سابقه و هدف: رتینیت پیگمنتوزا (rp) نوعی از دژنراسیون های شبکیه است که بر سیگنال های چشم اثرگذار است. الکترورتینوگرام (erg) سیگنالی است که در تشخیص و پایش این بیماری نقش مهمی دارد و اطلاعاتی دارد که تنها با آنالیز آن در حوزه زمان نمی توان به آن ها دست یافت. هدف از این مطالعه بررسی تأثیر بیماری rp بر مؤلفه های زمانی، فرکانسی و زمان فرکانسی erg با استفاده از روش های پردازش تبدیل فوریه و موجک بوده ...
large areas of iran are under the influence of wind erosion thus it is important that we recognize three zones ofremoval, transportation and deposition. the deposition zone is very important due to more damages and tangibleeffects. in this study we try to obtain a comprehensive idea to persian desert with use of laboratory facilities, remotesensing, gis and field surveying. we survey 28 ergs in...
During a 2-year period, 31 cases of a hereditary retinal degeneration in dogs bred in India were found mainly suspected for progressive retinal atrophy (PRA) with typical history of initial nyctalopia followed by hemeralopia. Out of 31 PRA suspected dogs, 8 dogs (26%) were from the age group of 1-5 years, 15 (48%) 6-10 years and the rest (26%) 11-15 years. The most predominant breed was Spitz (...
هدف: این مطالعه به منظور بررسی اختلال شبکیه به وسیله الکترورتینوگرام در بیماران صرعی مراجعه کننده به درمانگاه قدس در سال 90-1389 انجام شده است. روش مطالعه: در این مطالعه مقطعی، 50 فرد بدون وجود سابقه اختلال بینایی وارد مطالعه شدند شامل 25 نفر مبتلا به صرع و 25 نفر که سالم و بعنوان گروه شاهد بودند. دو گروه تحت erg قرار گرفتند و نتایج به دست آمده در دو گروه مقایسه شدند. یافته ها: در این مطالعه،...
The microquasar MAXI J\(1820+070\) went into outburst from mid-March until mid-July 2018 with several faint rebrightenings afterwards. With a peak flux of approximately 4 Crab in the \(20-50\) keV, energy range source was monitored across electromagnetic spectrum detections radio to hard X-ray frequencies. Using these multi-wavelength observations, we analyzed quasi-simultaneous observations 12...
purpose: to present 3 rare cases of benign flecked retina syndrome. patients and finding: a 19-year-old female patient presented with fundus albipunctatus appearance in fundoscopy without night blindness and normal dark adaptation time on electeroretinography (erg). after 9 years of follow up, no change in visual acuity, erg, or other ophthalmologic examinations was seen. two members of her fam...
A step toward the molecular classification of prostate cancer was the discovery of recurrent erythroblast transformation-specific rearrangements, most commonly fusing the androgen-regulated TMPRSS2 promoter to ERG. The TMPRSS2-ERG fusion is observed in around 90% of tumors that overexpress the oncogene ERG. The goal of the current study was to complete the characterization of these ERG-overexpr...
We observed the neutron star (NS) ultra-compact X-ray binary 4U 0614+091 quasi-simultaneously in the radio band (Very Large Array), mid-infrared (IR)/IR (Spitzer/Multiband Imaging Photometer for Spitzer and Infrared Array Camera), near-IR/optical (Small and Moderate Aperture Research Telescope System), optical–UV (Swift/UV–Optical Telescope), soft and hard X-rays (Swift/X-ray Telescope and Ross...
UNLABELLED CXCR4 is a chemokine receptor that mediates invasion and metastasis. CXCR4 expression is transcriptionally regulated in cancer cells and is associated with aggressive prostate cancer phenotypes. Previously, we and others have shown that the transcription factor ERG regulates CXCR4 expression in prostate cancer cells and that androgens modulate CXCR4 expression via increasing ERG expr...
BACKGROUND ERG rearrangements in localized prostate cancer can be detected with high sensitivity and specificity by immunohistochemistry (IHC). However, recent data suggest that ERG IHC may be less sensitive for ERG rearrangements in castration-resistant prostate cancer (CRPC). Thus, we sought to examine ERG protein expression in a cohort of rapid autopsy patients with lethal metastatic CRPC (m...
