Astrogen Co Ltd. has disclosed prodrugs of 5-aminolevulinic acid (5-ALA) derivatives acting as fluorescence imaging agents and photosensitizers in photodynamic therapy with improved storage stability, reported to be useful for diagnosis and treatment of cancer, aging, alopecia, insomnia, inflammatory and metabolic disorders.
Prostate cancer is still one of the main causes of cancer death among men; while prostate-specific antigen (PSA) testing is done for screening, there are recommendations against its use due to its nonspecific and suboptimal results. There is thus an urgent need for new biomarkers that are more accurate in the detection of prostate cancer.
Curently the only available blood test to tell which women are at risk of postpartum depression (PPD) is the one that confirms their pregnancy – and a one in seven chance of developing the condition which can have long-term implications for both mother and child. Research out of the University of Virginia and Weill Cornell Medicine could soon change that by identifying biomarkers in the third trimester of pregnancy that indicate which women have the greatest risk of developing PPD.
Researchers from Massachusetts General Hospital and affiliated organizations have published preclinical data for [18F]CNL-02, a positron emission tomography (PET) radioligand targeting mitochondrial complex I (MC-I) that is being developed for the diagnosis of Alzheimer’s disease and other neurodegenerative disorders.
Researchers from Astrazeneca plc and Karolinska Institutet have described the positron emission tomography (PET) evaluation of [11C]AZD-2423, a chemokine receptor type 2 (CCR2) radioligand in non-human primate (NHP) brain imaging. CCR2 is essential in immune cell migration control. It is mainly expressed in microglia and monocytes and closely linked to the brain’s immune defense.
Mesenchymal-epithelial transition factor (MET) plays a relevant role in growth, survival, migration and tissue repair. Alterations in MET have been found in non-small-cell lung cancer and head and neck cancer, and are associated with aggressive and difficult-to-treat cancer types.
Fourteen global pharma companies are getting together to conduct the largest proteomics study to date, analyzing 600,000 blood samples held in the UK Biobank to assess the levels of 5,400 different proteins.
Work at Beijing Normal University and affiliated organizations has led to the discovery and preclinical characterization of a novel tau-PET radiotracer for Alzheimer’s disease (AD).
Artificial intelligence (AI)-based models developed by a team of international researchers were able to identify ovarian cancer in ultrasound images more accurately than humans. Results from a study published in Nature Medicine showed that the AI models achieved an accuracy rate of 86.3%, compared to 82.6% for the experts and 77.7% for the non-expert examiners.
In a recently published study, researchers from the University of Pennsylvania and collaborators aimed to identify compounds with high affinity to α-synuclein aggregates and high selectivity toward pathological α-synuclein compared to other brain targets.
