Temporal dynamics of intranasal oxytocin in human brain electrophysiology

Patricia Figueiredo, Janir Nuno Ramos Antunes Da Cruz

Oxytocin (OT) is a key modulator of human social cognition, popular in behavioral neuroscience. To adequately design and interpret intranasal OT (IN-OT) research, it is crucial to know for how long it affects human brain function once administered. However ...

Drugs Based on de novo-developed Peptides are Coming of Age

Christian Heinis, Kaycie Marie Butler

Naturally evolved peptides, such as the hormone oxytocin or the anti-bacterial vancomycin, have seen decades of success as powerful therapeutics due to many of the favorable properties of peptides. Not every desired target has a naturally occurring bioacti ...

The link between aberrant hypothalamic-pituitary-adrenal axis activity during development and the emergence of aggression-Animal studies

Maria del Carmen Sandi Perez, Damien Sébastien Huzard, Sophie Elizabeth Walker

Aggressive behavior is not uniform, including proactive and reactive forms of aggression. Aberrant functioning of the hypothalamic-pituitary-adrenal (HPA) axis is frequently associated with abnormal aggression. Here, we review the rodent literature in orde ...

Stress Impacts the Regulation Neuropeptides in the Rat Hippocampus and Prefrontal Cortex

Aurélie Lattion, Laura Lozano Montes

Adverse life experience increases the lifetime risk to several stress-related psychopathologies, such as anxiety or depressive–like symptom following stress in adulthood. However, the neurochemical modulations triggered by stress have not been fully charac ...

Converting disulfide bridges in native peptides to stable methylene thioacetals

Nicolai Cramer, Christopher Matthew Bandeli Kourra

Disulfide bridges play a crucial role in defining and rigidifying the three-dimensional structure of peptides. However, disulfides are inherently unstable in reducing environments. Consequently, the development of strategies aiming to circumvent these defi ...

A Preclinical Model for ERα-Positive Breast Cancer Points to the Epithelial Microenvironment as Determinant of Luminal Phenotype and Hormone Response

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Valentina Scabia, Rachel Marcone, Laura Battista, Valérian Charles Robert Dormoy

Seventy-five percent of breast cancers are estrogen receptor α positive (ER(+)). Research on these tumors is hampered by lack of adequate in vivo models; cell line xenografts require non-physiological hormone supplements, and patient-derived xenografts (PD ...

Development of Stapling Methods by Selective Side Chain Modifications of Bioactive Peptides

Christopher Matthew Bandeli Kourra

Cyclic peptide therapeutics fill the gap between small molecules (5000 Da) as a separate class of drugs, combining the advantages of both in terms of high selectivity, bioavailability, synthetic accessibility and low toxicity. Howe ...

Female vulnerability to the development of depression-like behavior in a rat model of intimate partner violence is related to anxious temperament, coping responses, and amygdala vasopressin receptor 1a expression

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Guillaume Poirier

Exposure to violence is traumatic and an important source of mental health disturbance, yet the factors associated with victimization remain incompletely understood. The aim of the present study was to investigate factors related to vulnerability to depres ...

ID4 regulates mammary gland development by suppressing p38MAPK activity

Yiming Li, Cathrin Brisken, Xiuwei Zhang, Jun Dong, Marian Caikovski

The ID family of helix-loop-helix proteins regulates cell proliferation and differentiation in many different developmental pathways, but the functions of ID4 in mammary development are unknown. We report that mouse Id4 is expressed in cap cells, basal cel ...

Evidence for a role of oxytocin receptors in the long-term establishment of dominance hierarchies

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Marjan Timmer

Exposure to stress can affect the establishment of dominance hierarchies. In our model, a social hierarchy established by two male rats during a first encounter is not maintained 1 week later. If one of the two rats is stressed, the stressed rat becomes su ...

Neurobiological Mechanisms Involved in the Establishment and Maintenance of Dominance Hierarchies and its Modulation by Stress in Rats

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can have a strong and long lasting effect on the establishment and maintenance of dominance hierarchies in rats. When two rats of a pair have not been stressed (non-stressed pair) before a first social encounter, they establish a dominance hierarchy ...

Serotonin, pregnancy and increased autism prevalence: Is there a link?

Nouchine Hadjikhani

The prevalence of autism, a neurodevelopmental condition resulting from genetic and environmental causes, has increased dramatically during the last decade. Among the potential environmental factors, hyperserotonemia during pregnancy and its effect on brai ...

Improving the Electrochemical Activity of LiMnPO4 Via Mn-Site Substitution

Michael Graetzel, Mingkui Wang, Nam Hee Kwon

HPL SA report the modification of the electrochemical performance of lithium manganese phosphate (LiMnPO4) via Mn-site bivalent substitution. Manganese (10%) is substituted with iron, nickel, magnesium, or zinc. These substituents are shown via an X-ray to ...
