Study Of The Visual Adaptation Mechanism In Marine Species With The Change Of Habitation Depth., Demid Osipov, Daniil Moshnikov
The International Student Science Fair 2018
The goal of our work was to determine the principal mechanisms that provide the difference in visual perception of two marine species that live on different depths: T. Pacificus and O. Vulgaris. In nature, visual perception of species that live deeper is shifted towards the blue region. This is related to the fact that red, orange and yellow light is absorbed more strongly by water than the blue light. On the other hand, the visual perception spectrum of an animal is determined by the absorption spectrum of the "light sensor" located in rods and cones of its eye retina. These …

The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa
The International Student Science Fair 2018
Astrocytomas, from cell line 1321N1,are cancerous astrocytes. These are a type of glial cell in the brain which is responsible for maintaining synaptic contact and the signaling capacities among neurons. They also represent a fundamental element in controlling blood flow and defining brain micro structure. Due to the fact that this variant is cancerous, a condition commonly described as an abnormal cell cycle and uncontrolled reproduction of cells, they have the ability to metastasize.
In the metastatic process of cancer cells the initial phase is know as tumor invasion. This stage consists mainly of the cells migrating away from the …
