Hormone-sensitive lipase (HSL) plays a key role in lipid metabolism and overall energy homoeostasis, by controlling the release of fatty acids from stored triglycerides in adipose tissue. Lipases and esterases form a protein superfamily with a common structural fold, called the alpha/beta-hydrolase fold, and a catalytic triad of serine, aspartic or glutamic acid and histidine.

A method is described for imaging in 3-D the interiors of meteoritic chromite grains and their inclusions using synchrotron radiation X-ray tomographic microscopy. In ordinary chondrites, chromite is the only common mineral that survives long-term weathering on Earth. Information about the silicate matrix of the original meteorite, however, can be derived from mineral inclusions preserved in the p
1. Human activities have promoted the spread of species worldwide. Several crayfish species have been introduced into new areas, posing a threat to native crayfish and other biota. Invader success may depend on the ability to utilise a wide variety of habitats and resources. Successful invaders are generally expected to have broader niches and to be more plastic than non-invasive species. 2. Using
Popular Abstract in Swedish Huntingtons sjukdom (HS) är en ärftlig och dödlig sjukdom som karakteriseras av ofrivilliga, danslika rörelser vilket gjort att den i folkmun kallas för danssjuka. Diagnosen ställs när de motoriska problemen (ofrivilliga rörelserna) uppträder, vanligtvis i medelåldern, och dessa ökar sedan gradvis och den drabbade personen avlider på grund av sjukdomen efter cirka 15-25
As their most critical limitation, neighborhood and health studies published to date have not taken into account nonresidential activity places where individuals travel in their daily lives. However, identifying low-mobility populations residing in low-resource environments, assessing cumulative environmental exposures over multiple activity places, and identifying specific activity locations for
The modernisation of Swedish households during the twentieth century prompted a considerable productivity growth in household production. This paper examines the association between this process and the allocation of female time in Swedish urban households during the period 1920-1990. Estimates presented in the paper suggest a minimum potential time reduction for a fixed volume of routine househol
The use of folic acid prior to conception is generally recommended for the prevention of birth defects, notably neural tube defects. In a previous study from Sweden, based on interviews of women in early pregnancy, no such effect was found on the general malformation rate, but data for neural tube defects were scarce. Using data from the Swedish Medical Birth Register for the years 1995-2004, 20 8
We examine the evolutionary stability of year-round residency in territorial populations, where breeding sites are a limiting resource. The model links individual life histories to the population-wide competition for territories and includes spatial variation in habitat quality as well as a potential parent-offspring conflict over territory ownership. The general form of the model makes it applica
