Ascites sarcoma BP8 cells, cultured in suspension in vitro were used as a general toxicity test system for tobacco and tobacco smoke constituents. Some 250 compounds, representative of these materials, were examined by exposing cells to different concentrations of these constituents and measuring

Cell-free translation in Krebs-2 extracts was optimized for RNAs of two plant viruses; potato virus X (PVX, potexvirus), and tobacco mosaic virus (TMV, tobamovirus). PVX and TMV RNAs programmed synthesis of similar sets of polypeptides in both the Krebs-2 extracts and the rabbit reticulocyte

The 5'-untranslated leader sequence of potato virus X (PVX) RNA (63 nucleotides apart from cap-structure) consists of two sub-sequences referred to as alpha-sequence (41 nucleotides with no G) and beta-sequence (42 nucleotides upstream from the first AUG). Computer-based folding predictions suggest

Thoracic endometriosis is a rare entity characterized by presence of endometrial tissue in pleura, lung parenchyma or airways. Most frequent manifestations are catamenial pneumothorax, hemothorax, hemoptysis and pulmonary nodules. We report here a rare case of a woman with thoracic endometriosis who
Pyrimidine tract binding protein strongly stimulates in vitro encephalomyocarditis virus RNA translation at the level of preinitiation complex formation.

Cellular protein p57/58, now known to be identical to polypyrimidine tract binding protein (PTB), has earlier been shown to specifically bind to the internal ribosome entry sites (IRES) of encephalomyocarditis virus (EMCV) and some other picornaviral RNAs. To elucidate its relevance to the internal

A factor from rabbit-reticulocyte ribosome, which stimulates by 5-fold initiation of hemoglobin mRNA translation in Krebs ascites cell extracts, was purified to homogeneity. The factor, a protein of about 65,000 molecular weight in sodium dodecyl sulfate, discriminates between various mRNAs: it

Several fractions of RNA prepared from the post-ribosomal cytosol of sheep lymphoid cells were found to include messenger-like RNA as defined by the following criteria: a, template activity, i.e. the ability to promote the incorporation of radioactive amino acids into protein in cell-free
Nonhepatic cancer in liver cirrhosis: a retrospective study of prevalence, complication rate after specific oncological treatment, follow-up and prognostic predictors of outcome in 354 patients with cirrhosis.

BACKGROUND
Nonhepatic cancer risk of cirrhotic patients seems to be increased. Major surgery and chemotherapy in cirrhosis are associated with increased mortality and morbidity, which limits treatment.
OBJECTIVE
The aims of this study were analysis of (a) prevalence, (b) outcome after treatment, (c)

Two species of glutamine tRNA were isolated from mouse liver and their nucleotide sequences were determined. The minor glutamine tRNA(tRNA(UmUGGln)) that possesses UmUG (where Um stands for 2'-O-methyluridine) as the anticodon sequence was found to have suppressor activity for the UAG termination

BACKGROUND
Previous studies on patients with hip fractures and in patients with colorectal cancer have documented that perioperative transfusion is associated with a significant increase in postoperative infection rate. Therefore, we sought to investigate the incidence of preoperative and

BACKGROUND
Surgical site infections (SSI) are the most common nosocomial infection in surgical patients, accounting for 38% of all such infections, and are a significant source of postoperative morbidity resulting in increased hospital length of stay and increased cost. During 1986-1996 the Center
