Introduction: Stimulating either endogenous cannabinoids or opioids within a restricted dorsomedial "hedonic hotspot" in nucleus accumbens (NAc) shell enhances hedonic impact, or "liking" reactions to sweet tastes. In this study, we probed within this hotspot the relationship between endocannabinoid and opioid signals in hedonic enhancement. Materials and Methods: Specifically, we asked whether enhancement of sucrose "liking" by intra-NAc microinjections of the endocannabinoid anandamide requires concurrent endogenous opioid signaling. Results: Co-administration of the opioid antagonist naloxone in the same NAc microinjections with anandamide prevented the endocannabinoid from enhancing orofacial "liking" reactions to sucrose. Since intra-NAc hotspot naloxone injection alone failed to affect hedonics, reversal of anandamide-induced "liking" by opioid blockade reveals an interdependence of opioid and cannabinoid signaling in enhancing taste hedonic impact. Conclusions: These results elaborate our understanding of the mechanisms of hedonic processing of food rewards, and may also carry implications more generally for how opioid and cannabinoid drugs interact to generate natural pleasures, or drug-induced euphoria.

OBJECTIVE: The aim of this study is to assess whether the touch of osteopathic manipulative treatment (OMT) can affect the endogenous production of oxytocin in fullterm pregnant women and the assessment of well-being following the treatment. PATIENTS AND METHODS: In this study have been enrolled 57 pregnant women at full-term pregnancy (37th-41st week) for evaluation of the concentration of salivary oxytocin 2 minutes before and 2 minutes after a single session of OMT by an osteopath lasting for 30 minutes. Pre-OMT and post-OMT saliva samples were collected with the use of Salivette® salivary swabs. 7 salivary swabs were excluded from the analysis. 50 samples were analyzed with an appropriate ELISA kit. RESULTS: The mean OT salivary concentration pre-OMT was 89.98±16.39, and post-OMT was 100.60±19.13 tends to increase with p=0.0000051. In multivariate analysis, two subgroups show interesting data in the mean difference in OT salivary concentration post-OMT: women with painful contractions (p=0.06) and women under 35 years (p=0.09). CONCLUSIONS: The results of this study demonstrate that the effectiveness of OMT-increasing endogenous oxytocin is statistically significant in full-term pregnant women. The sensation of well-being found in most women indicates that there has been a predominantly central rather than peripheral oxytocin release after OMT. [ABSTRACT FROM AUTHOR]

In response to the national conversation about the U.S.-Mexico border and immigration in recent years, we created an online partnership between students in concurrent border studies courses at our two campuses: a public Hispanic-serving institution in South Texas and a private, small liberal arts college in Michigan. We explored whether and how the tensions between privileged and disadvantaged students documented in the traditional classroom would manifest online, and how we could use virtual technologies most effectively to structure transformative learning, defined as recognition and articulation of the structural and cultural systems that frame individual experience and meaning-making, across difference. As we document in this essay, tensions around racial, class, and educational inequality did occur in our partnership. Yet these tensions were crucial in creating the conditions for transformative learning because they generated "disorienting dilemmas" that challenged students' assumptions and knowledge. Our intentional integration of critical multiculturalist curriculum and pedagogical practices (especially embodied, facilitated online interactions) capitalized upon those conditions. By the end of the partnership, both groups of students experienced significant--but distinctive--trajectories of transformative learning that unsettled not only their individual understandings, but also the dynamics of power that characterize the higher education landscape. Given the polarization wrought by border and immigration discourse and educational policies that will likely produce increasingly segregated campuses in years to come, such online partnerships show promise for critical multiculturalist educators seeking to create opportunities for learning across difference and inequality.

OBJECTIVE: Laparoscopic surgery offers many advantages compared to invasive surgery but one of the main problems is postoperative pain, partially resulting from the peritoneal inflammatory process mediated by inflammatory cytokines. The rationale of this study is that intraperitoneal washing could remove inflammatory mediators that are the cause of postoperative pain and could help in the removal of CO2 from the abdominal cavity. This article aims to analyze the effects of peritoneal lavage in the reduction of postoperative shoulder pain. PATIENTS AND METHODS: 277 patients enrolled to undergo laparoscopic gynecologic surgery were included in the study. Women are randomized into two groups, according to the use or non-use of peritoneal lavage with saline solution at the end of laparoscopic gynecological major procedures. RESULTS: Data show that the peritoneal lavage can significantly reduce postoperative pain in the first 36 hours after surgery, as well as patients’ requests for analgesics: during the first 3 postoperative days, requests for paracetamol were lower in the YW (Yes Washing) group than the NW (No Washing) group (77 vs. 101; p<0.05); similar results are obtained considering ketorolac administration (62 vs. 71; p<0.05). CONCLUSIONS: Peritoneal lavage after gynecological laparoscopic procedures may be effective in the reduction of postoperative pain and use of analgesics. [ABSTRACT FROM AUTHOR]

Giuseppe Lo Monte, Angela Graziano, Isabella Piva, Roberto Marci Department of Morphology, Surgery, and Experimental Medicine, University of Ferrara, Ferrara, Italy Abstract: For years, phosphodiesterase type 5 inhibitors have been used for the treatment of erectile dysfunctions. Due to the similarities between male and female sexual response, several studies have assessed the effects of sildenafil citrate (Viagra®) in women affected by female sexual arousal disorder. The results are still conflicting and the drug is not devoid of adverse effects. Furthermore, female sexual arousal disorder is a heterogeneous condition whose underlying causes are difficult to diagnose and appropriate treatment requires a thorough sexual, psychological, and medical history along with specialist consultations. The clinician should pursue a global approach to the patient with sexual difficulties, while non-hormonal treatment such as phosphodiesterase type 5 inhibitors (ie, sildenafil citrate) should be kept as the last option. Keywords: phosphodiesterase type 5 inhibitors, female sexual arousal disorder (FSAD), sildenafil citrate

The management of symptomatic fibroids has traditionally been surgical; however, alternative pharmacological approaches have been proposed to control symptoms. To date, gonadotropin-releasing hormone analogs are the only available drugs for the preoperative treatment of fibroids. However, the US Food and Drug Administration recently authorized ulipristal acetate (UPA), an oral selective progesterone-receptor modulator, for the same indication. UPA is a new, effective, and well-tolerated option for the preoperative treatment of moderate and severe symptoms of uterine fibroids in women of reproductive age. According to clinical data, UPA shows several advantages: it is faster than leuprolide in reducing the fibroid-associated bleeding, it significantly improves hemoglobin and hematocrit levels in anemic patients, and it grants a significant reduction in the size of fibroids, which lasts for at least 6 months after the end of the treatment. Furthermore, UPA displays a better tolerability profile when compared to leuprolide; in fact, it keeps estradiol levels at mid follicular phase range, thereby reducing the incidence of hot flushes and exerting no impact on bone turnover. On the grounds of this evidence, the administration of 5 mg/day ulipristal acetate for 3 months is suggested for different patient categories and allows for planning a treatment strategy tailored to meet an individual patient's needs.

Patssi Valdez, one of the most influential yet understudied female artists of the Chicana/o movement, was the only original and long-term female member of the 1970s art collective Asco. Through the visual discourses of pachuca glamour and punk, Valdez negotiated and exploited the gendered ideologies that visually put her at the center of the group. She used self-fashioning, or the intersection of dress with bodily performance, to respond to gendered ideologies of domesticity and a racialized public/private sphere that she confronted as a working-class Chicana in the 1960s and 1970s. Members of Asco were drawn together not only by their mutual interest in visual art and performance but also by a shared sensibility in fashion and dress; it was the sense of each of them becoming a work of art that led the group to extend their work into performance. Yet since fashion is often considered a superficial activity carried out by women and pitted against the serious male world of ideas, it has often been undervalued as a strategy of contestation. This essay closely reads two Asco performances, "Instant Mural" and "A La Mode," to center fashion as an active and crucial element of the group's public discourse and as a site of political negotiation and critique for Valdez.

We assessed the benefits of employing microthemes--short in-class writing assignments designed to facilitate active learning--as pedagogical tools in psychology courses. Students in target course sections completed 10 in-class microthemes during a semester. We designed the microthemes to serve as active learning assignments that would enhance student learning and long-term retention, as well as strengthen students' writing skills. The instructors provided feedback to students on the content and writing quality of each microtheme. Students reported that the microthemes were effective and engaging learning tools. A comparison of essay and multiple-choice scores for students in target versus control course sections suggested the effectiveness of the microthemes for student learning, retention, and writing development.
