Introduction There is a need for a reliable, noninvasive biomarker for Alzheimer's disease (AD). We assessed whether short-latency afferent inhibition (SAI), a transcranial magnetic stimulation paradigm that assesses cholinergic circuits of the brain, could become such a biomarker. Methods Nineteen patients with AD underwent four SAI testing sessions. The timing of their usual donepezil dose ...

to evaluate the effects of seed priming with salicylic acid on quality and baking traits of wheat flour, cv. alvand, under different sowing dates, a factorial experiment was conducted on the basis of complete randomized block design. the factors were seed priming with salicylic acid (including untreated seeds or control treatment, 400, 800, 1200, 1600, 2000 and 2400 µm concentrations of salicyl...

Monkey cutaneous SAI and RA responses to raised and depressed scanned patterns: effects of width, height, orientation, and a raised surround. J. Neurophysiol. 78: 2503-2517, 1997. The aim of this study was to examine the slowly adapting type I (SAI) and rapidly adapting (RA) primary afferent representation of raised and depressed surface features. Isolated, raised, and depressed squares and sma...

OBJECTIVE To consider the extent, nature, and range of risk arrangements between physician groups and health maintenance organizations (HMOs) for self-administered injectable (SAI) drugs; to examine types and frequencies of SAI drug-use management strategies adopted by physician groups; and to explore the relationship between locus and level of financial risk for SAIs and physician group strate...

In the current study, self-assessed intelligence (SAI) is presented as a multidimensional construct related both to personality and to psychometric intelligence. On the basis of data obtained from a Russian student sample (N = 496), the authors validate a structural model in which SAI acts as a mediating variable between latent variables of measured IQ and the trait of acceptance of uncertainty...

BACKGROUND Investing in financial markets is promoted and protected by the government as an essential economic activity, but can turn into a gambling addiction problem. Until now, few scales have widely been used to identify gambling addicts in financial markets. This study aimed to develop a self-rating scale to distinguish them. In addition, the reliability and validity of the stock addiction...

time of acquisition desiccation tolerance in peanut seed during different growing stages was determined by evaluating seed moisture content, germination capability and electrical conductivity. it was done in research field of gorgan university of agricultural sciences and natural resources in completely block randomize design in four planting date and four replications. sampling was done weakly...

Soluble sugar composition of developing soybean seed (Glycine max L. Merr.) vary with cultivar. This study was conducted to determine the relation between soluble sugar accumulation and associated enzyme activities in developing seed of two soybean cultivars, Williams 82 and Wolverine. Activities of sucrose synthase, invertase, galactinol synthase, and a-galactosidase were compared to soluble s...

in order to study of some effective phenologic and physiologic characteristics on 18 sunflower hybrids yield under optimum conditions, an experiment was conducted as randomized complete block design with three replications at the research field of seed and plant improvement institute-karaj in 2006-2007. the result indicated that the hybrids showed significant difference in phonologic characteri...
