Our study describes the clinical outcome of total ankle replacement (TAR) performed in patients with moderate to severe varus deformity. Between September 2004 and September 2007, 23 ankles with a varus deformity > or = 10 degrees and 22 with neutral alignment received a TAR. Following specific algorithms according to joint congruency, the varus ankles were managed by various additional procedu...

the present study aimed to investigate the characteristics of occupational accidents and frequency and severity of work related accidents in the construction industry among iranian insured workers during the years 20072011.the iranian social security organization (isso) accident database containing 21,864 cases between the years 2007-2011 was applied in this study. in the next step, total accid...

non-linear time series models have become fashionable tools to describe and forecast stock market returns in recent years. a significant amount of evidence supports a negative relationship between volume and future returns. this suggests that volume could act as a suitable threshold variable in lstar and tar models. in this research, we compared the forecasting ability of lsatr and tar models w...

The bovine immunodeficiency virus (BIV) Tat protein binds with high affinity to its TAR RNA site through a large set of specific RNA-protein contacts whereas human immunodeficiency virus (HIV) Tat makes relatively few contacts to HIV TAR and requires the assistance of a cellular protein to bind with high affinity. The two TAR sites are structurally very similar, but BIV Tat appears unable to ma...

The ability of the HIV-1 Tat protein to trans -activate HIV-1 transcription in vitro is specifically inhibited by a circular TAR RNA decoy. This inhibition is not overcome by adding an excess of Tat to the reaction but is partially overcome by adding Tat in combination with nuclear extract, suggesting that TAR RNA might function by interacting with a complex containing Tat and cellular factor(s...

INTRODUCTION To compare, in the same cohort of men, the detection of clinically significant disease in standard (STD) cores versus multiparametric magnetic resonance imaging (mpMRI) targeted (TAR) cores. MATERIAL AND METHODS A prospective study was conducted on 129 biopsy naïve men with clinical suspicion of prostate cancer. These patients underwent prebiopsy mpMRI with STD systematic biopsie...

Occupational tar cancer, or the development of malignant epithelial tumors in those whose work entails prolonged exposure to tar or to certain closely related substances, has for many years constituted a recognized clinical entity. The close causal relationship between chemical agent and tumor development apparent in these cases has stimulated numerous attempts during the last forty years to pr...
