    Cardiovascular problems are a threat in COVID-19. The disproportionate effect of COVID-19 on patients with other cardiovascular issues are not fully understood.COVID-19 infects using the "ACE2" receptor. This receptor if found in many organs including lung, heart and kidney. ACE2 receptors are also seen in endothelial cells. Endothelial cells line the inner surface of blood vessels. The authors demonstrate how these cells are involved in different organs of COVID-19 patients.Patient 1 was a male...

    AbstractGenetics might influence the chance for COVID-19 infection. 2633 volunteers from TwinsUK completed a survey. This allowed a twin study of COVID-19 symptoms.IntroductionThere might be a heritable factor to infectious diseases. The likelihood to get the disease, an immune response, and the severity of the response might be partially genetic. Understanding how symptoms of COVID-19 pass through the population can help allocate hospital resources. The authors developed the "C-19 COVID Sympto...

    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...

    AbstractThis study examines how average temperature (AT) and average relative humidity (ART) relates to COVID-19 cases. This study considers 30 Chinese provinces. There was a strong relation between AT, ART and COVID-19. The correlation was negative. This means that higher AT and ART related to lower COVID-19 cases.When ARH was 67-85.5%%, every 1 °C increase in the AT led to a decrease in the daily confirmed cases by 36-57%%. When AT was 5.04-8.2 °C, every 1%% increase in ARH led to a dec...

    AbstractThe researchers studied wild-type and Arabidopsis thaliana mutants with off-cycle circadian rhythms. The plants that had a matching circadian clock to the light-dark environment cycles had increased growth and survival. For example, these plants fixed more carbon and had more chlorophyll.IntroductionCircadian clocks are the body's biological clock that works to match external light-dark cycles. Circadian clocks give an advantage to organisms. In plants, circadian clock rhythm genes regul...

    Abstract This study explores the influence which psychological pain may have on an individual’s self-harming tendencies. 207 individuals participated, providing socio-demographic information, clinical information, and responding to the Psychache Scale (psychological pain rating method). Covariables such as drug use and patient interactions with psychiatrists were accounted for. Overall findings suggest that psychological pain “significantly contributes in predicting self-harming behaviours.”Intr...

    Abstract This paper shares details about Mitsubishi’s development of a TiAl alloy designed specifically for turbocharger applications (turbine wheels). While some information is dated, the research and development of this alloy was a significant step towards designing modern turbochargers.  Introduction A turbocharger is a device used by many gasoline and diesel power vehicles. It recycles pressurized gases coming from a vehicle’s exhaust manifold, using them to spin a turbine and create positiv...

    Abstract This paper discusses the measures taken in Guangdong, China (most populated province in the country) to curb the spread of COVID-19. Many of the region's recent draconian measures are based on its experience from fighting the 2003 SARS outbreak. Strict regulations combined with extensive healthcare measures resulted in significant day-on-day infection ratio drop offs starting Feb 1st. Introduction China’s early spike in COVID-19 cases makes it a valuable source of information for other ...

    AbstractThis is a retrospective study revealing mortality information about 52 critically illadult patients diagnosed with SARS-CoV-2 in Wuhan Jin Yin-tan hospital. Symptom, laboratory, comorbidity and outcome data was gathered about these ICU patients. Overall findings noted significant mortality for ill individuals over 65 years of age and a frequent need for mechanical respiration.Introduction  The initial spread of the now global SARS-CoV-2 virus was traced back to areas around Wuhan, China....
