Giant red sea cucumbers, Parastichopus californicus, are commercially harvested in the U.S. Pacific Northwest; however, the nutritional and chemical properties of its edible muscle bands and body wall have not been fully elucidated. In particular are the fatty acid profiles of P. californicus tissues, which have not been documented. Sea cucumbers were delivered live and muscle bands and body wa...

Dysfunctions of MeCP2 protein lead to various neurological disorders such as Rett syndrome and Autism. The exact functions of MeCP2 protein is still far from clear. At a molecular level, there exist contradictory data. MeCP2 protein is considered a single immunoreactive band around 75 kDa by western-blot analysis but several reports have revealed the existence of multiple MeCP2 immunoreactive b...

A bacterium was isolated from the soil of dumping ground for cattle yard waste by enrichment culture containing aflatoxin B1. This bacterium was closely related to Bacillus firmus that was found to be a non-pathogenic bacterium. The minimum inhibitory concentration of aflatoxin B1 to the bacterium was found to be 80 microg ml(-1) as measured by total viable count and soluble protein content met...

Rat pheochromocytoma (PC12) cells express two distinct nerve growth factor receptors (NGFRs), p75NGFR and trkA (p140trk). In addition to these receptors, by using 125I-mNGF affinity labeling and BS3 chemical cross-linking of PC12 cell protein, we have identified two additional trkA protein bands with apparent molecular weights of 220,000 and 300,000. These bands contain trkA, but were not immun...

In discussing the principles of quantitative analysis in thin-layer media, we show that requirements for quantitative analysis are not satisfied when stained protein electrophoretic bands are scanned with a conventional rectangular-slit densitometer. We investigated a high-resolution densitometer based on a linear photodiode array as an alternative analytical tool, using stained electrophoretic...

Background: Male infertility has many causes, including genetic infertility. The NOP2/Sun domain family, member7 (Nsun7) gene, which encodes putative methyltransferase Nsun7, has a role in sperm motility. The aim of the present study was to investigate the effect of the T26248G polymorphism on Nsun7 protein function and its role in male infertility. Materials and Methods: Semen samples were col...

human fascioliasis due to unknown species and animal fascioliasis caused by both or one of fasciola spp. are commonly seen in iran. to compare electrophoretic patterns of somatic and excretory-secretory antigens of f. hepatica and f. gigantica  by sodium dodecyl sulphate polyacrylamide gel electrophoresis (sds-page), the adult flukes were collected from infected slaughtered bovine livers. e/s a...

the taxonomic affinity of six species of crocus (c, cancellatus subsp. damascenus c. almehensis, c. gilanicus, c. sativus, c.pallassi subsp. haussknechtii,c. speciosus subsp. speciosus) from iran were studied usingdifferent electrophoresis techniques. the similarity index of the species was computed by comparison of protein bands of - corm and seed tissues, and the related dendrogms of affinity...
