The Society of Behavioral Medicine (SBM) supports passing the Expanding Access To Local Foods Act-a bill to promote economic opportunities for farmers and ranchers strengthen local food supply chains, increase access nutritious foods among households experiencing insecurity chronic disease risk.
Cognitive judgement bias in decision-making under ambiguity occurs both animals and humans, with some individuals interpreting ambiguous stimulus as positive (optimism) others negative (pessimism). We hypothesize that is a personality trait pessimistic would be more reactive to stressors therefore susceptible stress-related diseases than optimistic ones. Here, we show zebrafish judgment consistent behavioral over time, fish express phenotype-specific neurogenomic responses stress....
Kisspeptins are well known as mediators of the coordinated communication between brain-pituitary axis and gonads in many vertebrates. To test hypothesis that gonadal steroids regulate kiss1 kiss2 mRNA expression European sea bass (a teleost fish), we examined brains gonad-intact (Control) castrated animals, males (GDX) females (OVX) received testosterone (T) estradiol (E2) replacement, respectively, during recrudescence. In GDX males, low is observed by situ hybridization caudal hypothalamus...
Optimistic and pessimistic cognitive biases have been described in many animals are related to the perceived valence of environment. We, therefore, hypothesize that such bias can be adaptive depending on environmental conditions. In reward-rich environments, an optimistic would favoured, whereas harsh a one thrive. Here, we empirically investigated potential value using zebrafish as model. We first phenotyped female optimistic/pessimistic axis previously validated judgement assay. females...

Some animal species exhibit considerable physiological and behavioural alterations in response to captivity. It has been hypothesized, but rarely tested, that such changes reflect a negative affective state is associated this specific context. In the last years, judgement bias measures have emerged as reliable indicators of state, under assumption individuals are more likely evaluate ambiguous stimuli display therefore pessimistic behaviours. Here, we developed task for juvenile European sea...
Abstract The presence of glycosaminoglycans (GAG) has been histochemically demonstrated in the CNS various mammalian species. They have related with some nerve functions as neurotransmitters storage and synaptic transmission. In present paper, histochemical properties cell cytoplasmic GAG were studied several regions adult human CNS. Samples brain cortex, pons, upper medulla, cerebellar cortex obtained by autopsy from subjects not dying after neurological diseases fixed immersion...
ABSTRACT Reproduction is a highly demanding biological process that occurs at the optimal time of year and day to ensure success spawn offspring. Melatonin hormone that, secreted mainly by pineal gland, plays critical role in integration photoneuroendocrine information from environment (annual daily variations) modulate reproductive activity gonadal development fish. In this study we assessed effect exogenous melatonin on circadian levels sex steroids gonadotropins pubertal 2 yr-old male sea...
