High resolution autoradiography of [F]MK-6240 and [F]Flortaucipir shows similar neurofibrillary tangle binding patterns preferentially recognizing middling neurofibrillary tangle maturity.

Recent developments in tau positron emission tomography (PET) radiotracers have enhanced the visualization of tau aggregates in Alzheimer's disease (AD). The maturity level of neurofibrillary tangles can affect its recognition by biomarkers. Early detection of tau aggregates regarding tangle pathology is of interest in early diagnosis and comparison of tau radiotracers in this aspect is important.

gen. nov.: The complex.

is proposed as a new genus in Family Marasmiaceae to accommodate a small group of six species morphologically resembling or but molecularly distinct from both genera. Newly described taxa include , , and f. ; species epithets transferred are , , .

Is segmentectomy potentially adequate for clinical stage IA3 non-small cell lung cancer.

Objectives: This study aims to identify the feasibility of segmentectomy for clinical stage IA3 (cIA3) vs cIA1-2 non-small cell lung cancer (NSCLC).

Methods: We retrospectively analysed data of consecutive patients with segmentectomy for cIA NSCLC across three centres between January 2017 and December 2022. The stabilized inverse probability of treatment-weighting (IPTW) was employed to minimize potential confounding in baseline characteristics.

Mayo Normative Studies: regression-based normative data for remote self-administration of the Stricker Learning Span, Symbols Test, and Mayo Test Drive Screening Battery Composite and validation in individuals with mild cognitive impairment and dementia.

Few normative data for unsupervised, remotely-administered computerized cognitive measures are available. We examined variables to include in normative models for Mayo Test Drive (MTD, a multi-device remote cognitive assessment platform) measures, developed normative data, and validated the norms. 1240 Cognitively Unimpaired (CU) adults ages 32-100 years (96% White) from the Mayo Clinic Study of Aging and Mayo Alzheimer's Disease Research Center with Clinical Dementia Rating of 0 were included.
