Lending color to dead cells -- A novel natural dye for screening cell viability
Thu, 24 Sep 2020 00:00:00 EDT
(Tokyo University of Science) Synthetic dyes are commonly used to assess the toxicity of chemical compounds in cell cultures. However, these dyes damage cells, rendering the cultures useless for long-term experiments. Recently, scientists from Japan discovered that a natural food pigment can replace synthetic dyes in cell viability assays for three widely varied types of cells--and performs better. Their approach is also environment-friendly and inexpensive, and opens up possibilities in a range of fields including drug discovery.

Hypercoagulability in patients with coronavirus disease (COVID-19)
Thu, 24 Sep 2020 00:00:00 EDT
(American Roentgen Ray Society) In this AJR article, 82 patients with COVID-19 who underwent abdominal ultrasound or CT were retrospectively compared with 82 patients without COVID-19 for thromboembolism and solid-organ infarction. Nine (11%) patients with COVID-19 had thromboembolic findings, with medium to large arterial thrombi in five. One patient without COVID-19 had known portal vein thrombus on CT. Thromboembolic findings occurred more frequently in patients with than without COVID-19 (p = 0.02).

Carriers of two genetic mutations at greater risk for illness and death from COVID-19
Thu, 24 Sep 2020 00:00:00 EDT
(American Friends of Tel Aviv University) Tel Aviv University researchers suggest that carriers of the genetic mutations PiZ and PiS are at high risk for severe illness and even death from COVID-19. These mutations lead to deficiency in the alpha1-antitrypsin protein, which protects lung tissues from damage in case of severe infections. Other studies have already associated deficiency in this protein with inflammatory damage to lung function in other diseases.
Older the person, higher the self-esteem: age differences in self-esteem in Japan
Thu, 24 Sep 2020 00:00:00 EDT
(Tokyo University of Science) Self-esteem, or the value one assigns oneself, changes through life. Studies from western countries report a decline in self-esteem post-60 years, but studies in Japan have not sufficiently explored this, owing to partial perspectives on self-esteem and not investigating people aged 70 and older. Now, a new study by Japanese researchers examines the relationship of self-esteem with age and presents an analysis of web-based surveys, expanding our understanding of self-esteem.
