Lauren Kelly Individual Student Presentation 28 July 2013 Toxic Plants 10. Would you believe that there’s a tree so poisonous that you don’t actually have to touch it to be harmed? It’s called the manchineel tree (found throughout the Florida Everglades‚ Central America and the Caribbean. Inhaling sawdust or smoke tree may result in a variety of uncomfortable side effects‚ including coughing‚ laryngitis and bronchitis. Some reports suggest that simply standing beneath the tree during a rainstorm

Rehabilitation of vegetation is single and most important process among physical‚ chemical and biological mode for the restoration of degraded soils (Zhou et al.‚ 2003). Castor bean (Ricinus communis L.) is not only important oilseed crop but also has tolerance to many abiotic stresses like heavy metal‚ salinity and drought (Babita et al.‚ 2010; Bauddh and Singh‚ 2012b). These properties of castor bean make them a capable candidate for amelioration of such soils with some value added benefits like

“Once in awhile things slip” this is the statement said by the butcher in death of a pig. In the story he spent several day and nights in mid-September tending to an ailing pig. In depth he talked about how he could have died‚ and the pig could have lived he felt like he should have accounted for the stretch of time and that if he died and the pig lived no one would have been left to do the accounting? In a way he treated the pig like a child tending to its sickness‚ and getting sick in the process

Cell Bio Bites Topic: Ribosomal Function and Ricin Relevance of Ricin and Ribosomes Relevance of Ricin and Ribosomes Most foods from the four food groups contain protein. Protein is manufactured by the ribosome. In contrast to ribosomes‚ ricin breaks up proteins and blocks protein synthesis. In that perspective‚ ribosomes can be seen helpful and ricin as useless and lethal to a somatic cell. Luckily‚ since ricin can stop protein synthesis‚ ricin is being experimented to block diseases’ protein

Ricin is a toxic protein found in castor oil plant seeds. The toxicity of Ricin has been known for centuries and was even used by the KGB government to assassinate Georgi Markov‚ a famous journalist who openly criticized the Soviet Union’s communist regime. The toxicity of ricin is caused by its ability to deactivate ribosomes and halt protein synthesis. Therefore‚ Ricin is categorized as a ribosome inactivating protein (RIP). There are two types of RIPs: type I and type II. Type I RIPs are usually

“What is a poisonous plant‚” one may ask. A poisonous plant is a something that is a toxic and can be harmful to humans‚ animals‚ and even insects. Poisonous plants exist because they may benefit a species‚ but may also be harmful to others. Many noxious plants can result in immense pain‚ sickness‚ disease‚ and mortality. Some of these plants include: the Atropa Belladonna‚ Brugmansia‚ and Ricinus Communis. The Atropa Belladonna emanates from Eurasia‚ which is located northeast of the United States

intentional release of biological agents. It is also known as germ warfare (Medicine Net). Some common‚well known biological agents are bacillus anthracis‚ variola major‚ and ricinus communis. These agents are better known as anthrax‚ smallpox‚ and ricin (Medicine Net). These are just three of the biological agents. Bioterrorism has been around since the fourteenth and fifteenth centuries (Pbs.org). People back then would load diseased corpses onto catapults and launch them at their enemies. It was

The use of biological agents in bioterrorism is a topic that generates strong reactions and many opinions. While the use of these agents is not new‚ the increasing level of use in wartime situations is becoming more of a reality. Because biological agents can be relatively cheap to manufacture and can be easily hidden until time to use‚ they have become a real threat to our world. It is important to understand the history of this form of warfare and identify the most widely used agents so that

it because it leaves behind little or no trace of its use on a victim. Ricin is a naturally occurring protein derived from the beans of the castor oil plant‚ Ricinus communis. Ricin is highly poisonous if inhaled or injected‚ but less so when ingested. When inhaled or injected‚ just a few grains of it can kill an adult‚ due to its high toxicity: refining the pulp of as few as eight beans can create a dangerous amount of ricin. The median lethal dose is roughly 22 micrograms per kilograms in humans

Are Judges Manipulative Courts have a certain system that one would expect that everyone would adhere to. Unfortunately‚ it seems as if judges have their own agenda. Stare decisis is supposed to be adhered to but judges like to put their own spin on things. Precedents are like word games to judges. They love to play around with them and change them to their liking. Judges use judiciary interpretation to manipulate the law by deciding that the precedent is sufficiently different from the
