Ethanolic extracts from dried leaves of sage (Salvia officinalis) showed inhibition of [35S]tertiary-butylbicyclophosphorothionate ([35S]TBPS) binding to rat brain membranes in vitro. This ligand is considered to bind to the chloride channel of the GABA/benzodiazepine receptor complex in brain tissue. Substances having inhibitory activity were purified and their chemical structure identified as th
The serial Color Word Test, which is a semi-experimental way to differentiate adaptive behavior in stressful situations, was administered at baseline to men participating in the prospective cohort study "Men born in 1914". During follow-up, from 1982-1983 until December 31, 1996, 133 men experienced a myocardial infarction. Four patterns of adaptive behavior in 2 separate dimensions, the Variabili
Local signs and symptoms were evaluated in 187 consecutively presenting diabetic patients undergoing amputation for foot ulcers. From admission until final outcome the patients were treated by the same multidisciplinary team both as in- and out-patients. At the time of amputation, the types of lesions were superficial/deep ulcer (n 17), ulcer with deep infection, but without gangrene (n 40), and g
A theoretical model is established for diffusion of different types of ions in pore solution of concrete and the coupling to moisture flow and moisture content. Mass exchanges between ions in pore solution and solid hydration products in the concrete are also considered. The basic concepts behind the so-called mixture theory are used. The development of a mass balance principle for ions in pore so
Popular Abstract in Swedish Patienter med kroniskt obstruktiv lungsjukdom, KOL, har en försämrad lungfunktion och lider av bronkit och andnöd. Dessa symptom beror troligtvis på en ständigt pågående inflammation i lungan som dels leder till ökad slemproduktion och förträngning av luftrören, dels till emfysem dvs. nedbrytning av lungvävnaden vilket försämrar gasutbytet i lungan. Cigarrettrökning är Chronic obstructive pulmonary disease, COPD, is manifested by chronic airflow limitation due to inflammation and tissue destruction in the lungs. COPD is caused primarily by smoking and with increasing cigarette consumption in the world, the prevalence for COPD will most probably increase in the future. The chronic inflammation in the lungs of these patients is thought to drive the pathogenesis fo

Background: It has been shown previously that an anterior cruciate ligament injury may affect postural control, measured by balance in single-limb stance. To our knowledge, no studies have reported the influence of measures of impairment on postural control after such an injury. Purpose: To assess the influence of knee laxity, proprioception, and muscle strength on balance in single-limb stance an
The flux of ultrafiltration membranes may be severely reduced when treating low-molecular-weight hydrophobic solutes even though the cut-off of the membrane is orders of magnitudes greater than the size of the solute molecules. In this investigation, the flux reduction was correlated to the membrane pore size using octanoic acid as a model substance. As a comparison, the pore size was also determi
To increase our knowledge about mating-system evolution, we need to understand the relationship between specific floral traits and mating system. Species of Collinsia (Plantaginaceae) vary extensively in mating system; this variation is associated with variation in floral morphology and development and with the timing of self-pollination. Counterintuitively, large-flowered, more outcrossing specie
BACKGROUND: The gold standard to reconstruct a nerve defect is a conventional autologous nerve graft. There may be a lack of such grafts in severe nerve injuries. Alternatives to autologous nerve grafts are needed. METHODS: We have developed a technique where mainly Schwann cells are acutely dissociated from the ends of the severed nerve trunk after nerve injury. The technique does not require lon
To study whether antibodies to glutamic acid decarboxylase (GADab) are associated with subclinical beta-cell damage and impaired insulin secretion, we screened 441 nondiabetic patients with autoimmune thyroiditis (AT) for GADab, and 15 (3.4%) were found positive. Antibodies to IA-2 were found in two GADab+ and one GADab- patients. We matched 11 GADab+ and 13 GADab- AT patients who were euthyroid o
Malignant brain tumors present a major therapeutic challenge because no selective or efficient treatment is available. Here, we demonstrate that intratumoral administration of human α-lactalbumin made lethal to tumor cells (HAMLET) prolongs survival in a human glioblastoma (GBM) xenograft model, by selective induction of tumor cell apoptosis. HAMLET is a protein-lipid complex that is formed from α
Requirements Engineering and Testing are considered inseparable and together enable successful projects. One could make a statement that serious negligence of any of the two will bring catastrophic consequences for the project, delays, failures and unhappy customers. Thus, alignment and cooperation between the two are not only recommended but highly required for contemporary complex software and s
In this paper, multiple-input multiple-output (MIMO) channel measurements in an outdoor micro-cell environment are used to study the effect of base-station (BS) inter-element spacing on multi-user MIMO signal separation. Users with two dual-polarized patch antennas at the mobile station (MS), and four equally-spaced dual-polarized patch antennas at the BS are considered. At the BS, the inter-eleme
Although the clinical manifestations of atherosclerotic CHD occur in adult life, the preclinical phase begins long before, seemingly already in childhood. There is supportive evidence from both epidemiological studies and animal experiments that infections could contribute to the pathogenesis of arterial disease, including atherosclerosis. It has been hypothesised that damage to the vascular endot
Popular Abstract in Swedish Kalcium är inblandat i många viktiga processer i kroppen. Kalciumbindande proteiner är viktiga i detta sammanhang. Det finns ofta en vattenmolekyl med på bindningsstället i proteinet och vi har studerat hur den påverkar bindningsegenskaperna. Kalcium är inblandat i många viktiga processer i kroppen. Kalciumbindande proteiner är viktiga i detta sammanhang. Jag har studeUsing optical spectroscopy, nuclear magnetic resonance (NMR), and differential scanning Calorimetry (DSC), I have studied two different calcium binding proteins that can form kinetically trapped altered states. Calcium is very important in numerous biological processes such as blood coagulation, signal transduction, muscle contraction and bone formation. Calcium binding to proteins regulates these
