    Abstract The U.S. used the northern Marshall Islands to test nuclear weapons between 1946 and 1958. The radioactivity may still be present from the decay of cesium-137. The authors studied six islands. All islands had radioactive islands that were within safety standards except for Bikini Island. Some islands still had some radioactivity. Bikini Island had excessive and unsafe gamma radiation. Further research needs to find if radiation exposure through food ingestion or other ways make habitati...

    Introduction Other scientists in the field have already put forth several models for the structure of deoxyribose nucleic acid (DNA), but there are errors in their models. Some errors are the lack of hydrogen bonding and the repulsion of the phosphate groups. Aims Watson and Crick propose a model for DNA structure.Methods X-ray crystallography images give clues to the shape of the DNA molecule.ResultsIn the model, DNA consists of two chains coiled in a helix around one axis. The ad...

    NoteDcyphr summaries are not a substitute for medical advice. Always consult your physician before taking any new drugs or changing your diet in any way. The data on the current COVID-19 outbreak is also changing, so there may be updates.AimsThe authors aim to explain the origins of chloroquine and its current use. They expand what this means for the current COVID-19 outbreak.SummaryDrug repositioning is finding an alternative use for another drug. Drug repositioning has gained momentum in recen...

    NoteSummaries from dcyphr do not substitute the advice of health professionals. The information on COVID-19 is constantly changing. Also, this study has an extremely low sample size, and more research needs to be done.Abstract Researchers detected the 2019 novel coronavirus in 11 out of 12 (91.7%%) of patients. Saliva taken incrementally showed a decrease in virus concentration with time. Viral culture indicated the presence of live viruses. Saliva testing is promising for detection of 2019-nC...

    AbstractShear behavior is how a material reacts to a stress or strain that occurs due to a force parallel to a surface. The researchers mixed recycled concrete aggregate (RCA) and fine or coarse crumb rubber. The researchers conducted shear tests with mixtures of RCA and rubber in different proportions. They find that adding rubber increases cohesion of the mixture. But if you add more than 0.5%, it decreases the cohesion. They try to create a model to predict the shear strength of the mixture....

    Abstract The soil in tropical forests contain about ⅓ of the world’s carbon in soils. Scientists predict that global warming will cause soil instability, leading to the release of carbon dioxide (CO2). The extra CO2 release will worsen climate change effects. The researchers test this theory by experimentally warming the soil in Barro Colorado Island, Panama. They found massive amounts of CO2 emission after two years. Meanwhile, other factors that may affect the soil carbon, such as microbial or...

    AbstractIn February 2020, there were available tests for IgG and IgM antibodies for SARS-CoV-2 (severe acute respiratory syndrome coronavirus). The National Health Commission of the People’s Republic of China added serological tests as a diagnostic criteria for COVID-19. Previous studies show there is no evidence of antibody transmission from mother to infant for mothers with COVID-19. In this study, they added serological tests to examine how newborns are affected.MethodsResearchers took throat...

    Abstract:COVID-19 is an acute respiratory tract infection. Understanding where exactly the SARS-CoV-2 virus replicates and infects within the body is important in trying to contain the virus. The paper reports, based on review of nine cases, that the SARS-CoV-2 virus can replicate in upper respiratory tract tissues. Active replication in the throat was confirmed by the presence of viral replicative RNA in throat samples. Significant amounts of virus can still be found in the sputum (phlegm) of p...

    Abstract  Understanding the severity of COVID-19 is crucial for proper healthcare. A simple approach to assessing disease seriousness is presented. The reference group consists of influenza patients with pneumonia from German hospitals. It was found that there were more deaths among COVID-19 patients without underlying conditions than in the reference group.  Methods  The assessment of the seriousness of COVID-19 was generated by comparing well-described cases from hospitalized COVID-19 patients...

    Abstract This paper analyzes the effect New Jersey’s decline in horse racing has on the state’s veterinarians. More specifically, the study looks on several veterinarian practices’ revenue and staff size over the last five years. The data gathered suggests that only veterinarians involved in racehorse breeding (vs those in horse racing) were negatively impacted by the industry’s decline.  Introduction New Jersey’s share in the $122 billion dollar equine industry was estimated at $1.1 billion in ...
