eW have used electron microscopy and single-particle image processing to study head conformation in myosin V molecules. We find that in the presence of ATP, many heads have a sharply angled...

Genome-wide association tests by using block information in family data

Tang, Rui, Wang, Fei, Sha, Qiuying, Zhang, Shuanglin, Chen, Huann-Sheng

By applying an association test to analyze the data sets from Genetic Analysis Workshop 15 Problem 3, we compare power using different haplotype-block information. The results from using both of the...

Cytotoxicity of Poly(Phenolic)Sulfonates and Their Sodium Salts in L1210 Lymphoid Leukemia Cells

Wang, Fei, Warren, Amy E., Barnes, Cheryl R., Hall, Iris H.

Poly(phenolic)-sulfonates demonstrated very good cytotoxicity against the growth of tumor cell lines (L1210, Tmolt-3, HeLa-S3) and are comparable in potency with typical clinically used anticancer...

Identifying Future High-Healthcare Users: Exploring the Value of Diagnostic and Prior Utilization Information

Amy K. Rosen, Fei Wang, Maria E. Montez, Carter C. Rakovski, Dan R. Berlowitz, Jaime C. Lucove

Objective: Diagnosis-based risk-adjustment measures are increasingly being promoted as disease management tools. We compared the ability of several types of predictive models to identify future...

Development of a Microsurgery Training System

Wang, Fei, Su, Eileen, Burdet, Etienne, Bleuler, Hannes

Surgeons require significant training to acquire sufficient dexterity and hand-eye coordination to manipulate objects skilfully under the microscope. This paper presents a computer-based real-time...

A Real-Time Simulator for Interventional Radiology

Duratti, Lindo, Wang, Fei, Samur, Evren, Bleuler, Hannes

Interventional radiologists manipulate guidewires and catheters and steer stents through the patient’s vascular system under X-ray imaging for treatment of vascular diseases. The complexity of...

RACK1 Regulates Directional Cell Migration by Acting on Gβγ at the Interface with Its Effectors PLCβ and PI3Kγ

Chen, Songhai, Lin, Fang, Shin, Myung Eun, Wang, Fei, Shen, Lixin, Hamm, Heidi E.

Migration of cells up the chemoattractant gradients is mediated by the binding of chemoattractants to G protein–coupled receptors and activation of a network of coordinated excitatory and...

A single amino acid substitution in ORF1 dramatically decreases L1 retrotransposition and provides insight into nucleic acid chaperone activity

Martin, Sandra L., Bushman, Diane, Wang, Fei, Li, Patrick Wai-Lun, Walker, Ann, Cummiskey, Jessica, ...

L1 is a ubiquitous interspersed repeated sequence in mammals that achieved its high copy number by autonomous retrotransposition. Individual L1 elements within a genome differ in sequence and...

Fusarium Graminearum Growth Inhibition Due to Glucose Starvation Caused by Osthol

Shi, Zhiqi, Shen, Shouguo, Zhou, Wei, Wang, Fei, Fan, Yongjian

The effects of osthol, a plant coumarin, on morphology, sugar uptake and cell wall components of Fusarium graminearum were examined in vitro by electron microscopy,14C-labelling and enzyme activity...

SIRT2 Suppresses Adipocyte Differentiation by Deacetylating FOXO1 and Enhancing FOXO1's Repressive Interaction with PPARγ

Wang, Fei, Tong, Qiang

Sirtuin family of proteins possesses NAD-dependent deacetylase and ADP ribosyltransferase activities. They are found to respond to nutrient deprivation and profoundly regulate metabolic functions. We...

Retroviral Nucleocapsid Proteins Display Nonequivalent Levels of Nucleic Acid Chaperone Activity ▿

Stewart-Maynard, Kristen M., Cruceanu, Margareta, Wang, Fei, Vo, My-Nuong, Gorelick, Robert J., Williams, Mark C., ...

Human immunodeficiency virus type 1 (HIV-1) nucleocapsid protein (NC) is a nucleic acid chaperone that facilitates the remodeling of nucleic acids during various steps of the viral life cycle. Two...

The role of GTP binding and hydrolysis at the atToc159 preprotein receptor during protein import into chloroplasts

Wang, Fei, Agne, Birgit, Kessler, Felix, Schnell, Danny J.

The majority of nucleus-encoded chloroplast proteins are targeted to the organelle by direct binding to two membrane-bound GTPase receptors, Toc34 and Toc159. The GTPase activities of the receptors...
