Microelectrode cluster technology for precise interactions with neuronal circuits. Towards highly specific adaptive deep brain stimulation.

Neuro-electronic interfaces, which can be used for stable communication between neurons-computers over long periods of time, would be valuable for understanding and interacting with the nervous system. A major challenge has been to overcome the tissue reactions towards implanted electrodes. Flexible microelectrodes that cause less implantation injury and which can follow the micromotions of the br

The Association Between Hemoglobin Upswing in the Reference Range and Sleep Apnea Syndrome

PurposeSleep apnea syndrome (SAS) is a relatively common disorder, but many patients with SAS are still undiagnosed. Using Japanese annual health check and medical claims data, we analyzed the association between hemoglobin upswing, defined as an increase in hemoglobin level within the reference range, and the incidence of SAS.MethodsIn this study, we used the Japan Medical Database Center (JMDC)

Tracking and recognitional use of Kalamang "opa" : Demonstrative of cognitive accessibility

The Papuan language Kalamang has an adnominal demonstrativeopa, which marksreferents that are cognitively accessible either because they are common ground orbecause they are previously mentioned in the discourse. It is mainly an endophoricdemonstrative which has tracking and recognitional uses, but it can be used ex-ophorically as well. It can be used for both maintaining and reintroducing refer-e

Germline Genome Editing Research : What Are Gamete Donors (Not) Informed about in Consent Forms?

The potential for using germline genome editing (GGE) in humans has garnered a lot of attention, both for its scientific possibilities as well as for the ethical, legal, and social challenges it ignites. The ethical debate has focused primarily on the suggestions of using GGE to establish a pregnancy (i.e., to offer it in a clinical setting), which is, to date, illegal in many jurisdictions. The u

Risk Shifting or Risk Management: How do Firms Hedge in Financial Distress?

In this paper we address the question of how firms hedge in financial distress. Using hand-collected data from oil and gas producers, we show thatthe uniquecharacteristic of derivative portfolios in distressed firms is a strategythat involvessold put options. This is puzzling, considering that selling put options amounts to selling insurance, which creates a new liability that distressed firms seeIn this paper we address the question of how firms hedge in financial distress.Using hand-collected data from oil and gas producers, we show that the uniquecharacteristic of derivative portfolios in distressed firms is a strategy thatinvolves sold put options.

The influence of microstructure on crack propagation in cortical bone at the mesoscale

The microstructure of cortical bone is key for the tissue's high toughness and strength and efficient toughening mechanisms have been identified at the microscale, for example when propagating cracks interact with the osteonal microstructure. Finite element models have been proposed as suitable tools for analyzing the complex link between the local tissue structure and the fracture resistance of c

The proteoglycan mimecan is associated with carotid plaque vulnerability and increased risk of future cardiovascular death

Background and aims: A vulnerable plaque is an atherosclerotic plaque that is rupture-prone with a higher risk to cause cardiovascular symptoms such as myocardial infarction or stroke. Mimecan or osteoglycin is a small leucine-rich proteoglycan, important for collagen fibrillogenesis, that has been implicated in atherosclerotic disease, yet the role of mimecan in human atherosclerotic disease rema

Association of coronary calcium score with endothelial dysfunction and arterial stiffness

Background and aims: The aim of the study was to determine potential associations between endothelial dysfunction and arterial stiffness, measured by peripheral arterial tonometry, and coronary artery calcium score (CACS) assessed by computed tomography (CT). Methods and results: The BIG3 study is a prospective longitudinal, non-interventional, pulmonary-cardiovascular cohort study exploring the t
