1. Does high stereotypic behavior expression affect productivity measures in sows?
ABSTRACT The objective of this study was to evaluate the effects of stereotypic behavior on productivity measures in sows. Frequent expression of stereotypies by pigs has been reported, even when pigs are not maintained in crates. This behavior is only observed in animals kept in captivity and is a wide-range welfare indicator, since it is considered to deve

2. REPRODUCTIVE EFFICIENCY AND BEHAVIOR OF PREGNANT SOWS HOUSED IN CAGES AND COLLECTIVE PENS WITH OR WITHOUT BEDDING
ABSTRACT This study aimed to evaluate the effect of wood shaving bedding on pregnant sows under two housing conditions. Sixty-four animals were distributed into four treatments, each treatment included 54 sows split into three replicates. A 2 × 2 factorial design was used (two types of housing, collective pens (CP) and combined housing (cages + CP [CCP]); a

3. Behavioral effects of endogenous or exogenous estradiol and progesterone on cocaine sensitization in female rats
Cocaine sensitization is a marker for some facets of addiction, is greater in female rats, and may be influenced by their sex hormones. We compared the modulatory effects of endogenous or exogenous estradiol and progesterone on cocaine-induced behavioral sensitization in 106 female rats. Ovariectomized female rats received progesterone (0.5 mg/mL), estradiol

4. Pharmacological evaluation of bee venom and melittin
The objective of this study was to identify the pharmacological effects of bee venom and its major component, melittin, on the nervous system of mice. For the pharmacological analysis, mice were treated once with saline, 0.1 or 1.2 mg/kg of bee venom and 0.1 mg/kg of melittin, subcutaneously, 30 min before being submitted to behavioral tests: locomotor activ

5. Animal models for predicting the efficacy and side effects of antipsychotic drugs
The use of antipsychotic drugs represents an important approach for the treatment of schizophrenia. However, their efficacy is limited to certain symptoms of this disorder, and they induce serious side effects. As a result, there is a strong demand for the development of new drugs, which depends on reliable animal models for pharmacological characterization.

6. Digestibility and behavior of dogs housed in kennels or metabolic cages
The objective of the present study was to compare the apparent digestibility coefficients of a commercial dog food, fecal consistency and behavior of dogs housed in kennels and metabolic cages. Six adult Beagle dogs were distributed in cross-over experimental design, with six replicates per treatment. Dogs were housed in two environments: metabolic cages and

8. A contribution to the study of the psychic constitution of alcoholic women / Contribuição para o estudo da constituição psíquica de mulheres alcoolistas
This study examines the psychic constitution of alcoholic women and seeks to broaden the comprehension of their psychic functioning in order to assist those who work with this population. The study uses the Rorschach test and interview analysis as assessing instruments. The participants are 15 alcohol-dependent women who have been referred to us by their own

9. A comparison of purposeless movements in psychiatric patients treated with antipsychotic drugs, and normal individuals.
Oro-facial dyskinesia and purposeless trunk and limb movements were assessed, using a standard videotape rating technique, in 182 psychiatric patients receiving antipsychotic medication, in a second sample of 43 elderly psychiatric patients also receiving antipsychotic drugs, and 85 normal, drug-naive subjects. In both the first patient sample and the group

10. A possible substrate for dopamine-related changes in mood and behavior: Prefrontal and limbic effects of a D3-preferring dopamine agonist
Dopamine can induce fascinating, complex human behavioral states, including disinhibition, euphoria, or elaborate stereotypies, whereas dopamine deficiency can cause anxiety or sadness. Limited data suggest that these phenomena may involve dysfunction of orbital frontal cortex, cingulate cortex, or ventral striatum. The dopamine D3 receptor (D3R) has an anat

11. Induction of stereotypy in dopamine-deficient mice requires striatal D1 receptor activation
Motor stereotypies are abnormally repetitive behaviors that can develop with excessive dopaminergic stimulation and are features of some neurologic disorders. To investigate the mechanisms required for the induction of stereotypy, we examined the responses of dopamine-deficient (DD) mice to increasing doses of the dopamine precursor l-DOPA. DD mice lack the
