Using NAC Against Antibiotic Resistance Bacteria

GwynneL.

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

GwynneL.

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

GwynneL.

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

The Endocannabinoid System of Animals

GwynneL.

The Endocannabinoid System of Animals SUMMARY: This article talks about the endocannabinoid system (ECS) in animals. The first and second section talk about the three parts of the ECS: receptors (CBR1 and CBR2), ligands (endocannabinoids), and the ligand degrading enzymes. The receptors are G-protein coupled receptors, the ligands bind directly to these receptors, and the… Continue reading The Endocannabinoid System of Animals

BCAAs and muscle protein synthesis in humans: myth or reality?

GwynneL.

Branched-chain amino acids and muscle protein synthesis in humans: myth or reality? SUMMARY: This study is an article review on whether or not consuming BCAAs (branched chain amino acids) alone was enough to promote muscle growth. Muscle protein is constantly being synthesized and broken down (anabolism, catabolism). Amino acids in blood plasma come from digested… Continue reading BCAAs and muscle protein synthesis in humans: myth or reality?

Long-term Impacts of Antibiotic Exposure on the Human Intestinal Microbiota

GwynneL.

Long-term impacts of antibiotic exposure on the human intestinal microbiota SUMMARY: This review looked the long-term effects of taking antibiotics. If one is looking at the microbiota as a whole, the effects seem to be short term (a few months); however, if one looks at the population of specific species of bacteria, the numbers don’t… Continue reading Long-term Impacts of Antibiotic Exposure on the Human Intestinal Microbiota
