AbstractAnnual bluegrass (Poa annua L.) poses significant challenges in managed turfgrass systems due to its adaptability and resilience. This study explores publicly available information on and performance of several organic or nonsynthetic herbicides for annual bluegrass control in turfgrass to address this issue. Through a keyword frequency analysis using Google and Google Scholar, the prevalence of organic weed control treatments was examined, revealing a significant association between search engines, key phrases, and weed management types and general dominance of synthetic herbicides despite phrases specifically targeted at organic options. Field assessments were conducted at 20 site years across four US states to evaluate the efficacy of 14 nonsynthetic herbicides for annual bluegrass control while considering turfgrass safety. Results indicate that nonsynthetic herbicides fail to provide long‐lasting control of annual bluegrass when applied once and injure turfgrass. The study highlights the challenges in achieving long‐term control of annual bluegrass, especially with nonsynthetic herbicides, which have limited effectiveness against established weeds. Cost and environmental considerations further complicate the adoption of organic or nonsynthetic weed management programs, despite their perceived environmental benefits. Overall, the research underscores the need for continued exploration of integrated weed management strategies, including targeted application methods, to address the complexities of annual bluegrass control in turfgrass systems.
Short‐ and long‐term casting dynamics of the anecic earthworm Aporrectodea longa in golf course turfgrass following sand topdressing
Authors: McGraw B. A. , Kline D. E. 
Published: February 2025

AbstractThe use of sand topdressing has been hypothesized to reduce earthworm casting activity in turfgrass, but these assumptions are primarily based on anecdotal evidence and lack robust empirical support. In temperate regions of North America, many golf courses have adopted the practice of topdressing large turf areas, such as fairways, with sand to mitigate casting. This practice is relatively costly, and there is limited empirical evidence to substantiate its effectiveness. To address this gap, a 3‐year field study was conducted on Agrostis stolonifera research fairways grown on a clay loam to evaluate the impact of two annual topdressing rates on the casting activity of the anecic earthworm species, Aporrectodea longa Ude. Topdressing was applied four times annually across the season at two different volumes. Weekly cast counts from the experimental plots showed little to no impact on short‐term dynamics and no statistical differences between the two topdressing rates and the untreated control plots throughout the duration of the study. Furthermore, the moderate (1.25 cm annually) and heavy topdressing (2.5 cm) rate increased casting by 13%–31% and 25%–31% in 2018 and 2019, respectively. Rates were quadrupled in 2020, and yet casting in moderate‐topdressing (19%) and heavy‐topdressing (25%) treatments exceeded those in controls. Given the lack of efficacy observed in this study and the associated costs, the practice of topdressing as a strategy to control earthworm casts warrants further scrutiny and reconsideration in turf management programs.

AbstractThe dopant elements of ZnO matrix play a crucial role in enhancing the performance of desired properties. Hence, in this article we introduce a comparative study between 1% Si and 1% Nb‐doped ZnO properties. The structural investigation proves the successful preparation of Si and Nb‐ doped ZnO. In addition, the impedance spectra of Nb‐doped ZnO are well adjusted using an equivalent circuit formed by serial contributions of two parallel resistance R and constant phase element (CPE). Thus, we demonstrate that the capacitive behavior is due to improved grain boundary effect. While ZnO:Si impedance spectra are modeled by a circuit formed by a parallel connection of a resistance R and a capacitance C. In addition, ZnO:Nb exhibits thermally activated DC conductivity, while ZnO:Si conductivity is quasi‐independent of temperature. With Si doping, dielectric properties shift to those of an insulator. Moreover, the obtained results prove Nb‐doping can be a promising route to make ZnO a good candidate for applications as thermistor with a Negative Temperature Coefficient (NTC). In addition, Si, Nb doped ZnO show excellent photocatalytic performances in methylene blue degradation, that reached 97% under solar light illumination for 105 min. This makes them promising candidates for wastewater purification.

Published: February 2025

AbstractPurpose/ObjectivesThis study examined the relationship between environmental factors (e.g., working position, patient position, and scaling instruments) and poor posture in dental hygiene students.MethodsA longitudinal cohort study was conducted from 2017 to 2019 to observe dental hygiene students' clinical rotation performance at two undergraduate universities. Samples of video observations (n = 1487) of dental hygiene students performing scaling activities during oral care sessions were evaluated using the Rapid Upper Limb Assessment (RULA). Descriptive analysis and exploratory prediction modeling were performed to assess clinical environmental factors that predicted higher risks of developing WMSDs.ResultsRULA scores (mean = 4.8, median = 5, range = 2–7) indicate dental hygiene students are at high risk of developing upper extremity MSDs. The type of scaling instrument, clock positioning relative to the patient, and sitting versus standing had statistically significant associations (p < 0.001) with the RULA outcome. In univariate analyses, clock positions 7 and 8 were the worst, having an increased risk of poor RULA outcomes (scores 5–7) by nearly nine times over working in clock position 12 (odds ratio [OR] 9.11, 95% CI 5.48–15.60). Multivariate predictive modeling indicated that the riskiest combination of factors is using a manual scaling instrument (OR 1.67, 95% CI 1.28–2.18), standing (OR 1.42, 95% CI 1.03–1.96), and working clock positions 7 and 8 (OR 8.4, 95% CI 5.02–14.50).ConclusionsThere is a need to consider the combined contribution of multiple environmental factors on working positions to optimize ergonomic training during dental hygiene and protect emerging dental health professionals from the negative health impacts of prolonged awkward postures.

Authors: Lin Bochuan , Wang Jing , Zha Jiansheng , Chang Kuan 
Published: February 2025

AbstractSolubilization of oil‐soluble substances in aqueous solution is essential in daily chemistry. Commonly used synthetic solubilizers are environmentally harmful and have limited applications. In this study, sophorolipid, a biosurfactant, was purified through an efficient, simple, and solubilization‐compatible method, yielding an aqueous acidic sophorolipid (acid‐SL) with high purity of 96 wt%. The bola structure of acid‐SL conferred reversible pH‐responsive micelle behavior and therefore a distinctive solubilization effect on polar small molecules under neutral pH environment. Based on this, the synergistic solubilization effect of acid‐SL in combination with rhamnolipid (RL) was confirmed, with the optimal compound ratio being acid‐SL/RL = 0.95:0.05. The compound system significantly improved the solubilization ability under acidic conditions and had superior solubilization capacity for oil‐soluble substances such as essential oils, fragrances, and preservatives compared to commonly used solubilizers like Polysorbate 20 and Polyoxyethylene 40.
Preparation of Cross‐Linked Sponge With Piezoelectric Properties Based on Low Density Polyethylene/Poly(Ethylene‐ Co‐ Vinyl Acetate) and Barium Titanate: Relationship Between Mechanical Properties, and Cell Structure With Piezoelectric Coefficients

Published: February 2025

ABSTRACTIn this study, cross‐linked foams were developed using a blend of ethylene‐vinyl acetate copolymer (EVA), and low‐density polyethylene (LDPE), incorporated with barium titanate (BaTiO3), to explore their piezoelectric characteristics, as well as the various effective parameters, such as foam density, morphology and crystallization. In this regard, LDPE/EVA blends containing BaTiO3 were prepared through the melt mixing method. In these mixtures, maleic anhydride‐grafted LDPE (LDPE‐g‐MAH) was used as the compatibilizer, followed by forming cross‐linked foams using dicumyl peroxide through the compression molding method. As observed, an increase in EVA content caused a higher rate of crosslinking, decreased cell size, as well as an increase in the gel content. The addition of BaTiO3 to EVA‐dominant composites, due to improved interaction with vinyl acetate groups acting as nucleating agents, resulted in cells smaller than 100 μm in diameter and increased the modulus to 0.63 MPa. EVA‐dominant samples, in comparison to those LDPE dominant, exhibited less hysteresis, higher cell strength, and a faster response rate, leading to enhanced sensor performance and accuracy. The inclusion of the compatibilizer contributed to a higher modulus and finer cell size, attributed to the effective dispersion of BaTiO3 particles within the matrix. Furthermore, the synergistic impact of the cellular structure and BaTiO3 on piezoelectric properties yielded the highest piezoelectric coefficient (0.8 pC/N) in the LDPE‐dominant sample (LDPE/EVA: 70/30 w/w%) containing 20 wt.% BaTiO3, owing to its higher output voltage and lower modulus compared to the other samples.

Published: February 2025

AbstractIn recent decades, polymeric graphitic carbon nitride (g‐C3N4) has garnered significant attention as a class of metal‐free semiconductor photocatalysts. However, inherent limitations such as inadequate visible light absorption, low specific surface area, moderate charge transfer efficiency, and poor crystallinity restrict its application. To address the constraints, three novel donor‐acceptor type covalent heptazine frameworks (CHFs) are constructed through a bottom‐up approach by intergrating heptazine and triazine, which are the fundamental active moieties of g‐C3N4, with diverse donor spacers. Compared to g‐C3N4, noteworthy enhancements in photocatalytic activity and hydrogen evolution efficiency are attributed to the increased specific surface areas, broadened visible‐light absorption, and accelerated photogenerated charge transfer within the CHFs. Notably, high crystallinity shows a profound influence on the photocatalytic efficiency of the synthesized CHFs. Among the CHFs, highly crystalline CHF‐3 stands out to present the highest hydrogen evolution rate of 15284 µmol g−1 h−1 under visible‐light irradiation (420–780 nm) with ascorbic acid as the hole sacrificial agent. This remarkable achievement represents a 144‐fold improvement over g‐C3N4 and a noteworthy sevenfold enhancement compared to the low‐crystalline CHF‐3. These results not only offer valuable insights for the design of efficient heptazine‐based CHF photocatalysts but also contribute toward the advancement of heptazine‐based functional materials.

Self-reported psychological distress in childhood and mental health-related hospital attendance among young adults: a 12-year data linkage cohort study from England
Authors: Baranyi Gergő , Harron Katie , Rajah Nasir , Fitzsimons Emla 
Published: February 2025

Abstract

Purpose
Investigating the relationship between self-reported mental health and secondary care utilisation can provide evidence on the link between population-level common mental conditions and clinical care; however, cohort studies with linked administrative data are rare. We explored the link between self-reported mental health in adolescence and mental health-related hospital attendance in young adulthood.

Methods
Data from a nationally representative English cohort (Next Steps) were linked to NHS Hospital Episode Statistics. GHQ-12 assessed psychological distress in Next Steps at age 15; participants were followed up until their first mental health-related hospital presentations and outpatient treatments or were censored at the end of the study (age 27). Cox proportionate hazard models with survey weights estimated associations.

Results
Out of 4058 young people, 19% reported high levels of distress at age 15. During the 12-year follow-up, 5.3%, 2.9% and 2.7% of the participants had at least one mental disorder, drug/alcohol misuse and self-harm presentation, respectively, and 4.2% had a mental health treatment in NHS hospitals. Higher GHQ-12 scores were associated with mental disorder presentations (HR = 1.10, 95% CI:1.04–1.16), and mental health treatments (HR = 1.14, 95% CI:1.08–1.20). Associations for hospital treatments were weaker for young people living in deprived areas, or if their main parent had lower education.

Conclusion
Adolescent psychological distress is associated with subsequent hospital attendance in young adulthood, but there might be treatment gaps in service utilisation among more disadvantaged individuals. Detecting youth with mental health difficulties may facilitate early intervention, improve life-course outcomes, and ultimately reduce secondary healthcare use.
Asymptotic nonvanishing of syzygies of algebraic varieties
Authors: Park Jinhyung 
Published: February 2025

Abstract
We establish precise nonvanishing results for asymptotic syzygies of smooth projective varieties. This refines Ein–Lazarsfeld’s asymptotic nonvanishing theorem. Combining with the author’s previous asymptotic vanishing result, we completely determine the asymptotic shapes of the minimal free resolutions of the graded section modules of a line bundle on a smooth projective variety as the positivity of the embedding line bundle grows.
Involvement of the GABAergic and the serotonergic systems in the anxiolytic effects expressed by the nitric oxide (NO) donor sodium nitroprusside (SNP) in the male rat
Authors: Parlantza Maria Anastasia , Pitsikas Nikolaos 
Published: February 2025

Abstract

Rationale
Anxiety is a chronic severe psychiatric disorder. In a series of studies, the implication of the gaseous molecule nitric oxide (NO) in anxiety has been evidenced. Further, the outcome of preclinical research suggests that different NO donors, including sodium nitroprusside (SNP), have expressed an anxiolytic profile revealed in animal models of anxiety. Regardless of this, it is not yet clarified the mechanism(s) of action by which SNP induces its beneficial effects on anxiety. In this context, it has been hypothesized that these effects might be attributed to a potential interaction of this NO donor with the GABA type A and the 5-HT1A serotonergic receptors.

Objectives
The current study was designed to investigate this issue in the male rat.

Methods
To this end, the light/dark box and the open field tests were utilized.

Results
SNP (1 mg/kg, i.p.) applied acutely induced an anti-anxiety-like effect evidenced either in the light/dark box or in the open field test. Either the GABAA receptor antagonist flumazenil (10 mg/kg, i.p.) or the 5-HT1A serotonin receptor agonist 8-OH-DPAT (0.25 mg/kg, i.p.) suppressed the above reported anxiolytic effects of SNP.

Conclusions
The results here reported propose a functional interaction between SNP with the GABAergic and the serotonergic systems on anxiety and thus, might offer a plausible explanation for SNP’s anxiolytic effects.
Displacement techniques in bounded cohomology
Authors: Campagnolo Caterina , Fournier-Facio Francesco , Lodha Yash , Moraschini Marco 
Published: February 2025

Abstract
Several algebraic criteria, reflecting displacement properties of transformation groups, have been used in the past years to prove vanishing of bounded cohomology and stable commutator length. Recently, the authors introduced the property of commuting cyclic conjugates, a new displacement technique that is widely applicable and provides vanishing of the bounded cohomology in all positive degrees and all dual separable coefficients. In this note we consider the most recent along with the by now classical displacement techniques and we study implications among them as well as counterexamples.

Authors: Ozer Gozde , Ozcan H. Nursun , Ardicli Burak , Kutluk Tezer , Oguz Berna , Haliloglu Mithat 
Published: February 2025

Abstract

Background
Hepatoblastoma and hepatocellular carcinoma (HCC) are the most common primary malignant liver tumors in children. Although some characteristic imaging findings have been described in both hepatoblastoma and HCC, it is difficult to distinguish between these two tumors over the 5 years of age.

Objective
To investigate clinical and radiological findings that may help differentiate hepatoblastoma and HCC over 5 years of age.

Materials and methods
From 2007 to 2022, 19 consecutive patients older than 5 years old diagnosed with primary liver malignancy were yielded from our radiology archive retrospectively. Imaging features, age, sex, treatment, and follow-up data were recorded.

Results
A total of 19 patients (16 boys; median age 7.5, min-max 5-17), ten HCCs and nine hepatoblastomas, were included. Serum alpha-fetoprotein (sAFP) values were significantly higher in hepatoblastoma patients (n=9), compared to the HCC (n=10) (P=0.002). Tumor size and PRETEXT stages were higher in hepatoblastoma patients; however, there was no statistical difference (P=0.06). Initial MRI was available for six patients with hepatoblastoma and seven patients with HCC, and there was no difference regarding ADCmin values.

Conclusion
In the differential diagnosis of primary malignant liver tumor in a child older than 5 years of age, higher sAFP level may support the diagnosis of hepatoblastoma rather than HCC.

Perturbations of the endometrial immune microenvironment in endometriosis and adenomyosis: their impact on reproduction and pregnancy
Authors: Shi Jialu , Xu Qianhan , Yu Shuyi , Zhang Tao 
Published: February 2025

Abstract
The impact of endometriosis and adenomyosis on reproduction and pregnancy is significant, with both conditions linked to increased rates of infertility, poor ovarian function in women with endometriosis, and elevated pregnancy complications in those with adenomyosis. However, the underlying mechanisms remain largely unclear. Both conditions share a similar pathophysiological process characterized by the growth of ectopic endometrium, which may originate from the eutopic endometrium. Notably, surgical removal of ectopic lesions does not appear to significantly improve reproductive and pregnancy outcomes, further underscoring the importance of eutopic endometrium in these adverse effects. Emerging evidence indicates substantial differences in endometrial NK cells, macrophages, and T cells, leading to inflammatory responses in women with endometriosis and adenomyosis. These alterations may contribute not only to disease progression but also to defective endometrial receptivity, insufficient angiogenesis remodeling, impaired maternal-fetal immune tolerance, and poor placentation, thereby influencing embryo implantation and pregnancy maintenance. This provides an immunological perspective to explain the higher rates of infertility and pregnancy complications observed in affected women. Therefore, we systematically review the alterations in endometrial immune cells in women with endometriosis and adenomyosis compared to healthy controls, exploring the potential impacts of these changes on reproduction and pregnancy. This review aims to lay the groundwork for future studies on the immunopathogenesis associated with endometriosis and adenomyosis-related reproductive failure and pregnancy complications, shedding lights on the development of immunotherapeutic strategies to mitigate these adverse impacts in affected women.

Abstract

Introduction
Stress perfusion cardiac magnetic resonance (CMR) effectively detects myocardial ischemia. In angina with non-obstructive coronary arteries (ANOCA), visually assessed first-pass perfusion often appears normal. Automated quantitative perfusion (QP) might benefit ANOCA diagnosis, offering absolute quantification of myocardial blood flow (MBF) and myocardial perfusion reserve (MPR).

Aim
We aimed to evaluate the efficacy of QP in detecting ANOCA.

Methods
This study compared fully automated QP CMR in ANOCA patients with age- and sex-matched healthy controls. Participants underwent adenosine stress perfusion CMR, including visual assessment and quantification of MBF and MPR. ANOCA patients underwent coronary function testing to identify vasospasm and/or coronary microvascular dysfunction.

Results
Twenty-four ANOCA patients (83% women, 57 ± 9 years) and 25 healthy controls (80% women, 56 ± 7 years) were included. Visual perfusion assessment did not differ between groups (p = 0.54). Additionally, no differences in resting MBF were observed. However, ANOCA patients had significantly lower global MBF during stress (2.43 ± 0.72 vs 2.99 ± 0.65 ml/g/min, p < 0.01) and a significantly lower global MPR (2.24 ± 0.79 vs 2.68 ± 0.64, p = 0.04) compared to healthy controls. MPR was significantly reduced in the RCA territory in ANOCA patients (2.16 ± 0.71 vs 2.69 ± 0.69, p = 0.01), with no significant differences in other coronary territories. MPR did not significantly differ between ANOCA endotypes.

Conclusions
ANOCA patients display reduced global MPR, suggesting compromised perfusion. Variation in MPR across coronary territories highlights the importance of assessing perfusion in all teritories. These findings are promising and support the use of QP for non-invasive detection of vasomotor dysfunction in ANOCA patients.
