Received: 01 August 2018;  Published: 25 November 2018;  doi: 10.21926/obm.geriatr.1804020

Abstract

Improved understanding of the underlying cellular dysfunction and resultant neuropathology of sporadic Alzheimer’s disease (AD) is needed to stem the anticipated public health crisis due to this increasingly common neurodegenerative disease. The four main risk factors for sporadic AD are age, female gender, genetic carriage of the APOE4 allele and type two diabetes mellitus (T2DM). Each of these four risk factors is associated with impaired and/or dysfunctional autophagy suggesting that perturbation of autophagy is [...]

Abstract

All of us are intuitively aware, and many of us explicitly aware as well, of the meaning of geriatrics as a specialty. After all, most of us practice geriatrics or we have been intimately involved with this area and we are know the reality of geriatrics. Or do we? Geriatrics is an oddly ill-defined specialty when you look at it more carefully. Some of us practice medicine, some of us practice in the social sciences, and many of us simply do our jobs day-to-day and try to get by. What we share, however, is the heart [...]

The Feasibility and Necessity of a Revolution in Geriatric Medicine

Received: 19 February 2017;  Published: 13 April 2017;  doi: 10.21926/obm.geriatr.1702002

Abstract

Currently, geriatric medicine consists mainly of palliative treatment of the disorders that characterize senile decay. This is perfectly compatible with the prevailing view that aging is the inevitable result of multiple degenerative processes that cannot be treated effectively as they are, in themselves, inevitable and irreversible. This interpretation of aging clashes with a mass of data and arguments that, conversely, indicate that aging is a specific physiological function, favoured by supra-individual natural [...]

A New Database on Constitutional Human Ring Chromosomes

Received: 20 April 2025;  Published: 26 June 2025;  doi: 10.21926/obm.genet.2502298

Abstract

Human ring chromosomes (RCs) constitute one of the rarest described inborn chromosomal rearrangements. At first, they seem to be just another subgroup of structural chromosomal aberrations like translocations, inversions, or insertions. However, RCs are more complex, as they almost always occur in conjunction with a mosaic karyotype constitution, resulting in mosaic monosomy of the affected chromosome. Most likely due to the latter effect, a genotype-phenotype correlation is still not available. To proceed with sol [...]

Abstract

Generally, in reciprocal translocations there are no gains or losses of genetic material. From the clinical point of view, its primary importance lies in the fact that it can generate errors due to incorrect chromosome segregation during meiosis in carriers. On the other hand, other mutations are less frequent in the genome, specifically in the DNA breakpoints implied in these translocations. In Latin America there are no large-scale reports about this topic. To contribute to the study of reciprocal translocations [...]
