The dolphin-like ichthyosaurs – also known as ‘fish lizards’ – are extinct marine reptiles that roamed the Mesozoic oceans for some 160 million years. As for most ancient vertebrates, our knowledge of these iconic animals largely derives from biomineralized hard parts (teeth and bones). However, soft tissues are also known from a number of Lagerstätte specimens, and have opened up new avenues for

This is a comment on Michaelian and Simeonov (2015). Michaelian and Simeonov formulate the leading thought in their article: “The driving force behind the origin and evolution of life has been the thermodynamic imperative of increasing the entropy production of the biosphere through increasing the global solar photon dissipation rate”. I shall in the following try to provide some information that

Background: Arterial stiffness is independently associated with orthostatic hypotension. We aimed to investigate the relationship between orthostatic blood pressure reaction and arterial stiffness as well as central hemodynamics in younger subjects from the general population.Methods: We analyzed a large prospective cohort study of 3756 individuals from the general population (mean age 41.9±14.5 y

Oxygenic photosynthesis takes place in thylakoid membranes (TM) of cyanobacteria, algae, and higher plants. Itbegins with light absorption by pigments in large (modular) assemblies of pigment-binding proteins, which thentransfer excitation energy to the photosynthetic reaction centers of photosystem (PS) I and PSII. In green algaeand plants, these light-harvesting protein complexes contain chlorop

The Polycomb complex protein Bmi1 is regarded as a master regulator of hematopoietic stem cells (HSCs). In the blood system, HSCs express Bmi1 most abundantly and Bmi1 expression vanes as cells differentiate. Furthermore, Bmi1 has been found overexpressed in several hematologic cancers. Most studies exploring the normal role of Bmi1 in HSC biology have utilized loss-of-function models, which have

INTRODUCTION: Childbirth is a life-changing event where fathers desire being involved. As fathers take a more active role, fear of childbirth can arise. The aim of this study was to explore fathers' experiences of childbirth fear during pregnancy and after the birth of their baby.METHODS: This was a qualitative longitudinal prospective study that included 14 interviews with seven fathers, one duri

Introduction:The timing of cord clamping impacts children’s short- and longterm well-being. When making clinical decisions, midwives incorporate their tacit and professional knowledge, experience and current evidence. There appears to be a lack of knowledge regarding Swedish midwives’ management of the third stage of labor and cord clamping practice. The aim of this study was to explore Swedish mi

Background:The goal of postnatal care is to provide the highest possible quality of care and medical safety with the least possibleintervention in order to optimize health and wellbeing of the new family. The aim of the study was to describemothers´ experiences in relation to a new postnatal home-based model of midwifery care.Method:Prospective cross sectional study based on quantitative and quali

Genom att ställa hälso- och sjukvårdskuratorns uppdrag i relation till det som feministiska och marxistiska forskare kallat ”vårdens moraliska ekonomi” bidrar artikeln till att fördjupa förståelsen av kuratorns betydelse i samhällets reproduktiva sfär. Begreppet ”vårdens moraliska ekonomi” syftar på de ”bindningar och skyldigheter” som mer än själva anställningskontraktet formar de vårdande profes

The delay or refusal of vaccination, which defines vaccine hesitancy, is a major challenge to successful control of COVID-19 epidemic. The huge number of publications addressing COVID-19 vaccine hesitancy necessitates periodic review to provide a concise summary of COVID-19 vaccine acceptance rates worldwide. In the current narrative review, data on COVID-19 vaccine acceptance rates were retrieved

This paper will report on four machine translation projects dealing with restricted domains and controlled or semi-controlled language. The computer program Seatra translates marine forecasts between Swedish and English. It is in daily use by the Swedish meteorological agency (SMHI) and generally needs no postediting. The same basic program but with different lexicons is used in the program Maltra

Alkaline membrane fuel cells can operate using nonprecious metals as catalysts, but rely on polymeric membranes with high hydroxide conductivity and alkali-resistance, which are hard to find. A new membrane is now reported comprising ferrocenium cations in magnetically aligned domains with an excellent combination of these properties.

Background: It is a critical challenge to diagnose leptomeningeal metastasis (LM), given its technical difficulty and the lack of typical symptoms. The existing gold standard of diagnosing LM is to use positive cerebrospinal fluid (CSF) cytology, which consumes significantly more time to classify cells under a microscope.Objective: This study aims to establish a deep learning model to classify can

Animals normally vocalise while exhaling. Ingressive, or inspiratory, voice production occurs in humans and many other species, but its communicative function, if any, remains unknown. To test the perceptual effects of ingressive phonation, naturally occurring ingressive syllables in 109 human nonverbal vocalisations (55 laughs, 21 cries, and 33 moans) were experimentally attenuated or morphed int
