People across the globe are struggling with arthropod-borne flavivruses, and the treatment of these viruses has so far been very limited. A compound called arbidol (umifenovir) has been seen to counteract the affects of several viruses. The drug is currently being used in Russia and China for the treatment of prophylaxis and influenza. The way arbidol works is by inhibiting the membrane fusion between the virus particles and the plasma membrane of a cell as well as endosome membranes. This basically

Question 1 Names of aquatic plant | Parts and its fuction | Water hyacinth (Eichhornia Crassipes) | The stems and leaves contain airfilled tissue which give the plant its considerablebuoyancy. | Duckweed (Lemnaceae) | Entire lower surface of fronds can absorb nutrients from the medium, and the plants can grow well under conditions which entirely prevent root elongation. | Water Primrose (Ludwigia) | The creeping and floating stems allow it to find open water and sunlight through the larger

the rapid excretion of drugs (Alves et al.2008). Insect succession Insect succession is the wave or pattern of insects’ colonization on dead remains and is also affected by the surrounding environment. Invasion of a body by insects and other arthropods occurs soon after death (Anderson and Goff, 2000). They are capable to arrive and colonized within minutes of the death (Wells and Lamotte 2001). It is not unusual for human remains to be discovered in a highly decomposed or skeletonized state.

Comparing LC50 of Insectisides Pirimicarb and Rotenone on Blowfly, Blowfly larvae, Woodlice and Daphni Abstract The LC50 of insecticides rotenone and pirimicarb were compared by testing blowfly, blowfly larva, woodlice and daphnia. Rotenone is a NADH dehydrogenase inhibitor causing death by oxidative stress however pirimicarb causes toxicity through acetylcholinesterase inhibition. It was found that rotenone had large toxic effects on daphnia, blowflies and woodlice but not maggots and pirimicarb

Urticaria : definition/ diagnostic criteria Urticaria is described by the quick manifestation of wheals and this may be accompanied by angioedema. A wheal has three typical features which comprises: (i) a centrally located swelling of varying size, almost always encircled by reflex erythema; (ii) accompanied with itching or burning and; (iii) its transient nature, where the skin returns to normal appearance within 1 hour to 24 hours. (1) The transient nature of urticaria is an important characteristic

All invertebrates will have different circulatory systems, but they will have one of the main three. Therefore they should have either a closed/open circulatory system, use diffusion, or have the water vascular system. In a more primitive creature such as the starfish, they use the water vascular system. Because of this, their circulatory system is very basic, it flows water into them through their madreporite, then out through their tube feet. Thus, this aids them in movement, but they move very

Introduction The Daphnia magna, more commonly known as the water flea, is a tiny freshwater crustacean. Its clear exoskeleton and jointed appendages point to its classification as an arthropod. This is further evidenced by the location of its heart—the dorsal region. The Daphnia magna’s importance in the aquatic food chain can be attributed to its essential place in the diet of young and adult fish (Elbert, 2005). The Daphnia magna belongs to Class Branchiopoda, which are free-floating crustaceans
