RESUMEN
To compare the prevalence of ocular symptoms and signs in professional video-display users [VDU] and non-users. This cross-sectional case-control study was performed on bank staff who used computer for their task as the VDU group and staff who did not work with computer as controls. Ocular symptoms were evaluated based on a questionnaire and signs were detected according to complete ocular examination. The VDU group included 34 male and 23 female subjects with mean age of 30.7 +/- 6.8 years and controls included 25 male and 31 female subjects with mean age of 27.6 +/- 7.2 years. There was no statistically significant difference between the two groups regarding age and sex. Ocular symptoms included burning and tearing in 79% vs 45% [P=0.037], dry eye sensation in 66% vs 32% [P= 0.022] and asthenopia in 64.8% vs 40% [P=0.044] of the VDU group vs controls, respectively. Dry eye based on Schirmer test of less than 10 mm after 5 minutes was found in 40.3% vs 10.7% in the VDU group and controls, respectively [P=0.012]. Tear break up time of less than 10 seconds was seen in 43.8% of the VDU group and 8.9% of the control group [P=0.044]. Heterophoria was present in 33.2% of the VDU group vs 5.3% of controls [P=0.032]. There was no difference between the two groups regarding myopia [54.3% in the VDU group vs 39.2% in controls]. Ocular complaints such as burning and tearing, dry eye sensation and asthenopia were more prevalent in video-display users
RESUMEN
To determine true and apparent ileal amino acid digestibility of wheat [Mahdavi cultivar], autoclaved wheat and spaghetti by product. Completely randomized design. One hundred and twenty one - day old broiler chickens. Chickens were categorized into five groups: basal diet, bosal diet plus wheat [50: 50%], basal diet plus auto claved wheat [50:50%], basal diet plus spaghetti by product [50:50%] and protein free diet. Chromic oxide was included in all diets as an indigestible marker. Birds were fed for 7 days ad libitum and on day 35 fasted for 24 hours and then allowed to consume their respective diets for one hour. After then birds were killed by CO[2], body cavity opened, ileum removed and digesta gently flushed using strile distilled water. The apparent and true digestibility of amino acid in the test ingredients were estimated by means of basal / test diet difference method. The apparent and true amino acid digestibilities of test ingredients were significantly different [P<0.01]. Autoclaving of wheat increases its amino acid digestibilities [P<0.01]. Among test ingredients, average ileal amino acid digestibility of spaghetti by product was higher than wheat and wheat autoclaved but was lower than those values of basal diet [P<0.01]. Coefficient of amino acids digestibility within and ingredient had significant difference [P<0.01]. The difference between true and apparent values was significant [P<0.01]. Autoclaving and heat processing of spaghetti production increase wheat amino acid digestibilities. Poultry nutritionist, and broiler producers can use these digestibility coefficient values for precision feed formulation
RESUMEN
Background: anticardiolipin antibody [aCL] has been recognized as a marker for increased risk of Cerebral Vein Thrombosis [CVT]. However, there are only rare reports on CVT associated with other antibodies against different phospholipids such as phosphatidyl inositol, phosphatidyl serine, phosphatidic acid and beta 2 glycoprotein I. In this study, we studied the presence of these antiphospholipid antibodies [aPL], demographic and clinical characteristics in 30 patients with CVT
Methods: after diagnosis of CVT in 30 patients with MRI, we measured the titer of aCL and aPL [IgM and IgG] in all cases. The titers of IgG and IgM type of aPL and aCL were estimated in the sera
Results: anticardiolipin antibody was solely detected in 20% [n=6] and aCL and other aPL in 23.3% [ n=7] of patients, indicating one patient positive for other aPL but not for aCL [non-aCL]. Although the aPL positive group did not differ from the aPL-negative group from the stand point of clinical and demographic characteristics, yet seizure, infarct, superficial veins and sinus involvement and the use of OCP were seen more frequently in aPL-positive group
Conclusion: our findings suggest that in addition to aCL, other antiphospholipid antibodies may be an associated condition that plays a role in the pathogenesis of CVT. The presence of aPL in CVT patients is probably associated with more superficial sinus or veins involvement and as a result death rate was lower in aPL- positive group. Further investigations are necessary to establish this hypothesis
