Many organs including the mammalian lung and vascular system consist of branched tubular networks that transport essential gases or fluids, but the genetic programs that control the development of these complex three-dimensional structures are not well understood. The Drosophila melanogaster tracheal (respiratory) system is a network of interconnected epithelial tubes that transports oxygen and...

Background: Palliative care has become increasingly important in the last decades with a rise needy patients and subsequent shortage of health professionals serving palliative care, making it global public concern. Patients methods: Educational interventional study conducted Department Anaesthesiology tertiary teaching institute. Pre- post-tests by standardized validated multiple choice questio...

The present article is aimed at study on agroclimatic conditions of cultivation of sunflower throughout selected substations at Kurdistan  Province by means of GIS system. In this investigation, meteorological data have been received from synoptic stations based on daily, monthly, and annually trend from Iran Meteorological Organization (IMO) at Kurdistan  Province and then homogeneity of data ...

Matrix isolation IR spectroscopy has been used to study the vacuum pyrolysis of hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4) and decamethyl cyclopentasiloxane (D5), and the results interpreted in the context of various kinetic models. In particular, it is shown that the significant pyrolysis products--which include CH3, CH4, C2H2, C2H4, C2H6 and SiO--may be satisfactorily ...

Vegetative propagation of Persian walnut (Juglans regia L.) is more difficult than many other fruit trees. Temperature, relative humidity, water status the scion and rootstock, nutrient uptake, time grafting, physiological condition type all can affect grafting success. An experiment was conducted to evaluate effects post-budding irrigation frequency (3, 7 10-days), budding date (14 June, 5 26 ...

= Abstract =A human embryo obtained from a salpinx removed for the treatment of tubal gestation was serially sectioned and observed. On gross examination, the embryo showed three prominent pharyngeal arches, but not the cervical sinus. The upper arm bud had just begun to appear with a slight elevation in the skin ectoderm. Both the anterior and posterior neuropores had already been closed. The ...

CONTEXT Age at menarche (AAM) is an important trait both biologically and socially, a clearly defined event in female pubertal development, and has been associated with many clinically significant phenotypes. OBJECTIVE The objective of the study was to identify genetic loci influencing variation in AAM in large population-based samples from three countries. DESIGN/PARTICIPANTS Recalled AAM ...

BACKGROUND The microRNA-200 (miR-200) family acts as a major suppressor of epithelial-mesenchymal transition (EMT). Impaired miR-200 expression may lead to EMT initiation and eventually cancer dissemination. The presence of tumor budding cells (TBC) is associated with metastasis and poor prognosis, and molecular similarities to EMT indicate that these cells may reflect ongoing EMT. The aim of t...

In Brassica napus, floral development is a decisive factor in silique formation, and it is influenced by many cultivation practices including planting date. However, the effect of planting date on floral initiation in canola is poorly understood at present. A field experiment was conducted using a split plot design, in which three planting dates (early, 15 September, middle, 1 October, and late...

The formation of Marx's national concept has roughly gone through three different stages development, namely the initial exploration stage concept, or budding period. This historical period focuses on basic viewpoints nationality and related issues in classic works. theoretical establishment view nation, focusing analysis more mature theory than infancy basis analyzing reality social revolution...
