The Academy of Sciences of Albania (Albanian: Akademia e Shkencave e Shqipërisë), founded in 1972, is the most important scientific institution in Albania. [1] In the 1980s, several research institutes began at the University of Tirana were transferred to the Academy's jurisdiction. [ 2 ]
Rodents make up the largest order of mammals, with over 40 percent of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Suborder: Sciurognathi. Family: Gliridae (dormice) Subfamily: Leithiinae. Genus: Muscardinus. Hazel dormouse, Muscardinus avellanarius LC; Family ...
The first indications that sex identity could be cell-autonomous rather than entirely hormone-driven arose from studies in non-mammalian species, particularly birds and insects. In the mid-20th century, researchers investigating sexual dimorphism in avian species observed that male and female cells could exhibit distinct characteristics even ...
A mammal (from Latin mamma 'breast') [1] is a vertebrate animal of the class Mammalia (/ m ə ˈ m eɪ l i. ə /).Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones.
The cell on the left is going through mitosis and its chromosomes have condensed. Cell nucleus: A cell's information center, the cell nucleus is the most conspicuous organelle found in a eukaryotic cell. It houses the cell's chromosomes, and is the place where almost all DNA replication and RNA synthesis (transcription) occur.
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (/ ˌ æ n ɪ ˈ m eɪ l i ə / [4]).With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.
To produce viral vaccines, candidate vaccine viruses are grown in mammalian, avian or insect tissue culture of cells with a finite lifespan. [5] These cells are typically Madin-Darby Canine Kidney cells, [6] but others are also used including monkey cell lines pMK and Vero and human cell lines HEK 293, MRC 5, Per.C6, PMK, and WI-38. [7]
In the reticulocyte, as in most mammalian cells, portions of the plasma membrane are regularly internalized as endosomes, with 50 to 180% of the plasma membrane being recycled every hour. [20] In turn, parts of the membranes of some endosomes are subsequently internalized as smaller vesicles.
