Deaths after confirmed SARS-CoV-2 in Norway.

Background: Advanced age is the most important risk factor for death as a result of COVID-19, but there is a dearth of knowledge regarding the impact of chronic diseases. Using health registry data, we describe the disease profiles of persons who died after a confirmed infection with SARS-CoV-2 during the first three months of the pandemic in Norway.

Material And Method: Data from the specialist health service (Norwegian Patient Registry, NPR) and the primary health service (Norwegian Registry for Primary Health Care, NRPHC) were linked to information on positive tests for SARS-CoV-2 from the Norwegian Surveillance System for Communicable Diseases (MSIS) and on deaths from the National Population Register.

Underlying conditions in adults with COVID-19.

Background: Cardiovascular diseases, cancer, type-2 diabetes and chronic obstructive pulmonary disease (COPD) were initially noted as the most common diseases among individuals who were hospitalised for COVID-19. However, the evidence base is weak. The objective of this study is to describe how selected diseases were distributed among adults with confirmed COVID-19 (COVID-19 positive tests) and among those hospitalised for COVID-19 compared to the general population.

The Norwegian Patient Registry and the Norwegian Registry for Primary Health Care: Research potential of two nationwide health-care registries.

In Norway, the Directorate of Health is responsible for two nationwide registries - the Norwegian Patient Registry (NPR) and the Norwegian Registry for Primary Health Care (NRPHC) - which together cover all governmental-funded health care. The NPR (specialist health care) was established in 2008, while the NRPHC (primary health care) was established in 2017. Data from the NPR are extensively used in a large variety of studies.

Surface plasmon resonance detection of blood coagulation and platelet adhesion under venous and arterial shear conditions.

A surface plasmon resonance (SPR) based flow chamber device was designed for real time detection of blood coagulation and platelet adhesion in platelet rich plasma (PRP) and whole blood. The system allowed the detection of surface interactions throughout the 6mm length of the flow chamber. After deposition of thromboplastin onto a section of the sensor surface near the inlet of the flow chamber, coagulation was detected downstream of this position corresponding to a SPR signal of 7 to 8 mRIU (7 to 8 ng/mm2).

Phosphorylation of Thr654 but not Thr669 within the juxtamembrane domain of the EGF receptor inhibits calmodulin binding.

Calcium-calmodulin (CaM) binding to the epidermal growth factor receptor (EGFR) has been shown to both inhibit and stimulate receptor activity. CaM binds to the intracellular juxtamembrane (JM) domain (Met645-Phe688) of EGFR. Protein kinase C (PKC) mediated phosphorylation of Thr654 occurs within this domain.

Interactions between the juxtamembrane domain of the EGFR and calmodulin measured by surface plasmon resonance.

One early response to epidermal growth factor receptor (EGFR) activation is an increase in intracellular calcium. We have used surface plasmon resonance (SPR) to study real-time interactions between the intracellular juxtamembrane (JM) region of EGFR and calmodulin. The EGFR-JM (Met(644)-Phe(688)) was expressed as a GST fusion protein and immobilised on a sensor chip surface.
