Researchers give knowledge on how lung microorganisms secure against attacking microbes Kumar Jeetendra | December 9, 2020 New insight on how bacteria in the lungs protect against invading pathogens has been published today in the open-access eLife journal. The study in mice shows that a strain of lung bacteria called Lactobacillus provides a barrier against Streptococcus pneumoniae (S. pneumoniae) colonisation in animals previously infected with influenza A virus when applied therapeutically following …
Colon lining discharges hydrogen peroxide to shield the body from gut microorganisms Kumar Jeetendra | December 10, 2020 Scientists at UC Davis Health have discovered that an enzyme in the colon lining releases hydrogen peroxide (H2O2) – a known disinfecting chemical – to protect the body from gut microbes. Their study, published Dec. 9 in the journal Cell Host and Microbe, sheds light on the way microorganisms are spatially organized in the colon. …
Researchers grow new serological assay for discovery of SARS-CoV-2 antibodies Kumar Jeetendra | December 13, 2020 Researchers at UC Santa Cruz have developed a novel serological assay for the detection of antibodies to SARS-CoV-2, the coronavirus which causes COVID-19. Rebecca DuBois, associate professor of biomolecular engineering at UC Santa Cruz, said the new method her staff developed is as accurate as the most dependable antibody tests now available, but is less …
Digital chest drainage systems could help reduce COVID-19 spread, research show Kumar Jeetendra | December 20, 2020 Pioneering research, which reveals digital chest drains generate and disperse less aerosol generated particles in comparison to traditional water seal systems, has been published in the Seminars in Thoracic and Cardiovascular Surgery journal. The research was led by a group of thoracic consultants from Guy’s and St Thomas’ NHS Foundation Trust — home to one …
Poisonous pesticide transformed into treatment against antibiotic-resistant bacteria Kumar Jeetendra | December 30, 2020 They are used as pesticides and fungicides. However, these substances could be poisonous to humans and cause mutations. As they aren’t frequently used, there’s little data about them in the medicinal chemistry literature. However, it has been suggested recently that the groups of substances that are traditionally avoided can help to fight pathogenic bacteria. Yet, …
Researchers arrive at significant achievement in leishmaniasis immunization advancement Kumar Jeetendra | January 11, 2021 Scientists have taken an important step forward in creating a controlled human infection model to test leishmaniasis vaccines. The University of York-led study identified and characterized a new strain of Leishmania parasite that will form the basis of a new controlled human infection model for the disease which is transmitted by the bite of sand …
An upgraded interaction to detach and cleanse magnetic nanoparticles Kumar Jeetendra | February 20, 2021 Magnetic nanoparticles biosynthesized by germs might soon play an significant role in biomedicine and biotechnology. Researchers at the University of Bayreuth have developed and optimized a procedure for the purification and isolation of the particles from bacterial cells. In initial tests, magnetosomes showed good biocompatibility when compared with human cell lines. The results presented in …
Novel platform has potential to detect many disease-related biomarkers in just one test Kumar Jeetendra | April 28, 2021 Most conventional molecular diagnostics usually detect only one disease-related biomarker. Fantastic examples are the PCR tests now used to diagnose COVID-19 by detecting a particular sequence from SARS-CoV-2. Such so-called singleplex methods give reliable results because they are”calibrated” to a single biomarker. However, determining whether a patient is infected with a new SARS-CoV-2 version or …
Mild cases of COVID-19 give enduring antibody, shows study Kumar Jeetendra | May 24, 2021 Months after recovering from mild cases of COVID-19, people still possess immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all of the while. The …
Why do certain lab-grown cultures exhibit poor growth? Kumar Jeetendra | July 1, 2021 Lab grown organisms such as bacteria sometimes exhibit poor growth due to various factors that deviate from their natural habitat. Some of the laboratory induced changes that must be taken into account are Growth & maintenance of cultures, Optimum growth temperatures, Methods of sterilization of media that are used to grow them & Glassware for …
Study uncovers the complex cell mechanism of Ebola Kumar Jeetendra | July 8, 2021 Mount Sinai researchers discovered the intricate cellular mechanisms of Ebola virus. This could help to explain the severe effects on people and provide potential treatment or prevention. The team published a study in mBio that showed how VP24, a protein from the Ebola virus interacts with the double-layered cell membrane (known as the nucleus) and …
Antimicrobial Resistance ‘Arms Race’ Realizes Advancements as the Post-Antibiotic Era Ensues Kumar Jeetendra | August 25, 2021 BOULDER, CO – August 25 2021 – Antimicrobial Resistance (AMR) is “one of the greatest threats to society, human and animal health, and economic prosperity.” Those are the unequivocal words regarding the gravity of antimicrobial-resistant bacteria from the National Institute of Antimicrobial Resistance Research and Education. When one considers the significance of AMR—including antibiotic resistance—a …
