SV4O-transformed hamster cells were selected for resistance to ethidium bromide (EB). Several cell lines were established, which grew in the presence of up to 250 /tg/ml EB. The EB resistance is genetically stable. The cloned resistant cells show no difference in morphology, with the exception of the mitochondrial ultrastructure, which exhibits condensed cristae formation. The tumorigenicity of...

A case is reported of narcotic coma in a female lasting 36 hours as a result of deliberate ingestion of 250 ml of halothane. Aspiration of gastric contents led to cardiac arrest which was successfully treated. Artificial ventilation was needed. Halothane hepatitis did not develop despite prolonged episodes of respiratory and circulatory failure and medication with drugs known to interfere with ...

Sudden cardiac arrest (SCA) is recognized as a serious public health problem, accounting for 250 000 to 300 000 deaths per year; it is now the third-leading cause of death behind cancer and nonsudden cardiovascular deaths.1,2 Immediate, well-performed cardiopulmonary resuscitation (CPR) and early defibrillation are the only out-of-hospital interventions that improve outcomes.3 The chain of surv...

Pharmacological and preventive properties of Petroselinum sativum seed extracts are well known, but the anticancer activity of alcoholic extracts and oil of Petroselinum sativum seeds on human breast cancer cells have not been explored so far. Therefore, the present study was designed to investigate the cytotoxic activities of these extracts against MCF-7 cells. Cells were exposed to 10 to 1000...

Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion whi...

We describe algorithms for polynomial factorization over the binary field F2, and their implementation. They allow polynomials of degree up to 250 000 to be factored in about one day of CPU time, distributing the work on two processors.

volemic events during PP, an infusion of NaCl 0.9% 500 ml should be given during PP [3, 4]. If saline infusion was given after PP the loss of red cell mass with the tubing system could be reduced from 12,0 ml to 1,3 ml per donation on average [5]. However, the disadvantage of this method is that hypovolemic events cannot be prevented during PP. On the other hand, if 500 ml NaCl 0.9% is given st...

Currently in the course we are showing that we can approximate continuous functions on compact sets with piecewise constant functions; in other words, with boxes. We will finish this today. Remaining in the representation section we still have: polynomial fit of continuous functions, functions we can fit succinctly, and GANs. Remark 1.1 (Homework comment.). A brief comment about problem 2(c); i...

La presente investigación tuvo como objetivo comparar los aditivos químicos Consolid 444 y Con-Aid para mejorar la capacidad de soporte un suelo arcilloso. Las muestras fueron extraídas del tramo carretera Pedro Ruiz–San Carlos entre km 3+000 4+000, provincia Bongará, Perú; asimismo se realizaron ensayos laboratorio determinar las propiedades físicas mecánicas estabilizado sin estabilizar. Los ...
