Metabolism of levodopa via the enzyme catechol-O-methyltransferase requires S-adenosylmethionine (SAM) as a methyl donor. SAM caused Parkinson disease (PD)-like symptoms in rodents. Therefore, SAM could contribute to a decreased efficacy of levodopa in the long term. SAM levels were significantly reduced in levodopa-treated PD patients, but they showed increased enzyme methionine adenosyl trans...

This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...

objective: the aim of this study is to explore the confirmatory factor analysis results of the persian adaptation of statistics anxiety measure (sam), proposed by earp. method: the validity and reliability assessments of the scale were performed on 298 college students chosen randomly from tabriz university in iran. confirmatory factor analysis (cfa) was carried out to determine the factor stru...

Keratinocyte growth factor (KGF) from gastric fibroblasts have been reported to stimulate proliferation of scirrhous gastric cancer cells with K-samII amplification in a paracrine manner. The aim of this study was to evaluate the clinical significance of the co-expression of K-sam and KGF in gastric carcinomas. A total of 136 primary gastric tumors were investigated by staining with antibodies ...

The mitochondrial outer membrane contains two translocase machineries for precursor proteins--the translocase of the outer membrane (TOM complex) and the sorting and assembly machinery (SAM complex). The TOM complex functions as the main mitochondrial entry gate for nuclear-encoded proteins, whereas the SAM complex was identified according to its function in the biogenesis of beta-barrel protei...
