Drug-induced DNA hypermethylation was observed to constitute one component of the response of human tumor cells to toxic concentrations of commonly used cancer chemotherapy agents. In both human lung adenocarcinoma cells (HTB-54) and human rhabdomyosarcoma cells (CCl-136), pulse exposures to the topoisomerase II inhibitors etoposide and nalidixic acid; to the antibiotic doxorubicin; to the micr...

BACKGROUND AND OBJECTIVES Hepatitis C virus (HCV) chronically infects around 200 million people worldwide and frequently causes liver cirrhosis and hepatocellular carcinoma. Rapid detection of this virus results in decreasing the distance between infection and initiation the anti-viral treatment, and may prevent most of the undesirable consequences. The new detected HCV protein "Core+1" made fr...

Banyaknya kebutuhan dunia pendidikan yang mengharuskan pihak pengembang aplikasi dalam mengembangkan berbagai terobosan teknologi untuk mendukung stabilitas berinteraksi. Harga Bandwitdh cukup tinggi menyebabkan sekolah melakukan pembatasan jumlah diberikan oleh operator. Semakin meningkatnya akan internet hal ini menjadi permasaalahan bagi pengguna. Permasalahannya adalah semakin banyak membuk...

BACKGROUND Four cardiac hormones i.e. atrial natriuretic peptide (ANP), vessel dilator, long acting natriuretic peptide (LANP) and kaliuretic peptide have anticancer effects in vitro. MATERIALS AND METHODS These four cardiac hormones were infused subcutaneously for 28 days with weekly fresh hormones at 3 nM min(-1) kg(-1) body weight in athymic mice bearing human breast adenocarcinomas. RES...

Proposals to enhance the amount of radiation dose delivered to small tumors with radioimmunotherapy by constraining emitted electrons with very strong homogeneous static magnetic fields has renewed interest in the cellular effects of prolonged exposures to such fields. Past investigations have not studied the effects on tumor cell growth of lengthy exposures to very high magnetic fields. Three ...

Taxanes represent a new class of antineoplastic agents that are being evaluated in several malignant tumors; they have been shown to induce a high remission rate and to prolong survival in ovarian cancer patients. However, CA-125 has been suggested to be an unreliable marker for monitoring response to paclitaxel therapy. Therefore, we were interested in whether taxanes may directly modulate CA-...

Both sorafenib and interleukin-27 (IL-27) are antineoplastic drugs. This study aimed to investigate the synergistic effect of these two drugs on bladder cancer cells. HTB-9 and T24 cells were stimulated with IL-27 (50 ng/mL), sorafenib (2 μM) or the synergistic action of these two drugs. The cells without treatment acted as control. Cell proliferation, apoptosis and invasion were measured by br...

Combining an electronic theory with molecular dynamics simulations we present results for the ultrafast structural changes in small clusters. We determine the time scale for the change from the linear to a triangular structure after the photodetachment process Ag−3 → Ag3. We show that the timedependent change of the ionization potential reflects in detail the internal degrees of freedom, in par...
