The cellular mechanisms that regulate the topographic arrangement of myelin internodes along axons remain largely uncharacterized. Recent clonal analysis of oligodendrocyte morphologies in the mouse optic nerve revealed that adjacent oligodendrocytes frequently formed adjacent internodes on one or more axons in common, whereas oligodendrocytes in the optic nerve were never observed to myelinate...

some growth parameters of pea (cv. pleven 4) and vetch (cv. obrazets 666) after treatment with organic fertilizer were studied in a field trial carried out at the institute of forage crops, pleven, bulgaria. humustim as organic fertilizer was applied through presowing treatment of seeds, treatment during vegetation and combination between both, at different doses. ratios of aboveground weight t...

Submergence induces rapid elongation of rice coleoptiles (Oryza sativa L.) and of deepwater rice internodes. This adaptive feature helps rice to grow out of the water and to survive flooding. Earlier, we found that the growth response of submerged deepwater rice plants is mediated by ethylene and gibberellin (GA). Ethylene promotes growth, at least in part, by increasing the responsiveness of t...

In the course of field and laboratory research, selection samples spring hexaploid triticale were studied for their selection-valuable traits lodging resistance. The correlation analysis revealed a between individual that determine tolerance. most stable relationship resistance is with length second third internodes breaking strength straw. An additional criterion sum lengths 2nd 3rd internodes...

The pattern of remyelination after traumatic spinal cord injury remains elusive, with animal and human studies reporting partial to complete demyelination followed by incomplete remyelination. In the present study, we found that spared rubrospinal tract (RST) axons of passage traced with actively transported dextrans and examined caudally to the lesion 12 weeks after mouse spinal cord contusion...

In Australia, Fusarium pseudograminearum and F. culmorum are the two main fungi causing crown rot, while Bipolaris sorokiniana is causal agent of common root rot. graminearum typically linked with head blight; however, it has been associated rot in Australia other parts world. This study investigated reactions single cultivars barley, bread wheat, durum oat, triticale to inoculation strains pse...

BACKGROUND AND AIMS Fitting the parameters of models of plant organ growth is a means to investigate how environmental conditions affect plant architecture. The aim of this article is to evaluate some non-linear methods for fitting the parameters of multi-phase models of the kinetics of extension of plant organs such as laminae, sheaths and internodes. * METHODS A set of computational procedu...

OBJECTIVES Being overweight or obese is a key risk factor for the onset and exacerbation of knee pain. Policy and clinical guidelines encourage lifestyle changes as part of prevention or supported self-management. The present study explores how people who have not consulted for knee pain understand weight in relation to joint pain, if and how they self-manage and potential barriers to doing so....
