Biosensors on the road to early diagnostic and surveillance of Alzheimer's disease.

Biosensors on the road to early diagnostic and surveillance of Alzheimer's disease. Talanta. 2020 May 01;211:120700 Authors: Carneiro P, Morais S, do Carmo Pereira M Abstract Alzheimer's disease is a debilitating and largely untreatable condition with subtle onset and slow progression over an extensive period of time, which culminate in increasing levels of disability. As Alzheimer's disease prevalence is expected to grow exponentially in the upcoming decades, there is an urgency to develop analytical technologies for the sensitive, reliable and cost-effective detection of Alzheimer's disease biomarkers. Biosensors are powerful analytical devices that translate events of biological recognition on physical or chemical transducers into electrical, thermal or optical signals. The high sensitivity and selectivity of biosensors associated with easy, rapid and low-cost determination of analytes have made this discipline one of the most intensively studied in the past decades. This review centers on recent advances, challenges and trends of Alzheimer's disease biosensing particularly in the effort to combine the unique properties of nanomaterials with biorecognition elements. In the last decade, impressive progresses have been made towards the development of biosensors, mainly electrochemical and optical, for detection of Alzheimer's disease biomarkers in the pico- and femto-molar range. Nonetheless, advances in multiplexed detection, robustness, stability and ...

Basel, 11 September 2020 – Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced new data that show OCREVUS® (ocrelizumab) is a highly effective treatment option for people with relapsing-remitting multiple sclerosis (RRMS) who experienced a suboptimal response to their prior disease modifying therapy (DMT). Subgroup analys is from the two-year open-label Phase IIIb CASTING study also demonstrates that patients benefit across a wide range of disease related and demographic subgroups, regardless of prior treatment background. Findings will be presented at MSVirtual2020, the 8th Joint Meeting of the Americas Committee...

Basel, 10 September 2020 - Roche (SIX: RO, ROG; OTCQX: RHHBY) will present new ENSPRYNG ® (satralizumab) data on reducing relapse severity in the treatment of neuromyelitis optica spectrum disorder (NMOSD), a rare disease of the central nervous system. These data are being presented at MSVirtual2020, the 8th joint ACTRIMS-ECTRIMS meeting, in addition to longer-term efficacy data supporting the continued effect of ENSPRYNG on reducing the risk of NMOSD relapse, as well as its favourable benefit:risk profile.“The data for ENSPRYNG at MSVirtual2020 are promising and suggest it significantly reduces relapse severity ...

BackgroundIn March 2020, the World Health Organization declared a global pandemic due to the novel coronavirus SARS-CoV-2 and several governments planned a national quarantine in order to control the virus spread. Acute psychological effects of quarantine in frail elderly subjects with special needs, such as patients with dementia, have been poorly investigated. The aim of this study was to assess modifications of neuropsychiatric symptoms during quarantine in patients with dementia and their caregivers.MethodsThis is a sub-study of a multicenter nation-wide survey. A structured telephone interview was delivered to family ...

We report that electrical stimulation (ES) stimulation of post-stroke aged rats led to an improved functional recovery of spatial long-term memory (T-maze), but not on the rotating pole or the inclined plane, both tests requiring complex sensorimotor skills. Surprisingly, ES had a detrimental effect on the asymmetric sensorimotor deficit. Histologically, there was a robust increase in the number of doublecortin-positive cells in the dentate gyrus and SVZ of the infarcted hemisphere and the presence of a considerable number of neurons expressing tubulin beta III in the infarcted area. Among the genes that were unique...

This study aimed to characterize the role of BDNF in age-related microglial activation. Initially, we found that degrees of microglial activation were especially evident in the substantia nigra (SN) across different brain regions of aged mice. The levels of BDNF and TrkB in microglia decreased with age and negatively correlated with their activation statuses in mice during aging. Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while shTrkB...

CONCLUSIONS: The findings suggest that novel learning still is possible for people living with dementia, even without the implementation of focussed interventions. This study further emphasizes the procedural nature of learning for people living with dementia as the woman's embodied actions were carried out in an increasingly more direct fashion. Implications for rehabilitation For people living with dementia, learning in everyday activities is facilitated by repeated exposure to the activity and the scaffolding practices of a more experienced communicative partner. In instances of novel learning, one should not underestim...
