We previously identified a positive transcriptional element identical to human Ha-ras response element ( HRE) within the promoter of the rat Ha-ras gene. We further identified CArG binding factor A ( CBF-A), a member of heterogeneous nuclear ribonuclear protein ( hnRNP) gene family, as a trans-acting factor that binds the HRE sequence with high affinity in rat mammary carcinoma cells. To determine

Eleven species of common fungi from compost were analysed for their content of ergosterol and phospholipid fatty acids (PLFAs) after growth on agar media. Mean content of ergosterol was 3.1 mg g(-1) dw of fungal mycelium (range 1-24 mg g(-1) dw). Total amount of PLFAs varied between 2.6 and 43.5 mumol g(-1) dw of fungi (mean 14.9 mumol g(-1) dw). The most common PLFAs were 16:0,18:2omega6,9 and 18

Three building components exposed to natural climate were studied: a dynamic insulation in the ceiling of a house, an outer wall and one window in the same wall. The term dynamic insulation implies that part of the inlet or exhaust air passes through the insulation of a house. A house with dynamic insulation was continuously measured for approximately a year and a half. The performance of the dyna

The effects of a stretch-release cycle (25 of the resting muscle fibre length, Lo) on both tension and [Ca2+i in small, unstimulated, intact muscle fibre bundles isolated from adult and neonatal rats were investigated at 20 C. The results show that the effects of the length change depended on the age of the rats. Thus, the length change produced three effects in the neonatal rat muscle fibre bundl

Redox dependent protein phosphorylation in chloroplast thylakoids regulates distribution of excitation energy between the two photosystems of photosynthesis, PS I and PS II. Several thylakoid phosphoproteins are known to be phosphorylated on N-terminal threonine residues exposed to the chloroplast stroma. Phosphorylation of light harvesting complex II (LHC II) on Thr-6 is thought to account for re

The first part of the investigation is related to the heat transfer and fluid flow problem inside ribbed ducts with a square cross section. The typical applications of this problem are in the cooling of gas turbine blades and guiding vanes. The second part is related to application of intercoolers in gas turbine systems. The intercooling is performed via intercoolers that usually are water-air hea

The cerebrovascular lesions of severe chronic hypertension were studied by light microscopy in perfusion-fixed, subserially sectioned brains from stroke-prone spontaneously hypertensive rats (SHRSP). The leakage and spread of plasma proteins were visualized by immunohistochemical detection of extravasated fibrinogen and by using an exogenous marker (Evans blue injected i.v.) for blood-brain barrie
