Mad cow disease adaptation key found

EDMONTON, Alberta, March 17 (UPI) -- Canadian researchers discovered a minuscule change in prions' makeup appears to give mad cow disease the ability to adapt and spread to other animals.

AbstractHuman prion diseases (HPDs) are progressive and fatal neurodegenerative diseases caused by abnormal prion protein (PrPSc). They can be sporadic, genetic, or acquired. Sporadic HPDs include sporadic Creutzfeldt –Jakob disease (CJD) and sporadic fatal insomnia. Genetic HPDs include genetic CJD, Gerstman–Sträussler–Scheinker disease and fatal familial insomnia. Acquired HPDs include Kuru, variant CJD, and iatrogenic CJD. The World Health Organization clinical diagnostic criteria for HPDs include clini cal findings, cerebrospinal fluid (CSF) protein markers, and electroencephalography, and the UK...

Research advances in recent years have shown that some individuals with vegetative state or minimally conscious state can emerge to higher states of consciousness even years after injury. A minority of behaviorally unresponsive patients with vegetative state have also been shown to follow commands, or even communicate, using neuroimaging or electrophysiological techniques. These advances raise ethical questions that have important implications for clinical care. In this article, the authors argue that adopting a neuropalliative care approach can help clinicians provide ethical, compassionate care to these patients and their caregivers.

Conclusions The incidence of CJD, in SWSLHD, exceeds the national average of 1/million. Cost-effective, adequate diagnostic and screening tools, implementab le over a large population, will become increasingly essential.

Tauopathies like Alzheimer's disease are characterized by the spread of tau aggregates through the brain. Tau is one of the few molecules in the body that can become altered in a way that encourages other copies of the same molecule to also alter, causing aggregates to form. These aggregates and their surrounding biochemistry are disruptive to cell function and toxic to cells. A number of neurodegnerative conditions are associated with protein aggregates of amyloid-β, α-synuclein, and tau. The mechanisms by which this spread occurs are debated, but researchers strongly suspect a role for glial cells in this proc...

AbstractHuman prion diseases are fatal neurodegenerative disorders that include sporadic, infectious and genetic forms. Inherited Creutzfeldt-Jakob disease due to the E200K mutation of the prion protein-coding gene is the most common form of genetic prion disease. The phenotype resembles that of sporadic Creutzfeldt-Jakob disease at both the clinical and pathological levels, with a median disease duration of 4 months. To date, there is no available treatment for delaying the occurrence or slowing the progression of human prion diseases. Existingin vivo models do not allow high-throughput approaches that may facilitate the ...

This report describes the patient’s insidious clinical evolution and the paraclinical examinations and pathology reports gathered at different time points of disease progression. Unfortunately, the absence of typical clinical and paraclinical features of classic sporadic Creutzfeldt–Jakob disease made the brain biopsy surgery necessary. This case report illustrates the diagnostic difficulties posed by the phenotypic heterogeneity of sporadic Creutzfeldt–Jakob disease and urges clinicians to consider this diagnosis even in patients who do not fulfil the typical clinical disease criteria. Furthermore, it hi...

We report the case of a 56-year-old woman with the rapidly progressive cognitive impairment, motor dysfunctions and the fulminant neurological deterioration to akinetic mutism during the five weeks' hospitalisation. The probable diagnosis of sCJD was based on medical history and characteristic findings in MRI. The positive result of the real-time quaking-induced conversion (RT-QuIC) test and presence of protein 14-3-3 were obtained post-mortem and definite diagnosis was confirmed by neuropathological examination. In this paper we would like to emphasize the difficulties in reaching the diagnosis and the need for a series o...
