Although chemotherapy of tumours has scored successes, drug resistance remains the major cause of death of cancer patients. Initial treatment often leaves residual disease, from which the tumour regrows. Eventually, most tumours become resistant to all available chemotherapy. I call this pan-resistance to distinguish it from multi-drug resistance, usually describing resistance caused by upregul...

purpose : to investigate the correlation between corneal biomechanical properties and tomographic parameters of pentacam methods : corneal biomechanical properties and tomographic results of 36 normal subjects were measured by ocular response analyzer (ora) and pentacam and the correlation between these two measurements were analyzed with pearson correlation test with spss version16. results : ...

CD133 has been postulated to be a colon cancer stem cell (CSCs) marker. Recent investigations suggest that CSCs might contribute to cancer recurrence and resistance to conventional therapies. This study aimed to evaluate the role of CD133 in residual cancer cells after chemoradiotherapy (CRT) for rectal cancer. Forty patients with rectal cancer underwent CRT followed by surgery. Total RNAs of r...

in this research resistance of six tree species to logging damages (bole wound) after 12 years were studied in district 1 of asalem nav forests. the data of extent and severity of damages on residual trees were collected immediately after logging operation from systematic sampling with circular 0.1 ha plots in the year of 2000. the damaged trees and wounds condition were reexamined in the year ...

Two distinct models account for the microwave residual surface resistance of superconducting cavities with equally good agreement with the measured temperature and frequency dependence. In presenting his phonon generation model, Passow claimed that Rabinowitz’s fluxoid power loss model of residual resistance does not fit the experimental data, whereas his does. In fact, the two models have esse...

BACKGROUND Malaria vector control is threatened by resistance to pyrethroids, the only class of insecticides used for treating bed nets. The second major vector control method is indoor residual spraying with pyrethroids or the organochloride DDT. However, resistance to pyrethroids frequently confers resistance to DDT. Therefore, alternative insecticides are urgently needed. METHODOLOGY/PRINC...

This study aims to investigate the expression of the hematopoietic pre-B-cell leukemia transcription factor-interacting protein (HPIP) and its association with platinum resistance in epithelial ovarian cancer (EOC). The protein expression of HPIP was analyzed by immunohistochemistry in 248 patients with EOC. Furthermore, we analyzed the association between HPIP expression and clinicopathologica...

background: human malaria remains a major malady in eastern iran. vector control interventions such as indoor residual spraying are used to fight with the disease. this study was undertaken to determine the lethal and residual effects of three different pyrethroid insecticides on adult mosquitoes of anopheles stephensi on different surfaces in iran, as part of a national program to monitor inse...
