With the development of new radiopharmaceutical therapies, quantitative SPECT/CT has progressively emerged as a crucial tool for dosimetry. One major obstacle of SPECT is its poor resolution, which results in blurring of the activity distribution. Especially for small objects, this so-called partial-volume effect limits the accuracy of activity quantification. Numerous methods for partial-volume c
Interfacial structures on the nanoscale are crucial for a wide field of applications ranging from biological membranes in life sciences through organic solar cells and industrial coatings in soft matter to hard matter structures. The latter include thin film coatings and materials such as magnetic nanoparticles and topological structures like magnetic skyrmions. Advancing such application rests on
A major challenge hampering the industrial and biological exploitation of lipases is the self-limiting effect of the lipolytic reaction. Defying sustained attention throughout history, the influence of lipase catalysed lipolysis on the internal structure of thin triglyceride films has proved elusive. An in-depth understanding of the lipolysis process at the triglycerides/aqueous interface will ass
The structure and function of many proteins are regulated post-translationally through glycan attachment. These glycans, assembled via competing enzymatic reactions, generate diverse glycoform populations - variants sharing a protein backbone but differing in glycan structures. While current analyses often focus on individual glycoforms, we demonstrate that population-level glycoform analysis - in
Polycyclic aromatic hydrocarbons (PAHs) of molecular mass (MM) 302 Da comprise numerous structural isomers that are of high concern for human health. Because of their multiplicity, low abundance in the environment, and limited availability of authentic standards, their occurrence, composition, and environmental health risk remain not well characterized. Here we extend the characterization of MM 30
PURPOSE: Leukemic stem cells (LSCs) may harbor important resistance to tyrosine kinase inhibitors in chronic myeloid leukemia (CML). We identified Philadelphia chromosome (Ph) positive CD34+CD38- bone marrow cells (here denoted LSCs) and addressed their response-predictive value in CML patients (n=48) subjected to nilotinib in the ENEST1st trial (NCT01061177).EXPERIMENTAL DESIGN: Two flow cytometr
Chromosome banding analyses reveal secondary chromosome abnormalities in addition to the MYC translocations t(8;14)(q24;q32), t(8;22)(q24;q11), and t(2;8)(p11;q24) in 60%-80% of Burkitt lymphomas/leukemias (BL). The high incidence of such aberrations indicates that additional changes are important, perhaps necessary, for malignant transformation, i.e., the 8q24/MYC rearrangements may not be suffic
Phagocytosis is relevant for many research fields and is often measured as a functional outcome. However, accurate quantification can be challenging, and many researchers find it difficult to study in a robust manner. There are many ways to measure phagocytosis, but what is often overlooked is the importance of experimental design and how the analysis is planned and performed. Experimental factors
Antibody binding to bacterial surfaces plays a crucial role in immunity, and a key characteristic of this protein-protein interaction is the binding affinity. Determining the affinity of an antibody binding to its antigen is the first step in predicting the function in a physiological environment where other competing protein interactions may be present. Antibody-antigen affinity is often evaluate
Background: Current evidence supports the use of intravenous thrombolysis with alteplase in patients with wake-up stroke selected with MRI or perfusion imaging and is recommended in clinical guidelines. However, access to advanced imaging techniques is often scarce. We aimed to determine whether thrombolytic treatment with intravenous tenecteplase given within 4·5 h of awakening improves functiona

BRAF and NRAS mutations are frequently found in melanoma tumours and recently developed BRAF targeted therapies demonstrate significant clinical benefit.
Patients with ductal carcinoma-in-situ (DCIS) are currently not prescribed adjuvant systemic treatment after surgery and radiotherapy. Prediction of DCIS patients who would benefit from radiotherapy is warranted. Statins have been suggested to exert radio-sensitizing effects. The target for cholesterol-lowering statins is HMG-CoA reductase (HMGCR), the rate-limiting enzyme in the mevalonate pathwa
Androgen signalling through the androgen receptor (AR) is essential for prostate cancer initiation, progression and transformation to the lethal castration-resistant state. The aim of this study was to characterize the mechanisms by which miR-145 deregulation contribute to prostate cancer progression. The miR-145 levels, measured by quantitative reverse transcription-polymerase chain reaction, wer
Early detection of prostate cancer (PC) using prostate-specific antigen (PSA) in blood reduces PC-death among unscreened men. However, due to modest specificity of PSA at commonly used cut-offs, there are urgent needs for additional biomarkers contributing enhanced risk classification among men with modestly elevated PSA.
Factors affecting serum prostate-specific antigen (PSA) levels in men are clinically important, but apart from effects mediated through the androgen receptor, they are poorly understood.
Infantile malignant osteopetrosis (IMO) is a rare, lethal, autosomal recessive disorder characterized by non-functional osteoclasts. More than 50% of the patients have mutations in the TCIRG1 gene, encoding for a subunit of the osteoclast proton pump. The aim of this study was to restore the resorptive function of IMO osteoclasts by lentiviral mediated gene transfer of the TCIRG1 cDNA. CD34(+) cel
We randomised 46 newly diagnosed patients with chronic myeloid leukaemia (median age 56) to receive dasatinib 100mg QD or imatinib 400mg QD and report outcome as an intention-to-treat analysis with 36months follow-up. Early cytogenetic and molecular responses were superior in the dasatinib group, with a tendency that imatinib patients caught up with time. For instance, MR3.0 was reached at 3months
Background:The microRNA, miR-34c, is a well-established regulator of tumour suppression. It is downregulated in most forms of cancers and inhibits malignant growth by repressing genes involved in processes such as proliferation, anti-apoptosis, stemness, and migration. We have previously reported downregulation and tumour suppressive properties for miR-34c in prostate cancer (PCa).Methods:In this
