Satellite images have shown that the biological activity extended to the Indian Ocean and adjacent countries.
Since firmness is a parameter used as indicator of fruit maturation, this study aimed to evaluate the relationship between the biological activity measured by the optical technique of biospeckle laser and pulp firmness of Acrocomia aculeata fruits along the maturation weeks and during the senescence period after harvest.
Interest into the biological activity of ferrocene compounds began when a number of ferrous compounds were patented in 1960s [15].
Bender (atmospheric/ocean and geoscience, Princeton U.) opens by discussing known modulators of climate, such as solar input, landmass coverage influencing albedo, ocean and atmospheric circulation, and atmospheric composition controlled largely by volcanism and biological activity. He then proceeds in chronological order, reviewing what is known from fossil and glacier records about climate during different phases of life on Earth.
According to the contract, Sibelius Natural Products will utilise its biological platform, Chronoscreen, to direct detect, measure and compare biological activity, extension of chronological lifespan, healthspan and toxicity of Creeyan's functional ingredients and formulations, and will also use natural ingredients developed at Oxford to improve the favourable effects of Creeyan's products.
A team of Scottish scientists measured the circadian rhythms, the 24-hour cycle of biological activity, of blackbirds, who reside in the countryside and in urban areas, and found that they differed significantly.
"For many years, scientists have universally agreed that the acetylated polymannan polysaccharides are responsible for much of the biological activity long reported in scientific literature," said Mick Anderson., director of sales for Terry Laboratories.
At least eight vitamin E isoforms with biological activity have been isolated from plant sources.
The Phase 1 study of CDX-301 is a dose-escalating clinical trial aimed at determining the appropriate dose for further development based on safety, tolerability and biological activity. The trial will evaluate seven different dosing regimens of CDX-301 and will accrue approximately 30 healthy subjects at Rockefeller University.
Their biological activity can also be used for classification.
