OCTOBER 26TH, 2023 CONN HASTINGS DIAGNOSTICS, GENETICS Researchers at the University of Massachusetts Amherst have developed a new method of detecting very small amounts of DNA. The breakthrough could allow clinicians to spot genetic markers of disease at the point-of-care, as the approach does not require conventional laboratory analysis, which is usually time-consuming and costly. In fact, the...

Effective treatment for rare sight-threatening infection: Clinical trial
by University College London Credit: samer daboul from PexelsA new drug candidate, based on pioneering UCL and Moorfields Eye Hospital research and currently under development by SIFI S.p.A., has been found to be highly effective in treating a rare sight-threatening eye infection in a new international clinical trial. The findings, published in Ophthalmology, describe the efficacy...
Find-and-replace genome editing with CRISPR: A promising therapeutic strategy
by Bar-Ilan University Credit: Pixabay/CC0 Public DomainSevere combined immunodeficiencies (SCIDs) are a group of debilitating primary immunodeficiency disorders, primarily caused by genetic mutations that disrupt T-cell development. SCID can also affect B-cell and natural killer cell function and counts. Left untreated, SCID proves fatal within the first year of life. The conventional treatment for SCID patients...
Study identifies genetic cause for some brain tumors

Credit: Hinda NajemScientists have uncovered a genetic explanation for one subset of common brain tumors, according to...
First rapid tests for chlamydia, gonorrhea exhibit 100% sensitivity
by Ashley WennersHerron, Pennsylvania State University Schematic representation of two approaches based on changes in absorbance and lateral flow methods, utilizing novel oligonucleotide probes targeted toward Chlamydia trachomatis and Neisseria gonorrhoeae, for the clinical determination of chlamydia and gonorrhea. The addition of genetic material (bacterial DNA from either Chlamydia trachomatis or Neisseria gonorrhoeae) will result in...
Risk of viral airborne transmission peaks within five seconds of face-to-face encounters, study finds
by University of Tsukuba Researchers moved a mannequin equipped with a device that emits aerosol particles to examine the number and movement of the particles. Credit: Takeshi Asai, professor emeritus at the University of TsukubaThe main transmission routes identified initially for the novel coronavirus infection were droplet and contact transmission. Airborne transmission by aerosol particles was...
Is red meat intake linked to inflammation?
Peer-Reviewed Publication BAYLOR COLLEGE OF MEDICINE Inflammation is a risk factor for many chronic diseases, including cardiovascular disease (CVD), and the impact of diet on inflammation is an area of growing scientific interest. In particular, recommendations to limit red meat consumption are often based, in part, on old studies suggesting that red meat negatively affects...
CBD and CBG may promote bone fracture healing, manage pain
by Zachary Sweger, Pennsylvania State University Penn State College of Medicine researchers are studying how cannabinoids may manage pain and promote bone healing in bone fractures. Fluorescence microscopy reveals how periosteal bone progenitors, which later develop into specialized bone cells that help bone tissue for, appear in healing tissue.

The blind use of AI in health care can lead to invisible discrimination
by University of Copenhagen Credit: CC0 Public DomainArtificial intelligence can help health care systems under pressure allocate limited resources, but also lead to more unequal access. This is demonstrated by a research collaboration between the University of Copenhagen, Rigshospitalet and DTU that investigated whether AI can spot the risk of depression equally across different population segments....
