Inadequate evaluation and management of suspected ­infections after TKA surgery in Lithuania : a retrospective study of 2,769 patients with 2-year follow-up

Background and purpose — The evidence-based algorithms for treatment of periprosthetic joint infection (PJI) recommend surgical intervention in combination with the use of systemic antibiotics. However, still it is not unusual to treat total knee arthroplasty (TKA) patients with suspected infection using only antibiotics. We investigated treatment pathways for TKA patients with suspected infection

Emerging 2D-ferromagnetism and strong spin-orbit coupling at the surface of valence-fluctuating EuIr2Si2

The development of materials that are non-magnetic in the bulk but exhibit two-dimensional (2D) magnetism at the surface is at the core of spintronics applications. Here, we present the valence-fluctuating material EuIr2Si2, where in contrast to its non-magnetic bulk, the Si-terminated surface reveals controllable 2D ferromagnetism. Close to the surface the Eu ions prefer a magnetic divalent confi

Compensatory changes of in vivo acetylcholine and noradrenaline release in the hippocampus after partial deafferentation, as monitored by microdialysis

Lesions of the fimbria-fornix pathways are known to induce a partial cholinergic and noradrenergic denervation of the hippocampal formation, which is followed by a slow and protracted collateral sprouting by the spared afferents. Using the intracerebral microdialysis technique, compensatory changes in extracellular levels of acetylcholine (ACh) and noradrenaline (NA) have been monitored over time

Longitudinal growth of the distal fibula in children with slipped capital femoral epiphysis

Summary: The longitudinal growth rates of the distal fibula were measured, using a roentgen stereophotogrammetric method, in 32 children treated for slipped capital femoral epiphysis and compared with growth rates in a series of normal children. The growth rates in patients were similar to the growth rates in normal children, in both boys and girls. However, at the time of slippage, 13 patients ha

Toward Reliable Lipoprotein Particle Predictions from NMR Spectra of Human Blood : An Interlaboratory Ring Test

Lipoprotein profiling of human blood by 1H nuclear magnetic resonance (NMR) spectroscopy is a rapid and promising approach to monitor health and disease states in medicine and nutrition. However, lack of standardization of measurement protocols has prevented the use of NMR-based lipoprotein profiling in metastudies. In this study, a standardized NMR measurement protocol was applied in a ring test

In vivo acetylcholine release as measured by microdialysis is unaltered in the hippocampus of cognitively impaired aged rats with degenerative changes in the basal forebrain

Acetylcholine (ACh) release was studied in awake, freely moving animals using in vivo microdialysis in the hippocampus of young (3-month-old) and aged (24-month-old) female Sprague-Dawley rats. Two groups of aged rats were selected on basis of their spatial learning performance in the Morris water maze: non-impaired aged rats which performed as well as the young control animals, and impaired aged

Hymns to Unknown Heroines part III

Hymns to Unknown Heroines part III – Elna, 2015 Slide and sound installationHymns to Unknown Heroines, part III is the latest iteration of a multifaceted work. The starting point was an anonymous photographic archive from the 1920s that depicts a Scottish family over several years. Many of the photographs portray women engaged in recreational activities, portraying an undemanding lifestyle that ca

A new method to evaluate the thermal stability of lyophilized enzymes

The thermal inactivation of lyophilized chymotrypsin was studied at controlled water activities. At 60 °C the enzyme showed good stability except at aw 0.97, whereas at 75 °C considerable inactivation occured at most water activities. Increasing the amount of buffer on the preparation decreased the stability significantly. The optimal temperature of enzymatic activity was increased 14 °C, when the

The rat gastric phospholipids : Increased in ulcerated mucosa and decreased after healing

The composition and content of the gastric phospholipids were followed during development and healing of indometha-cin-induced chronic, antral ulcers in rats. The individual phospholipids were identified by thin-layer chromatography and quantitatively estimated by spectrophotometric analysis of phosphate. No changes were found in phospholipid composition and content after a 24-hour fast or during

Stabilization of Adsorbed Enzymes Used as Biocatalysts in Organic Solvents

Enzymes immobilized by deposition onto a solid support at low enzyme loadings were shown to be stabilized by additives, such as proteins and PEG. The additive protects the enzyme from deactivation during immobilization. The amount of additive required to obtain full stabilization was dependent on the type of support material used and corresponded approximately to a monolayer coverage of the additi
