subsequent to phytochemical investigation on scutellaria lateriflora (labiatae) from mazandaran provincein iran, the wax ester fraction of the leaves has been investigated. using tlc, cc glc and glc-ms, the alkyl esters of the epicuticular wax was analysed. total concentration of the esters was 35% and it was shown to be composed of a homologous series having various chain lengths in the range ...
Insulin is a major target of the autoimmune response associated with destruction of pancreatic beta cells in type 1 diabetes. A peptide that spans the junction of the insulin B chain and the connecting (C) peptide in proinsulin has been reported to stimulate T cells from humans at risk for type 1 diabetes and autoimmune diabetes-prone NOD mice. Here we show that proinsulin B24-C36 peptide binds...
Hepatitis C virus (HCV) and HCV core protein are hypothesized to induce hepatic oxidative stress and exacerbate injury caused by other toxins such as ethanol that induce the cytochrome P450 enzyme, CYP2E1. In the current study, the effects of HCV core protein [sequence genotype 1b, (nt 342-915)] on parameters indicative of oxidative stress were evaluated in HepG2 cells stably over expressing CY...
The envelope glycoprotein (Env) of human immunodeficiency virus type I (HIV-1) mediates membrane fusion. To analyze the mechanism of HIV-1 Env-mediated membrane fusion, it is desirable to determine the expression level of Env on the cell surface. However, the quantification of Env by immunological staining is often hampered by the diversity of HIV-1 Env and limited availability of universal ant...
Do rural households in developing countries make market participation and volume decisions simultaneously or sequentially? This article develops a two-stage econometric model that allows testing between these two competing hypotheses regarding household-level market behavior. The first stage models the household’s choice of whether to be a net buyer, autarkic, or a net seller in the market. The...
BACKGROUND Although spinal cord injuries are frequent causes of myelopathy in young patients, stab wounds of the spinal cord rarely occur and are typically maximal symptomatic immediately after the trauma. CASE DESCRIPTION A 31-year-old male developed delayed onset of symptoms 4 years after a stab wound to the cervical spinal cord attributed to a plant needle (plant called Mandacaru). Followi...
