Open AccessEvidence that human and equine erythrocytes could have significant roles in the transport and delivery of amino acids to organs and tissues
Erythrocytes have a well-defined role in the gaseous exchange of oxygen and carbon dioxide in the mammalian body. The erythrocytes can contain more than half of the free amino acids present in whole blood. Bas...

An Impact-Control Study to Assess the Potential Accumulation of Metals and Metalloids from Sewage Effluent and Biosolids to Sydney Rock Oysters, Saccostrea glomerata
Sewage effluent has been identified as a potential source of metal(loid) contamination in the aquatic environment. The Sydney rock oyster, Saccostrea glomerata, can accumulate most metals and is well established ...

Open AccessModelling of protein turnover provides insight for metabolic demands on those specific amino acids utilised at disproportionately faster rates than other amino acids
The nitrogen balance is regulated by factors such as diet, physical activity, age, pathogenic challenges, and climatic conditions. A paradigm was developed from published recommended rates of protein intake (g...

Open AccessSex differences in amino acids lost via sweating could lead to differential susceptibilities to disturbances in nitrogen balance and collagen turnover
Fluid collected during sweating is enriched with amino acids derived from the skin’s natural moisturising factors and has been termed “faux” sweat. Little is known about sex differences in sweat amino acid com...

Open AccessDiverse characteristics of the urinary excretion of amino acids in humans and the use of amino acid supplementation to reduce fatigue and sub-health in adults
The excretion of amino acids in urine represents an important avenue for the loss of key nutrients. Some amino acids such as glycine and histidine are lost in higher abundance than others. These two amino acid...

Exposure to 17α-ethynylestradiol causes dose and temporally dependent changes in intersex, females and vitellogenin production in the Sydney rock oyster
Although mounting evidence suggests exposure to estrogenic contaminants increases vitellogenin production in molluscs, demonstration of dose–response relationships and knowledge of the temporal nature of the v...

The Use of Lipid Metabolic Profiling to Assess the Biological Impact of Marine Sewage Pollution
Sydney rock oysters, Saccostrea commercialis, were deployed for a 3-month period at sewage-disturbed and control marine locations in the Hunter Region, New South Wales, Australia. After this period, the oysters...

The detection of pollutant impact in marine environments: Condition index, oxidative DNA damage, and their associations with metal bioaccumulation in the Sydney rock oyster Saccostrea commercialis
Specimens of the Sydney rock oyster Saccostrea commercialis were deployed for a 3-month period at control and sewage disturbed marine locations in the Hunter Region, New South Wales, Australia. The DNA damage pro...

Differential bioaccumulation of heavy metals and organopollutants in the soft tissue and shell of the marine Gastropod, Austrocochlea constricta
Austrocochlea constricta (Gastropodia) has the potential to act as a useful biomonitoring system of pollutants in the marine environment. The organism was used in the present study to investigate the distributio...

Bioaccumulation of pollutants and changes in population parameters in the gastropod mollusc Austrocochlea constricta
The gastropod mollusc Austrocochlea constricta was collected from four marine locations within the Newcastle region of New South Wales, Australia to assess the range and distribution of major bioaccumulated organ...

The mechanism of phosphonic (phosphorous) acid action in Phytophthora
Phosphonates exhibit a complex mode of action in their control of fungi. Using Phytophthora palmivora as a model, we have shown that phosphonate anion can act directly on the fungus, reducing growth, and that gro...
