An antibody raised against a peptide based on the C-terminal derived amino acid sequence from a cloned Drosophila melanogaster (fruit fly) gene, Rdl (resistant to dieldrin), was used to investigate localization of a GABA receptor subunit in adult male D. melanogaster. Many regions in the brain and thoracic ganglia were stained with this antibody. For(More)
In eukaryotes, mitogen-activated protein kinases (MAPKs) are part of signaling modules that transmit diverse stimuli, such as mitogens, developmental cues, or various stresses. Here, we report a novel alfalfa MAPK, Medicago MAP kinase 3 (MMK3). Using an MMK3-specific antibody, we detected the MMK3 protein and its associated activity only in dividing cells.(More)
BACKGROUND The mechanisms by which the abdominal muscles move and control the lumbosacral spine are not clearly understood. Descriptions of abdominal morphology are also conflicting and the regional anatomy of these muscles has not been comprehensively examined. The aim of this study was to investigate the morphology of regions of transversus abdominis and(More)
Estrogen formation in the brain catalysed by the cytochrome P450arom is required for the control of estrogen-dependent neural mechanisms regulating reproductive behaviour. A polyclonal antibody was raised against a 15-amino acid fragment of the chicken ovarian P450arom protein, to localise aromatase-immunoreactive (AR-IR) cells in the adult female chicken(More)
A three-round Delphi study was conducted to gather data on ethical reasoning among psychiatric nurses (N = 26 in round one (R1), decreasing to N = 14 in the final round (R3)). Transcripts of questionnaires were carefully read and compared. Responses were manually sorted into categories, themes and patterns of interest. Eight debates emerged from the data.(More)
Biomechanical models predict that recruitment of gluteus maximus (GMax) will exert a compressive force across the sacroiliac joint (SIJ), yet this muscle requires morphologic assessment. The aims of this study were to document GMax's proximal attachments and assess their capacity to generate forces including compressive force at the SIJ. In 11 embalmed(More)
Localization in the nervous system of Drosophila melanogaster of a cloned Drosophila muscarinic acetylcholine receptor (mAChR) was investigated using a polyclonal antiserum raised against a peptide corresponding to the predicted receptor carboxyl terminal domain. Immunocytochemical studies on fly sections indicated that the product of the Dm1 mAChR gene was(More)
The objectives of this study were to investigate the anatomical relationship between the proximal adductor longus (AL) and rectus abdominis muscles and to determine whether unilateral loading of AL results in strain transmission across the anterior pubic symphysis to the contralateral distal rectus sheath. Bilateral dissections were conducted on 10 embalmed(More)
