introduction: we did this study because there were a few studies about aorto-branch junction. methods: four light microscope and electron microscope study, the abdominal aorta, renal artery, and the adjoining right and left renal arteries were dissected out from 4 neonate dogs. results: based on the results, there is only one cell type in the tunica intima of endothelium in both arteries. in ab...

objective(s): thyroid hormones play an essential role in fetal growth and maternal hypo-thyroidism which leads to cardiovascular deficiency in their offspring.  considering this, we intended to investigate the impact of gestational hypothyroidism on offspring vascular contractibility and possible underlying mechanisms. materials and methods: hypothyroidism was induced in female rats by administ...

saffron, crocus sativus l. (c. sativus) is rich in carotenoids and used in traditional medicine for treatment of various conditions such as coughs, stomach disorders, amenorrhea, asthma and cardiovascular disorders. these therapeutic effects of the plant are suggested to be due to its relaxant effect on smooth muscles. the effect of c. sativus and its constituents on different smooth muscles an...

An antiviral protein (25 kD) isolated from leaves of Celosia cristata (CCP 25) was tested for depurination study on ribosomal RNA from yeast. Ribosomal RNA yielded 360 nucleotide base fragment after treatment with CCP 25 indicating that CCP 25 was a ribosome inactivating protein. CCP 25 also inhibited translation of brome mosaic virus (BMV) and pokeweed mosaic virus (PMV) RNAs in rabbit reticul...

2014 A stopped-flow apparatus and control system, designed for the study of rapid reaction kinetics in solution by X-ray scattering, is described. Inspired from a commercial stopped-flow unit used with UV and visible light, the X-ray device has a dead-time of 80 ms. Results are presented for the polymerization of the coat protein of Brome mosaic virus following a pH jump, using a small angle X-...

‎in this paper‎, ‎we introduce the structure of a groupoid associated to a vector field‎ ‎on a smooth manifold‎. ‎we show that in the case of the $1$-dimensional manifolds‎, ‎our‎ ‎groupoid has a‎ ‎smooth structure such that makes it into a lie groupoid‎. ‎using this approach‎, ‎we associated to‎ ‎every vector field an equivalence‎ ‎relation on the lie algebra of all vector fields on the smooth...

The structural phenotype of the movement proteins (MPs) of two representatives of the Bromoviridae, alfalfa mosaic virus (AMV) and brome mosaic virus (BMV), was studied in protoplasts. Immunofluorescence microscopy showed that the MPs of these viruses, for which there has been no evidence of a tubule-guided mechanism, assemble into long tubular structures at the surface of the infected protopla...

We have engineered an optical nanoconstruct composed of genome-depleted brome mosaic virus doped with indocyanine green (ICG), an FDA-approved near-infrared (NIR) chromophore. Constructs are highly monodispersed with standard deviation of ±3.8 nm from a mean diameter of 24.3 nm. They are physically stable and exhibit a high degree of optical stability at physiological temperature (37 °C). Using...

The development of the nematode Spinitectus inermis (Zeder, 1800), a parasite of the stomach of eels, Anguilla anguilla (L.) in Europe, was experimentally studied. Mayfly nymphs Caenis macrura, Ecdyonurus dispar, Heptagenia sulphurea, Potamanthus luteus and Seratella ignita from Portugal and the Czech Republic were found to serve as experimental intermediate hosts. After ingestion of the nemato...

The present study is the continuation of a program aimed at investigation of antimicrobial and photochemical properties of Lawsonia inermis leaf extract to justify the traditional claim endowed upon this herbal drug as a rasayana in Ayurveda. The antimicrobial activity was evaluated according to the disk diffusion method by using Gram positive; B. subtilius, S. aureus and S. epidermidis and Gra...
