Abstract

Abstract Background The circadian clock integrates external environmental changes into the internal physiology of organisms. Perturbed circadian clocks due to misaligned light cycles increase the risk of diseases, including metabolic disorders. However, the effects of sex differences in this context remain unclear. Methods Circadian misalignment was induced by a chronic jet lag (CJL) shift schedule (light-on time advanced by 6 h every 2 days) in C57BL/6N male and female mice. Core body temperature and activity rhythms were recorded using a nano tag, and the gene expression rhythms of clock and clock-controlled genes in the liver and adrenal glands were analyzed using qPCR. Glucose metabolism and insulin response were evaluated using glucose tolerance, insulin sensitivity, and glucose response assays. Castration and testosterone replacement were performed to assess the fundamental role of testosterone in male phenotypes under CJL. Results Under CJL treatment, male mice exhibited increased weight gain, whereas females exhibited decreased weight gain compared to that of the respective controls. CJL treatment induced a lower robustness of circadian rhythms in core body temperature and a weaker rhythm of clock gene expression in the liver and adrenal glands in females, but not in males. Only male mice exhibited glucose intolerance under CJL conditions, without the development of insulin resistance. Castrated mice without testosterone exhibited decreased weight gain and reduced robustness of body temperature rhythm, as observed in intact females. Testosterone replacement in castrated mice recovered the CJL-induced weight gain, robustness of temperature rhythm, and glucose intolerance observed in intact males. Conclusions Significant sex-based differences were observed in circadian clock organization and metabolism under CJL. Testosterone plays a crucial role in maintaining the circadian clock and regulating CJL metabolism in males.

Abstract

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB’s distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role.

Abstract

Social role theory posits that binary gender gaps in agency and communion should be larger in less egalitarian countries, reflecting these countries’ more pronounced sex-based power divisions. Conversely, evolutionary and self-construal theorists suggest that gender gaps in agency and communion should be larger in more egalitarian countries, reflecting the greater autonomy support and flexible self-construction processes present in these countries. Using data from 62 countries (N = 28,640), we examine binary gender gaps in agentic and communal self-views as a function of country-level objective gender equality (the Global Gender Gap Index) and subjective distributions of social power (the Power Distance Index). Findings show that in more egalitarian countries, gender gaps in agency are smaller and gender gaps in communality are larger. These patterns are driven primarily by cross-country differences in men’s self-views and by the Power Distance Index (PDI) more robustly than the Global Gender Gap Index (GGGI). We consider possible causes and implications of these findings.

Abstract

Precarious manhood beliefs portray manhood, relative to womanhood, as a social status that is hard to earn, easy to lose, and proven via public action. Here, we present cross-cultural data on a brief measure of precarious manhood beliefs (the Precarious Manhood Beliefs scale [PMB]) that covaries meaningfully with other cross-culturally validated gender ideologies and with country-level indices of gender equality and human development. Using data from university samples in 62 countries across 13 world regions (N = 33,417), we demonstrate: (1) the psychometric isomorphism of the PMB (i.e., its comparability in meaning and statistical properties across the individual and country levels); (2) the PMB’s distinctness from, and associations with, ambivalent sexism and ambivalence toward men; and (3) associations of the PMB with nation-level gender equality and human development. Findings are discussed in terms of their statistical and theoretical implications for understanding widely-held beliefs about the precariousness of the male gender role. © The Author(s) 2021.

Abstract

This paper proposes a novel algorithm to accurately calculate the coordinates of homoclinic points observed in discrete-time dynamical systems. The proposed method is based on the particle swarm optimization method. Compared with the current methods, the proposed methodology has the advantages of not requiring the careful selection of the initial conditions and not requiring information related to the derivative of the objective function. It is shown that the proposed method can successfully obtain the homoclinic points of a system, even if the system parameters are close to those that describe the homoclinic bifurcation sets of the system; this is achieved via the construction of an efficient objective function that depends on the Euclidean distance between the points in each manifold. We apply the developed method to two- and three-dimensional discrete-time dynamical systems and demonstrate the validity of the algorithm via the numerical work. The reliability of the proposed algorithm was achieved by evaluating a metric based on the success rate of the method.

Abstract

Background: [18F]PSMA-1007, a positron emission tomography (PET) tracer, specifically targets prostate-specific membrane antigen (PSMA), which is highly expressed in prostate cancer. PSMA-PET is effective especially for regional detection of biochemical recurrence, which significantly affects patient management. Herein, we established and optimized a one-step radiolabeling protocol to separate and purify [18F]PSMA-1007 with a CFN-MPS200 synthesizer for clinical application. Results: A dedicated single use cassette and synthesis program for [18F]PSMA-1007 was generated using a single-step method for direct precursor radiolabeling. In the cassette, three tube types (fluoro-elastomer, PharMed® BPT, silicone) and two different precursor salts (trifluoroacetic acid or acetic acid) were compared for optimization. Furthermore, three-lot tests were performed under optimized conditions for quality confirmation. Activity yields and mean radiochemical purity of [18F]PSMA-1007 were > 5000 MBq and 95%, respectively, at the end of synthesis, and the decay-corrected mean radiochemical yield from all three cassettes was approximately 40% using a trifluoroacetic acid salt precursor. Fluoro-elastomer tubings significantly increased the amount of non-radioactive PSMA-1007 (8.5 ± 3.1 μg/mL) compared to those with other tubings (0.3 μg/mL). This reduced the molar activity of [18F]PSMA-1007 synthesized in the cassette assembled by fluoro-elastomer tubings (46 GBq/μmol) compared to that with PharMed® BPT and silicone tubings (1184 and 1411 GBq/μmol, respectively). Residual tetrabutylammonium, acetonitrile, and dimethyl sulfoxide levels were 18F]PSMA-1007 for clinical use and optimized synthesis procedures with a CFN-MPS200 synthesizer using a silicone cassette and acetic acid salt precursor. Cassette availability will facilitate a wide spread use of [18F]PSMA-1007-PET, leading to an effective prostate cancer management.

26. Dynamic resilience and stability of Ecklonia radiata : the importance of density-dependent ecosystem engineering feedbacks

Author

Tatsumi, M

Abstract

Kelps are the dominant marine ecosystem engineers of temperate subtidal rocky reefs around the globe. Kelp forests create a complex habitat structure, modify abiotic factors and support diverse and highly productive systems. However, kelps face several threats and degradation of kelp forests has been reported in a number of places including south-eastern Australia. To date, most studies of threats to kelps focus on how external factors contribute to the degradation but there are also important internal drivers that will also influence kelp stability and resilience. Because ecosystem engineers modify the abiotic and biotic environment, the changes they make may positively feedback to affect their own demography. Consequently, a decline in adult density may lead to a decline in engineering capacity, a change in the modified conditions and reduction in, or loss, of positive effects. Ecklonia radiata is the most widespread habitat-forming kelp in Australia, however, range of stressors, such as ocean warming, more severe and frequent storms, overgrazing and pollution have been impacting its populations causing localised declines in population density. Although studies have been conducted to understand the implications of these changes, how a decline in adult density will affect the demography (reproduction, recruitment, post-recruitment growth and survivorship) of E. radiata are poorly understood. The central aims of this thesis were to determine; (i) how a decline in the density of Ecklonia affects engineering of critical abiotic factors and the link between those abiotic changes and both the understory community and Ecklonia reproduction, recruitment and post-recruitment growth and survivorship, (ii) whether abiotic factors modified by E. radiata were important mechanisms affecting the early post-recruitment survivorship and growth of E. radiata sporophytes, and; (iii) how density-dependent effects on reproductive output affected recruitment of both gametophytes and sporophytes. Chapter 2 presents a study where I manipulated the density of adult E. radiata in a field experiment for 24 months to four different levels (zero, low, medium and high) and measured changes to abiotic factors, associated understory algae and E. radiata recruit demography. These manipulations revealed density-dependent engineering of some, but not all abiotic factors. Most notably, light increased as E. radiata density decreased; scour increased at low and medium E. radiata densities compared to high; while sediment accumulation increased in the absence of E. radiata compared to any treatments with E. radiata. Despite some density-dependent changes in abiotic factors, the understory algal community and demography of E. radiata recruits did not always reflect these changes due to large variation in these metrics within the density treatments which highlighted the variable nature of these processes acting on small-spatial scales on natural reefs. In chapter 3, I manipulated three modified abiotic factors (light, scour and water flow) in the field to identity their role as mechanisms affecting the survivorship and growth of early sporophyte recruits. Overall, this experiment revealed low light / low scour (ambient flow) as important for very small / early sporophytes, but the response of slightly larger sporophytes was more complex. By week 6 in the absence of scour, light and water flow interacted and the highest survivorship occurred with ambient flow/low light and low flow/ambient light. Importantly, these larger sporophytes respond positively and grow much faster under higher light. Chapter 4 tested density-dependent issues related to reproduction. Specifically, how reproductive capacity of E. radiata in the field (the amount of zoospores released per individual) was affected by adult E. radiata density and how recruitment of microscopic stages (gametophytes and sporophytes) was influenced by zoospore density in two different seasons. Zoospore released per individual did not vary greatly in relation to adult density indicating that the total amount of zoospores produced in a E. radiata forest is likely to increase as the number of reproductive adults increases. Gametophyte and sporophyte recruitment were dependent on the density zoospores, with clear optimal ranges (90-355 mm\(^{-2}\) in spring and 21-261 mm\(^{-2}\) in winter) and threshold densities (< 6.5 mm\(^{-2}\) in spring < 0.5 mm\(^{-2}\) in winter) of zoospores for successful recruitment. Overall, this study indicates that some abiotic factors (light, scour and sediment accumulation) change in response to a declining density of Ecklonia and that low scour and combinations of light and water flow are important to post-recruitment survivorship and growth. However, the evidence for the break-down of a positive demographic feedback with a decline in E. radiata density was not strong. Nonetheless this study did indicate that a high density of reproductive E. radiata sporophytes is likely to result in a high density of zoospores and subsequently higher recruitment of microscopic sporophytes beneath the canopy. The sub-canopy conditions beneath a high-density E. radiata forest (low light, reduced scour and understory algal abundance) are also likely to result in high survivorship of microscopic sporophytes. Once light increases due the creation of localised gaps in the canopy, these recruits grow fast allowing the canopy to reform highlighting a key component to the resilience of E. radiata forests.

Abstract

Abstract Aims/Introduction In Japan, the increasing frequency of underweight among women of reproductive age and the accompanying increase in the rate of low birth weight (LBW) are social issues. The study aimed to establish a prospective registry system for gestational diabetes mellitus (GDM) in Japan and to clarify the actual status of GDM according to the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria. Materials and Methods Pregnant women with gestational diabetes mellitus and those in the normal glucose tolerance (NGT) group were enrolled in the Diabetes and Pregnancy Outcome for Mother and Baby study from October 2015. Pregnant women with positive glucose screening in early and mid‐to‐late pregnancy underwent a 75 g oral glucose tolerance test by gestational week 32. Gestational diabetes mellitus was diagnosed according to IADPSG criteria. Women with a positive glucose screening test at mid‐to‐late pregnancy but NGT were enrolled as references (NGT group). Treatment for gestational diabetes mellitus and maternal and neonatal pregnancy data were prospectively collected on outcomes. Results In total 1,795 singleton pregnancies (878 women with GDM and 824 NGT women) were analyzed. The risk of LBW and small‐for‐gestational age in the GDM group was significantly higher than in the NGT group. A similar relationship was found for LBW risk in the non‐overweight/obese group but not in the overweight/obese group. Conclusions We established a prospective GDM registry system in Japan. In the management of GDM in Japan, suppression of maternal weight gain may be associated with reduced fetal growth, especially in non‐overweight/obese women with GDM; however, further investigation is required.

Abstract

Abstract Background This study investigated the sex differences in the risk of end‐stage kidney disease (ESKD) and mortality, as well as the effect modification of sex on associated factors in patients with type 2 diabetes. Methods This multicenter observational cohort study included 4328 patients with type 2 diabetes. Hazard ratios (HRs) with 95% confidence intervals (CIs) of sex for ESKD and death were estimated using Cox proportional regression with adjustment for baseline covariates. For assessing risk modification, HRs and incidence rates for ESKD and death were compared between sexes across patient characteristics using Cox proportional and Poisson regression models. Results During a median follow‐up of 7 years, 276 patients (70% men) developed ESKD, and 241 patients (68% men) died. Men had higher risks of ESKD (HR 1.34; 95% CI 1.02–1.75; p = .034) and death (HR 1.64; 95% CI 1.24–2.16; p = .001) versus women after adjusting for multiple covariates. Among patients with microalbuminuria, men had a substantially higher risk of ESKD versus women, compared to those with normo‐ and macroalbuminuria (p for interaction .04). Incidence rates were also increased in men versus women with albuminuria of around 300 mg/g. No differences were detected in the association of sex and death across baseline patient subgroups. Conclusions In type 2 diabetes, men had an increased risk of ESKD and death versus women. Moderately increased albuminuria was strongly associated with sex difference in developing ESKD.
