First-principle molecular dynamics with ultrasoft pseudopotentials: parallel implementation and application to extended bio-inorganic system

open access: yes, 2003
We present a plane-wave ultrasoft pseudopotential implementation of first-principle molecular dynamics, which is well suited to model large molecular systems containing transition metal centers.

Comparative Effects of Three Microbial Starter Cultures on the Physicochemical and Sensory Quality of Fermented Sausages

open access: yesFood Bioengineering, EarlyView.
ABSTRACT This study innovatively links specific microbial compositions of commercial starter cultures to the evolution of key odorant and taste‐active amino acids, revealing the underlying mechanisms behind distinct flavor profiles. Three microbial starter cultures—Saccharomyces cerevisiae (SC), Scarlet (ST), and Roxaane LC (LC), were added to sausages,

Site-Directed Mutagenesis of Myoglobin for Studies of Their Interaction with Iron(III) by Multi-Spectroscopic Techniques

open access: yesJournal of Spectroscopy, 2013
In order to investigate how the amino acids on the surface of myoglobin molecule influence myoglobin's structure and function, a variety of spectroscopy techniques were applied in the study of the interaction between Fe(III) and myoglobin (wild type and ...

Development of methods for capillary isoelectric focusing of dairy proteins : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Chemistry at Massey University [PDF]

open access: yes, 2006
Capillary Isoelectric Focusing (CIEF) is a high-resolution technique which can be applied to the separation and characterisation of complex biological mixtures such as dairy proteins.

The effect of inhomogenities on single molecule imaging by hard XFEL pulses

open access: yes, 2009
We study the local distortion of the atomic structure in small biological samples illuminated by x-ray free electron laser (XFEL) pulses. We concentrate on the effect of inhomogenities: heavy atoms in a light matrix and non-homogeneous spatial ...

Influence of dietary vitamin E supplementation on cholesterol oxidation and fresh colour in beef aged for 3 and 14 days [PDF]

open access: yes, 2016
The effects of dietary vitamin E supplementation on the susceptibility to lipid oxidation and colour of the Longissimus thoracis (LT) muscle aged in vacuum packaged conditions for 3 or 14 days were studied.

Effect of Using Nisin and Ethylenediaminetetraacetic Acid on the Bacterial Load, Deterioration Criteria, and Sensory Attributes of Chilled Chicken Cuts

open access: yesFood Safety and Health, EarlyView.
Evaluation of the efficacy of selected dipping solutions on fresh chicken meat shelf life. Samples treated with nisin and EDTA combinations, followed by chilled storage. The effectiveness of these interventions was assessed through bacteriological, sensory, and physicochemical (pH) deterioration criteria.

High Sensitivity Cardiac Troponin I Detection via MP‐Locked Aptamer and Multimeric DNAzyme‐Coupled Hyperbranched Hybridization Chain Reaction

open access: yesSmall, EarlyView.
We report a magnetic particle anchored locked aptamer platform integrated with hyperbranched HCR and DNAzyme amplification for enzyme‐free, ultrasensitive detection of cardiac troponin I. The assay achieves a 0.25 ng/L detection limit within 25 minutes and enables cross‐species MI detection, with machine learning classification reaching 90% accuracy ...

Myoglobin clearance with continuous veno-venous hemodialysis using high cutoff dialyzer versus continuous veno-venous hemodiafiltration using high-flux dialyzer: a prospective randomized controlled trial

open access: yesCritical Care, 2020
Background Myoglobin clearance in acute kidney injury requiring renal replacement therapy is important because myoglobin has direct renal toxic effects.

Magnetic susceptibility anisotropy of myocardium imaged by cardiovascular magnetic resonance reflects the anisotropy of myocardial filament α-helix polypeptide bonds. [PDF]

open access: yes, 2015
BackgroundA key component of evaluating myocardial tissue function is the assessment of myofiber organization and structure. Studies suggest that striated muscle fibers are magnetically anisotropic, which, if measurable in the heart, may provide a tool ...
