Abstract Univariate decision tree induction methods for multiclass classification problems such as CART, C4.5 and ID3 continue to be very popular in the context of machine learning due their major benefit being easy interpret. However, these trees only consider a single attribute per node, they often get quite large which lowers explanatory value. Oblique building algorithms, divide feature spa...

considering great medicinal value of hyssopus officinalis l. and possibility of its mass production through in vitro culture, two individual experiments was conducted. effect of various concentrations (0, 2.2, 4.4 and 11 µmol) of tdz and bap in combination with 1 µmol of iaa on direct regeneration from nodal explants were assessed. significant difference between treatments was observed (p≤ 0.01...

In trial ALL-BFM 86, the largest multicenter trial of the Berlin-Frankfurt-Münster (BFM) study group for childhood acute lymphoblastic leukemia (ALL), treatment response was used as an overriding stratification factor for the first time. In the previous trial ALL-BFM 83, the in vivo response to initial prednisone treatment was evaluated prospectively. A blast cell count of > or = 1,000/microL p...

Right bundle branch block (RBBB) and left (LBBB) are commonly seen in geriatric cases posted for surgeries. LBBB usually results from conduction system degeneration or myocardial pathology. is often associated with hypertension, myocarditis, coronary heart disease, aortic valve cardiomyopathy etc. We report a case of diagnosed preoperatively emergency spinal decompression. After induction anaes...

Drosophila tracheal terminal branches are plastic and have the capacity to sprout out projections toward oxygen-starved areas, in a process analogous to mammalian angiogenesis. This response involves the upregulation of FGF/Branchless in hypoxic tissues, which binds its receptor Breathless on tracheal cells. Here, we show that extra sprouting depends on the Hypoxia-Inducible Factor (HIF)-alpha ...

Arenaviruses are enveloped RNA viruses with a nonlytic life cycle that cause acute and persistent infections. Here, we investigated the role of the host cell's unfolded protein response (UPR) in infection of the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV). In mammalian cells, the endoplasmic reticulum (ER) chaperone protein GRP78/BiP functions as the principal sensor for the...

SUMMARY The purpose of this study was to determine the prevalence of repetitive ventricular responses caused by non-bundle-branch re-entry and bundle-branch re-entry in 47 patients with and in 50 patients without ventricular tachycardia. We also compared the prevalence of repetitive ventricular responses using two types of electrophysiological stimulation: single premature ventri-cular stimulat...

pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...
