shoulder movements are a complex motor act, controlled by many muscles attached to thescapula and the vertebral column. these muscles are innervating by motoneurons (mns) located in theventral horn of the spinal cord. motoneurons of the ventral horn are arranged such that several groups ofmns can be distinguished in a transverse section through the spinal cord. the anatomical or functionalimpli...

the aim of this critical appraisal and hazards of surface electromyography (semg) is to enhance the data acquisition quality in voluntary but complex movements, sport and exercise in particular. the methodological and technical registration strategies deal with telemetry and online data acquisition, the placement of the detection electrodes and the choice of the most adequate normalization mode...

Background: Involvement of Wnt proteins and one of its antagonist known as secreted Frizzled Related Protein type-4 (sFPRP-4) was reported in rodent ovarian follicular development. Other studies showed an ap- Abstracts of the 11th Royan International Congress on Reproductive Biomedicine 7 7 International Journal of Fertility & Sterility (IJFS), Vol 4, Suppl 1, Summer 2010 optotic-associated exp...

Ligand regulated localization controllable protein constructs were optimized in this study. Several constructs were made from a classical nuclear export signal (HIV-rev, MAPKK, or progesterone receptor) in combination with a SV40 T-antigen type nuclear import signal. Different ligand binding domains (LBDs from glucocorticoid receptor or progesterone receptor) were also tested for their ability ...

BACKGROUND Cytoplasmic mRNA localization is a widespread mechanism for restricting the translation of specific mRNAs to distinct regions of eucaryotic cells. This process involves specific interactions between cellular factors and localization signals in the 3' untranslated regions of the localized mRNA. Because only a few of these cellular factors have been identified, it is not known whether ...

Duck enteritis virus (DEV) multifunctional tegument protein UL13 is predicted to be a conserved herpesvirus kinase; however, little known about its subcellular localization signal. In this study, through transfection of 2 nuclear signals DEV fused enhanced green fluorescent protein, bipartite (NLS) were identified. We found that ivermectin blocked the NLS-mediated import UL13, showing signal cl...

transforming growth factor betas (tgf?s) are one of the most widespread and versatile cytokines. the three mammalian tgf? isoforms, ?1, ?2, and ?3, and their receptors regulate proliferation of neuronal precursors as well as survival and differentiation in neurons of developing and adult nervous system. functions of tgf?s has a wide spectrum ranging from regulating cell proliferation and differ...

source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

ASH1 mRNA localizes at the bud tip of late-anaphase yeast, resulting in accumulation of Ash1p in the daughter nucleus. We show that disruption of the secondary structure, but not the protein coding, of all four ASH1 localization elements resulted in RNA and protein delocalization. Localization of both was incrementally restored by replacement of each of the four elements. However, transposition...

Bacterial proteins are typically sorted to subcellular regions with distinct physical characteristics that serve as cellular 'addresses', but many proteins are evidently sorted to specific areas that lack any apparent unique identity. Recent work in Bacillus subtilis suggests that such proteins may be localized by interacting with extracellular domains of proteins in an adjacent cellular compar...
