In this study we explored predictors and moderators of response to Internet-based cognitive behavioral therapy (CBT) and Internet-based problem-solving therapy (PST) for depressive symptoms. The sample consisted of 263 participants with moderate to severe depressive symptoms. Of those, 88 were randomized to CBT, 88 to PST and 87 to a waiting list control condition. Outcomes were improvement and...

CONTEXT Insufficient evidence exists for recommendation of specific effective treatments for older primary care patients with minor depression or dysthymia. OBJECTIVE To compare the effectiveness of pharmacotherapy and psychotherapy in primary care settings among older persons with minor depression or dysthymia. DESIGN Randomized, placebo-controlled trial (November 1995-August 1998). SETT...

We have examined the expression of platelet phenolsulphotransferase (PST) in 60 individuals. Using an antibody which recognizes both forms of PST present in man (P-PST and M-PST), we determined that the polymorphism of platelet P-PST activity is determined by the level of expression of the enzyme protein. The implications for susceptibility to adverse drug reactions and chemical carcinogenesis ...

Depression is the most common mental health problem reported among dialysis patients. Problem-Solving Therapy (PST) is effective for treating depression in patients with chronic illness, but its acceptability has never been reported in older hemodialysis patients, and its association with health-related quality of life is unknown. We investigated the feasibility and effectiveness of PST in HD p...

Abstract Purpose We investigated the effects of 12 weeks passive static stretching training (PST) on force-generating capacity, stiffness, muscle architecture plantarflexor muscles. Methods Thirty healthy adults participated in study. Fifteen participants (STR, 6 women, 9 men) underwent 12-week muscles PST [(5 × 45 s-on/15 s-off) 2exercises] 5times/week (duration: 2250 s/week), while 15 (CTRL, ...

BACKGROUND Few randomized controlled trials (RCTs) report interventions targeting improvement of frailty status as an outcome. METHODS This RCT enrolled 117 older adults (65-79 years of age) in Toufen, Taiwan who scored 3-6 on The Chinese Canadian Study of Health and Aging Clinical Frailty Scale Telephone Version and then score ≥1 on the Cardiovascular Health Study Phenotypic Classification o...

A purified Shigella enterotoxin (pST) and a cell-free lysate with pST removed (CFL-pST) from the whole-cell lysate of Shigella dysenteriae 60 R were used to study their effect on the myoelectric activity and mucosal integrity of rabbit ileal segments. We have previously defined two myoelectric patterns: the migrating action potential complex and repetitive bursts of action potentials that occur...

Pancreastatin (PST), a regulatory peptide with a general inhibitory effect on secretion, is derived from chromogranin A, a glycoprotein present throughout the neuroendocrine system. We have previously demonstrated the counterregulatory role of PST on insulin action in rat hepatocytes. Here, we are reporting the PST effects on rat adipocytes. PST dose dependently inhibits basal and insulin-stimu...

Forty-eight pigs of three known stress classifications were injected daily with porcine somatotropin (pST; 4 mg/d) or placebo. The effects of pST and stress classification on the sensory, physical and chemical characteristics of loin chops were observed. Chops from pST-treated animals were less tender and juicy than chops from control animals. Positive stress classification also significantly d...

RATIONALE The chromogranin A-derived peptide pancreastatin (PST) is a dysglycemic, counter-regulatory peptide for insulin action, especially in liver. Although previous evidence for a PST binding protein has been reported, such a receptor has not been identified or sequenced. METHODS AND RESULTS We used ligand affinity to purify the PST target, with biotinylated human PST (hCHGA273-301-amide)...
