Is a nappy change stressful to neonates?

Objectives: Infants in neonatal intensive care (NICU infants) are often cared for in a stressful environment that includes potentially painful or stressful interventions. The aim was to investigate whether NICU infants have different pattern of stress and pain responses than healthy newborns when challenged by a non-painful everyday care routine. Methods: NICU infants born at 23-38 weeks gestation

Fruits of Capitalism, Modernisation of Chilean Agriculture 1950-2000

Popular Abstract in Swedish Det så kallade Chilenska ekonomiska undret under 1980- och 1990-talet är resultatet av en omfattande strukturförändring av den Chilenska ekonomin. I denna omvandling har jordbrukets modernisering och kapitalisering spelat en mycket viktig roll.Huvudfåran i den akademiska debatten har hittills huvudsakligen förklarat omvandlingen genom tillämpning av olika policy instrumThe so-called Chilean economic miracle during the 1980s and 1990s connotes not only high-speed economic growth but also a profound structural transformation of the Chilean economy. Most previous research ascribes growth and transformation to the liberalisation of markets and other neo-liberal policy instruments introduced after 1974. Policies, before as well as after 1974, have indeed been importa

Localization of the initial fibrillatory cycle in patients with paroxysmal atrial fibrillation

BACKGROUND: Recent reports suggest the presence of conduction delay in the posterior septal region during sinus rhythm in patients with lone paroxysmal atrial fibrillation (AF). OBJECTIVE: To explore the location of intra-atrial conduction delay associated with initiation of AF. DESIGN: In 8 lone AF patients (51 +/- 10 years), 20 AF paroxysms were induced during electrophysiological examination. B

Nitric oxide relaxes rat tail artery smooth muscle by cyclic GMP-independent decrease in calcium sensitivity of myofilaments

The effects of authentic nitric oxide (NO, 10(-6) M) and NO-donors such as sodium nitroprusside (SNP, 10(-5) M) and glyceryl trinitrate (GTN, 10(-4) M) on contractile force and free intracellular calcium level ([Ca2+],) were studied on precontracted with high potassium chloride (KCI, 70 mM) isolated rings of rat tail artery. The sensitivity of contractile myofilaments to Ca2+ was measured using ch

Rapid caspase-dependent cell death in cultured human breast cancer cells induced by the polyamine analogue N-1,N-11-diethylnorspermine

The spen-nine analogue N-1,N-11-diethylnorspermine (DENSPM) efficiently depletes the cellular pools of putrescine, spermidine and spermine by down-regulating the activity of the polyamine biosynthetic enzymes and up-regulating the activity of the catabolic enzyme spermidine/spermine N-1-acetyltransferase (SSAT). In the breast cancer cell line L56Br-Cl. treatment with 10 muM DENSPM induced SSAT act

The influence of non-dissipative quantities in kinematic hardening plasticity

A kinematic hardening plasticity model valid for finite strains is presented. The model is based on the well-known multiplicative split of the deformation gradient into an elastic and a plastic part. The basic ingredient in the formulation is the introduction of locally defined configurations center configurations- which are associated with deformation gradients that are used to characterize the k

The arthropod community of Scots pine (Pinus sylvestris L.) canopies in Norway

We summarise the findings of arthropods collected by fogging the canopy of 24 pine trees in two sites in Eastern and Western Norway. From the samples, taken in 1998 and in 1999, almost 30,000 specimens were determined to 512 species, with Diptera being most species rich (210 species), followed by Coleoptera (76 species) and Araneae (49 species). Of the 96 new species records, nine were new to scie

Tissue damage in heated carrot slices. Comparing mild hot water blanching and infrared heating

Mild heat treatment of carrot slices as a pre-treatment for frozen storage was accomplished by exposure of slices to radiant heat to maximise thermal exposure of the cells at the surface while preserving the integrity of cells within the slices. Cell damage as a consequence of this treatment on texture was evaluated. Carrot slices treated for 7 s with radiant energy in the far-infrared region from

Conflict Prevention from a Nordic Perspective: Putting Prevention into Practice

Since conflict prevention is a visionary strategy it has beer difficult to put it into practice. This article explores conflict prevention in practice as well as in theory. There have been several attempts by the international community to take a proactive rather than a reactive approach to conflict management. One case often held up as a model for post Cold War prevention is the preventive missio
