RNA methylation (2)

Conditioning as an adjunct in the pharmacotherapy of lupus erythematosus Several studies have provided evidence suggesting that “placebo effects” represent conditioning phenomena and that learning processes influence the response to placebo medication. This case report describes an adolescent with severe lupus erythematosus who received cyclophosphamide (CY) paired with taste (cod liver oil) and smell (rose RNA methylation (2)

RNA-mediated DNA modifications

A new way to discover DNA modifications Excerpt: Using their approach, which combines bioanalytical chemistry, comparative genomics, and a special type of DNA sequencing, the team has discovered a DNA modification that helps bacteria to protect their genomes from viral infection. My comment: There is one way to link nutrient-dependent microRNA flanking sequences from adhesion RNA-mediated DNA modifications

New technique used in report of atomic-level ecological adaptations

Archaerhodopsin variants with enhanced voltage-sensitive fluorescence in mammalian and Caenorhabditis elegans neurons Directed evolution of a far-red fluorescent rhodopsin reported as: New technique uses a genetic tool and light to view and map neuronal circuits Excerpt 1): “This [directed evolution] experiment demonstrates how rapidly these remarkable bacterial proteins can evolve in response to new demands. New technique used in report of atomic-level ecological adaptations

Insect homology and diversity attributed to mutations

Ancient homology underlies adaptive mimetic diversity across butterflies Excerpt: “Surprisingly, our results suggest that modulation of this conserved developmental gene has occurred in tandem between these two deeply divergent butterfly lineages, implying an unexpected and remarkable level of predictability in the evolutionary process.” Reported as: A single evolutionary road may lead to Rome Excerpt: “Copying Insect homology and diversity attributed to mutations

Pulses of olfactory/pheromonal input

Signal and noise: Spike correlations in the olfactory system by John Hewitt Excerpt: “The olfactory system is not so much a hard-wired telephone network where channels can be instantaneously specified and connected by number codes, and then used to transmit further codes. There is significant overgrowth and back-pruning in olfactory networks during development, and some Pulses of olfactory/pheromonal input

Are pheromones responsible for human body odour assessment?

Can You Smell Yourself? by Sarah C. P. Williams on 22 January 2013, 5:10 PM Excerpt: “Other molecules the human body produces could also influence individual smells and scent preferences, Zufall says. The individuality of people’s microbiomes—the collection of microbes living in and on us—could also be linked to the body’s odor or preferences, Wedekind Are pheromones responsible for human body odour assessment?

Evolved development of olfactory systems

how much longer it will be until the “bird watchers” realize that the molecular mechanisms of how olfactory/pheromonal input epigenetically effects adaptively evolved behaviors are the same in species from microbes to man, and species of birds are included.
