[Renal failure stages as predictors of mortality following acute coronary syndrome].

Introduction: renal glomerular filtration rate on hospital admission in patients presented with an acute coronary syndrome as a predictor for mortality.

Patients And Methods: The study analysed 290 patients admitted on hospital with an acute coronary syndrome during one year (2003). Renal function was estimated using the renal glomerular filtration rate by the MDRD formula.

Secretion and properties of a hybrid Kluyveromyces lactis-Aspergillus niger beta-galactosidase.

Background: The beta-galactosidase from Kluyveromyces lactis is a protein of outstanding biotechnological interest in the food industry and milk whey reutilization. However, due to its intracellular nature, its industrial production is limited by the high cost associated to extraction and downstream processing. The yeast-system is an attractive method for producing many heterologous proteins.

The arterial trunk of the thumb-index digital collaterals.

This is a study of the origin of the palmar collateral arteries of the thumb and radial side of the index finger. The different patterns of the main trunk, the first palmar interosseous artery, in the commissure are discussed, together with the relations of its branches with those of the superficial palmar arch and its relations with the accessory fasciculi of the adductor pollicis and first dorsal interosseous muscles.
