Pigs were weaned at 16 to 20 days of age and fed diets containing either dried whey, dried porcine solubles (DPS), or condensed porcine solubles (CPS) for 3 weeks, followed by a common diet for 2 weeks. The results of the trial showed that 5% of either DPS or CPS can replace dried whey protein in diets for weanling with no effect on growth performance up to 5 weeks after weaning

Strong electrical stimulation (ES) of the frog glossopharyngeal (GP) efferent nerve induced slow depolarizing potentials (DPs) in taste cells under hypoxia. This study aimed to elucidate whether the slow DPs were postsynaptically induced in taste cells. After a block of parasympathetic nerve (PSN) ganglia by tubocurarine, ES of GP nerve never induced slow DPs in the taste cells, so slow DPs wer...

OBJECTIVES Dried blood spots (DBS) and dried plasma spots (DPS) are easy to collect and store, and have been successfully tested as an alternative to plasma for performing virological analyses. Adequate storage conditions still need to be established and cell-associated proviral DNA in DBS can contribute to the amplified products. We evaluated these two parameters. METHODS Residual samples fr...

As a result of the cochlea's nonlinear mechanics, stimulation by two tones results in the generation of distortion products (DPs) at frequencies flanking the primary tones. DPs are measurable in the ear canal as oto-acoustic emissions, and are used to noninvasively explore cochlear mechanics and diagnose hearing loss. Theories of DP emissions generally include both forward and reverse cochlear ...

Dps (DNA protection during starvation) proteins, mini-ferritins in the ferritin superfamily, catalyze Fe(2+)/H(2)O(2)/O(2) reactions and make minerals inside protein nanocages to minimize radical oxygen-chemistry (metal/osmotic/temperature/nutrient/oxidant) and sometimes to confer virulence. Paired Dps proteins in Bacillus, rare in other bacteria, have 60% sequence identity. To explore function...

PURPOSE Dynamic visual acuity (DVA) is a relatively independent parameter for evaluating the ability to distinguish details of a moving target. The present study has been designed to discuss the extent to which age-related cataract impacts DVA in elderly individuals and to determine whether it could be restored after bilateral phacoemulsification combined with intraocular lens implantation surg...

GOALS We designed this study to evaluate the efficacy of spleen salvage during distal pancreatectomy for patients with benign and borderline malignant tumors. BACKGROUND Despite the emphasis on its role, the spleen has commonly been removed in distal pancreatectomy. STUDY From January 2005 to July 2009, 82 patients underwent distal pancreatectomy with splenectomy (DPS) and 78 patients under...

Dps proteins, bacterial mini-ferritins that protect DNA from oxidative stress, are implicated in the survival and virulence of pathogenic bacteria. Here we examine the mechanism of E. coli Dps protection of DNA, specifically whether this DNA-binding protein can utilize DNA charge transport through the base pair π-stack to protect the genome from a distance. An intercalating ruthenium photooxida...

BACKGROUND The use of simplified methods for viral load determination could greatly increase access to treatment monitoring of HIV patients in resource-limited countries. OBJECTIVE The aim of the present study was to optimize and evaluate the performance of the Roche COBAS Taqman assay in HIV-RNA quantification from dried blood spots (DBS) and dried plasma spots (DPS). STUDY DESIGN EDTA blo...
