Espoir montréalais d’un vaccin contre le cancer

Une équipe de l’Institut de recherche en immunologie et en cancérologie de l’Université de Montréal espère bien pouvoir, d’ici trois ans, tester sur des humains un vaccin thérapeutique pouvant traiter le cancer.

L’équipe du docteur Claude Perreault est à l’origine de ce projet qui pourrait être une première mondiale.

« Depuis une dizaine d’années, il y a de plus en plus de preuves que le système immunitaire, notre système immunitaire, peut éliminer des cellules cancéreuses », explique le chercheur. « Mais la grande question que l’on se pose : les cellules immunitaires, que reconnaissent-elles qui leur permet d’éliminer les cellules cancéreuses? »

C’est cet élément mystère que tentent de découvrir plusieurs équipes de recherche partout sur la planète. Celle du docteur Perreault a toutefois cherché là où personne n’avait regardé auparavant : une portion de l’ADN des cellules cancéreuses que l’on croyait inutile, « l’ADN poubelle ».

« Ça a nécessité de trouver de nouvelles méthodes pour étudier toutes les protéines de tout l’ADN. Et pour cela, j’ai bénéficié de la collaboration de mes collègues », raconte le chercheur.

Le rôle des antigènes

Les chercheurs de Montréal ont ainsi découvert ce qu’ils appellent des antigènes, des éléments capables de stimuler le système immunitaire pour qu’il s’attaque à différents types de cancer.

« Non seulement ces antigènes cancéreux étaient capables de stimuler le système immunitaire, mais la réponse était suffisamment forte pour faire régresser la tumeur », explique le docteur Perreault.

L’équipe souhaite donc procéder d’ici trois ans à une étude clinique au cours de laquelle elle pourra tester des vaccins sur des patients atteints de cancer autrement incurable.

Quand je dis vaccin, je veux dire un vaccin thérapeutique : un vaccin pour traiter un cancer existant.

Le docteur Claude Perreault

Entre-temps, l’équipe de recherche doit dresser un répertoire des antigènes pour chaque type de cancer.

« Il n’y en a aucun qui nous semble théoriquement intraitable », avance avec confiance le Dr Perreault.

John Summers: How Ottawa lawyer mocked motherhood and society, reveals new book

Editor

Published

An Ottawa based lawyer from a leading law firm has been entangled in a web of controversy due to his action, which many have described has shocking and inhumane.

Despite claiming to uphold justice, human rights and societal values, John Summers, a lawyer at Bell Baker LLP, is a clear-cut example of just how broken the legal system in Canada is. It appears that Summers and his firm for years now have been exploiting a disturbed senior citizens  with chronic health conditions in his continuous abuse of his wife, for financial gains.

Summers has consistently stood in the way of justice by fabricating numerous lies. Resorting to lies in an attempt to hinder justice is an action that is heavily frowned upon by ethical legal practitioners. But Dezrin continued to suffer domestic abuse due to Summers’ action which had preventing her son, Raymond from seeing his own mother.

Summers’ actions since February 2016 has now resulted in the reported premature death of Dezrin Carby-Samuels who had been an RN who was selflessly dedicated to serving both her family and every community that she had lived.

Raymond and his mother, Dezrin, had sought the intervention of the law courts as a last resort in their quest for justice after Dezrin has been consistently abused by her husband, Horace and her daughter, Marcella. Rather than getting the fair hearing and justice that they expected, they received the direct opposite due to Summers apparently employing every dirty trick in the book. He has resorted to lies and illicit collaboration with judges of him alma mata just to inhibit every effort being made by Dezrin and her son.

In a book titled John Summers: The Untold Story of Corruption, Systemic Racism and Evil at Bell Baker LLP, author Peter Tremblay takes readers on a shocking journey into John Summers’ tactics which lacked ethical properiety and human decency.

Summers is proof that the ethical practices associated with the legal profession is quickly fading and it is a course for concern. In the case against Horace, Summers produced an apparent fraudulent affidavit which claimed that Raymond suffers from a mental condition—an entirely false claim. Lawyers like Summers are willing to go any length in an attempt to hinder justice, even if it leads to the destruction of lives and properties.

Summers falsely claimed that his client, Horace couldn’t file a defence for himself because he was unaware of the adopted court proceedings. However, in the early 1900s, Horace was the same one who showed so much confidence in his legal capabilities that he decided not to hire a legal counsel but represent himself during a lawsuit between his union and the Canadian Government. This act is contradictory to Summers’ claim of his poor legal understanding.

As humans, some certain moral ethics and values set us apart from other living things and one of them is showing respect for elders. Lawyers are respected in the society due to their pledge to always ensure justice prevails but Summers’ apparent greed and love for money have made him violate the human rights of an ailing mother and her son.

Peter Tremblay’s book uncovers untold stories of a corrupt system that accommodates abuse in the most inhumane form.  In Canada’s legal system, empathy and compassion were thrown out the door in exchange for money and an unknown demomic agenda. It begs the question: How then are aggrieved citizens supposed to trust a legal system for justice when a lawyer can tell unending lies against a senior citizen without any consequences or accountability?

The Law Society of Upper Canada which is supposed to regulate the legal profession in Ontario is a complete joke run by similarly corrupt lawyers who ignore the misdeeds of their colleagues.

Summers’ actions have led to Dezrin being unable to do anything since she lost her ability to walk, talk or even write due to abuse and ultimately her premature death.

Her inability to receive help from even her own son due to Summers’ fraudulent activities resulted in the destruction of Dezrin Carby-Samuels and for that reason Summers should be barred from the further practice of law anywhere in Canada.

In my view, Summers is an abomination to the legal profession and Peter Tremblay’s book documents the activities of John Summers since 2016 against three judges who where not from Summers’ alma mata and who sought justice for Dezrin and her son.

Since 2016, Dezrin had sought obtain freedom from forcible confinement imposed by her abusive husband but was unsuccessful, due to the interference Summers who refused to divulge who was in fact paying him reportedly $300/hr to frustrate justice.

Reports from credible sources allege that Dezrin passed away sometime last year due to Summers’ evil practices and this report has cast a dark cloud over the future of the legal system in Canada which had been ignoring the plight of other black Canadians.

City staff propose ‘gold belt’ to hem in future Ottawa development

The City of Ottawa is about to have a second marathon debate about where to allow future suburbs to be built, and this time staff propose hemming in development by creating what’s being dubbed the “gold belt.”

Eight months after city council decided to expand the urban boundary by 1,281 hectares to help house a growing population, senior city planners have released the map of which properties should be developed — and which property owners stand to see values soar if their lands are rezoned. 

They include areas north of Kanata on March Road, near the future Bowesville O-Train station in the south end, and at the southern edge of Orléans.

Scoring rural properties on such things as how close they are to transit and how costly it would be to build pipes and roads proved a challenge over the past several months, however.

“The easy land has been gobbled up in years past, in previous boundary expansions,” said Coun. Scott Moffatt, who belongs to a group of councillors that meets about the new official plan. “So now we’re looking at those leftover pieces and where we can [grow], knowing council was clear we would not be touching agricultural lands.”

270 hectares short of goal

Staff struggled to come up with all 1,281 hectares council approved adding in May 2020 because they had too many issues with “sub-optimal” lands.

Instead, they recommended converting 1,011 hectares of rural land to urban for now to meet provincial requirements, and then spending the next five years studying three options for making up the 270-hectare shortfall.

That opens the door to creating an entirely new suburb. 

For instance, one option involves a huge parcel near the Amazon warehouse southeast of the city where the Algonquins of Ontario envision a community of 35,000 to 45,000 people called Tewin, which they would build with developers Taggart.

How an Ottawa woman built a majestic snow dragon in her front yard

OTTAWA — You may sometimes feel winter drag on, but one Ottawa woman is not letting that dim her creativity.

Dr. Mary Naciuk is family doctor and rural emergency room physician. She spent some of her free time this weekend building a majestic snow dragon in front of her south Ottawa home.

“It’s just fun to get outside and do something creative,” she told CTV News on Sunday.

There was plenty of snow to use, after Ottawa saw a record 21 cm of snow on Saturday.

She said that after her husband cleared the driveway, the pile of snow left behind lent itself to being turned into a magnificent dragon, but it takes more than just the right kind of snow to make a sculpture like this.

Naciuk tells CTV News a shovel, a butter knife, a spoon and even a blowtorch were used to give the dragon its sharp edges and defined scales.

“Anything pointy with a small detail is really hard to do with just your fingers or the butter knife and spoon I was using, so (the blowtorch) just makes a fine point,” she said.

Her son tweeted about it on Saturday and Naciuk says many people have stopped to take a look.

“A lot of people stop on their way to the ice rink and have a look and take pictures. It’s kind of fun,” she said.

It was a welcome relief to spend some time working on something creative outdoors, Naciuk said.

“Get outside, get some exercise, clear your mind, do something that is not COVID for a few hours. It obeys all the rules. It was great,” she said, adding that the dragon took her about five hours to build.

She’s been on the front lines of the COVID-19 pandemic for months. 

“It’s been a steep learning curve. It’s been exhausting,” she said. “A lot of the time is learning how to deliver care to people and maintain all the precautions that we need to. That’s been hard. A lot of people are not able to work from time to time, so we fill a lot of extra shifts. It’s been a lot more hours of work than it used to be, that’s for sure.”

Naciuk returns to work on Monday after a weekend of respite but says if the conditions are right—a nice mild day, a good snowfall, and some free time—another sculpture may well appear.
