Inhibitory effect of some natural and semisynthetic phenolic lipids upon acetylcholinesterase activity.

Food chemistry

Stasiuk M, Bartosiewicz D, Kozubek A.
PMID: 26065763
Food Chem. 2008 Jun 01;108(3):996-1001. doi: 10.1016/j.foodchem.2007.12.011. Epub 2007 Dec 14.

The effect of phenolic lipids isolated from rye grains and cashew nut shell liquid (CNSL) from Anacardium occidentale and their semisynthetic derivatives on erythrocyte ghost's acetylcholinesterase activity was studied. It has been shown that all tested compounds decreased the...

PMID: 33562167
Animals (Basel). 2021 Feb 06;11(2). doi: 10.3390/ani11020424.

Our study aimed to verify the hypothesis of the existence of a programming effect of parental obesity on the growth, development and mineralization of the skeletal system in female and male rat offspring on the day of weaning. The...

Poster - Thur Eve - 28: Optimization of a prostate cancer IGRT protocol.

Medical physics

Dona O, Diamond K, Ostapiak O, Wierzbicki M.
PMID: 28516684
Med Phys. 2012 Jul;39(7):4629-4630. doi: 10.1118/1.4740136.

Our image-guided radiation therapy (IGRT) protocol for post-prostatectomy patients involves acquiring a kV cone beam computed tomography (CBCT) dataset at each fraction and shifting the treatment couch to align the surgical clips. This IGRT strategy requires significant resources, and...

Poster - Thurs Eve-36: Use of multileaf collimator as a replacement of physical missing tissue compensator.

Medical physics

Liu Z, Ostapiak O, Farrell T, Chow T.
PMID: 28512815
Med Phys. 2008 Jul;35(7):3408. doi: 10.1118/1.2965955.

Missing tissue compensators are used to improve dose uniformity for some patients undergoing radiation therapy. Currently, our practice is to machine compensators out of lead alloy plate. Replacing this physical filter with a segmented multileaf collimator (MLC) delivery sequence...

The Durability of an Organic-Inorganic Sol-Gel Interlayer in Al-GFRP-CFRP Laminates in a Saline Environment.

Materials (Basel, Switzerland)

Surowska B, Ostapiuk M, Jakubczak P, Droździel M.
PMID: 31349545
Materials (Basel). 2019 Jul 25;12(15). doi: 10.3390/ma12152362.

The aim of the study was to assess the selected properties of a hybrid organic-inorganic silane sol-gel coating (HSG) used in hybrid fiber metal laminates (FML) in a corrosion environment. The HSG coating on the aluminum alloy was produced...

Kynurenic acid in neurodegenerative disorders-unique neuroprotection or double-edged sword?.

CNS neuroscience & therapeutics

Ostapiuk A, Urbanska EM.
PMID: 34862742
CNS Neurosci Ther. 2022 Jan;28(1):19-35. doi: 10.1111/cns.13768. Epub 2021 Dec 03.

AIMS: The family of kynurenine pathway (KP) metabolites includes compounds produced along two arms of the path and acting in clearly opposite ways. The equilibrium between neurotoxic kynurenines, such as 3-hydroxykynurenine (3-HK) or quinolinic acid (QUIN), and neuroprotective kynurenic...

What residents know about health care reform and what we should teach them.

Journal of graduate medical education

Roberts JL, Ostapchuk M, Miller KH, Ziegler CH.
PMID: 22655136
J Grad Med Educ. 2011 Jun;3(2):155-61. doi: 10.4300/JGME-D-10-00122.1.

PURPOSE: We surveyed residents and fellows at the University of Louisville School of Medicine (N  =  600) to (1) explore their perceptions and knowledge of issues related to health care business and health care reforms, and (2) seek their...

Poster - Thurs Eve-34: Extended CT-range in RT planning of pelvic cancer treatment in presence of hip replacements.

Medical physics

Popovic M, Ostapiak O, Chow T.
PMID: 28512835
Med Phys. 2008 Jul;35(7):3407. doi: 10.1118/1.2965953.

Extended CT range in conventional CT scanners has a potential to allow for a more conformal treatment of patients with hip prosthesis. Its use may limit inaccuracies in electron density maps that are observed due to severe artifacts in...

Poster - Thurs Eve-26: Influence of MLC leaf edge and tongue and groove effect on IMRT dose distributions.

Medical physics

Vallejo F, Ostapiak O, Farrell T.
PMID: 28512802
Med Phys. 2008 Jul;35(7):3406. doi: 10.1118/1.2965945.

An important consideration when using multileaf collimators (MLCs) for IMRT delivery is the correct account of leaf edge effects. To study these effects, two maps were constructed from a clinical beam's step and shoot delivery sequence: a time-weighted leaf...
