Head and neck squamous cell carcinoma (HNSCC) patients are at an increased risk of developing a second primary tumor (SPT) or recurrence following curative treatment. 13-cis-retinoic acid (13-cRA) has been tested in chemoprevention clinical trials, but the results have been inconclusive. We genotyped 9,465 single nucleotide polymorphisms (SNP) in 450 patients from the Retinoid Head and Neck Sec...

We use a regression discontinuity design to investigate the effect of the Community Reinvestment Act on consumer credit outcomes using data from the Federal Reserve Bank of New York’s Consumer Credit Panel database (Equifax data) for the years 2004 to 2012. A bank’s activities in census tracts with median family incomes less than 80 percent of the metropolitan statistical area (MSA) median fami...

The objective of the present research was to determine the frequency of slime production by Staphylococcus aureus strains recovered from bovine mastitis and comparison of slime formation frequency, depending on the determination procedure employed. The investigations embraced 59 Staphylococcus aureus strains obtained from the inflammatory secretion of mammary glands of 45 cows. Slime production...

13-c/s-Retinoic acid (13-CRA) is a synthetic analog of vitamin A effective in reversing preneoplastic lesions in both humans and animals. To study its physicochemical properties and disposition kinetics, we developed a rapid, sensitive, and pre cise high-performance liquid chromatography assay for 13CRA in biological samples. This assay system resulted in a clear separation of 13-CRA from all-f...

Biofilm-forming ability is increasingly being recognized as an important virulence factor in several Staphylococcus species. This study evaluated the biofilm-forming ability of sixty canine derived clinical isolates of S. pseudintermedius, using three phenotypic methods, microtiter plate test (MtP), Congo red agar method (CRA) and tube adherence test, and the presence and impact of biofilm-asso...

BACKGROUND Existing data evaluating the impact of metformin on the colorectal adenoma (CRA) risk in patients suffering from type 2 diabetes (T2D) are limited and controversial. We therefore summarized the studies currently available and assessed the relationship between metformin treatment and risk of CRA in T2D patients. METHODS We systematically searched databases for eligible studies that ...

Three kinds of Cr(II) ions are present on CO reduced Cr0 3 /S i0 2 samples (labelled A, B. and C), having two, three and four oxygen ligands before chemisorption, respectively. The population of CrA , CrB and Cr c on a standard sample is evaluated to be: 52%, 28%, 20%, respectively. The number of oxygen ligands determines the actual charge of the ions, increasing in the series A, B, and C, as w...

PURPOSE Lifelong control of disease processes associated with dental caries should be an essential part of the process of care for practicing dental hygienists. The purpose of this study was to identify the knowledge, attitudes and practice behaviors among dental hygienists regarding caries risk assessment (CRA) and management. METHODS Utilizing the American Dental Hygienists' Association (AD...

Collision resolution algorithms (CRA’s) for the ternary feedback multiple access channel with time constraints are considered. We wish to maximize the number of packets successfully transmitted within a fixed deadline li after their arrival for transmission. Packet arrivals are assumed to be Poisson. A nonnested CRA is described and its performance is compared with a nested CRA for values of li...

By screening 720 natural compounds in a standard 2-way allogeneic mixed leukocyte reaction assay, we identified a potent immunosuppressive capacity of crassin acetate (CRA), a coral-derived cembrane diterpenoid. CRA efficiently inhibited allogeneic mixed leukocyte reaction as well as antigen-specific activation of CD4 T cells by bone marrow-derived dendritic cells (DCs). With regard to cellular...
