Oxidative stress biomarkers in dementia
… thus far suggests that increased levels of oxidative stress and vascular risk factors are two major contributors, amongst others, to AD development. The thesis aimed to investigate markers of oxidative stress in AD plasma. Moreover, the oxidative status of specific proteins was investigated …

Oxidative stress and seed survival
… with a view to determining the role of oxidative stress as a diagnostic marker for desiccation tolerance.<br/>Axes of non-senescent highly viable recalcitrant seeds of horse chestnut were metabolically active, contained products of lipid peroxidation, displayed low levels of enzymatic …

Oxidative stress in anoxic habitats
… enzymes. Virtually all life forms experience oxidative stress to some degree, and they are all equipped with mechanisms to protect themselves and to repair the damaged moieties. While oxidative stress is an obvious caveat of oxic life, it can also affect the organisms in anoxic environments …

Methamphetamine: Airborne analysis and oxidative destruction
This thesis investigates two chemical aspects of the remediation of former clandestine methamphetamine laboratories: developing methods for detecting airborne methamphetamine with short (ca. 20 min) sampling times, and oxidation of methamphetamine as a possible decontamination method. Dynamic solid …

Interactions between oxidative stresses in corn
… mays L.). Ozone is the prototypical inducer of oxidative stress, which involves reactive oxygen species (ROS) production, scavenging and signaling, and is a major form of plant stress present in field conditions during crop production. Previous work has shown the importance of the plant's …

Oxidative Heck Reactions with Terminal Olefins
… catalyzed Heck reaction is performed under oxidative, acidic conditions and proceeds with good yields and excellent regio- and stereoselectivities to generate linear E-arylated olefins. Polyenes are prevalent motiefs in natural products and pharmaceuticals. Polyene functionality often …

Role of oxidative stress in photoreceptor degeneration
… and represent the major cellular source of oxidative stress. ROS are capable of attacking molecules such as DNA, proteins and lipids, and of compromising either the structural and functional integrity or the survival of cells. Mitochondria also play a key role in apoptosis, the major …

Oxidative damage to recombinant proteins during production
… their properties; among these modifications, oxidative damage is one of the most ubiquitous. Oxidative damage, however, is only occasionally considered as a "quality concern" since it rarely detectable using standard biochemical techniques. The production of an oxidatively-sensitive protein, …

Oxidative stability of Menhaden/Soybean oil blends
With the approval of menhaden oil pending, the food industry is trying to incorporate marine oils high in omega-3 fatty acids into food systems. The main problem obstructing its use as a food ingredient is fishy/painty flavors which occur with low levels of oxidation. The purpose of this study was …

Kinetics of Arsenopyrite Oxidative Dissolution by Oxygen
The objective of this study is to use a mixed flow reactor system to determine the dissolution rate and infer potential mechanisms of arsenopyrite (FeAsS) oxidation by dissolved oxygen at 25°C and circumneutral pH. Release rates for iron, arsenic and sulfur are calculated for a variety of initial …
