Published: September 2024

Objective: To evaluate the incorporation of chayotextle (Sechium edule) root starch and erythritol on the physicochemical quality of a yogurt enriched with inulin.
Design/methodology/approach: The following treatments were established: T1: Erythritol 2.1%; T2: Starch 1% + Erythritol 2.1%; T3: Sugar 1.5% + Erythritol 1.05%; T4: Starch 1% + Sugar 1.5% + Erythritol 1.05%; T5: Sugar 3% and T6: Starch 1% + Sugar 3%. The variables nutritional content, pH, total soluble solids, syneresis, and sensorial quality were determined through CATA.
Results: The incorporation of chayotextle starch to yogurt favored an increase in the content of non-fatty solids and a decrease in syneresis, while the use of erythritol as sugar substitute decreased the caloric content and of non-fatty solids and increased the pH and syneresis, contrary to the use of sugar. Enrichening all the formulations with 5% of inulin favored the stability and increased the dietary fiber in all the treatments. Sensorially, the chayotextle starch combined with sugar favored a greater sensorial acceptance of the yogurt.
Limitations on study/implications: To evaluate the texture profile of the yogurt, as well as the use of other stabilizers such as potato, corn, yucca and gums like xanthan, arabic or even carboxymethyl cellulose which are commercial.
Findings/conclusions: The addition of erythritol does not substitute sugar as a sweetener from the sensorial point of view. However, nutritionally, it reduces the caloric content in 57%. Inulin favors the dietary fiber content, while the chayotextle starch together with sugar preserved the physicochemical and sensorial characteristics of yogurt
Which Measures can Reduce Parental Driving to Sport Activities?
Authors: Lunke Erik Bjørnson , Nordbakke Susanne
Published: September 2024

We conducted a survey to investigate how parents evaluate the effect (on their own behaviour) of five measures to reduce driving of children to sport activities in the municipality of Bærum, Norway. We find that parents’ evaluation of the effect varies for each measure, where the largest (perceived) effect is found in providing buses to activities. Moreover, we find large disparities in potential effect between different sports. Carpooling and walking/cycling groups are more relevant for soccer and handball, activities that take place in children’s local area. For skiing and ice-skating, we find a stronger effect in providing the possibility to store gear at the activity location. The disparities in potential effects among type of activities are probably linked to differences of locations of activities or in amount of gear that has to be brought along.

Malaria due to Plasmodium species is an existential problem and a major disease in many developing countries. The emergence of drug-resistant parasites and the limited availability of effective treatments present major challenges in combating this disease. Thus, searching for more potent antimalarial agents, especially from natural sources, has become urgent and imperative. This study investigates the anti-plasmodial properties of the ethanolic crude extracts of Adansonia digitata (stem bark), Morinda citrifolia (leaves), and Tamarindus indica (leaves) using standard methods. The crude plant extracts were obtained using the maceration technique using 70% ethanol. The in vitro anti-plasmodial activities of the crude extracts were assessed using the Plasmodium lactate dehydrogenase (pLDH) assay against asexual stages of clinical isolates of P. falciparum maintained at 5% haematocrit (human type O+ red blood cells) in complete RPMI-1640 medium. The crude ethanolic extracts of T. indica exhibited a significantly higher (p < 0.05) in vitro anti-plasmodial activity with an IC50 value of 5.86μg/mL, followed by A. digitata (IC50 = 30.22μg/mL,) and M. citrifolia (IC50 = 31.85μg/mL). The findings in this study indicated that the crude extracts tested showed potential for anti-plasmodial activities that could be harnessed for developing novel anti-plasmodial agents.

Authors: Argun Selim , Eskin Ümit
Published: September 2024

İslam tarihinde muhalifler ve düzeni bozanlar çeşitli şekillerde cezalandırılmıştır. Bu cezalardan biri de sürgün olmuştur. Sürgün amacıyla kullanılan yerlerden biri de Arapların muhayyilesinde çetin şartları ve uzaklığıyla yer edinen ve şiirlere dahi konu olan Dehlek adaları olmuştur. Doğu Afrika’da Masavva limanı açıklarında yer alan Dehlek adalar topluluğuna, en büyükleri olan Dehlek el-Kebîr adını vermiştir. Bu adalar stratejik konumları sebebiyle tarih boyunca askerî, siyasî ve ticarî açıdan önemli bir yere sahip olmuştur. Arapların İslâm öncesinde ticaret sebebiyle bildiği anlaşılan ada ve civarı, Habeşistan’a ilk hicretler ve Râşid Halifeler döneminde bölgeye düzenlenen akınlarla daha iyi tanınmaya başlamıştır. Emevîler döneminde gerek Kızıldeniz’in ticarî güvenliğini sağlamak gerekse Doğu Afrika’ya yönelik askerî hamleler çerçevesinde Dehlek adası ele geçirilmiştir. Böylece Müslümanların hakimiyetine giren ada, Emevîler ve Abbâsîler döneminde çeşitli sebeplerle farklı sınıflardan kişi ve grupların sürgün yeri olarak kullanılmıştır. Makalede bunlar arasında yer alan şair Ahvas el-Ensârî, kadı Irâk b. Mâlik el-Medenî, şair Ömer b. Ebî Rebîa el-Mahzûmî, bazı Kaderiyye mensupları ve Abbâsî valisi Abdülcebbâr b. Abdurrahman el-Ezdî’nin ailesinden bahsedilecektir. Emevî valisi Yezîd b. Mühelleb el-Ezdî ve Ali b. Abdullah el-Abbâsî ise adaya sürgün kararı çıkarıldığı halde sürgünlerinden vazgeçilen önemli kişiler arasında yer alır. Ayrıca bazı kaynaklarda Dehlek’e sürgün edildiği rivayet edilen kimi kimseler de zikredilir. Ancak bunların sürgün edilme ihtimalleri mümkün olmayıp bahse konu rivayetler zayıf ve sorunludur. Bu çalışmada, kaynaklardaki kısıtlı bilgiler ışığında adanın İslâm hakimiyetine girişi ve sürgün yeri olma vasfıyla ilgili rivayetler değerlendirilecektir.
Genetic population structure and demographic history of the sailfin sandfish Arctoscopus japonicus associated with sea level changes during the Last Glacial Maximum
Authors: Kurihara H , Ikeda M
Published: September 2024

Understanding the genetic population structure and demographic history of a fishery resource species is important for resource management that considers the viability and evolutionary potential of the species. The sailfin sandfish Arctoscopus japonicus is an important resource in Japan. Its population structure has been investigated in previous studies, but a mismatch between morphometric and population genetic analysis was observed. We investigated whether this mismatch could be attributed to the detection sensitivity of DNA markers by analyzing nuclear microsatellite loci. We also estimated the formation process of the population structure through demographic analysis based on mitochondrial DNA. Our analysis revealed the presence of formerly undetected subtle genetic differences between local populations, which were consistent with the findings of the previous morphometric study. Demographic analysis suggests that the most diverged populations of the Pacific Ocean and Sea of Japan differentiated as a result of vicariance during the last glacial period. We also found that the Sea of Okhotsk population may have originated from admixture between Pacific Ocean and Sea of Japan individuals. These results provide new insights into the population structure of the species, which are essential for resource management.

Вияв християнської моралі у «Психомахії» Пруденція
Authors: Пуховець Дмитро
Published: September 2024

Метою статті є дослідження поеми «Психомахія» Пруденція у контексті релігійної та суспільно-політичної атмосфери Римської імперії на рубежі кінця IV – початку V ст. від Р.Х. Після прийняття антиязичницьких законів імператора Феодосія І на початку 390-х років християнство, нібито, остаточно перемогло старі культи. Але насправді християни відчували необхідність продовжувати боротьбу за свідомість язичників і своїх поверхових одновірців. Іншою проблемою були єресі – вчення Арія, Фотіна, Присцилліана, які підривали єдність християнської общини зсередини. «Психомахія» є алегоричною поемою про битву чеснот і вад у душі людини. Метою її написання було прославляння християнської моралі та світогляду, полемічна боротьба проти язичництва та єресей. Твір прославляє християнську етику, рясніє відсиланнями на Біблійну традицію. У той же час щодо форми поеми Пруденцій багато в чому орієнтувався на класичну традицію, передусім «Енеїду» Вергілія. Поєднання унікального жанру, класичної традиції та християнського наповнення робить «Психомахію» унікальною пам’яткою доби переходу від античності до середньовіччя, яка допомагає краще зрозуміти сутність цієї доби та цього переходу.

Navigating pathways to automated personality prediction: a comparative study of small and medium language models
Authors: Habib Fatima , Ali Zeeshan , Azam Akbar , Kamran Komal , Pasha Fahad Mansoor
Published: September 2024

Introduction

Recent advancements in Natural Language Processing (NLP) and widely available social media data have made it possible to predict human personalities in various computational applications. In this context, pre-trained Large Language Models (LLMs) have gained recognition for their exceptional performance in NLP benchmarks. However, these models require substantial computational resources, escalating their carbon and water footprint. Consequently, a shift toward more computationally efficient smaller models is observed.

Methods

This study compares a small model ALBERT (11.8M parameters) with a larger model, RoBERTa (125M parameters) in predicting big five personality traits. It utilizes the PANDORA dataset comprising Reddit comments, processing them on a Tesla P100-PCIE-16GB GPU. The study customized both models to support multi-output regression and added two linear layers for fine-grained regression analysis.

Results

Results are evaluated on Mean Squared Error (MSE) and Root Mean Squared Error (RMSE), considering the computational resources consumed during training. While ALBERT consumed lower levels of system memory with lower heat emission, it took higher computation time compared to RoBERTa. The study produced comparable levels of MSE, RMSE, and training loss reduction.

Discussion

This highlights the influence of training data quality on the model's performance, outweighing the significance of model size. Theoretical and practical implications are also discussed.
Analysis of anisotropy anomalies identification in apparent resistivity observation

Published: September 2024

Since 1966, China has been using apparent resistivity observation to forecast strong aftershocks of the Xingtai earthquake. Retrospective studies of subsequent strong earthquakes have shown that anomalies in apparent resistivity observation before earthquakes usually exhibit anisotropic characteristics. In addition to the anisotropic changes in apparent resistivity before earthquakes, factors such as subway operation near the observation area, metal pipeline networks, and changes in water levels have also been found to cause anisotropic changes. These factors are called environmental interference factors. Therefore, distinguishing between anisotropic changes before earthquakes and anisotropic changes caused by interference and eliminating the effects of interference is crucial for using apparent resistivity observations for forecasting. Taking the observation of Hefei seismic station in Anhui Province as an example, a model is constructed using the finite element method to try to establish a method for analyzing anisotropy in apparent resistivity before earthquakes, and the data from other provincial stations are used for verification. In the modeling process, the influence coefficient is a measure of the relationship between the variation in apparent resistivity and the changes in the medium of the measurement area. The following results are obtained by calculating the influence coefficient using the finite element method: the influence coefficient between the power supply electrode and the measuring electrode of the apparent resistivity observation is negative, and the rest are positive, and the distribution of the influence coefficient shows obvious symmetry, with the axis of symmetry being the line connecting the electrodes and its midline, and the absolute value of the influence coefficient is inversely proportional to the distance from the electrodes. In addition, according to the constructed finite element model, the amplitude of anisotropic changes caused by interference can be quantitatively calculated. Given that interference is ubiquitous in various regions of the world, this study can provide a reference for international earthquake forecasters to quantitatively remove environmental interference in anisotropy. Moreover, when building apparent resistivity stations in seismic areas for earthquake prediction, it is best to avoid areas with larger local influence coefficients to ensure that the anomalous data before the earthquake is true and reliable.

Published: September 2024

The Early Bartonian Reneiche/Siouf member is one of the primary conventional carbonate oil/gas reservoirs to be assessed in Tunisia that demands detailed evaluation. Accurate zonation and modeling of this reservoir require an integrated approach combining surface and subsurface studies. This research focuses on the depositional, diagenetic, and stratigraphic factors affecting reservoir quality and porosity within the Reneiche/Siouf member, utilizing an integrated surface-subsurface analysis. The primary aim is to understand the reservoir zonation of the Reineche Member near Kerkennah archipelago (eastern Tunisian offshore) and its lateral equivalents in central Tunisia the Siouf Member (outcrop analogue). Gamma-ray and sonic logs from the Reineche Member in the southern and southeastern Pelagian Platform (Tunisian offshore) identify three distinct limestone units (A, C, and E). These units transition into a single mud-dominated limestone unit (C) to the east and northeast of the Kerkennah archipelago. In contrast, the western Pelagian Platform (onshore) and Central Tunisia present a different stratigraphy for the Reineche/Siouf Member, comprising two limestone units: the Lower Reneiche Limestone (LRL) and the Upper Reneiche Limestone (URL), corresponding to Units C and E, respectively, separated by the Upper Reneiche Shale (URS) unit. Reservoir porosity and permeability analyses of the outcrop analogs reveal hybrid pore types (depositional and diagenetic), including intragranular, biomouldic, and vuggy pores, resulting from significant dissolution of large bioclasts. In the northern Gulf of Gabes, the Nummulite barrier of the Reineche Member (SW of the Kerkennah archipelago) demonstrates substantial reservoir quality improvement, with porosity reaching up to 30% in Unit C, attributed to intense dissolution, dolomitization (intercrystalline porosity), and fracturing. Diagenetic processes observed in the Siouf Member (Central Tunisia) differ from those in the Reineche Limestone Member (Pelagian Platform). In the Reineche Member, CO2-rich fluids entering through faults and fissures during deep burial diagenesis drive dissolution and dolomitization. Conversely, in the Siouf Member, these processes occur due to short subaerial exposures during meteoric to shallow-burial diagenesis. A key outcome of our study is the comparison between Central Tunisia and the eastern Tunisian offshore, highlighting local tectonic control on reservoir thickness and identifying three upward-thickening sequences in the Siouf Member outcrop. This research is crucial for understanding the Gulf of Gabes and Libyan offshore nummulitic Eocene reservoirs, emphasizing the role of tectonics and sea level changes in shaping reservoir characteristics.

Published: September 2024

As the integration of high-proportion renewable energy into the grid increases, the intermittency and uncertainty of renewable energy output significantly affect the safe and stable operation of the power system. Combining utility-scale energy storage technology with renewable coordination is one of the methods to address these issues. Compressed air energy storage (CAES) has garnered extensive attention due to its large capacity, long operational life, and clean, low-carbon advantages. Given the poor compressibility of air and its high critical point, using carbon dioxide as the working fluid in utility-scale energy storage systems can achieve higher energy storage density and cycle efficiency. Accordingly, this paper focuses on the study of utility-scale energy storage system modeling and scheduling methods considering carbon dioxide energy storage. It investigates Compressed Carbon Dioxide Energy Storage (CCES) systems, analyzes the operational framework of typical CCES systems, and sequentially establishes models for the energy storage process, energy release process, hot water tank operation, and gas storage tank operation. Based on this, it explores power system optimization dispatch methods considering CCES, incorporating the established models into an optimization dispatch model for power systems with high wind power penetration. Within the framework of a safe constraint unit commitment study, using the IEEE-30 nodes model, the effectiveness of the established models is validated. The case study results confirm the role of CCES in enhancing the absorption rate of renewable coordination. Moreover, under the same storage conditions, compared to, CCES offers greater charging and discharging power and higher energy storage density.
Effective communication in an emerging CCS industry – an application of the SPE SRMS to convey contingencies, uncertainties, commerciality, and progress to project approval
Authors: Chernik Paul S. , Caniggia Matteo , Mitchell Ellen
Published: September 2024

At COP28, Carbon Capture, Utilization, and Storage was declared a removal technology whose application must be accelerated. In 2017, the Society of Petroleum Engineers (SPE) published the CO2 Storage Resource Management System (SRMS) as a framework for stakeholder communication. The SRMS guidelines were designed to support the creation of reports that inform readers regarding the contingencies that must be overcome to obtain project approval, uncertainty in the mass of CO2 that can be stored, and the commerciality of the project. However, working examples where the SRMS has been used to communicate project status in the public domain are limited. In 2023, the authors of this paper referred to the SRMS as the standard for completing an expert report, termed a Competent Persons Report (CPR), for the Viking Carbon Capture and Storage (CCS) development in the United Kingdom. During the application of the SRMS framework, challenges were identified in conveying the progress made by the project proponent in identifying and addressing technical risks. This paper describes innovations developed to supplement the SRMS guidelines and improve communication with stakeholders. First, a flowchart was developed to explain a vital interpretation of the SRMS. Next, a defined framework of technical milestones was designed to assess the maturity of a given technical topic within the SRMS. This framework was combined with radial data visualization. The combination allowed multiple storage sites to be compared simultaneously and allowed stakeholders to quickly identify the maturity of technical analysis for any given site. We conclude that improving the consistency and clarity of CCS reporting to stakeholders can help build trust in this emerging industry.
Supply chain carbon abatement under different power structures: impact of consumers’ low-carbon preference and carbon tax policy
Authors: Li Guozhi , Jiang Mengying , Yuan Yidan , Chen Xunuo , Fu Dandan
Published: September 2024

Supply chain carbon abatement is an important way to promote low-carbon transformation of the social economy and address global climate change. This paper analyzes the issue of supply chain carbon abatement under different power structures, as well as the effect of consumers’ low-carbon preference and carbon tax rate on the optimal decisions. This paper constructs five different models, namely ML-NO model, ML-CS model, RL-NO model, RL-CS model and VI model. The research finds that VI model is the most ideal model for promoting supply chain carbon abatement. The optimal abatement efforts, market demand, and total profits in the VI model are all the largest among the five models. Whether the supply chain leader is the manufacturer or the retailer, cost sharing contract can enhance optimal abatement efforts, market demand, and profits of both parties. In any model, the leader in Supply chain earns higher profits than the follower. When consumers’ low-carbon preference increases, the optimal abatement efforts, market demand, and profits of both parties will all increase, and the growth rate is gradually accelerating. For the manufacturer with high carbon emissions, when the carbon tax rate increases, the optimal abatement efforts first increase and then decrease. For the manufacturer with low carbon emissions, when the carbon tax rate increases, the optimal abatement efforts will also increase.

Published: September 2024

Introduction

Woodchips as a source of particulate organic carbon (POC) are proposed as a nature-based solution to enhance nutrient uptake and retention in agricultural streams. However, the effective implementation of woodchips for nutrient removal in streams requires an advanced understanding of their potential and limits, considering their performance under various environmental conditions. This study tested the efficiency of woodchips on the uptake of soluble reactive phosphorus (SRP) and ammonium (N-NH4) across different experimental scales and complexity. We investigated whether the presence of woodchips can increase SRP and N-NH4 uptake in laboratory flumes under controlled conditions, outdoor flumes under semi-controlled conditions, and agricultural streams. Additionally, we examined how the effects of woodchips will change over time via a 6-week incubation in the outdoor flumes.

Methods

The woodchips were pre-colonized for four weeks to allow the growth of biofilms. We performed short-term nutrient additions without (control) and with (treatment) woodchips in all three experimental setups. Uptake parameters were determined via concentration changes over time in the laboratory flumes and concentration changes over travel distance in the outdoor flumes and the stream channels. The effects of woodchips on SRP and N-NH4 uptake rates were analyzed using an effect size model.

Results

We found positive effects of woodchips on nutrient uptake only in the laboratory flumes but no or even negative effects in the outdoor flumes and the agricultural streams. Over the 6-week incubation in the outdoor flumes, we did not observe significant changes in the effects of woodchips on nutrient uptake.

Discussion

These findings highlight that considering experimental scales and influencing environmental conditions is crucial when testing the application of woodchips as nature-based solutions to mitigate nutrient loads in agricultural streams.

Published: September 2024

Jilin Province is a crucial region of interest for agricultural and forestry development in China. The deterioration of its ecological environment could have a severe impact on agricultural production and ecological conservation. A systematic assessment of ecological environment quality in Jilin Province is essential for its sustainable development. In this study, we utilized Landsat data from 1990 to 2020 (every 5 years) to construct the Remote Sensing Ecological Index (RSEI) for Jilin Province. We applied the Sen’s slope estimator and the Mann-Kendall trend test to examine the spatiotemporal changes in ecological environment quality over a 30-year period. Additionally, we employed the Geo-detector to explore the socioeconomic and natural factors influencing ecological environment quality. The results revealed: 1) From 1990 to 2020, the average RSEI index in Jilin Province ranged from 0.586 to 0.699, indicating overall good ecological environment quality. Spatially, ecological environment quality gradually declined from east to west. 2) The RSEI in Jilin Province exhibited an initial increase, followed by a decrease, and then another increase trend. This improvement can be attributed to the implementation of government policies, which reversed the expansion of saline-alkali land. Ecological environment quality significantly improved in the western region of Jilin Province over the 30-year period. 3) Socioeconomic and natural factors both influence ecological environment quality in Jilin Province. Among these factors, vegetation coverage has the most significant impact on the ecological environment quality in the study area, with natural factors exerting a more significant influence than socioeconomic factors. Our research can provide relevant data support for policy-making in Jilin Province.

Emerging contaminants (ECs), such as polyfluorinated compounds, antibiotics, microplastics, and nonylphenol, continue to challenge environmental management practices due to their persistence and bioaccumulation potential. This review articulates the critical pathways and environmental risks posed by these contaminants, setting the stage for an in-depth exploration of innovative removal technologies. We spotlight groundbreaking methods that are reshaping the landscape of ECs remediation: membrane filtration technology, constructed wetlands, adsorptive materials, algae-based systems, biological treatments, and advanced oxidation processes. Each method is evaluated for its efficacy in removing ECs, with particular emphasis on sustainability and economic viability. Our findings reveal that integrating these technologies can significantly enhance removal efficiency, offering new directions for environmental policy and practical applications. This article positions these advanced removal technologies at the forefront of the fight against ECs, advocating for their broader adoption to safeguard environmental and public health.
Causal relationship, shared genes between rheumatoid arthritis and pulp and periapical disease: evidence from GWAS and transcriptome data
Authors: Wu Huili , Wang Lijuan , Qiu Chenjie
Published: September 2024

Objective

Patients with rheumatoid arthritis (RA) have an increased risk of developing pulp and periapical disease (PAP), but the causal relationship and shared genetic factors between these conditions have not been explored. This study aimed to investigate the bidirectional causal relationship between RA and PAP and to analyze shared genes and pathogenic pathways.

Methods

We utilized GWAS data from the IEU Open GWAS Project and employed five Mendelian randomization methods (MR Egger, weighted median, inverse variance weighted, simple mode, and weighted mode) to investigate the bidirectional causal relationship between RA and PAP. Transcriptome data for RA and irreversible pulpitis (IRP) were obtained from the GEO database. Hub genes were identified through differential analysis, CytoHubba, machine learning (ML), and other methods. The immune infiltration of both diseases was analyzed using the ssGSEA method. Finally, we constructed a regulatory network for miRNAs, transcription factors, chemicals, diseases, and RNA-binding proteins based on the identified hub genes.

Results

RA was significantly associated with an increased risk of PAP (OR = 1.1284, 95% CI 1.0674-1.1929, p < 0.001). However, there was insufficient evidence to support the hypothesis that PAP increased the risk of RA. Integrating datasets and differential analysis identified 84 shared genes primarily involved in immune and inflammatory pathways, including the IL-17 signaling pathway, Th17 cell differentiation, and TNF signaling pathway. Using CytoHubba and three ML methods, we identified three hub genes (HLA-DRA, ITGAX, and PTPRC) that are significantly correlated and valuable for diagnosing RA and IRP. We then constructed a comprehensive regulatory network using the miRDB, miRWalk, ChipBase, hTFtarget, CTD, MalaCards, DisGeNET, and ENCORI databases.

Conclusion

RA may increase the risk of PAP. The three key genes, HLA-DRA, ITGAX, and PTPRC, have significant diagnostic value for both RA and IRP.

Introduction

The programmed cell death (PCD) plays a key role in the development and progression of lung adenocarcinoma. In addition, immune-related genes also play a crucial role in cancer progression and patient prognosis. However, further studies are needed to investigate the prognostic significance of the interaction between immune-related genes and cell death in LUAD.

Methods

In this study, 10 clustering algorithms were applied to perform molecular typing based on cell death-related genes, immune-related genes, methylation data and somatic mutation data. And a powerful computational framework was used to investigate the relationship between immune genes and cell death patterns in LUAD patients. A total of 10 commonly used machine learning algorithms were collected and subsequently combined into 101 unique combinations, and we constructed an immune-associated programmed cell death model (PIGRS) using the machine learning model that exhibited the best performance. Finally, based on a series of in vitro experiments used to explore the role of PSME3 in LUAD.

Results

We used 10 clustering algorithms and multi-omics data to categorize TCGA-LUAD patients into three subtypes. patients with the CS3 subtype had the best prognosis, whereas patients with the CS1 and CS2 subtypes had a poorer prognosis. PIGRS, a combination of 15 high-impact genes, showed strong prognostic performance for LUAD patients. PIGRS has a very strong prognostic efficacy compared to our collection. In conclusion, we found that PSME3 has been little studied in lung adenocarcinoma and may be a novel prognostic factor in lung adenocarcinoma.

Discussion

Three LUAD subtypes with different molecular features and clinical significance were successfully identified by bioinformatic analysis, and PIGRS was constructed using a powerful machine learning framework. and investigated PSME3, which may affect apoptosis in lung adenocarcinoma cells through the PI3K/AKT/Bcl-2 signaling pathway.

Authors: Xie Weimin , Xu Zhengmei
Published: September 2024

Cervical cancer is one of the most malignant gynaecological tumors characterised with the aggressive behaviour of the tumor cells. In spite of the development of different strategies for the treatment of cervical cancer, the tumor cells have developed resistance to conventional therapeutics. On the other hand, nanoparticles have been recently applied for the treatment of human cancers through delivery of drugs and facilitate tumor suppression. The stimuli-sensitive nanostructures can improve the release of therapeutics at the tumor site. In the present review, the nanostructures for the treatment of cervical cancer are discussed. Nanostructures can deliver both chemotherapy drugs and natural compounds to increase anti-cancer activity and prevent drug resistance in cervical tumor. Moreover, the genetic tools such as siRNA can be delivered by nanoparticles to enhance their accumulation at tumor site. In order to enhance selectivity, the stimuli-responsive nanoparticles such as pH- and redox-responsive nanocarriers have been developed to suppress cervical tumor. Moreover, nanoparticles can induce photo-thermal and photodynamic therapy to accelerate cell death in cervical tumor. In addition, nanobiotechnology demonstrates tremendous potential in the treatment of cervical cancer, especially in the context of tumor immunotherapy. Overall, metal-, carbon-, lipid- and polymer-based nanostructures have been utilized in cervical cancer therapy. Finally, hydrogels have been developed as novel kinds of carriers to encapsulate therapeutics and improve anti-cancer activity.
Glacial rock flour increases photosynthesis and biomass of natural phytoplankton communities in subtropical surface waters: a potential means of action for marine CO2 removal

Photosynthesis by phytoplankton reduces partial pressure of CO2 at the surface of the ocean and is therefore a potential means of action for a marine CO2 removal technology. Here we study how glacial rock flour may influence photosynthesis in the open ocean. Glacial rock flour is a fine-grained silicate mineral from the bedrock grinded by the Greenland Ice Sheet and enters the ocean via fjords and coastal waters. It is therefore a natural source of nutrients and trace metals to the ocean. It is easily accessible in large quantities and could be a suitable source for large-scale CO2 removal. The impact of suspended glacial rock flour was analyzed through 14 incubation experiments with natural phytoplankton communities sampled in the subtropical Atlantic. A significant increase in photosynthesis was found in 12 experiments where variable fluorescence Fv/Fm increased 12% and the average concentration of chlorophyll a increased significantly in comparison with control treatments during a 6-day period. Incubations with glacial rock flour showed a significant uptake of phosphorus whereas the average concentrations of silicate and dissolved inorganic nitrogen increased. Nutrient changes could be explained by increasing phytoplankton and microbial biomass, remineralization of organic matter, and weathering (mobilization) of glacial rock flour. These short time experiments indicated that trace metals from glacial rock flour stimulated phytoplankton growth. Thus, glacial rock flour has the potential to increase photosynthesis and phytoplankton growth, and therefore may be a potential means of action for marine CO2 removal.

Mesoscale eddies cause deviations from the background physical and biogeochemical states of the oligotrophic oceans, but how these perturbations manifest in microbial ecosystem functioning, such as community macromolecular composition or carbon export, remains poorly characterized. We present comparative lipidomes from communities entrained in two eddies of opposite polarities (cyclone–anticyclone) in the North Pacific Subtropical Gyre (NPSG). A previous work on this two-eddy system has shown differences in particulate inorganic carbon (PIC) and biogenic silica sinking fluxes between the two eddies despite comparable total organic carbon fluxes. We measured the striking differences between the lipidomes of suspended and sinking particles that indicate taxon-specific responses to mesoscale perturbations. Specifically, cyanobacteria did not appear to respond to increased concentrations of phosphorus in the subsurface of the cyclonic eddy, while eukaryotic microbes exhibit P-stress relief as reflected in their lipid signatures. Furthermore, we found that two classes of lipids drive differences between suspended and sinking material: sinking particles are comparatively enriched in phosphatidylcholine (PC, a membrane-associated lipid) and triacylglycerol (TAG, an energy storage lipid). We observed significantly greater export of TAGs from the cyclonic eddy as compared to the anticyclone and found that this flux is strongly correlated with the concentration of ballast minerals (PIC and biogenic silica). This increased export of TAGs from the cyclone, but not the anticyclone, suggests that cyclonic eddy perturbations may be a mechanism for the delivery of energy-rich organic material below the euphotic zone.
