A field experiment was undertaken in the post-Rabi season of 2019-2020 to reveal the response of greengram (Vigna radiata L.) to seed dressing and seed priming with nano molybdenum trioxide (MoO3). The experiment was laid out in randomized block design (RBD) consisting of 10 different treatments i.e., M0 (no seed treatment with Mo); M1 (seed dressing with Sodium molybdate @ 400 ppm); M2, M3, M4, and M5 (seed dressing with nano Molybdenum trioxide-MoO3 @ 50, 100, 200 and 400 ppm, respectively); and M6, M7, M8 and M9 (seed priming with nano MoO3 @ 50, 100, 200 and 400 ppm, respectively). Inoculation of greengram seeds cv. Shreya (IPM 2-14) with Rhizobium sps. was undertaken in all treatments as per the recommended practice, except in M0 (control). The MoO3 nanoparticles (NPs) synthesized from Ammonium molybdate through calcination at 600 0C for 5 hours indicated globular-shaped NPs of 68.55 nm in TEM and XRD. Nanopriming with MoO3 @ 200 ppm (M8) was most promising in recording significantly superior growth and yield attributing parameters and yield, whereas Mo (control) produced the least. Crop height, number of branches, root length, shoot dry matter, pods/plant and seeds/plant and root nodulation at harvest in M8 were 39.4% and 22.6%; 39% and 5.6%; 23% and 9.3%; 43.9%, and 16.3%; 28.2% and 5.3%; 28.1% and 0.8%, and 73.3% and 36.5% higher than M0 (control) and M1 (farmers’ practice), respectively. Superior growth and yield attributing characters in M8 treatment produced the highest grain and stover yield of 0.88 and 3.74 t/ ha that was 32.53% and 8.37%, and 35.5% and 14.7% higher than M0 (control) and M1 (farmers’ practice), respectively. Seed priming with nano MoO3 @ 400 ppm (M9) and seed dressing with nano MoO3 @ 400 ppm (M5) were of second and third order in recording grain and stover yield but M0 recorded the lowest among all the treatments.

The role of adaptive librarians affects the implementation of Information and Communication Technology (ICT), especially in governmental libraries. It adjusts the competencies and abilities needed by librarians. Therefore, librarians are required to rebuild and improve their skills related to ICT. In Indonesia, Standar Kompetensi Kerja Nasional Indonesia (SKKNI) 2019 is used as a national education & training framework for librarians. To explore this theme according to SKKNI, a sequential exploratory research was conducted with contributions from librarians and/or library staff who work in governmental libraries across the Republic of Indonesia. Through in-depth interviews, focused group discussions with 28 librarians from 14 governmental libraries in Jabodetabek, also an online survey (74 respondents), the researchers were able to gain a pattern that showed the tendency of higher ability level in the competency units related to ICT utilization in the library than the competency units in developing library information systems. The unit of competence with the highest mean score is the unit of competence related to multimedia production, including the management of the library’s social media content. Aligning with this result, National Library as the central supervisor for the librarian needs to collaborate with related stakeholders, especially in accommodating competence development efforts to build a national digital ecosystem. Those efforts include the formulation of continuing development program -gradual education and training program. Through this collaboration between various stakeholders, the development of librarian competencies specifically within governmental libraries can be carried out efficiently, following the real needs in the field.

Animals that have the potential to produce meat that can be developed are Bali cattle. Unlike imported cattle, Bali cattle are superior because they can withstand all weather and adapt easily. Research on Bali cattle is quite a lot. However, we do not yet know the direction and status of the research. For this reason, it is necessary to conduct a study of the research that has been carried out. The research data comes from secondary data, namely scientific journal articles and proceedings articles. Data publication year is limited to June 2023. Data is tracked using Publish or Perish software. The data obtained was processed using Zotero, MS-Excel and VOSviewer software. There were 983 studies found, with the highest number of animal feed and nutrition, with 190 studies (19.31%). The most productive researcher is Jakaria (49 titles). The number of Bali cattle studies each year varies greatly with the highest number occurring in 2020 (169 studies). It is known that the authorship pattern of the Bali cattle research results article is in accordance with Lotka's law with an exponent value of 2.1 and a constant value of 66%. The researcher collaboration map and research topic map were successfully created using VOSviewer. The degree of author collaboration was 0.91. Related research including animal waste, animal welfare, animal farm and conservation can still be developed because there are not many researches in these fields.

Voglerin Hoosiannan vakiintuminen adventin suosikkilauluksi 1800-luvun Suomessa ja Inkerinmaalla
Authors: Korkalainen Samuli
Published: December 2023

Saksalaisen Georg Joseph Voglerin 1700-luvun lopun Tukholmassa säveltämän Hoosianna-hymnin suosion vuoksi ensimmäinen adventtisunnuntai on tänäkin päivänä yksi suosituimpia juhlapyhiä Suomessa. Alun perin palmusunnuntain kuorolauluksi tarkoitettu sävellys vakiintui 1800-luvulla Ruotsissa, Suomessa ja Inkerinmaalla osaksi adventinviettoa. Alkuun sitä esittivät Suomen kirkoissa koululaiset, mutta vähitellen alettiin varta vasten koota kuoroja sen laulamiseksi. Tapa lähti liikkeelle koulukaupungeista, mutta levisi jo varhain myös ruotsinkieliselle maaseudulle. Vielä 1800-luvulla Hoosianna liittyi myös muihin kirkollisiin juhlatilaisuuksiin, kuten uusien kirkkojen vihkiäisiin. Säätyläiskodeissa sitä esitettiin myös piano- tai huilukappaleena. Suomenkielisille alueille ja Inkerinmaalle Hoosianna alkoi levitä 1870-luvulla. Kansakoulujen yleistyessä se saavutti myös paikan koulujen adventin- ja joulunvietossa. Hoosiannaa alettiin julkaista 1800-luvun jälkipuoliskolla monissa kuorokokoelmissa, moniäänisissä koululaulukirjoissa sekä messusävelmistöjen ja koraalikirjojen lopussa. Vähitellen se yleistyi myös yhteislauluun tarkoitetuissa laulukirjoissa, mutta löysi tiensä virsikirjaan vasta vuonna 1986. Hoosiannan suosiota selittää paljolti sen tarttuva melodia, joka poikkesi voimakkaasti oman aikansa muun jumalanpalvelusmusiikin tyylistä ja ihanteista. Tämän melodian pohjalta muokattiin 1800-luvun aikana myös ainakin kolme ehtoollisjumalanpalveluksen Pyhä-hymnin sävelmää, joista Fredrik August Ehrströmin tekemä oli käytössä vuoteen 2000 asti.
Georg Joseph Vogler’s Hosanna from late-eighteenth-century Stockholm is the reason why the First Advent Sunday is one of the most popular Sundays in Finland. Hosanna, originally a choral song for Palm Sunday, became established in nineteenth-century Sweden, Finland, and Ingria as part of the celebration of Advent. At first, it was performed by schoolchildren, but gradually choirs began to be assembled to sing it. The tradition started in the school towns and spread to the countryside. Hosanna was also performed in other celebrations, such as the inaugurations of new churches, and as an instrumental piece. It gained an irreplaceable place in the Advent and Christmas celebrations of primary schools. Hosanna began to be published in many choral collections, school songbooks, collections of liturgical melodies, and chorale books. Gradually, it also became common in songbooks intended for community singing but did not find its way into the Hymnal until in 1986. Hosanna’s popularity is predominantly explained by its catchy melody, which strongly differed from the style and ideals of liturgical music of its own time. Based on this melody, during the nineteenth century, at least three melodies of the Sanctus for the Communion Service were formed.

The Global 2:1 Mean-motion Resonance in HD 110067 is Not Vacant!
Authors: Christodoulou Dimitris M. , Laycock Silas G. T. , Kazanas Demosthenes
Published: December 2023

Extensive modeling of observations obtained by two space telescopes and 14 ground-based observatories revealed the presence of at least six closely packed planets orbiting HD 110067. Their orbital periods form a nearly perfect resonant chain, in which adjacent periods are in a geometric sequence with a ratio of r = 3/2 (planets b to e) that switches to r = 4/3 (planets e to g). The latter part of the sequence is based on single transits of planets f and g and their periods are model-dependent, as only first-order mean-motion resonances (MMRs) were so far investigated; and there is no physical justification for this assumption besides the simplicity imprinted on to the resonant chain itself. Furthermore, the global 2:1 MMR is apparently occupied, whereas this orbit is vacant in all other multibody (extra) solar systems. We summarize the physical arguments for/against the above r = 4/3 period ratios in anticipation of future observations to resolve the issue.

Published: December 2023

Anthomyiidae is a cosmopolitan and diverse family of Calyptratae, and is routinely considered to play key roles in both ecology and agriculture. The higher-level phylogenetic classification of Anthomyiidae has been highly controversial, necessitating further molecular data for precise reconstruction of phylogenetic relationships. In this study, we successfully acquired and annotated 18 new mitogenomes of anthomyiids. Moreover, the mitogenomes of the following genera Eustalomyia, Hyporites, Leucophora, Emmesomyia and Eutrichota are reported for the first time. The 18 mitogenomes are compared with confamilial species to assess genetic variation and to better understand evolutionary relationships within the family Anthomyiidae. In comparisons among 13 mitochondrial protein coding genes (PCG), the calculation of evolutionary rate exhibited nad1 as the fastest evolving gene in Anthomyiidae. Among the anthomyiids investigated, cox2 and nad4 had the lowest genetic distance across the 13 PCGs, suggesting a high degree of conservation for these two genes. Herein, we conducted phylogenetic analyses of the newly sequenced mitogenomes along with 11 known anthomyiids to investigate the interrelationships of Anthomyiidae. Our results indicate that Anthomyiidae is a monophyletic lineage and sister group to Scathophagidae, confirming prior findings based on morphological and molecular analyses. We recovered two subfamilies as monophyletic (Myopininae, Pegomyinae) while Anthomyiinae was polyphyletic. The great species diversity of anthomyiid flies limits the availability of mitogenomes for accurately resolving the phylogeny of Anthomyiidae. Nonetheless, our study provides novel insight into the molecular taxonomy, evolution, and phylogeny of the family Anthomyiidae.
Cortaderia selloana, an example of aggressive invaders that affect human health, yet to be included in binding international invasive catalogues
Authors: Liendo Diego , Campos Juan Antonio , Gandarillas Alberto
Published: December 2023

Invasive plant species can suppress local biodiversity, affect soil properties and modify the landscape. However, an additional concern of plant invasions that has been more disregarded is their impact on environmental human health. Here, we discuss the case of Cortaderia selloana (Schult. & Schult.f.) Asch. & Graebn, as an example of a worldwide invasive species with a strong environmental impact. We summarise the main facts regarding the C. selloana invasion, the recent clinical evidence of its impact on human health and the great potential expansion of the species in the context of climate change. C. selloana constitutes a clear example to boost demands from policy makers for urgent and efficient measures to control or eradicate invasive species, also in ruderal areas. This aggressive invader is still out of relevant binding international invasive species catalogues, including the European List of Invasive Alien Species of Union concern (Union list), and is still subjected to extensive trading in some European countries. Therefore, including C. selloana in the Union list becomes mandatory to impose full restrictions on keeping, importing, selling, breeding and cultivating the species.

How Nursing Should Respond to the Third Report of the Pew Health Professions
Authors: Fagin Claire
Published: December 2023

The Third Report of the Pew Health Professions Commission, "Critical Challenges: Revitalizing the Health Professions for the Twenty-First Century" (1995), describes a transformed U.S. health care industry characterized by systems of integrated care combining primary, specialty, and hospital services. Forecasting the success of such systems, the Report states that they will produce better management, accountability, responsiveness, more effective use of resources, innovation, and diversity in health delivery, inclusivity in the definition of health, more concern about education, prevention and care management rather than treatment, more orientation to what is improving the health of the entire population, and more reliance on outcomes data and evidence. The Report predicts that these changes will cause closure of as many as half of the nation's hospitals, expansion of primary care, surpluses in the supply of physicians, nurses, and pharmacists, consolidation of allied health professions, and demand for public health professionals. The Commission's seven recommendations for nursing deal with maximizing opportunities presented by the profession's educational diversity, regulation, and educational change, downsizing particularly in diploma and associate degree programs, expanding Master's level practitioner programs, developing new models of integration between education and the systems of health care, and "recovering" the clinical management role of nursing. This paper examines and critiques the recommendations of the Commission regarding nursing and discusses the challenges they present.

Published: December 2023

The aim of the current study is to reduce marijuana use among the general population. Because marijuana is an illegal narcotic with numerous negative health effects, it continues to pose a severe threat to public health in emerging nations. In this article, a modified mathematical model of the non-users, experimental users, recreational users, and addict's (NERA) model for marijuana consumption is established by incorporating a new compartment that represents the individuals who are being moved to jail by police intervention. The overall population of humans is divided into five main components: the non-smoker's compartment, experimental smoker's compartment, recreational smoker's compartment, addicted smoker's compartment, and prisoner's compartment. The novelty of this work is to modify the NERA model for marijuana consumption and validate the modified model. Furthermore, with the help of sensitivity analysis, control strategies for marijuana consumption in the population are addressed. The invariant region and the basic reproductive number (R0) are those parts that are needed for the validation of the proposed model. For the numerical simulation of the given model, the 4th-order Runge Kutta method will be used with the help of MATLAB to examine how the control strategies will play a role in marijuana consumption.
Deep learning-based sign language recognition system using both manual and non-manual components fusion
Authors: Jebali Maher , Dakhli Abdesselem , Bakari Wided
Published: December 2023

Sign language is regularly adopted by speech-impaired or deaf individuals to convey information; however, it necessitates substantial exertion to acquire either complete knowledge or skill. Sign language recognition (SLR) has the intention to close the gap between the users and the non-users of sign language by identifying signs from video speeches. This is a fundamental but arduous task as sign language is carried out with complex and often fast hand gestures and motions, facial expressions and impressionable body postures. Nevertheless, non-manual features are currently being examined since numerous signs have identical manual components but vary in non-manual components. To this end, we suggest a novel manual and non-manual SLR system (MNM-SLR) using a convolutional neural network (CNN) to get the benefits of multi-cue information towards a significant recognition rate. Specifically, we suggest a model for a deep convolutional, long short-term memory network that simultaneously exploits the non-manual features, which is summarized by utilizing the head pose, as well as a model of the embedded dynamics of manual features. Contrary to other frequent works that focused on depth cameras, multiple camera visuals and electrical gloves, we employed the use of RGB, which allows individuals to communicate with a deaf person through their personal devices. As a result, our framework achieves a high recognition rate with an accuracy of 90.12% on the SIGNUM dataset and 94.87% on RWTH-PHOENIX-Weather 2014 dataset.

The study first presents an overview of the IoMT before introducing the IoMT architecture. Later, it portrays an overview of the core technologies of the IoMT, including cloud computing, big data and artificial intelligence, and it elucidates their utilization within the healthcare system. Further, several emerging challenges, such as cost-effectiveness, security, privacy, accuracy and power consumption, are discussed, and potential solutions for these challenges are also suggested.
Generation of stochastic mixed-mode oscillations in a pair of VDP oscillators with direct-indirect coupling
Authors: Huang Xiaojun , Song Zigen
Published: December 2023

Environmental noise can lead to complex stochastic dynamical behavior in nonlinear systems. In this paper, we studied the phenomenon of a pair of Van der Pol (VDP) oscillators with direct-indirect coupling affected by Gaussian white noise. That is to say, a noise-induced equilibrium transition oscillation was observed in three types of different parameter regions, where the deterministic system had two kinds of stable equilibrium points. Meanwhile, with the noise intensity increasing, we found that the stochastic system will constantly switch between two stable equilibrium points. To analyze the stochastic behavior, we used the stochastic sensitivity equation and confidence ellipse method. When the confidence ellipsoid crossed the boundary of the attraction basin of the equilibrium point, the system entered into the state of stochastic mixed-mode oscillations, which was consistent with the simulation results.

Authors: Zhu Jiajun , Zhang Rui , Zhang Haifei
Published: December 2023

In order to improve the segmentation effect of brain tumor images and address the issue of feature information loss during convolutional neural network (CNN) training, we present an MRI brain tumor segmentation method that leverages an enhanced U-Net architecture. First, the ResNet50 network was used as the backbone network of the improved U-Net, the deeper CNN can improve the feature extraction effect. Next, the Residual Module was enhanced by incorporating the Convolutional Block Attention Module (CBAM). To increase characterization capabilities, focus on important features and suppress unnecessary features. Finally, the cross-entropy loss function and the Dice similarity coefficient are mixed to compose the loss function of the network. To solve the class unbalance problem of the data and enhance the tumor area segmentation outcome. The method's segmentation performance was evaluated using the test set. In this test set, the enhanced U-Net achieved an average Intersection over Union (IoU) of 86.64% and a Dice evaluation score of 87.47%. These values were 3.13% and 2.06% higher, respectively, compared to the original U-Net and R-Unet models. Consequently, the proposed enhanced U-Net in this study significantly improves the brain tumor segmentation efficacy, offering valuable technical support for MRI diagnosis and treatment.
Dynamics of a modified Leslie-Gower predator-prey model with double Allee effects
Authors: Xing Mengyun , He Mengxin , Li Zhong
Published: December 2023

In this paper, we investigate the dynamic behavior of a modified Leslie-Gower predator-prey model with the Allee effect on both prey and predator. It is shown that the model has at most two positive equilibria, where one is always a hyperbolic saddle and the other is a weak focus with multiplicity of at least three by concrete example. In addition, we analyze the bifurcations of the system, including saddle-node bifurcation, Hopf bifurcation and Bogdanov-Takens bifurcation. The results show that the model has a cusp of codimension three and undergoes a Bogdanov-Takens bifurcation of codimension two. The system undergoes a degenerate Hopf bifurcation and has two limit cycles (the inner one is stable and the outer one is unstable). These enrich the dynamics of the modified Leslie-Gower predator-prey model with the double Allee effects.

Published: December 2023

Superalloys, referred to as nickel alloys, have several uses in engineering and are widely used in industries that are as diverse as chemical processing and food processing. The high thermal conductivity and high strength of these materials make them hard to remove material from with traditional processing techniques. The majority of modern techniques for machining harder materials are alternatives to older methods. The present study is focusing on Wire Electrical Discharge Machining (WEDM), a modern machining technique used for the processing of tougher materials. The aspiration of this work is to present a Taguchi-based Grey technique that can be used to optimize a number of different performance indicators. The connection between the input and output variables has been analyzed using a regression model. Taguchi's design approach has been applied to the design of trials, with the Pulse on/off time and the applied current serving as independent variables. For enhancing the multiple machining performance of nickel alloy during Wire Electrical Discharge Machining (WEDM), this experimental effort seeks to pinpoint the most effective variables. This is accomplished using the Taguchi-Grey method. The performance analysis offers producers with concrete proof of the efficiency of evolved systems, allowing them to make well-informed and effective choices.

Various carbon-based (i.e., carbon nanofibres (CNF), cellulose nanocrystals and graphite nanoparticles) and silicon-based nanomaterials (i.e., silica and MMT clay nanoparticles) were incorporated into neat structural epoxy adhesive (NE) (Sikadur®-30) at 0.5, 1.0 and 1.5 wt.% by means of a simple and cost-effective mixing method to produce the nanomaterial-modified epoxy adhesives (NMEAs). The performance of the NMEAs in regard with the bond characteristics and strength of cement paste (CP)-adhesive joints was investigated through conducting lap-shear test. Results showed that loading epoxy with 0.5 and 1.0 wt.% of carbon-based nanofillers, except in the case of adding 1.0 wt.% CNF, contributed to a significant enhancement in the joints’ strength, but a strength reduction the of the joints, even below those of the NE-bonded joints, was observed upon a further loading (i.e., at 1.5 wt.%). While all the joints bonded with epoxy loaded with silicon-based nanofillers at all wt.% showed a strength increase over the unfilled epoxy. The joints’ strength was found to decrease with the wt.% of the nanofillers due to particles’ agglomerations. All joints failed in a mixed cohesive and adhesive mode.

Effective cooling of the electronic devices is of great importance to their performance. Of particular interest is when the size of the equipment has scaled down to micro level. Despite a continuous improvement over the years, there is only a handful information on gas-liquid flow in wavy microchannels. This paper presents an experimental study of the air-water two-phase flow in a wavy microchannels heatsink typically used for cooling of electronic devices. The heatsink was made from copper with 26 wavy channels. The width and the depth of each channel were 800 and 500 μm, respectively. Two cartridge heaters were used to generate a constant heat flux. Pressure and temperatures of the working fluid at the inlet and outlet of the test section were measured using a pressure transducer and thermocouples. To evaluate the benefit of using the wavy microchannels, experiment was performed using water as the working fluid. The results showed that the wavy microchannels could elevate the Nusselt number by up to 112% compared to that obtained from the straight microchannels. Experiments at various air and water flowrates in the wavy microchannels suggested that the advantages of using the air-water flow would be obvious at the liquid Reynolds number above 379.

The investigation of biomass-based, cost-effective, efficient, and environmentally materials with high power density and fast ion/electron transfer is intensively carried out for the development of renewable energy storage devices. Pyrolysis and hydrothermal carbonization (HTC) are two common methods of thermochemical conversion to synthesize biomass-derived based carbon. Compared to the pyrolysis method, HTC is a more promising strategy because it can be carried out without a pre-drying process, has a high yield, low ash content, and requires a relatively low temperature (180-250 °C). The carbon produced from the HTC process is known as hydrochar. This study reports the acid-assisted hydrothermal carbonization temperature on the hydrochar properties and its application for supercapacitor electrodes. Hydrochar was synthesized from extracted avocado seed waste with potassium permanganate and sulfuric acid catalyst solution at 200 °C for 12 h. The effect of one- and two-stage HTC temperature on the hydrochar properties were compared. The hydrochar characterization includes yield, SEM, XRD, FTIR, and cyclic voltammetry analysis. According to the characterization and analysis results, hydrochar produced has the 3D porous network morphology and the highest specific capacitance of 73.54 F/g. In conclusion, hydrochar derived from avocado seed through the acid-assisted HTC can be a potential way for supercapacitor electrodes.

The evaluation of metal oxides nanoparticles stability in the base fluids has become a major aspect in enhanced oil recovery process in recent years. Physical and chemical properties of ZnO nanofluids have caught attention of many researchers because they are easily dispersed in the base fluids, better convective coefficient of heat transfer, and wider bandgap which make them remarkable nanofluids candidate compared to other metal oxides. In this study, the stability of nanofluid of zinc oxide nanoparticles was evaluated using different stability tests and analysis. However, ZnO nanoparticles were synthesized using sol-gel method and nanofluids of different concentrations were prepared. The prepared nanoparticles were characterized using various characterization techniques such as XRD, FTIR, TEM, and Zeta sizer. The stability of prepared nanofluids was investigated using sedimentation test, UV-vis spectrophotometer, and zeta analyzer. Based on physical investigation and UV-vis spectra observations, ZnO nanoparticles in base fluids have shown a good colloidal stability in addition to their high zeta potential values of-43.7 (mV) after seven days which makes it a successful potential candidate for enhanced oil recovery applications.

Macrophages represent the most abundant immune component of the tumor microenvironment and often exhibit protumorigenic (M2-like) phenotypes that contribute to disease progression. Despite their generally accepted protumorigenic role, macrophages can also display tumoricidal (or M1-like) behavior, revealing that macrophages can be functionally reprogrammed, depending on the cues received within the tumor microenvironment. Moreover, such plasticity may be achieved by pharmacologic or biologic interventions. To that end, we previously demonstrated that a novel immunomodulator termed the “very small size particle” (VSSP) facilitates maturation of dendritic cells and differentiation of myeloid-derived suppressor cells to APCs with reduced suppressive activity in cancer models. VSSP was further shown to act in the bone marrow to drive the differentiation of progenitors toward monocytes, macrophages, and dendritic cells during emergency myelopoiesis. However, the underlying mechanisms for VSSP-driven alterations in myeloid differentiation and function remained unclear. In this study, in mouse models, we focused on macrophages and tested the hypothesis that VSSP drives macrophages toward M1-like functional states via IRF8- and PU.1-dependent mechanisms. We further hypothesized that such VSSP-mediated actions would be accompanied by enhanced antitumor responses. Overall, we showed that (1) VSSP drives naive or M2-derived macrophages to M1-like states, (2) the M1-like state induced by VSSP occurs via IRF8- and PU.1-dependent mechanisms, and (3) single-agent VSSP induces an antitumor response that is accompanied by alterations in the intratumoral myeloid compartment. These results provide a deeper mechanistic underpinning of VSSP and strengthen its use to drive M1-like responses in host defense, including cancer.
CHTOP Promotes Microglia-Mediated Inflammation by Regulating Cell Metabolism and Inflammatory Gene Expression

Published: December 2023

During the initiation of the inflammatory response of microglia, the expression of many inflammation- and cell metabolism–related genes alters. However, how the transcription of inflammation- and metabolism-related genes are coordinately regulated during inflammation initiation is poorly understood. In this study, we found that LPS stimulation induced the expression of the chromatin target of PRMT1 (protein arginine methyltransferase 1) (CHTOP) in microglia. Knocking down CHTOP in microglia decreased proinflammatory cytokine expression. In addition, CHTOP knockdown altered cell metabolism, as both the upregulated genes were enriched in cell metabolism–related pathways and the metabolites profile was greatly altered based on untargeted metabolomics analysis. Mechanistically, CHTOP could directly bind the regulatory elements of inflammation and cell metabolism–related genes to regulate their transcription. In addition, knocking down CHTOP increased neuronal viability in vitro and alleviated microglia-mediated neuroinflammation in a systemic LPS treatment mouse model. Collectively, these data revealed CHTOP as a novel regulator to promote microglia-mediated neuroinflammation by coordinately regulating the transcription of inflammation and cell metabolism–related genes.

Published: December 2023

Objective

Exercise-associated dehydration is a common problem, especially at sporting events. Although recommendations have been made to drink a certain volume per kilogram body mass lost after exercise, no clear guidance about the type of rehydration beverage is available. We conducted a systematic review to assess the effectiveness of carbohydrate-electrolyte (CE) solutions as a rehydration solution for exercise-associated dehydration.

Data Sources

MEDLINE (via the PubMed interface), Embase, and the Cochrane Library databases were searched up until June 1, 2022.

Study Selection

Controlled trials involving adults and children were included when dehydration was the result of physical exercise and when drinking carbohydrate-electrolyte solutions, of any percentage carbohydrate, was compared with drinking water. All languages were included if an English abstract was available.

Data Extraction

Data on study design, study population, interventions, outcome measures, and study limitations were extracted from each included article. Certainty was assessed using Grading of Recommendations Assessment, Development and Evaluation.

Data Synthesis

Of 3485 articles screened, 19 articles in which authors assessed CE solutions (0%–9% carbohydrate) compared with water were included. Although variability was present among the identified studies, drinking 0% to 3.9% and especially 4% to 9% CE solution may be effective for rehydration.

Conclusions

A potential beneficial effect of drinking CE drinks compared with water was observed for many of the reviewed outcomes. Commercial CE drinks (ideally 4%–9% CE drinks or alternatively 0%–3.9% CE drinks) could be suggested for rehydration in individuals with exercise-associated dehydration when whole foods are not available.
