Vitronectin (Vn), a multifunctional adhesive protein, is found in association with tumor progression, angiogenesis and metastasis in a variety of (human) tumors. But no studies concerning its correlation to osteosarcoma prognosis were found. Hence, we aimed to investigate the prognostic value of Vitronectin (Vn) in osteosarcoma. Here, we studied the expression of VN in the tumor tissues from 67...

When nanoparticles (NPs) are exposed to the biological environment, their surfaces become covered with proteins and biomolecules (e.g. lipids). Here, we report that this protein coating, or corona, reduces the targeting capability of surface engineered NPs by screening the active sites of the targeting ligands.

Citrullination, a posttranslational modification of peptidyl arginine to citrulline, plays an essential role in rheumatoid arthritis (RA). Citrullination is catalyzed by a group of peptidylarginine deiminases (PADs) including PADI 1, 2, 3, 4 and 6. Many studies have indicated that the gene encoding PADI4 is a factor in susceptibility to RA. Some studies have detected PADI2 expression in RA syno...

Breast cancer remains one of the leading causes of cancer deaths among women.[1] Simple mastectomy is a common surgical procedure that is used in the management of breast cancer. Seroma is one of the most frequently encountered complications following mastectomy and is a serous fluid that accumulates in the space between the skin flap and underlying tissues. It may cause significant morbidity, ...

BRENT EDWARD INSKO: Passive Haptics Significantly Enhances Virtual Environments (Under the direction of Frederick P. Brooks, Jr.) One of the most disconcertingly unnatural properties of most virtual environments (VEs) is the ability of the user to pass through objects. I hypothesize that passive haptics, augmenting a high-fidelity visual virtual environment with low-fidelity physical objects, w...

Nicotine addiction is associated with many lethal disorders (cancer, cardiovascular and pulmonary disease), and more effective medications to aid smoking cessation are urgently needed. Anatabine is 1 of the most abundant minor tobacco alkaloids, but relatively little is known about its interactions with the abuse-related effects of nicotine. The acute effects of anatabine or saline on nicotine-...

Little consideration has been given to the effect of different segmentation methods on the variability of data derived from microarray images. Previous work has suggested that the significant source of variability from microarray image analysis is from estimation of local background. In this study, we used Analysis of Variance (ANOVA) models to investigate the effect of methods of segmentation ...

Objective. We aim to investigate whether centenarians are significantly more resilient than younger elders and whether resilience significantly contributes to exceptional longevity. Data. We use a unique dataset from the Chinese Longitudinal Healthy Longevity Survey with the largest sample to date of centenarians, nonagenarians, octogenarians, and a compatible group of young old aged 65-79. Met...
