Evaluation Of Leukocyte Transcripts In Killer Whales By Tatjana Sitt

546 Words3 Pages

The experiment that the article “Longitudinal evaluation of leukocyte transcripts in killer whales” by Tatjana Sitt was based on is about different factors that are responsible for illnesses and stressing of domestic and wild killer whales. The research was conducted on 26 “clinically healthy” whales that contributed a total of 232 individual samples. After RNA extraction, cDNA synthesis, and Real- time PCR analysis the scientists found that the IL-4 transcripts were often absent, and the IL- 17 transcripts were often found in the outlier population of the graph. The scientists conducted this experiment to further apprehend the immune system and the immediate longitudinal health of cetaceans. They sampled the domestic killer whales, and found though the blood leukocyte transcript analysis was a possible option for larger diagnostics there was no actual tie between transcript levels and animal health (Sitt 14-15). …show more content…

By conducting this study humans are expanding their knowledge of creations immune systems. That’s what biology is all about- studying life! Because of this one experiment we are able to advance diagnostics and treatments for orcas. The ocean is a mystery, and a lot of the animals that inhabit it are as well. These seemingly small advancements are actually quite the victory. The more we can understand about marine life, the more we are advancing as an educated

Alexa’s mission excludes secrecy because of molecular biology, swabbing DNA, and curiosity. Under those circumstances, Alexa went back to the molecular biology lab to find a way to determine the relations between the dolphins. She became more interested in Molecular Biology and her father became excited that Alexa finally took interest in Molecular Biology. “To help feed her curiosity, he faxed several papers to her” ( Chapman,

A planned multi-million-dollar offshore aquarium off of Granite Island is being fast tracked with hopes of reviving the tourism region at Victor Harbor (ABC, 2015). While it is early days in the proposal, there is an air of confidence that the plan will precede if the community accepts the idea (Simmons, 2015). What impact will the proposed underwater observatory have on Victor Harbor? To assist with the research Simone from the Port Lincoln Swim with the Tuna observatory was contacted as well as Oceanic Victor and an interview was held with Ian Milne, the marine biology teacher at Victor Harbor High School. Research was also conducted at Granite Island.

A biological oceanographer Paul Falkowski from Rutgers University lectured in his conference on marine biotechnology that it is fundamentally idea-limited. Marine biologists always work with their favorite organisms to value and learn its sentiments of marine. So his speech pointed out that “Markets are not sentimental!”An anthropologist Sylvia Yanagisako argued about capitalist that enterprise fundamentally involves sentiment including economic action with capital accumulation, firm expansion, and diversification’, one remarkable instance came in to pass about floating blue-green algae plantships. Finally, this talk came into existence by elderman statement in Hawaii by Patrick Takahashi, that this ocean species depends on the plankton for

Summary: The article begins with Miller, who is a wildlife pathologist and veterinarian, spending days doing autopsies on dead animals. The cause of these deaths, Sarcocystis neurona, a single- celled parasite that comes from opossums. This pathogen along with many others have been causing many wildlife to fall ill and sometimes die. Solomon writes, "The most studied terrestrial pathogen currently affecting sea animals comes courtesy of America's favorite house pet, the cat" (Solomon 74).

Dillard states, “I want them to think about the fact all of this is in the ocean, and I want them to think about the fact it’s not going away” (Newsminer 2015). One person commented on McKenzie’s article, “Education on this subject is the only way to help diminish marine debris, as many people are unaware of the scope of this issue.” This commenter obviously understood what McKenzie was trying to create, awareness not just art. Although this art will never be able to clean all the debris that have entered our oceans it is a wonderful way to raise education that is interactive and catches peoples eyes in a positive manner and may help decrease further marine

This article from Killer Whale. Org is an informative document detailing information regarding the killer whale species. This article includes information about their origin, habitat, culture, social structure, and the captivity trade. This source is trustworthy because the information that is within the article directly comes from BioExpedition, a publication that contains factual data from noted scientists and biologists in the field. This source is also trustworthy because the research that has been conducted has been vastly accepted as fact by the marine biology community.

So why do people used to kill whales in the 1800s? Well it's was because of one very important item which is oil. Whales had 25 tons of oil and soon everything about the whale was used to the flesh to the bones. During the 1850s, a certain man literary saved the whales. His name was Abraham Gesner who was a canadian physician and geologist.

This research is unfair and animals in this test don’t understand anything that is going to happen to them. Furthermore, animals “suffer painful procedures and isolations”(Source A) that really impacts the way scientists are saving human lives. However if we don’t stop animal testing, we could save lives but we won’t be helping the innocent animals the could be endangered and-and almost instinct. There are also alternatives that scientist could use to see if the product they have created could impact human lives. I think that if scientist test one cell organisms they could find the result of the experiment and see what could impact the entire body of a human or an

In 2000, a mass stranding of whales in the Bahamas revealed hemorrhaging near the brain, ear, and fats in the head from a sonar used by the U.S. Navy during an exercise (National Oceanographic and Atmospheric Administration and US Department of the Navy 2001). In 2002, another stranding occurred in the Canary Islands and pathologists examined the bodies of stranded beaked whales to reveal hemorrhaging in the same areas of the head as the whales from the Bahamas, as well as in the kidneys (Fernández et al. 2005). Upon further inspection, there seemed to be other complications, such as lesions and embolisms, in the vessels and tissues surrounding organs. Fernandez et al.

Herman Melville’s book titled Moby Dick is an obsession with whales. Melville suggested in his book that the whale represented the man’s relationship with the world and his experience of whale hunting was a thing of capitalist. He also depicted whales as harmonious creatures and the ocean was sometimes depicted as pleasant. He explained his experience as a whale hunter as a good thing as it enable humans involved to appreciate the beauty of sea creatures but on the other hand it was not a good thing for the environment. These real life experiences and peoples’ histories with the Pacific helps us the importance of whales and the danger of whaling hunting in the Pacific environment as whales are important in the ecosystem.

You must have patience because when doing test results on an animal or if your studying an marine organism, it takes days for the results to come in. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its environment. I have learned that when being a marine biologist it takes lots of patience when observing your animals and also when doing test on marine mammals. In conclusion, Marine biology is an important part of all marine life. Marine biologist study and observe fish, dolphins, seals, and other mammals to help the people and also themselves to find new and efficient ways to help

Leukemia used to be a death sentence with a survival rate of 4%, but now, because of testing, there is an 80% chance of survival. These odds are much more pleasant than the ones before research. People have gotten help for many diseases because of the research and testing done on animals. Not only does testing help humans, it also leads to developing life saving medical treatments for animals as well.
