Researchers identify SARS-CoV-2 antiviral compounds using protein assay

During the process of SARS-CoV-2 infection, once the virus penetrates the host cell, two open reading frames, ORF1a and ORF1ab, are translated. ORF1ab is responsible for the production of 16 nonstructural proteins (nsp). Several viral proteases such as 3CLpro and PLpro (papain-like protease) produce 1-16 nsps. A new study has been published in bioRxiv* preprint server, which deals with identifying drugs that are effective as PLpro inhibitors.

PCR-based reverse genetic system helps analyze SARS-CoV-2 mutations

SARS-CoV-2 is the virus responsible for the COVID-19 pandemic. We know that mutations in the genome of SARS-CoV-2 have occurred and spread, but what effect do those mutations have?

Monitoring CO2 to assess risk of indoor airborne SARS-CoV-2 transmission

In the study, which appeared on the pre-print server medRxiv, the team developed a general mathematical theory to predict airborne transmission risk from carbon dioxide (CO2) time series in real-time and clarify different estimates that steer the guideline. The study findings were based on the assessment of transmission risk and implementing the guideline by CO2 monitoring in university classrooms and office spaces.

Exercise could be used to improve the oral environment in people with NAFLD

Liver disease, from metabolic and bacterial causes, is a growing concern. What connects these dots? The gut, or more specifically, bacteria in the gut.

Study finds a bacterial molecule that may be key to fighting gastric cancer

Humans are exposed to many types of bacteria daily, the majority of which are harmless. However, some bacteria are pathogenic, which means they can cause disease.

BGU researchers identify probiotic yogurt-based drug candidates

Researchers at Ben-Gurion University of the Negev (BGU) have for the first time identified new drug candidates based on molecules isolated from probiotic Kefir yogurt for combating pathogenic bacteria and treating various inflammatory conditions, including inflammatory bowel disease (IBD) and COVID-19 related cytokine storms.

Imbalanced bacterial community in the gums linked to Alzheimer's disease biomarker

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.

Lung microbiome predicts COVID-19 disease severity

A new preprint research paper posted to the medRxiv* server found changes to the lung microbiome during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection influence COVID-19 disease severity.

Researchers unveil new SARS-CoV-2 inhibitor that targets viral immune evasion

In a recent quest for an effective antiviral compound, UK researchers have purified a specific enzyme of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) known as nsp15 and optimized fluorescent biochemical endoribonuclease assays to screen a custom chemical library with over 5,000 commercial compounds. The study is currently available on the bioRxiv* preprint server.

Study uncovers molecular reason why fecal transplants effectively treat C. difficile infections

Experts have uncovered a new molecular reason why faecal transplants are highly effective in treating infections such as C. difficile (a nasty bacteria that can infect the bowel), which could lead to more targeted treatments for this and other similar diseases.

Hay fever and asthma occur earlier in life and affect more people

The unpopular guests are already here. Hazel-, alder- and elm tree pollen sweep in over us during the early spring months, with birch pollen following in May. Then grass follows in June-July before mugwort pollen closes the season in late summer. All leading to more and more people suffering.

Study reveals molecular mechanisms of drug resistance in Mycobacterium tuberculosis

A consortium of researchers from Russia, Belarus, Japan, Germany and France led by a Skoltech scientist have uncovered the way in which Mycobacterium tuberculosis survives in iron-deficient conditions by utilizing rubredoxin B, a protein from a rubredoxin family that play an important role in adaptation to changing environmental conditions.

Hydrogels offer new hope for cancer treatment

Hydrogels are often used as drug delivery systems, but to be effective carriers for anti-cancer drugs, they need to be responsive to varied stimuli in the tumor microenvironment.

Leaky gut and microbial dysbiosis could contribute to cytokine storm in severely ill COVID-19 cases

The gut is a well-established route of infection and target for viral damage by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for COVID-19. This is supported by the clinical observation that about half of COVID-19 patients exhibit gastrointestinal (GI) symptoms.
