The effect of betamethasone on choroid plexus transport and CSF formation in rabbits was studied. Following 5 days of daily treatment with betamethasone the CSF production rate was reduced by 43% as measured by ventriculo-cisternal perfusion with radioactive inulin. Accordingly, the Na(+)-K(+)-ATPase activity and the transport capacity in the choroid plexus, measured in terms of choline (10(-5) M)

Analytical formulas for the estimation of pressure and shear stresses due to friction on bent surfaces during the handling of fibers in the manufacture of industrial textiles and composites have been derived using the drive belt formula and Hertz contact stress relations. Experimentally measured at low speed, the forces and coefficients of friction give shear stresses in the same range as for the
In real-time systems potentially unbounded loops and lazy (late) evaluation are often avoided in order to improve predictability. This paper will show that a commonly suggested way to implement semaphores can lead to unnecessary blocking of high-priority tasks. It also presents a scheme with lazy evaluation and (potentially) unbounded loops that gives less blocking of high-priority tasks.
This report summarizes experiences and conclusions from a trip to University College Swansea, Swansea, Wales, the Central Electric Generation Board (CEGB), Barnwood, Gloucester, England and Marconi Instruments Limited, Scotland. The aim of the trip was to exchange information and discuss various issues incomputer aided control engineering.
This population-based register study examined if factors during the fetal and neonatal period influence the risk for the child to develop bronchial asthma (asthma). From the Swedish Hospital Discharge Register we identified children, born between 1987 and 1999, who had been hospitalized for asthma up to 2001. Thus, the outcome measure contains only hospitalized cases, not all children with asthma.
The authors performed a retrospective study of 50 patients with endoscopically diagnosed duodenitis who had undergone double-contrast upper gastrointestinal (GI) examinations. Duodenitis was diagnosed on the original radiographic reports in six of 37 patients (16%) with mild-to-moderate duodenitis, five of 13 patients (38%) with severe duodenitis, and 11 of 50 patients (22%) with all grades of duo
A discrepancy in the ABO blood groups between a newborn child and her parents was identified. Serological and DNA investigative techniques were performed. A weak variant of B (B-w) was detected on the erythrocytes of the child, her grandmother and great-uncle. Adsorption-elution studies showed that their erythrocytes adsorb and yield anti-B on elution. The B-w antigenic strength of the A(1)B(w) ce
Popular Abstract in Swedish Parkinsons sjukdom (PS) karaktäriseras av långsam celldöd i hjärnan och gradvis uppträder minskad rörlighet och muskelstelhet som mest framträdande symptom. PS drabbar ungefär 0.1% av befolkningen, och inträder oftast i femtio- till sextioårsåldern. Varför sjukdomen uppkommer är till stor del okänt, men man vet att de dopamin producerande cellerna i mitthjärnan (särskilParkinson's disease (PD) is a common neurodegenerative disorder characterized by motor deficits. Levodopa treatment provides marked symptomatic relief. However, within 5-10 years after the start of Levodopa treatment, most PD patients display a gradual loss of drug efficacy. Importantly, the neuropathology of PD is dominated by a marked loss of dopaminergic neurons located in the substantia nigra.
To determine the incidence of anterior cruciate ligament (ACL) injuries in the general population; the pathology associated with a knee sprain verified by magnetic resonance imaging (MRI); and the agreement between clinical findings and MRI.Materials and methods: Inclusion criterion was an acute rotational trauma to the knee associated with effusion. One hundred and fifty-nine consecutive patients
High-spin states in Sb-106 have been investigated in the Fe-54(Ni-58, 1α 1p1n) reaction by in-beam γ-spectroscopic methods using the EUROBALL detector array equipped with charged particle and neutron detectors. On the basis of measured γγ-coincidence relations, angular distributions, and linear polarization ratios a significantly extended level scheme has been constructed up to spin and parity I-π
Parasympathetic denervation of the urinary bladder results in supersensitivity to muscarinic agonists and in bladder hypertrophy. In the present study, the effects of denervation on the muscarinic receptors in the rat bladder were investigated, using a receptor binding technique with (-)3H-QNB as radioligand. The density of muscarinic receptors was increased in denervated, hypertrophied bladders b
Triglycerides in the beta-cell may be important for stimulus-secretion coupling, through provision of a lipid-derived signal, and for pathogenetic events in NIDDM, where lipids may adversely affect beta-cell function. In adipose tissues, hormone-sensitive lipase (HSL) is rate-limiting in triglyceride hydrolysis. Here, we investigated whether this enzyme is also expressed and active in beta-cells.
