Study suggests sewer rats immune to SARS-CoV-2

Although the researchers found that the rats tested negative for the virus, they say it is important to continue monitoring animals for the virus as it mutates, making previously resistant species susceptible to infection.

New, easy-to-perform test can rapidly detect widely circulating SARS-CoV-2 variants

Rutgers researchers have designed a new rapid test that can detect all three of the rapidly spreading variants of the coronavirus in a little over one hour – much shorter than the three to five days required by current tests, which can also be more technically difficult and expensive to perform.

Researchers explore 3D printing materials to print realistic aorta models

Personalized 3D printed models created from cardiac imaging data, mainly from cardiac CT images have been increasingly used in cardiovascular disease, primarily in the preoperative planning and simulation of complex surgical procedures, as well as medical education.

Current vaccines and therapies may be less effective at neutralizing new SARS-CoV-2 variants

A new study of the U.K. and South Africa variants of SARS-CoV-2 predicts that current vaccines and certain monoclonal antibodies may be less effective at neutralizing these variants and that the new variants raise the specter that reinfections could be more likely.

How do viruses evolve in bats?

Bats have played a crucial epidemiological role in the evolution of many viruses and house many coronaviruses. Until 2002, coronaviruses had been known to cause mild respiratory ailments in human beings. However, this notion changed in the same year when a bat-borne virus caused the severe acute respiratory syndrome (SARS) pandemic.

Self-assembling nanoparticles an effective vaccine candidate for SARS-CoV-2

The currently developed vaccines against SARS-CoV-2 include the RBD in their immunogen. With a similar objective, a new study developed an RBD protein-based vaccine candidate against the SARS-CoV-2, using self-assembling Helicobacter pylori-bullfrog ferritin nanoparticles as an antigen delivery system. The study is published recently in the journal mBio (by the American Society of Microbiology).

New findings could help speed the treatment for UTIs in children

A study led by UT Southwestern and Children's Health researchers defines parameters for the number of white blood cells that must be present in children's urine at different concentrations to suggest a urinary tract infection (UTI).

Regular intake of oily fish can help prevent cardiovascular disease in high-risk individuals

An analysis of several large studies involving participants from more than 60 countries, spearheaded by researchers from McMaster University, has found that eating oily fish regularly can help prevent cardiovascular disease (CVD) in high-risk individuals, such as those who already have heart disease or stroke.

Study shows persistence of marijuana THC in breast milk for six weeks

In a new study published in JAMA Pediatrics, researchers at Children's Hospital Colorado have found that tetrahydrocannabinol (THC), the psychoactive component of marijuana, stays in breast milk for up to six weeks.

Sniffer dogs could be used to detect SARS-CoV-2 infections, say researchers

Researchers in Germany suggest that sniffer dogs should be considered as an additional screening tool for detecting infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).
