It is a potent antiemetic and is used in the treatment of intractable HICCUPS. (From AMA Drug Evaluations Annual, 1994, p279)Infant Care: Care of infants in the home or institution.Health Behavior: Behaviors expressed by individuals to protect, maintain or promote their health status. For example, proper diet, and appropriate exercise are activities perceived to influence health status. Life style is closely associated with health behavior and factors influencing life style are socioeconomic, educational, and cultural.Behavior: The observable response of a man or animal to a situation.Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.Stress, Psychological: Stress wherein emotional factors predominate.Sexual Behavior: Sexual activities of humans.Prolactin: A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD.

Physiologically it is probably involved in RAGE reactions, the LORDOSIS REFLEX; FEEDING responses, bladder tonus, and pain.Rats, Sprague-Dawley: A strain of albino rat used widely for experimental purposes because of its calmness and ease of handling. It was developed by the Sprague-Dawley Animal Company.Parenting: Performing the role of a parent by care-giving, nurturance, and protection of the child by a natural or substitute parent. The parent supports the child by exercising authority and through consistent, empathic, appropriate behavior in response to the child's needs. PARENTING differs from CHILD REARING in that in child rearing the emphasis is on the act of training or bringing up the children and the interaction between the parent and child, while parenting emphasizes the responsibility and qualities of exemplary behavior of the parent.Survival: Continuance of life or existence especially under adverse conditions; includes methods and philosophy of survival.Rats, Long-Evans: An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.Neurosecretory Systems: A system of NEURONS that has the specialized function to produce and secrete HORMONES, and that constitutes, in whole or in part, an ENDOCRINE SYSTEM or organ.Housing, AnimalCallithrix: A genus of the subfamily CALLITRICHINAE occurring in forests of Brazil and Bolivia and containing seventeen species.Video Recording: The storing or preserving of video signals for television to be played back later via a transmitter or receiver.

Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Ovariectomy: The surgical removal of one or both ovaries.Epilepsy, Absence: A childhood seizure disorder characterized by rhythmic electrical brain discharges of generalized onset. Clinical features include a sudden cessation of ongoing activity usually without loss of postural tone. Rhythmic blinking of the eyelids or lip smacking frequently accompanies the SEIZURES. The usual duration is 5-10 seconds, and multiple episodes may occur daily. Juvenile absence epilepsy is characterized by the juvenile onset of absence seizures and an increased incidence of myoclonus and tonic-clonic seizures. (Menkes, Textbook of Child Neurology, 5th ed, p736)Adolescent Behavior: Any observable response or action of an adolescent.Hypothalamus: Ventral part of the DIENCEPHALON extending from the region of the OPTIC CHIASM to the caudal border of the MAMMILLARY BODIES and forming the inferior and lateral walls of the THIRD VENTRICLE.Receptor, Serotonin, 5-HT2A: A serotonin receptor subtype found widely distributed in peripheral tissues where it mediates the contractile responses of variety of tissues that contain SMOOTH MUSCLE.

CRH is synthesized by neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, CRH stimulates the release of ACTH from the PITUITARY GLAND. CRH can also be synthesized in other tissues, such as PLACENTA; ADRENAL MEDULLA; and TESTIS.Stereotyped Behavior: Relatively invariant mode of behavior elicited or determined by a particular situation; may be verbal, postural, or expressive.Analgesics: Compounds capable of relieving pain without the loss of CONSCIOUSNESS.Dopamine Antagonists: Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.Nucleus Accumbens: Collection of pleomorphic cells in the caudal part of the anterior horn of the LATERAL VENTRICLE, in the region of the OLFACTORY TUBERCLE, lying between the head of the CAUDATE NUCLEUS and the ANTERIOR PERFORATED SUBSTANCE. It is part of the so-called VENTRAL STRIATUM, a composite structure considered part of the BASAL GANGLIA.Cocaine: An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.Body Weight: The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.Locomotion: Movement or the ability to move from one place or another. It can refer to humans, vertebrate or invertebrate animals, and microorganisms.Estrogens: Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL.

It is expressed by units of pounds or kilograms.Progesterone: The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.Agonistic Behavior: Any behavior associated with conflict between two individuals.Risk-Taking: Undertaking a task involving a challenge for achievement or a desirable goal in which there is a lack of certainty or a fear of failure. It may also include the exhibiting of certain behaviors whose outcomes may present a risk to the individual or to those associated with him or her.Pregnancy Complications: Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.Age Factors: Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.Prenatal Care: Care provided the pregnant woman in order to prevent complications, and decrease the incidence of maternal and prenatal mortality.Serotonin Receptor Agonists: Endogenous compounds and drugs that bind to and activate SEROTONIN RECEPTORS. Many serotonin receptor agonists are used as ANTIDEPRESSANTS; ANXIOLYTICS; and in the treatment of MIGRAINE DISORDERS.

Charles Ottley Groom NapierSociety for Behavioral Neuroendocrinology: The Society for Behavioral Neuroendocrinology is an interdisciplinary scientific organization dedicated to the study of hormonal processes and neuroendocrine systems that regulate behavior.Dog aggression: Dog aggression is a term used by dog owners and breeders to describe canine-to-canine antipathy. Aggression itself is usually defined by canine behaviorists as "the intent to do harm".Oxytocin receptor: The oxytocin receptor, also known as OXTR, is a protein which functions as receptor for the hormone and neurotransmitter oxytocin. In humans, the oxytocin receptor is encoded by the OXTR gene which has been localized to human chromosome 3p25.L-371,257Nest (protein structural motif): The Nest is a type of protein structural motif. Peptide nests are small anion-binding molecular features of proteins and peptides.Male lactation: Male lactation in zoology means production of milk from mammary glands in the presence of physiological stimuli connected with nursing infants. It is well documented in the Dayak fruit bat.Genetics of social behavior: The genetics of social behavior is an area of research that attempts to address the question of the role that genes play in modulating the neural circuits in the brain which influence social behavior. Model genetic species, such as D.Curiosity: Curiosity (from Latin curiosus "careful, diligent, curious," akin to cura "care") is a quality related to inquisitive thinking such as exploration, investigation, and learning, evident by observation in human and animal species. Curiosity is heavily associated with all aspects of human development, in which derives the process of learning and desire to acquire knowledge and skill.Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Median preoptic nucleus: The median preoptic nucleus is located dorsal to the other three nuclei of the preoptic area of the anterior hypothalamus. The hypothalamus is located just beneath the thalamus, the main sensory relay station of the nervous system, and is considered part of the limbic system, which also includes structures such as the hippocampus and the amygdala.Maternal bond: A maternal bond or motherly bond is generally the relationship between a mother and her child.NS-2710: NS-2710 (LS-193,970) is an anxiolytic drug with a novel chemical structure, developed by the small pharmaceutical company Neurosearch. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.Peripartum cardiomyopathySexual motivation and hormones: Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviours.Mothers TalkHaloperidolBehavior: Behavior or behaviour (see spelling differences) is the range of actions and [made by individuals, organism]s, [[systems, or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the response of the system or organism to various stimuli or inputs, whether [or external], [[conscious or subconscious, overt or covert, and voluntary or involuntary.Desmethylclozapine: N-Desmethylclozapine (NDMC), or norclozapine, is a major active metabolite of the atypical antipsychotic drug clozapine. Unlike clozapine, it possesses intrinsic activity at the D2/D3 receptors, and acts as a weak partial agonist at these sites similarly to aripiprazole and bifeprunox.Stressor: A stressor is a chemical or biological agent, environmental condition, external stimulus or an event that causes stress to an organism.Prolactin cellNeonatal Behavioral Assessment Scale: The Neonatal Behavioral Assessment Scale (NBAS),also known as the Brazelton Neonatal Assessment Scale (BNAS),Kaplan, R. M.Hypervigilance: Hypervigilance is an enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviors whose purpose is to detect threats. Hypervigilance is also accompanied by a state of increased anxiety which can cause exhaustion.Transactivation: In the context of gene regulation, transactivation is increased rate of gene expression triggered either by biological processes or by artificial means, through expressing an intermediate (transactivator) protein. In the context of receptor signaling, transactivation occurs when one or more receptors activates another; receptor transactivation may result from crosstalk of their signaling cascades.Another Grey Area: Another Grey Area is a 1982 album by Graham Parker and was released on the Arista Records label.

(1/1163) Predicting developmental outcomes at school entry using a multiple-risk model: four American communities. The Conduct Problems Prevention Research Group.

The contributions of different risk factors in predicting children's psychological and academic outcomes at the end of 1st grade were examined. Using a regression model, levels of ecobehavioral risk were assessed in the following order: specific demographics, broad demographics, family psychosocial status, mother's depressive symptoms, and neighborhood quality. Participants were 337 families from 4 American communities. Predictor variables were assessed in kindergarten, and teacher, parent, and child outcomes (behavioral and academic) were assessed at the end of 1st grade. Results indicated that (a) each level of analysis contributed to prediction of most outcomes, (b) 18%-29% of the variance was predicted in outcomes, (c) a common set of predictors predicted numerous outcomes, (d) ethnicity showed little unique prediction, and (e) the quality of the neighborhood showed small but unique prediction to externalizing problems.  (+info)

(2/1163) Regulation of maternal behavior and offspring growth by paternally expressed Peg3.

Imprinted genes display parent-of-origin-dependent monoallelic expression that apparently regulates complex mammalian traits, including growth and behavior. The Peg3 gene is expressed in embryos and the adult brain from the paternal allele only. A mutation in the Peg3 gene resulted in growth retardation, as well as a striking impairment of maternal behavior that frequently resulted in death of the offspring. This result may be partly due to defective neuronal connectivity, as well as reduced oxytocin neurons in the hypothalamus, because mutant mothers were deficient in milk ejection. This study provides further insights on the evolution of epigenetic regulation of imprinted gene dosage in modulating mammalian growth and behavior.  (+info)

(3/1163) Preparing for the next round: convalescent care after acute infection.

Infections pose a nutritional stress on the growing child. No therapeutic goal is as important as the rapid recovery of preillness weight after acute infections. Successful convalescence, with supernormal growth rates, can be achieved with relatively brief periods of intensive refeeding, offsetting any tendency toward reduced immune defenses or other nutritionally determined susceptibilities to further infection. Since the mother is the only person who can effectively manage convalescent care, she must be given specific tasks with measurable targets in order to reliably oversee the child's rehabilitation. Not generally considered in the realm of preventive medicine, effective home-based convalencent care is the first crucial step in preventing the next round of illness. An approach to the widespread mobilization of mothers to monitor and sustain their children's growth is proposed in this paper. Rather than a passive recipient of health services, the mother becomes the basic health worker, providing diagnostic and therapeutic primary care for her child. Only the mother can break the malnutrition-infection cycle.  (+info)

(4/1163) Interaction of late pregnancy and lactation in rats.

The effect of pregnancy on lactation was studied during the third week of lactational pregnancy in postpartum pregnant rats with a delay in implantation of only 1 day (1d-LP rats). In an experimental design in which the suckling litter was prevented from consuming solid food, lactational performance was estimated by weighing the ten-pup suckling litters on days 16-21 of lactation or by measuring maternal weight loss after a nursing spell on day 21. In 1d-LP rats, food consumption as well as lactational performance was lower than it was in nonpregnant lactating rats (L rats) and pregnant-lactating rats with a normal long delay of implantation of at least 6 days (LP rats). The time spent by the pups sucking at the nipples was not different among the three groups, but the number of milk ejections was diminished in 1d-LP dams. Restriction of daily food supply during days 16 to 21 of lactation diminished lactational performance more strongly in 1d-LP rats than it did in L rats; 1d-LP rats conserved protein stores and mobilized fewer minerals than did L rats. The weight and composition of the litter in vitro were not affected by the food restriction. In pregnant-lactating rats (LP and 1d-LP rats), the number of early resorptions was increased in comparison with pregnant rats, showing that lactation can affect the earlier stages of pregnancy. It was concluded that late pregnancy does not affect nursing behaviour, but suppresses lactation by restricting maternal food intake and mobilization of maternal stores. Measurements in serum indicate a causative role for oestradiol, but not for leptin.  (+info)

(5/1163) Second generation effects of maternal ethanol consumption on immunity to Trichinella spiralis in female rats.

The deleterious effects of maternal ethanol consumption on neonatal immune development and early immune responses has been well documented. However, the effects of such neonatal exposure to maternally consumed ethanol on the neonates' immune responses in their adult life, especially in combination with additional ethanol exposure, has received little attention. For these experiments, female rats were fed on either 6% ethanol or pair-fed isocaloric control Lieber-DeCarli liquid diets for 30 days prior to, and during, pregnancy and lactation. One day after weaning their pups, the mothers were infected with 1000 Trichinella spiralis larvae, and maintained on diets for an additional 20 days. At this time, they were challenged with 2000 T. spiralis larvae, killed 3 days later, and their immune status determined. These animals served as the first generation alcohol animals. Their female offspring served as the experimental second generation animals. These animals received maternal ethanol during pregnancy and lactation and control diet during their juvenile period (from weaning to 90 days of age). They were then subjected to a schedule of ethanol or pairfeeding, identical to the first generation dams. Two groups of second generation animals were established: Group 1 was exposed to ethanol during their dam's pregnancy and lactation periods only, with no subsequent ethanol treatment; Group 2 received ethanol during their dam's pregnancy and lactation periods and then again throughout their adult experimental period. Our previous studies showed only minimal changes following a secondary challenge in T. spiralis-immunized rats; however, neonates born to alcohol-consuming mothers did show some depressed secondary immune responses when challenged soon after weaning. We chose to use a secondary immune challenge to assess further immune alterations in second generation adult animals. No differences between any of the ethanol and pair-fed groups were observed in intestinal worm burdens, which is similar to data previously reported for adult alcohol-consuming animals. However, second generation group 2 animals demonstrated significantly reduced proliferation responses to T. spiralis antigen and Concanavalin A (Con A) stimulation relative to the ethanol first generation and to the second generation Group 1 animals. This group also demonstrated significantly lower absorbencies in the ELISA assay for specific IgM and IgG anti-T. spiralis antibodies than the pair-fed, ethanol first and second generation Group 1 animals. The proportion of total T cells and cytotoxic T cells was significantly lower and the proportion of natural killer cells was elevated in both second generation ethanol Groups 1 and 2 relative to the ethanol first generation and pair-fed groups. In addition, Group 2 second generation animals showed significantly lower proportions of total leukocytes and T cells than Group 1 second generation animals. Although secondary immune responses to T. spiralis infection were not altered in rats exposed to ethanol only as adults, exposure to maternal ethanol does affect some specific immune responses in second generation adult life and maternal exposure may exert cumulative immune effects in concert with later consumption of ethanol by offspring born to alcoholic mothers.  (+info)

(6/1163) Maternal effort and male quality in the bank vole, Clethrionomys glareolus.

Parental investment in reproduction is adjusted according to potential benefits in terms of offspring survival and/or mating success. If male quality affects the reproductive success of a female, then females mating with high-quality males should invest more in reproduction. Although the subject has been of general interest, further experimental verification of the hypothesis is needed. We studied whether female bank voles (Clethrionomys glareolus) adjusted their maternal effort according to male quality, measured as mating success. To enable the measurement of maternal effort during nursing separately from male genetic effects the litters were cross-fostered. Further, the genetic background of male quality was examined. Male quality did not correlate with litter size or offspring size at birth. Offspring growth was positively related to food consumption and milk production of mothers. However, these direct measurements of maternal effort were independent of male quality. Male mating success appeared to be significantly heritable indicating that there are genetic benefits. Still, females did not adjust maternal effort according to the genetic quality of their offspring. We suggest that female bank voles gain significant genetic benefits from mating with high-quality males whereas they cannot improve their reproductive success by increasing maternal effort.  (+info)

(7/1163) Butorphanol tartrate acts to decrease sow activity, which could lead to reduced pig crushing.

The objective of this study was to determine whether administration of an analgesic to sows immediately after farrowing would allow them to lie more restfully. Sows lying on their pigs, causing them to be "crushed," is a major cause of pig mortality. Most deaths due to crushing occur during the first 3 d postpartum. For modern, lean-type sows, farrowing crates are relatively hard and unforgiving, even though they may be equipped with plastic-coated, expanded metal flooring. Indeed, many sows develop pressure sores on their shoulders, and this may contribute to the sows' discomfort. These sores may cause a sow to change position frequently to alleviate pain, thus increasing its chances of crushing pigs. Sixteen production sows were assigned to either a control group (C, n = 8) with litter size 11.71+/-.78 or an experimental group (B, n = 8) with litter size 11.63+/-1.22. Pigs born to C and B sows weighed 1.60+/-.04 and 1.37+/-.04 kg, respectively. The C sows were given no treatment, whereas the B sows were administered an i.m. injection of butorphanol tartrate at a dose of .15 mg/kg BW every 6 h until 3 d after farrowing. Data were collected on all sows using time-lapse photography (1 frame/.4 s) for a 3-d duration upon the initiation of farrowing. To assess the degree of comfort of each sow, body position changes were recorded when sows switched between lying, sitting, and standing. Data were analyzed by 12-h periods using Wilcoxon-Mann-Whitney equations. During the 72-h period, B sows tended to perform fewer position changes than C sows (P = .10). Specifically, position changes were fewer for B sows from 48 to 72 h postpartum (P<.06). There were no differences in position changes between treatments from 0 to 48 h postpartum (P>.50). There was no difference in the rate of crushing between treatments (C = 5, B = 5). The butorphanol did not seem to affect pig activity or normal behaviors or to create adverse effects, such as diarrhea. Although the sows given butorphanol showed a reduced number of position changes, the dose was intermediate, and a higher dose may have a greater effect. If pig mortality can be decreased, an analgesic protocol that is simple to administer and readily available to producers can be developed. Alternatively, using of more pliable flooring or an increase in sow body fat may allow sows to lie more stationary.  (+info)

(8/1163) Danger to pigs due to crushing can be reduced by the use of a simulated udder.

Sows that lie on their young, pig "crushing", is a significant cause of pig mortality in current production systems. Although mortality rates of pigs in farrowing crates are lower than mortality rates of pigs in pens, loss due to crushing is still estimated to be between 4.8 and 18%. During the first few days after parturition, pigs are highly attracted to the odor of their dam's udder. Thus, our research was designed to move the pigs away from the sow by competing with the sow's udder using a "simulated" udder. Fifteen Yorkshire x Landrace sows and their litters (11.4+/-.78 pigs) were assigned to either a control (C, n = 9) or an experimental group (SU, n = 6). The C pigs had access to a heat lamp, whereas the SU pigs' crate had a simulated udder. Data were collected using time-lapse photography (1 frame/.4 s) for a 3-d duration at the initiation of farrowing. When a sow stood, data were recorded by 1-min scan samples to record the number of pigs using either the heat lamp or the simulated udder. In addition, stillborn pigs, pig crushing, and death by other means also were recorded. Data were analyzed by 12-h periods using generalized estimating equations. Results indicate that from 12 to 72 h postpartum, excluding 24 to 36 h postpartum, the estimated probability that pigs were in a safe area (simulated udder or heat lamp) was .89 for SU pigs, compared with only .72 for C pigs (P = .005). During the 24- to 36-h period, it was more probable to find pigs on a simulated udder (.77) than under only a heat lamp (.61, P = .016). Stillborn pigs, pig crushing, and death by other means were not different between treatments (mean = .87, .60, 1.2; P>.20). The simulated udder drew pigs away from the sow's udder better than heat lamps alone. Considering these findings, mortality of pigs due to crushing may be decreased substantially using a simulated udder. These results are promising, but further refinement should be done, including improved udder design and investigation of the attractiveness of various stimuli.  (+info)
