Immune responses in COVID-19

SUMMARY: This article review looks at what is already known about SARS and MERS and uses the data and clinical studies to discuss potential vaccines and treatments for the new coronavirus, SARS-CoV-2. Compared to SARS-CoV and MERS, SARS-CoV-2 has a much lower fatality rate (2.8%). It’s highly contagious and has an R0 of 2.2-2.6, meaning… Continue reading Immune responses in COVID-19

The architecture of cell differentiation in choanoflagellates and sponge choanocytes

The architecture of cell differentiation in choanoflagellates and sponge choanocytes SUMMARY: The closest relative to multicellular animals are single-celled organisms called choanoflagellates. These protists look like collar cells. These are cells that have a microvillar ring (the collar) around a flagellum. An example of these cells in animals are sensory epidermal cells. To get a… Continue reading The architecture of cell differentiation in choanoflagellates and sponge choanocytes

Toxic wavelength of blue light changes as insects grow

Toxic wavelength of blue light changes as insects grow SUMMARY: Different wavelengths of light are toxic to insects. In this study, scientists looked at the different effects of blue light on fruit flies (Drosophila). They found that each developmental stage was more susceptible to different wavelengths. There were also differences between males and females. For… Continue reading Toxic wavelength of blue light changes as insects grow

Anhydrobiosis without trehalose in bdelloid rotifers

Anhydrobiosis without trehalose in bdelloid rotifers SUMMARY: There are many types of organisms that can dry out, rehydrate, and then go about their lives with no problems. Many of the larger ones use trehalose or sucrose as an antifreeze. Bdelloid rotifers (tiny microscopic animals) do not. This study looked at the carbohydrate content in desiccated… Continue reading Anhydrobiosis without trehalose in bdelloid rotifers

Chloroplast Division

Chloroplast Division SUMMARY: Chloroplast division in plants is still a fairly unknown topic when it comes to specific cellular/molecular mechanisms. This paper describes, step by step, all the proteins and enzymes involved in helping chloroplasts divide (FtsZ, Min system, ARC6, etc.) It also compares the division of chloroplasts to binary fission in various prokaryotes (FtsZ… Continue reading Chloroplast Division

Mitochondrial respiration during sepsis

Variability of mitochondrial respiration in relation to sepsis-induced multiple organ dysfunction SUMMARY: This is an article review on how oxygen is used by the mitochondrion during sepsis. The role of mitochondria play during sepsis is still inconsistent, despite the various studies that have been done. There are three hypotheses for mitochondrial dysfunction. 1. Mitochondria are… Continue reading Mitochondrial respiration during sepsis
