Electrical Impedance Myography Detects Disease Progression over 12 to 24 Months in Facioscapulohumeral Muscular Dystrophy

Annals of Neurology, EarlyView.
Objective Targeted therapies for facioscapulohumeral muscular dystrophy (FSHD) are progressing through clinical trials. Electrical impedance myography (EIM) provides a noninvasive biomarker of muscle composition that may be valuable especially in early phase trials. This study evaluated EIM data from a multicenter FSHD cohort over 24 months.

Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

Annals of Neurology, EarlyView.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

Multimorbidity and Associations with Cognition and Alzheimer's Disease Biomarkers

Annals of Neurology, EarlyView.
Objective Multimorbidity, the coexistence of 2 or more chronic conditions, has been linked to cognitive aging and Alzheimer's disease (AD) and AD‐related dementias, yet the mechanisms remain unclear. We aimed to examine the associations of multimorbidity with cognition and biomarkers across multiple mechanistic pathways.

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Dr. Hans Kohn and the political takeover of the Berlin Medical Society by the National Socialist regime in 1933

The Anatomical Record, EarlyView.
Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.
