At present, when economy and environment receive high priority, the ideal anaesthesia system with inhalation anaesthetics is a closed circle system in which only the gases which the patient consumes or produces are replaced or eliminated. Low-flow (LF) anaesthesia in which the fresh gas flow which is employed in a closed system, provides a stable system compares with closed anaesthesia systems. Co
Nitro blue tetrazolium (NBT) is an artificial electron acceptor which has been suggested to be a useful tool in studies of free radicals. To establish whether NBT could be useful in morphological demonstration of free radicals in the retina, the staining pattern was examined in normal rat retina and after incubation with the free radical scavenger superoxide dismutase or with inhibitors of free ra
Abstract not available
Nitro blue tetrazolium (NBT) staining in normal rat retina was previously found to be affected by inhibition of free radical-related enzyme systems, indicating that NBT might be useful as a marker of free radicals. The aim of the present study was to investigate NBT staining in rat retina in vitamin E deficiency and after blue light exposure, and also to measure hydrogen peroxide (H2O2) production
On-going research aims at answering the question, which satiety signal is the most potent or which combination of satiety signals is the most potent to stop eating. There is also an aim at finding certain food items or food additives that could be used to specifically reduce food intake therapeutically. Therapeutic attempts to normalize body weight and glycaemia with single agents alone have gener
We show that twisting of an infinite straight three-dimensional tube with non-circular cross-section gives rise to a Hardy-type inequality for the associated Dirichlet Laplacian. As an application we prove certain stability of the spectrum of the Dirichlet Laplacian in locally and mildly bent tubes. Namely, it is known that any local bending, no matter how small, generates eigenvalues below the es
BACKGROUND: Recent studies have suggested that reactive oxygen species may be involved in the development of diabetic retinopathy. METHODS: Nitro blue tetrazolium (NBT) staining, a marker of reductants which may be induced by free radicals such as superoxide, and catalase activity, as an indirect measure of hydrogen peroxide (H2O2) generation, were studied in the rat retina in three conditions kno
To achieve high thermal efficiencies, 30 percent and higher, for small gas turbines a recuperator is mandatory. As the recuperator represents 25–30 percent of the overall machine cost, efforts are now being focused on establishing new low-cost recuperator concepts for gas turbine engines. In this paper the cross corrugated (CC), also called chevron pattern, heat transfer surface is reviewed to ass
Postoperative morbidity after hysterectomy was studied prospectively in 229 consecutive patients in our departments. The incidence of alcohol abuse (> or = 60 gm of alcohol daily) and moderate drinking (between 25 and 60 gm of alcohol daily) was 6.5% for each. When compared with the moderate drinkers and the control group, the alcohol abusers developed significantly more complications (80% versus
In Sweden 1600 patients/year survive cardiac arrest (30-day survival). Post-resuscitation care is complex and aims to stabilize organ function with focus on preventing secondary brain injury. In 2021 The European Resuscitation Council (ERC) and European Society of Intensive Care Medicine (ESICM) published joint guidelines on post-resuscitation care. In this article the Swedish Resuscitation Counci
En åpen og opplyst offentlig samtale er en forutsetning for et velfungerende demokrati. Dette idealet fordrer at borgere i stor grad tolererer meningsmotstandere fremfor å utvikle fiendtlige holdninger til dem man er uenig med. En rekke studier fra USA har imidlertid vist at borgere i økende grad er fiendtlig innstilt til velgere de er politisk uenig med (Iyengar et al., 2019). Dette fenomenet er
