DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

A new framework to support the implementation of 'health promoting schools'

The first global standards to embed health and wellbeing into the education system have been created amid a rise in mental health problems during the COVID-19 pandemic.

Yeast cell machinery seamlessly 'reads' the unnatural ingredients in the genetic recipe

If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs -- A, T, C, G -- make us who and what we are.

Maternal and paternal inflammatory disease can affect pregnancy outcomes

Data presented at the 2021 EULAR congress show women with rheumatoid arthritis (RA) are at increased risks of adverse pregnancy outcomes, especially pre-term birth and babies small for gestational age.

Scientists develop low-cost lab-on-paper device for rapid and accurate detection of SARS-CoV-2

A team of scientists from the University of Connecticut, USA, has developed a low-cost lab-on-paper technology to rapidly and easily detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The work has recently been published in a Royal Society of Chemistry’s Lab on a Chip journal.

Study shows how epigenetic factors modulate the risk of type 1 diabetes

Genetics plays a major role in determining a person’s risk of developing type 1 diabetes, but environmental and lifestyle factors are also important. In an article recently published in Chinese Medical Journal, a team of researchers explore the interplay of genetic and environmental factors by summarizing the literature on type 1 diabetes and epigenetics—the study of how gene expression patterns can be modified.

Which vitamins and minerals help with COVID?

A study published in the journal Inflammopharmacology reviewed recent data related to the role of vitamins and minerals in treating COVID-19 patients. The primary goal of the review is to highlight the possible therapeutic role of vitamins A, B, C, D, E and K, and micronutrients as immunity boosters in COVID-19 patients.

$Researchers report a new genetic cause for infantile fractures$

Researchers report a new genetic cause for infantile fractures

An intrauterine fracture is a rare finding during routine prenatal imaging. This condition can be due to maternal trauma, genetic disorders of the skeleton, as well as other predisposing maternal metabolic and vascular disorders.

Medieval plague victims were buried with considerable care and attention, shows study

In the mid-14th century Europe was devastated by a major pandemic - the Black Death - which killed between 40 and 60 per cent of the population. Later waves of plague then continued to strike regularly over several centuries.

Presence of certain stem cells linked to nongenetic resistance mechanisms of cancer cells

Cancer cells can develop resistance to therapy through both genetic and non-genetic mechanisms. But it is unclear how and why one of these routes to resistance prevails.

Study: Cancer cells grown in culture dishes have less parity with their human sources

In a bid to find or refine laboratory research models for cancer that better compare with what happens in living people, Johns Hopkins Medicine scientists report they have developed a new computer-based technique showing that human cancer cells grown in culture dishes are the least genetically similar to their human sources.

Foresight Diagnostics to demonstrate utility of PhasED-Seq technology at ICML meeting

Foresight Diagnostics, the emerging leader in blood-based lymphoma disease monitoring, announced today that clinical performance of its minimal residual disease (MRD) detection platform in diffuse large B-cell lymphoma (DLBCL) will be presented at the 16th International Conference on Malignant Lymphoma (ICML) on June 18-22, 2021.

Study validates accuracy of new molecular test for tuberculosis diagnosis

The 'Xpert Ultra' molecular test has a greater capacity than its predecessor ('Xpert MTB/RIF') in detecting tuberculosis cases, either passively (i.e. people who attend the hospital with disease symptoms) or actively (searching for possible cases in the community among contacts of cases).
