Many sensors require mechanical durability to resist immense or impulsive pressure and large elasticity, so that they can be installed in or assimilated into the outer layer of artificial skin on robots. Given these demanding requirements, we adopted natural rubber (NR-latex) and developed a new method (NM) for curing NR-latex by the application of a magnetic field under electrolytic polymeriza...

BACKGROUND Increased numbers of apoptotic neutrophils, and impaired monocyte/macrophage clearance of apoptotic cells, have been demonstrated in systemic lupus erythematosus (SLE). CD44 is implicated in the clearance of apoptotic neutrophils. OBJECTIVE To determine the expression of CD44 on peripheral blood monocytes and neutrophils in SLE, and examine the relations with disease activity and n...

Objective: Effect of methanol extract of Caralluma fimbriata (MCF) on streptatozocin (STZ) 50 mg/kg b.w. induced diabetic rats was studied. Methods: Oral administration of methanol extract of Caralluma fimbriata (MCF) to diabetic rats at a dose of 100 and 200 mg/kg body weight resulted in a significant reduction in blood glucose in STZ induced diabetic rats at different treatment period (0thday...

We investigated the effect of glucose deprivation treatment on clonogenicity in multidrug-resistant human breast carcinoma MCF-7/ADR cells. Survival of MCF-7/ADR cells decreased exponentially up to 8 hours of incubation in the glucose-free medium. The surviving fraction of these cells for 8 hours of glucose-deprivation treatment was 1.5 x 10(-3). Photomicrographs and gel electrophoresis data su...

The possibility that appropriately designed chemotherapy could act selectively against p53-defective tumor cells was explored in MCF-7 human breast cancer cells. These cells were chosen because they have normal p53 function but are representative of a tumor cell type that does not readily undergo p53-dependent apoptosis. Two sublines (MCF-7/E6 and MCF-7/mu-p53) were established in which p53 fun...

In this work, we used microwave irradiation conditions to synthesize β-enaminonitrile (4), which was affirmed using single crystal X-ray diffraction and the different spectral data. Two tumor cell lines, MCF-7 MCF-7/ADR, as well two normal HFL-1 WI-38, were assess anticancer activity of compound 4. The studied molecule exhibited potent efficacy against MCF-7/ADR lines compared with reference dr...

This study aimed to synthesis of new compounds that containing nitrogen atom and test their anticancer activity. New alkaloids have been synthesized 1H, 13C NMR, IR LC-MS thoroughly characterized. Cytotoxicity was measured against the MCF-7 human breast cell lines. The results showed better significant cytotoxic activity RU8 followed by RU6 finally RU7 cancer lines MCF-7.

Bazedoxifene (BZA) is a third-generation selective estrogen receptor modulator (SERM) that has been approved for the prevention and treatment of postmenopausal osteoporosis. It has antitumor activity; however, its mechanism of action remains unclear. In the present study, we characterized the effects of BZA and several other SERMs on the proliferation of hormone-dependent MCF-7 and T47D breast ...

A new class of murine leukemia viruses (MuLV) 1 has been designated as mink cell focus-inducing (MCF) for their ability to induce cytopathie foci when grown on mink lung fibroblasts (1). The classic MCF virus is an XC-negative, dual-tropic virus that appears to be an envelope gene recombinant between ecotropic and endogenous xenotropic viral sequences (2-7). An association between a variety of ...
