SEARCHING FOR INFORMATION (10 MARKS)


Read the following text and answer the questions 



Treatment For Alcohol Abuse: Experimental drug curbs excessive alcohol use in 

rats


Adapted from chemical and Engineering News

pubs.acs.org/cen/whatstuff/84/8444sci2.html



A new compound synthesized by Eli Lilly & Co. showed such promise in animal tests 

that "it should be developed for clinical use in alcoholism," according to 

neuroscientist Markus Heilig, clinical director at the National Institute on Alcohol 

Abuse & Alcoholism (NIAAA). "We're thrilled, because this has been a dream for 

over a decade for many of us," says Heilig, who led the team that evaluated the 

compound's effect in rats (J. Neurosci. 2007, 27, 2718).



Heilig first found out about the compound, MTIP which showed great promise for 

alcoholism. Heilig's team now has tested MTIP in rats that were genetically predisposed to 

develop alcoholism and in rats that had been trained to be alcohol-dependent. MTIP curbed 

alcohol abuse in both models, "suggesting that it may be effective in treating a broad range of 

alcoholics," says Glenn R. Valdez of Grand Valley State University, in Allendale, Mich.

The compound inhibits binding of corticotropin-releasing factor (CRF) to the CRF
receptor. 

                                                                                1


CRF has long been established as a major regulator of stress in the body and has been linked 

to various psychiatric conditions, including alcoholism, Valdez explains. "Development of a 

CRF
receptor antagonist has been a major goal of many pharmaceutical companies," adds 

   1


Valdez, who studies the role of CRF in alcoholism. But it's been challenging to create a 

small-molecule antagonist that can be taken orally and enter the central nervous system, 

where it can reach the CRF
receptors. The new drug, which is able to cross into the CNS, 

                          1


"seems to show a lot of promise," he says. Most previous CRF
blockers accumulate in the 

                                                            1


liver, potentially causing toxicity, Heilig says. But MTIP is markedly improved in this regard. 

"That's a major breakthrough in the chemistry," he notes.

QUESTION FOUR


VOCABULARY BUILDING (20 MARKS)




In scientific writing, precision is the most important goal of language. As a scien tist 

or engineer, you wouldn't choose the word "weight" when you meant "mass." 

Technical terms such as "weight" and "mass" have specific meanings. If your writing 

does not communicate exactly what you did, then you have changed the work. One 

important aspect of precision is choosing the right word. Another important aspect of 

being precise is choosing the appropriate level of accuracy. 



4. (a)     Select the appropriate word from within brackets. Write the number down 

           and the correct word next to it.



Bees on Patrol:Studies Find Bees Are Potential Chemical, Biological Agent 

Detectors


For the past three years, the Pentagon has been testing honeybees as 4.1 (detectors; 


carriers) for explosives in bombs and biological agents in ambient air. If the 4.2 


(promising; rewarding) test results hold, bees could be 4.3 (utilized; applied) as 


border security sentries and as combatants against agricultural bioterrorism. In work 


funded by the Defense Advanced Research Projects Agency, the University of 


Montana (UM), Missoula, and its many partners are 4.4 (examining; exploring) the 


ability of bees to look for biological agents. These researchers have trained bees to 


sniff    out   4.5   (concentrations;   mixtures) of    explosive   residues   such   as   2.4-


dinitrotoluene and chemical weapons instead of nectar. The work exploits untrained 


bees as flying electrostatic dust mops to detect biological agents over wide areas. In 


these studies, bacterial spores, for example, that have been 4.6 (absorbed; gathered)


on the bees' back hairs are washed off and are eventually 4.7 (measured; quantified)


and identified through culturing or polymerase chain reaction 4.8 (studies; analysis).


It was found that trained colonies of bees were successfully able to 4.9 (verify; detect)


bomb explosives, making bees possible 4.10 (sentinels; agents) against terrorists at 


security checkpoints such as truck stops .                                                          (10)
