results of the 133 breast lesions, 32 were malignant and 101 were benign. in the differentiation of benign and malignant lesions, conventional us resulted in sensitivity of 100 %, specificity of 43.0 %, ppv of 57.1 %, npv of 36.7 %, and accuracy of 100 %. regarding swe, the sensitivity, specificity, ppv, npv, and accuracy values based on emax were 84.4 %, 89.1 %, 71.1 %, 94.7 %, and 88.0 %, res...

objectives this double-blind randomized clinical trial assessed the effects of dried leave of s. hortensis on the serum sugar levels, lipid profiles, high-sensitivity crp (hs-crp), and blood pressures of 60 metabolic syndrome patients referred to the healthy heart institute in shiraz, iran during 2013. materials and methods first, components from the essential oil of the plant powder were ident...

PURPOSE To investigate the effects of laser photocoagulation (LP)-induced ocular hypertension (OHT) on the survival and retrograde axonal transport of retinal ganglion cells (RGC), as well as on the function of retinal layers. METHODS Adult albino Swiss mice (35-45 g) received laser photocoagulation of limbal and episcleral veins in the left eye. Mice were sacrificed at 8, 17, 35, and 63 days...

Investigations on juvenile American shad (Alosa sapidissima) revealed several physiological changes associated with downstream migration. Plasma chloride decreased 20% in wild juvenile shad during the autumn migration. Migrants had lower condition factor and hematocrit than non-migrant shad captured by beach seining. Gill Na+,K+-ATPase activity of migrant shad was higher than non-migrant; a 2.5...

Acetyl-CoA carboxylase is generally considered to have an important role in the regulation of fatty acid synthesis and overall there is good evidence that short-term control of this pathway by insulin and other hormones involves changes in activity of this enzyme (for recent reviews see Brownsey & Denton, 1985, 1986). The first demonstration of the short-term hormonal regulation of this enzyme ...

Freshwater sponges in the Great Lakes St. Lawrence River system overgrow and kill introduced zebra (Dreissena pulymorpkza) and quagga mussels (DreisLse?aa bugerasis) on solid substrates. Sponges overgrow and smother mussel siphons, thereby interfering with normal feeding and respiration. We tested the significance of sponge-enhanced mussel mortality by repeated sampling at several sites where b...

The purpose of this report is to provide a summary of recent studies on South Pacific albacore and highlight the key issues for PICTs to consider in the management of their domestic longline fisheries. The current (2005) stock assessment for South Pacific albacore concluded that there are no sustainability concerns regarding the overall stock and substantially higher yields could be taken from ...

Age-related changes in the capacity, rate, and modulation of dopamine (DA) uptake within the striatum and the nucleus accumbens core of Fischer 344 rats were investigated using in vivo electrochemical recordings coupled with local drug application techniques. Equimolar amounts of DA were pressure ejected into the striatum and the nucleus accumbens of 6-, 12-, 18-, and 24-month old rats. The DA ...

We examined the effects of water velocity on prey detection and capture by drift-feeding juvenile coho salmon (Oncorhynchus kisutch) and steelhead (sea-run rainbow trout, Oncorhynchus mykiss irideus) in laboratory experiments. We used repeated-measures analysis of variance to test the effects of velocity, species, and the velocity x species interaction on prey capture probabiJity, prey detectio...

Stimulation with weak electrical direct currents has been shown to be capable of inducing stimulation-polarity-dependent prolongeddiminutions or elevations of cortical excitability, most probably elicited by a hyperor depolarization of resting membrane potentials.The aim of the present study was to test if cognitive task and motor exercise practiced during the stimulation are able t...
