Exogenous 3-iodothyronamine rescues the entorhinal cortex from β-amyloid toxicity.

CONCLUSIONS: Our results suggest that T1AM and TAAR1 are part of an endogenous system that can be modulated to prevent synaptic and behavioral deficits associated with Aβ-related toxicity. PMID: 31709926 [PubMed - as supplied by publisher]

CONCLUSION: The low agreement between amyloid PET/CT and previous clinical and instrumental assessments that we found in our study suggests that the amyloid PET/CT provides additional and early information. To perform an early and differential diagnosis of AD could have a great impact on the patient's management and cost of care in order to perform the correct therapeutic interventions and to allow family members to manage adequately the patient's demanding care.

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications. To What Degree Does Loss of Skeletal Muscle with Age Contribute to Immunosenescence? https://www.fightaging.org/archives/2019/11/to-what-degree-does-loss-of-skeletal-muscle-with-age-contribute-to-immunosenescence/ Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

The mTOR inhibitor rapamycin is well known to slow aging in animal models. As for most of the methods shown to achieve this goal in short-lived species, upregulation of cellular maintenance processes such as autophagy features prominently in the changes produced by the drug. Every one of these approaches that produce sweeping changes in cellular metabolism and a general slowing of age-related decline provides the research community with an essentially unlimited range of projects to undertake when it comes to assessing specific metrics of aging and how they are affected. Here, researchers look at how rapamycin affect...

AbstractNeuroimaging can provide important biomarkers and is very useful for supporting dementia diagnosis. This review summarizes the neuroimaging findings of dementia with Lewy bodies (DLB), frontotemporal lobar degeneration (FTLD), and normal pressure hydrocephalus (NPH). In DLB, medial temporal atrophy is milder than that of Alzheimer ’s disease. 2-fluoro-2-deoxy-d-glucose-positron emission tomography and brain perfusion single-photon emission computed tomography demonstrate hypometabolism and hypoperfusion in the occipital lobe, in addition to decreased metabolism and perfusion in the parietotemporal, posterior ...

The objective of this narrative review is to examine the contribution of this hypothesis in the care of African older adults with neurodegenerative conditions (i.e., dementia (Alzheimer's disease)) or with mild cognitive impairments. Although studies in developed countries have examined people of African descent (i.e., with African Americans), only the limited findings presented in this review reflect how these conditions are also important for the African continent. This review revealed that no studies have examined the effects of cardiorespiratory fitness on neurodegenerative disease in Africa. African nations, like many...

This study was aimed to estimate variations of measures of cardiovascular risk in Alzheimer's dementia by pharmacogenetic analyses of the effects of angiotensin-converting enzyme (ACE) inhibitors and statins. Methods: Consecutive patients were prospectively followed to study variations of creatinine clearance and blood pressure for one year, estimated by correlating the effects of ACE inhibitors with the ACE Alu I/D polymorphism and genotypes or haplotypes of rs1800764 or rs4291, and the effects of statins with LDLR (low-density lipoprotein receptor) genotypes or haplotypes of rs11669576 (exon 8) or rs5930 (exon 10), ...

CONCLUSIONS: Automated analysis of HMPAO-SPECT data of MCI and SCC+ patients showed significant perfusion differences in medial temporal region and impaired verbal memory, both of which are known features of Alzheimer's dementia. Perfusion patterns and verbal memory performance in SCC+ are more similar to MCI than SCC-. Thus, SPECT analysis could distinguish those subjects whose perfusion pattern resembles that of an MCI from those who don't. In our opinion, this could identify two populations with a different risk of progression to AD, with SCC+ subjects needing further diagnostic examination and repeated follow-up. ...

Authors: Wanleenuwat P, Iwanowski P, Kozubski W Abstract Alzheimer's disease (AD) is the most common form of dementia manifesting as alterations in cognitive abilities, behavior and deterioration in memory which is progressive, leading to gradual worsening of symptoms. Major pathological features of AD are accumulations of neuronal amyloid plaques and neurofibrillary tangles, with early lesions appearing primarily in the hippocampus, the area of the brain involved in memory and learning. Cardiovascular related risk factors are believed to play a crucial role in disease development and the acceleration of cognitive ...
