Background: The 2018 Alzheimer's Disease Facts and Figures special report includes two new guidelines for measuring dementia symptoms. The first requires that a biomarker (biological factor) be added to a doctor's clinical judgment of the cause of symptoms when determining whether dementia is present. The second involves identifying four stages of dementia: normal cognition, preclinical, MCI and dementia. Now only those with defining brain pathologies and significant symptoms will be judged to be persons with stage [...]

Background: Fluorescence In Situ Hybridization (FISH) has become routine for bio-medical research and medical diagnosis, thereby offering a variety of probes and ready-to-use kits that fulfil requirements for many applications. However, conventional FISH relies on chemical and/or thermal denaturation to improve target accessibility and uses huge amounts of DNA that needs to be bonded to the target site. COMBinatorial Oligo-nucleotide FISH (COMBO-FISH) offers possibilities to circumvent these shortcomings. Methods: [...]

Studies in the field of neuroscience have shown that the neural network responsible for numeracy overlaps with the visual and spatial processing regions. Other studies in psychology also highlighted an association of visual-spatial processing with mathematical competence at the early stages of development. These findings suggest that research on the size of the focal area of attention (consciousness) can contribute to understanding the development of numeracy. In this case study, we verified the hypothesis of devel [...]

The ability to successfully transplant cells and organs from a donor into an immunologically disparate recipient is one of the greatest treatment advances in the history of medicine. Nevertheless, acute and chronic rejection, graft versus host disease, and the inability to identify suitable donors continue to be challenges and limit broader application of cell and organ transplantation to the many patients that could benefit. Immunosuppression before and after allogeneic transplant has been found to dramatically im [...]

Although tissue stem cells are essential for the maintenance, renewal, and repair of vertebrate organs and tissues, previously, the simple act of counting them has not been possible. For more than a half-century, progress in tissue stem cell research and medicine has been undermined by the lack of a means to determine tissue stem cell number. In particular, a major unmet need for stem cell transplantation medicine has been a way to quantify the specific dosage of tissue stem cell treatments. The counting problem pe [...]

Background: One of the goals of clinical islet transplantation is to achieve a single-donor transplant that is dependent on obtaining enough quality β cell mass from one donor pancreas. Human islets are routinely cultured prior to transplantation, and pro-survival factors such as GLP-1 analogues have been reported to maintain β cell mass and survival. Interestingly, human islets may secrete GLP-1 and they also express the enzyme DPP4 that proteolytically cleaves GLP-1 into an inactive form. The aim of [...]
