The animals with the mutation fell off a rolling log much
sooner than the control animals did, which suggests that the mutation left them much less tolerant to alcohol's effects.
Infusing the mice with massive numbers of these plasmids under high pressure left the animals with up to 92 % less hepatitis B
RNA than control animals, the researchers report in the 12 May issue of Nature Biotechnology.
A day after fear training, animals whose brains were injected with a virus engineered to carry a «sponge» against miRNA - 34a froze less
often than control animals.
The mice that received dengue or West Nile antibodies also had higher levels of Zika virus in their testes and spinal cords
than control animals did.
Mice that were previously exposed to early - life stress performed
worse than control animals and demonstrated poor learning and memory skills.
When fed a standard soybean diet, the transgenic pigs excreted up to 75 % less
phosphorous than control animals, the researchers report in the August issue of Nature Biotechnology.
The microbiome did modulate the immune system: the animals grown in germ - free conditions expressed complement genes at lower levels in the
skin than control animals.
In an operant test R6 / 2 transgenic mice (240 - CAG repeats, B6 congenic background) were less able to acquire lever
pressing than control animals at an age where motor function is only mildly affected (from 9 weeks), with this deficit being both more pronounced and detected earlier (from 5 weeks) where reinforcement was not solely contingent on responding.
Animals that were also given a plasma kallikrein inhibitor, and animals that were genetically modified to produce lower amounts of the protein, showed significantly less bleeding, brain swelling and damaged brain
areas than control animals without plasma kallikrein blockade.
After 30 days, when rats were again given the opportunity to press a lever for water, those who had become dependent on sugar pressed the lever significantly more
times than control animals, suggesting impulsive behaviour.
After a month, the animals taking either dose of Methylsulfonylmethane had developed less degeneration of the cartilage in their
knees than the control animals.
The verdict, from a 25 - year study in rhesus monkeys fed 30 % less
than control animals, represents another setback for the notion that a simple, diet - triggered switch can slow ageing.
In addition, these mice had more GluN2B — a subunit of NMDA —
than control animals.
