A Hypothalamic Switch for REM and Non-REM Sleep [PDF]

Neuron, 2018
Rapid eye movement (REM) and non-REM (NREM) sleep are controlled by specific neuronal circuits. Here we show that galanin-expressing GABAergic neurons in the dorsomedial hypothalamus (DMH) comprise separate subpopulations with opposing effects on REM versus NREM sleep.

Numerical solutions of the current distribution in superconducting cables [PDF]

, 1987
Superconducting cables are described by current sheets using the continuum model of W. Carr Jr. [1] and assuming an anisotropic conductivity. Two different situations are considered: a) finite length of cable in spatially independent magnetic field; b ...

Randomized Comparison of Cardiotoxicity With 60 Versus 90 mg Daunorubicin in AML Induction Therapy

American Journal of Hematology, EarlyView.
Early cardiac biomarker monitoring in AML induction therapy showed significantly higher hsTnT levels after daunorubicin 90 mg/m2 compared with 60 mg/m2, indicating a dose‐dependent early myocardial effect. ABSTRACT Anthracyclines are an essential component of induction therapy for acute myeloid leukemia (AML), but their optimal dosing and the ...

Association between Human Leukocyte Antigen Alleles and Neuropathological Outcomes in Lewy Body Disease

Annals of Neurology, EarlyView.
Objective Lewy body disease (LBD) is a complex neurodegenerative disorder characterized by the accumulation of misfolded α‐synuclein in the brain. Neuroinflammation has long been implicated in LBD pathogenesis, and recent genetic studies in Parkinson's disease (a clinical manifestation of LBD) have shown consistent association with the human leukocyte ...

Ecology and trophic role of Oncholaimus dyvae sp. nov. (Nematoda: Oncholaimidae) from the lucky strike hydrothermal vent field (Mid-Atlantic Ridge)

BMC Zoology, 2019
Background Nematodes are an important component of deep-sea hydrothermal vent communities, but only few nematode species are able to cope to the harsh conditions of the most active vent sites. The genus Oncholaimus is known to tolerate extreme geothermal

Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

Annals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

Sociality Affects REM Sleep Episode Duration Under Controlled Laboratory Conditions in the Rock Hyrax, Procavia capensis. [PDF]

, 2017
The rock hyrax, Procavia capensis, is a highly social, diurnal mammal. In the current study several physiologically measurable parameters of sleep, as well as the accompanying behavior, were recorded continuously from five rock hyraxes, for 72 h under ...
