the appearance of one’s hair is central to feelings of attractiveness and selfesteem
for many, so the disturbance in this appearance will reflect upon the psychosocial aspects of the
patient and thus on the quality of his life. The androgenetic alo
pecia (male pattern baldness) is the most
common cause of hair loss in men, as it affects about 50% of adult men, so it may be considered the
biggest threat in this aspect, but there are no epidemiological studies that study the actual effect of
androgenetic alopecia on the quality of life of the patients in Syria.
study the effect of the androgenetic alopecia on quality of life of the Syrian male patients.
Multitiered ecommerce applications are distributed applications where
application logic is divided into components according to function. These
components are installed on different machines, depending on the tier to
which the application component belongs , additionally, these
applications provide ecommerce services like online shopping
A new carbon paste electrode (CPE) for Co2+ ion modified with
complex of Cobalt(II) with 1-(2-pyridylazo)-2-naphthol (PAN) as
electroactive 84aterial was prepared. The best performances were
obtained by carbon paste electrode with the composition Graphit
powder (47%), DOPH as plasticizer (47%) and Co-PAN as
electroactive material (6%)
Aim: to determine the value of RNFL thickness at which visual field defect becomes
detectable.
Methods: Our study included 29 normal subject and 36 glaucomatous patient (one
eye per person) .Every person was examined by OCTOPUS perimetry with glau
coma 30-2
program, and peripapillary RNFL thickness was measured by HIEDELBERGSPECTRALIS
SD_OCT.
Results: comparison of results showed higher sensitivity of OCT compared to
Perimetry. Mean RNFL thickness at which visual field defect showed was 87 microns.
Superior RNFL thickness value which correlated with inferior visual field defect was 101
microns, whereas inferior RNFL thickness value which correlated with superior visual
field defect was 75 microns .and the difference in RNFL thickness between normal and
glaucomatous visual field was significant (p<0.001).
Conclusion: in open-angle glaucoma , it needs significant thinning in RNFL before
visual field defects becomes detectable.
Selenium is an essential nutritional mineral, and selenium deficiency diseases are known in medical literature. Studies have shown that selenium intake in high doses is toxic in humans. Selenium is widely distributed in nature and due to the importan
ce of selenium and its compounds in industrial applications; several analytical techniques have been reported to estimate selenium. In this study the optimal conditions for the formation of selenium complex with NEDA reagent will be studied and used for the control of selenium microcapsules, a method that is characterized by being rapid, sensitive and selective. The optical spectrophotometric method was used in the visible field at 540 nm wavelength to determine the complex between the selenium ion and the NEDA reagent under optimal conditions for complex formation namely temperature 50℃, time min t = 240, added reagent volume V=4ml, and reagent concentration 1%. This method showed good accuracy and correctness, as the method's validity was achieved through the relative percentage yield (R = 99.68%), while the accuracy of the method was achieved through the low value of the standard deviation (SD≤) (1.172) and thus the percentage relative standard deviation (RSD≤) (1.725). Selenium microcapsules were prepared, with an entrapment efficiency of 36% at a concentration of 3% for alginate and 1% while the entrapment efficiency rose to 51.2% at a concentration of 2% for calcium chloride.
