1. During early ontogeny, the serotonergic neurons in the brain stem of the three-spined stickleback shows a temporal and spatial developmental pattern that closely resembles that of amniotes. 2. However, in the adult fish, only the midline nuclei of the rostral group (dorsal and median raphe nuclei) and the dorsal lateral tegmental nucleus are consistently serotonin-immunoreactive (5-HTir), where

Metal carbides have shown great promise in a wide range of applications due to their unique catalytic, electrocatalytic and magnetic properties. However, the scalable production of dispersible metal carbide nanoparticles remains a challenge. Here, we report a simple and scalable route to dispersible iron carbide (Fe3C) nanoparticles. This uses MgO nanoparticles as a removable 'cast' to synthesize

This paper investigates flight-to-safety from stocks to bonds in six European markets. We use quantile regressions to identify flight-to-safety episodes. The conditional risk-return trade-off on the stock markets is negative. Flight-to-safety episodes strengthen the negative trade-off. The effects of flight-to-safety episodes on the trade-off are qualitatively similar for own country flight-to-saf

Wood is a hygroscopic material that absorbs and desorbs water to equilibrate to the ambient climate. Within material science, the moisture range from 0 to about 95-98% relative humidity is generally called the hygroscopic moisture range, while the exceeding moisture range is called the over-hygroscopic moisture range. For wood, the dominating mechanisms of moisture sorption are different in these

This experiment was designed to investigate how children cope with salient online advertising while engaging in task-oriented website interaction. 57 children in 3rd grade (9-year-olds) participated in the experiment. Each participant was introduced to a mock-up website and was instructed to solve two types of online tasks: reading for comprehension and information search. The web pages used by th

Many nocturnal animals, including invertebrates such as scorpions and a variety of vertebrate species, including toadlets, flying squirrels, owls, and nightjars, emit bright fluorescence under ultraviolet light. However, the ecological significance of this unique coloration so attached to nocturnality remains obscure. Here, we used an intensively studied population of migratory red-necked nightjar

This Letter presents the observation and measurement of electroweak production of a same-sign W boson pair in association with two jets using 36.1 fb-1 of proton-proton collision data recorded at a center-of-mass energy of s=13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed in the detector fiducial phase-space region, defined by the presence of two same-sign lept

Objective To compare several methods of missing data imputation for function (Health Assessment Questionnaire) and for disease activity (Disease Activity Score-28 and Clinical Disease Activity Index) in rheumatoid arthritis (RA) patients. Methods One thousand RA patients from observational cohort studies with complete data for function and disease activity at baseline, 6, 12 and 24 months were sel

Stora boken om barn och mat är en gedigen handbok i de fem första åren av barnets ätande. Här finns fakta och tips kring hur föräldrar kan stödja sitt barns ätutveckling, förebygga matallergier, hantera barns ätkrångel samt få maten så näringsrik som ett litet växande barn behöver.

An aim of molecular biomarkers is to stratify patients with cancer into disease subtypes predictive of outcome, improving diagnostic precision beyond clinical descriptors such as tumor stage1. Transcriptomic intratumor heterogeneity (RNA-ITH) has been shown to confound existing expression-based biomarkers across multiple cancer types2–6. Here, we analyze multi-region whole-exome and RNA sequencing

BALB/c mice were immunized with human islets of Langerhans and spleen cells from two mice. found to develop cell‐surface antibodies against insulin‐producing rat islet tumour RIN‐5F cells, were fused with mouse myeloma cells. Antibody‐producing hybrids were cloned on the basis of their production of surface antibodies reactive with paraformaldehyde‐fixed RIN‐5F cells by indirect immunofluorescence

Lymphocytes from patients with insulin-dependent diabetes have been shown to be sensitized to pancreatic tissue antigens. Mice immunized with homologous pancreatic islets have been found to develop glucose intolerance and insulitis. Since lymphocytes may be involved in diabetogenesis, we wished to determine if lymph node cells from islet-immunized mice can recognize and respond to islet cells in v

Spontaneous insulin-dependent diabetes mellitus (IDDM) in the BB rat is associated with the presence of antibodies to a 64-kilodalton rat islet cell protein. These protein antibodies appeared in young animals and remained for as long as 8 weeks before the clinical onset of IDDM. Antibodies to a 64-kilodalton human islet cell protein were found to be associated with human IDDM. Detection of the ant

We used the mouse passive transfer model to test whether islet cell antibodies affect β-cell function. The immunoglobulin (Ig) fraction of plasma from 5 islet cell surface antibody-positive, newly diagnosed insulin-dependent diabetic children or of a pool of plasma from 12 normal subjects was injected daily (7–16 mg IgG/day) for 14 days into normal immunosuppressed BALB/c mice. Insulin secretory r

ABSTRACT The pancreatic B‐cell function (glucose tolerance, C‐peptide release) and organ‐specific autoantibodies, including islet cell cytoplasmic and cell surface (mouse), were studied in 45 first‐degree relatives of patients with insulin‐dependent diabetes mellitus diagnosed before the age of 30 years. Compared to 107 healthy persons without any family history of either insulin‐dependent or non‐
