But a team of Swedish researchers has uncoveredevidence that worms do indeed feel pain, and that worms have developed a chemical system similar to that of human beings to protect themselves from it. The Swedish scientists, J. Can blood worms infect humans? If a deerfly eats infected blood fr...
Are pinworms part of the phylum Platyhelminthes? Are members of the phylum Platyhelminthes acoelomates or coelomates? Do members of the phylum Nematoda have a hydroskeleton? Segmented worms are classified in which phylum? Are members of the phylum Platyhelminthes parasites in humans?
The hypertension drug rilmenidine has been shown to slow down aging in worms, an effect that in humans could hypothetically help us live longer and keep us healthier in our latter years. 研究表明,高血压药物利美尼定能延缓蠕虫的衰老,这种作用在人类身上可能能够帮助我们延长寿命,使我们在晚年更加健康。
Filarial worms are nematodes or roundworms that dwell in the subcutaneous tissues and the lymphatics. Although eight filarial species commonly infect humans, six are typically considered blood borne, in that the parasite stages infectious for the vector reside in the blood. These are the causative...
Oxygen requirements have played a major role in determining both the composition of blood and the architecture of the circulatory system. In some simple animals, including smallwormsandmollusks, transported oxygen is merelydissolvedin the plasma. Larger and more-complex animals, which have greater oxyg...
in those who are infected with the fish tapeworm Diphyllobothrium latum or have intestinal cul-de-sacs or partial obstructions where competition by the tapeworms or by bacteria for vitamin B12 deprives the host, and in persons with primary intestinal diseases that affect the absorptive capacity...
The heart is one of the first organs in an embryo to develop, and the first to be functional. In humans, heart beat starts early during the third week of development (postfertilization), to generate a unidirectional blood flow by the end of this week. The heart develops as a specialized...
In this work we focus on one key schistosome species infect- ing humans, Schistosoma mansoni; we examine extracel- lular and intracellular enzymes of these worms that are involved in the metabolism of riboflavin (vitamin B2) and its key metabolites, flavin mononucleotide (FMN) and flavin adenine...

C. elegans has several other benefits for studying heme transport. Hamza's team could control the amount of heme the worms were eating. With only one valve controlling the heme transport, the scientists knew exactly where heme was entering the worm's intestine, where, as in humans, it is ...
