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

Using NAC Against Antibiotic Resistance Bacteria

N-acetyl Cysteine Coated Gallium Particles Demonstrate High Potency against Pseudomonas aeruginosa PAO1 SUMMARY: Antibiotic resistant bacterial infections are on the rise, especially in hospitals. One of the culprits is the bacteria Pseudomonas aeruginosa (POA1). Researchers are quickly running out of antibiotics to use against resistant strains. The problem has reached the point where colistin, a… Continue reading Using NAC Against Antibiotic Resistance Bacteria

Different Enzymes to Digest Different Plant Substrates

The fungal cultivar of leaf-cutter ants produces specific enzymes in response to different plant substrates SUMMARY: Leaf-cutter ants and a fungus called Leucoagaricus gongylophorus have a symbiotic relationship. The ants harvest plant material for the fungus to “eat” and then the ants feed off of the gongylidia. These swollen parts of the hyphae are no… Continue reading Different Enzymes to Digest Different Plant Substrates

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

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
