly in response to sustained high os...
Objective: The aim of the present study was to evaluate the possible protective effect of Plantago major (P. major) extract against doxorubicin (DXR)-induced renal inflammation in rats. Materials and Methods: 80 male albino rats were randomly divided into 8 groups as follows: control, DXR, Ext (extract) 600, Ext1200, dexamethasone+DXR, vitamin E+DXR, Ext600+DXR, and Ext1200+DXR. Duration of the...
BACKGROUND Glycerol, whose formation contributes to cellular redox balancing and osmoregulation in Saccharomyces cerevisiae, is an important by-product of yeast-based bioethanol production. Replacing the glycerol pathway by an engineered pathway for NAD+-dependent acetate reduction has been shown to improve ethanol yields and contribute to detoxification of acetate-containing media. However, th...
Introduction: Ever since there is insufficient and incoherent information about the effect of the Ramadan Fasting together with regular exercise on levels of serum osmolarity, and electrolytes concentration. The aim of this study was to compare the effect of fasting and physical activity on active and non-active males’ body composition, serum osmolarity levels and some parameters of electrolyte...
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...
PURPOSE The aim of this study was to estimate the efficacy of intense pulsed light (IPL), followed by meibomian gland expression (MGX), for reducing the number and severity of signs and symptoms of dry eye disease (DED) secondary to meibomian gland dysfunction (MGD). PATIENTS AND METHODS In a prospective study conducted in two sites, 40 subjects (80 eyes) with moderate to severe MGD were enro...
the ion_ osmoregulation and salinity tolerance capabilities of juvenile acipenser persicus of different age and size groups with 90 fry for each treatment in freshwater (fw :< 0.5 ‰), estuary water (ew: 9.5 ‰) and the caspian sea water (csw: 12.5 ‰) were investigated. the fishes are directly transferred from fw to ew and csw. the possible repercussions of ion_osmoregulatory processes on some cl...
