Hydroxyzine HCl is a first-generation (sedating) antihistamine and works for itching by blocking histamine receptors.Its anti-anxiety activity is probably due to its effects in certain parts of the brain. This medicine can also cause relaxation of skeletal muscles.ydroxyzine HCl is a first-generation (sedating) antihistamine and works for itching by blocking histamine receptors.
The P. falciparum 3D7 nuclear genome is composed of 22.8 megabases (Mb) distributed among 14 chromosomes ranging in size from approximately 0.643 to 3.29 Mb (Fig. 1, and Supplementary Figs AâN). Thus the P. falciparum genome is almost twice the size of the genome of the fission yeast Schizosaccharomyces pombe.
Paramecium diagram. The parts are as follows: 1) food vacuoles 2) micronucleus 3) oral groove 4) gullet 5) anal pore 6) contractile vacuole 7) macronucleus 8) cilia. Species of Paramecium range in size from 50 to 330 micrometres (0.0020 to 0.0130 in) in length.Cells are typically ovoid, elongate, foot-or cigar-shaped.aramecia were among the first ciliates to be seen by microscopists, in the late 17th century. They were probably known to the Dutch pioneer of protozoology, Antonie van Leeuwenhoek, and were clearly described by his contemporary Christiaan Huygens in a letter of 1678.
