avulsion is one of the most serious emergencies in dental office. in the event of any problem, the tooth should be stored in a medium that supports the periodontal ligament cell viability. in other clinical situations, preserving media, growth factors and mitogenic products may be useful in repairing the traumatized tissues. it has been previously reported that levodopa (l-dopa) accelerates hea...

we conducted this study to determine the level of immunity after vaccination of lambs with whole bodyechinococcus granulosus. to do so, 200 mature e. granulosus parasites, which were kept in 10% formalinefor 8 months, were obtained from the department of parasitology, school of veterinary medicine, ferdowsiuniversity of mashhad. the soluble protein of the parasite was prepared. the sample was h...

evaluation of gastric emptying rate using nuclear scintigraphy as the gold standard method has been studied in various animals, but there is no report in suckling lambs. the aim of this study was to develop a nuclear scintigraphic method to visualize and measure abomasal emptying rate by estimation of scintigraphic half emptying time (t1/2) in the live neonatal lamb. five healthy, female irania...

the objectives of this study were to determine the effects of feeding rapeseed (27%, dm basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (fa), profile (ratios and indices),enzyme activitiesfrom thecarcassin lambs fed cereal-based diets. simultaneously, itwas examined the relationship between ingested fa and carcass fa. samples were obtaine dfrommal efa...

Estriol accounts for an average of 74% of the principal Kober-positive steroids in the urine of 13 women during uncomplicated pregnancies. This proportion is independent of the stage of pregnancy, from 20 weeks until term. The average ratio of estriol to ring-D a#{149}ketols (mainly 16ahydroxyestrone and 16-ketoestradiol-17) is about 5:1 over the same period. In 17 pregnant women with diabetes,...

In the past fifteen years, the United States Supreme Court has decided three cases in which it tentatively began to explore what the United States Constitution has to say about issues that are popularly described as the "right to die." In this article, I suggest that the current state of constitutional analysis does not provide for an effective mechanism for securing an individual's "right to d...

Lamb and mutton are the most important sources of income for South African Merino farmers. The possibility of genetically improving survival of a Merino lambs was assessed with data from 5769 lambs that were born alive in the Cradock fine wool stud from 1998 to 2003. Three traits can possibly be linked to lamb survival and can therefore be included in selection programs, namely birth coat score...

Lamb waves are dispersive in a plate and elastic properties of anisotropic materials are dependent on the crystal orientation. It is expected that the wave propagation on a thin anisotropic plate is complex due to dispersion of Lamb waves which will be dependent on the propagation direction. Therefore it is essential to understand elastic waves in an anisotropic plate. In the present work, a si...

The folding mechanisms for β-barrel membrane proteins present unique challenges because acquisition of both secondary and tertiary structure is coupled with insertion into the bilayer. For the porins in Escherichia coli outer membrane, the assembly pathway also includes association into homotrimers. We study the folding pathway for purified LamB protein in detergent and observe extreme hysteres...

In this article, ultrasonic guided wave propagation and interaction with the rivet hole cracks has been formulated using closed-form analytical solution while the local damage interaction, scattering, and mode conversion have been obtained from finite element analysis. The rivet hole cracks (damage) in the plate structure gives rise to the non-axisymmetric scattering of Lamb wave, as well as sh...
