Orgasm coercion occurs when someone pressures a partner to orgasm by implying that not orgasming will have negative consequences. But what happens when the coerced partner refuses to go along with orgasm coercion? And how do perpetrators of orgasm coercion react? In the current study, we analysed 100 participants' (cisgender women, n = 66; cisgender men, n = 24; gender/sex minorities, n = 10) descriptions of refusing orgasm coercion during their most recent orgasm coercion encounter. We assessed how participants expressed refusals, perpetrators reacted to these refusals, and perpetrator reactions connected to relationship and psychological outcomes. Results showed that participants used a variety of refusal strategies that were positively- or negatively-valenced. Some perpetrators (31%) reacted in positive, understanding ways. However, most perpetrators (61%) reacted negatively or with more coercion when confronted. Of note, results suggested that whether perpetrators responded in positive vs. negative ways did not depend on participants' refusal strategies. We also found that positive perpetrator reactions were associated with positive relationship outcomes, but participants reported high negative psychological outcomes regardless of perpetrators' reactions. Findings support that perpetrators of orgasm coercion are not necessarily invested in partners' positive experiences and that orgasm coercion cannot be resolved through better communication.

Gender euphoria is an important experience and concept for many, especially transgender and/or nonbinary individuals, but has not received much attention from psychological and clinical research. In contrast to gender dysphoria, which originates in psychiatry, the term "gender euphoria" has been mobilized by some LGBTQ people to describe the powerfully positive emotions that can come from one's gender/sex. As such, researchers and clinicians may benefit from conceptual clarity as to what gender euphoria is and what kinds of experiences might result in gender euphoria. We aimed to better understand how trans community members and others conceptualize the term "gender euphoria," including its relationship to gender dysphoria, as well as the contexts and behaviors that elicit gender euphoria. We administered an online qualitative survey to participants (N = 47) of diverse sexualities and gender/sexes (including transgender, cisgender, and/or nonbinary participants) who had heard of or used the term "gender euphoria." Participants answered open-ended questions about where they had heard the term being used, how they would define gender euphoria and gender dysphoria, the relation between these terms, and their gender euphoric experiences. Analyses resulted in five themes: (1) gender euphoria describes a joyful feeling of rightness in one's gender/sex, (2) gender euphoric experiences can be external, internal, and/or social, (3) "gender euphoria" originated in and circulates in online and in-person gender/sex minority communities, (4) dysphoria describes a negative feeling of conflict between gender/sexed aspects of one's self, and (5) the relationship between euphoria and dysphoria is complex. These results can inform qualitative and quantitative research, gender affirmative clinical practice, political fights for transgender rights, and understandings of gendered experiences for people of all identities.

In pornography created for (and often by) heterosexual men, it is common for women performers to look directly at the camera. This simulates eye contact with viewers and is intended to create a participatory point of view. Little is known about the function of direct gaze in this context. In other domains, eye contact can increase physiological arousal, but also facilitate nurturant connection. Eye contact in porn may thus have a range of functions, which we explored in a preregistered study. Participants (N = 799) watched a brief sexually explicit video that had a high prevalence of eye contact (n = 399) or no eye contact (n = 400), then completed measures of eroticism, nurturance, guilt, other measures of affect and desire, participatory perspective, and whom they experienced sexual desire for. We found no significant differences in eroticism, nurturance, guilt, or other affect or desire measures across conditions, but found some evidence that eye contact may facilitate a participatory (vs. observational) perspective and desire for the performer in the film (e.g. vs. someone else), .05 < ps < .10. Overall, our findings provide preliminary insight into the function of eye contact in pornography and provide promising avenues for future research. [ABSTRACT FROM AUTHOR]

Sexuality research has generally privileged attractions based on partners’ sexed physical bodies over attractions based on other features, including gender expression and personality traits. Gender may actually be quite central to sexual attractions. However, its role has received little empirical attention. To explore how gendered and sexed features, among others, are related to sexual attractions, the current study assessed how sexually diverse individuals described their attractions to feminine, masculine, and gender-nonspecific features of women and men. A sample of 280 individuals responded to the open-ended questions: “What do you find attractive in a man?” and “What do you find attractive in a woman?” We coded responses as pertaining to physical and/or psychological features, and as being gendered masculine, feminine, or gender-nonspecific. Our analyses showed that participants named gender-nonspecific features most frequently in responses to both questions, feminine features more than masculine features in attractions to women, and masculine features more than feminine features in attractions to men. Additionally, participants named feminine physical features more than masculine physical features, and masculine psychological features more than feminine psychological features, both in their attractions to women and overall. These results highlight the importance of considering attractions based on gender, rather than sex alone. [ABSTRACT FROM AUTHOR]

In this article, a new computational approach is investigated to predict the crack propagation inside some smart structures equipped with surface-bonded piezoelectric layers; meanwhile, the electromechanical coupling is exploited. The current industrial need of analyzing rather irregular geometries motivates resorting to a numerical approach. Therefore, the finite element method (FEM) is used to predict both the fracture behavior and the coupled response of piezoelectric material through a suitable interoperation of the two computational environments, available in some commercial code like the ABAQUS©. The two solutions are then coupled by means of a subroutine, in this case operated through the ISIGHT©tool. After a preliminary analysis and a validation, results of some numerical simulations are shown to highlight some significant peculiarities of the coupled behavior of the piezoelectric material.

Orgasms have been promoted as symbols of sexual fulfillment for women, and have perhaps become the symbol of a woman's healthy sex life. However, some research has suggested that this focus on women's orgasms, though ostensibly for women, may actually serve men; but the mechanisms of this are unclear. In the present experiment, we hypothesized that women's orgasms specifically function as a masculinity achievement for men. To test this, we randomly assigned 810 men (M age = 25.44, SD = 8.31) to read a vignette where they imagined that an attractive woman either did or did not orgasm during a sexual encounter with them. Participants then rated their sexual esteem and the extent to which they would feel masculine after experiencing the given situation. Our results showed that men felt more masculine and reported higher sexual esteem when they imagined that a woman orgasmed during sexual encounters with them, and that this effect was exacerbated for men with high masculine gender role stress. These results suggest that women's orgasms do function--at least in part--as a masculinity achievement for men. [ABSTRACT FROM AUTHOR]

1. The aim of this study was to evaluate various levels ofSatureja khuzistanicaessential oil (SKEO) on performance and physiological parameters of broilers fed on wheat- or maize-based diets. 2. Treatments consisted of two cereals (maize- or wheat-based diets) and three levels of SKEO)0, 250 and 500 mg/kg). 3. Feed intake (FI) and body weight gain (BWG) decreased in broilers fed on the wheat-based diets compared to the control diet. Dietary supplementation of 500 mg/kg SKEO increased FI and BWG. Dietary SKEO supplementation was effective in improving FI and BWG only in wheat-based diets and was effective in improving feed conversion ratio (FCR) in both diets. 4. Dietary supplementation of 500 mg/kg SKEO caused a significant decrease in plasma cholesterol and triglycerides. Also, plasma low-density lipoprotein concentration was decreased in broilers fed on 250 and 500 mg/kg of SKEO. Plasma cholesterol levels in birds fed on the wheat-based diets were lower than in those fed on maize-based diets. 5. Dietary supplementation of 500 mg/kg SKEO increased caecal population ofLactobacillusand reduced total bacterial andEscherichia colicount. Caecal population ofLactobacillusdecreased in broilers fed on the wheat-based diets. 6. Digesta viscosity was increased in broilers fed on the wheat-based diets and decreased in broilers fed on 500 mg/kg SKEO compared to the control diet. Dietary SKEO supplementation was effective in reducing digesta viscosity values only in wheat-based diets. 7. Villus height of the duodenum and jejunum decreased in broilers fed on the wheat-based diets. Dietary supplementation of 500 mg/kg SKEO increased villus height and villus height-to-crypt depth ratios and decreased crypt depth of the duodenum compared to the control diet. 8. It can be concluded that dietary SKEO supplementation was effective in improving FI, BWG and FCR values in wheat-based diets. [ABSTRACT FROM AUTHOR]

Science reflects cultural practices and also occurs within them, and this ‘knowledge-culture’ is constituted by the public imaginary (general understandings and perceptions of phenomena) and the ‘scientific imaginary’ (the ability to envision scientific questions, methods, meanings and material possibilities for studying phenomena). In this feminist science laboratory case study, I argue that nomenclature contributes to epistemologies of ignorance, delimiting knowledge-culture and the scientific imaginary about vaginal fluid, which has implications for understandings of women’s bodies as well as sexual health potentials. Abject terms for vaginal fluid (vaginal mucous; vaginal discharge) preclude its existence in the scientific imaginary except as passive signs of dis-ease. I argue for a gendered abjectness of vaginal fluid’s names by situating it next to fluids that are tied to other mucosal surfaces, thus showing that even when gender is not involved in the name, gendered knowledge-culture can still affect science. I discuss how my ongoing lab research in social neuroendocrinology attends to the immune properties of vaginal fluid and positions women’s bodies as agentic, taking seriously the promise that ‘vaginal fluid’ might afford.

The metabolic syndrome (MetS) is associated with elevated risk of diabetes and cardiovascular morbidity. However, little is known of the sensitivity, specificity and predictive value of individual criteria in patients with schizophrenia. We studied the prevalence of MetS using the International Diabetes Federation (IDF) and adapted National Cholesterol Education Program (NCEP-ATPIII) criteria in the Northern Finland 1966 Birth Cohort population. In addition, the sensitivity, specificity and predictive values for individual criteria were determined. Both adapted NCEP-ATPIII and IDF criteria for MetS identified the same cases (29% of all schizophrenia patients). Among the IDF criteria, hypertriglyceridemia had the highest sensitivity, correctly identifying 77.8% of the patients. Reduced HDL cholesterol was the most specific criteria, with 95% specificity equalling a positive likelihood ratio of 9.78. Thus both the IDF and NCEP-ATPIII criteria may be equally useful in identifying MetS. [ABSTRACT FROM AUTHOR]

Definition of both quality and quantity of energy consumption of crops by recently developed remote sensing methods has been an important factor in the control of sustainable bioenergy production in terms of food security. This study was conducted to find the critical physiological stages of orange trees from their energy supply and energy balances using remote sensing methods. The relationships between absorbed photosynthetically active radiation (APAR) and chlorophyll content (chl) of the leaves at different growth stages were investigated. Canopy reflectance by hand-held spectroradiometer and total chl analysis at the laboratory were measured simultaneously from the random samples taken from tour different parts of orange trees in orchards, each orchard being at a different age group. Reflectance measurements were conducted between 450 nm and 900 nm wavelength at tour different bands (three visible bands and one near-infrared band) at the four basic physiological periods of orange trees. Reflectance values measured in the field were converted to APAR (W m-2) and the chl values were determined in mg ml-1. According to the statistical analysis, there was a strong relationship between APAR at the bands of 450-520 nm (blue) and 630-690 nm (red) and the chlorophyll content (p ⩽ 0.01; R² = 0.750 at blue wavelength and R² = 0.770 at red wavelength) in June (fruit setting stage). These results showed that the relationships between chl and APAR values were very strong despite low levels of APAR at this stage, in comparison to the other ones. Amongst all the stages. APAR values were the highest in November. Another important result was that Washington navel trees unexpectedly had the highest APAR during the dormancy stage. These results suggested that the relationships between PAR utilization and chlorophyll content were important for tree health and indirect yield of per annum plants such as citrus. The values obtained from the leaves of orange trees at different physiological periods were more important than those relationships for the trees of different ages. [ABSTRACT FROM AUTHOR]

Background: A chronic HBsAg carrier state, a major cause of viral spread in a community, is one of the consequences of hepatitis B virus (HBV) infection. Although successful immunization programs have been initiated to eliminate the virus, there is still a large number of people with HBV infection worldwide. This study was designed to investigate the effect of indomethacin treatment on HBV markers in humans, in comparison with a control group. Methods: In total, 65 chronic `healthy' HBV carriers were involved in the study. Patients were divided randomly into two groups. Group I (n = 42) received oral indomethacin 75 mg daily for 6 months. Group II (n = 23) acted as control. Patients in both groups were followed up for 6 months, during which laboratory tests, including viral parameters, were performed periodically. Liver biopsy was done in 17 patients (11/42 of the indomethacin group and 6/23 of the control group). Results: All liver biopsies showed grade 0-2 and stage 0-1 HBV in both groups (P > 0.05). HBsAg positivity did not change in any patient in either group. Five patients who had positive HBeAg in group I became negative 4 months later, while patients in group II continued to be positive at 6 months (P < 0.001). Similarly, all patients receiving indomethacin exhibited a total anti-HBeAg immunoglobulin response at 6 months, while the control group remained the same during this period (P < 0.05). HBV DNA, as detected by polymerase chain reaction in 20/22 (91%), was negative in group I at the end of 6 months. No change was observed in group II (P = 0.007). Conclusions: Although no biochemical analyses were performed on prostaglandins in the present study, the results suggest that the prostaglandin pathway may be involved in the pathogenesis of the immune response against HBV, and that the suppression of viral replication is achieved as indicated by the disappearance of HBeAg and HBV DNA in healthy chronic HBV carriers.

Background: Acidic beverages may be involved in regulating the cell proliferation of the gastric mucosa. We therefore analyzed the interaction of Coca-Cola consumption and gastric mucosal proliferation by means of flow cytometry. Methods: Sixteen healthy students agreed to participate in this study. All volunteers underwent an oesophagogastroduodenoscopy after a 12-h overnight fast. Endoscopic changes in the gastric mucosa were determined quantitatively. One day later, after a 12-h overnight fast, all volunteers received standard Coca-Cola (200 ml, pH 2.6, 4°C). One hour later all volunteers again underwent oesophagogastroduodenoscopy, to measure gastric mucosal damage. During both the first and the second endoscopy at least four biopsy specimens were taken from the antrum for flow cytometric analysis. Results: The endoscopic analysis showed that there was no difference before and after Coca-Cola consumption. However, the flow cytometric analysis showed that Coca-Cola inhibited the proliferation index and the S phase. Before Coca-Cola consumption G0/G1: 60 (57-62), G2/M: 0.6 (0.2-1), S: 40 (37-42), and PI: 0.40 (0.38-0.43) and after Coca-Cola consumption G0/G1: 70 (60-73), G2/M: 1.9 (1.2-2.5), S: 28 (26-32), and PI: 0.30 (0.27-0.34) the cell population G0/G1 and G2/M phases were significantly increased (P < 0.0001, 0.0003), and the cell population S and PI phases were significantly low compared with the pre-consumption data (P < 0.0002, 0.0001). Conclusion: The cell cycle analysis reflects that Coca-Cola inhibits a crucial event in the cell cycle occurring at the G1/S border. [ABSTRACT FROM AUTHOR]
