Background: Sexual health is a fundamental pillar of well-being during the perinatal period. However, many studies suffer from scoring bias associated with zero values by failing to distinguish between women who are sexually inactive and those with physiological dysfunction. This study aimed to identify the distinct sociodemographic and psychological determinants of sexual inactivity versus sexual dysfunction quality in a Romanian perinatal cohort. Methods: An observational, cross-sectional study was conducted with 100 women (52% sexually active, 48% inactive). Participants were evaluated using the Female Sexual Function Index (FSFI), Patient Health Questionnaire-9 (PHQ-9), RSES (Rosenberg Self-Esteem Scale), and Generalized Anxiety Disorder-7 (GAD-7). Data were analyzed using binary logistic regression for activity status and multiple linear regression for functional quality. Results: Among sexually active women, 84.6% met the clinical criteria for sexual dysfunction (median FSFI = 21.6). Binary logistic regression revealed that self-esteem (RSES) was the sole independent predictor of sexual activity status (aOR = 1.144; 95% CI: 1.028–1.217, p = 0.016). Conversely, multiple linear regression showed that depression (PHQ-9) was the only significant independent predictor of functional quality (B = −0.73, p = 0.006). Maternal age, residence, and obstetric history did not significantly predict either outcome. Conclusions: Based on the findings of our preliminary, exploratory study, we propose a conceptual interpretation, framing perinatal sexuality as a potential two-stage process, where self-esteem appears to serve as a primary behavioral barrier for the resumption of intimacy, while depression serves as the primary disruptor of functional quality. Clinical interventions may benefit from moving beyond physical recovery to include psychological screening for body image and mood disorders to restore sexual quality of life. Full article

The Southern Stuttering Frog, Mixophyes australis, is a newly described threatened species endemic to Australia that is suffering severe and ongoing declines. The species is currently presumed extinct from the southern two thirds of its range, primarily driven by the amphibian chytrid fungus (Batrachochytrium dendrobatidis; Bd). In response to the species’ decline, a conservation breeding program (CBP) was established at Symbio Wildlife Park to secure an insurance population and support future reintroductions. Herein, the establishment and management of the CBP for M. australis is described. We detail the captive husbandry framework and tracing progress from the collection of 200 wild-caught tadpoles in April 2022, through to the successful reproduction of the founder colony. Following the revision of husbandry and water management practices, and disease treatment in quarantine to overcome initial mortality, 89 Bd-free individuals were transferred to the breeding facility to establish the insurance colony. Critically, the program has achieved consistent and successful reproduction commencing in April 2024, within 2 years of tadpole collection. The breeding cohort exhibited a distinctive bimodal annual reproductive pattern in captivity, with clear peaks in breeding activity in Austral autumn (March–May) and mid-winter to early spring (July–September). We detail effective husbandry protocols for all life stages of the species, which has resulted in the generation of clutches exhibiting high fertility and high tadpole survivorship. Overall, the program to date has contributed to the reintroduction of over 7700 first-generation (F1) tadpoles and 59 head-started founder (F0) adults across 15 release sites within the species’ historical range in NSW. Herein, we provide important natural history data for the species and considerations for their breeding in captivity, which can inform future conservation efforts for this and other threatened frog species globally.

Insect migration is an energetically costly process often involving a trade-off with reproduction. However, how adult nutritional stress regulates resource allocation between these two life-history traits remains unclear. Here, we compared morphological traits, flight performance, ovarian development, fecundity, and energy reserves between migrants and residents of Cnaphalocrocis medinalis under fed and starved conditions. Morphological analyses showed no significant differences in body weight, body length or forewing length between migrants and residents, regardless of nutritional status. Under starvation, migrants exhibited significantly greater flight distances and speeds than residents, and their flight distance and duration were also higher than those of fed migrants. Starved migrants showed a higher proportion of immature ovaries and higher fecundity, accompanied by a prolonged pre-oviposition period, indicating reproductive delay. Under fed conditions, ovarian development and fecundity were similar between migrants and residents. Energy reserve assays revealed that starved migrants accumulated more abdominal triglycerides but had lower thoracic glycogen than residents, suggesting preferentially triglyceride storage in the abdomen for long-distance flight. Under fed conditions, residents possessed higher thoracic glycogen levels than migrants, whereas no differences were observed in triglyceride levels. These results indicate that C. medinalis prioritizes energy allocation to migration over reproduction under energy shortage, but switches to a strategy that simultaneously meets the demands of both when nutrition is sufficient. Our findings underscore the role of adult nutrition in mediating the energy allocation between migration and reproduction, offering a scientific basis for the precise monitoring and management of this pest.

This paper focuses on the early Qing monk-painter Hongren 弘仁, systematically exploring the pathways through which the Chan Buddhist “emptiness contemplation” is manifested in his landscape paintings. As a representative monk-painter, Hongren produced works that profoundly embody the Chan contemplation of emptiness, yielding a singular style defined by austere coldness, minimalist simplicity, and profound quietude. Transcending conventional stylistic descriptions in art history and essentialist philosophical deductions, this study adopts a comprehensive empirical approach that integrates poetry, calligraphy, painting, and seals (shi-shu-hua-yin 诗书画印). By adopting an interdisciplinary perspective of philosophy, religion, and art history, this study argues that Hongren’s landscapes are not merely subjective emotional expressions or aesthetic pursuits; rather, they constitute a visual extension and a spiritual externalization of his emptiness contemplation. Through a multi-layered analysis of his form, brushwork, composition, and artistic conception, combined with the mutual corroboration of poetic inscriptions on paintings and textual inscriptions on seals, this paper reveals how the Chan philosophy of “emptiness contemplation” is reflected within his artistic language. While Hongren’s style is the cumulative result of various factors such as the Ming-Qing dynasty transition, his personal life, the inheritance of painting techniques, and the regional culture of Mount Huang, this paper specifically takes Chan thought as its analytical starting point, focusing on its unique expression in his work. Hongren’s path of “Painting-Chan” (hua chan 画禅) not only infused early Qing painting with a sublime spiritual power but also provides a vital religious exegesis of the deep-seated Chinese tradition of “Technique Ascending to the Dao” (ji jin yu dao 技进于道).

In her final novel, Daniel Deronda (1876), George Eliot (1819–1880) repeatedly stages moments in which gentile characters project expectations onto Jewish women, drawing on inherited cultural representations from literature, history, and the performing arts. These moments reveal how limited their real-world knowledge of Jews—particularly Jewish women—was, and how readily they relied on cultural templates rather than lived experience. George Eliot herself, however, had undertaken extensive study of Jewish history, religion, and culture in preparation for the novel, including research into the Talmud, Mishna, kabbalah, and halacha (Jewish law). Yet this knowledge is purposefully not afforded to her characters. This article examines George Eliot’s increasing understanding of Jewish society, and her shifting attitudes towards Judaism, and explores how allusions to Jewish women in history, literature, and performance shape the gentile characters’ othering of Mirah Lapidoth, a young Jewish woman fleeing enforced familial exploitation, whom Daniel rescues from drowning in the Thames. Two significant conceptual terms underpin my argument. Objectification refers here not only to eroticisation or aestheticisation, but to the broader process by which Mirah is perceived as a symbolic figure—as an image, a type, or role—rather than a fully realised person. Othering denotes the interpretative habit by which gentile characters position Mirah through pre-existing stereotypes or literary precedents, instead of understanding her as a subject with her own history and interiority. Rescue describes the narrative mechanisms by which Mirah is brought into focus, first through Daniel’s intervention, then through her placement within the Meyrick household, and finally through marriage, though always within structures that continue to idealise, discipline, or contain her. I argue that George Eliot’s deployment of familiar stereotypes does not reinforce them; instead, she exposes them as cultural constructions that must be deconstructed or exorcised before she reconstructs her own version of Jewish culture and identity, which she referred to as “the inner life of modern Judaism” in her notebooks. I also argue that Daniel’s rescue of Mirah, rather than an act of pure benevolence, becomes a further site of objectification, othering her as an idealised model of Jewish womanhood rather than acknowledging her as an autonomous individual.

Background/Objectives: Given that post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG) are separate constructs that can co-occur following adversity, we examined how prior adversity and current functioning difficulties may relate to the likelihood of meeting criteria for PTSD and scoring above the cutoff for PTG among individuals who reported being impacted by their prior adversity. Methods: Participants (n = 2112) in this international sample completed online measures assessing their adversity history, current functioning difficulties (i.e., negative world assumptions and autonomic reactivity), PTSD symptomatology, and PTG. Results: Chi square analyses suggested a trend toward an association between meeting criteria for PTSD and scoring above the cutoff for PTG, although not statistically significant (p = 0.061). Multivariable logistic regression analysis found that individuals most impacted by caregiver abuse and certain specific adversities (i.e., parent with a mental health problem, caregiver and non-caregiver sexual abuse, and being held captive) were more likely to meet the criteria for PTSD. Whereas those most impacted by life-threatening situations and the specific adversities of being impacted by a life-threatening illnesses or injury, were more likely to meet the criteria for PTG. However, the strongest predictor of the likelihood of PTSD was increased autonomic reactivity, and the strongest predictor of the likelihood of PTG was fewer negative world assumptions. Conclusions: Our research suggests the need to assess the perceived impact of adversity history, as well as the potential negative consequences of autonomic reactivity and negative world assumptions, as these may be associated with PTSD symptomatology and PTG.

The Seven-coloured Tanager Tangara fastuosa is a threatened species, with little data available on its reproduction. Between 1987 and 2025, 29 nests were found around the Pedra Talhada Biological Reserve in Quebrangulo, Alagoas, north-eastern Brazil. Nests were cup-shaped, with average external dimensions of 11.0 × 7.3 cm and average internal dimensions of 6.2 × 3.7 cm. They were built at an average height of 5.4 m above ground. Mean clutch size was 2.7 eggs, which measured 20.9 × 15.6 mm, and weighed 2.6 g. Eggs were beige in colour with greenish undertones and were heavily spotted with purple or rusty brown. Average incubation period was 13.8 days, and average nestling period was 15.4 days. Apparent nest success was 51.7%, with predation being the main cause of nest failure. Parents, sometimes assisted by helpers, fed the nestlings with small fruits, fruit pulp, seeds, and various arthropods. Our records provide new information on the reproduction of this species in interior and edge forests. However, forest destruction and capture for the illegal wildlife trade pose a threat to the survival of its populations, both remaining an issue in the study area. Full article

Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is highly prevalent worldwide and is the third leading cause of death. While some aspects of the disease were known since the Enlightenment, Laennec’s work in the 19th century began the process of our current understanding of this disease. In this narrative review, 13 clinicians and scientists with over three centuries of cumulative experience treating and studying COPD give their perspectives on the science underpinning our modern concept of this disease and its management. These include (1) the challenges of coming up with a name for what is a complex syndrome; (2) the evolution of our thinking on the natural history of the disease; (3) the importance of particulate matter inhalation in its pathogenesis; (4) the often-overlooked but important—and often treatable—systemic effects of the disease that contribute to its morbidity and mortality; (5) the changes in our perspective of not just addressing pathologic or physiologic abnormalities but also measuring outcomes, such as breathlessness or health-related quality of life, that are of considerable importance to the patient; (6) the role of pharmacologic therapy in not only providing symptomatic relief by increasing airway caliber but also in disease modification, especially by reducing exacerbation frequency; (7) lung hyperinflation as an essential feature of COPD pathophysiology, driving symptom burden, exercise limitation, and mortality risk; (8) long-term oxygen therapy, despite being demonstrated to prolong survival in a defined set of hypoxemic patients with COPD, still having unanswered questions regarding its application and delivery; and (9) pulmonary rehabilitation, a major component of the non-pharmacologic treatment of COPD patients and prominently situated in clinical guidelines for this disease. While this, by necessity, must be a brief review of a very complex disease, the perspectives of these esteemed clinicians and scientists should be of use to other clinicians in understanding and managing this disease.

Tropical lignocellulosic residues are increasingly relevant feedstocks for lignin-containing nanocellulose composites, but their performance cannot be predicted from botanical origin or bulk lignin percentage alone. This review defines the interface as the geometrical boundary between phases and the interphase as the finite, compositionally graded region in which lignin distribution, nanocellulose morphology, adsorbed water, and the surrounding matrix jointly govern stress transfer and mass transport. Using an evidence-weighted framework, the literature is organized into the following categories: residual-lignin nanofibrils, redeposited-lignin systems, lignin nanoparticle assemblies, compatibilized thermoplastic hybrids, and all-lignocellulosic sheets. Representative quantitative observations show that controlled residual lignin can the increase water contact angle from approximately 35 degrees to 78 degrees and reduce oxygen permeability by up to 200-fold in nanopapers, while selected PLA/LCNF systems show tensile-strength and modulus increases of 37% and 61%, respectively; however, high or poorly distributed lignin can suppress fibrillation, lower viscosity, weaken gel networks, and reduce reproducibility. The most defensible near-term product windows are packaging layers, grease/oil barrier papers, coatings, paper-like multilayers, and selected porous media. Thermoplastic matrices remain process-sensitive, and biomedical, additive-manufacturing, nano-reactor, and energy-material claims require stronger validation of the extractables, rheology, humidity history, TEA/LCA metrics, and end-of-life behavior. This review, therefore, provides a critical, application-backward roadmap for tropical biorefineries in which interfacial function, wet handling, drying energy, and process integration are assessed together rather than treated as independent variables. The abbreviations used in the abstract are defined as follows: CNFs, cellulose nanofibrils; CNC, cellulose nanocrystals; LCNF, lignin-containing cellulose nanofibrils; LCNCs, lignin-containing cellulose nanocrystals; PLA, poly(lactic acid); PHB, polyhydroxybutyrate; PHAs, polyhydroxyalkanoates; PVA, poly(vinyl alcohol); DESs, deep eutectic solvents; TEA, techno-economic analysis; LCA, life-cycle assessment; ML, machine learning.

The sandfish (Arctoscopus japonicus) is an important fishery resource in the East/Japan Sea; however, its stock has recently declined sharply. Most ecological studies were conducted before the mid-2000s, limiting our understanding of recent ecological changes under rapidly changing environmental conditions. We aimed to analyze recent ecological characteristics of sandfish, including growth, maturation, and feeding ecology, in eastern Korean waters. Sandfish samples collected between 2021 and 2024 were analyzed. Age and growth were estimated using otolith-based analyses and the von Bertalanffy growth function. Maturation characteristics were evaluated using gonadosomatic index and maturity-stage analyses, and feeding ecology was assessed through stomach content analysis. Younger individuals (aged 1–2 years) exhibited larger body sizes than previously reported, whereas older individuals (3–5 years) exhibited relatively smaller body sizes. The peak spawning period occurred from December to January, indicating a delay in spawning compared with earlier studies. The length at 50% maturity was estimated at 16.3 cm, corresponding to 1.72 years. Euphausiacea and Amphipoda were the dominant prey items. These findings provide updated baseline information on recent ecological changes in sandfish populations and may support future stock assessment and fisheries management. Continued long-term monitoring is needed to better understand environmental influences on sandfish ecology. Full article

The Dwarf Ombú, Phytolacca tetramera, is a rare and highly unusual plant endemic to the northeastern Pampean grasslands of Argentina and is currently considered of high conservation priority. In order to better understand its biology, ecology, and conservation requirements, we studied its anatomy, reproductive traits, life history, and distribution based on field observations and herbarium material. Our results show that P. tetramera possesses a combination of traits consistent with the concept of ecological anachronism. The species produces large fleshy fruits whose size and shape are comparable to those interpreted as adapted for dispersal by extinct megafauna. In addition, the plant exhibits morphological and ecological adaptations associated with intense grazing, trampling, and drought tolerance, including robust underground structures and a growth pattern comparable to underground trees from seasonally dry open habitats. These findings suggest that P. tetramera evolved under ecological conditions markedly different from those existing today, including megafaunal disclimax environments that disappeared after the late Pleistocene extinctions. This ecological mismatch may help to explain its present rarity, fragmented distribution, and low population numbers. Our results also indicate that current conservation strategies for P. tetramera should consider the role of disturbance regimes and extinct ecological interactions in shaping the biology of this species.

This paper argues that the central thesis of Wael Hallaq’s The Impossible State is that traditional Islamic cultures as shaped by Sharīʿa did not abide by a fact-value distinction. Hallaq’s incisive account of traditional Islamic socio-political culture has relevant repercussions beyond the Islamic context from which he draws his conclusions. The importance of Hallaq’s project stems from how it reconstructs a specific tradition—Islam—to contest logics presented as modern and universal. His central argument, that the modern (Western) state is ultimately organized around a fact-value distinction, bears crucially on analyses of the historical Chinese state and its “modernization.” As this paper shows, the Chinese were the first to invent the modern bureaucratic state that Hallaq problematizes in his account of post-feudal European “modernity.” The critique that Hallaq makes of this modern bureaucratic state finds resonance throughout the millennia of Chinese history. Historically, the Confucians argued against the proponents of a similar fact-value distinction in political life—the “legalist” (fajia, 法家). Philosophically, the Confucians had conclusively won the debate against the legalists in dynastic China and the historic Chinese state and its political culture disavowed of the kind of fact-value distinction championed by the legalists. However, in contemporary times, due to the attempt by Western knowledge production to globalize the “modern” state, there has been a revival of legalism by Western scholars. This paper situates the revival within the context of Hallaq’s powerful critique, which frames the West’s attempt to globalize its political models as a form of epistemic colonization. Full article

In southern China, Chinese milk vetch is used as green manure to substitute for inorganic nitrogen (N) fertilizers and improve soil fertility, but how different incorporation methods affect its decomposition and underlying microbial mechanisms is unclear. This study used four fertilization regimes (CK: no N; CF: sole chemical N; CM: sole vetch; CMCF: vetch + 40% reduced N) to evaluate bacterial diversity, community composition and life history strategies during early vetch decomposition, and the nylon bag method to compare decomposition and C/N release dynamics. The results show that vetch dry matter decomposition reached 81.9–85.2% in 34 days, slowing to 11.8–14.4% after 192 days. CMCF significantly accelerated early decomposition and N release compared with CM. While CMCF reduced the bacterial Ace and Chao indices compared to CK with similar community structure, CF/CM exhibited distinct community structures. Compared to CM, CMCF increased r-strategy bacteria (e.g., Proteobacteria, Bacteroidota) and decreased K-strategy ones (e.g., Chloroflexi). Furthermore, decomposition rate positively correlated with r-strategy and negatively with K-strategy bacteria, with soil temperature as the primary driver. Compared to CMCF, CM reduced bacterial network complexity, decreasing nodes by 63.6% and average degree by 68.5%. In conclusion, combining vetch with chemical N enhances vetch residue decomposition while preserving microbial network structure and functional diversity. Full article

Many filter-feeding invertebrates consume microplastics (MP) under laboratory conditions, but little is known about newly settled, field-collected juveniles. To address this information gap, we collected 3439 juvenile invertebrates in the Indian River Lagoon (IRL), FL, USA. Previous studies suggest that the IRL is a MP hotspot. A total of 70% of IRL adult oysters (Crassostrea virginica) contained MP (mean: 2.3 MP/individual), and MP number and MP length were positively correlated with animal size. We predicted that juvenile C. virginica and other sessile invertebrates would contain MP with a positive correlation to animal size. Five species were examined; 51% were C. virginica (mean shell length ± SD: 6.3 ± 4.7 mm). Overall, 117 (3.4%) animals contained potential MP (fibers: 90.7%). Of these particles that matched FTIR databases with a score of 70% or greater, 51% were plastic and 49% were anthropogenically modified particles. No correlations to animal size were found for particle presence (logistic regressions: p ≥ 0.20 for all species) or particle length (linear regressions: p ≥ 0.23 for all species). Thus, even though found in a MP hotspot, our extrapolated results suggest few juveniles (<1%) contained MP. This information is important for understanding the relationship between MP and the life histories of filter-feeding animals, especially for species considered biological indicators of MP.

Pacific sardine (Sardinops sagax) are an economically important forage fish in the Northeast Pacific Ocean that undergo large changes in abundance over decadal scales and exhibit high individual variation in somatic growth. Past studies have suggested that somatic growth in Pacific sardine may be density-dependent and vary regionally in response to environmental conditions. We analyzed somatic growth in Pacific sardine off the U.S. Pacific Coast during the recent period of low abundance (2012–2021) and compared the results to those of previous studies to evaluate evidence of spatial or temporal variation in growth. Sampled fish (n = 3228) ranged in length from 30 to 291 mm SL and in age from 0 to 9 years and displayed high individual variation in length-at-age and age-at-length. Length-at-age data were best explained by the von Bertalanffy growth model, and sample distribution simulations showed the dataset to be robust and unbiased. Estimated growth parameters (L_∞ = 243, K = 0.795, t₀ = −0.638) were consistent with an opportunistic life history strategy characterized by rapid growth, early maturation, and a short lifespan. While the estimated growth rate (K) was higher than in a previous study conducted during a period of high abundance and indicated that growth may be density-dependent, the parameter estimates from the previous study were influenced by sample distribution bias. Similarly, differences in study region, season, collection method, aging methods, and other factors precluded any definitive conclusions on the source of reported differences in growth patterns among studies.
