Prostatic ductal adenocarcinomas may arise either in large primary periurethral prostatic ducts or in the peripheral prostatic ducts. Ductal adenocarcinomas are composed of tall columnar cells arranged in cribriform, papillary, solid, single glands, and PIN-like patterns. Other than the prostatic intraepithelial neoplasia (PIN)-like ductal pattern, which behaves like Gleason pattern 3, ductal a...

The prognostic significance of Paneth cell-like neuroendocrine differentiation in adenocarcinoma of the prostate has not yet been established. We studied 36 cases of adenocarcinoma of the prostate showing Paneth cell-like neuroendocrine differentiation, including needle biopsy specimens (n = 27), radical prostatectomies (n = 8), and transurethral resection specimens (n = 1). Paneth cell-like ne...

Linear assemblies of nanoparticles show promising applications due to their collective electronic, optical and magnetic properties. Rational design and controllable organization of nanoparticles in one-dimensional structures can strongly benefit from the marked similarity between conventional step-growth polymerization reactions and directional step-wise assembly of nanoparticles in linear chai...

PURPOSE To describe the intraoperative staining pattern of the internal limiting membrane (ILM)-specific dye Brilliant Blue G (BBG) in a cohort of patients with idiopathic macular holes; to analyze the associations of the staining pattern with pre- and postoperative variables and to correlate the staining pattern with transmission electron microscopy (TEM) of the excised ILM. METHODS Fifty-fi...

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Recent studies of the genetic structure of stream-dwelling organisms have suggested that ®ne-scale patterns are the consequence of patchy recruitment from a small number of matings and limited in-stream dispersal. Predictions of this hypothesis were tested by spatial and temporal analysis of the genetic structure of populations of a stream may ̄y (Bungona sp.: Baetidae) in subtropical streams in...

A 68 years old man with prostate carcinoma was referred for 68Ga-PSMA PET/CT scan because of recent significant rise of PSA. He complained of muscle weakness and fatigue, since 3 weeks before the scan, without dyspnea or shortness of breath. In his 68Ga-PSMA-611 PET/CT study, widespread skeletal metastasis, as well as liver involvement were noticed. Also, multiple bilatera...
