Nonfatal stroke, cardiac disease, and diabetes mellitus in hypopituitary patients on hormone replacement including growth hormone

Context: The impact of long-term GH replacement on cerebrovascular and cardiovascular diseases and diabetes mellitus in hypopituitary patients is unknown. Objective: The incidence of nonfatal stroke and cardiac events, and prevalence of type 2 diabetes mellitus ( T2D) and cardioprotective medication were compared between cohorts of GH-deficient (GHD) patients and population controls. Design and Pa

Limiter-free third order logarithmic reconstruction

A third order conservative reconstruction, in the context of finite volume schemes for hyperbolic conservation laws, is constructed based on logarithmic functions. This logarithmic method reconstructs without the use of a limiter, any preprocessing of input data, special treatments for local extrema, or shock solutions. Also the method is local in the sense that data from only the nearest neighbor

Action spectra for enhancement of ultraweak luminescence by UV radiation (270–340 nm) in leaves of Brassica napus

Fluence-response relationships for the enhancement of ultraweak luminescence by UV radiation were determined in leaves of Brassica napus L. (cv. Ceres) when either the adaxial or abaxial leaf surface was exposed to monochromatic radiation (270–340 nm). Action spectra for both leaf surfaces were constructed from the fluence-response curves at the fluence required to obtain a doubling of the ultrawe

Optimisation of a dosing strategy for an HC-SCR diesel exhaust after-treatment system

Several principal aspects and components of an advanced catalytic exhaust after-treatment system for NO, reduction on a heavy-duty diesel truck engine have been systematically examined and evaluated. The after-treatment system consists of de-NO, catalysts, injection of a reducing agent (diesel fuel), and computer programs to model the engine and catalysts in real time. These models are combined wi

Romanfigurer ger liv åt tentans patientfall

I Lund avslutas läkarutbildningens tionde termin med en MEQ-skrivning (Modified Essay Questions). Höstterminen 2002 hämtade vi bakgrundsmiljö och persongalleri till frågornas fallbeskrivningar från ett skönlitterärt verk. Initiativet föll väl ut hos studenterna – de tyckte att boken var bra och att upplägget var utmärkt. Också författaren var nöjd – efter vår »medikalisering« lärde han känna sina

Inhibition of calcium entry preserves contractility of arterial smooth muscle in culture

The addition of the growth stimulator fetal calf serum (FCS, 10%) to rings of rat tail artery causes an increase in [Ca2+]i, accompanied by contraction. This response was inhibited by the calcium entry blocker verapamil (1 microM). To investigate the effect of Ca2+ entry blockade on growth and contractility, rings of rat tail artery were cultured for 4 days in medium with or without FCS and then m

Global gene expression analysis in a mouse model for Norrie disease: late involvement of photoreceptor cells

PURPOSE: Mutations in the NDP gene give rise to a variety of eye diseases, including classic Norrie disease (ND), X-linked exudative vitreoretinopathy (EVRX), retinal telangiectasis (Coats disease), and advanced retinopathy of prematurity (ROP). The gene product is a cystine-knot-containing extracellular signaling molecule of unknown function. In the current study, gene expression was determined i

Neuropeptide expression in the human trigeminal nucleus caudalis and in the cervical spinal cord C1 and C2.

In migraine and other primary headaches there is a strong vascular component. Besides the trigeminovascular components some of the associated symptoms point to the involvement of brain stem regions. The central limb of the trigeminal vascular pathway is its projection to the trigeminal nucleus caudalis (TNC) and to the C1-C2 levels of the spinal cord. The aim of the present study was to demonstrat

Dietary patterns and survival of older Europeans: The EPIC-Elderly study (European Prospective Investigation into Cancer and Nutrition)

Objective: To investigate the association of a posteriori dietary patterns with overall survival of older Europeans. Design and setting: This is a multi-centre cohort study. Cox regression analysis was used to investigate the association of the prevailing, a posteriori-derived, plant-based dietary pattern with all-cause mortality in a population of subjects who were 60 years or older at recruitmen

Exploring the formation of carbon-based molecules, clusters and particles by in situ detection of scattered X-ray radiation

The angular pattern of scattered X-ray radiation (1.2-2.5 Angstrom) from flames has been measured and analyzed. The results are compared with calculations on different molecules, such as polyaromatic hydrocarbons, fullerenes and other spherical structures. Measurements have also been performed on soot condensed on a cooling plate inserted inside a flame. Size- and shape-dependent structures are ob

Wildfires in NW Patagonia: long-term effects on a Nothofagus forest soil

In NW Patagonia, Argentina, poor regeneration after fires of Nothofagus pumilio (Poepp. and Endl.) Krasser forests located in drier environments has been attributed to probable edaphic changes. We studied the long-term effects of wildfire on the mineralogical, physical, chemical and biological properties of a soil developed from volcanic-ashes under N. pumilio forests. Soils from six small patches

A determination of the centre-of-mass energy at LEP2 using radiative two-fermion events

Using e(+)e(-) -> mu(+)mu(-)(gamma) and e(+)e(-) -> q (q) over bar(gamma) events radiative to the Z pole, DELPHI has determined the centre-of-mass energy, root s, using energy and momentum constraint methods. The results are expressed as deviations from the nominal LEP centre-of-mass energy, measured using other techniques. The results are found to be compatible with the LEP Energy Working Group e

Activated protein C-protein C inhibitor complex: a new biological marker for aortic aneurysms.

Objective: The concentration of the complex between activated protein C (APC) and protein C inhibitor (PCI) is a measure of thrombin generation. We studied whether it can provide information useful for the diagnosis and treatment of arterial vascular disease. Methods: Blood was obtained from 429 vascular patients admitted consecutively during September 2004 to March 2005. The APC-PCI complex was m
