Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst

Transplantation of progenitor cells to the CNS has shown promise in neuronal and glial replacement and as a means of rescuing host neurons from apoptosis. Here we examined the effect of progenitor grafts on neurite extension in the degenerating retina of rd1 ( retinal degeneration 1) mice. Transplantation of retinal progenitor cells induced increased matrix metalloproteinase-2( MMP2) secretion, pa

We have recently reported that the inner layers of the arteries, the intima-media complex, of common carotid artery, move as much in the longitudinal direction as in the radial direction, during the cardiac cycle. In order to study this phenomenon we have developed a high-resolution ultrasonic method that can simultaneously record both the longitudinal and the radial movements of the arterial wall

In this paper, we discuss the internet low bit rate codec (iLBC) with an emphesis on the frame-independent longterm prediction. The frame-independent long-term prediction is a method to exploit pitch-lag correlations in the encoding of speech without suffering multiple-frame speech degradation in connection with transmission loss. We present mean opinion scores for the iLBC codec and show by means

Informal caregiving is increasingly considered a health care delivery-resource within the North European welfare states. While ‘informal’ often refers to non-professional, ‘caregiving’ connotes both affective concern (caring about) and practical action (caring for). This duality of meanings, however, often refers to the one direction in which care is given. Care, we suggest, is relational and also

BACKGROUND: Prolonged opioid use (more than 90 days) after injury puts the patient at risk for adverse effects. We investigated the patterns of opioid prescription after distal radius fracture and the effect of pre- and post-fracture factors on the risk for prolonged use.METHODS: This register-based cohort study uses routinely collected health care data, including purchases of prescription opioids

Den snabba utvecklingen av elektrifiering av vägtransporter i Sverige kräver forskningsbaserade beslut om placeringen av laddinfrastruktur. Europeiska unionens (EU) nya förordning för infrastruktur för alternativa bränslen (AFIR) specificerar det maximala tillåtna avståndet mellan offentliga snabbladdningsstationer (FCS) för tunga lastbilar längs det transeuropeiska transportnätverket (TEN-T). EffThe rapid progression of the electrification of road transport in Sweden requires effective research based decisions on the location of charging infrastructure. The new European Union (EU) regulation for alternative fuel infrastructure (AFIR) specifies the maximum allowed distance between public fast-charging stations (FCSs) for heavy-duty trucks along the Trans-European Transport Network (TEN-T).

In 1934, Walter Benjamin published his major study Franz Kafka: Zur zehnten Wiederkehr seines Todestages. In the same year, Günther Anders, another German Jew in exile, gave a lecture on Kafka which later, in postwar years, developed into a small book titled Kafka, Pro und Contra. Bringing these two in dialogue—the much-celebrated essay by Benjamin and the generally overlooked book by Anders—the p

This paper discusses the role of mathematics in physics teaching and learning. The intention and strength of science is to describe what happens in the realworld by organizing explanations through theories and theoretical models. It has been widely suggested that learning in science is influenced by views about the nature of scientific knowledge. Furthermore, mathematics is an inherent part of the

The Large Interferometer For Exoplanets (LIFE) is a proposed space mission that enables the spectral characterization of the thermal emission of exoplanets in the solar neighborhood. The mission is designed to search for global atmospheric biosignatures on dozens of temperate terrestrial exoplanets and it will naturally investigate the diversity of other worlds. Here, we review the status of the m

CONTEXT: As part of a broader institutional initiative, the serious illness care program was implemented in a multi-site academic primary care practice. After 2 years, a minority was observed to be documenting serious illness conversations routinely.OBJECTIVES: We aimed to learn about the motivations and actions of clinicians who routinely conducted and documented serious illness conversations.MET

Accurate prediction of crack growth and strength in glued timber joints and components can be achieved by using cohesive laws in constitutive models. These laws represent the traction-separation relationship that measures the stress transmitted between crack faces in a cohesive zone, and can be obtained directly from experiments. However, studies on measuring the cohesive laws of wood adhesive bon

Problemställning: Dagens behov och önskemål från badgäster ställer stora krav på våra badanläggningar. Badgästerna vill ha möjlighet till olika alternativ på aktiviteter och service under ett och samma tak. Klimatet i badhuset måste därför anpassas så att detta blir möjligt. Erfarenheten har visat att denna utveckling lett till ett antal tekniska problem som måste lösas. Produktionserfarenheten fr

Evolutionsteorin förklarar hur djur och andra organismer förändras över tid. I dess historia beskrivs hur vi alla kommer från samma ursprung, från enkla organismer som uppstod för miljontals år sedan, till den otroliga mångfald och komplexitet som vi ser i naturen idag, inklusive oss människor. Vi människor härstammar allesammans från en aplik förfader som vi delar med schimpanser, och längre till
