Acute acalculous cholecystitis (AC) is an inflammatory process of the gallbladder, often caused by other severe diseases. The etiology is multifactorial, but the pathogenesis is in all cases a reduction in the gallbladder's emptying capacity. The mortality of AC reaches 85% without treatment. This fact makes it important to consider AC as a possible complication to major surgery, multi-trauma, and

A new signal processing method for the detection of cyclic variations in atrial fibrillation frequency is presented. The objective was to investigate whether or not respiration, through the autonomic nervous system, modulates the fibrillation frequency in patients with permanent atrial fibrillation. A group of eight patients with permanent atrial fibrillation, atrioventricular block III and a perm

The effects of energy conservation and saturation are studied in the coordinate space dipole formulation for QCD cascades. Preliminary results for dipole-dipole and dipole-nucleus scattering are presented. Very large effects are obtained from energy conservation, corresponding to a factor similar to 10 in the cross section and similar to 3 in lambda(eff). Some results on the gluon fusion process g

The molecular mobility in a hexagonal DNA-cationic surfactant complex is studied using H-1 and C-13 nuclear magnetic resonance spectroscopy. The charge-compensated complex can swell in water up to a content of approximately seven water molecules per charge. The NMR measurements show that in the dry state the alkyl chains of the surfactant have the properties of a disordered solid with internal mot

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
