Study looks at genetic background of healthy people who develop severe Covid-19 illness

June 13, 2020 – To help disentangle the secrets of Covid-19 disease, researchers are sequencing the DNA of young grown-ups and children who suffer from extreme Covid-19 disease ailments in spite of having no hidden clinical issues. The scientists are searching for hereditary genetic risk factors that could put certain people at high danger of getting seriously sick from the novel coronavirus,

Diagnoses for children with rare genetic diseases by 3-D facial scans

June 07, 2020 – Most children with rare genetic diseases spend years undergoing medical tests and waiting for a diagnosis—a long, exhausting process that takes its toll on children and their families. Almost half of these children never get a definitive diagnosis.

In a new and exciting development,

Host factors may influence Covid-19 severity more than viral genetic variation

May 22, 2020 – Host factors (i.e., disease phenotypes and/or predispositions) instead of viral genetic variation seem to impact more on sickness severity among Covid-19 patients, as indicated by an investigation from China. Scientists in Shanghai analyzed clinical, atomic, and immunological information from in excess of 300 individuals with affirmed Covid-19.

Abdominal aortic aneurysm: Genetic scoring can identify more men at risk

May 07, 2020 – Abdominal aortic aneurysm (AAA) is a localized enlargement of the abdominal aorta such that the diameter is greater than 3 cm or more than 50% larger than normal. AAAs usually cause no symptoms, except during rupture.

Besides the now approved remdesivir: Emerging options to treat Covid-19

May 03, 2020 –  The world is desperate in the search for a treatment or better yet a vaccine in the Covid-19 pandemic. Slowly, there are some options emerging at least for the treatment of seriously ill Covid-19 patients. First of all,  the American Food and Drug Administration just issued an emergency use authorization (EUA) for the investigational antiviral drug remdesivir for the treatment of suspected or laboratory-confirmed COVID-19 in adults and children hospitalized with severe disease.

Could DNA testing help the most seriously affected Covid-19 patients?

April 28, 2020 – Coronavirus disease 2019 (Covid-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province,

Klotho’s role in some patients with Alzheimer’s disease revealed?

April 24, 2020 – The klotho gene is named after the fanciful Greek goddess of destiny Clotho who turns the string of life known to be related with longer life and improved cognizance. In modern biology, allelic variants of the klotho gene in fact have been associated with long life span.

Inherited mutation in ELP1 predisposes children to medulloblastoma

April 03, 2020 – Medulloblastoma is the most common malignant pediatric brain tumor. Medulloblastomas are invasive, rapidly growing tumors that, unlike most brain tumors, spread through the cerebrospinal fluid and frequently metastasize to different locations along the surface of the brain and spinal cord.

Three idiopathic pulmonary fibrosis (IPF)-associated genes newly identified

March 05, 2020 – Idiopathic pulmonary fibrosis (IPF) is a type of chronic scarring lung disease characterized by a progressive and irreversible decline in lung function. Symptoms typically include gradual onset of shortness of breath and a dry cough.

HSD3B1 Genotype Predicts Prostate Cancer Outcomes

February 28, 2020 – A very recent report elucidates the possible prospective power of the knowledge about the genetic background of patients when concerned with certain clinical endpoints (disease states) and associated genes.

The researchers in the present study analyzed outcomes in white men enrolled in the E3805 CHAARTED clinical trial according to HSD3B1 genotype,

  • The protein that stands between us and autoimmunity July 2, 2020
    The immune system is supposed to protect from external microbial invaders, but sometimes it turns its efforts inward, potentially resulting in autoimmune diseases. In a new study, researchers from Osaka University have discovered how reversible modifications to DNA by certain proteins protect from autoimmune diseases, and conversely, how the absence of these proteins paves the […]
  • Concern following gene therapy adverse events July 2, 2020
    The Editor-in-Chief of Human Gene Therapy, the first journal devoted to the field of gene therapy, and one of the world's leading experts on gene therapy have co-authored a new editorial, Moving Forward After Two Deaths in a Gene Therapy Trial of Myotubular Myopathy, in response to the news of two deaths in a now-halted […]
  • How a mutation on the novel coronavirus has come to dominate the globe July 2, 2020
    Flashback to mid-March: the novel coronavirus had reached San Diego, California. Few people could get tested, and even less was known about how the virus mutated as it spread from person to person.
  • High-definition likelihood inference of genetic correlations across human complex traits July 2, 2020
    Evaluating the genetic correlations across our phenotypes is of essential importance for understanding disease etiology and other potential causality. A new method—published in the journal Nature Genetics—vastly improves estimates of genetic correlations using established resources from genome-wide association studies.
  • Research team develops technology to improve effectiveness of stem cells in regenerative medicine July 2, 2020
    Stem cells have been holding great promise for regenerative medicine for years. In the last decade, several studies have shown that this type of cell, which in Spanish is called "mother cell" because of its ability to give rise to a variety of different cell types, can be applied in regenerative medicine for diseases such […]
  • Towards lasers powerful enough to investigate a new kind of physics July 3, 2020
    In a paper that made the cover of the journal Applied Physics Letters, an international team of researchers has demonstrated an innovative technique for increasing the intensity of lasers. This approach, based on the compression of light pulses, would make it possible to reach a threshold intensity for a new type of physics that has […]
  • Does DNA in the water tell us how many fish are there? July 3, 2020
    Researchers have developed a new non-invasive method to count individual fish by measuring the concentration of environmental DNA in the water, which could be applied for quantitative monitoring of aquatic ecosystems.
  • Fluorine enables separation-free 'chiral chromatographic analysis' July 2, 2020
    Researchers from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences recently developed a new platform for rapid chiral analysis, producing chromatogram-like output without the need for separation.
  • Hot flushes and night sweats linked to 70% increase in cardiovascular disease July 2, 2020
    New research from The University of Queensland has found that women who have hot flushes and night sweats after menopause are 70 per cent more likely to have heart attacks, angina and strokes.
  • The protein that stands between us and autoimmunity July 2, 2020
    Researchers from Osaka University identified the epigenetic proteins Tet2 and Tet3 as key regulators of B cell function. They showed that these proteins suppress B cell function and conversely, that Tet2/Tet3 knockout mice develop a mild form of systemic lupus erythematosus due to hyperactivation of T cells. These findings could help develop a novel treatment […]
