Primula auriculata (Tootia) is one of the most important local medicinal plants in Hamedan district, Iran. To investigate cytotoxicity and apoptosis induction of crude methanolic extract and different fraction of it we compared several methods on HT-29 human colon Adenocarcinoma cells. Cancer cell proliferation was measured by 3-(4, 5‑dimethylthiazolyl)-2, 5‑diphenyl‑tetrazolium bromide (MTT) a...

    Chronic lymphocytic leukemia (CLL) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. Many Ferula species, including F. asa-foetida, synthesize terpenyloxy coumarins. One of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines.     In this study induction of apoptosis by umbellipre...

This paper presents a new strategy to improve the performances of speed control of a Double-Fed Induction Machine (DFIM), whose stator and rotor windings are connected to a voltage inverter PWM (Pulse Width Modulation) independently. This work shows the robustness of the adaptive Backstepping control strategy applied to the DFIM. The main objective of this work is to stabilize the speed of the ...

We conducted a randomized, double-blind comparison of 8% sevoflurane and propofol as induction agents for day-case cystoscopy in 102 patients. All patients received an i.v. cannula and breathed oxygen 5 litre min-1. Anaesthesia was induced with propofol i.v. or inhalation of 8% sevoflurane and 10% Intralipid (as a placebo) i.v., delivered by a blinded observer. Anaesthesia was maintained in all...

A novel, improved equivalent circuit model of double-sided linear induction motors (DLIMs) is proposed, which takes the skin effect and nonzero leakage reactance secondary, longitudinal, transverse end effects into consideration. Firstly, traditional with longitudinal are briefly reviewed. Additionally, correction coefficients for derived by one-dimensional analysis models given. Secondly, fact...

The C-Repeat Binding Factor (CBF) cold-response pathway has a prominent role in cold acclimation, the process whereby certain plants increase tolerance to freezing in response to low nonfreezing temperatures. In Arabidopsis, the CBF pathway is characterized by rapid induction of the C-Repeat Binding Factor 1 (CBF1), CBF2, and CBF3 genes, which encode transcriptional activators, followed by indu...
