Cancer stem cell (CSC) markers could serve as potential prognostic procedure. This study is aimed to investigate the local expression of doublecortin-like kinase 1 (DCLK1) and Lgr5 in colorectal cancer tissues (CRC) at both protein and messenger RNA (mRNA) level, followed by providing a comparison of the local and circulating expression pattern of these markers, based on our present and previous study. The mRNA expression level of DCLK1 and Lgr5 was evaluated using comparative real-time PCR method applying 58 fresh tumor tissues and their correspondent normal margins.

Detection of cancer stem cells in circulating blood using cancer stem cell markers has received remarkable attention recently. In this study, we aimed to investigate the messenger RNA (mRNA) expression level of Lgr5 and DCLK1 as most proposed colorectal CSC markers in blood circulation also determine the subsequent association to patients' clinical and pathological findings.

Methods: In this retrospective descriptive-analytic survey during a six years period from 1998 to 2003, autopsies in the Bahrami Children Hospital, a teriary care hospital in Tehran, were studied. The clinical and autopsy diagnoses were compared and categorized as follows: 1.
Background: Many studies have investigated the variations in the anatomy of each segment of the cerebral arterial circle while a few have addressed the variations of the cerebral arterial circle as a whole.
Methods: Thirty brains of recently deceased Iranian infants and fetuses were dissected. The dissection process was filmed and digitized so as to be readily available for further studies.
Aim: In recent years several studies have shown increasing rate of upper gastric cancers regarding to decrease in distal gastric cancers. The aim of this study was to describe the trend of gastric cancers by location in Iran, which is one of the countries with high prevalence of gastric cancers.
Methods: All registered cases of gastrectomy in Tehran Cancer Institute from 1969 through 2004 were re-evaluated clinicopathologically.
