Fibril fragmentation in amyloid assembly and cytotoxicity: When size matters [PDF]
Amyloid assemblies are associated with several debilitating human disorders. Understanding the intra- and extracellular assembly of normally soluble proteins and peptides into amyloid aggregates and how they disrupt normal cellular functions is therefore

Even though it is currently well-established that α-synuclein aggregation is closely associated with the pathological events in Parkinson’s disease (PD) and several other neurodegenerative disorders, collectively called synucleinopathies, the mechanistic

Is This Atrial Fibrillation? [PDF]
A 19‐year‐old girl was referred to our cardiology department for catheter ablation (isolation of the pulmonary veins) of paroxysmal atrial fibrillation (AF). The diagnosis was made upon a 12‐lead ECG of the arrhythmia documented in the emergency room. The ECG showed an irregular tachycardia without wide QRS complexes.

Atrial fibrillation (AF) is a hetrogeneous disease that may present in many forms. Advances in our understanding of the mechanism responsible for AF have led to exciting new therapies that may soon provide a definitive cure.

β-microglobulin amyloid fibril-induced membrane disruption is enhanced by endosomal lipids and acidic pH [PDF]
Although the molecular mechanisms underlying the pathology of amyloidoses are not well understood, the interaction between amyloid proteins and cell membranes is thought to play a role in several amyloid diseases. Amyloid fibrils of β-microglobulin (βm),

Accumulation of TMEM106B fibrils composed of cleaved C-terminal fragments (CTF) of transmembrane protein 106B (TMEM106B) has recently been observed in the brains of elderly subjects and individuals with neurodegenerative diseases.

Cryo-EM structure and polymorphism of Aβ amyloid fibrils purified from Alzheimer’s brain tissue
The formation of Aβ amyloid fibrils is a neuropathological hallmark of Alzheimer’s disease and cerebral amyloid angiopathy. However, the structure of Aβ amyloid fibrils from brain tissue is poorly understood. Here we report the purification of Aβ amyloid

Atrial Fibrillation Degenerates Into Ventricular Fibrillation
![Figure][1] A 43-year-old man with paroxysmal atrial fibrillation (AF) and an implantable cardioverter defibrillator (ICD) placed for documented ventricular fibrillation (VF), presented with an ICD shock. Ventricular pre-excitation was not present.
