Biodistribution and dosimetry of the PET radioligand [F]CHDI-650 in mice for detection of mutant huntingtin aggregates.

Background: Huntington's disease (HD) is a rare neurodegenerative disorder caused by an expansion of the CAG trinucleotide repeat in the huntingtin gene which encodes the mutant huntingtin protein (mHTT) that is associated with HD-related neuropathophysiology. Noninvasive visualization of mHTT aggregates in the brain, with positron emission tomography (PET), will allow to reliably evaluate the efficacy of therapeutic interventions in HD. This study aimed to assess the radiation burden of [F]CHDI-650, a novel fluorinated mHTT radioligand, in humans based on both in vivo and ex vivo biodistribution in mice and subsequent determination of dosimetry for dosing in humans.

Preclinical validation and kinetic modelling of the SV2A PET ligand [F]UCB-J in mice.

Synaptic vesicle protein 2A (SV2A) is ubiquitously expressed in presynaptic terminals where it functions as a neurotransmission regulator protein. Synaptopathy has been reported during healthy ageing and in a variety of neurodegenerative diseases. Positron emission tomography (PET) imaging of SV2A can be used to evaluate synaptic density.

Link Between Metabolic Syndrome, Blood Lipid Markers, Dietary Lipids, and Survival in Women with Early-Stage Breast Cancer.

Background/objectives: Nearly 10% of cancers could be prevented through dietary changes. In addition, breast cancer (BC) is the most common cancer in women worldwide. Inadequate diet may lead to several metabolic abnormalities, including metabolic syndrome (MS).

Considerations for Severe Acute Respiratory Syndrome Coronavirus 2 Genomic Surveillance: A Joint Consensus Recommendation of the Association for Molecular Pathology and Association of Public Health Laboratories.

Next-generation sequencing (NGS) has applications in research, epidemiology, oncology, and infectious disease diagnostics. Wide variability exists in NGS wet laboratory techniques and dry laboratory analytical considerations. Thus, many questions remain unanswered when NGS methods are implemented in laboratories for infectious disease testing.
