The Alzheimer's Association international guidelines for handling of cerebrospinal fluid for routine clinical measurements of amyloid β and tau

The core cerebrospinal fluid (CSF) Alzheimer's disease (AD) biomarkers amyloid beta (Aβ42 and Aβ40), total tau, and phosphorylated tau, have been extensively clinically validated, with very high diagnostic performance for AD, including the early phases of the disease. However, between-center differences in pre-analytical procedures may contribute to variability in measurements across laboratories.

IR and Metasurface based mm-Wave Camera

We have developed a technique to measure low-power electromagnetic fields from mm-wave devices non-intrusively by combining a metasurface, designed to absorb power and focus the radiated power in a thermally isolated region, with an infrared camera. The metasurface consists of thermally isolated elements of low mass and highly emissive material for maximal IR conversion of the incident wave. The I

Report from the European Society of Gynaecological Oncology (ESGO) 2020 State-of-the-Art Virtual Meeting

This is a report from the European Society of Gynaecological Oncology State-of-the-Art Virtual Meeting held December 14-16, 2020. The unique 3-day conference offered comprehensive state-of-the-art summaries on the major advances in the treatment of different types of gynecological cancers. Sessions opened with a case presentation followed by a keynote lecture and interactive debates with opinion l

A comprehensive study on cutting mechanisms and surface integrity of AISI 304 when turning a curved surface

Most of the studies on cutting mechanisms and surface integrity in turning are investigated with a straight tool path (longitudinal/end face turning) while few contributions have been done in curved surface turning. This work explores the evolutions of cutting force, chip morphology and surface integrity when turning a curved surface, using fillet surface machining of AISI 304 stainless steel. The

Improvement of platelet respiration by cell-permeable succinate in diabetic patients treated with statins

Diabetes mellitus (DM) is the most severe metabolic disease that reached the level of a global pandemic and is associated with high cardiovascular morbidity. Statins are the first-line lipid- lowering therapy in diabetic patients with or without a history of atherosclerotic disease. Although well tolerated, chronic treatment may result in side effects that lead to treatment interruption. Mitochond

Associations of breastfeeding with childhood autoimmunity, allergies, and overweight : The Environmental Determinants of Diabetes in the Young (TEDDY) study

BACKGROUND: Breastfeeding has beneficial effects on numerous health outcomes.OBJECTIVES: We investigated whether breastfeeding duration is associated with the development of early childhood autoimmunity, allergies, or obesity in a multinational prospective birth cohort.METHODS: Infants with genetic susceptibility for type 1 diabetes (n = 8676) were followed for the development of autoantibodies to

AMP-activated protein kinase in adipose tissue

The AMP-activated protein kinase (AMPK) is a ubiquitously expressed kinase, which is activated in response to depletion of cellularenergy levels. Once active, it functions to alter cellular metabolism in a way that leads to restoration of energy levels. Therefore,AMPK is described as the key regulator of cellular energy homeostasis. Over the past years, AMPK activation has gained increasingattenti

Exploring Paths of Justice in the Digital Healthcare : A Socio-Legal Study of Swedish Online Doctors

Nätläkare, vårdgivare som tillhandahåller sjukvårdstjänster via smartphoneappar, har gått från att vara perifera inslag i den svenska sjukvården till att på allvar utmana det konventionella sättet att bedriva sjukvård. Den tillgänglighet som nätläkare erbjuder är oöverträffad men alla patientgrupper har inte sett sin tillgång till vård förbättras i samma utsträckning tack vare nätläkare.Syftet medOnline doctor services, healthcare provided via smartphone apps, have gone from being peripheral to seriously challenging the conventional Swedish way of providing healthcare services. The accessibility of online doctors is unsurpassed but all patient groups have not gotten better access to healthcare thanks to online doctors.The aim of this study was to investigate how perceptions of the online d

The Attack on Natanz and the JCPOA

In the morning hours of April 11, the Natanz nuclear facility in Iran was attacked, allegedly by Israel. The strike came at a sensitive time, as Iran and world powers are discussing Washington’s return to the Joint Comprehensive Plan of Action (JCPOA) and the removal of sanctions. According to Israeli estimates, as the Islamic Republic does not wish to jeopardize a US return to the JCPOA, its resp

Isothermal Reduction of IrO2(110) Films by Methane Investigated Using in Situ X-ray Photoelectron Spectroscopy

Continuous exposure to methane causes IrO2(110) films on Ir(100) to undergo extensive reduction at temperatures from 500 to 650 K. Measurements using in situ X-ray photoelectron spectroscopy (XPS) confirm that CH4 oxidation on IrO2(110) converts so-called bridging oxygen atoms (Obr) at the surface to HObr groups while concurrently removing oxygen from the oxide film. Reduction of the IrO2(110) fil

Sharing Economy Business Models for Sustainability

The sharing economy is not sustainable by default – search for images of bikesharing graveyards. But, with careful design of the business models that facilitate access over ownership, the sharing economy can increase intensity of use and material efficiency, contributing to sustainable consumption. In this episode, co-host Steven Curtis shares with us his research on sharing economy business model

High-resolution genotyping of HLA class I loci in children with type 1 diabetes and celiac disease

Objectives: HLA-DQ2 and DQ8 contribute to the strongest risk haplotypes for type 1 diabetes (T1D) and celiac disease (CD). The variation in genetic risk association is likely linked to different HLA class II loci susceptibility, but association studies of HLA class I alleles are scarce. The aim was to investigate HLA class I A, B, and C alleles polymorphisms in children with only T1D, CD, and a su

The combined impact of ankle–brachial index and transcutaneous oxygen pressure on mortality in patients with type 2 diabetes and foot ulcers

Aims: A diabetic foot ulcer (DFU) is associated with increased cardiovascular risk and mortality, independently of ulcer etiology (ischemic, neuro-ischemic or neuropathic). Ankle–brachial index (ABI) is the most commonly used test when diagnosing peripheral macrovascular disease and is a well-known marker for increased cardiovascular risk. Transcutaneous oxygen pressure (TcPO2) is considered to be

The novel collagen matrikine, endotrophin, is associated with mortality and cardiovascular events in patients with atherosclerosis

Background: Rupture of atherosclerotic plaques is the major cause of acute cardiovascular events. The biomarker PRO-C6 measuring Endotrophin, a matrikine of collagen type VI, may provide valuable information detecting subjects in need of intensified strategies for secondary prevention. Objective: In this study, we evaluate endotrophin in human atherosclerotic plaques and circulating levels of PRO-

Soluble P-tau217 reflects amyloid and tau pathology and mediates the association of amyloid with tau

Alzheimer’s disease is characterized by β-amyloid plaques and tau tangles. Plasma levels of phospho-tau217 (P-tau217) accurately differentiate Alzheimer’s disease dementia from other dementias, but it is unclear to what degree this reflects β-amyloid plaque accumulation, tau tangle accumulation, or both. In a cohort with post-mortem neuropathological data (N = 88), both plaque and tangle density c
