Sexual desire includes complex motivation and drive. In the context of biological and cognitive-emotive state art of science, it is often a neglected field in medicine. With regard to the treatment, study on women's sexual function received less attention compared to the men's sexuality. In the past, this endeavor was relatively not well disseminated in the scientific community. Recently, there was a revolutionized surge of drug targets available to treat women with low sexual desire. It is timely to review the relevant biological approach, especially in the context of pharmacotherapy to understand this interesting clinical entity which was modulated by numerous interactive psychosocial inter-play and factors...

One of the crucial purposes of treating alcohol-dependent patients is to enhance their ability to stay abstinent after detoxification therapy. Anxiety and stress vulnerability are the main factors provoking alcohol craving and relapse. In the first months of abstinence, alcohol-dependent patients frequently show sleep disturbances, irritability and depression, indicating chronic activation of stress pathways. In addition, the loss of confidence in interpersonal interactions results in social withdrawal and reduced willingness to participate in therapeutic programs...

It is widely hypothesized that menstrual pain is triggered by prostaglandin synthesis that evokes high-pressure uterine contractions and ischemia. However, the effects of molecules implicated in menstrual pain on uterine contractility, perfusion, and oxygenation in vivo have been rarely demonstrated. Studies in women that do not respond to nonsteroidal anti-inflammatory drugs (NSAIDs) have reported elevated levels of platelet-activating factor (PAF). To establish in vivo evidence of PAF's capability to impair uterine homeostasis and to elicit visceral pain, we examined the effects of the PAF receptor agonist (carbamyl PAF [CPAF]) in comparison to other molecules hypothesized to play a role in uterine pain in mice...

BACKGROUND: Current neuroimaging perspectives on a variety of mental disorders emphasize dysfunction of the amygdala. The neuropeptide oxytocin (OXT), a key mediator in the regulation of social cognition and behavior, accumulates in cerebrospinal fluid after intranasal administration in macaques and humans and modulates amygdala reactivity in both species. However, the translation of neuromodulatory OXT effects to novel treatment approaches is hampered by the absence of studies defining the most effective dose and dose-response latency for targeting the amygdala...

The present study evaluated the self-report version of the Inventory of Callous-Unemotional Traits (ICU-SR) in terms of reliability, concurrent validity, and correlation with salivary oxytocin levels, a potential biomarker of CU traits. 67 socially at-risk male adolescents (mean 16.2 years) completed the ICU-SR, ICU teacher-version (ICU-TR), Strengths and Difficulties Questionnaire, and their medical files were coded for previous antisocial acts using Brown-Goodwin Lifetime Aggression Scale. Salivary samples were assayed for oxytocin...

The oxytocin system has recently received increasing attention due to its effect on complex human behaviours. In parallel to this, over the past couple of decades, the human-analogue social behaviour of dogs has been intensively studied. Combining these two lines of research (e.g. studying the relationship between dog social behaviour and the oxytocin system) is a promising new research area. The present paper reviews the existing literature on how oxytocin is related to different aspects of human-directed social behaviour in dogs...

This study evaluated the effect of Yucca schidigera (YS) extract on the physiological, reproductive, and endocrine indexes of New Zealand White rabbit does. Six-week-old rabbit does were fed a standard diet (control group) or a diet enriched with 5 or 20g of Y powder extract per 100-kg feed mixture for 350days. The does were artificially inseminated after induction of superovulation. Weight gain; conception and kindling rate; viability of pups and mothers; histopathological state of liver and muscle; plasma levels of progesterone (P4), oxytocin (OT), and prostaglandin F (PGF); and the release of P4, insulin-like growth factor I (IGF-I), OT, and PGF by isolated ovarian fragments and their response to the addition of benzene were analyzed...

Although the specialized literature on the etiology of alexithymia is controversial, neurobiological research has shown relevant advances. The aim of this review is to analyze the available evidence regarding the neurophysiological bases of alexithymia. A comprehensive review of available articles from Medline/PubMed, EBSCO and SciELO was conducted. Previously, alexithymia was linked to a reduced interhemispheric brain connection. From a childhood traumatic perspective, the right prefrontal cortex and the default mode network would experience alterations, first hypermetabolic (dopaminergic and glutamatergic dysregulation) and then hypometabolic-dissociative (serotonergic and opioid dysregulation), resulting in a distorted interoceptive and emotional awareness...

PURPOSE: Although perioperative hypothermia may increase maternal morbidity, active warming is infrequently performed to maintain normothermia during Cesarean delivery (CD). The aim of this prospective observational study was to determine the factors associated with maternal hypothermia in this setting. METHODS: Women scheduled for elective or emergency CD were consecutively included in this study from November 2014 to October 2015. Maternal temperature was measured using an infrared tympanic thermometer on the patient's arrival in the operating room, at skin incision, and at the end of skin suture...

BACKGROUND: Alcohol use disorders are associated with dysfunctional social relationships and stress responses. The neuropeptides oxytocin (OT) and vasopressin (AVP) are known to orchestrate or mediate many aspects of social behavior, stress responses, and ingestive behaviors. Because of the overlap between the effects of alcohol and the roles of oxytocin and vasopressin, we sought to determine if alcohol consumption altered expression of OT and AVP in the paraventricular nucleus of the hypothalamus (PVN), one of the key sites for OT and AVP synthesis...

During cancer chemotherapy, drugs such as 5-HT3 receptor antagonists have typically been used to control vomiting and anorexia. We examined the effects of oxytocin (OXT), which has been linked to appetite, on cisplatin-induced anorexia in rats. Fos-like immunoreactivity (Fos-LI) expressed in the supraoptic nucleus (SON), the paraventricular nucleus (PVN), the area postrema and the nucleus of the solitary tract (NTS) after intraperitoneal (ip) administration of cisplatin. We also examined the fluorescence intensity of OXT-mRFP1 after ip administration of cisplatin in OXT-mRFP1 transgenic rats...

Viruses are intracellular obligate parasites and the host cellular machinery is usually recruited for their replication. Human eukaryotic translation initiation factor 3 (eIF3) could be directly recruited by the hepatitis C virus (HCV) internal ribosome entry site (IRES) to promote the translation of viral proteins. In this study, we establish a fluorescence polarization (FP) based high throughput screening (HTS) system targeting the interaction between HCV IRES and eIF3. By screening a total of 894 compounds with this HTS system, two compounds (Mucl39526 and NP39) are found to disturb the interaction between HCV IRES and eIF3...

Oxytocin is increasingly studied for its therapeutic potential in psychiatric disorders which are associated with the deregulation of several neurotransmission systems. Studies in rodents demonstrated that the interaction between oxytocin (OT) and serotonin (5-HT) is critical for several aspects of social behavior. Using PET-scan in humans we have recently found that 5-HT 1A receptor (5-HT1AR) function is modified after intra-nasal oxytocin intake. However, the underlying mechanism between OT and 5-HT remains unclear...

When animals and their offspring are threatened, parents switch from self-defense to offspring protection. How self-defense is suppressed remains elusive. We postulated that suppression of the self-defense response, freezing, is gated via oxytocin acting in the centro-lateral amygdala (CeL). We found that rat dams conditioned to fear an odor, froze when tested alone, whereas if pups were present, they remained in close contact with them or targeted the threat. Furthermore, blocking oxytocin signaling in the CeL prevented the suppression of maternal freezing...

Social anxiety is one of the most commonly reported mental health problems among adolescents, and it has been suggested that parenting style influences an adolescent's level of anxiety. A context-dependent effect of oxytocin on human social behavior has been proposed; however, research on the oxytocin gene (OXT) has mostly been reported without considering contextual factors. This study investigated the interactions between parenting style and polymorphic variations in the OXT gene in association with social anxiety symptoms in a community sample of adolescents (n = 1,359)...

The study aimed to evaluate oxytocin (Oxt) serum levels before and after sexual intercourse in women affected by anorgasmia. The sample was constituted of 15 anorgasmic women and 16 orgasmic women. The Female Sexual Function Index (FSFI, cutoff ≤26.55) and the Female Sexual Distress Scale (FSDS, cutoff ≥15) questionnaires were used to assess sexual function and sexual distress, respectively. Serum Oxt levels were measured before sexual intercourse (T0) and 5 min after coital sexual activity (T1). Anorgasmic women had an unpleasant sexual experience (FSFI total score, 20...
