Protein inhibitors of proteolytic enzymes regulate proteolysis and prevent the pathological effects of excess endogenous or exogenous proteases. Cysteine proteases are a large family of enzymes found throughout the plant and animal kingdoms. Disturbance of the equilibrium between cysteine proteases and natural inhibitors is a key event in the pathogenesis of cancer, rheumatoid arthritis, osteoporo
HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a tumoricidal complex consisting of partially unfolded protein and fatty acid, and was first identified in casein fractions of human breast milk. The complex can be produced from its pure components through a modified chromatographic procedure where pre-applied oleic acid binds with partially-unfolded alpha-lactalbumin on the stationar
Group G streptococcus (GGS) is a human pathogen of emerging clinical significance. It causes skin and soft tissue infections, occasionally resulting in life-threatening conditions such as sepsis and necrotizing fasciitis. We recently identified FOG, a novel surface protein of GGS with fibrinogen binding and immune evasion properties. Here we investigated the role of FOG in streptococcal primary ad
Background: When reporting stroke survival and prognostic factors with a possible effect on outcome, the starting point for the observation of a clinical cohort usually is the onset of stroke or the acute admission of a patient. Thus, acute and early mortality inflict prognosis on long-term outcome. In order to give a more robust analysis of long-term survival after the acute period we chose to st
Elongation factor Ts (EF-Ts) is the guanine-nucleotide exchange factor of elongation factor Tu (EF-Tu), which promotes the binding of aminoacyl-tRNA to the mRNA-programmed ribosome in prokaryotes. The EF-Tu.EF-Ts complex, one of the EF-Tu complexes during protein synthesis, is also a component of RNA-dependent RNA polymerases like the polymerase from coliphage Qbeta. The present study shows that t
Pheromone-based monitoring is a promising new method for assessing the conservation status of many threatened insect species. We examined the versatility and usefulness of pheromone-based monitoring by integrating a pheromone–kairomone trapping system and pitfall trapping system in the monitoring of two saproxylic beetles, the hermit beetle Osmoderma eremita (Coleoptera: Scarabaeidae) and its pred
Various ecosystems, including shallow lakes, are suggested to possess alternative stable state dynamics. The response of such systems to environmental change is non-linear and not fully reversible, which calls for identification of feedback mechanisms and subtle changes connected to structural stability. Here, we used a 25-year data series on water chemistry to make inferences on processes prior t
We describe 4 patients who all simultaneously developed a sudden total or partial unilateral sensorineural hearing loss and an unusual acute peripheral vestibulopathy in the same ear characterized by posterior semicircular canal benign paroxysmal positional vertigo with intact lateral semicircular canal function. Two patients also had ipsilateral loss of otolith function. The vertigo resolved in a
Objective - Inflammation plays an important role in atherosclerosis. One of the most potent pro-inflammatory cytokines is tumor necrosis factor-alpha (TNF-alpha), a cytokine identified to have a pathogenic role in chronic inflammatory diseases such as rheumatoid arthritis ( RA). The aim of the study was to evaluate the importance of TNF-alpha in atherogenesis. Methods and Results - Mice deficient
Purpose. The purpose of this study was to test the General Motor Function Assessment Scale (GMF) for content and criterion validity in geriatric home-rehabilitation. Furthermore, the GMF was analysed with respect to sensitivity, distribution, and for floor and ceiling effects. Method. Content validity was explored by questionnaires circulated to ten experts in the field of geriatrics. Three assess
By emphasising the involvement of elderly people in a project applying a mixed-method approach, the overriding objective of this study was to identify and prioritise concrete measures aimed at increasing accessibility and safety in the outdoor pedestrian environment within a residential area of a Swedish town. Measures generally given priority were: the separation of pedestrians/cyclists, lower sp
An increasing demand for both formal and informal care is likely to result from the ongoing demographic transition at the same time as there is a further move away from the traditional domestic division of labour. Public policy-making that aims at increasing the supply of informal care necessitates knowledge about the relative importance of various incentives for individual care providers. This pa
Halomonas boliviensis sp. nov. is proposed for two moderately halophilic, psychrophilic, alkalitolerant bacteria, LC1(T) (=DSM 15516(T)=ATCC BAA-759(T)) and LC2 (=DSM 15517=ATCC BAA-760), both of which were isolated from a soil sample around the lake Laguna Colorada, located at 4300 m above sea level in the south-west region of Bolivia. The bacteria are aerobic, motile, Gram-negative rods that pro
Eyes of the hoverfly Eristalis tenax are sexually dimorphic such that males have a fronto-dorsal region of large facets. In contrast to other large flies in which large facets are associated with a decreased interommatidial angle to form a dorsal 'acute zone' of increased spatial resolution, we show that a dorsal region of large facets in males appears to form a 'bright zone' of increased light ca
We have previously raised two monoclonal antibodies (7B1, 14F11) recognizing the high-affinity leukotriene B4 receptor, BLT1. They were presently used to determine receptor surface expression in the hematopoietic system. In peripheral blood, BLT1 was primarily recognized in granulocytes, monocytes and, to a lower extent, in certain lymphocytes except the CD4 subpopulation. The expression pattern w
Two separate citrate synthases from the extremely thermophilic bacterium Rhodothermus marinus have been identified and purified. One of the enzymes is a hexameric protein and is the first thermostable, hexameric citrate synthase to be isolated. The other is a dimeric enzyme, which is also thermostable but possesses both citrate synthase and 2-methyl citrate synthase activities. 2-Methyl citrate sy
GaSb/GaAs quantum dot systems are fabricated using MBE under various growth modes. The as-grown samples are studied with in situ synchrotron radiation XPS covering the As 3d, Sb 4d and Ga 3d core levels and the valence band region. The XPS spectra show dramatic changes with the growth modes, reflecting changes in the local electronic structure and chemical environments of the surface and interface
Adenoviral vector-mediated transfer of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can be a powerful approach to lung cancer therapy. However, the efficiency of adenoviral vector gene transfer and the sensitivity to TRAIL-induced apoptosis in the context of adenoviral vector gene transfer have yet to be characterized in primary lung cancers. In this study, we investigated the e
The molecular pathways regulating lymphoid priming, fate, and development of multipotent bone marrow (BM) stem/ progenitor cells that continuously replace thymic progenitors remain largely unknown. Herein, we show that fms-like tyrosine kinase 3 (Flt3) figand (FI)-deficient mice have distinct reductions in the earliest thymic progenitors in fetal, postnatal, and adult thymus. A critical role of FL
Purpose: To assess the additional value of subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) for localization of the epileptogenic zone in patients with drug-resistant epilepsy scheduled for invasive video-EEG (VEEG) before epilepsy surgery by a descriptive study from clinical practice. Methods: Forty-nine consecutive epilepsy patients between Januar
