Serotonin (5-HT) is a biogenic monoamine that functions both as a neurotransmitter and a circulating hormone. Recently, the metabolic effects of 5-HT have gained interest and peripheral 5-HT has been proposed to influence lipid metabolism in various ways. Here, we investigated the metabolic effects of 5-HT in isolated, primary rat adipose cells. Incubation with 5-HT suppressed β-adrenergically sti

The report offers an analysis of the R&I system in Sweden for 2015, including relevant policies and funding, taking into account the priorities of the European Research Area and the Innovation Union. The report was prepared according to a set of guidelines for collecting and analysing a range of materials, including policy documents, statistics, evaluation reports, websites, etc. The quantitat

The radiocarbon concentration of different atherosclerotic plaque fragments obtained from 20 patients in Portugal, operated in 2000-2001, has been measured in order to define the year of plaque formation. A difference of 1.8-15 yr was observed, with the mean and median both 9 yr, between the bomb-pulse date estimated with the CALIBomb software and the operation date. Stable isotope (delta C-13 and

Objective: The auditory brainstem response (ABR) is often affected in neurodevelopmental disorders. The aim of this study was to investigate gender differences in ABR between young females and young males with ADHD, compared to control subjects. Method: We studied 63 females with ADHD (mean 13.8 years), 26 female controls (mean 13.8years), 48 males with ADHD (mean 13.1 years), and 20 male controls

Background: Activated phosphoinositide 3-kinase δ syndrome (APDS) 2 (p110δ-activating mutations causing senescent T cells, lymphadenopathy, and immunodeficiency [PASLI]-R1), a recently described primary immunodeficiency, results from autosomal dominant mutations in PIK3R1, the gene encoding the regulatory subunit (p85α, p55α, and p50α) of class IA phosphoinositide 3-kinases. Objectives: We sought

This paper focuses on how older people in Sweden imagine the potential role of robots in their lives. The data collection involved mixed methods, including focus groups, a workshop, a questionnaire and interviews. The findings obtained and lessons learnt from one method fed into another. In total, 88 older people were involved. The results indicate that the expectations and preconceptions about ro

Lund University has offered the Sida-financed International Training Programmeon Child Rights, Classroom and School Management since 2003.The programme targets those in a position from which they can initiate processesof change in the education sector in their countries. During the programmeall participating teams initiate a change project in their respectivecountries aiming at the realization of

The purpose of this work is to develop and implement a simple and robust preservation technology that can enhance food and economic security and thereby improve the lives of people in developing countries. The technique under development is termed “solar assisted pervaporation (SAP)”. It is a sustainable technology whereby fruit juices or purées are concentrated using reusable pouches made of “bre

Den 15 mars hoppade Felix Baumgartner från 22 km höjd. Detta var ett steg på vägen att slå det tidigare höjdrekordet: Joe Kittinger hoppade 1960 hoppade från en heliumballong på mer än 3 mils höjd, som en del av USAs rymdprogam. Att man kan komma så högt med en heliumballong, och sedan falla mot jorden, medan temperaturen varierar och luftens densitet och luftmotståndet hela tiden ökar, inbjuder t

Hopp från ballonger på flera mils höjd inbjuder till fysiksamtal.

Due to the increasing power requirement and the limited available space in vehicles, placing the heat exchanger at the roof or the underbody of vehicles might increase the possibility to handle the cooling requirement. A new configuration of the heat exchanger has to be developed to accommodate with the position change. In this paper, a countercurrent heat exchanger is developed for position on th

Many studies assume a respiratory quotient (RQ = molar ratio of CO2 produced to O2 consumed) close to 1 when calculating bacterioplankton respiration. However, evidence suggests that RQ depends on the chemical composition of the respired substrate pool that may be altered by photo-chemical production of oxygen-rich substrates, resulting in elevated RQs. Here we conducted a novel study of the impac
