The single-celled parasite, Plasmodium falciparum, causes malaria, was responsible for 214 million cases and 438,000 deaths globally in 2015, of which 88% of cases and 90% of deaths occurred in sub-Saharan Africa. The morphology of P. falciparum is characterized by numerous rings (young trophozoites) and the absence of mature trophozoites and schizonts. In a P. falciparum blood smear, multiple infected erythrocytes appear more often than in other species and the rings of the parasite in the blood smear tend to be smaller than other species. Distinctive crescent-shaped gametocytes appear late in the infection. In vitro cultivation of P. ...

Vid30 complex participation in the degradation of CDC25 in yeast and their role in Ras/ cAMP/ PKA pathway

Background: Unicellular organisms such as Saccharomyces cerevisiae in its total life cycle is exposed to diverse and changing nutrient conditions. Thus, in order to survive and achieve a competitive advantage, it has adapted itself such that it not only uses the wide range of available nutrient sources but also the sources that are nutrient rich. It mainly uses fructose and glucose by rapidly fermenting to alcohol. In response to these nutrient conditions, the intracellular trafficking transcription and turnover of protein from nutrient transporters (e.g. Hxts) get regulated. Therefore, when the availability of the glucose increases, the expression of low- ...

Part 1:

There are several analogies between the biological cellular structures evolution and the individual corporation development. A prokaryotic cell is a cell with no internal organelles; all the functions of the cell are distributed randomly inside, similar to a small company where all the members of the enterprise execute the functions of production, administration, and management. There are no specialized duties between the members of the organization similar to the lack of specialization in all the volume of the prokaryotic cell. In a eukaryotic cell (Diffen, 2014). There is a presence of internal organelles that execute specialized functions ...

Paramecium is a unicellular organism belonging to genus, Protozoa. Like many other Protozoa, paramecium has ciliated body that aids in locomotion. The habitants of protozoa vary from fresh water bodies, marine water, brackish and stagnant waters in in basins and ponds, (Ladenburger 7). Some species of paramecium can easily be cultivated and induced to conjugate. Due to these characteristics, paramecium has been used in laboratories for research purposes. The body of a paramecium is covered by cytoplasmic structures which are called cilia. Cilia are hair like structures which helps the organism in movement. The flickering movement of cilia propels ...
