Cellular aspects of in vitro fertilization (ultrastructural and cytogenetic studies of human gametes and zygotes)

Revisiones Sobre Biología Celular : RBC

Abstract

After the birth of Louise Brown in 1978 as a result of the successful development of in vitro fertilization (IVF) techniques by Edwards and Steptoe, the use of this procedure has become extremely widespread, both in technologically advanced societies and even in countries that do not meet the minimal sanitary standards. In good hands, IVF techniques provide results slightly lower than those allowed by nature, that is about 20% of pregnancies. In other cases, the procedure may become a nightware coupled to a swindle, and even endanger the life of the hopeful mother-to-be. Even in the better prepared centers, with the highest rates of success, IVF is still surrounded by a myriad of problems that must be solved to optimize its results and to reduce the risk of zygotic loss and of multiple pregnancies. On the other hand, IVF offers unimagined possibilities for research on fields of such interest as the reasons for the high incidence of nidation and/or developmental failures of human zygotes, the high percentage of infertile or sterile couples, pre-implantation diagnosis and gene therapy. These problems will only be solved if research in human cell aggregates (also called pre-embryos) is allowed. The potential medical, human and soc...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
