The epidemiology, aetiology, clinical features, diagnosis, and treatment of Crohn’s disease and ulcerative colitis in children are reviewed, and areas for further research identified. (Arch Dis Child 2001;85:435–437)

Diarrheal disease is one of the main causes of death in developing countries. This study was performed to the prevalence of bacterial causes of diarrhea in patients admitted to the Military hospitals and Imam Khomeini Medical Center Hospital. This cross-sectional study was conducted in a period of 9 months from June 2014 to February 2015, 435 non-duplicative diarrheal stool samples were collect...

Background: Tuberculosis (TB) is a major cause of death worldwide. Finding an effective vaccine against TB is the best way to control it. Several vaccines against this disease have been developed but none are completely protective. The aim of this study was to design and construct a cloning vector containing the Mycobacterium tuberculosis (M. tuberculosis) heat shock protein X (hspX). Metho...

We used a screening procedure to identify protein domains from phage-displayed cDNA libraries that bind both to bone marrow endothelial progenitor cells and tumor vasculature. Screening phage for binding of progenitor cell-enriched bone marrow cells in vitro, and for homing to HL-60 human leukemia cell xenograft tumors in vivo, yielded a cDNA fragment that encodes an N-terminal fragment of huma...

Activation and signalling of estrogen receptor (ER) and COX-2 represent two important pathways in breast cancer cell regulation. Activation of either pathway is associated with breast cancer cell proliferation and eventually malignant progression. Raloxifene analogue, Ly117018, a selective estrogen receptor modulator and celecoxib, a specific COX-2 inhibitor have been shown to inhibit breast ca...

We have investigated the regulation of adhesion of metastatic human breast carcinoma cells to various protein substrates in the presence or absence of the protein kinase C (PKC) activator, 12-tetradecanoyl phorbol 13-acetate (TPA) or calcium ionophore A23187 (A23187). Both TPA and A23187 dramatically enhanced MDA-MB-435 cell adhesion to type IV collagen (collagen IV), vitronectin, and, to some ...

Secondary to the increased survival following chemotherapy, brain metastases have recently become a significant clinical problem for breast cancer patients. The aim of this study was to characterize those functional phenotypes that might enhance brain metastasis in breast cancer cells. We first analyzed by two-dimensional electrophoresis (2DE-DIGE) differences in protein expression between pare...

A radioiodinated derivative of the tumor-homing F3 peptide, (N-(2-{3-[(125)I]Iodobenzoyl}aminoethyl)maleimide-F3Cys peptide, [(125)I]IBMF3 was developed for investigation as a SPECT tumor imaging radioligand. For this purpose, we custom synthesized a modified F3 peptide analog (F3Cys) incorporating a C-terminal cysteine residue for site-specific attachment of a radioiodinated maleimide conjugat...
