Top-down, auditory pallial regulation of the social behavior network by Jeremy A Spool

Social encounters rely on sensory cues that carry nuanced information to guide social decision-making. While high-level features of social signals are processed in the telencephalic pallium, nuclei controlling social behaviors, called the social behavior network (SBN), reside mainly in the diencephalon. Although it is well known how mammalian olfactory pallium interfaces with the SBN, there…

Characterization of serum and tissue oxytocinase and tissue oxytocin in the pregnant and non-pregnant mare by Mariana Diel de Amorim

Oxytocin is a hormone with functions in: reproduction, maternal bonding, milk ejection, and feeding/social behavior, and is reported to be present in a variety of tissues. Our goal is to characterize oxytocin and leucyl and cystinyl aminopeptidase (LNPEP/oxytocinase), a key regulator of oxytocin in mares. We measured serum and tissue LNPEP by ELISA from ovulation…

Diet-Induced Glial Insulin Resistance Impairs The Clearance Of Neuronal Debris by Mroj Alassaf

Obesity significantly increases the risk of developing neurodegenerative disorders, yet the precise mechanisms underlying this connection remain unclear. Defects in glial phagocytic function are a key feature of neurodegenerative disorders, as delayed clearance of neuronal debris can result in inflammation, neuronal death, and poor nervous system recovery. Mounting evidence indicates that glial function can affect…

Comparative genomics analysis of three conserved plasmid families in the Western Hemisphere soft tick-borne relapsing fever borreliae provides insight into variation in genome structure and antigenic variation systems by Alexander R Kneubehl

Borrelia spirochetes, causative agents of Lyme disease and relapsing fever (RF), have a uniquely complex genome consisting of a linear chromosome and circular and linear plasmids. The plasmids harbor genes important for the vector-host life cycle of these tick-borne bacteria. The role of Lyme disease causing Borrelia plasmids is more refined compared to RF spirochetes…

Overview of microplastic pollution and its influence on the health of organisms by Yingling Deng

Microplastic pollution has gradually become a major global concern, due to the widespread use of plastics. Microplastics enter the environment and are degradated, while also being ingested by organisms, affecting various physiological functions and adversely affecting the health of organisms. Microplastic pollution is currently a wide concern, but data on the impact on organisms is…

Does perceived support moderate the link between acculturative stress and problematic eating behaviors? The role of family, significant other, and friend support by Peiyi Wang

OBJECTIVE: Acculturative stress, often experienced by members of minority groups, is related to problematic eating behaviors. What remains poorly understood is the function of perceived social support in this link. This study evaluated the moderating role of perceived support from family, the significant other, and friends in the association between acculturative stress and problematic eating…

Predictors of Food and Physical Activity Tracking Among Young Adults by Erin K O’Loughlin

CONCLUSION: Food and PA tracking are relatively common among young adults. If the associations observed herein between compensatory behavior after overeating and tracking (among other observed associations) are replicated and found to be causal, caution may need to be exercised in making “blanket” recommendations to track food intake and/or PA to all young adults seeking…

Behaviors Associated With Household Transmission of SARS-CoV-2 in California and Colorado, January 2021-April 2021 by Apophia Namageyo-Funa

CONCLUSIONS: Sleeping in the same bedroom as the primary case and eating food prepared by the primary case were associated with secondary transmission. Household dimension and relationship to the primary case were associated with these behaviors. Our findings encourage innovative means to promote adherence to mitigation measures that reduce household transmission.

The clinical and sleep manifestations in children with FOXG1 syndrome by Lee-Chin Wong

FOXG1 syndrome is a rare neurodevelopmental disorder associated with severe cognitive dysfunction, autistic behavior, and early-onset hyperkinetic movement disorders. Patients have also been reported to experience sleep disturbances. However, these findings are mainly based on subjective caregivers’ reports, and limited by small case numbers. Moreover, no studies using objective evaluation tools, such as actigraphy, have…

Portion-control tableware differentially impacts eating behaviour in women with and without overweight by M A Vargas-Alvarez

Portion control tableware has been described as a potentially effective approach for weight management, however the mechanisms by which these tools work remain unknown. We explored the processes by which a portion control (calibrated) plate with visual stimuli for starch, protein and vegetable amounts modulates food intake, satiety and meal eating behaviour. Sixty-five women (34…
