Congrats twitter-free Mike Mackinley for successful defense of his PhD today. Thanks @JonJoshMemorial @stjosephslondon fdn for many years of supporting Mike's #psychosis research. Thanks @tibbop @DrJKhokhar @PaulFrewen @DrJeanTheberge @peterys_jeon @anderskk3 @roberto_limongi

Publication Late May 2022 from NeuroPIL collaborators @lena_pl and @l_111b with @peterys_jeon showing cortical impoverishment in more prevalent among patients with glutamate excess in early stages and higher residual symptom burden at later stages https://t.co/UTtIiErWMC

Publication from March 2022 by NeuroPIL collaborators @lena_lp and Michael Mackinley, Sabrina Ford and @peterys_Jeon on Central Oxidative Stress and Early Vocational Outcomes in First Episode Psychosis: A 7T MRS Study of Glutathione https://t.co/BywkDFm9tD

New publication from NeuroPIL collaborators @lena_pl and @l_111b, @amsilvaq and @peterys_jeon showing a schizophrenia patient subtype with widespread thinning and higher glutamate concentration in dACC and impaired linguistic functioning https://t.co/05suk7VuZa

Employment/education status after first episode #psychosis, a macroeconomic indicator, varies with central antioxidant #glutathione, a molecular marker. Soon to be online - with @peterys_jeon @DrJeanTheberge

[Biomedical Imaging Research Centre @westernuBIRC]

We are thrilled to announce the appointment of Dr. Jean Théberge, @DrJeanTheberge, Imaging Scientist at @lawsonresearch and MRI physicist at @stjosephslondon @LHSCCanada, as the Director of @westernuBIRC!

Astroglial dysfunction in ACC indexed by reduced 7T MRS myo-inositol resonance is present in early untreated stage of #psychosis
This improves by 6m with improved symptoms, functioning & changes in glutamate

Antioxidant system may provide a means to fractionate #schizophrenia. Key issues relevant to the cortical glutathione system in #psychosis with @DrJeanTheberge @roberto_limongi @peterys_jeon & twitter-free Matt Park, Akira Sawa and Kun Yang https://t.co/e6eNli2l97

[Lena K. Palaniyappan @lena_pl]

We continue to see a link between antioxidant pathway and clinical outcomes in psychosis. Led by twitter-free (but instagram+) Mike Mackinley & Sabrina Ford. In collab. with @peterys_jeon @DrJeanTheberge data from @WesternCFMM 7T

[Claire Park @ClaireKSPark]

It’s been a hot minute since it’s been published in #MedicalPhysics, but our lab JUST realized that @NathanOrlando and Derek Gillies’ paper was selected as Editor’s Choice. 🔥 Please send them (delayed) congratulations!

Check out their article📍https://t.co/9Vfre65KtO @aapmHQ

Congrats @peterys_jeon and twitter-free Mike Mackinley for the Jonathon & Joshua Memorial Graduate Scholarship. Thank you @JonJoshMemorial for many years of supporting #psychosis research at #LdnOnt

It's MRI safety week! With 2021 being the year of MRI safety and the 20th anniversary of the MRI accident in New York that killed a 6 year old child. It's always important to be mindful of the static magnetic field whether it be 3t, 7t or 9.4t

[Lena K. Palaniyappan @lena_pl]

We continue to find an interesting link between #antioxidant #glutathione and functional status - now in a clinical high-risk #psychosis sample. https://t.co/Hs2WbFRkKV @roberto_limongi @peterys_jeon @DrJeanTheberge

[Lena K. Palaniyappan @lena_pl]

Thanks to Matt Park, PGY-4 in @SchulichMedDent psychiatry, our TOPSY data has contributed modestly to this massive effort. Some interesting insights into the relationship bw #schizophrenia / #Alzheimers + surprising sex-diff from the largest assembly of female subjects in scz

[Lena K. Palaniyappan @lena_pl]

We examine 3 mechanistic markers in acute disorganization of first episode #psychosis: #glutamate/ #antioxidant (GSH) ratio and the cingulum.
Reduced cingulum integrity + lower Glu/GSH ratio relate to higher disorganization.

@drkatemerritt @JAMAPsych Congratulations on the awesome work!

[Kate Merritt @drkatemerritt]

(1/) Now this is what I call collaboration! A huge thank you to all 45 studies who contributed MRS glutamate data for this @JAMAPsych paper!

What started out as me pestering people during my PhD has turned into this huge mega-analysis of 1000+ patients https://t.co/w1TtqVjjPR
