We have used a human tumor nude mouse model involving heterotransplantation and serial passage of an estrogen receptor (ER) positive, progesterone receptor (PgR) negative human endometrial adenocarcinoma. The effects of estradiol treatment on tumor growth, ER activation and PgR induction were investigated two and four years after heterotransplantation. In Experiment I, two years after initial hete
Essentially pure orthorhombic M1 and pseudo-hexagonal M2 phases were prepared using the precursor method. Consistent with literature the M1 phase was shown to be effective for propane ammoxidation to acrylonitrile while the M2 phase was essentially inert for propane activation. Both phases convert propene efficiently to acrylonitrile. Both phases show a significant selectivity dependence on the am
This study, which is the first and main part of a two-volume work, is concerned with the history and philology of original and translated works Adversus Iudaeos circulating among the Eastern Slavs from the baptism of Rus' c.988 till the early 16th century. Excluded is the literature of Lithuanian Ruthenia from the 14th century onwards. On the material of 11–15th-century MSS the dissemination of th
A discussion of the character and qualities of the object as a sculptural cathegory in contemorary art.
Popular Abstract in Swedish In conclusion we show that basement membrane components are present in cartilage ECM and that they may serve roles both as BM functional equivalents as well as organizational roles during ECM formation. Den extracellulära matrixen (ECM) är ett nätverk av makromolekyler som, tillsammans med celler, bildar de olika vävnaderna I alla organismer från phylum metazoa. Till sThe extracellular matrix (ECM) is a network of macromolecules which, together with cells, forms the various tissues of all metazoan organisms. Cartilage, in contrast to most other tissues, contains relatively few cells in proportion to the volume occupied by ECM. Part of this work involves investigation of cartilage ECM for expression and secretion of proteins that are considered to be the definin
A polymorphism in the coding region of the human cystatin D gene has been detected by direct sequencing of amplified DNA from different individuals. The variation, resulting from a T/C transition in exon 1 of the gene, causes an amino acid variation, Cys/Arg, at the protein level. An allele-specific oligonucleotide hybridization assay was developed and used to demonstrate this polymorphism in the
A monodispersive aerosol dynamic model, coupled to a 3D hydrodynamical grid model, has been used to study the dynamics of ultrafine particles inside a road tunnel in Stockholm, Sweden. The model results were compared to measured data of particle number concentrations, traffic intensity and tunnel ventilation rate. Coagulation and depositional losses to the tunnel walls were shown to be important p
Little is known about the fuel stores that arctic-breeding waders put on before departure from the breeding grounds. During a ship-based expedition to arctic Canada, we caught waders at seven, mainly coastal sites, within 68degrees-76degreesN and 139degrees-67degreesW, from 28 July to 31 August 1999. More than two hundred waders of twelve species were trapped, mainly White-rumped Calidris fuscicol
The nuclear magnetic shielding tensor is a sensitive probe of the local electronic environment, providing information about molecular structure and intermolecular interactions. The magnetic shielding tensor of the water proton has been determined in hexagonal ice, but in liquid water, where the tensor is isotropically averaged by rapid molecular tumbling, only the trace of the tensor has been meas
The article analyses the compulsory care of drug misusers in Sweden. An historical analysis of this field of work as a part of the Swedish welfare state highlights historically changing legislations, institutions, understandings and practices. Following Foucault, it is argued that it is impossible to distinguish between power and care and that confusion about coercive care is a result of not ackno
In this paper, we propose a simple and intuitive way to predict self-assembled island sizes for varying deposition conditions, i.e., temperature and deposition rate. The average island size and the modality of the size distribution (unimodal with large or small islands, or bimodal) is calculated via materials balancing over a total island density (known by experiments or from nucleation calculatio
Mechanisms responsible for the decrease in shortening velocity after prolonged contraction ("latch" state) were investigated at identical force during early (20 s, "phasic") and sustained (5 min, "tonic") phases of high-K+ (25-30 mM) contractions in smooth muscle of guinea pig taenia coli. Cytoplasmic Ca2+ concentration, myosin light-chain phosphorylation, and maximum shortening velocity all decli
The major part of this work deals with a new method for quantification of VOCs in concrete. There is a need for this type of quantification due to the development in cement and concrete production using plasticizing agents and fillers for improved rheological properties, and alternative fuels and waste materials to reduce the environmental impact of cement production. Measurements are needed to sh
The phosphido-bridged cluster [Os6(µ-H)(CO)22(µ-PH2)] and the corresponding phosphinidene-bridged cluster [Os6(µ-H)2(CO)21(µ-PH)] have been prepared from the reaction of [Os3(CO)11(PH3)] with [Os3(CO)11(NCMe)] in toluene. In a similar reaction, [Os6(µ-H)(CO)21(NCMe)(µ-PH2)] has been prepared from the reaction of [Os3(CO)11(PH3)] with [Os3(CO)10(NCMe)2]. The two Os6 clusters have been fully charact
