Human endogenous retroviruses (HERVs) are estimated to represent at least 1% of the human genome. An HERV-H env SU sequence (HERV-H19) was used to screen the high-throughput (htgs) and nonredundant (nr) databases for other HERV-H SU open reading frames (ORFs) and thus possible functional proteins. Using PCR with primers derived from HERV-H19 SU, we also obtained several new sequences with ORFs fro
Large-scale protein conformational motions on nanosecond – microsecond time scales are important for many biological processes, but remain largely unexplored because of methodological limitations. NMR relaxation methods can access these time scales if protein tumbling is prevented, but the isotropy required for high-resolution solution NMR is then lost. However, if the immobilized protein molecule
Thermally driven rotational and translational diffusion of proteins and other biomolecules is governed by frictional coupling to their solvent environment. Prediction of this coupling from biomolecular structures is a longstanding biophysical problem, which cannot be solved without knowledge of water dynamics in an interfacial region comparable to the dry protein in volume. Efficient algorithms ha
Loss of immune function and an increased incidence of myeloid leukemia are two of the most clinically significant consequences of aging of the hematopoietic system. To better understand the mechanisms underlying hematopoietic aging, we evaluated the cell intrinsic functional and molecular properties of highly purified long-term hematopoietic stem cells (LT-HSCs) from young and old mice. We found t
The Amazon rainforests and their biological diversity are being lost rapidly by the onslaught of extractive industries, large-scale agriculture and infrastructure development, which also undermines the integrity of indigenous territories and ethnicities, threatening the tremendous cultural diversity of the Amazon. The loss of forest, the disintegration of local communities and the increase of the
Vi vill med den här artikeln peka på att Sveriges städer har flera utmaningar kring styrning och hantering av vatten, samt föreslår sju principer för lösningar. Klimatförändringarna och den urbana tillväxten gör att åtgärder behövs nu för att hantera både vattenbrist och översvämning på ett integrerat sätt. Här fokuserar vi på kommunnivå och urbana områden, där vi argumenterar för att det behövs eWe argue in this paper that Swedish urban areas have several urgent challenges when it comes to water governance and we propose seven principles for addressing them. Climate change and urban growth call for swift action to manage both water scarcity and flooding in an integrated way. This paper focuses on the municipal level for which we argue that there is a need for a more systematic approach. T
Application of concurrent engineering (CE) to machinery has to consider the type of production (individual, serial), product complexity and level of design. Product development (PD) involves four characteristic levels of design that requires specific activities. The characteristic design levels require definitions of the activities for providing the necessary software and other support for all pha
Aims/hypothesis: Preterm birth (gestational age <37 weeks) has been associated with insulin resistance early in life. However, no large population-based studies have examined risks of type 1 and type 2 diabetes and potential sex-specific differences from childhood into adulthood. Clinicians will increasingly encounter adults who were born prematurely and will need to understand their long-term ris
One aspect of tombs and burials in the BA Aegean in general that has not received much notice is that of color (hue and shine). Were certain hues more predominant than others? Was this significant? Was the presence (or absence) of shine of importance? Following a discussion of ‘what is color?’, the study and results of the colors of the finds from Late Bronze Age tombs at three sites in the Greek
I den dystopiska skildringen Enhet (2006) gestaltar Ninni Holmqvist ett alternativt svenskt samhälle där människor som inte är samhällsnyttiga används som biologiskt reservmaterial för att bota sjukdomar hos andra, behövda människor. Samhället har blivit totalitärt, människor bedöms efter produktivitet och organdonation har blivit ett tvång för vissa grupper. I den här artikeln diskuterar jag hur
