Department of Biomedical Engineering, University of California, Davis
Microfluidic flow chambers etched by photolithography and fabricated from PDMS are applied to probe functional outcomes associated with EC dysfunction and inflammation. In a representative experiment, the ability of differential shear stress to modulate monocytic cell adhesion to cytokine activated EC monolayers is demonstrated.

Psycho-oncology. Sep, 2011 | Pubmed ID: 21915940
Some individuals are able to gain psychological benefits from illness and adversity, such as a greater sense of purpose and closer relationships, termed 'benefit finding' (BF). The main aim of this study was to explore the extent to which BF is reported in patients with head and neck cancer (HNC). Secondary aims were to establish the relationships between BF, other patient-reported outcomes and predictive factors such as coping strategy and level of optimism.
Achyranthes Aspera (Apamarg) Leaf Extract Inhibits Human Pancreatic Tumor Growth in Athymic Mice by Apoptosis
Journal of Ethnopharmacology. Jul, 2012 | Pubmed ID: 22640722
Achyranthes aspera (Family Amaranthacea) is used for cancer therapy by ayurvedic medical practitioners in India. However, due to the non formal nature of its use, there are no systematic studies validating its medicinal properties. Thus, it's utility as an anti cancer agent remains anecdotal. Earlier, we demonstrated A. aspera to exhibit time and dose-dependent preferential cytotoxicity to cultured human pancreatic cancer cells. In this report we validate in vivo anti tumor properties of A. aspera.
A Contrast Transfer Function Approach for Image Calculations in Standard and Aberration-corrected LEEM and PEEM
Ultramicroscopy. Apr, 2012 | Pubmed ID: 22209472
We introduce an extended Contrast Transfer Function (CTF) approach for the calculation of image formation in low energy electron microscopy (LEEM) and photo electron emission microscopy (PEEM). This approach considers aberrations up to fifth order, appropriate for image formation in state-of-the-art aberration-corrected LEEM and PEEM. We derive Scherzer defocus values for both weak and strong phase objects, as well as for pure amplitude objects, in non-aberration-corrected and aberration-corrected LEEM. Using the extended CTF formalism, we calculate contrast and resolution of one-dimensional and two-dimensional pure phase, pure amplitude, and mixed phase and amplitude objects. PEEM imaging is treated by adapting this approach to the case of incoherent imaging. Based on these calculations, we show that the ultimate resolution in aberration-corrected LEEM is about 0.5 nm, and in aberration-corrected PEEM about 3.5 nm. The aperture sizes required to achieve these ultimate resolutions are precisely determined with the CTF method. The formalism discussed here is also relevant to imaging with high resolution transmission electron microscopy.
Cell. Mar, 2012 | Pubmed ID: 22424236
Personalized medicine is expected to benefit from combining genomic information with regular monitoring of physiological states by multiple high-throughput methods. Here, we present an integrative personal omics profile (iPOP), an analysis that combines genomic, transcriptomic, proteomic, metabolomic, and autoantibody profiles from a single individual over a 14 month period. Our iPOP analysis revealed various medical risks, including type 2 diabetes. It also uncovered extensive, dynamic changes in diverse molecular components and biological pathways across healthy and diseased conditions. Extremely high-coverage genomic and transcriptomic data, which provide the basis of our iPOP, revealed extensive heteroallelic changes during healthy and diseased states and an unexpected RNA editing mechanism. This study demonstrates that longitudinal iPOP can be used to interpret healthy and diseased states by connecting genomic information with additional dynamic omics activity.
American College of Rheumatology 2012 Recommendations for the Use of Nonpharmacologic and Pharmacologic Therapies in Osteoarthritis of the Hand, Hip, and Knee
Arthritis Care & Research. Apr, 2012 | Pubmed ID: 22563589
To update the American College of Rheumatology (ACR) 2000 recommendations for hip and knee osteoarthritis (OA) and develop new recommendations for hand OA.
Systemic Lupus Erythematosus with Sjögren Syndrome Compared to Systemic Lupus Erythematosus Alone: a Meta-analysis
Journal of Clinical Rheumatology : Practical Reports on Rheumatic & Musculoskeletal Diseases. Jan, 2012 | Pubmed ID: 22157271
This study aimed to compare the difference of the clinical and laboratory features of the patients between the combined systemic lupus erythematosus (SLE) and Sjögren syndrome (SLE-SS) and SLE only.
Parkinsonism & Related Disorders. Jan, 2012 | Pubmed ID: 21917501
Although non-motor manifestations of Parkinson's disease are common and can cause severe disability, they are often under-recognized, leading to missed treatment opportunities. Screening tools for non-motor symptoms are urgently needed. Recently a 30-item screening Non Motor Symptoms Questionnaire was developed. Although some psychometric properties have been evaluated, sensitivity and specificity of the questionnaire have not been systematically assessed.
