Background: Myocardial performance index (MPI) has been investigated in a variety of populations, but the effect of food intake has not been evaluated. We assessed whether myocardial performance index is affected by food intake in healthy subjects. Methods: Twenty-three healthy subjects aged 25.6 ± 4.5 years were investigated. MPI was measured before, 30 min after, and 110 min after a standardized

Ostreopsis ovata is a benthic dinoflagellate that produces palytoxin and its analogues. Since the end of the 1990s, toxic blooms of O. ovata have been recorded in many tropical and temperate marine waters. These blooms often kill benthic invertebrates and cause health problems for humans. We hypothesize that increases in seawater temperature might induce these blooms. A strain of O. ovata isolated
Syftet med detta arbete var att designa och bygga en externt driven proteshand. Handen ska helst ha en eller flera funktioner som inte finns hos andra protester. Den mänskliga handen är väldigt komplex, den innehåller över 30 muskler och minst 18 leder. Jämförelsevis har en komplex och rörlig kommersiell protes fem aktuatorer och elva leder, men endast en eller två kontrollsignaler. Allt som allt The purpose of the thesis was to design and build an externally powered prosthetic hand. The hand should preferably have one or more new functionalities not found in other prostheses. The human hand is very complex, it contains over 30 muscles and at least 18 joints. In comparison, a complex and dexterous commercial prostheses has five actuators and eleven joints, but only one or two control signa
Little has been published about specific problems that may occur during long-distance transports of newborn cardiac patients. During a 4-year period after centralization of pediatric heart surgery in Sweden, 286 transports were prospectively investigated. A majority (77.3%) of the transports were carried out by nonspecialized teams. Ten severe adverse events, including the death of 1 infant, occur
This study of 17,443 childbearing women, investigated the relationship between hospital admissions 5 years prior to index birth, type of mental disorders and risk factors for mode of delivery. Hospital based electronic perinatal medical records between 2001 and 2006, were linked with the Swedish National Inpatient Care Registry 1996-2006. Of all the women, 39.3% had had inpatient care prior to ind
This article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s. Both labourers and farmers improved their material living standards – as measured by the contents of probate inventories – but the labouring households’ ownership of means of production decreased over time
This paper takes as a point of departure the analysis of complex blade industries as a proxy for cultural practices, socially learned and transmitted habits within a human network. Our main objective is to study how traditions and/or habits are protected and reproduced or changed as groups of people are confronted with changed natural and/or social environments. Our case study is the hypothesized
Mauritius is an African growth miracle when evaluated against traditional economic theory on how to achieve sustained growth and structural transformation. Mauritius has also been recognized for its commitment to human development. Still, gendered inequalities in the labour market remain.Garment manufacturing significantly contributed to raising women’s labour force participation in Mauritius’s po
För närvarande finns en stark trend med forskningsmiljöer där flera ämnen samverkar och där forskare inom flera fält samarbetar, exempelvis geriatrik, psykologi, psykiatri, arbetsterapi och hälsoekonomi. Forskare i tvärvetenskapen blir ofta eftersatta och hittar inte alltid det stöd de behöver i det kursutbud som erbjuds idag inom ramen för informationshantering. Lunds universitets bibliotek är en
Red blood cells may regulate tissue circulation and O-2 delivery by releasing the vasodilator ATP in response to hypoxia. When released extracellularly, ATP is rapidly degraded to ADP in the circulation by ectonucleotidases. In this study, we show that ADP acting on P2Y(13) receptors on red blood cells serves as a negative feedback pathway for the inhibition of ATP release. mRNA of the ADP recepto
Purpose: To determine how image quality linked to tumor detection is affected by reducing the absorbed dose to 50% and 30% of the clinical levels represented by an average glandular dose (AGD) level of 1.3 mGy for a standard breast according to European guidelines. Materials and methods: 90 normal, unprocessed images were acquired from the screening department using a full-field digital mammograph
The bit-error rate of a 60 GHz wireless impulse radio link is investigated at a bit-rate of 4 Gbps using on-off keying. The measurement results show that it is possible to have a BER below 10(-12), and the measured BER vs. E-b/N-o is approximately 1 dB from the theoretical value. The reliability of the wideband 60 GHz wavelet generator is furthermore confirmed by studying the number of faulty wave
BACKGROUND: Septic shock may cause splanchnic hypoperfusion. We hypothesized that levosimendan would improve systemic and hepatosplanchnic perfusion during endotoxemic shock. METHODS: In 16 anesthetized pigs (31.4 +/- 3.4 kg), a jugular vein, a carotid artery, the Pulmonary artery (thermodilution), the portal vein, and a hepatic vein were cannulated for hemodynamic monitoring and blood sampling. U
The biosynthesis of chlorophyll, an essential cofactor for photosynthesis, requires the ATP-dependent insertion of Mg2+ into protoporphyrin IX catalyzed by the multisubunit enzyme magnesium chelatase. This enzyme complex consists of the I subunit, an ATPase that forms a complex with the D subunit, and an H subunit that binds both the protoporphyrin substrate and the magnesium protoporphyrin produc
Implant-assisted targeting of magnetic particles under the influence of an external magnetic field has previously been verified through mathematical modeling, in vitro studies, and in vivo studies on rat carotid arteries as a feasible method for localized drug delivery. The present study focuses on the development of nanoparticles for the treatment of in-stent thrombosis. Magnetic nanoparticles in
Zambia introduced a sector-wide approach (SWAp) in the health sector in 1993. The goal was to improve efficiency in the use of domestic funds and externally sourced development assistance by integrating these into a joint sectoral framework. Over a decade into its existence, however, the SWAp remains largely unevaluated. This study explores whether the envisaged improvements have been achieved by
The statistical relation between ocean wave geometry and water particle movements can be formulated in the stochastic Gauss-Lagrange model. In this paper we use Slepian models to get detailed information of the sea surface elevation in the neighbourhood of local maxima in a Gaussian wave model and of the movements of the top particle of the waves. We present full conditional distributions of the GThe statistical relation between ocean wave geometry and water particle movements can be formulated in the stochastic Gauss-Lagrange model.

Knowledge of DNA - lipid layer interactions is key for the development of biosensors, synthetic nanopores, scaffolds, and gene-delivery systems. These interactions are strongly affected by the ionic composition of the solvent. We have combined quartz crystal microbalance (QCM) and ellipsometry measurements to reveal how pH, buffers and alkali metal chloride salts affect the interaction of DNA with
