Compared the effects of 2 psychotherapies based on divergent conceptualizations of depression in later life. Seventy-five older adults diagnosed with major depressive disorder were assigned randomly to problem-solving therapy (PST), reminiscence therapy (RT), or a waiting-list control (WLC) condition. Participants in PST and RT were provided with 12 weekly sessions of group treatment. Dependent...

The present study was performed to examine the response of leptin and leptin receptor (Rb) genes to porcine somatotropin (pST) stimuli in finishing pigs. Twelve crossbred barrows (Yorkshire x Landrace) were used in this study. Animals were individually fed a basal diet containing 18% CP, 1.2% lysine, and 3.5 Mcal of DE/kg ad libitum (as-fed basis). At 90 kg, six pigs were treated with daily inj...

Chromogranin A knockout (Chga-KO) mice exhibit enhanced insulin sensitivity despite obesity. Here, we probed the role of the chromogranin A-derived peptide pancreastatin (PST: CHGA(273-301)) by investigating the effect of diet-induced obesity (DIO) on insulin sensitivity of these mice. We found that on a high-fat diet (HFD), Chga-KO mice (KO-DIO) remain more insulin sensitive than wild-type DIO...

Here we report the cloning and preliminary characterization of the Pst I restriction-modification system of Providencia stuartii 164. Transformants of Escherichia coli carrying the Pst I gene system inserted into the cloning vector pBR322 were selected on the basis of acquired resistance to bacteriophage lambda infection. Pst I endonuclease was detected in osmotic shock fluid from each of the r...

The mining of outliers (or anomaly detection) in large databases continues to remain an active area of research with many potential applications. Over the last several years many novel methods have been proposed to efficiently and accurately mine for outliers. In this paper we propose a unique approach to mine for sequential outliers using Probabilistic Suffix Trees (PST). The key insight that ...

Quantification of myocardial perfusion using first-pass magnetic resonance imaging (MRI) is hampered by respiratory motion of the heart. Prospective slice tracking (PST) potentially overcomes this problem, and may provide an attractive alternative or supplement to current breath-hold techniques. This study demonstrates the feasibility of patient-adapted 3D PST on a 3.0 Tesla MR system. Eight pa...

This research describes the preparation and sensor applications of multifunctional monodisperse, Fe₃O₄ nanoparticles-embedded poly(styrene)/poly(thiophene) (Fe₃O₄-PSt/PTh), core/shell nanoparticles. Monodisperse Fe₃O₄-PSt/PTh nanoparticles were prepared by free-radical combination (mini-emulsion/emulsion) polymerization for Fe₃O₄-PSt core and oxidative seeded emulsion polymerization for PTh she...

A multisector model was formulated to simulate the effects of recombinant porcine somatotropin (pST) on the U.S. hog-pork industry. A producer sector submodel was specified for nine hog-producing states, and a retail-wholesale sector was specified on a national level. Four pST adoption scenarios were tested; these differed in the extent of feed cost reduction (15 vs 25%) with or without premium...

Training models that incorporate case supervision in addition to didactic instruction appear to be effective in maximizing clinicians' proficiency in evidence-based treatments (EBTs). However, it is unknown the extent to which these models promote sustained adoption of EBTs. We describe the results of an online survey on post-training utilization of an EBT, problem-solving therapy (PST), among ...

AIM To identify breast cancer subtypes likely to respond to primary systemic therapy (PST or neoadjuvant therapy) and to assess the accuracy of physical examination (PE) and breast ultrasonography (US) in evaluating and predicting residual size of breast carcinoma following PST. METHODS 116 patients who received at least two cycles of PST between 1998 and 2009 were selected from a prospective...
