Golovachev N, Siebold L, Sutton R, Ghavim S, Harris N, Bartnik-Olson B
J Neuroinflammation . 2024 Nov; 21(1):294. PMID: 39538295
Background: Research on traumatic brain injury (TBI) highlights the significance of counteracting its metabolic impact via exogenous fuels to support metabolism and diminish cellular damage. While ethyl pyruvate (EP) treatment...

Dennis E, Keleher F, Bartnik-Olson B
Adv Neurobiol . 2024 Oct; 42:33-84. PMID: 39432037
Neuroimaging plays an important role in assessing the consequences of TBI across the postinjury period. While identifying alterations to the brain is important, associating those changes to functional, cognitive, and...

Hermosura J, Lohman 3rd E, Bartnik-Olson B, Venezia J, Daher N
PLoS One . 2024 May; 19(5):e0298257. PMID: 38771839
Objectives: The main purpose of this research study was to compare mean modified straight-leg raise test (mSLR) and hamstring muscle length (HL) between chronic non-specific low back pain (LBP) and...

Zaidi M, Ma J, Thomas B, Pena S, Harrison C, Chen J, et al.
Magn Reson Med . 2024 Jan; 91(5):1822-1833. PMID: 38265104
Purpose: Pyruvate, produced from either glucose, glycogen, or lactate, is the dominant precursor of cerebral oxidative metabolism. Pyruvate dehydrogenase (PDH) flux is a direct measure of cerebral mitochondrial function and...

Keleher F, Lindsey H, Kerestes R, Amiri H, Asarnow R, Babikian T, et al.
JAMA Netw Open . 2023 Nov; 6(11):e2343410. PMID: 37966838
Importance: Traumatic brain injury (TBI) is known to cause widespread neural disruption in the cerebrum. However, less is known about the association of TBI with cerebellar structure and how such...

Doose A, Tam F, Hellerhoff I, King J, Boehm I, Gottloeber K, et al.
Transl Psychiatry . 2023 Aug; 13(1):277. PMID: 37573444
The acute state of anorexia nervosa (AN) is associated with widespread reductions in cortical gray matter (GM) thickness and white matter (WM) volume, suspected changes in myelin content and elevated...

Berger L, Holshouser B, Nichols J, Pivonka-Jones J, Ashwal S, Bartnik-Olson B
Metabolites . 2023 Jul; 13(7). PMID: 37512485
The prognostic ability of global white matter and gray matter metabolite ratios following pediatric traumatic brain injury (TBI) and their relationship to 12-month neuropsychological assessments of intelligence quotient (IQ), attention,...
