One of the most important topics in attentional and emotional modulation of cardiac responses is time course of cardiac chronotropic response. The reason lies in dual innervation of heart, which leads to occurrence of several phases of cardiac response during exposure to affective stimuli, determined by the balance of sympathetic and parasympathetic influences. Cardiac chronotropic reactivity thus represents quite effective measure capable to trace the moment when attending and orienting processes (i.e., sensory intake of stimulus) prime relevant behavioral response (ile., emotion with approach or avoidance tendencies). The aim of this study was to find the time course of heart rate (HR) responses typical for negative (disgust, surprise, fear, anger) and positive (happiness, pleasant erotic) affective pictures and to identify cardiac response dissociation for emotions with different action tendencies such as "approach" (surprise, anger, happiness) and "avoidance" (fear, sadness, disgust). Forty college students participated in this study where cardiac responses to slides from IAPS intended to evoke basic emotions (surprise, fear, anger, sadness, disgust, happiness, pleasant-erotic). Inter-beat intervals of HR were analyzed on every 10 sec basis during 60 sec long exposure to affective visual stimuli. Obtained results demonstrated that differentiation was observed at the very first 10s of exposure (anger-fear, surprise-sad, surprise-erotic, surprise-happiness paris), reaching the peak of dissociation at 30s (same pairs plus surprise-disgust and surprise-fear) and was still effective for some pairs (surprise-erotic, surprise-sad) even at 50s and 60s. discussed are potential cardiac autonomic mechanisms underlying attention and emotion processes evoked by affective stimulation and theoretical considerations implicated to understand the role of differential cardiac reactivity in the behavioral context (e.g., approach-avoidance tendencies, orienting-defense responses).

The objective of the investigation was to study the effect of intramuscular $PGF_2\;{\alpha}$ and GnRH on estrus behavior and ovarian response in Murrah buffalo heifers. Twelve Murrah buffalo heifers at 32 months of age that had not exhibited behavioral estrus symptom were included in the experiment. Out of 12,4 heifers were in follicular phase (plasma estradiol $57.05{\pm}12.52pg/ml$), another 4 heifers were in luteal phase (Plasma progesterone $2.24{\pm}0.25ng/ml$) while the ovaries of remaining four heifers were inactive (estradiol $23.70{\pm}1.66pg/ml$and progesterone $0.32{\pm}0.06ng/ml$). $PGF_2\;{\alpha}$ (25 mg, Lutalyse, im) and GnRH (200 ug, Fertagyl, iv) was administered to each heifer at interval of 10 days. The plasma progesterone concentration decreased within 48 hrs after $PGF_2\;{\alpha}$ injection and followed thereafter with follicular growth, estrus and ovulation. GnRH administration induced follicular growth, elevation of plasma estradiol concentration with subsequent exhibition of behavioral estrus in 2 out of 4 heifers having inactive ovary. The observation reveals that Murrah buffalo heifers at 32 months of age have developed receptors for $PGF_2\;{\alpha}$ and GnRH on ovarian and pituitary tissue respectively and response the single injection of $PGF_2\;{\alpha}$ and GnRH similar to the mature cycling animals.

Objectives : This study examined the relationship of parent-related negative life events with mental health and delinquent behaviors among Korean adolescents. Methods : A total of 2,976 high school first-grade pupils (1,498 boys & 1,478 girls) taking part in the third wave of Korean Youth Panel Survey completed a self-administered questionnaire regarding parent-related life events, depressive feelings, suicidal ideation, delinquent behaviors, demographic characteristics, parental socioeconomic status, social support, and social capital. Data analyses were conducted using multivariate logistic regression. Results : After adjusting for all covariates, the more parent-related negative life events adolescents experienced throughout their whole life, the more likely adolescent were to have mental and behavioral problems. A significant dose-response relationship between them was more clearly observed in girls than in boys. The experience of parentrelated negative events during childhood was significantly associated with suicidal ideation and delinquent behaviors for boys, and with depressive feelings for girls during adolescence. Indeed, parental social support, social capital, and having a close friend with delinquent behaviors, especially for girls, partially mediated the relationship between parent-related negative life events and both outcomes. Conclusions : The study showed a clear dose-response relationship of frequency of parent-related negative life events with poor mental and behavioral health for both genders. The residual effect of being exposed to parent-related events during childhood on mental health and delinquent behaviors during adolescence still remained.

The phototactic behavioral responses of Tribolium castaneum adults to light-emitting diodes (LEDs) of seven different wavelengths were determined under various conditions (light exposure times, light sources, and luminance intensities) and compared with those of a black light bulb (BLB) under laboratory conditions. Based on the attractive rate (%) of T. castaneum adults under optimal conditions (50 lx and an 48 h exposure time) in the dark, red LED ($625{\pm}10nm$) exhibited the highest potential attractive rate (97.8 %), followed by yellow ($590{\pm}5nm$, 68.9 %), green ($520{\pm}5nm$, 55.6 %), infrared (IR) (730 nm, 54.4 %), white (450-620 nm, 41.1 %), blue ($470{\pm}10nm$, 34.4 %), and ultraviolet (UV) (365 nm, 0.06 %) LEDs. In comparison, red LED (97.8 %) was approximately 3.4 times more attractive to T. castaneum adults than the BLB (28.9 %). These results indicate that a red LED trap could be useful to control T. castaneum adults.

Growing evidence indicates a crucial role of the gut microbiota in physiological functions. Gut-brain axis imbalance has also been associated with neuropsychiatric and neurodegenerative disorders. Studies have suggested that probiotics regulate the stress response and alleviate mood-related symptoms. In this study, we investigated the effects of the probiotic Lacticaseibacillus rhamnosus IDCC3201 (L3201) on the behavioral response and fecal metabolite content in an unpredictable chronic mild stress (UCMS) mouse model. Our study shows that chronic stress in mice for three weeks resulted in significant changes in behavior, including lower locomotor activity, higher levels of anxiety, and depressive-like symptoms, compared to the control group. Metabolomic analysis demonstrated that disrupted fecal metabolites associated with aminoacyl-tRNA biosynthesis and valine, leucine, and isoleucine biosynthesis by UCMS were restored with the administration of L3201. Oral administration of the L3201 ameliorated the observed changes and improved the behavioral alterations along with fecal metabolites, suggesting that probiotics play a neuroprotective role.

Acupuncture has been used for the treatment and prevention of stress-related disorders. In the present study, the effect of electroacupuncture on the behavioral and biochemical responses to restraint stress was evaluated in rats. Sprague-Dawley male rats underwent to immobilization stress for 21 days (6 hours/day). Electroacupuncture (2 Hz, 2 mA, and 10 minutes) was applied either to the acupuncture point HT7 (Shenmen) or the nonacupuncture point in the tail for the last 7 days. Rats were randomly divided into four groups: the normal group (n=10, without the restraint stress), the stress group (n=10, with restraint stress), the HT7 group (n=10, with restraint stress and electroacupuncture to HT7), and the NA group (n=10, with restraint stress and electroacupuncture to the nonacupuncture point). The anxiety-related behavior was tested using the elevated plus maze and the Vogel test on day 22. The expression of tyrosine hydroxylase in the locus coeruleus was measured by immunohistochemistry. R maze and the Vogecreased the response of the anxiety-related behavior. The number of tyrosine hydroxylase-immunoreactive cells were also increased. The HT7 group showed a significant decrease of anxiety-related behavioral response, compared to the stress group. The tyrosine hydroxylase-immunoreactive expression was also decreased in the HT7 group. These findings suggestthat electroacupuncture to HT7 might play a role in reducing the stress-related responses, which may be helpful for the treatment of stress-related disorders.

Purpose : The purpose of this study was to investigate the differences in social quotient and sensory processing function between completed-toileting and incomplete-toileting children with autism spectrum disorder (ASD). We aims to provide a basis for the training of children with autism spectrum disorders. Methods : The subjects of this research were children with ASD, aged from 4 to 7, receiving sensory integration therapy at the H-Child Development Research Center in Busan, South Korea. After recruiting 30 parents who had children with ASD, we interviewed them and we divided their children into completed-toileting group and incomplete-toileting group based on the past researches. We assessed them using the Social Maturity Scale and Sensory Profile. Spearman correlation was used to analyze between the sensory processing score and social quotient. Mann-Whitney U test was used to compare the Sensory Profile scores of the two groups. Results : The social quotient was correlated with the sensory processing score in the most of component as for auditory processing, vestibular processing, touch processing, multisensory processing, orosensory processing, except for visual processing. The groups of completed-toileting and incomplete-toileting group showed statistically significant intergroup difference in sensory seeking, emotional reactive, oral-sensory sensitivity, and inattention/distractibility in the sensory factor region. No statistically significant difference from intergroup was observed in any modulation areas, nor in behavioral & emotional response domains. Conclusion : A significant intergroup difference was observed in the most of sensory processing areas, except for modulation areas and behavioral & emotional response domains. The result revealed that toileting is significantly correlated with sensory processing. Therefore, this study suggests that the sensory processing function should be considered in the toilet training of children with ASD.
