Sensory structures associated with the cuticle of Hutchinsoniella macracantha (Crustacea, Cephalocarida)

The body cuticle of the cephalocarid crustacean Hutchinsoniella macracantha Sanders, 1955, carries two types of small setae which differ in their external shape and number of ciliated sensory cells. It also has two types of pores, one being a gland opening, the other containing the tip of a cilium. The setae and the pore type containing a ciliated sensory cell are considered chemosensory organs.

Serotonin- and FMRFamide-immunoreactive nerve elements in the chiton, Lepidopleurus asellus (Mollusca, Polyplacophora)

The distribution of serotonin-like and FMRFamide-like immunoreactive (5HT-ir and FMRFa-ir, respectively) neurons in the nervous system of the chiton Lepidopleurus asellus (Mollusca, Polyplacophora) was studied using an immunocytochemical technique. The neurons were distributed in characteristic patterns in the central nervous system, the 5HT-ir neurons predominating in the ventral (pedal) cords an

Patterns of enkephalin immunolabeling in the pulmonate snail Cepea nemoralis and related molluscs.

In the land pulmonate snailCepaea nemoralis, immunocytochemical localization of methionine- and leucine-enkephalin-like substances was demonstrated in specific populations of brain neurons. Methionine-enkephalin reactivity is also present in the peripheral nervous system as (i) abundant axonal projections of central neurons to the sole of the foot, and (ii) sparse local neurons of the head and man

Eliciting parents' individual requirements for an inclusive digital school system

Parents often have a busy time sorting out their life puzzles, including getting information about their children's activities in school. More and more communication between teachers and parents take place via digital school systems. It can be hard for parents to find the information they are looking for and the teacher decides when information is sent and what communication method to use. All par

The light-yield response of a NE-213 liquid-scintillator detector measured using 2–6 MeV tagged neutrons

The response of a NE-213 liquid-scintillator detector has been measured using tagged neutrons from 2 to 6 MeV originating from an Am/Be neutron source. The neutron energies were determined using the time-of-flight technique. Pulse-shape discrimination was employed to discern between gamma-rays and neutrons. The behavior of both the fast (35 ns) and the combined fast and slow (475 ns) components of

A new biological recovery approach for PHA using mealworm, Tenebrio molitor

Bacterial polyhydroxyalkanoates (PHA) are expensive partly due to the recovery and purification processes. Thus, many studies have been carried out in order to minimize the cost. Here we report on the use of mealworm, which is the larva of mealworm beetle (Tenebrio molitor) to recover PHA granules from Cupriavidus necator. Mealworms were shown to readily consume the freeze-dried C. necator cells a

Assessing the capabilites to manage risks in energy systems–analytical perspectives and frameworks with a starting point in Swedish experiences

In this study we conceptualise how a capability approach could be used for analysing the conditions for preserving security of energy supply. We derive a concept, ‘energy system capability’, to describe how well the system is designed for this purpose. Based on a socio-technical systems perspective, we suggest that this capability is composed of five categories of ‘building blocks’: technical stru

A genome-wide association study in multiple system atrophy

Objective: To identify genetic variants that play a role in the pathogenesis of multiple system atrophy (MSA), we undertook a genome-wide association study (GWAS). Methods: We performed a GWAS with >5 million genotyped and imputed single nucleotide polymorphisms (SNPs) in 918 patients with MSA of European ancestry and 3,864 controls. MSA cases were collected from North American and European center

SIKs control osteocyte responses to parathyroid hormone

Parathyroid hormone (PTH) activates receptors on osteocytes to orchestrate bone formation and resorption. Here we show that PTH inhibition of SOST (sclerostin), a WNT antagonist, requires HDAC4 and HDAC5, whereas PTH stimulation of RANKL, a stimulator of bone resorption, requires CRTC2. Salt inducible kinases (SIKs) control subcellular localization of HDAC4/5 and CRTC2. PTH regulates both HDAC4/5

Path creation in Nordic energy and road transport systems – the role of technological characteristics

This paper reviews path-creation processes in road transport systems in the Nordic countries: e-mobility in Denmark, hydrogen and fuel-cell electrical vehicles in Norway, and advanced biofuels in Finland and Sweden. The study builds on the path creation literature, which seeks to explain the emergence of new technological pathways. Drawing on recent insights concerning the differences between desi

Att kunna och vilja arbeta längre

Möjligheten att arbeta till en högre ålder är en komplex och mångdimensionell fråga som inkluderar många faktorer. Den teoretiska modellen som beskrivs visar på komplexiteten Möjligheten att arbeta påverkas på olika nivåer, och det beror inte enbart på individen utan det är i första hand chefer, organisationer och företag som skapar förutsättningarna för de äldre medarbetarna på arbetsplatsen och

Ascending stair evacuation: walking speed as a function of height

There is reason to believe that factors such as physical exertion and behavioural changes will influence the ascending walking speed and ultimately the possibility of satisfactory evacuation. To study these effects, a 2-year research project was initiated with the focus on effects of physical exertion on walking speeds, physiological performance and behaviours during long ascending evacuations. Tw

Creating a safe haven-women's experiences of the midwife's professional skills during planned home birth in four Nordic countries

OBJECTIVE: The midwife assisting a birth has a considerable influence on the woman's experience of the birth. The aim of this study was to investigate the experience of the midwife's professional skills among women in Norway, Denmark, Iceland, and Sweden who chose a planned home birth.DESIGN AND SETTING: All known home birth midwives were asked to inform the mothers about the project and invite th

The prognostic impact of COX-2 expression in breast cancer depends on oral contraceptive history, preoperative NSAID use, and tumor size

The association between tumor cyclooxygenase 2 (COX-2) expression and breast cancer prognosis has been inconsistent. The purpose of this study was to evaluate the prognostic significance of COX-2 tumor expression according to adjuvant treatment, and potential effect modifications of non-steroid anti-inflammatory drug (NSAID) use, and other tumor and lifestyle factors. A prospective cohort of 1,116

Experiences of using powered wheelchair or powered scooter and accessibility in housings

OBJECTIVE: To describe powered wheelchair (PW) and powered scooter (PS) users' experiences of accessibility and housing adaptions in their homes.METHOD: A qualitative research approach with focus group methodology was used. Four focus groups were created, with men and women as well as PW and PS users in different groups. Applying a descriptive approach, data were analysed according to the principl

Clinical application of a microcomputer system for analysis of monophasic action potentials

UNLABELLED: Computerized analysis of monophasic action potentials (MAPs) has rarely been reported in clinical setting. We developed a computer system featuring on-line acquisition and user-monitored automatic measurement of multichannel MAPs with the capability of manual corrections. This system has been used in 34 patients in whom two-channel MAPs and 1-lead ECG were digitized during sinus rhythm

Effect of dofetilide on cardiac repolarization in patients with ventricular tachycardia. A study using simultaneous monophasic action potential recordings from two sites in the right ventricle

Monophasic action potentials (MAP) were simultaneously recorded from the right ventricular (RV) apex (RVA) and the outflow tract (RVOT) before and after an infusion of dofetilide in 10 patients with documented ventricular tachycardia. After the drug infusion, the MAP duration (MAPd), repolarization time, and corrected QT interval were significantly prolonged during sinus rhythm, RV pacing, and RV
