BACKGROUND The pair-rule gene, hairy, encodes a basic helix-loop-helix transcription factor and is required for patterning of the early Drosophila embryo and for morphogenesis of the embryonic salivary gland. Although hairy was shown to be expressed in the tracheal primordia and in surrounding mesoderm, whether hairy plays a role in tracheal development is not known. PRINCIPAL FINDINGS Here, ...

Inflammatory endobronchial polyp is a rare disease mostly encountered in asthmatic patients. Chronic airway and foreign material irritation or thermal injury may result in the formation of granulated tissues and become polypoid mass. Herein, we describe a 52-year-old man with severe respiratory distress and infection with 35 years history of smoking. He had an obstructive pattern in his pulmona...

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...

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,...

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...

the gastric inflammatory fibroid polyp (ifp) is a rare benign tumor of unknown etiology that is localized mainly in the antrum and presents endoscopically as submucosal mass. the lesion manifests as abdominal pain, weight loss, bleeding, dyspeptic symptoms, and iron deficiency anemia. we report a case of gastric ifp presented with microcytic anaemia, dyspepsia, malena and weight loss. endoscopy...
