We have studied the role of the temporal correlation of multiple cell discharges in the facilitation of the somatosensory information transmission from the gracilis nucleus to the primary somatosensory (SI) cortex in anesthetized rats. Pairs of gracilis neurons or gracilis-SI cortical neurons were recorded during application of 20-ms tactile stimuli in control conditions and after electrical co...

Prevention of nerve injury-induced tactile, but not thermal, hypersensitivity is achieved by ipsilateral lesions of the dorsal columns or lidocaine microinjection into the nucleus gracilis (n. gracilis). These and other data support the possibility that tactile hyperresponsiveness after nerve injury may be selectively mediated by a low-threshold myelinated fiber pathway to the n. gracilis. Here...

Pugettia gracilis and Oregonia gracilis are among the most abundant crab species in Alaskan kelp beds and were surveyed in two different kelp habitats in Kachemak Bay, Alaska, U.S.A., from June 2005 to September 2006, in order to better understand their temporal distribution. Habitats included kelp beds with understory species only and kelp beds with both understory and canopy species, which we...

112 specimens of capoeta capoeta gracilis from the shrioud river were examined. the prevalence and abundance of parasites were significantly higher in the area between the mouth to behind the opercle. susceptibility of infection was not significantly different between male and female fish. the prevalence of infection was the lowest in the largest length group. histopathological study revealed b...

The harpacticoid copepod Macrosetella gracilis uses colonies of the nitrogen-fixing cyanobacterium Trichodesmium spp. as a floating substrate and nursery. This association enables the copepod to lead a pelagic existence. Molecular and morphological data both indicate that M. gracilis is maintained as a single, circumglobal species across the tropical and subtropical Atlantic and Pacific. Mitoch...

A rapid three-step procedure utilizing heat treatment, ammonium sulfate fractionation, and affinity chromatography on Matrex gel Orange A purified fumarase (EC 4.2.1.2) 632-fold with an 18% yield from crude extracts of Euglena gracilis var. bacillaris. The apparent molecular weight of the native enzyme was 120,000 as determined by gel filtration on Sephacryl S-300. The preparation was over 95% ...

A new medium selective for Bacteroides gracilis was developed. The medium is tryptic soy agar (Difco Laboratories, Detroit, Mich.) containing nalidixic acid, teicoplanin, sodium formate, sodium fumarate, and potassium nitrate. All 18 strains of B. gracilis tested grew with only minimal inhibition. Most of the other 214 organisms tested, including most Bacteroides species, other anaerobes, and a...

The effects of sex, injuries, season and site on the growth of the spiny lobsters Panulirus gracilis, and P. inflatus, were studied through mark-recapture techniques in two sites with different ecological characteristics on the coast of Guerrero, México. Panulirus gracilis occurred in both sites, whereas P. inflatus occurred only in one site. All recaptured individuals were adults. Both species...

The chloroplast genome of Eutreptia viridis Perty, a basal taxon in the photosynthetic euglenoid lineage, was sequenced and compared with that of Euglena gracilis Ehrenberg, a crown species. Several common gene clusters were identified and gene order, conservation, and sequence similarity was assessed through comparisons with Euglena gracilis. Significant gene rearrangements were present betwee...

OBJECTIVE The gracilis was once applied in reconstructing erectile function but its appearance was bulky. We aimed to design a model meeting the requirements of both reducing volume and retaining function. MATERIALS AND METHODS The gracilis muscles of 6 rabbits were harvested, applied colorful vascular perfusion and modified Sihler's intramuscular nerve staining. According to their intramuscu...
