RESUMO

Cushman argues that "rationalization is rational." We show that there is reasonable empirical clinical and forensic psychological evidence to support viewing rationalization as a quite suboptimal defense mechanism. Rationalization has been found to be associated not only with poorer emotional development, but also with a broad range of antisocial behavior, including not only shoplifting, but also pedophilia and murder.

RESUMO

In Neurospora and other fungi, the protein frequency (FRQ) is an integral part and a negative element in the fungal circadian oscillator. In Drosophila and many other higher organisms, the protein period (PER) is an integral part and a negative element of their circadian oscillator. Employing bioinformatic techniques, such as BLAST, CLUSTAL, and MEME (Multiple Em for Motif Elicitation), 11 regions (sequences) of potential similarity were found between the fungal FRQ and the Drosophila PER. Many of these FRQ regions are conserved in many fungal FRQ(s). Many of these PER regions are conserved in many insects. In addition, these regions are also of biological significance since mutations in these regions lead to changes in the circadian clock of Neurospora and Drosophila. Many of these regions of similarity between FRQ and PER are also conserved between the Drosophila PER and the mouse PER (mPER2). This suggests conserved and important regions for all 3 proteins and a common ancestor, possibly in those amoeba, such as Capsaspora, that sits at the base of the phylogenetic tree where fungi and animals diverged. Two additional examples of a possible common ancestor between Neurospora and Drosophila were found. One, the white collar (WC-1) protein of Neurospora and the Drosophila PER, shows significant similarity in its Per/Arnt/Sim (PAS) motifs to the PAS motif of an ARNT-like protein found in the amoeba, Capsaspora. Two, both of the positive elements in each system (i.e., WC-1 in Neurospora and cycle [CYC] in Drosophila), show significant similarity to this Capsaspora ARNT protein. A discussion of these findings centers on the long-time debate about the origins of the many different clock systems (i.e., independent evolution or common ancestor as well as to the question of how new genes are formed).

RESUMO

The fungal clock, especially that in Neurospora crassa, is composed of several proteins, notably FRQ, WC-1, and WC-2, which interact at the protein level and at the level of transcription. It is shown here that regions of the FRQ that are highly conserved in many fungal species show significant similarity to regions of proteins found in the amoebae Capsaspora and Acanthamoebae. These 2 amoebae were specifically explored because they have been suggested, based on extensive evidence, to be related to precursors of the modern fungi. Those proteins in Capsaspora/Acanthamoebae with some similarity to FRQ are LARP (an RNA-binding protein), ARNT (which has a PAS motif), and heat shock factor (HSF). These regions of LARP and HSF that show similarity to FRQ are highly conserved between plants, animals, and amoeba. This suggests that these regions were present at the time of the divergence of plants, fungi, insects, and animals, and therefore, they could be plausible precursors to regions of the fungal FRQ. These particular regions of FRQ that show similarity to LARP and HSF are also of functional significance since mutations in these regions of the Neurospora FRQ led to changes in the rhythm. The FRQ proteins from 13 different species of fungi were analyzed via motif analysis (MEME), and 11 different motifs were found. This provides some understanding as to the minimum requirements for an FRQ protein. Many of these FRQ motifs can be matched up with known domains in FRQ. In addition, these 13 different species of fungi were screened for the presence/absence of 7 additional genes/proteins that play some role in fungal clocks.

RESUMO

INTRODUCTION: The terminology for anorectal dysfunction in women has long been in need of a specific clinically-based Consensus Report. METHODS: This Report combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS), assisted on Committee by experts in their fields to form a Joint IUGA/ICS Working Group on Female Anorectal Terminology. Appropriate core clinical categories and sub classifications were developed to give an alphanumeric coding to each definition. An extensive process of twenty rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS: A Terminology Report for anorectal dysfunction, encompassing over 130 separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Female-specific anorectal investigations and imaging (ultrasound, radiology and MRI) has been included whilst appropriate figures have been included to supplement and help clarify the text. Interval review (5-10 years) is anticipated to keep the document updated and as widely acceptable as possible. CONCLUSION: A consensus-based Terminology Report for female anorectal dysfunction terminology has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

RESUMO

INTRODUCTION: Both erectile dysfunction (ED) and premature ejaculation (PE) impair the quality of sexual intercourse for both men and their female partners. AIMS: This study aims to examine with a large representative sample the interrelationships of measures of ED, PE, typical intravaginal ejaculatory latency time (IELT), men's perceived relationship quality with their mother, and age of first being in love. METHODS: In this cross-sectional study, a nationally representative sample of 960 Czech coitally experienced men (aged 15-84), provided age, International Index of Erectile Function 5-item (IIEF-5), Index of Premature Ejaculation (IPE) scores, IELT, rating of relationship with their mother, and age at first being in love. MAIN OUTCOME MEASURES: Correlations, partial correlations adjusting for age, analysis of covariance (ANCOVA), and multiple regression statistical methods were used. RESULTS: IIEF-5, IPE, and IELT were significantly intercorrelated (IIEF-5 and IPE: r=0.64). Better IIEF-5 scores were associated with younger age at first (and ever) being in love. Poorer IPE score, shorter IELT, and mild-moderate ED were associated with poorer perceived mother relationship (which was also associated with first being in love at an older age). Multiple regression analyses revealed that: (i) greater IELT was associated with better erectile function and better mother relationship, but not with age; and (ii) IELT of <1 minute was associated with poorer perceived mother relationship and poorer IIEF-5, but marginally with age. History of homosexual activity was unrelated to IIEF-5, IPE, IELT, and perceived mother relationship scores. CONCLUSIONS: The findings suggest that degrees of ED and PE are often comorbid, and both ED and PE are associated with less favorable early experiences with women. Brody S and Weiss P.

RESUMO

INTRODUCTION: Research indicated that (i) vaginal orgasm consistency is associated with indices of psychological, intimate relationship, and physiological functioning, and (ii) masturbation is adversely associated with some such measures. AIM: The aim of this study was to examine the association of various dyadic and masturbation behavior frequencies and percentage of female orgasms during these activities with: (i) measures of dyadic adjustment; (ii) sexual satisfaction; and (iii) compatibility perceived by both partners. METHODS: In a sample of 85 Czech long-term couples (aged 20-40; mean relationship length 5.4 years), both partners provided details of recent sexual behaviors and completed sexual satisfaction, Spanier dyadic adjustment, and Hurlbert sexual compatibility measures. Multiple regression analyses were used. MAIN OUTCOME MEASURE: The association of sexual behaviors with dyadic adjustment, sexual compatibility, and satisfaction was analyzed. RESULTS: In multivariate analyses, women's dyadic adjustment is independently predicted by greater vaginal orgasm consistency and lower frequency of women's masturbation. For both sexes, sexual compatibility was independently predicted by higher frequency of penile-vaginal intercourse and greater vaginal orgasm consistency. Women's sexual satisfaction score was significantly predicted by greater vaginal orgasm consistency, frequency of partner genital stimulation, and negatively with masturbation. Men's sexual satisfaction score was significantly predicted by greater intercourse frequency and any vaginal orgasm of their female partners. Concordance of partner vaginal orgasm consistency estimates was associated with greater dyadic adjustment. CONCLUSIONS: The findings suggest that specifically penile-vaginal intercourse frequency and vaginal orgasm consistency are associated with indices of greater intimate relationship adjustment, satisfaction, and compatibility of both partners, and that women's masturbation is independently inversely associated with measures of dyadic and personal function. Results are discussed in light of previous research and an evolutionary theory of vaginal orgasm.

RESUMO

OBJECTIVE: Given that adiposity is related to poorer female sexual function, among many other health problems, the present study aimed at testing the hypothesis that larger waist circumference, an index of subcutaneous and abdominal fat mass, is associated with lack of specifically vaginal orgasm. Study design One hundred and twenty Portuguese women of reproductive age had their waist measured and reported their past month frequency of penile-vaginal intercourse (PVI), vaginal orgasm, orgasm from clitoral masturbation during PVI, non-coital partnered sex (in the absence of same-day PVI), non-coital partnered sex orgasm (regardless of same-day PVI), masturbation, and masturbation orgasm. RESULTS: In both simple and partial correlations (controlling for age, social desirability responding, relationship status, and cohabitation status), larger waist circumference was associated with lack of any vaginal orgasm and with having masturbated in the past month. In a multiple regression, larger waist circumference was independently predicted by lesser frequency of vaginal orgasm, greater frequency of masturbation, and older age. CONCLUSION: Abdominal fat mass appears to be adversely associated with lesser capacity for vaginal orgasm, but not for orgasms from other sexual activities. Results are discussed in the context of vaginal orgasm being relatively more contingent on situations of increased fitness in both partners.

RESUMO

Immature psychological defense mechanisms are psychological processes that play an important role in suppressing emotional awareness and contribute to psychopathology. In addition, unhealthy food, television viewing, and alcohol consumption can be among the means to escape self-awareness. In contrast, engaging in, and responding fully to specifically penile-vaginal intercourse (PVI) is associated with indices of better emotional regulation, including less use of immature defense mechanisms. There was a lack of research on the association of immature defense mechanisms with personal importance of junk food, alcohol, television, PVI, and noncoital sex. In an online survey, 334 primarily Scottish women completed the Defense Style Questionnaire (DSQ-40), and rated the personal importance of junk food, alcohol, television, PVI, and noncoital sex. Immature defense mechanisms correlated with importance of junk food, alcohol, and television. Importance of PVI correlated with mature defenses, and less use of some component immature defenses. Importance of alcohol correlated with importance of junk food, television, and noncoital sex. Importance of junk food was correlated with importance of television and noncoital sex. The findings are discussed in terms of persons with poorer self-regulatory abilities having more interest in junk food, television, and alcohol, and less interest in PVI.

RESUMO

INTRODUCTION: Research indicated that: (i) vaginal orgasm (induced by penile-vaginal intercourse [PVI] without concurrent clitoral masturbation) consistency (vaginal orgasm consistency [VOC]; percentage of PVI occasions resulting in vaginal orgasm) is associated with mental attention to vaginal sensations during PVI, preference for a longer penis, and indices of psychological and physiological functioning, and (ii) clitoral, distal vaginal, and deep vaginal/cervical stimulation project via different peripheral nerves to different brain regions. AIMS: The aim of this study is to examine the association of VOC with: (i) sexual arousability perceived from deep vaginal stimulation (compared with middle and shallow vaginal stimulation and clitoral stimulation), and (ii) whether vaginal stimulation was present during the woman's first masturbation. METHODS: A sample of 75 Czech women (aged 18-36), provided details of recent VOC, site of genital stimulation during first masturbation, and their recent sexual arousability from the four genital sites. MAIN OUTCOME MEASURES: The association of VOC with: (i) sexual arousability perceived from the four genital sites and (ii) involvement of vaginal stimulation in first-ever masturbation. RESULTS: VOC was associated with greater sexual arousability from deep vaginal stimulation but not with sexual arousability from other genital sites. VOC was also associated with women's first masturbation incorporating (or being exclusively) vaginal stimulation. CONCLUSIONS: The findings suggest (i) stimulating the vagina during early life masturbation might indicate individual readiness for developing greater vaginal responsiveness, leading to adult greater VOC, and (ii) current sensitivity of deep vaginal and cervical regions is associated with VOC, which might be due to some combination of different neurophysiological projections of the deep regions and their greater responsiveness to penile stimulation.

RESUMO

INTRODUCTION: Sexual intercourse, orgasm, and sexual satisfaction are associated with well-being and improved quality of life. The pituitary hormone prolactin (PRL) may have an important role in regulating (and thus indexing) sexual satiety and satisfaction. AIM: Physiological indices to quantify the quality and resulting satisfaction from female orgasm would be valuable. Therefore we aim to validate associations of orgasm-induced PRL surges with women's orgasm quality and subsequent sexual satisfaction. METHODS: In a prospective study, with a pre-post, single-blinded, cross-over design in a naturalistic field setting, we analyzed the correlation of women's post-orgasmic serum PRL surges following sexual intercourse with women's perceived quality of orgasm and resulting sexual satisfaction, as measured by a questionnaire. MAIN OUTCOME MEASURES: PRL levels prior to and following penile-vaginal intercourse with and without orgasm, and scores from the Acute Sexual Experience Scale (ASES) on quality of orgasm and sexual satisfaction. RESULTS: An analysis of variance of the blood samples in nine women indicated large magnitude, significant effects of intercourse orgasm on PRL levels (P = 0.004, eta squared = 0.78), as well as an interaction with the effect of multiple orgasms (P = 0.008, eta squared = 0.80). PRL post/pre ratios and arithmetic difference correlated strongly with orgasm quality (r = 0.85, P = 0.016, and r = 0.69, P = 0.08) and sexual satisfaction (r = 0.75, P = 0.05 and r = 0.77, P = 0.045). CONCLUSION: Women's intercourse orgasm induced PRL surges are strongly related to the quality of orgasm and subsequent sexual satisfaction. This implies that post-orgasmic PRL surges are an objective index of orgasm and orgasm quality. PRL might be used in future studies on basic research as well as a treatment target in sexual disorders in women.

RESUMO

Previous research has indicated that men generally rate slimmer women as more sexually attractive, consistent with the increased morbidity risks associated with even mild abdominal adiposity. To assess the association of women's waist size with a more tangible measure of perceived sexual attractiveness (as well as reward value for both sexes), we examined the association of women's age and waist circumference with an index of men's erectile function (IIEF-5 scores), frequency of penile-vaginal intercourse (PVI), and sexual satisfaction in a representative sample of Czechs (699 men and 715 women) aged 35-65 years. Multivariate analyses indicated that better erectile function scores were independently associated with younger age of self and partner and women's slimmer waist. PVI frequency was independently associated with women's younger age and women's slimmer waist. Sexual satisfaction was independently associated with men's younger age and slimmer waist for both sexes. Better erectile function, greater PVI frequency, and greater sexual satisfaction were associated with women's slimmer waist, independently of both sexes' ages. Possible reasons for the waist effects were discussed, including women's abdominal body fat decreasing their own desire through neurohormonal mechanisms and decreasing their partner's desire through evolutionarily-related decreased sexual attractiveness.
