I had to tell someone I love last night that lemon juice will not cure his cancer. FUCK antiscientific rumours and false hope. They just distract from the best possible medical healthcare and the reality of the situation a person faces. Hundreds of thousands of people around the world are dedicating their lives, wholeheartedly, to a cure. They publish what they discover in books that anyone can read. When they find something that helps, we all know about it, including front line doctors. There is no evil conspiracy to hide the cure, it’s not hidden a test-tube somewhere in a vault. I wish it was, because it wouldn’t take long for someone else to replicate the result anyway. Next time you see some FUCKING BULLSHIT on the Internet, don’t hesitate to stomp it out.
McGill and Université de Montréal researchers revealed yesterday that autism-like behaviors can be rectified in adult mice with compounds inhibiting protein synthesis, or with gene-therapy targeting neuroligins (a membrane protein that regulates synapse formation between neurons.) Their study is published in the journal Nature.
“The autistic behaviours in mice were prevented by selectively reducing the synthesis of one type of neuroligin and reversing the changes in synaptic excitation in cells,” explained Prof. Jean-Claude Lacaille at the University of Montreal’s Groupe de Recherche sur le Système Nerveux Central and Department of Physiology. “In short, we manipulated mechanisms in brain cells and observed how they influence the behaviour of the animal.” The researchers were also able to reverse changes in inhibition and augment autistic behaviors by manipulating a second neuroligin. “The fact that the balance can be affected suggests that there could be a potential for pharmacological intervention by targeting these mechanisms.”
“Since the discovery of neuroligin mutations in individuals with ASD in 2003, the precise molecular mechanisms implicated remain unknown,” said Christos Gkogkas, a postdoctoral fellow at McGill and lead author. “Our work is the first to link translational control of neuroligins with altered synaptic function and autism-like behaviors in mice. The key is that we achieved reversal of ASD-like symptoms in adult mice. Firstly, we used compounds, which were previously developed for cancer treatment, to reduce protein synthesis. Secondly, we used non-replicating viruses as vehicles to put a break on exaggerated synthesis of neuroligins.”
Autism spectrum disorders (ASD) encompass a wide array of neurodevelopmental diseases that affect three areas of behaviour: social interactions, communication and repetitive interests or behaviors. According to the U.S.-based Centers for Disease Control and Prevention, 1 in 88 children suffer from ASD, and the disorder is reported to occur in all racial, ethnic, and socioeconomic groups. ASDs are almost five times more common among boys (1 in 54) than among girls (1 in 252).

A five year study conducted with thousands of local teenagers by University of Montreal researchers reveals that those who used speed (meth/ampthetamine) or ecstasy (MDMA) at fifteen or sixteen years of age were significantly more likely to suffer elevated depressive symptoms the following year. “Our findings are consistent with other human and animal studies that suggest long-term negative influences of synthetic drug use,” said co-author Frédéric N. Brière of the School Environment Research Group at the University of Montreal. “Our results reveal that recreational MDMA and meth/amphetamine use places typically developing secondary school students at greater risk of experiencing depressive symptoms.” Ecstasy and speed-using grade ten students were respectively 1.7 and 1.6 times more likely to be depressed by the time they reached grade eleven.
The researchers worked with data provided by 3,880 students enrolled at schools in disadvantaged areas of Quebec. The participants were asked a series of questions that covered their drug use – what they had used in the past year or ever in their life – and their home life. Depressive symptoms were established by using a standard epidemiological evaluation tool. 310 respondents reported using MDMA (8%) and 451 used meth/amphetamines (11.6%). 584 of all respondents were identified as having elevated depressive symptoms (15.1%). The range of questions that the researchers asked enabled them to adjust their statistics to take into account other factors likely to affect the psychological state of the student, such as whether there was any conflict between the parents and the participant. “This study takes into account many more influencing factors than other research that has been undertaken regarding the association between drugs and depression in teenagers,” Brière said. “However, it does have its limitations, in particular the fact that we cannot entirely rule out the effects of drug combinations and that we do not know the exact contents of MDMA and meth/amphetamine pills.”
The study’s authors would like to do further research into how drug combinations affect a person’s likelihood to suffer depression and they are keen to learn more about the differences between adults and adolescents in this area. “Our study has important public health implications for adolescent populations,” said Jean-Sébastien Fallu, a professor at the University of Montreal and study co-author. “Our results reinforce the body of evidence in this field and suggest that adolescents should be informed of the potential risks associated with MDMA and meth/amphetamine use.”

Pagani published “Prospective associations between meth/amphetamine (speed) and MDMA (ecstasy) use and depressive symptoms in secondary school students” in the Journal of Epidemiology & Community Health on April 18, 2012. The study received funding from Fonds Québécois de Recherche sur la Santé et la Société (FQRSC, 2007-NP-112947).

These people are getting stock-photo freaky on oxytocin.
Oxytocin is widely known as the “love hormone” released during birth and breastfeeding to bond a mother and child, but it’s released other times, too. Oxytocin supposedly overflows us with positive feelings about one another.
Or does it?
The truth will be revealed by Dr. Jennifer A. Bartz (Psychology, McGill) at McGill’s Redpath Museum on February 10 at 5pm, as part of its ongoing “Freaky Friday” series. Her presentation will be followed by the film The Notebook

The Quebec Ministry of Justice and UQÀM (University of Quebec at Montreal) announced North America’s first ever chair for research into homophobia today. The research will be directed by Line Chamberland, a sexologist who published a hard hitting yet constructive and pragmatic report into homophobia in provincial schools last year. You can find the report here, in French only.
The fact that the Ministry of Justice is so heavily involved speaks volumes about the Government of Quebec’s investment in the chair and the intended outcomes: researchers will be looking not just at the ways gays and lesbians are discriminated against, but they will also be evaluating how effective anti-homophobia programmes run by schools, employers and the health system really are. Researchers are also looking to work closely with partners to put their recommendations into practise. It all adds up to Quebec taking this issue seriously and wanting to make concrete progress, both here and beyond. Today’s announcement was made in the presence of the Premier of Quebec, the province’s Attorney General (Procureur général), and the university’s rector.

A study published today in The Lancet by Dr. Fred Saad of the University of Montreal and Dr. Mathew R. Smith of the Massachusetts General Hospital Cancer Center reveals that the drug denosumab inhibits the bone metastasis of prostate cancer. The researchers worked with 1432 men suffering from a castration resistant prostate cancer and found that the bone-metastasis-free survival of those receiving the drug increasing by a median of 4·2 months compared to the control group. Overall survival did not differ between groups. Bone metastases are a major cause of morbidity and mortality in men with prostate cancer.
Dr. Fred Saad is available to speak with the media about this study and prostate cancer generally. To set up an interview or to obtain a copy of the study, please contact William Raillant-Clark, University of Montreal, at 514-343-7593 or firstname.lastname@example.org
