OBJECTIVE To obtain information about dietary pattern change of Chinese Americans in Pennsylvania and its relationship with demographic characteristics and acculturation indicators. DESIGN A cross-sectional self-administered survey. SUBJECTS A convenience sample of 399 Chinese Americans. Statistical analyses performed t Tests, analysis of variance with(More)
Chinese-American women have a high risk of osteoporosis. However, their calcium intake has been reported previously as considerably below the Dietary Reference Intake. Increasing consumption of calcium-rich foods, many of which are also fortified with vitamin D, is a safe way to increase their calcium and vitamin D intake. This study's objective was to(More)
Sensitivities of Helicoverpa armigera (Hübner) field populations to Bacillus thuringiensis (Bt) insecticidal protein CrylAc were monitored during 1998-2000 in China. A total of 41 strains was sampled, and most of them were collected from Bt cotton planting regions. The range of IC50 values (concentration producing 50% inhibition of larval development to(More)
OBJECTIVE To investigate the family food system in first-generation Chinese American families. DESIGN Qualitative interviews using reciprocal determinism constructs to understand influences on food choices. SETTING Weekend Chinese schools in Pennsylvania. PARTICIPANTS Twenty couples with at least 1 child aged 5 or older enrolled in a Chinese school in(More)
OBJECT Unruptured posterior communicating artery (PCoA) aneurysms with oculomotor nerve palsy (ONP) have a very high risk of rupture. This study investigated the hemodynamic and morphological characteristics of intracranial aneurysms with high rupture risk by analyzing PCoA aneurysms with ONP. METHODS Fourteen unruptured PCoA aneurysms with ONP, 33 ruptured(More)
OBJECTIVES To assess the diagnosis value of 18-FDG-PET in estimating disease activity in Takayasu arteritis. METHODS A complete search of PubMed, EMBASE and The Cochrane Library was finished to July 25, 2012. Sensitivity and specificity as well as pooled estimates of positive and negative likelihood ratios (PLR and NLR) were calculated by Meta-Disc. We(More)
BACKGROUND The management of small, unruptured intracranial aneurysms is still controversial. Given the distinctive natural history of aneurysm at different locations, location-specific analysis might be a reasonable approach. This study aimed to investigate morphological discriminators for rupture status by focusing on only posterior communicating artery(More)
BACKGROUND AND PURPOSE The conflicting findings of previous morphological and hemodynamic studies on intracranial aneurysm rupture may be caused by the relatively small sample sizes and the variation in location of the patient-specific aneurysm models. We aimed to determine the discriminators for aneurysm rupture status by focusing on only posterior(More)
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized clinically by memory and cognitive dysfunction. Unfortunately, there is no effective therapeutic method for AD treatment or ways to halt disease progression. Many mechanisms are involved in the disease, including genes mutation and protein dysfunction. RNA interference (RNAi)(More)
NuCOTN 33B, a Bt transgenic variety of upland cotton (Gossypium hirsutum L.) expressing the insecticidal protein Cry1Ac from Bacillus thuringiensis Berliner sp. kurstaki, was evaluated for resistance to Helicoverpa armigera (Hübner) during 1998-2000 in northern China. The results indicated that there was no significant difference in egg densities between(More)
