The risks vs benefits of tricuspid valve (TV) surgery in reoperative patients requiring left-sided valve surgery and moderate-to-severe tricuspid regurgitation is unclear. We compared patients with and without concomitant TV surgery. A total of 200 patients with moderate-to-severe TV regurgitation had reoperative left-sided valve procedures from January 2002 to April 2014; 75 with TV interventi...

The aim of this study was to compare image noise properties of GE Discovery HD 750 and Toshiba Aquilion ONE. The uniformity section of a Catphan 600 image quality assurance phantom was scanned with both scanners, at different dose levels and with extension rings simulating patients of different sizes. 36 datasets were obtained and analyzed in terms of noise power spectrum. All the results prove...

BACKGROUND The aim of this study was to examine the effect of different reference ranges in bone mineral density on the diagnosis of osteoporosis. METHODS This cross-sectional study involved 357 men and 870 women aged between 18 and 89 years, who were randomly sampled from various districts within Ho Chi Minh City, Vietnam. BMD at the femoral neck, lumbar spine and whole body was measured by ...

The objective of this research was to study of color and oxidation changes in camel meat during storage. In this study longissiums muscles of camel meat were excised and stored at 4±1. Lipid oxidation, TVN, Colour and sensory Characteristics were determined. For color, L* and b* increased during storage but a*and croma decreased with time. TVN increased over time during storage. Our study showe...

INTRODUCTION Antiangiogenic drugs were originally designed to starve tumors by cutting off their vascular supply. Unfortunately, when these agents are used as monotherapy or in combination with chemotherapy, they provide only modest survival benefits in the order of weeks to months in most cancer patients. Strategies normalizing the disorganized tumor vasculature offer the potential to increase...

In recent years, there has been an increasing interest in using food additives from natural sources to improve taste and also extend the shelf-life of semi-preserved foodstuffs. The aim of this study was to examine the chemical and microbiological changes promoted by a local marinating process in rainbow trout fillets during chilled storage. Fish fillets were immersed in marinades and stored at...

The samples were stored at -18oC and undergone microbial analysis, chemical characteristics and sensory evaluation at 2-month intervals. Mean bacterial loads and coliform counts were 7.1×10±2.0×10 and 1.9×10±7.1×10 CFU/g. In this study, frozen storage was more effective than either treatment alone at decreasing total and coliform counts. Microbial analysis indicated that freezing storage had a ...

We explore the use of the recently proposed 'total nuclear variation' (TVN) as a regularizer for reconstructing multi-channel, spectral CT images. This convex penalty is a natural extension of the total variation (TV) to vector-valued images and has the advantage of encouraging common edge locations and a shared gradient direction among image channels. We show how it can be incorporated into a ...

This case study is of an 82-year-old lady who was widowed and lives alone in a council house. A left lateral leg ulcer had developed over the gaiter area, and the community team were asked to assess in 2004. The main issues were her inability to tolerate compression (even when reduced) because of the pain. Nevertheless, the community nurses had tried very hard with compression, using different ...

Previous antitumor angiogenesis strategies have focused on targeting angiogenic signals. Encouragingly, the metabolism of tumor endothelial cells (TECs) has gained attention as a therapeutic target in recent years. There is consensus that, in terms of antitumor angiogenesis, the promotion of tumor vascular regression and normalization of the remaining blood vessels are equally important. Presen...
