Small conductive polymer force sensors were attached to the distal phalangeal pads for measuring individual finger forces exerted during submaximal static pinch. A linear force summing strain gauge dynamometer for measuring resultant five-finger pinch force was grasped vertically using a neutral wrist posture. Individual finger forces were measured at fixed(More)
Matrix-attachment regions (MARs) may function as domain boundaries and partition chromosomes into independently regulated units. In this study, BP-MAR, a 1.3-kb upstream fragment of the 5′MAR flanking the chicken lysozyme locus, was tested for its effects on integration and expression of transgenes in transgenic rice plants. Using the Agrobacterium-mediated(More)
Using light microscopy and immunocytochemistry, we investigated the morphological changes of retinal tissues and the reaction of Müller cells in the ischemic rat retina induced by increasing intraocular pressure. At early stages (from 1 h to 24 h after reperfusion), cells in the ganglion cell layer and in the inner nuclear layer showed some degenerative(More)
This study used a computer-controlled electric right angle nutrunner to investigate the relative effects of different power hand tool and process parameters on operator muscular exertions, handle stability and subjective ratings of perceived exertion. Target torque (25, 40 and 55 Nm), torque build-up time (35, 150, 300, 500 and 900 ms), and workstation(More)
 Platelet-derived growth factor (PDGF) has a targeted activity on mesenchymal cells, but the in vivo effects of PDGF are not well understood. We have applied about 3 μg of PDGF-A and PDGF-B on the differentiated chorioallantoic membrane (CAM) of 13-day-old chick embryos. After 1–3 days, specimens were evaluated macroscopically, histologically with semi- and(More)
In rabbit and rat retinae, wholemounted preparations and 40 μm thick vibratome sections were processed for nitric oxide synthase (NOS) immunoreactivity and consecutive semithin sections were immunostained with anti-NOS and anti-GABA antisera, respectively. Two types of NOS-labelled amacrine cells were identified: type 1 cells with larger somata were(More)
Finger and palmar forces were measured during actual pneumatic nutrunner operation using a strain gauge dynamometer. Eighteen student subjects were assigned to one of three categories based on hand length. Two triggers and four handle spans were presented randomly. Handle span affected maximal and submaximal grip force. As span increased from 4 cm to 7 cm,(More)
The localization of nitric oxide synthase (NOS) was investigated in the developing rat retina by immunocytochemistry and western blot analysis, using an antiserum directed against neuronal NOS. NOS-labeled cells were first detected at postnatal day 5 (P5) in the inner row of the neuroblastic layer. These cells were considered to correspond to the type 1(More)
The synaptic connectivity between rod bipolar cells and GABAergic neurons in the inner plexiform layer (IPL) of the rat retina was studied using two immunocytochemical markers. Rod bipolar cells were stained with an antibody specific for protein kinase C (PKC, α isoenzyme), and GABAergic neurons were stained with an antiserum specific for glutamic-acid(More)
Immunocytochemical methods with an antiserum against neuronal nitric oxide synthase (NOS) were applied to identify the morphology and synaptic connectivity of NOS-like immunoreactive neurons in the guinea pig retina. In the present study, two types of amacrine cells were labeled with anti-NOS antisera. Type 1 cells had large somata located in the inner(More)
