“…as the level of anxiety increased, sexual desire decreased in both men and women (Montesi et al, 2013). Other studies have also demonstrated a significant relationship between mental health and sexual dysfunction (Berek, 2012;Lin, Juang, Wen, Liu, & Hung, 2012;Kalmbach, Pillai, Kingsberg, & Ciesla, 2015). This was in agreement with the findings of the current work.…”

Background: Sexual behavior is among the complex dimensions of humans. Various factors are effective in sexual function. Sexual dysfunction affects people's mental health. Objectives:The present study aims to determine the relationship between general health indices and sexual dysfunction among the women referring to Shiraz Forensic Medicine Center, Iran. Methods:This cross-sectional, descriptive-analytical study was conducted on 197 women experiencing spousal abuse who had referred to Shiraz Forensic Medicine Center in 2014. The data were collected using demographic information questionnaire, a questionnaire assessing violence against women, general health questionnaire (GHQ-28), and female sexual function index (FSFI). The data were entered into SPSS statistical software and analyzed using t-test, Chi-square test, Pearson's correlation coefficient, and regression analysis.Results: Based on the results, 91.9% of the participants had sexual dysfunction and 85.3% had mental disorders. Besides, a significant relationship was found between sexual dysfunction and somatic symptoms (P=0.027), anxiety and insomnia (P=0.004), as well as overall general health (P=0.041). Also, the results of Pearson's correlation test revealed significant associations between various dimensions of sexual dysfunction and general health. Conclusion:According to the results, physical and mental health seems to play a critical role in determining sexual dysfunction. Thus, the identification and treatment of physical and mental disorders are recommended for the patients suffering from sexual dysfunction.

“…In sexual desire and arousal disorder, while enjoying complete physical health, the person is not interested in sexual behavior and partnership (Berek, 2012;Hopkins et al, 2015). Sexual excitement disorder emerges with reduced vaginal wetness or dyspareunia.…”

“…Bonded groups may collapse in the presence of an efficient nonsolvent for alkanes, for example water. However, our recent measurements with dextrans and water/methanol eluents36 have shown that changes in the C‐18 phase volume are not significant up to a water content as high as 90%. Exclusion processes may be therefore considered similar or even identical for a given alkane bonded phase, irrespective of the eluent used.…”

Summary: Two kinds of retention mechanisms of polystyrene (PS) macromolecules are considered in liquid chromatography (LC) applying alkane-bonded silica gel phases as column packings. They are based on non-polar interactions between polymer segments and alkane groups, which lead to adsorption of polymer species on the surface situated between bonded alkane groups and eluent on the one hand (interphase adsorption) and to partition of macromolecules between bonded phase volume and eluent (enthalpic partition) on the other hand. The roles of both retention mechanisms were assessed for PS species with different molar masses and several series of binary eluents. Bare silica and C-1, C-4, C-8, as well as C-18-bonded phases were compared. The results demonstrated that the eluent had to be a thermodynamically poor solvent for macromolecules to push them onto/into the bonded phase. However, no quantitative dependence between the eluent's thermodynamic quality for macromolecules and the extent of retention of polymer species was found. Similarly, no correlation was identified between eluent quality and prevailing retention mechanism -either interphase adsorption on the trimethylsilylated silica gel or interphase adsorption plus enthalpic partition in the case of C-4, C-8 and C-18-bonded phases. The explanation is to be sought in the actual ''composition'' of the preferentially solvated macromolecules and bonded alkane groups. The bonded phase probably has to be a slightly better ''solvent'' than the eluent for a polymer species to cause their retention. Enthalpic partition of PS plays an especially important role in DMF/THF mixed eluents. The results indicate, however, that only three to five terminal -CH 2 -groups plus the methyl end-group take part in the enthalpic partition process. This means that silica gel bonded with shorter alkane groups may be advantageous compared to the C-18 packings in some coupled high performance liquid chromatography methods for synthetic polymers, combining entropic and enthalpic retention mechanisms.log V h vs. V R for bare Kromasil (&), as well as for C-18 (^), C-8 (!), C-4 (~) and C-1 (*) phases.

“…This ingenious idea was for the first time in practice employed by Zimina et al [22][23][24] and afterward by numerous other authors [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Later, some uncertainty was expressed concerning straightforward universal applicability of LC CC for molecular characterization of complex polymers including determination of molar mass average and dispersity of the noninteractive blocks in diblock copolymers [41][42][43], however they mostly remained overlooked. The task of this work is a brief review of selected shortcomings of LC CC and in particular of the issues connected with its application to block copolymers.…”

Brief elucidation is presented of potential difficulties the researcher can face in the course of the molecular characterization of block copolymers with help of liquid chromatography under critical conditions. The impediments include the demanding identification of critical conditions, the limited area of applicable polymer molar mass, the high sensitivity of critical conditions toward minute changes in experimental conditions including changes in the interactivity of the column packing, extensive band broadening, limited sample recovery, pressure effects, detection problems, coelution of block copolymers with their noninteractive parent homopolymers, possible effect of the noninteracting chains of block copolymers on the behavior of the interacting blocks, and role of preferential solvation of macromolecules in mixed solvents. These matters may complicate proper data evaluation and challenge the exactness of results obtained. Special attention is paid to the so far neglected phenomena of preferential solvation, which may affect not only detection of block copolymers but also their retention. The latter occurrence is demonstrated by the behavior of both poly(methyl methacrylate)s eluted from bare silica gel in a mixed eluent tetrahydrofuran plus toluene and polystyrenes eluted from silica gel C18 bonded phase with the mobile phase of tetrahydrofuran/n-hexane.
