Random search trees have the property that their depth depends on the order in which they are built. They have to be balanced in order to obtain a more eecient storage-and-retrieval data structure. Balancing a search tree is time consuming. This explains the popularity of data structures which approximate a balanced tree but have lower amortised balancing costs, such as AVL trees, Fibonacci tre...

The roots and rhizomes of Valeriana (Valerianaofficinalis L.) are rich with valuable metabolites such as valerenic acid and valepotriates are used as mild sedatives. The aim of the present study was to investigatethe effect of four levels of calcium and potassium compounds (half, full, 2 and 4-fold) of normal Murashige and Skoog (MS) media including KI and CaCl2on ValerianaofficinalisL. hairy r...

We contrasted the physiology and peripheral targets of subclassified nociceptive and nonnociceptive afferents that express acid-sensing ion channel (ASIC)-like currents. The threshold for current activation was similar in eight distinct cell subclasses regardless of functional modality (pH 6.8). When potency was determined from concentration-response curves, nonnociceptors exhibited currents wi...

Nociceptive cells of the dorsal root ganglion (DRG) were subclassified, in vitro, according to patterns of voltage-activated currents. The distribution and form of nicotinic ACh receptors (nAChRs) were determined. nAChRs were present on both capsaicin-sensitive and -insensitive nociceptors but were not universally present in unmyelinated nociceptors. In contrast, all A delta nociceptors (types ...

Treatment of hairy cell leukemia with 2-chlorodeoxyadenosine (2-CdA) induces complete remissions in 85% of patients. Complete remission has been defined as the absence of hairy cells in the bone marrow after routine morphologic examination. To determine if hairy cells could be detected in complete remission bone marrows using immunohistochemical techniques with antibodies L26 (CD20) and DBA.44,...

We contrasted the physiology and peripheral targets of subclassified nociceptive and non-nociceptive afferents that express ASIC-like currents. The threshold for current activation was similar in 8 distinct cell subclasses regardless of functional modality (pH 6.8). When potency was determined from concentration response curves, non-nociceptors exhibited currents with significantly greater pote...

background & aim:oxidative stresses caused by free radicals are known to promote many diseases such as inflammation and cancer; therefore, any plant product that can inhibit free radical production can play an important role in preventing diseases. we aimed to compare the fracture rate and the scavenging activity of free radicals, and the antioxidant composition of rolb-transformed hairy root o...

in order to study the density and diversity of weeds and yield of barley and hairy vetch affected by mixed intercropping ratios, a field experiment was performed based on a randomized complete block design with four replications at the agricultural research station, college of agriculture, ferdowsi university of mashhad during growing season of 2012-2013. ratios of mixed intercropping were 75% ...

Agrobacterium rhizogenes-mediated 'hairy root' cultures were established in Atropa acuminata. The chemical profiling of the hairy roots was carried out by a new mass spectrometric technique, direct analysis in real time (DART). The intact hairy roots were directly analyzed by holding them in the gap between the DART ion source and mass spectrometer. Two alkaloids, atropine and scopolamine, were...

Momordica charantia (Cucurbitaceae) is an important vegetable and also medicinal crop which produces the bioactive compounds for various biological activities with potential uses in human health. The present investigation relates to elicitors of jasmonic acid (JA) and salicylic acid (SA) to enhance biomass accumulation and phenolic compound production in hairy root cultures of M. charantia. Hai...
