The researchers published their findings, "Cannabidiol Prevents the Development of Cold and Mechanical Allodynia in Paclitaxel-Treated Female C57Bl6 Mice," in the journal Anesthesia and Analgesia.
The researchers developed animal models and tested the ability of the compound cannabidiol, which is the second most abundant chemical found in the marijuana plant, to relieve chemo-induced neuropathic pain, said Sara Jane Ward, research assistant professor of pharmaceutical sciences in Temple's School of Pharmacy and the study's lead author.
"We found that cannabidiol completely prevented the onset of the neuropathic, or nerve pain caused by the chemo drug Paclitaxel, which is used to treat breast cancer," said Ward, who is also a research associate professor in Temple's Center for Substance Abuse Research.
Ward said that one of cannabidiol's major benefits is that, unlike other chemicals found in marijuana such as THC, it does not produce psycho-active effects such as euphoria, increased appetite or cognitive deficits. "Cannabidiol has the therapeutic qualities of marijuana but not the side effects," she said.
Ward's research has long focused on systems in the brain that are impacted by marijuana and whether those systems could be targeted in the treatment of various disorders. "Marijuana binds to the cannabinoid receptors in the body and researchers have long been interested in whether there is therapeutic potential for targeting this receptor system," she said.
Ward became interested in this current study after attending a conference in which she learned about a pain state that is induced by chemo-therapeutic agents, especially those used to treat breast cancer, which can produce really debilitating neuropathic pain.
Cannabidiol has also demonstrated the ability to decrease tumor activity in animal models, said Ward, which could make it an effective therapeutic for breast cancer, especially if you "combined it with a chemo agent like Paclitaxel, which we already know works well."According to Ward, there are currently about 10 clinical trials underway in the United States for cannabidiol on a range of different disorders, including cannabis dependence, eating disorders and schizophrenia. Because of this, she believes it will be easier to establish a clinical trial for cannabidiol as a
therapeutic against neuropathic pain associated with chemo drugs.
In addition to Ward, Temple researchers involved in the study included Michael David Ramirez, Harshini Neelakantan and Ellen Ann Walker. The study was supported by grants from the National Institutes of Health and the Peter F. McManus Charitable Trust.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
