PURPOSE To determine whether children with specific language impairment (SLI) show deficits in lexical-semantic organization and, if so, whether these deficits are commensurate with their delay in vocabulary size and whether the deficits affect all children with SLI. METHOD Fourteen children with SLI, 14 age matches (AM), and 14 expressive vocabulary(More)
Modulation of drug transporters via herbal medicines which have been widely used in combination with conventional prescription drugs may result in herb-drug interactions in clinical practice. The present study was designed to investigate the inhibitory effects of 50 major herbal constituents on P-glycoprotein (P-gp) in vitro and in vivo as well as related(More)
This paper studies the algorithmic issues of the spanning star forest problem. We prove the following results: (1) There is a polynomial-time approximation scheme for planar graphs; (2) there is a polynomial-time 3 5 -approximation algorithm for graphs; (3) it is NP-hard to approximate the problem within ratio 259 260 + for graphs; (4) there is a(More)
OBJECTIVE To test the hypothesis that prevalence of women with menopausal symptoms of hot flushes; aches, joint pain, and stiffness; depressed mood; poor sleep; decreased libido; or vaginal dryness increases with progression through the menopausal transition. METHODS Women in the Penn Ovarian Aging Study were assessed longitudinally for 9 years. Data were(More)
IL-10-producing B cells (B10 cells) have been shown to play a suppressive role in the peripheral blood of humans, with their numbers and function altered in several autoimmune diseases. However, the role of B10 cells in Graves' disease (GD) remains unknown. In this study, we demonstrated that B10 cells in human peripheral blood belonged to a CD24(hi)CD27(+)(More)
A simple, rapid and sensitive method was developed for the simultaneous quantification of four active schisandra lignans (schisandrin, schisantherin A, deoxyshisandrin and gamma-schisandrin) from a traditional Chinese medicine Schisandra chinensis(Wuweizi) in rat plasma using a high-performance liquid chromatography system coupled to a positive ion(More)
This paper studies the algorithmic issues of the spanning star forest problem. We prove the following results: (1) there is a polynomial-time approximation scheme for planar unweighted graphs; (2) there is a polynomial-time algorithm with approximation ratio 3/5 for unweighted graphs; (3) it is NP-hard to approximate the problem within ratio 545/546 +(More)
Agonists of the peroxisome proliferator-activated receptor alpha (PPARalpha) and gamma (gamma) exert anti-proliferative and anti-inflammatory effects that led to the testing of these drugs in experimental cardiac hypertrophy. However, the effect of PPAR beta/delta (beta/delta) agonists in hypertrophy is not yet known. In this paper, an experiment was(More)
