Renal cell carcinoma (RCC) metastasis to duodenum is very rare and only a few case reports are available in the literature. We here reported a patient with solitary duodenal metastasis presented with melena six years after right nephrectomy. The patient underwent upper gastrointestinal endoscopy showing ulcerative mass at the second portion of duodenum and biopsy of this mass was consistent wit...

Objective(s): The growing trend of research demonstrates that dynamic expression of two metastasis repressor classes (metastasis suppressor genes and anti-metastatic miRNA) has a close relationship with tumor invasion and metastasis. Using different strategies, it was revealed that cellular levels of miR-31 and Breast cancer Metastasis Suppressor1 (BRMS1) protein, whic...

introduction blue light is a part of the spectrum with the highest energy content, which can reach the retina. the damage that it can cause to the retina is called photochemical or blue-light retinal injury. for the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (w.m-2.sr-1) seems to be ...

Metastases to the pituitary gland are uncommon. Metastatic lesions represent < 1 % of sellar masses (1). Breast and lungs most common primary tumors associated with metastasis, representing nearly 60% cases Esophageal adenocarcinoma is a very rare cause metastasis only few have been reported. We present case patient from esophageal adenocarcinoma. 49-year-old male presented 2-month history prog...

Lymph node (LN) metastasis is considered an important prognostic factor in patients with prostate cancer. The aim of this study was to determine the rate of LN metastasis among an Iranian population who underwent radical prostatectomy (RP) with pelvic LN dissection (PLND). In a retrospective review of medical records, 450 RP cases were included and the data on LN metastasis were extracted from ...

Introduction: Choroidal metastasis is a disabling complication of several types common cancer, including breast cancer. Metastases to the choroid may present insidiously but ultimately cause significant visual disturbance and more rarely result in retinal detachment, causing sudden profound impairment. The usual treatment choice for choroidal metastases palliative radiotherapy. External beam ra...

Abstract Retinal dystrophies associated to mutations in the CRB1 gene comprise a wide array of clinical presentations. A blood sample from patient with family history CRB1-retinal dystrophy was used prepare iPSC line ESi082-A. The genotype donor, affected perifoveal-bilateral macular includes one frameshift deletion and hypomorphic allele. ESi082-A cell has been characterized for pluripotency w...

purpose : to determine the optical coherence tomography (oct) findings in eyes with idiopathic perifoveal retinal telangiectasis (ipt) methods : this study is a retrospective review of patient charts, oct, fundus photography, related to 16 eyes (11 patients). results : the most consistent finding of idiopathic perifoveal telangiectasia seen in 93.7% of eyes (15 eyes) on oct was the presence of ...

bacteriorhodopsin operates as a light/proton transfer pump which converts the light energy into a proton gradient. energy stored in the proton gradient can be used in a variety of ways. bacteriorhodopsin producing sources are some halobacterium species such as halobacterium sodomense and halobacterium salinarum which continue to grow in harsh and salt-saturated conditions. two types of red pigm...

retinal vein occlusion (rvo) is a common retinal vascular occlusive disorder and is associated with a variety of systemic risk factors. the aim of this study was to investigate whether the underlying diseases were evaluated and managed appropriately by ophthalmologists. we performed a study of 1344 patients with retinal vein occlusion (rvo). patients were evaluated with a questionnaire includin...
