Platelet-derived growth factor receptor β (PDGFRβ) is a transmembrane tyrosine kinase receptor involved, for example, in angiogenesis. Overexpression and excessive signaling of PDGFRβ has been observed in multiple malignant tumors and fibrotic diseases, making this receptor a pharmaceutical target for monoclonal antibodies and tyrosine kinase inhibitors. Successful targeted therapy requires identi

PURPOSE: Human epidermal growth factor receptor type 3 (HER3) is a transmembrane receptor tyrosine kinase belonging to the HER (ErbB) receptor family. Membranous expression of HER3 is associated with trastuzumab resistance in breast cancer and the transition to androgen independence in prostate cancer. Imaging of HER3 expression in malignant tumors may provide important diagnostic information that

UNLABELLED: Affibody molecules are small (7 kDa) nonimmunoglobulin scaffold proteins with favorable tumor-targeting properties. Studies concerning the influence of chelators on biodistribution of (99m)Tc-labeled Affibody molecules demonstrated that the variant with a C-terminal glycyl-glycyl-glycyl-cysteine peptide-based chelator (designated ZHER2:V2) has the best biodistribution profile in vivo a

Affibody molecules are a class of affinity agents for molecular imaging based on a non-immunoglobulin protein scaffold. Previous studies have demonstrated high contrast for in vivo imaging of cancer-associated molecular abnormalities using Affibody molecules. Using the radionuclide (18)F for labeling and PET as the imaging modality, the sensitivity of molecular imaging using Affibody molecules can

Affibody molecules are a class of small (7 kDa) non-immunoglobulin scaffold-based affinity proteins, which have demonstrated substantial potential as probes for radionuclide molecular imaging. The use of positron emission tomography (PET) would further increase the resolution and quantification accuracy of Affibody-based imaging. The rapid in vivo kinetics of Affibody molecules permit the use of t

Accurate detection of cancer-associated molecular abnormalities in tumors could make cancer treatment more personalized. Affibody molecules enable high contrast imaging of tumor-associated protein expression shortly after injection. The use of the generator-produced positron-emitting radionuclide (68)Ga should increase sensitivity of HER2 imaging. The chemical nature of radionuclides and chelators

Engineered affibody molecules can be used for high contrast in vivo molecular imaging. Extending a recombinantly produced HER2 binding affibody molecule with a hexa-histidine tag allows for convenient purification by immobilized metal-ion affinity chromatography and labeling with [(99m)Tc(CO)3](+) but increases radioactivity uptake in the liver. To investigate the impact of charge, lipophilicity,

PURPOSE: Radionuclide imaging of insulin-like growth factor type 1 receptor (IGF-1R) expression in tumours might be used for selection of patients who would benefit from IGF-1R-targeted therapy. We have previously shown the feasibility of IGF-1R imaging using the Affibody molecule (111)In-DOTA-His(6)-Z(IGF1R:4551). The use of (99m)Tc instead of (111)In should improve sensitivity and resolution of

Affibody molecules are a class of affinity proteins. Their small size (7 kDa) in combination with the high (subnanomolar) affinity for a number of cancer-associated molecular targets makes them suitable for molecular imaging. Earlier studies demonstrated that the selection of radionuclide and chelator may substantially influence the tumor-targeting properties of affibody molecules. Moreover, the p

Chemicals is the industrial sector with the highest energy demand, using a substantial share of global fossil energy and emitting increasing amounts of greenhouse gasses following rapid growth over the past 25 years. Emissions associated with energy use have increased with growth in coal-dependent regions but are also commonly underestimated in regions with higher shares of renewable energy. Renew

In 2016, the Norwegian government initiated an extensive reform of the regional scale, eventually reducing the number of political-administrative counties from nineteen to eleven through mergers. The territorial and institutional changes that followed can be understood as a partial regional (de/re)institutionalisation process, in which the political and administrative boundaries of the merged coun

Abstract på spanskaUna de las fuentes más sólidas de nuevo conocimiento sobre las categorías tipológicas proviene de nuestro creciente entendimiento de las lenguas indígenas de América del Sur, una región que hasta hace poco ha estado significativamente subrepresentada en los estudios tipológicos. Este artículo ofrece un ejemplo a través de la investigación del número en nadëb, un miembro de la peOne of the most robust sources of fresh insights into typological categories comes from our growing knowledge of the indigenous languages of South America, a region that until recently has been significantly under-represented in typological studies. This paper offers a case in point through the investigation of number in Nadëb, a member of the small Naduhup family of the northwest Amazon, which re

Nominal classification is a robust feature in many Amazonian languages, and aspects of these systems offer significant challenges to our broader conception of the phenomenon. Yet a clear characterization of Amazonian classification systems must be firmly grounded in detailed descriptive analysis on one hand, and in a principled definition of classification as a typological category on the other –

Not all spatial adjuncts behave alike. In some languages, certain spatial adjuncts display different marking or different combinatorial possibilities than others. Recent functional-typological studies make two claims about this differential place marking phenomenon: (1) it is primarily motivated by noun semantics, opposing place names and other nouns; and (2) it is primarily realized as a contrast

Levinson (2003) provides evidence that distinct cultures display distinct spatial references that, as a consequence, impacts the linguistic encoding of spatial notions. This linguistic variation has fostered the interest of understanding the spatial domains responsible for the linguistic encoding of spatial information. According to Levinson and Wilkins (2006, p. 2), these domains consist in: the

Abstract in Portuguese:Referências a paisagens e lugares são elementos centrais nas narrativas tradicionais de falantes da língua Dâw (Naduhup,Amazônia brasileira).

This emphasis on spatial reference is primarily established through locative adverbial clauses that are often repeated throughout the discourse. Their function is to relate an event to a place, establish reference to locative information mentioned earlier in discourse, and provi

Abstract på portugisiska As línguas diferem umas das outras em relação a se, e, como, elas categorizam nomes a partir de critérios lexicais e gramaticais específicos. Um exemplo bastante estudado é a distinção entre nomes contáveis e massivos, que divide os nomes de acordo com sua capacidade de serem contados ou medidos. Comparações entre as línguas sobre esse sistema de categorização nominal mostLanguages differ with respect to if and how they categorize their nouns based on specific lexical or grammatical criteria. A well-studied example is the mass/count distinction, which groups nouns according to their ability to be counted or measured. Cross-linguistic comparison on this noun-categorization system provided evidence that the mass/count distinction is not a reflection of pre-linguistic
