Using NAC Against Antibiotic Resistance Bacteria

sciencewithevie

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

Sexual reproduction in parasitic protists

sciencewithevie

Sexual reproduction and genetic exchange in parasitic protists SUMMARY: Sexual reproduction is often murky in parasites because it’s difficult to observe. There are two other ways to determine if an organism has sex: differences in genomes and genes for meiosis. However, in parasites, there are exceptions to this rule in that some organisms may have… Continue reading Sexual reproduction in parasitic protists

Chloroplast Division

sciencewithevie

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

Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality

sciencewithevie

Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality SUMMARY: Researchers compared the genomes of two ciliates: one known to have sex, and another that has not been observed to have sex under laboratory conditions. Genes for meiosis were found in both classes of ciliates. Also, structures such as the micronuclei and macronuclei indicate that perhaps… Continue reading Meiotic Genes in Colpodean Ciliates Support Secretive Sexuality

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

sciencewithevie

Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers SUMMARY: This article talked about using soil eutardigrades and bdelloid rotifer primers to quickly and easily identify these organisms directly. Due to the fact that there are so many types of microorganisms in soil, many of which are still unidentified and unable to be cultured in… Continue reading Environmental DNA sequencing primers for eutardigrades and bdelloid rotifers

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression

sciencewithevie

Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression in a mouse via the vagus nerve SUMMARY: This study looked at the effects of Lactobacillus rhamnosus on GABA receptors and the role of the vagus nerve in the gut-brain connection. Results showed that L. rhamnosus decreased cortisone levels in stressed out mice… Continue reading Ingestion of Lactobacillus strain regulates emotional behavior and central GABA receptor expression
