Published: May 2024

Introduction: Menopause is generally considered a stressful experience, with 25% of menopausal women reporting that they experience stress. Using appropriate coping strategies can help reduce stress levels and alleviate other problems in menopausal women. Aims: This study aims to analyze the psychometric properties of two questionnaires designed to measure menopausal stress and coping strategies among menopausal women in Sarawak. Methods: The content validity of this study was assessed by calculating the I-CVI, S-CVI average, S-CVI universal agreement, and CVR. The face validity was also assessed for comparisons within subgroups. A cross-sectional study was conducted in Subis District, Sarawak, involving 221 menopausal women. Participants were selected using a purposive sampling technique and data were collected from face-to-face interviews. Psychometric analysis was performed using SPSS version 28.0. Results: A total of 38 questionnaire items were analyzed by experts for relevance, clarity, simplicity, and ambiguity. After the second modification, the I-CVI, S-CVI/Ave, and CVR for all domains and items were acceptable. Therefore, all items were retained. Face validity was also confimed with an average ICC of 0.979 and a 95% confidence interval between 0.96 and 0.99 (F (9,261a) = 47.996, p < 0.05). Meanwhile, reliability test with a Cronbach’s alpha coefficient of greater than 0.70 indicated a good internal consistency. Conclusion: The questionnaires appeared to be a psychometrically sound instrument for measuring menopausal stress and coping strategies in menopausal women.

An updated method on the injectivity of integral operators related to Riemann Hypothesis
Authors: Adam Dumitru 
Published: May 2024

Abstract

With this article that is a reformulation and improvement of [2] and a continuation of [1], we consider the 165 years old Riemann Hypothesis one of the Clay Inst. 'Millennium Problems', a problem solved.

The Alcantara-Bode (1993) equivalence of the Riemann Hypothesis (RH, 1859) consists in the injectivity of a certain Hilbert-Schmidt integral operator, obtained from Beurling equivalent formulation of RH (1955). Both outstanding equivalences reduced RH to a concrete problem solvable by applied math tools.
In dealing with the injectivity of the linear bounded operators on separable Hilbert spaces, the new theorem introduced and its Corollary could be viewed as an extension of our Injectivity Criteria ([1]) simplifying the investigation.
The result obtained by both methods, the orthogonal projections and restrictions to subspaces of the integral operator, object of the Alcantara-Bode equivalence, has been: RH holds. In other words: the non trivial zeros of the Riemann Zeta function are on the vertical line $\sigma = 1/2$.

Abstract

The IncRNA Malat1 was initially believed to be dispensable for physiology due to the lack of observable phenotypes in Malat1 knockout (KO) mice. However, our study challenges this conclusion. We found that both Malat1 KO and conditional KO mice in the osteoblast lineage exhibit significant osteoporosis. Mechanistically, Malat1 acts as an intrinsic regulator in osteoblasts to promote osteogenesis. Interestingly, Malat1 does not directly affect osteoclastogenesis but inhibits osteoclastogenesis in a non-autonomous manner in vivo via integrating crosstalk between multiple cell types, including osteoblasts, osteoclasts and chondrocytes. Our findings substantiate the existence of a novel remodeling network in which Malat1 serves as a central regulator by binding to β-catenin and functioning through the β-catenin-OPG/Jagged1 pathway in osteoblasts and chondrocytes. In pathological conditions, Malat1 significantly promotes bone regeneration in fracture healing. Bone homeostasis and regeneration are crucial to well-being. Our discoveries establish a previous unrecognized paradigm model of Malat1 function in the skeletal system, providing novel mechanistic insights into how a lncRNA integrates cellular crosstalk and molecular networks to fine tune tissue homeostasis, remodeling and repair.
Triptolide alters intestinal bacteria and ameliorates progression of rheumatoid arthritis in mice
Authors: Pan Xuekang , Jin Zeyuan , Chen Bao , Pan Yuelan , Lu Huigen , Chen Gang 
Published: May 2024

Abstract

Background
Triptolide is a natural compound with immunosuppressive properties. Triptolide has used as a traditional Chinese medicine to treat rheumatoid arthritis (RA). We explore the effects of triptolide on intestinal bacteria and its potential role in alleviating RA progression in mice.
Methods
We randomly assigned thirty-six mice to six of the following groups: Con group, adjuvant-induced arthritis (AIA) group, Htrip group, Mtrip group, Ltrip group and Cele group. We collected tissue and blood samples as well as peritoneal macrophages to assess the effects of triptolide on the response to AIA through physical examinations, ELISA and PCR. We used 16S rDNA gene sequencing to analyze the intestinal flora of AIA mice treated with triptolide. Western blot was used to identify the potential influences on the TLR4/NF-κB pathway, ZO-1 and Occludin.
Results
Our findings showed that triptolide led to a significant reduction in the arthritic index score and paw swelling. It also improved intestinal barrier function by upregulating ZO-1 and Occludin. Furthermore, triptolide treatment caused changes in the intestinal flora by increasing the abundance of beneficial bacteria while decreasing harmful bacteria. Finally, our study demonstrated that triptolide inhibited TLR4/NF-κB, which contributed to its suppressive effects on inflammation.
Conclusion
In summary, our results suggest that triptolide can significantly alleviate the inflammatory response in AIA mice and, at the same time, promote recovery of intestinal barriers. Its mechanism may potentially be mediated by the intestinal flora through the TLR4/NF-κB pathway.

Abstract

Importance: Research on depression and suicidal ideation of sexual minority adults is needed to guide the development of targeted mechanism research and future tailored behavioral interventions.
Objective: To investigate sexual identity differences in depression and suicidal ideation among adults in the US.
Design, setting, and participants: The present cross-sectional study analyzed population-based data from the National Health and Nutrition Examination Survey (2005-2016). Participants included participants aged from 20 to 59 year weighted to represent approximately 788 million US adults.
Exposures: Self-reported sexual identity categorized as heterosexual, gay/lesbian, bisexual, or others.
Main outcomes and measures: The main outcomes were depression and suicidal ideation which defined based on the Patient Health Questionnaire-9.
Results: Our study included 16602 participants (mean age, 39.5 years [95% CI, 39.2-39.9]; 8109 male participants [49.02%]). Male participants who identified as others had higher rate of depression than heterosexual male adults (odds ratio [OR], 3.08; 95% CI [1.06-8.99]). Bisexual male individuals had higher rate of suicidal ideation than heterosexual male participants (OR, 4.53; 95% CI [2.31-8.88]). Compared with heterosexual female participants, bisexual female had higher rate of depression (OR, 2.32; 95% CI [1.68-3.19]) and suicidal ideation (OR, 3.53; 95% CI [2.28-5.48]). There were no significant differences between gay/lesbian and their same sex heterosexual counterparts in depression and suicidal ideation.
Conclusions and relevance: Results of this cross-sectional study suggested that bisexual female participants and others group of male participants had higher rate of depression compared with their counterpart heterosexual participants, furthermore, bisexual male/female participants had higher rate of suicidal ideation than those of heterosexual participants. There is a need for development of tailored interventions to depression symptoms of sexual minority individuals. Future cohort research is needed to examine factors that might contribute to these results among sexual minority individuals.

Published: May 2024

Abstract

The estuarine and tidal flat silt-promoting project and enclosure project have increased the land supply, but the soil salinization is serious, and the research on the driving mechanism of soil salinity and nutrients in reclamation projects is relatively few. To understand the migration law and major factors influencing saline-alkali ions in soil after reclamation projects, six reclamation areas on Hengsha Island from 2003 to 2018 were used as research locations, and 55 investigation sites were set up to monitor and analyze the saline-alkali ions and physical and chemical indexes in soil and water. The results showed that the reclamation areas in the Yangtze River estuary were all chloride-type saline alkali areas. Among them, the saline-alkali ions in the soil in the reclamation area were significantly higher than those in the old reclamation area within five years. Na+, K+ and Cl- were higher in areas with low moisture content, while Ca2+, SO42- and HCO3- were higher in soil with vegetation. The soil salt ions and physical and chemical indexes in the reclamation area appeared stratified. Correlation analysis showed that organic matter, moisture content and phosphorus were the major factors affecting soil salt ions and pH in the reclamation area.

Abstract

The high concentrations of particulate matter (PM) in the atmosphere have adverse effects on both the environment and human health, as well as on urban and faunal biodiversity. Short-term events, such as the burning of fireworks, attributable to human activity, result in a significant and rapid increase in PM concentration levels within the atmosphere. We present findings derived from observations made using low-cost PM sensors deployed as part of the Environmental Monitoring Network in Querétaro, Mexico. These sensors utilize the Environmental Geo Monitoring Stations (EMGA) device, developed by the Institute of Geosciences at UNAM. The observation period spanned from December 10, 2023, to January 10, 2024, encompassed the Christmas and New Year holidays, and focused on PM2.5 concentrations, and a comparison with a similar period from February 10, 2024, to March 10, 2024, considered a typical activity period in the area. The results reveal a substantial increase in PM2.5 concentrations over time and spatial distribution during this period, with notable increases observed during the festive season. Specifically, prolonged periods exceeding up to 6 hours were noted on festivities dates. This research offers insight into the effects, trends, and spatial-temporal distribution of pollutants within the city of Queretaro, which may be used as a reference for other cities around the world. Furthermore, a comparison between PM2.5 data recorded by the EMGA devices and infrasound data was conducted complementarity to explore potential correlations between these two types of data.

Abstract

In aquatic environments, mercury (Hg) bioaccumulation rates tend to reflect the organism’s position in the food web – the larger the rate, the higher their position. Here we present the first attempt to reconstruct such web for the Romualdo Formation of the Araripe Basin (Northeastern Brazil), based on Hg bioaccumulation of its fossil record; the aim is to understand possible trophic relationships between vertebrate/invertebrate species inhabiting its paleoenvironments. Observed ratios between Hg concentrations [Hg] in fossils and their surrounding concretions ([Hg]sample) suggest bioaccumulation increases with the change in feeding habits and size of the fish taxa analysed, being lowest in Rhacolepis to a maximum peak in the large predator genera Cladocyclus and Calamopleurus. Feeding habits of Vinctifer were also reviewed, and the genus was reinterpreted from filter feeder to mesopredator; durophage bottom-feeding taxa recorded values compatible with their predicted feeding habits. Low [Hg]sample ratios were observed in ornithocheiriform pterosaurs, suggesting it a mesopredators specialized in the smaller fish species, while Thalassodrominae presented intermediate to high [Hg]sample, pointing out to a unique trophic role as a terrestrial opportunistic generalist, ranging from predator to scavenger.
