7.4f Tumour markers
In health, cell development, growth and death are regulated by complex chemical interactions. In cancer cells, these interactions are disturbed resulting in uncontrolled cell division, tumour development and malignancy. In these cells, abnormal types and levels of substances are produced and secreted into body fluids such as blood. Here, the tumour markers can be quantified by laboratory assay techniques. The ideal tumour marker should * be highly specific and sensitive to a type of cancer * directly reflect the progression of the cancer through the measured level * have a short half life to rapidly reflect treatment * discriminate between benign and metastatic growths * have low levels in the healthy population * have good assay sensitivity
Tumour markers that fit these criteria have an important role to play in the screening, diagnosis and monitoring of cancers. These can be measured qualitatively by histological techniques or quantitatively in biochemistry labs by serological methods.
Screening
No tumour marker is specific or sensitive enough to be used as a definitive screening test for cancer. However, certain tumour markers have proved successful in screening for cancers in high risk populations. This is the case of prostate specific antigen or (PSA) and prostate cancer in middle to late aged men. In China α-fetoprotein (AFP) measurement are used for screening of hepatocellular carcinoma and in the UK faecal occult blood is used to screen for colorectal cancer.
Diagnosis
Tumour markers are not used as the sole determinant in the diagnosis of cancer. The reasons for this are that tumour markers that are meant to be specific for a certain cancer may be expressed in a small percentage of the healthy population and no tumour marker has been shown to be expressed in 100% of a specific cancer type. Therefore,

...Social Science & Medicine 66 (2008) 2520e2531 www.elsevier.com/locate/socscimed Biomedical scientists’ perception of the social sciences in health research* Mathieu Albert a,*, Suzanne Laberge b, Brian D. Hodges a, Glenn Regehr a, Lorelei Lingard a a b University of Toronto Toronto, Ontario, Canada Universite de Montreal, Montreal, Quebec, Canada ´ ´ ´ Available online 11 March 2008 Abstract The growing interest in interdisciplinary research within the Canadian health sciences sector has been manifested by initiatives aimed at increasing the involvement of the social sciences in this sector. Drawing on Bourdieu’s concept of field and Knorr-Cetina’s concept of epistemic culture, this study explores the extent to which it is possible for the social sciences to integrate into, and thrive in, a field in which the experimental paradigm occupies a hegemonic position. Thirty-one semi-structured interviews were conducted to explore biomedical scientists’ receptiveness toward the social sciences in general and to qualitative research in particular. We found that these respondents exhibited a predominantly negative posture toward the social sciences; however, we also found considerable variation in their judgments and explanations. Eight biomedical scientists tended to be receptive to the social sciences, 7 ambivalent, and 16 unreceptive. The main rationale expressed by receptive respondents is that the legitimacy of a method depends on its capacity to adequately...

They also evaluate the effectiveness of treatments. Their work is extremely important for many hospital departments and the functions they carry out are wide ranging. For example, they may work on medical conditions, such as cancer, diabetes, AIDS, malaria, food poisoning or anaemia, or carry out tests for emergency blood transfusions or to see if someone has had a heart attack. Biomedical scientists can work in three areas: infection sciences; blood sciences; and cellular sciences. Infection sciences include: •medical microbiology - identification of micro-organisms causing disease and their antibiotic treatment; •virology - identification of viruses, associated diseases and monitoring the effectiveness of vaccines.

...In 1969, a chemist working with livestock for the CIA was dropping bulls in a new chemical they had created to figure out effects from it. After taking a few notes on the side effects, he slipped into a nuclear stall containing a rotting bull and was enclosed in with the animal. Unknowingly, his fellow scientists pressed a button and fused together the scientist and the bull together. After researchers discovered their accident, they ran a few tests on the hybrid but concluded that he was too unstable to remain alive so they attempted to put him down. Realizing what they had in store for him, he went on a rampage and destroyed everything in his way and using his new cloudy lower body, put the scientist into a horrible trance. He then fled to a nearby rainforest at incredible speed and head-butted a boulder out pure frustration but blacked out and suffered from amnesia. After awakening, he struggled to survive in the wild and only remembers the pain the humans caused him and blames them for his miserable life. As a result, he dedicates his life to seeking out an individual, learning their biggest fear and makes them hallucinate with his cloud lower body until he finds his next target. I believe people still believe in the possibilities of monsters in order to explain the unexplainable. It also releases the bad in us that everyone has which has been proven to help an individual, that’s why we enjoy horror movies so much. The thrill and entertainment of something being dangerous...

Data Scientist Summary

...A data scientist is a relatively new term and job. It implies that one has the ability to make discoveries in the world of big data. D.J. Patil and Jeff Hammerbacher coined the term itself in 2008. Businesses recently have begun bringing in these high-ranking professionals to attempt to make sense of and use the large amounts of data coming to them from various different angles. A well-rehearsed data scientist should be able to do many different tasks. One of those is bring structure to large quantities of formless data. This is important because it brings a sense of ease to business officials that now no longer have to worry about doing this and can focus on more important business decisions. Of course, the now analyzable data would help a business make these decisions. Data Scientists are also able to pair a rich set a data with another rich set or maybe even an incomplete set of data and make it useable once again. This could help with business decisions or even help streamline a website by matching possible friends like mentioned in the article. These scientists also help make the data look visually pleasing by displaying it in different patterns and graphs. With this new form of science they are able to advise managers and higher ups about the implications of certain decisions being thought of by the business. Above all a data scientists’ most universal skill is the ability to write code as they are seen as a hybrid of a data hacker and a data analyst. One last key trait...

Women in Science

...played a part in scientific endeavor, even prior to invention of the term ‘scientist’. Nevertheless, in Western culture, science and femininity lacked unity and the masculine painting of science revealed not only that more males did science, but that science itself was seen as an integrally masculine venture. The notion that mathematics and science were unsuitable or ‘hard’ for women, and even ‘at odds’ with real femininity, can be trailed back to the beginning of modern science and the commencement of the Royal Society in the seventeenth century. Then ‘femininity’ became the exact opposite of the new, masculine, experimental science of Newton and his colleagues who needed to break from the passive, reflective analytical style of outdated ‘natural philosophy’, the former word for science. (Schiebinger, 1996). This divide that detached women from the new experimental science, was made a lot wider by the Nature’s tradition being embodied in female form only. The masculine scientists made ‘mother nature’ their goal of research, and branded her as a female muse who could trick them, but if trained would also permit them to ‘enter her secrets’. This entire trap cast femininity as the inactive, topic of investigation and the male as the virile, enthusiastic investigator; a dualism that just increased the difference between science and femininity (Jordanova, 1991). Regardless of this, there existed women scientists— botanists, mathematicians, astronomers chemists and more—who took part...

The Overview of the Article, the Origin of Old-Earth Geology and Its Ramifications for Life in the 21st Century

...creatures and God replaced them with new living beings. Uniformitarians believed that all geological change happened at the same rate, intensity and power over history. And scriptural geologists believe in the biblical account of a literal six-day creation of all things by God, followed by a global flood which created that geological record.” (Mortenson) The strengths in the article are the differing views presented by various scientists and non-scientists both Christian and non-Christian based. Dr. Mortenson summarized these scientist’s views straight to their points of belief. The points that I found clear was that there was not proof to back the “theories” of the Old Earth views expressed and there was proof of the New Earth view, the Bible. I feel the weakness of the article was that there was not much elaboration on the scientist’s findings. There were a lot Journal Article Review One 3 of names and dates given but not a lot of detail. I feel there should have been more backing information on the views that each scientist or geologist presented. When all you read are names and dates you tend to lose the reader’s attention. I also feel like the author could have had a little more information that was more up to date, such as current studies or studies that have been done more recently. In conclusion, I agree with Dr. Mortenson’s statement made in his article that evolution is not the cause for moral...

...Australian scientists have found a novel way to study whales without killing them. The Japanese authorities claim to base their arguments for whaling on science, but in fact invest heavily in emotive messages - for example, that whaling is an integral part of the national culture • There is no national culture of whaling in Japan; there are local cultures, but there are also local cultures that regard whales as gods, where killing them would be unthinkable • Successive governments have placed a high priority on ensuring a plentiful supply of fish through diplomacy, often building relationships with developing countries possessing productive coastal waters They say analysis of the whales' faeces lets them examine their stomach contents minutely. Japan says the need to find out about the animals' diets is one reason why it kills hundreds of whales every year. The new approach was developed by Australian and US researchers, who collected blue whale faeces in nets. The animals discharge them as a thin brown cloud near the ocean surface. Using DNA testing, the researchers established what the whales had eaten and also a distinctive "signature" for each animal, as well as the internal parasites the whales were carrying. The research was revealed by Dr Nick Gales, a principal research scientist at the Australian Environment Department's Antarctic division. He said: "We will be telling the International Whaling Commission that this is a robust, non-lethal method for...
