Common food preservative may slow, even stop tumor growth

ScienceDaily (Oct. 30, 2012) ? Nisin, a common food preservative, may slow or stop squamous cell head and neck cancers, a University of Michigan study found.

What makes this particularly good news is that the Food and Drug Administration and the World Health Organization approved nisin as safe for human consumption decades ago, says Yvonne Kapila, the study's principal investigator and professor at the University of Michigan School of Dentistry.

This means that obtaining FDA approval to test nisin's suggested cancer-fighting properties on patients in a clinical setting won't take as long as a new therapy that hasn't been tried yet on people, she says.

Antibacterial agents like nisin alter cell properties in bacteria to render it harmless. However, it's only recently that scientists began looking to antibacterial agents like nisin to see if they altered properties in other types of cells, such as cancer cells or cells in tumors.

Oral cancer is a leading cause of death worldwide, and oral squamous cell carcinoma accounts for more than 90 percent of oral cancers. However, survival rates for oral cancer haven't improved in decades, according to the study.

"The poor five-year survival rates for oral cancer underscore the need to find new therapies for oral cancer," Kapila said. "The use of small antibacterial agents, like nisin, to treat cancer is a new approach that holds great promise. Nisin is a perfect example of this potential because it has been used safely in humans for many years, and now the laboratory studies support its anti-tumor potential."

The U-M study, which looked at the use of antimicrobials to fight cancerous tumors, suggests nisin, in part, slows cell proliferation or causes cell death through the activation of a protein called CHAC1 in cancer cells, a protein known to influence cell death.

The study is the first to show CHAC1's new role in promoting cancer cell death under nisin treatment. The findings also suggest that nisin may work by creating pores in the cancer cell membranes that allow an influx of calcium. It's unclear what role calcium plays in nisin-triggered cell death, but it's well known that calcium is a key regulator in cell death and survival.

Additionally, the findings suggest that nisin slows or stops tumor growth by interrupting the cell cycle in "bad" cells but not the good cells; thus nisin stops cancer cell proliferation but doesn't hurt good cells.

Mich. police seek suspect in 22 roadway shootings

(AP) ? Officers have begun pulling over and questioning drivers in four Michigan counties in the hopes of catching a man suspected of shooting at other motorists nearly two dozen times over the past two weeks, including one driver who was wounded over the weekend.

Officers are searching for anything out of the norm during their traffic stops in Oakland, Livingston, Ingham and Shiawassee counties, where the suspect is believed to have fired on 22 other vehicles since Oct. 16, said Lt. Mike Shaw, of the state police post in Brighton.

Witnesses have described the suspect's vehicle as resembling a dark 1998 Oldsmobile Alero or a 1998 Toyota Camry. Police on Monday stopped the driver of a dark-colored Chevy Cavalier after a woman reported that something hit her car on U.S. 23 near Brighton.

Those initial descriptions may not be correct, Shaw told The Associated Press Tuesday.

"We've had 22 victims that have tried to identify a vehicle traveling at 60 to 70 mph," he said. "We're looking for more suspicious activities that go with four-door vehicles and those darker in color ? somebody that's pulled over on the side of a road or coming out of a wood line on the side of a freeway. Or if you see the same car driving around with no sense of purpose.

"We'd rather check that out and err on the side of caution."

Shaw didn't have any totals on the number of cars stopped, but said drivers "have been more than cooperative."

More than 100 local police, sheriff's deputies, state troopers and federal agents are involved in the investigation, which began with reported shootings in Wixom, about 25 miles northwest of Detroit.

A western Michigan man was shot in the buttocks Saturday while driving to Detroit along Interstate 96 in Livingston County. He is the only person wounded so far, but the suspect is believed to be shooting at people ? not just their vehicles, Oakland County Sheriff Michael Bouchard said Tuesday.

"It's been more of the grace of God than the guy intentionally missing people," Bouchard said. "We've had people who have been missed (by) inches. One bullet was lodged in a driver's seat."

The suspect is believed to be shooting at vehicles approaching from the opposite direction, Shaw said.

Some motorists didn't realize their vehicles had been hit until a quarter-mile or more later.

A task force put together to investigate the shootings has received more than 800 tips, including 200 that came in after the reward money for information that leads to an arrest was increased Monday from $12,000 to $102,000, Bouchard said.

Authorities say it's imperative that they catch the suspect not only to protect lives, but to stop the spread of fear affecting everyday life.

"For Halloween, we are going to do special patrols in each of our subdivisions so kids can have a normal Halloween," said Clarence Goodlein, Wixon's public safety director. "We're not going to be in the business of letting a thug and hoodlum bully us and change the course of our lives."

You Don't Have to Be Crazy To Work Here | According To Hoyt

So, how does one become a writer?? The long-delayed post today ? because I had a routine doctor?s checkup ? gave me time to come back and look at your comments, and we can all agree that a degree in creative writing is about as useful as a meringue hammer.? At least I hope we all agree, because I?m sure of this.

In fact, what little I took in terms of creative writing in school probably hindered my writing commercial fiction.? It?s sort of looking at things the wrong way.? Your Creative Writing professor might have been ecstatic at the bit of symbolism in which you dress a character all in white to symbolize purity, but the reader is probably not even going to register it consciously, and if your character all-in-white proceeds to do nothing much that?s interesting, then well? The reader won?t be happy.

Mostly what the reader wants is to experience emotions.? If along with it you can backload some stuff to make the reader think, and if your reader is a thinking sort of person, bonus.? But mostly the reader wants to experience something and ?emotions? is the common denominator, atop of which you add the peculiar ?cookies? of each genre.? So, say, for romance, you have to have ? romantic stuff and tension between the couple; for SF (depending on subgenre) cool stuff like robots and space exploration; for fantasy everything from LOTR plus some; for urban fantasy shifters and vamps and hot chics (or cute guys) fighting them.? However if all those things don?t contribute to the emotional experience, you got nothing.

While from the critics end? well? they?re looking for symbolism and meaning and wondrous stuff like allusions to other books? yeah.? And most college courses teach you to be critics not writers.

So ? you can?t learn it in college.? What makes a writer a writer?

Well, you don?t have to be crazy to work here, but it helps.

Most of us started out telling ourselves stories.? Or we told younger siblings stories.? (I only had cats younger than I, and they were notoriously averse to standing still while I told them stories.)? Or, when we were older, we told our peers stories (guilty!)

I wrote my first ?novel? at six.? It was ten handwritten pages and Enid Blyton Famous Five Fanfic.? (Hey, one does what one can.)

By highschool I was writing 20k word ?novels? of very, very bad Clifford Simak pastiche.

And that?s part of what makes you a writer.? Like the artists of old who copied the works of the masters, almost all of us started out by writing things in imitation of those authors whose work had moved us the most.

At some point we realize it?s not quite ours, and we start experimenting.? For me that was my twenties, which generated a never end of REALLY BAD experiments, including some that can never be buried DEEP enough.? In fact, my kids are under notice if they find and publish any of them, I?ll come back and haunt them into the next century.

But in the middle of the experiments, my taste, formed by an awful lot of reading, picked this and that that worked, and that other thing that sparkled, and?? And I started to get a clue.

In my early thirties I had the revelation that I was writing for a reader.? Yeah, I know.? I?m slow that way.? Now, I had no idea who ?my reader? was or how he functioned, but I had an idea that I would write for the reader I?d like to attract.

And then it became sort of like playing chess on both sides, and things started to work.? That mind set is absolutely necessary to know when you?re too slow, when you?re too fast, when you?ve skipped something essential?

So ? it?s hard to acquire, though at this point it?s second nature.? (Posting at austen.com and getting comments as I wrote really helped that sense of what the readers were getting or not.)

And there it is.? You become a writer by:

1-????? Copying the masters.

2-????? Learning to go beyond copy

3-????? Reading an awful lot

4-????? Learning to write for readers.

Sounds easy, right?? Right.? And you?re wondering where the part comes where you suffer for your art, aren?t you?

Trust me, there?s suffering enough in there.? Like most simple plans, the difficulty is in the execution.

Now ? go work.

93% The Sessions

All Critics (88) | Top Critics (32) | Fresh (82) | Rotten (6)

Most often with The Sessions the blunt comedy outweighs the drift toward sanctimony.

It sends viewers out of the theater with a heightened sense of the physical and a real feeling for all the things that sex means in human life.

The achievement of this simply told, exceptionally fine film is the clarity with which it portrays the drama of a good soul in an inert body.

Hawkes' performance is the must-see hook of The Sessions, but Hunt gives this funny, touching movie its soul.

Character actor John Hawkes is often cast as a frightening rustic (Winter's Bone, Martha Marcy May Marlene), but he gives a tender and witty performance here as Mark O'Brien.

The joy of The Sessions goes beyond sexual healing. It makes physical intimacy far more a matter of the heart, and you won't be alone wiping an occasional tear.

"The Sessions" introduces us to some harsh truths we may not want to consider, but the outcome is one we cannot fail to understand.

"The Sessions" is a film that reminds us of the fragility of life, and how human beings are capable of a deep emotional bond when it is least expected.

... a story of triumph over disability that takes the form of an uplifting sex comedy rather than a depressing saga of a dying man.

That exceedingly rare combination of sexy, clever and sweet, a winning tale of one charming disabled man's quest to get some stank on his hangdown.

The film greatly benefits from Hawkes' tremendous performance. (Full Content Review for Parents also available)

For the entire endeavor to emotionally register, you must buy into the romance that purportedly blossoms between Hawkes and Hunt. I didn't, not for a second.

Hawkes' work here is that good that it carries one away on a wave of emotion that dismisses critical thought. The film around him could have been better but you're unlikely to realize that while you're watching it.

...a perfectly watchable showcase for two undeniably above-average performances.

Uneven and perhaps a little too tidy as it aims to promote one man's extraordinary spirit. It is John Hawkes and Helen Hunt, however, who are most worth seeing.

Practically ignores everything about O'Brien's life except as it relates to his sexual odyssey, turning the life of the man into little more than a curio.

A powerful expression of our common needs, fears, and consolations.

For better and for worse, The Sessions has 'crowd-pleaser' written all over it.

Artist will stare 'fitness for work' fears in the face with 'bed life ...

An award-winning disabled artist is to spend three days in bed in front of an audience, in an attempt to portray the contradictions of her impairment, and the government?s ?miserable, terrifying, punishing? fitness for work assessment regime.

The writer-director-activist Liz Crow is forced to spend much of her life in bed because of her impairment, but has always managed to keep that part of herself hidden from view.

?I have developed this incredibly stark way of living,? she says, ?and what other people see of me in public spaces is not how I am for most of my life. Even the people close to me don?t really know me at the most extreme.?

In?Bedding In?, she will make her ?twilight existence visible?, exposing the part of her life she spends in bed to public scrutiny, and for the first time ?parading? this private self in public.

The piece, part of this year?s SPILL Festival of Performance, in Ipswich, is Crow?s response to the government?s harsh benefits reassessment programme.

But rather than lying low for fear of being penalised by the Department for Work and Pensions, she has decided to ?stare that fear in the face?.

She is one of the hundreds of thousands of long-time incapacity benefit claimants who have been tested through the government?s reassessment programme, and subjected to the infamous work capability assessment, carried out by the government?s contractor Atos Healthcare.

Even though Crow has used a wheelchair for 26 years, Atos decided that she had no difficulty walking. She was placed in the work-related activity group (WRAG), for those thought able to move towards paid work.

But she knows she cannot make herself available for work, and so ? unless she wins her appeal ? she has resigned herself to having her benefits taken away because of the inevitable failure to co-operate with the regime.

?The consequences are that I may have no income coming in and don?t know how as a single parent I will care for my child, let alone my home, etc.?

Less than two weeks after her performance ends, she will need to parade her private self again, when she appeals to a tribunal against the decision to place her in the WRAG.

Crow is clear that she wants Bedding In to be about the complexity of her impairment, and not its ?tragedy?.

?I live a pretty good life with the complicated set of circumstances that I have got,? she says, ?but if I step out of my bed then it is not seen as complexity or contradiction, and in the current benefits system it means you fall through the gaps.?

Each day during the performance at Ipswich Art School Gallery, members of the public will gather around her bed to discuss the work, and its politics. The hope is that Crow will take the ?data? from these conversations and use them to further develop the piece.

?It is a political statement,? she says of the performance, ?but it is also trying to make visible this kind of internal wrestling that goes on for a lot of us with the benefits stuff.

?Since I got personal assistants 15 years ago I have managed to find a kind of fragile security in my life. I have rarely earned but I have, I hope, contributed.

?Now the benefits thing has kicked in it has all gone. Suddenly I don?t feel I have any security left whatsoever.?

Even if she wins her appeal, she faces the likely prospect of being reassessed again in another year or so, and then again, and again.

?The idea that this is life now: that is just dire. There are hundreds of thousands of us going through this assessment. There is some small comfort that there are a lot of us in it together but it is not much comfort because of the toll it takes.

?I have this tiny amount of time when I am well enough to do stuff and I am looking at that time being taken away.

?It has been really hard to create the life I have got, a reasonable life, and this big system comes along with these politicians who are so extraordinarily removed from a life like mine and they demolish what I have built up.?

The whole process feels, she says, like ?punishment?, not assessment, ?an endless round of justifying myself and fighting for a grain of security?.

?There are layers and layers of why it is so hard. One of the things is that if you fall through the gaps, for the press it is evidence that you are a scrounger and a fraudster.?

She is among the many disabled activists who believe that this cruel assessment process ? and the callous and incompetent way it is carried out by Atos ? are responsible for the premature deaths of hundreds, if not thousands, of disabled people.

Even if these deaths are not caused by the process, she says, ?actually they died among all this shit, their last few months were so miserable and so frightening, and I think that?s unforgivable. To condemn people to a really miserable last few months is diabolical.?

Crow feels there is an affinity between her performance and the direct action protest carried out by members of Disabled People Against Cuts (DPAC) at Marble Arch in central London last weekend.

One of the reasons she is so impressed with DPAC?s campaigning work, she says, is that ?they have created an incredible visible presence but have found ways for all sorts of people to contribute?, particularly through social media.

She also sees links with her most recent piece of work, Resistance, an award-winning video installation about the Aktion-T4 programme, which led to the targeted killing of as many as 200,000 disabled people, and possibly many more, in Nazi Germany.

She began working on Resistance in 2008, and started thinking about its themes several years earlier, and felt even then that there were contemporary ?connections?.

?Those contemporary connections have just got stronger and stronger,? she says. ?I am appalled to feel that we are under greater threat now than we have been in all the years I have been involved in activism.?

She points to newspaper reports of alleged disability benefit fraud and the use of language like ?shirkers?, ?scroungers? and ?fakers? to describe disabled people. This kind of propaganda, she says, is ?eerily familiar? from descriptions of pre-Holocaust Germany.

The ?specifics? of what is happening now are not the same as in Nazi Germany, she adds, but ?the values beneath it are, this idea that we are somehow dispensable, more dispensable than others?.

She also points to the Paralympics, which she says ?makes the scrounger-fraudster rhetoric stronger, and leads to a backlash?.

There are even similarities between the Paralympic classification system, and the benefits assessment system. Both suit those who have a ?bio-mechanical, quantifiable impairment?, rather than less clear and easily-determined impairments.

Would-be Paralympians with ?nebulous impairments? fall through the gaps, she says, just as she and many tens of thousands of other disabled people have fallen through the yawning gaps in the benefits system.

Bedding In is part of?Disability Arts Online?s??Diverse Perspectives project, which is funded by Arts Council England, and is commissioning eight disabled artists to make new artwork that ?sparks conversations and debate about the creative case for diversity?.

Bedding In?takes place at the Ipswich Art School Gallery from 1-3 November, from 11am to 6pm, as part of the SPILL Festival of Performance in Ipswich.
