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

Purpose Young adults (18–24 years) frequently report poorer health care access and experience than older adults. We aimed to investigate how differences between young and older adults vary across 11 high-income countries. Methods A total of 20,045 participants from 11 high-income countries (i.e., Australia, Canada, France, Germany, the Netherlands, New Zealand, Norway, Sweden, Switzerland, United

To determine factors associated with the antipsychotic (AP) prescription for people with dementia (PwD) recently admitted to institutional long-term care facilities (LTCFs) and to ascertain differences in the use of this medication in 8 European countries.

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

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

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
