Deforestation in the Amazon builds variety of antibiotic-resistant bacteria Kumar Jeetendra | March 12, 2021 In Brazil, a study conducted by researchers affiliated with the University of São Paulo (USP) and collaborators showed that deforestation in the Amazon causes an increase in the diversity of antibiotic-resistant bacteria. An article on the study, published in Soil Biology and Biochemistry, compares the microorganisms that live in the land of indigenous forest with …
Study shows how self-swimming microorganisms get by in harsher conditions Kumar Jeetendra | March 18, 2021 Many bacteria swim towards nutrients by rotating the helix-shaped flagella attached to their bodies. As they proceed, the cells may either’run’ in a straight line, or’fall’ by varying the rotational directions of the flagella, inducing their avenues to intentionally alter course. Through a process named’chemotaxis,’ bacteria can decrease their rate of tumbling at higher levels …
Bacteria residing within inside tumor cells can support malignant growth immunotherapy Kumar Jeetendra | March 22, 2021 Cancer immunotherapy may get a boost from an unexpected direction: bacteria residing within tumor cells. The study may also help clarify the connection between immunotherapy and the intestine microbiome, describing the findings of earlier research that the microbiome impacts the success of immunotherapy. Immunotherapy remedies of the last decade or so have dramatically improved healing …
Universal microplastics can become ‘centers’ for antibiotic-resistant bacteria Kumar Jeetendra | March 22, 2021 It is estimated that an average-sized wastewater treatment plant serving approximately 400,000 inhabitants will discharge up to 2,000,000 microplastic particles to the environment every day. Yet, researchers are still learning the ecological and human health impact of these ultra-fine plastic particles, less than 5 millimeters in length, found in everything from makeup, toothpaste and clothes …
Study uncovers molecular mechanisms of drug resistance in Mycobacterium tuberculosis Kumar Jeetendra | April 9, 2021 A consortium of researchers from Russia, Belarus, Japan, Germany and France led by a Skoltech scientist have uncovered the way by which Mycobacterium tuberculosis survives in iron-deficient states by using rubredoxin B, a protein by a rubredoxin family that play an essential role in adaptation to changing environmental conditions. The new study is part of …
Imbalanced bacterial community in the gums connected to Alzheimer’s infection biomarker Kumar Jeetendra | April 12, 2021 Older adults with more harmful than healthy bacteria in their gums are more likely to have evidence for amyloid beta–a key biomarker for Alzheimer’s disease–in their cerebrospinal fluid (CSF), according to new research from NYU College of Dentistry and Weill Cornell Medicine. However, this imbalance in oral bacteria was not associated with another Alzheimer’s biomarker …
Researchers examine how oxygen radicals secure against cancer Kumar Jeetendra | April 26, 2021 Initially, oxygen radicals – reactive oxygen species, or ROS for short – were thought of as exclusively harmful in the body. They’re produced, by way of example, by smoking or UV radiation. Because of their high reactivity, they could damage many important molecules in cells, including the hereditary molecule DNA. As a result, there’s a …
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 …
A solitary archaeal compound can create a spectacular scope of regular and non-common cardiolipins Kumar Jeetendra | May 7, 2021 Cells of all life forms are surrounded by a membrane that’s made of phospholipids. One of them are the cardiolipins, which form another class due to their distinctive structure. When studying the enzyme that’s responsible for generating cardiolipins in archaea (single-cell organisms that constitute a separate domain of life), biochemists at the University of Groningen …
Unevenness in gut microbiota could assume a vital part in movement of inflammatory skin disorder Kumar Jeetendra | May 7, 2021 Findings presented at the EADV 2021 Spring Symposium imply that an imbalance in gut microbiota (dysbiosis), could play a substantial role in the progression of inflammatory skin disease, Hidradenitis Suppurativa (HS). HS is a painful, long-term skin condition, with a chronic and relapsing nature that significantly impacts patients’ quality of life. Researchers at Hacettepe University …
Study proposes expected role for probiotics in forestalling respiratory infections Kumar Jeetendra | May 15, 2021 Daily probiotic use was associated with fewer upper respiratory symptoms in overweight and older people, according to a study which suggests a potential role for probiotics in preventing respiratory infections. Researchers re-analyzed detailed daily diaries of 220 patients who engaged in a previous double-blind placebo-controlled study on probiotics and weight loss. Reviewing the entries for …
Genomic study tracks the rise of multidrug resistant E.coli Kumar Jeetendra | May 17, 2021 Antibiotic resistance in E.coli has been steadily rising since the early 2000s despite attempts to control it, a new study suggests. In the biggest genomic survey of E.coli to date, that took more than 16 years in Norway, researchers have successfully tracked the spread of antibiotic resistant genes and have demonstrated that these genes are …
