Att den fria världen avbryter sina diplomatiska relationer med Irans totalitära regim är avgörande för att begränsa islamiska regimens terror och flyktingsspionage, skriver Arvin Khoshnood och Ardavan Khoshnood, Irankännare.The free world's severance of diplomatic relations with Iran's totalitarian regime is crucial to curbing the Islamic regime's terror and espionage, write Arvin Khoshnood and Ardavan Khoshnood, Iran experts.
Hur påverkas synergonomin av att jobba vid fler och stora skärmar? Det ska Hillevi Hemphälä, doktor i arbetsmiljöteknik, undersöka i en treårig forskningsstudie.– Enligt de gamla rekommendationerna ska datorskärmar på upp till 26 tums storlek placeras på 90 centimeters avstånd för att vi ska undvika huvudrörelser i sid- och höjdled. Men många skrivbord i dag är 80 centimeter och datorskärmarna of
Affibody molecules constitute a class of small (7 kDa) scaffold proteins that can be engineered to have excellent tumor targeting properties. High reabsorption in kidneys complicates development of affibody molecules for radionuclide therapy. In this study, we evaluated the influence of the composition of cysteine-containing C-terminal peptide-based chelators on the biodistribution and renal reten
Affibody molecules, small (7 kDa) scaffold proteins, are a promising class of probes for radionuclide molecular imaging. Radiolabeling of Affibody molecules with the positron-emitting nuclide 68Ga would permit the use of positron emission tomography (PET), providing better resolution, sensitivity, and quantification accuracy than single-photon emission computed tomography (SPECT). The synthetic an
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.

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
