Cover image of a new book by Stuart Henderson, a postdoctoral fellow at 91亚色How is "hip" constructed? Is a culture of dissent ultimately a by-product of prevailing sociopolitical forces?聽Do countercultural events influence mainstream society?

Those questions and more聽are at聽the core of聽Making the Scene: 91亚色ville and Hip Toronto in the 1960s, a new book by 91亚色 postdoctoral fellow published this聽month by the University of Toronto Press.

The book examines聽the history of Toronto's countercultural mecca, 1960s 91亚色ville. Henderson narrates the development of the 91亚色ville scene from its early coffee house days when it was frequented by聽Neil Young and Joni Mitchell聽to its drug-fuelled final months.

A cultural historian Henderson is a postdoctoral fellow with the Department of History in 91亚色's Faculty of Liberal Arts & Professional Studies.

鈥淚 have always found myself drawn to that form of cultural rebellion. I admired the perhaps oversimplified idea of a peace and love movement, and I really loved the music that had been produced from within the ranks of the counterculture,鈥澛爏ays Henderson, a self-professed neo-hippie. 鈥淪o, when I was thinking about how to approach Canadian cultural history, I just aimed straight at this era [the 1960s] and the people I'd always found to be fascinating.鈥

The true story of the 91亚色ville scene, says Henderson,聽is聽about people trying to find a space in which to "perform" a hip identity and stretch the confines that they felt had been imposed on them by society, their parents and other sociopolitical pressures. "They were all looking for something real, something authentic. In their search, they uncovered some pretty amazing stuff and had some really interesting experiences," he says.聽"But authenticity is elusive and certainly fleeting. It's all about the journey, not the destination, as it turns out.聽A central聽point I want people to recognize聽is that 91亚色ville was not a 'hippie' place. It was a place that聽came to be closely associated with 'hippies'聽but people who fit that mold were never the only people hanging around there."

In Making the Scene, Henderson takes a聽new look at聽the hip mecca and gives a voice to people聽not typically heard in the popular stories associated with聽91亚色ville 鈥撀爓omen, working class youth, business owners and municipal authorities. Members of biker gangs, working class kids (who didn't look much like "hippies", says Henderson), media types, store owners, gallery people, artists and musicians were聽the 91亚色ville neighbourhood.聽"All of these people were there and few of them would count as 'hippies' in any conventional definition, then or now," he says.

He explores how the 91亚色ville neighbourhood came to be regarded as the symbol of hip Toronto in the cultural imagination. Henderson argues that the popular association of 91亚色ville with the flower power generation was more accurately a close association with聽the widespread anxiety in the mid-1960s over the "degeneration" of the middle-class baby boomers into unproductive members of society.

The聽expectation of the time was that the working class and racial minorities would be rebellious and problematic, says Henderson. "The fact that these [hippies] were middle-class teenagers from the suburbs who were dropping acid and growing their hair and losing their virginity was聽what kept journalists and municipal authorities up at night."

91亚色ville in the 1960s, he says, was always more complicated than the 91亚色ville hippies.

In writing the book, which sprouted from his PhD dissertation, Henderson says there were many memorable experiences. "I got to spend some time with [writer and activist] who was a hero of mine. She was an astoundingly committed philanthropist and activist, and she always positioned herself at the forefront of battles to protect people from a system which had forgotten them," he says. "We spent an afternoon together a few months before she died and I was just so appreciative of her desire to participate in this project at such a late stage of her illness. I'll never forget that when I asked her why she was willing to come talk to a stranger under these circumstances, she just said: 'Oh, well, I trust the process. Write a good book'."

His next project involves a cultural history of the communal residence and alternative education experiment of the era, Rochdale College on Bloor Street. "I am writing a sequel of sorts to the 91亚色ville book. I am working on a book on Rochdale College and what I have termed 'hip separatism' in the 1970s," he says. "While 91亚色ville saw people performing cultural difference right there in the open," he says, "Rochdale remained closed to outsiders and tourists聽and聽represents a certain retreat from the integrationist, even evangelical, politics of '60s-era hip youth."

Despite his fascination with the 1960s, Henderson says that if he could dine with anyone, dead or alive, his choice would be Canadian artist Tom Thomson. "I have some good buddies who died too young. It'd be nice to see one of them again, but how do you choose? So, I'll be a Canadian cultural historian and say dinner over a campfire with Tom Thomson somewhere in Algonquin Park on a star-filled night. But mostly because I really like camping."

91亚色 researchers have zeroed in on a genetic process that may allow ovarian cancer to resist chemotherapy.

Researchers in the University鈥檚 studied a tiny strand of our genetic makeup known as a microRNA, involved in the regulation of gene expression. Cancer occurs when gene regulation goes haywire.

鈥淥varian cancer is a very deadly disease because it鈥檚 hard to detect,鈥 says biology Professor who co-authored the study. By the time it's diagnosed, usually it is in its late stages. And by that point there鈥檚 really no way to treat the disease. Even when the disease is discovered in its early stages, chemotherapy doesn鈥檛 always work,鈥 she says.

Right: Chun Peng

Peng was among a team of researchers that discovered a receptor, ALK7, that induces cell death in epithelial ovarian cancer cells. They have now discerned that microRNA 376c targets this crucial receptor, inhibiting its expression and allowing ovarian cancer cells to thrive.

Our evidence suggests that microRNA 376c is crucial to determining how a patient will respond to a chemotherapeutic agent,鈥 says Peng. 鈥淚t allows cancer cells to survive by targeting the very process that kills them off,鈥 she says.

In examining tumours taken from patients who were non-responsive to chemotherapy, researchers found a higher expression of microRNA 376c and a much lower expression of ALK7.

Peng believes that this research is a step towards being able to make chemotherapy drugs more effective in the treatment of the disease.

鈥淔urther study is needed, but ultimately if we can introduce anti-microRNAs that would lower the level of those microRNAs that make cancer cells resistant to chemotherapeutic drugs, we will be able to make chemotherapy more effective against ovarian cancer,鈥 Peng says.

She urges women to educate themselves about the risk factors and symptoms of the disease. For more information, visit .

Peng is a world expert in the area of ovarian cancer and the molecular basis of complications in pregnancy. Her research on chemo-resistance has also contributed to knowledge and prediction of pre-eclampsia, a pregnancy disorder that is a leading cause of maternal and perinatal complications and death.

The article, 鈥淢icroRNA 376c enhances ovarian cancer cell survival by targeting activin receptor-like kinase 7: implications for chemoresistance鈥, was published in the Journal of Cell Science.The study鈥檚 lead author, Gang Ye, is a research associate in Peng鈥檚 lab. Several trainees in Peng鈥檚 lab, as well as scientists in Toronto鈥檚 Sunnybrook Research Institute and in China also participated in the project.

The research was supported by an operating grant from the (CIHR) and a mid-career award to Peng from the Ontario Women鈥檚 Health Council/CIHR. Ye was supported in part by a fellowship from the Toronto Ovarian Cancer Research Network.

Medical publications distributed freely to health professionals often promote drugs that are costly or have potential problems, says a new study warning that such practices could influence which drugs doctors prescribe, wrote :

Unlike medical publications that require paid subscriptions, free journals get most or all of their funding from pharmaceutical advertising.

A group of researchers keen to discover what effect industry ties have on the content of published medical journals conducted a detailed comparison of journals that are free, those that have some pharmaceutical advertising and subscription fees, and those that are subscription-only.

Their findings, published on Monday in the Canadian Medical Association Journal, show that free journals are much more likely than other publications to display ads for new drugs that are more expensive than older, generic versions as well as drugs that are linked to some concerns over effectiveness.

But the researchers also discovered that free journals frequently print editorial content that directly recommends the drugs that are advertised in the journal.

鈥淚t鈥檚 pretty well drug company advertising,鈥 said Joel Lexchin, a professor in the School of Health Policy & Management [Faculty of Health] at 91亚色 in Toronto and one of the study鈥檚 authors. 鈥淭hese journals probably have a role in influencing prescribing behaviour.鈥

Health Canada did not pull a pain drug off the market until US officials made the decision to recall it, a move sparking criticism of the government's ability to act independently to protect the safety of Canadians from potentially dangerous medications, reported :

Health Canada and Paladin Labs Inc. announced a recall Wednesday of Darvon-N, the brand name of dextropropoxyphene, also known as propoxyphene, after new research showed the drug is linked to serious abnormal heart rhythms. The announcement came less than two weeks after the US Food and Drug Administration decided the drug should be removed from the market.

But widespread safety concerns about the drug have actually been around for decades, and prompted Britain and the European Union to ban Darvon-N amid fears it was linked to suicide and accidental overdose.

Joel Lexchin, a professor in 91亚色鈥檚 School of Health Policy & Management, said should have taken an active role with respect to Darvon-N, as well as other drugs. The department's follow-the-leader behaviour exposes major shortcomings and weaknesses in its drug monitoring capabilities, he said.

"This drug should have been off the market 30 years ago," Lexchin said in an interview Thursday. "Unfortunately, it took this long to get it off the market."

Health Canada should beef up its system for monitoring the safety of drugs as well as tracking the number of patients who experience serious side effects, he said.

Lexchin is a co-author of , which calls for sweeping improvements to drug safety in Canada.

Pharmaceutical promotion may cause doctors to prescribe more expensively, less appropriately and more often, according to a new study co-authored by physician and 91亚色 Professor Joel Lexchin.

The findings, published聽Wednesday in the journal, PLoS Medicine, offer a broad look at the relationship between doctors鈥 prescribing habits and their exposure to information provided by drug companies. Researchers analyzed 58 separate studies of this phenomenon from Canada, the United States, Europe and Australia, dating from the 1960s.

Left: Joel Lexchin

鈥淢any doctors claim they aren鈥檛 influenced by the information provided by pharmaceutical companies. Our research clearly shows that they are 鈥 and the influence is negative,鈥 says Lexchin, a professor in the School of Health Policy & Management in 91亚色鈥檚 and an emergency physician in Toronto.

鈥淯nfortunately, patients are the ones getting a raw deal. If doctors are inundated with advertising from brand- name companies, they are more likely to prescribe that brand name, regardless of whether it鈥檚 best for the patient.鈥

All but one of the studies suggested that exposure to promotional information was associated with lower prescribing quality; the one remaining study detected no association. Findings also show that promotional information led to more frequent prescribing; studies dealing with this correlation either showed a spike in prescribing or detected no association. Researchers also established a link between promotion and higher prescribing costs.

Lexchin says Canadian drug companies spend big money on marketing their products to physicians, to the detriment of other priorities such as research and development.

鈥淚n Canada, companies are estimated to be spending anywhere between $2.4 and $4.75 billion annually on promotion, one of the major reasons why spending on brand-name drugs was rising at a rate of just under 10 per cent annually until two years ago,鈥 he says.

A limitation of the research is that most studies were observational in nature, meaning that the majority of physicians who participated were not randomly selected.

The researchers found no evidence that drug companies' promotional efforts improve prescribing behaviour in any way, but, says Lexchin, 鈥渢hat doesn鈥檛 entirely exclude the possibility that prescribing might sometimes be improved.鈥 However, he adds, "As a precaution, we recommend that physicians avoid exposure to the information provided by pharmaceutical companies.鈥

The study, 鈥淚nformation from pharmaceutical companies and the quality, quantity and cost of physicians鈥 prescribing: a systematic review鈥, was led by Geoffrey Spurling,聽a聽professor at the University of Queensland, Brisbane, Australia. To read it, visit the website.

Health Canada鈥檚 drug safety system favours the interests of pharmaceutical companies, according to a report that says the department needs to do more to protect Canadians,

In a paper produced by the , Dr. Joel Lexchin writes that while some drugs will always pose risks for some people, it is Health Canada鈥檚 job to identify as many potential problems as possible before drugs are approved for sale, to monitor them once they are approved, and to communicate any new safety information about them effectively.

The agency has neither abandoned those responsibilities, nor is it embracing them, the report states. 鈥淚f we want to ensure that drugs are prescribed and used as safely as possible, then needs to reorient its priorities,鈥 Lexchin said in an interview. 鈥淭here are things it could be doing right now that it鈥檚 not doing.鈥

Lexchin, an emergency room doctor who teaches in 91亚色鈥檚 School of Health Policy & Management in the Faculty of Health, said there is too much emphasis on getting drugs on the market quickly, and that the financial penalties levied on the department for not meeting time targets 鈥 180 days for reviewing drugs identified as priority drugs and 300 for non-priority drugs 鈥 are problematic. 鈥淲hen you鈥檙e faced with that kind of thing, people are operating under pressure and they may not do as thorough a job as they think they need to,鈥 said Lexchin.

The majority of Health Canada employees do a good job, he said, but it鈥檚 a lack of political will to make the drug regulation system safer and more effective that is at issue.

Canada needs a new system for controlling drug prices that does not depend on whether or not a drug has received a patent, according to an article by 91亚色 Professor Dr. Joel Lexchin.

Drug prices in Canada can be unregulated for years, a period during which companies may overprice the drugs and market them, says Lexchin, a professor in the School of Health Policy & Management in 91亚色鈥檚 and an emergency physician at the Dr. Joel Lexchin, professor in 91亚色's Faculty of Healthin Toronto.

Left: Dr. Joel Lexchin.

His commentary, 鈥溾, appears in the journal Open Medicine. It is based on new research which examined how many drugs in Canada are marketed before they are patented, whose prices are therefore not controlled by the federal Patented Medicine Prices Review Board. He also looked at the time period between marketing and patenting, and any excess revenue generated before those drug prices were regulated.

In total, 42 drugs were marketed between 2000 and 2008 before being patented, and complete data was available for 33 of those.

鈥淪ome of these drugs were potentially being marketed for weeks before they came under the jurisdiction of the review board and had their prices controlled, but some of them may have been marketed for years,鈥 says Lexchin. 鈥淥nly聽three of the 33 drugs were found to be overpriced, but the fact that one of the 33 drugs may have been marketed without price controls for more than seven years is troublesome.鈥

When drugs are finally patented, their prices are reviewed and if a drug is deemed to be overpriced, the review board can order a company to repay any excess revenue to the federal government. The problem is that if companies overprice their drugs, the drugs may not be added to provincial formularies such as the Ontario Drug Benefit Formulary. In Ontario, the government covers most drugs listed on the formulary for people who are eligible, so if a drug is not on the list, the cost will not be covered.

In addition, although excess revenue from the drugs is eventually recovered, it is paid to the federal government, not the provincial governments which fund drugs through their drug benefit schemes, or to private insurers or people who are paying the cost out-of-pocket, says Lexchin.

The best remedy for various problems caused by using patent status to regulate prices is simply to treat all drugs on the market equally and regulate all prices, he concludes.
