Oxidative Cost of Reproduction


The physical “costs” of reproduction to an organism, particularly under less than ideal conditions, have been the subject of many studies in recent years.  Theories suggest the physical investment in a pregnancy may sometimes come at the cost of either individual survival or future reproductive events.  … » Read More

Fecal Glucocorticoid Measurements to Monitor Situational Stress


Thanks to many years of careful planning and habitat restoration, several species including Black footed ferrets, California condors, Grey wolves, Musk ox, Golden eagles and Northern river otters have been or are being reintroduced into areas of their range where historic populations have disappeared or greatly diminished due to pressure from various human activities.  … » Read More

Cystatin C as a Marker for Renal function

Glomular Filtration Rate (GFR) is the metric normally used to assess kidney function. It can be determined either by measuring the concentration of endogenous markers such as urea nitrogen or creatinine in serum, or by measuring the clearance rate of exogenous indicators such as inulin, iohexol or 51Cr-EDTA or 125I-iothalamate.… » Read More

Time of Day Influences Inflammatory Response to Cytotoxic Chemotherapy



It has been demonstrated cancer chemotherapy depends on administration of treatment at times that coincide with both optimal drug metabolism and cellular processes such as apoptosis, DNA repair and changes to cell cycle progression. Given we know immune response is also strongly influenced by circadian cycles, it seems reasonable to consider the possibility that the daily cycles of cytokines and immune response proteins may also contribute to the effectiveness of chemotherapeutics. … » Read More

Monitoring Reproductive Status in Bird Feces

Monitoring of reproductive endocrinology is a very important tool in the management of animal populations both in captivity and in the wild.   Whenever possible measuring key indicators such as estrogens, progestogens, and androgens using non-invasive sample types is prefered so that animals under study are not subjected to the stress of handling and blood collection.… » Read More

Adapting to Climate Change


Stress and mineralization responses to environmental stress in Mantis Shrimp

Calcified marine organisms face a double edged sword as global warming increases not only the temperature of ocean waters, but also the level of acidification.  Many such organisms that live within the intertidal zone are already adapted to cope with the broad fluctuations in temperature and pH that occur with each tidal cycle – but precisely how the species cope with the stressors of increased temperature and decreased pH varies widely and have costs that can include increased energy demands, growth restriction, physiological stress, and changes in mineralization. … » Read More

The Role of Thyroxine in Photo Stimulation

Changes in the length of day throughout the year can be a marker for critical species functions such as migration, hibernation, and mating.  These changes have been shown to affect an organism’s morphology and hormones as well as other biomarkers. For example, the thyroid hormones T3 and T4 have previously been demonstrated to have roles in the regulation of photoperiod response in birds.  … » Read More

New! – Allopregnanolone EIA Kit, Monoclonal Antibody Based

Allopregnanolone is made from progesterone which is converted into 5α-dihydroprogesterone by 5α-reductase type I, and 3α-hydroxysteroid oxidoreductase isoenzymes. This 5α-dihydro intermediate is then converted into allopregnanolone. 3α-hydroxysteroids do not interact with classical intracellular steroid receptors but bind stereoselectively and with high affinity to receptors for the major inhibitory neurotransmitter in brain, γ-amino-butyric acid (GABA). … » Read More

New Human Myeloperoxidase EIA kit





Myeloperoxidase (MPO) is a tetrameric heme-containing protein abundantly produced in neutrophil granulocytes where it plays an important anti-microbial role.  Normally stored in azurophilic granules, MPO is released into the extracellular space during degranulation. There, as part of the neutrophils “respiratory burst” it produces hypochlorous acid from hydrogen peroxide and Cl.… » Read More

Aldosterone: Regulating Blood Pressure

Aldosterone is a steroid hormone primarily involved in the regulation of sodium and potassium levels in blood as part of the renin-angiotensin system (RAS). Aldosterone increases reabsorbation of sodium from the tubular epithelial cells of kidneys back into the blood, while at the same time moving potassium ions from the blood into the kidneys for eventual excretion in urine.… » Read More

Corticosterone: Ruling out stress
