The stable isotope of carbon, 13C, has been used in several studies for source characterization of carbonaceous aerosol since there are specific signatures for different sources. In rural areas, the influence of different sources is complex and the application of δ13C for source characterization of the total carbonaceous aerosol (TC) can therefore be difficult, especially the separation between bi
Secondary organic aerosol (SOA) plays a significant role in climate change by altering the global atmospheric radiation budget. Biogenic volatile organic compounds (BVOCs) are major sources for the formation of SOA. Their relationship is critical to understand the continental biosphere-aerosol-cloud-climate (COBACC) feedback mechanism but receives less attention in previous studies. In this study,
Ytan av alla celler är dekorerad med kolhydrater som står för mycket av den information en cell överför till omgivande celler. Många av kolhydraterna tillhör en föreningsklass som kallas proteoglykaner som består av ett protein sammanbundet med en eller flera långa kolhydratkedjor. Dessa kolhydratkedjor kallas glykosaminoglykaner och är bundna till proteinet via kolhydraten xylos. Än så länge har β-1,4-Galactosyltransferase 7 (β4GalT7) is a key enzyme in the biosynthesis of proteoglycans (PGs) and glycosaminoglycan (GAG) chains, which are important macromolecules involved in many biological processes such as cell growth and cell signaling as well as in cancer pathobiology and viral and bacterial infections. Despite its pivotal role, much is still unknown regarding the specific structure of
Adipose tissue plays a major role in regulating whole-body energy metabolism. While the biochemical processes regulating storage and release of excess energy are well known, the temporal organization of these events is much less defined. In this study, we have characterized the presence of small surface-associated lipid droplets, distinct from the central droplet, in primary human adipocytes. Base

Visible Multifilter Rotating Shadowband Radiometer (vis-MFRSR) data were collected at Storm Peak Laboratory (SPL), a mountain-top facility in northwest Colorado, from 1999 to 2011 and in 2013. From 2011 to 2014, in situ measurements of aerosol light scattering were also obtained. Using these data sets together, the seasonal impact of dust and biomass burning is considered for the western USA. Anal
Cancer of unknown primary (CUP) is diagnosed at a metastatic stage, conferring an unfavorable prognosis. The natural history of the disease is poorly understood, which complicates diagnosis, treatment and follow-up. Population-based survival data are lacking regarding location and histology of metastases. From the Swedish Cancer Registry, 18 911 CUP patients were identified between years 1987 and
A fluvial sequence near Cave Stream (north of Castle Hill Village, central Canterbury), New Zealand, contains organically-preserved plant macrofossils (cuticles). The almost ubiquitous presence of Araucariaceae macrofossils in the lower part of the section and their stratigraphic disappearance roughly coincident with the appearance of the angiosperm leaf Dryandra comptoniaefolia and conifer taxa o
The transient electromagnetic (TEM) method is widely used in resistivity mapping but rarely applied in monitoring experiments. In this study, we present an algorithm to invert time-lapse TEM data, with inversion of both synthetic data and field data. Three main novelties distinguish this new inversion algorithm: i) a multiple-mesh approach is used for the definition of model parameters and forward
Southern travelling habits were recorded for 127 melanoma patients from southern parts of Sweden (the 56th latitude), 55 thyroid cancer patients, 100 non-Hodgkin's patients and 794 healthy controls from the same region. Melanoma patients were found to travel significantly more often south of the 45th latitude, as compared with patients with non-Hodgkin's lymphoma or thyroid carcinoma (RR = 2.2 for
