Identification of acidic amino acid residues in the protein kinase C alpha V5 domain that contribute to its insensitivity to diacylglycerol

The protein kinase C (PKC) isoforms are maintained in an inactive and closed conformation by intramolecular interactions. Upon activation these are disrupted by activators, binding proteins and cellular membrane. We have seen that autophosphorylation of two sites in the C-terminal V5 domain is crucial to keep PKC alpha insensitive to the activator diacylglycerol, which presumably is caused by a ma

Effects of the introduced ectoparasite Philornis downsi on haemoglobin level and nestling survival in Darwin's Small Ground Finch (Geospiza fuliginosa)

The physiological impacts and fitness costs of parasitism by an introduced ectoparasitic fly, Philornis downsi (Muscidae), were studied in nestlings of Darwin's Small Ground Finch, Geospiza fuliginosa (Geospizinae), on the Galápagos Archipelago. Whole blood haemoglobin (Hb) concentration was used to measure host response to ectoparasitism due to its high repeatability and validity, as well as for

The Stribeck memorial lecture

Stribeck's publications Wugellager fur beliebige Belastungen' and 'Die wesentlichen Eigenschaften der Gleit- und Rollenlager' were remarkable for their time. Many of the findings were revolutionary and are still considered quite modem. The method used by Stribeck to calculate load distribution between the balls within a ball bearing is still used today, otherwise, a full finite element analysis wo

Disposable polymeric high-density nanovial arrays for matrix assisted laser desorption/ionization-time of flight-mass spectrometry: I. Microstructure development and manufacturing

In order to meet the expected enormous demand for mass spectrometry (MS)through-, put as a result of the current efforts to completely map the human proteome, this paper presents a new concept for low-cost high-throughput protein identification by matrix assisted laser desorption/ionization-time of flight-(MALDI-TOF)-MS peptide mapping using disposable polymeric high-density nanovial MALDI target

A distinct Toll-like receptor repertoire in human tonsillar B cells, directly activated by PamCSK, R-837 and CpG-2006 stimulation.

Toll-like receptors (TLRs) recognize specific pathogen-associated molecular patterns (PAMPs), which subsequently trigger innate immunity. Recent data also suggest a role for TLRs in the direct activation of adaptive immune cells. In the present study, the expression and function of TLR1-TLR10 were characterized in purified human tonsillar B cells, focusing on differences among CD19(+) CD38(-) CD27

Risk of Myocardial Infarction and Stroke in Smokers Is Related to Plasma Levels of Inflammation-Sensitive Proteins.

Background— The extent to which differences in cardiovascular risk between smokers with similar daily tobacco consumption may be related to plasma levels of inflammation-sensitive proteins (ISP) and whether these proteins are associated with levels of carboxyhemoglobin (COHb%) have not been clarified. Methods and Results— In a population-based cohort of 1489 never smokers, 1685 former smokers, an

Development and validation of LC-MS/MS method for the determination of cyproheptadine in several pharmaceutical syrup formulations.

A rapid and sensitive liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method was developed and validated for the qualitative and quantitative assay of cyproheptadine (CP) in pharmaceutical samples. Diphenylpyraline hydrochloride (DPP) was used as an internal standard (IS). Two multiple reaction-monitoring (MRM) transitions for each analyte were observed: 288.1/96.1 and 288.1/191.2 for

Migration of the Charnley stem in rheumatoid arthritis and osteoarthritis. A roentgen stereophotogrammetric study

Migration of 65 Charnley stems implanted with modern cementing techniques was studied by roentgen stereophotogrammetry. There were 25 patients with rheumatoid arthritis (RA) and 40 with osteoarthritis (OA) followed up for two years. In 43 cases a bone sample for histomorphometric analysis was obtained from the femur during the operation. In 22 cases the mean subsidence of the prosthetic head was 0

Preserving bone health in patients with hormone-sensitive prostate cancer: the role of bisphosphonates

Men with prostate cancer initiating androgen-deprivation therapy (ADT) may have multiple factors that threaten their skeletal health, including increased fracture risk from bone loss during ADT and the propensity to develop bone metastases, which may lead to skeletal-related events (SREs). Bisphosphonates have utility in oncology for patients with bone metastases to prevent bone loss during hormon

Guest Editorial: Introduction to the Creative Class in European City Regions

This special issue presents the results of a European research project on the creative class in European city regions. In this introduction, the need for contextualizing the approach is underlined, taking into account the differences between the United States, where Richard Florida's ideas were developed, and Europe. In modifying the approach to suit European conditions, varieties of capitalism an

Direct hospital resource utilization and costs of treating patients with multiple myeloma in Southwest Sweden: a 5-year retrospective analysis.

BACKGROUND: Approximately 570 patients are diagnosed with multiple myeloma (MM) in Sweden each year. Few studies have estimated the cost of treatment for these patients. OBJECTIVE: The purpose of this study was to retrospectively investigate the direct hospital resource utilization and costs associated with the treatment of patients with MM in southwest Sweden. METHODS: Patients aged > or =18 year

Emergency voltage control using search and predictive control

This paper presents a method of optimal coordination of load shedding, capacitor switching and tap changer operation using a dynamic system model in order to preserve or retain long-term voltage stability. The method is based on model predictive control and tree search. A model of the controlled system, including the network and load dynamics, is used to predict the future system behaviour based o

The impact of an educational intervention for elderly care nurses on care recipients’ and family relatives’ ratings of quality of care: A prospective, controlled intervention study

Background Low competence levels among nursing staff have been associated with lower quality of elderly care. However, interventions aimed at improving nursing staff competence have not always been evaluated for their possible impact on the quality of elderly care. An educational intervention in the form of a workplace “toolbox” was shown to have positive effects on nursing staff competence and wo

Rapid method of determining factors limiting bacterial growth in soil

A technique to determine which nutrients limit bacterial growth in soil was developed. The method was based on measuring the thymidine incorporation rate of bacteria after the addition of C, N, and P in different combinations to soil samples. First, the thymidine incorporation method was tested in two different soils: an agricultural soil and a forest humus soil. Carbon (as glucose) was found to b

Effect of Surfactant on Structural and Thermodynamic Properties of Aqueous Solutions of Hydrophobically Modified Ethyl(hydroxyethyl)cellulose

Solution properties of ethyl(hydroxyethyl)cellulose (EHEC) and a hydrophobically modified analogue (HM-EHEC) in water in the presence of various amounts of sodium dodecyl sulfate (SDS) have been investigated by cloud point (CP) measurements, titration microcalorimetry, and static light scattering. The CP experiments revealed that the hydrophobically modified polymer is less soluble than the unmodi

Electron transport in InAs nanowires and heterostructure nanowire devices

Nanowires in the InAs/InP material system are grown with catalyst-assisted chemical beam epitaxy. Ohmic contacts are then fabricated to selected wires, allowing electron transport measurements to be carried out at room-temperature as well as at low T. InAs nanowires show strong quantum confinement effects, where thin wires (
