• Brock lecture to explore how discrimination affects mental health

  Friday, October 19, 2018 | By Brock University

  MEDIA RELEASE: 19 October 2018 – R00184

  A new lecture series at Brock University aims to explore how racism and xenophobia can affect access to health care.

  As part of Brock’s new Yosif Al-Hasnawi Memorial Lecture Series, guest Uppala Chandrasekera, Director of Public Policy for the Canadian Mental Health Association Ontario, will deliver a presentation on Monday, Oct. 22.

  The lecture series focuses on promoting racial justice in health care and is named after the first-year Medical Sciences student who was shot and killed in Hamilton in December 2017 while trying to protect an older man from two aggressors.

  “Yosif had dreams of becoming a doctor and hoped to one day make a difference in the world,” says Department of Health Sciences Chair Ana Sanchez. “The Department of Health Sciences and the Centre for Women’s and Gender Studies have joined together to host these lectures and are committed to his memory and his dream.”

  This inaugural lecture will explore the causes of discrimination and its impact on mental health, and identify opportunities and resources for addressing discrimination at an individual, organizational and systemic level.

  “In this series, we want to bring forth the importance of exploring how racism and xenophobia can affect access to health care — and the importance of challenging those barriers to ensure that everyone has access to something that all Canadians consider a basic right,” explains Margot Francis, Associate Professor of Women’s and Gender Studies and Sociology.

  The event’s opening and closing remarks will be provided by Brock President Gervan Fearon and Brock Director, Human Rights and Equity Leela MadhavaRau, respectively.

  Held from 11 a.m. to 1 p.m. in South Block 203, the lecture is free and open to the Brock community as well as the general public.

  The event is co-sponsored by the President’s Advisory Committee on Human Rights, Equity and Decolonization; Faculty of Applied Health Sciences; Faculty of Social Sciences; Centre for Women’s and Gender Studies; Brock University Human Rights and Equity Office; Tecumseh Centre for Indigenous Research and Education; and Brock University Students’ Union.

• Lavender research leads to scientific first

  Wednesday, October 17, 2018 | By Brock University

  MEDIA RELEASE: 17 October 2018 – R00183

  It started off as a hobby and ended up becoming a scientific first.

  The lavender garden that Brock University Biological Sciences Associate Professor Ping Liang cultivated at his home inspired him to delve deep into the inner workings of the aromatic herb, whose essential oil is widely used in health and beauty products.

  Liang, a geneticist, bioinformatist and Canada Research Chair, assembled a research team that included Brock PhD student Radesh Malli and University of British Columbia biologist Soheil Mahmoud, an expert on lavender biology and biochemistry.

  After four years of meticulous study, the researchers recently announced that they were the first to sequence the genome of the lavender plant.

  “Knowing the lavender’s genome will help the breeder make the plants more profuse,” said Liang. “We know what genes to manipulate to get what we want, which is a higher yield of essential oils from the plant.”

  A genome — the entire genetic material of an organism — contains all the information needed to build and maintain that organism. Genomes are stored in long strands of DNA, while genes are housed in short DNA strands.

  DNA is made up four letters — A, G, C and T — which repeat themselves in strings of different combinations. Sequencing involves determining the order of those letters. Liang and his team collected the lavender plant’s DNA and sent it off to a commercial DNA sequencing centre, which broke the DNA into tiny fragments, identified the letters in each fragment and transmitted the data back to the team.

  Malli’s job was to re-assemble the strings of 870 million letters to form a draft genome sequence. Sequences are continually updated as scientists learn more.

  “It’s like putting together a jigsaw puzzle: each copy is not complete, you only get a very small portion of it,” said Malli. “You start on the small pieces and eventually you recover the entire original picture.”

  Once an organism’s genome has been sequenced, scientists can then translate it to discover more about the organism.

  “The next part is to figure out what’s inside the genome; that’s called genome annotation,” said Liang. “We find out what the genes are, what they do, where the genes are and what their relationship is to the property of the plant.”

  He said results so far have been highly encouraging.

  “We can see why this plant is generating so much essential oil because it has many copies of genes unique to essential oil-producing plants,” said Liang.

  The sequenced lavender genome will help breeders create cultivars that meet specific requirements, such as the levels of certain chemicals that determine scent quality and quantity, through the selection of particular genetic markers.

  Interested industries can use the genome sequences to test out different cultivars to choose the ones that lead to the most efficient production of lavender essential oils.

  The lavender plant is a member of the mint family. In addition to having what is widely considered a pleasant aroma, research has shown it has a host of medicinal benefits, such as helping to heal minor cuts, insect bites, fungus infections and anxiety. Earlier research by Mahmoud explored lavender’s ability to be a natural pesticide.

  The research team’s latest findings are reported in the Sept. 29 issue of the journal Planta.

  Research funders include the Natural Sciences and Engineering Research Council of Canada, Canada Research Chair Program and the Investment Agriculture Foundation of B.C., and was made possible by Compute Canada/SHARCNET high performance computing facilities.
