On the nature of coincidental events [PDF]

, 2022
It is a common opinion that chance events cannot be understood in causal terms. Conversely, according to a causal view of chance, intersections between independent causal chains originate accidental events, called “coincidences.” The present paper takes ...

MRI Features of Stroke-Like Episodes in Mitochondrial Encephalomyopathy With Lactic Acidosis and Stroke-Like Episodes

Frontiers in Neurology, 2022
Mitochondrial myopathy encephalopathy lactic acidosis and stroke-like episodes (MELAS) is an important cause of stroke-mimicking diseases that predominantly affect patients before 40 years of age. MELAS results from gene mutations in either mitochondrial

Patent foramen ovale leading to mismanagement in a mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke‐like episodes patient

Clinical Case Reports, 2023
Key Clinical Message The stroke‐like episodes and brain MRI lesions in MELAS usually have a nonischemic pattern, are resolved over time, and have a migrating pattern that helps us distinguish them from ischemic cerebral infarcts. Nevertheless, conditions

The MeLa BitChute Dataset

Proceedings of the International AAAI Conference on Web and Social Media, 2022
In this paper we present a near-complete dataset of over 3M videos from 61K channels over 2.5 years (June 2019 to December 2021) from the social video hosting platform BitChute, a commonly used alternative to YouTube. Additionally, we include a variety of video-level metadata, including comments, channel descriptions, and views for each video. The MeLa-

MELAS: A Multigenerational Impact of the MTTL1 A3243G MELAS Mutation [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2014
Background:the maternally inherited MTTL1 A3243G mutation in the mitochondrial genome causes MelaS (Mitochondrial encephalopathy lactic acidosis with Stroke-like episodes), a condition that is multisystemic but affects primarily the nervous system. Significant intra-familial variation in phenotype and severity of disease is well recognized.Methods ...
