cotton is of particular importance  in fiber crops. variation in the cultivars and the potential of different cultivars is an important step in increasing production per unit area. in this study, nine new varieties of cotton including cotton hybrids successful and successful genotypes in a randomized complete block design with four replications,  with varamin camecial cultivar were evaluated in...

Although some sensory ganglion cells in mature animals are catecholaminergic, most mammalian sensory neurons that express the catecholamine-synthesizing enzyme tyrosine hydroxylase (TH) do so only transiently during early gangliogenesis in vivo. The lack of TH expression at later stages appears to be due to modulation of this catecholaminergic potential. A previous study showed that the phenoty...

Sensory and neurosecretory innervation of each leech excretory complex, a nephridium and its bladder, is accomplished by a single neurone, the nephridial nerve cell (NNC). The NNC monitors the extracellular Cl- concentration, which ranges between 20 and 100 mmol l-1 depending on the physiological state. The NNC contains FMRFamide in its soma and sensory terminals in the nephridium. Bath or foca...

The development of the axial skeleton is a complex process, consisting of segmentation and differentiation of somites and ossification of the vertebrae. The autosomal recessive skeletal fusion with sterility (sks) mutation of the mouse causes skeletal malformations due to fusion of the vertebrae and ribs, but the underlying defects of vertebral formation during embryonic development have not ye...

[1] Between 105–115 degrees, the SKS waveform is complicated by the formation of SPdKS, a wave that has segments of P diffraction along the core mantle boundary. While previous studies have primarily focused on the moveout of SPdKS from SKS, we analyze the concomitant reduction of the SKS amplitude. Long-period SKKS/SKS amplitude ratios present a coherent global pattern. SKKS/ SKS is relatively...

BACKGROUND Seborrheic keratoses (SKs) are common skin lesions that have been shown to occur with increasing age, although the age of onset is not well recorded. OBJECTIVE To determine the prevalence, nature, and distribution of SKs in young people. METHODS One hundred seventy people aged 15 to 30 years were given a total body examination during which the presence, number, site, and size of ...

BACKGROUND Coma's are a major cause of clinical deterioration or death. Identification of risks that predispose to coma are important in managing patients; however, the risk factors for nosocomial nontraumatic coma (NNC) are not well known. Our aim was to investigate the risk factors in patients with NNC. METHODS A retrospective case-control design was used to compare patients with NNC and a ...
