Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and othe
Tack vare ett näst intill oändligt antal variationer så har proteiner blivit naturens standardlösning för diverse uppgifter och problem. I våra egna kroppar har vi en uppsjö av olika varianter där några är allmänt välkända, t.ex. hemoglobin i våra röda blodkroppar som transporterar runt syre och insulin vilket sänker vår blodsockernivå. Andra proteiner är mer okända men trots det lika viktiga, exeThe behavior of concentrated protein solutions is of general high interest due to implications in, for example, biological systems and medical applications. It is necessary to investigate the rheological properties of such systems to understand how parameters, such as stability, are affected by the high concentrations. Unfortunately, studies are often hindered by the lack of sufficient quantities
The impact of the microbiota on our health is rapidly gaining interest. While several bacteria have been associated with disease, and others being indicated as having a probiotic effect, the individual biomolecules behind these alterations are often not known. A major problem in the study of these factors in vivo is their low abundance in complex environments. We recently identified the first secr
Cloud computing has become a compelling paradigm built on compute and storage virtualization technologies. The current virtualization solution in the Cloud widely relies on hypervisor-based technologies. Given the recent booming of the container ecosystem, the container-based virtualization starts receiving more attention for being a promising alternative. Although the container technologies are g
BACKGROUND: Platelets are a critical element in coagulation and inflammation, and activated platelets are linked to cancer risk through diverse mechanisms. However, a causal relationship between platelets and risk of lung cancer remains unclear. METHODS: We performed single and combined multiple instrumental variable Mendelian randomization analysis by an inverse-weighted method, in addition to a
Preclinical studies support an anticancer effect of statin drugs, yet epidemiologic evidence remains inconsistent regarding their role in breast cancer primary prevention. Here, we report an updated analysis of the association between statin use and breast cancer incidence in the Nurses' Health Study (NHS) cohort. Postmenopausal NHS participants without a cancer history were followed from 2000 unt
Today, commercially used brasses commonly contain 2 to 4 wt.% lead. As the availability of low-lead and lead-freebrass increase, there are environmental incentives for investigating the consequences of replacing thelead-containing brasses with lead-free equivalents. Generally, lead-free brass is expected to have a lowermachinability than its lead-alloyed counterpart, implying a higher manufacturin
This chapter presents an assessment of green house performance (GHG) performance of current and prospective Swedish ethanol production and outlines a strategy for improving the GHG performance on an expanding ethanol market. Calculations are presented that consider process integration and establishment of biocombines producing multiple products, the use of a broader resource base including lignoce
Secret diplomacy may at first glance appear to be the antinomy of public diplomacy. Diplomats have traditionally been discouraged from participation in the domestic or foreign politics of the state in which they exercise their functions, and their official communications are, according to Articles 12 and 13 of the Havana Convention (1928), to be channelled through the host Foreign Ministry. By con
Proteins of the signal crayfish Pacifastacus leniusculus egg and spermatophore were identified using in-gel digestion, mass spectrometry, and Mascot search. Forty-one and one-hundred-fifty proteins were identified in egg and spermatophore, respectively. The proteins were classified into nine categories including cell defence, cell signaling, cytoskeleton, DNA related activity, metabolism and energ
The intestinal mucosa is exposed to large amounts of foreign antigen (Ag) derived from commensal bacteria, dietary Ags, and intestinal pathogens. Dendritic cells (DCs) are believed to be involved in the induction of tolerance to harmless Ags and in mounting protective immune responses to pathogens and, as such, to play key roles in regulating intestinal immune homeostasis. The characterization of

It has long been recognised that nitric oxide (NO) and nitrogen dioxide (NO2) can promote the oxidation of methane and other hydrocarbons under various fuel-lean and fuel-rich conditions and a range of temperatures and pressures conditions. However, despite the ease with which NO and NO2 interconvert under the oxidation conditions, the reactions responsible for initiating the oxidation process for
An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI
Antibody-based microarrays is a rapidly evolving technology that has gone from the first proof-of-concept studies to more demanding proteome profiling applications, during the last years. Miniaturized microarrays can be printed with large number of antibodies harbouring predetermined specificities, capable of targeting high- as well as low-abundant analytes in complex, nonfractionated proteomes. C
This study examines innate immunity to oral Salmonella during primary infection and after secondary challenge of immune mice. Splenic NK and NKT cells plummeted early after primary infection, while neutrophils and macrophages (M{phi}) increased 10- and 3-fold, respectively. In contrast, immune animals had only a modest reduction in NK cells, no loss of NKT cells, and a slight increase in phagocyte
Sequence-dependent coordination of alkali ions to the nucleotide bases in the minor groove of AT-tract B-DNA has recently been inferred from X-ray crystallography, solution NMR and computer simulations. Here, we present new Na-23 and Rb-87 magnetic relaxation dispersion (MRD) data that demonstrate competitive and long-lived binding of Na+ and Rb+ ions in the minor groove of the B-DNA duplex [d(CGC
