New focus on adverse impact of male factors in assisted reproductive treatments

The adverse impact of male factors in assisted reproductive treatments was brought into a clear and disturbing focus at the 10th Congress of the Asia Pacific Initiative on Reproduction (ASPIRE). The ASPIRE Congress, originally to be held in the Philippines, is being presented in virtual format – https://aspire2021.cme-congresses.com – to on-line participants in more than 100 countries because of ongoing […]

The Development of DNA Vaccines

The concept of a DNA vaccine was first proposed in 1990. Since then, DNA vaccines have been widely studied for their ability to induce both cellular and humoral immune responses against certain infectious agents. An overview of vaccinations Vaccines are considered to be one of the most significant medical advancements in recent human history. In short, a vaccination stimulates the […]

New genetic link to male infertility found

The findings published in eLife show that men with this unstable subtype of the Y chromosome have a significantly increased risk of genomic rearrangements. These rearrangements affect the sperm production process (spermatogenesis) and consequently, these men can be up to nine times more likely to have fertility issues. Molecular diagnostics of this genetic variant could help identify those at higher […]

Researchers test novel gene regulation approach to treat brain diseases

Researchers at the DZNE (Germany), at Massachusetts General Hospital (USA) and at the genomic medicine company Sangamo Therapeutics, Inc. tested a novel gene regulation approach to treat brain diseases such as Alzheimer's in laboratory studies. It leverages zinc finger proteins, which specifically bind to the DNA that codes for the protein Tau without altering it, thereby reducing Tau production in […]

Novel computer-guided design tool helps increase the efficiency of cell conversions

There is a great need to generate various types of cells for use in new therapies to replace tissues that are lost due to disease or injuries, or for studies outside the human body to improve our understanding of how organs and tissues function in health and disease. Many of these efforts start with human induced pluripotent stem cells (iPSCs) […]

Commonly used sweeteners may promote antibiotic resistance

Researchers in Australia have conducted a study showing that commonly used nonnutritive sweeteners can promote the spread of antibiotic-resistant genes in the intestine. The study found that the sweeteners saccharine, sucralose, aspartame, and acesulfame potassium all promoted horizontal transfer of the genes between bacteria in both environmental and clinical settings. The sweeteners accelerated the exchange of antibiotic resistance genes (ARGs) […]

SARS-CoV-2 DNA vaccine tested in animal model

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are being rolled out worldwide to control the COVID-19 (coronavirus disease 2019) pandemic. Multiple vaccines are necessitated to address the variant epidemics and also overcome the challenges that may be posed by the current vaccines (such as high cost, or low immunogenicity). In this context, a team of experts has […]

What is Krabbe disease?

Krabbe disease is also known by many other names, these include Globoid cell leukodystrophy, Galactosylcerebrosidase deficiency and Galactosylceramidase deficiency. (1, 4) It is a very rare condition that is caused by a genetic defect that affects the nervous system. (2) Types of Krabbe disease There are two main types of Krabbe disease: early-onset (infantile) Krabbe disease late-onset (juvenile- or adult-onset) […]
