Food‐solicitation displays in nestling birds: still begging for answers
ABSTRACT Nestling begging is a key model for understanding animal communication and parent–offspring conflict. Dynamic begging displays are often interpreted as costly, honest signals of need, with honesty maintained by viability costs, as proposed in Godfray's influential signalling model.

We previously reported that the citrus flavonoid 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF) increased the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus of a transient global ischemia mouse model.

Corticosterone in Lymphoma-Bearing Rats.
SummaryCorticosterone in plasma and urine was determined by spectrofluorometry in sulfuric acid and by direct spectrophotometry in ethanol. Plasma levels and urinary excretion of corticosterone were elevated in rats with subcutaneous lymphomas. The high plasma concentration of corticosterone in these rats may help to explain the reduction in splenic ...

Perinatal Changes in Liver Corticosterone, Serum Insulain and Plasma Glucagon and Corticosterone in the Rat [PDF]
This report describes some hormonal changes occuring in the rat during the last 3 days of gestation and the first 6 h after surgical deliversy on days 20–22uu ofgestation. In the foetus, the concentration of glucagon increased 2‐fold and that of insulin decreaed from 4.7 to 3.5 ng/ml between days 21 and 22. Consequently the insulin/glucagon molar ratio

The influence of circadian variables on ecotoxicology metabolomics
ABSTRACT Ecotoxicologists are using metabolomics increasingly to gain insight into toxicological mechanisms and sublethal effects of chemical exposures. Metabolomics offers a sensitive multi‐parameter approach that can detect biochemical responses not obvious using apical and behavioural endpoints.

Measurement of corticosterone in mice: a protocol for a mapping review [PDF]
Severity assessment for experiments conducted with laboratory animals is still based mainly on subjective evaluations; evidence-based methods are scarce. Objective measures, amongst which determination of the concentrations of stress hormones, can be used to aid severity assessment.

Modulation of the hypothalamic-pituitary-adrenal axis of an Arctic-breeding polygynandrous songbird, the Smith's longspur, Calcarius pictus [PDF]
To successfully reproduce in the Arctic, birds must modulate their neuroendocrine and behavioural systems. These adjustments include an attenuation of the stress responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis to external stimuli and a ...
