Medical News Today: Alzheimer's: Synthetic protein blocks toxic beta-amyloid

Scientists have designed a protein that folds into alpha sheets that can block toxic beta-amyloid in brain cells before it forms into large clumps.

This study was carried out in accordance with the recommendations of the National Animal Care and Use Committee of the University of Buenos Aires (CICUAL). The protocol was approved by the CICUAL. Mice were kept under a 12-h light/dark cycle, with controlled temperature (23 ± 2°C) and humidity (40–60%) and had ad libitum access to food and water. To produce hTDP-43 transgenic lines, as described previously (Igaz et al., 2011), pronucleus of fertilized eggs from C57BL/6J × C3HeJ F1 matings were injected with a vector containing hTDP-43-WT cDNA. Monogenic tetO-TDP-WT12 mice wer...

Conclusions: This study improves the knowledge on clinical significance of RBD symptoms in ET patients. Our preliminary findings demonstrate that presence of RBD in ET is associated with neurocognitive impairment, but not with cardiac autonomic dysfunction. Further longitudinal studies are needed to investigate whether ET patients with RBD will develop a frank dementia over the time. Introduction Essential tremor (ET) is one of the most common neurological disease among adults. Traditionally, it is defined by a core of clinical motor symptoms characterized by kinetic/postural tremor affecting hand, head, or other par...

Conclusions: Lifestyle factors, such as physical activity, sleep, and social activity appear to be associated with cognitive function among older people. Physical activity and appropriate durations of sleep and conversation are important for cognitive function. Introduction Dementia is a major public health issue worldwide, with a serious burden for patients, caregivers, and society, as well as substantial economic impacts (1). Although the prevalence of late-life cognitive impairment and dementia are expected to increase in future, effective disease-modifying treatments are currently unavailable. Therefore, unders...

This study was hypothesis-driven; the genetic variants were selected for being previously and substantially genotyped. The big sample size and the rich panel of other biomarkers allowed the authors to conduct much more detailed analyses on this topic. The third article by Provenzi et al. proposed their perspectives on the role of telomeres in premature birth and discussed the potential implications for early adversity and care in the neonatal intensive care unit (Pavanello et al.). Indeed, the speculation of telomeres in aging begins in the premature aging syndrome. It is thus interesting to examine if telomeres also play...

Authors: Śmigórska A, Śmigórski K, Rymaszewska J Abstract The following article discusses the possibility of applying a rehabilitation strategy known as Errorless Learning (EL) in patients suffering from Alzheimer's disease (AD). The authors present the issue in the context of the knowledge on the effectiveness of administering neuropsychological interventions in patients with AD. The history of the EL method development is presented as well as techniques used in its domain. The novelty of the EL methodological approach is shown. It is emphasized that EL, in contrast with the majority of neuropsycho...

Ketogenic medium chain triglycerides (kMCTs) could improve cognition in MCI by providing the...

While clearing out amyloid-β from the brain has so far proven to be a matter of too little, too late in late stage Alzheimer's disease patients, there is still a strong basis of evidence for the merits of removing amyloid-β. It is reasonable to say that it causes meaningful pathology; if people did not accumulate amyloid-β deposits, then there would be no consequent disarray in the function of neurons and immune cells in the brain. This particular foundation of the development of dementia would be removed. Even if the mechanisms of the later stages of Alzheimer's, the chronic inflammation and tau protein agg...

In conclusion, insular sub-regional atrophy, particularly the anterior dorsal region, may contribute to cognitive and neuropsychiatric deficits in neurodegeneration. Our results support anterior insular cortex vulnerability and convey the differential involvement of th e insular sub-regions in functional deficits in neurodegenerative diseases.

AbstractDespite significant advancements in the field of molecular neurobiology especially neuroinflammation and neurodegeneration, the highly complex molecular mechanisms underlying neurodegenerative diseases remain elusive. As a result, the development of the next generation neurotherapeutics has experienced a considerable lag phase. Recent advancements in the field of genome editing offer a new template for dissecting the precise molecular pathways underlying the complex neurodegenerative disorders. We believe that the innovative genome and transcriptome editing strategies offer an excellent opportunity to decipher nove...
