The importance of developing care-worker-centered robotic aides in long-term care.

Bioethics

Apostolova I, Lanoix M.
PMID: 34672015
Bioethics. 2022 Feb;36(2):170-177. doi: 10.1111/bioe.12968. Epub 2021 Oct 20.

Recent research points to the fact that new medical technological innovations are just as relevant in the context of long-term care or chronic care as they are in the context of acute care. In the spirit of the Nuffield...

Binding of the antibacterial peptide magainin 2 amide to small and large unilamellar vesicles.

Biophysical chemistry

Wieprecht T, Apostolov O, Seelig J.
PMID: 10961506
Biophys Chem. 2000 Jul 15;85(2):187-98. doi: 10.1016/s0301-4622(00)00120-4.

The thermodynamics of binding of the antibacterial peptide magainin 2 amide (M2a) to negatively charged small (SUVs) and large (LUVs) unilamellar vesicles has been studied with isothermal titration calorimetry (ITC) and CD spectroscopy at 45 degrees C. The binding...

The aim of this study is to explore the potential benefits from the combined use of ultrasound irradiation and catalytic wet peroxide oxidation for the degradation of 4-hydroxybenzoic acid (4-HBA). The target compound degradation was studied under direct and...

Characterization of layered silicate-reinforced blends of thermoplastic starch (TPS) and poly(butylene adipate-co-terephthalate).

Carbohydrate polymers

Lendvai L, Apostolov A, Karger-Kocsis J.
PMID: 28732900
Carbohydr Polym. 2017 Oct 01;173:566-572. doi: 10.1016/j.carbpol.2017.05.100. Epub 2017 Jun 03.

A two-step melt blending procedure was used to produce binary systems composed of thermoplastic starch (TPS) and poly(butylene adipate-co-terephthalate) (PBAT). To improve the properties of the blends, two different layered silicates, viz. bentonite (BT) and organically modified montmorillonite (oMMT)...

Plasma amyloid beta levels are associated with cerebral amyloid and tau deposition.

Alzheimer's & dementia (Amsterdam, Netherlands)

Risacher SL, Fandos N, Romero J, Sherriff I, Pesini P, Saykin AJ, Apostolova LG.
PMID: 31384662
Alzheimers Dement (Amst). 2019 Jul 26;11:510-519. doi: 10.1016/j.dadm.2019.05.007. eCollection 2019 Dec.

INTRODUCTION: We investigated the relationship of plasma amyloid beta (Aβ) with cerebral deposition of Aβ and tau on positron emission tomography (PET).METHODS: Forty-four participants (18 cognitively normal older adults [CN], 10 mild cognitive impairment, 16 Alzheimer's disease [AD]) underwent...

The Evolution in the Management of Gastric Lymphoma.

Gastroenterology research

Hashim D, Apostolova M, Lavotskin S, Goldstein E, Chorost M.
PMID: 27956968
Gastroenterology Res. 2009 Oct;2(5):253-258. doi: 10.4021/gr2009.09.1312. Epub 2009 Sep 20.

The management of gastric lymphoma is a rapidly changing field. The classification and staging of lymphomas have been revised in the past two decades, reflecting diagnostic advances that include the use of immunohistochemical stains and cell-surface markers. Furthermore, the...

A Case of Right Alien Hand Syndrome Coexisting with Right-Sided Tactile Extinction.

Frontiers in human neuroscience

Schaefer M, Denke C, Apostolova I, Heinze HJ, Galazky I.
PMID: 27014036
Front Hum Neurosci. 2016 Mar 14;10:105. doi: 10.3389/fnhum.2016.00105. eCollection 2016.

The alien hand syndrome (AHS) is a fascinating movement disorder. Patients with AHS experience one of their limbs as alien, which acts autonomously and performs meaningful movements without being guided by the intention of the patient. Here, we report...

Size, anisotropy and doping effects on the coercive field of ferromagnetic nanoparticles.

Journal of physics. Condensed matter : an Institute of Physics journal

Wesselinowa JM, Apostolova I.
PMID: 22049133
J Phys Condens Matter. 2007 Oct 10;19(40):406235. doi: 10.1088/0953-8984/19/40/406235. Epub 2007 Sep 21.

The influence of size, anisotropy and doping effects on the hysteresis loop of ferromagnetic nanoparticles is studied, based on the modified Heisenberg model. A Green's function technique in real space allows the calculation of the dependence of the magnetization...
