Authors:   Department of Pharmacology, All India Institute of Medical Sciences, Saket Nagar, Bhopal - 462020, Madhya Pradesh, India, Chenchula Santenna
Published: January 2023

Zaltoprofen, a unique propionic acid group of NSAIDs, works by blocking the enhancing effects of bradykinin along with the COX-2 enzyme. Therefore, it is of interest to evaluate the acute and chronic anti-inflammatory (arthritic) potential of zaltoprofen versus piroxicam in Murine models. A total of 48 Wister rats (200-250 g) of either sex (24 in each model) were used in the present study. The anti-inflammatory and arthritic potential of zaltoprofen was evaluated and compared by Carrageenan-induced acute inflammation and formalin-induced chronic inflammation. There was a significant inhibition of paw volume (P<0.001) on different time scales with two different doses of the test compound (Zaltoprofen 10 & 20 mg/kg) in the acute inflammation model compared to the negative control (NaCl 10 ml/kg). However, in the chronic inflammation model, zaltoprofen 10 mg/kg and 20 mg/kg doses of the test compound showed a significant reduction in chronic inflammation, comparable to the negative control (NaCl 10 ml/kg), although the potency was lower than the positive control (piroxicam 10 mg/kg) (P 0.05). Thus, zaltoprofen shows significant anti-inflammatory and arthritic effects in both acute and chronic models by inhibiting various inflammatory mediators.

Authors:   Rayat Bahra Dental College, Mohali, Punjab, India, Sood Ridhima
Published: January 2023

The present randomized control was conducted clinically to evaluate the effectiveness of Acellular Dermal Matrix Allograft (ADMA) and Subepithelial Connective Tissue Graft (SCTG) in combination with Coronally Positioned Flap (CPF) in the treatment of Miller's class I and II multiple gingival recession in aesthetic areas. A total of 20 patients aged between 18 to 40 years were selected for this study, meeting all the criteria for inclusion. 10 patients were treated with ADMA and 10 patients with SCTG in combination with CPF. Various clinical parameters were assessed viz. probing pocket depth (PPD), clinical attachment level (CAL), gingival recession height (RH) and width of keratinized gingiva (WKG) at baseline and 6 months after surgery. The mean RH at baseline in the control and test groups was 3.05 ±0 .55(mean± SD) and 2.60 ±.99 respectively. At 3 months the mean RH was found to be 1.60±0.74 and 1.05 ± .60 in the control and test group respectively. The mean percentage of root coverage (MRC%) at 6 months in the control and test group was 65.69 ±26.52 (mean± SD) and 65.54 ±.9.16 respectively but no statistically significant difference was seen between the two groups. The results of the study suggest that the combination of both subepithelial connective tissue graft and acellular dermal matrix graft with a coronally positioned flap can produce an equivalent amount of esthetic root coverage.

Published: January 2023

t is of interest to synthesize Nano eggshell-titanium-dioxide (EB@TiO2) biocomposite and to evaluate its effectiveness in occluding opened dentine tubules. EB@TiO2 was synthesized and characterized using X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). Sixteen simulated bovine dentine discs were prepared and randomly assigned into four groups according to the following treatment (n = 4): Group 1: No treatment; Group 2: eggshell powder; Group 3: EB@TiO2; and Group 4: GIC mousse. These were then, agitated in a solution of 1g powder and 40mL water for 3hours. Thereafter, each dentine discs from the respective groups were post-treated for 5 min with 2wt% citric acid to test their acid resistant characteristics. Scanning Electron Microscope (SEM) was used to observe the effectiveness of occluded dentine pre-treatment and post-treatment. The cytotoxicity of the synthesized EB@TiO2 was tested using NIH 3T3 assay. ANOVA was used to evaluate the mean values of the occluded area ratio and the data of MTS assay. This was followed by a multi-comparison test with Bonferroni correction (α = .05). The XRD confirmed that EB@TiO2 was successfully modified through ball-milling. The TEM revealed the presence of both spherical and irregular particle shape powders. The SEM result showed that EB@TiO2 could effectively occlude open dentine tubules. Equally, the result demonstrated that EB@TiO2 exhibited the highest acid resistant stability post-treatment. NIH 3T3 assay identified that EB@TiO2 had little effect on the NIH 3T3 cell line even at the highest concentration of 100μg/ml. This study suggests that the application of EB@TiO2 effectively occluded dentine tubules and the occlusion showed a high acid resistant stability.

Authors:   Department of Obstetrics and Gynaecology, Andaman and Nicobar Islands Institute of Medical Sciences, Port Blair - 744104, Andaman and Nicobar Islands, India, Patil Sudha
Published: January 2023

Polycystic Ovary Syndrome (PCOS) is a hormonal condition where women reproductive hormones are out of endocrinal balance. Women with PCOS frequently exhibit obesity, which causes irregularities in the levels of adipocytes like adiponectin. It is hypothesized that the altered adiponectin levels also play a role in the endocrine and metabolic abnormalities seen in PCOS women. We aimed to study the association of adiponectin levels with PCOS women. This case control study included 60 PCOS women under 30 age, and BMI matched healthy controls were recruited. For all the subjects Biochemical and serum adiponectin were determined. The serum adiponectin shows significantly decreased in PCOS women when compared to healthy controls (P <0.001**). This levels were inversely associated with BMI and total cholesterol, triglycerides in women with PCOS (P<0.001**). The significantly decreased levels of serum adiponectin can be useful for diagnostic and prognostic tool for PCOS in women and its application can be used for the success of specific emerging treatment modalities where the follow up shows improvement of levels of adiponectin.

Diabetic kidney disease is a common cause of end stage renal disease has a high incidence rate in population with type 2 diabetes mellitus patients. Adiponectin is an adipocytokine shown to strive anti-diabetic, anti-oxidative as well as anti-inflammatory. The present study aimed to determine the serum adiponectin levels in type 2 diabetes mellitus and explore its association with nephropathy. This cross sectional study recruited 90 type 2 diabetes mellitus patients with (n = 60) and without nephropathy (n = 30). Additionally 30 age-, gender, and body mass index matched healthy controls were included. Enzyme linked immunosorbent assay method were used to determine adiponectin concentration. Blood sugars, glycated hemoglobin, body mass index all sounded to be brawny risk factors for nephropathy and microalbumin, e GFR showed a significant association with kidney disease progression in type 2 diabetes mellitus with nephropathy. Both the groups of type 2 diabetes mellitus patients had elevated adiponectin concentrations than controls. Serum adiponectin concentrations were significantly higher in type 2 diabetes mellitus without nephropathy and there was a significant association with nephropathy activity (P<0.0001**). The receiver operating characteristics curve analysis was used to examine the diagnostic performance of adiponectin for nephropathy shown a significant area under the curve 0.998 with sensitivity 100% and specificity 93.33% (P<0.0001**). Hence our study findings concluded that serum adiponectin concentrations considered for the early predictable and prognostic marker for nephropathy.

Published: January 2023

Globally, there is increased customer mobility and competition within the higher education sector. As such, university management and administration practices should consider academic satisfaction, quality and loyalty as important factors to influence graduate job performance. The study was conducted to see if self-perceived job performance had a role in mediating the effect of academic satisfaction and perceived academic quality on academic loyalty. Data was collected from 714 respondents using a cross-sectional survey. The covariance-based structural equation modelling was used to test the hypotheses. According to the study results, self-perceived job performance partially mediates the effect of both academic satisfaction and academic quality on academic loyalty. The study findings emphasise the importance of graduate quality and satisfaction in influencing loyalty. Thus, the higher education sector should take cognisance of self-perceived job performance as this also influences academic loyalty.

La pesca en la ciudad romana de Tróia (Carvalhal, Portugal): reconstrucción de los aparejos de caña y sedal a partir de los anzuelos
Authors: Vargas Girón José Manuel , Magalhães Ana Patricia
Published: January 2023

Tróia (Carvalhal, Portugal) constituye uno de los grandes centros pesquero-conserveros del mundo romano, tal y como ponen de manifiesto los restos arquitectónicos actualmente conservados en el yacimiento, pertenecientes mayoritariamente a cetariae. Otras evidencias que verifican la importancia de las actividades haliéuticas en Tróia son las artes de pesca, documentándose un gran número de instrumental pesquero que ha sido objeto de estudio recientemente en el Museo Nacional de Arqueología de Lisboa. Los materiales, procedentes de antiguas excavaciones y casi en su mayoría inéditos, se corresponden con anzuelos, pesas, agujas y lanzaderas. En este trabajo se dan a conocer los anzuelos de pesca (setenta y siete ejemplares), presentándose un análisis morfo-tipológico y métrico de los mismos, comparándose la muestra inventariada con otros conjuntos de anzuelos romanos estudiados en la Península Ibérica como es el caso de la ciudad hispanorromano de Baelo Claudia.
El Aziliense cantábrico y la continuidad cultural en la transición Pleistoceno superior/Holoceno
Authors: Álvarez Alonso David , Hevia Carrillo Aitor , De Andrés Herrero María , Usano Carbajo Matilde
Published: January 2023

El presente trabajo se centra en exponer un estado de la cuestión sobre el Aziliense cantábrico, haciendo hincapié en la caracterización tecnológica y en el marco cronológico y paleoambiental. A pesar de su consideración transicional entre el Pleistoceno final y el comienzo del Holoceno, el Aziliense es un fenómeno plenamente pleistoceno, que se desarrolla en los momentos finales del tardiglaciar (aunque su extensión final llegue al comienzo del Holoceno). Por otra parte, a pesar de las diferencias existentes entre el Magdaleniense y el Aziliense, este último no deja de ser la continuación del anterior y la última fase del Paleolítico superior, donde quedan en evidencia una serie de procesos de cambio, que claramente no tienen que ver en primera instancia con los cambios climáticas que suponen la llegada del Holoceno.

Social and legal conditionality of confiscation of property in domestic criminal legislation
Authors: Bargaev Damir Kamilevich
Published: January 2023

The object of the study is the reasons for the existence of confiscation of property in criminal legislation. The socio-legal conditionality of the named institute is designed to reveal the functional purpose of the criminal instrument, its social role and place in the system of combating crime. Special attention is paid to the method of analysis, with the help of which the necessary data are investigated to confirm the hypothesis of the social necessity of the existence of the institution of confiscation of property. The institution of criminal law confiscation of property is an effective tool of the state's anti-criminal policy, the content and purpose of which have been dynamically transformed throughout the history of Russian society. The basis of the research is a synthesis of domestic as well as foreign legislative and doctrinal provisions using the formal legal method. The main conclusions of the study are that the socio-legal conditionality of the criminal law institution of confiscation of property is expressed in compensation for the negative consequences of the crime committed by asymmetric compensation for damage to legally protected public relations. Confiscation of property acts as a means of criminal law repression, designed to impose on the convicted person the obligation to suffer the negative consequences of the crime committed by him. Through the institution of confiscation, the criminal legislator focuses on law-abiding behavior related to economic and financial activities. The novelty of the study is represented by a system of key factors (reasons) justifying the need for the existence of the institution of confiscation of property in domestic criminal legislation.
The Maastricht Treaty and the accession of the Western Balkans. Reflections at its 30th anniversary over the coherence in the EU integration processes.
Authors: Musaraj Arta
Published: January 2023

At its 30th anniversary, the Maastricht Treaty remains a milestone in the history and practice of the European Union. This referring to the adhesion process, since the set of conditions that a country must accomplish have been settled and derived by the treaty, but also for the fact that now, after 20 years of entering in force, the Euro, the Union currency, has performed and faced different consecutive challenges, thus becoming observable concerning it effects and role, and as a consequence, its theoretical and practical validity. But there is yet a vast area, in the center of Europe, that is still dragging on its calvary of adhesion, that of the Western Balkans. At this point, considering the processes that the countries of this area have been going through, by pursuing the adhesion path, the analysis of the dominating factors that have determined the trajectory of their EU membership, becomes essential. The paper questions and analyses the validity of the Maastricht Treaty and subsequent criteria for the adhesion of the Western Balkan countries, as well as highlights on the ‘ad-hoc’ criteria and evaluations often applied during the process and their consequences in terms of the attitudes of the Balkan populations and their determination toward the EU and the Western Balkans adhesion.
Temporal context and latent state inference in the hippocampal splitter signal
Authors: Duvelle Éléonore , Grieves Roddy M , van der Meer Matthijs AA
Published: January 2023

The hippocampus is thought to enable the encoding and retrieval of ongoing experience, the organization of that experience into structured representations like contexts, maps, and schemas, and the use of these structures to plan for the future. A central goal is to understand what the core computations supporting these functions are, and how these computations are realized in the collective action of single neurons. A potential access point into this issue is provided by ‘splitter cells’, hippocampal neurons that fire differentially on the overlapping segment of trajectories that differ in their past and/or future. However, the literature on splitter cells has been fragmented and confusing, owing to differences in terminology, behavioral tasks, and analysis methods across studies. In this review, we synthesize consistent findings from this literature, establish a common set of terms, and translate between single-cell and ensemble perspectives. Most importantly, we examine the combined findings through the lens of two major theoretical ideas about hippocampal function: representation of temporal context and latent state inference. We find that unique signature properties of each of these models are necessary to account for the data, but neither theory, by itself, explains all of its features. Specifically, the temporal gradedness of the splitter signal is strong support for temporal context, but is hard to explain using state models, while its flexibility and task-dependence is naturally accounted for using state inference, but poses a challenge otherwise. These theories suggest a number of avenues for future work, and we believe their application to splitter cells is a timely and informative domain for testing and refining theoretical ideas about hippocampal function.

The paper deals with Ukrainian President’s Zelensky image in political cartoons and memes. They are forms of political humour and can be examined in an interdisciplinary manner. The first part describes theoretical aspects, functions, and elements of political humour and political satire, main features and types of cartoons and memes. In the second part, the corpus of 198 political cartoons and 1121 memes from March 2019 to December 2020 is analysed with computer-aided content analysis and multimodal discourse analysis. The analysis units are social context, formed by the domestic and foreign political events in Ukraine in the research period, joke techniques and communication levels in the cartoons and memes. These units are examined chronologically and thematically. The research is based on the hypothesis about the interdependence of social context and subversive/supportive humour in the construction of Zelensky’s image.
Caricaturing the enemy

Published: January 2023

A century ago, the Greek-Turkish War of 1919-1922 (Turkish War of Liberation/Asia Minor Campaign) was reaching its culmination point. The war was also fought in the pages of the Press. In this study, we look at the characteristics of the caricatures marshalled in the war effort by three publications. The Greek newspaper Skrip, and the Turkish satirical magazines Karagöz and Güleryüz. We find that most expectations based on semiotics and the concept of interstate rivalry are borne out. Depictions of the ‘Other’ are generally negative. That said we also find that Skrip dedicated the majority of its caricatures to targeting the internal ‘Other’, the Venizelist faction during the National Schism, in contrast to the more focused targeting of the Greek ‘Other’ by the Turkish publications. This finding indicates the dominance of domestic conflicts over the external conflict even during the inflation point of the Greek-Turkish Interstate Rivalry of 1866-1925.
The complex role of transcription factor GAGA in germline death during Drosophila spermatogenesis: transcriptomic and bioinformatic analyses

Published: January 2023

The GAGA protein (also known as GAF) is a transcription factor encoded by the Trl gene in D. melanogaster. GAGA is involved in the regulation of transcription of many genes at all stages of fly development and life. Recently, we investigated the participation of GAGA in spermatogenesis and discovered that Trl mutants experience massive degradation of germline cells in the testes. Trl underexpression induces autophagic death of spermatocytes, thereby leading to reduced testis size. Here, we aimed to determine the role of the transcription factor GAGA in the regulation of ectopic germline cell death. We investigated how Trl underexpression affects gene expression in the testes. We identified 15,993 genes in three biological replicates of our RNA-seq analysis and compared transcript levels between hypomorphic TrlR85/Trl362 and Oregon testes. A total of 2,437 differentially expressed genes were found, including 1,686 upregulated and 751 downregulated genes. At the transcriptional level, we detected the development of cellular stress in the Trl-mutant testes: downregulation of the genes normally expressed in the testes (indicating slowed or abrogated spermatocyte differentiation) and increased expression of metabolic and proteolysis-related genes, including stress response long noncoding RNAs. Nonetheless, in the Flybase Gene Ontology lists of genes related to cell death, autophagy, or stress, there was no enrichment with GAGA-binding sites. Furthermore, we did not identify any specific GAGA-dependent cell death pathway that could regulate spermatocyte death. Thus, our data suggest that GAGA deficiency in male germline cells leads to an imbalance of metabolic processes, impaired mitochondrial function, and cell death due to cellular stress.
Substantial changes in Gaseous pollutants and health effects during COVID-19 in Delhi, India
Authors: Singh Bhupendra , Pandey Puneeta , Wabaidur Saikh Mohammad , Avtar Ram , Kumar Pramod , Rahman Shakilur
Published: January 2023

Background

Coronavirus disease has affected the entire population worldwide in terms of physical and environmental consequences. Therefore, the current study demonstrates the changes in the concentration of gaseous pollutants and their health effects during the COVID-19 pandemic in Delhi, the national capital city of India.

Methodology

In the present study, secondary data on gaseous pollutants such as nitrogen dioxide (NO2), carbon monoxide (CO), sulfur dioxide (SO2), ammonia (NH3), and ozone (O3) were collected from the Central Pollution Control Board (CPCB) on a daily basis. Data were collected from January 1, 2020, to September 30, 2020, to determine the relative changes (%) in gaseous pollutants for pre-lockdown, lockdown, and unlockdown stages of COVID-19.

Results

The current findings for gaseous pollutants reveal that concentration declined in the range of 51%–83% (NO), 40%–69% (NOx), 31%–60% (NO2), and 25%–40% (NH3) during the lockdown compared to pre-lockdown period, respectively. The drastic decrease in gaseous pollutants was observed due to restricted measures during lockdown periods. The level of ozone was observed to be higher during the lockdown periods as compared to the pre-lockdown period. These gaseous pollutants are linked between the health risk assessment and hazard identification for non-carcinogenic. However, in infants (0–1 yr), Health Quotient (HQ) for daily and annual groups was found to be higher than the rest of the exposed group (toddlers, children, and adults) in all the periods.

Conclusion

The air quality values for pre-lockdown were calculated to be “poor category to “very poor” category in all zones of Delhi, whereas, during the lockdown period, the air quality levels for all zones were calculated as “satisfactory,” except for Northeast Delhi, which displayed the “moderate” category. The computed HQ for daily chronic exposure for each pollutant across the child and adult groups was more than 1 (HQ > 1), which indicated a high probability to induce adverse health outcomes.
Construction of an anthropometric discriminant model for identification of elite swimmers: an adaptive lasso approach
Authors: Pan Qile , Zhu Rongxin , Qiu Jun , Cai Guang
Published: January 2023

Background

Anthropometric characteristics are important factors that affect swimming performance. The aim of this study is to build a discriminant model using anthropometric factors to identify elite short-to-medium-distance freestyle swimmers through an adaptive Lasso approach.

Methods

The study recruited 254 swimmers (145 males and 109 females) who were divided them into elite (aged 17.9 ± 2.2 years, FINA points 793.8 ± 73.8) and non-elite (aged 17.1 ± 1.3 years, FINA points 560.6 ± 78.7) groups. Data for 73 variables were obtained, including basic information, anthropometric and derivative indicators. After filtering out highly correlated variables, 24 candidate variables were retained to be used in adaptive Lasso to select variables for prediction of elite swimmers. Deviance and area under the curve (AUC) were applied to assess the goodness of fit and prediction accuracy of the model, respectively.

Results

The adaptive Lasso selected 12 variables using the whole sample, with an AUC being 0.926 (95% CI [0.895–0.956]; P = 2.42 × 10−29). In stratified analysis by gender, nine variables were selected for male swimmers with an AUC of 0.921 (95% CI [0.880–0.963]; P = 8.82 × 10−17), and eight variables were for female swimmers with an AUC of 0.941 (95% CI [0.898–0.984]; P = 7.67 × 10−15).

Conclusion

The adaptive Lasso showed satisfactory performance in selecting anthropometric characteristics to identify elite swimmers. Additional studies with longitudinal data or data from other ethnicities are needed to validate our findings.

Because of this, the present research work was carried out to assess the correlation coefficient and path analysis among thirty maize inbred lines for eighteen yield, yield contributing characters and seedling vigour traits in maize (Zea mays L.).

Results: Correlation studies revealed that plant height (0.3566**), ear height (0.2135**), ear length (0.3505**), ear diameter (0.4973**), number of kernel rows (0.3471**), 100-seed weight (0.5359**), cob yield per plant (0.9883**) and seed vigour index-2 (0.3412**) were significant and positively correlated with the grain yield per plant. Path analysis showed that cob yield per plant had the highest positive direct effect on grain yield per plant followed by shelling percentage (0.0094), seed vigour index -1 (0.0131), seed vigour index-2 (0.0125), 100 seed weight (0.0122), days to tasseling (0.0108), germination first count (0.0094), speed of germination (0.0060), number of kernels per row (0.0058), ear diameter (0.0057) suggesting that grain yield could be indirectly enhanced by the selection of these characters.

The experiment was laid down with fourteen treatments, viz.T1 (Control), T2 (100% RDN (through urea)) + 50% RDN through FYM), T3 (75% RDN + 25% N through FYM), T4 (50% RDN + 50% N through FYM), T5 (25% RDN + 75% N through FYM), T6 (100% N through FYM), T7 (75% RDN + 25% N through Vermicompost), T8 (50% RDN + 50% N through Vermicompost), T9 (25% RDN + 75% N through Vermicompost), T10 (100% N through Vermicompost), T11 (75% RDN + 25% N through Poultry manure), T12 (50% RDN + 50% N through Poultry manure), T13 (25% RDN + 75% N through Poultry manure) and T14 (100% N through Poultry manure). Different nitrogen sources affected the yield and yield attributes variably. Highest (56.90, 90.07, 95.42 cm) and lowest (46.63, 77.37, 84.02 cm) plant height was observed in treatments T2 and T1 at 30 DAT, 60 DAT and harvest stage, respectively. The number of tillers varied from 166.14 (T1) to 205.15 (T2), 213.00 (T1) to 372.17 (T2) and 205.90 (T1) to 364.47 (T2) m-2 among different treatments at 30 DAT, 60 DAT and harvest stage, respectively. Highest grain yield (44.61 q ha-1) was observed in T2 and lowest (28.55 q ha-1) in T1. Treatment T6 and T1 showed highest and lowest straw yield with 52.28 and 32.93 q ha-1, respectively. Higher biological yield (96.88 q ha-1) was recorded with treatment T2 while lowest was recorded with treatment T1 with 61.48 q ha-1. Highest (46.99%) and lowest (43.18%) harvest index was observed in T6 and T1, respectively. In the treatments where N was applied either through manures alone or in combination with chemical fertilizer (urea), highest growth parameters (plant population and Plant height), yield and yield attributes (number of tillers, test weight) was observed higher in poultry manure as compared to vermicompost and FYM.

Recently, board diversity has become an essential part of the modern business environment. Its awareness rises since it affects how the board carries out its duties, the board's efficacy, and the risk-taking behavior, leading to companies' outcomes and value. Therefore, the researchers conducted the study to know the impact of board diversity, precisely, the Board of Commissioner and corporate risk with the diversity of gender, age, nationality, education, and tenure. Board size, market to book ratio, tangibility, leverage, and profitability were used as control variables. This study focused on Indonesia's manufacturing companies listed in the IDX during 2016-2019, with 300 sample data collected from 75 companies. The data gathered were further analyzed using multiple linear regression. As a result, nationality diversity, tangibility, leverage, and profitability significantly affect corporate risk. Inversely, diversity of gender, age, education, tenure, the board size, and market-to-book ratio do not significantly affect corporate risk.

Authors: Harianto Agung
Published: January 2023

Penelitian ini bertujuan untuk membuktikan bahwa terdapat pengaruh positif tetapi tidak signifikan Information Sharing terhadap relationship commitment. Pengalaman buruk yang di alami hotel terhadap supplier bisa menyebabkan hasil penelitian tidak sejalan. faktor kepercayaan karakteristik didasarkan pada persepsi timbal balik, pengalaman masa lalu yang positif atau negatif. Dari pengalaman yang buruk tersebut membuat kepercayaan hotel terhadap supplier menurun. Hasil penelitian menunjukkan bahwa pengaruh kepercayaan terhadap relationship commitment pada hotel berbintang 3- 5 di Surabaya sesuai dengan apa yang ada  di lapangan yaitu dimana hotel memiliki kekuasaan untuk memilih supplier sehingga tidak terjadinya ketergantungan hotel dengan 1 supplier saja. Apabila hotel merasa supplier tidak kompeten maka hotel bisa membatalkan perjanjian secara sepihak maupun berhenti memesan barang pada supplier tersebut. Berdasarkan hasil penelitian diketahui bahwa information sharing penting bagi industri yang menggunakan supply chain yang tujuannya untuk mengambil keputusan hotel yang lebih baik dan berdasarkan information yang dapat dipercaya. Hotel sangat menghargai information sharing mengenai perubahan harga yang terjadi sehingga hotel akan mengevaluasi kembali mengenai pembelian dan persediaan hotel. Status pengiriman juga menjadi penilaian penting untuk hotel karena mereka juga tidak ingin barang mereka lama datangnya sehingga status pengiriman penting untuk diperhatikan.

Atherosclerosis accounts for major mortality of cardiac‐cerebral vascular diseases worldwide. Pathologically, persistent inflammation dominates the progression of atherosclerosis, which can be accelerated by a high‐fat diet (HFD), possibly through triggering local intestinal oxidative stress and ensuing gut barrier dysfunction. Current pharmacotherapy has been disappointing, ascribed to limited therapeutic efficacy and undesirable side effects. Hence it is compelling to explore novel efficient anti‐atherosclerotic drugs with minimal toxicity. Herein, two fullerene‐based therapies with exceptional antioxidant capacity, in the form of water‐soluble injectable fullerene nanoparticles (IFNPs) and oral fullerene tablets (OFTs), are demonstrated to retard HFD‐fueled atherosclerosis in ApoE−/‐ mice with favorable biosafety. Especially, OFTs afford robust anti‐atherosclerotic therapeutic even against advanced plaques, besides stabilizing plaques with less lipid deposition and improved collagen expression. Specifically, it is identified that OFTs can ameliorate HFD‐induced dysregulated intestinal redox homeostasis and restore gut barrier integrity, thereby restraining the translocation of luminal lipopolysaccharide (LPS) into the bloodstream. Furthermore, significantly reduced circulating LPS after OFTs treatment contributes to down‐regulated LPS/TLR4/NF‐κB signaling in aortic focal, which further mitigates local inflammation and disease development. Overall, this study confirms the universal anti‐atherosclerotic effect of fullerenes and provides a novel therapeutic mechanism via modulating intestinal barrier to attenuate atherosclerosis.
