Debate about the nature of evolutionary and developmental information has, until now, reliably foundered between the Scylla of meaning and the Charybdis of causation. The idea that the genome carries semantic information promises an attractive conceptual analysis of talk about genes for eye colour or for breast cancer. This analysis has proved elusive. Genes are not invested with meaning in the...

PURPOSE The purpose of this study was to compare ultrasound results with results of scintigraphy and targeted cytological puncture of a nodule or nodules of the thyroid. MATERIAL AND METHOD The study analyzed results of 133 patients, men and women, between age of 16 and 75. The patients had a standard ultrasound of the thyroid, scintigraphy and ultrasound guided cytological puncture. RESULT...

background : invasive ductal carcinoma is one of the most common type of tumors in females, constituting a single large group of breast cancers. there are various prognostic factors, of which tumor grade, size and axillary lymph node metastasis are among the important ones. fine needle aspiration cytology is a commonly used diagnostic technique in the initial evaluation of breast lumps. in the ...

Invasive alien species can have serious adverse impacts on both the environment and the economy. Being able to predict the impacts of an alien species could assist in preventing or reducing these impacts. This study aimed to establish whether there are any life history traits consistently correlated with the impacts of alien birds across two continents, Europe and Australia, as a first step tow...

Taxol and Taxotere propagate apoptosis in Jurkat T cells via molecular signals that coincide with the appearance of two distinct cell populations. Cell cycle arrest in G2-M phase and activation of cell cycle-dependent kinases begin within 2 h and extend to most cells by 16 h. Phosphorylation of Bcl-2 also begins within 2 h and intensifies from 2-16 h. Cell cycle arrest, activation of mitotic ki...
