Methodology: It was a retrospective, descriptive and comparative study carried out over five years (2018-2022) focusing on abdominal wall hernias in adults. Information was gathered from the patients’clinical notes and registers on the frequency of hernias, the anatomo-clinical forms of hernias, the type of anesthesia, the hernia repair technique and the postoperative evolution. Results: Of the 1022 and 1026 operations performed, 312 and 412 were hernial repairs, representing 30.5% and 41.2% of operations at RHC-T and PHC-K respectively (p = 0.001). The inguinal hernia was the most often found in 83.7% (n = 261) at RHC-T versus 76.6% (n = 324) at PHC-K. Herniorrhaphy was the most frequently used repair method, in 93.6% (n = 292) of patients at RHC-T and in 91.3% (n = 376) at PHC-K (p = 0.11). Postoperative complications were noted in 5.1% of cases (n = 16) at RHC-T versus 3.5% of cases (n = 15) at PHC-K (p = 0.307). These complications included scrotal hematomas, surgical areas infections, and orchitis. We recorded 1.3% (n = 4) and 0.8% (n = 3) deaths at RHC-T and PHC-K respectively (p = 0.496). Conclusion: There is homogeneity in the treatment of hernia in these two hospitals in Togo.展开更多

Rhesus macaques(Macaca mulatta, MMU)and crab-eating macaques(M. fascicularis, MFA) serve as crucial nonhuman primate biomedical models with different phenotypes. To date, however, large-scale comparative transcriptome research between these two species has not yet been fully explored. Here, we conducted systematic comparisons utilizing newly sequenced RNA-seq data from84 samples(41 MFA samples and 43 MMU samples)encompassing 14 common tissues. Our findings revealed a small fraction of genes(3.7%) with differential expression between the two species, as well as 36.5% of genes with tissue-specific expression in both macaques. Comparison of gene expression between macaques and humans indicated that 22.6% of orthologous genes displayed differential expression in at least two tissues. Moreover,19.41% of genes that overlapped with macaque-specific structural variants showed differential expression between humans and macaques. Of these, the FAM220A gene exhibited elevated expression in humans compared to macaques due to lineage-specific duplication. In summary,this study presents a large-scale transcriptomic comparison between MMU and MFA and between macaques and humans. The discovery of gene expression variations not only enhances the biomedical utility of macaque models but also contributes to the wider field of primate genomics.展开更多

Among the patients with active CD, 16 had anxiety. Compared withhealthy individuals, patients with active CD demonstrated significantly lower radial kurtosis values in the rightcerebellar region 6, lower axial kurtosis (AK) values in the right insula, left superior temporal gyrus, and rightthalamus, and higher slow and fast apparent diffusion coefficients (ADCslow and ADCfast) in the bilateral frontal lobe,bilateral temporal lobe, and bilateral insular lobe (all P < 0.05). Compared with patients with CD without anxiety,patients with CD and anxiety exhibited significantly higher ADCslow values in the left insular lobe and lower AKvalues in the right insula and right anterior cuneus (all P < 0.05).CONCLUSIONThere are variations in brain microstructure and perfusion among CD patients with/without anxiety and healthyindividuals, suggesting potential use in assessing anxiety-related changes in active CD.
文摘This paper conducted a more comprehensive review and comparative analysis of the two heavy to blizzard processes that occurred in the Beijing area during December 13-15,2023,and February 20-21,2024,in terms of comprehensive weather situation diagnosis,forecasting,and decision-making services,and summarized the meteorological service support experience of such heavy snow weather processes.It was found that both blizzard processes were jointly influenced by the 700 hPa southwesterly warm and humid jet stream and the near-surface easterly backflow;the numerical forecast was relatively accurate in the overall description of the snowfall process,and the forecast bias of the position of the 700 hPa southwesterly warm and humid jet stream determined the bias of the snowfall magnitude forecast at a certain point;when a deviation was found between the actual snowfall and the forecast,the cause should be analyzed in a timely manner,and the warning and forecast conclusions should be updated.With the full cooperation of relevant departments,it can greatly make up for the deviation of the early forecast snowfall amount,and ensure the safety and efficiency of people's travel.
文摘Objective: We aim to analyze the surgical nursery of abdominal wall hernias in adults between two poorly fitted medical environments, the Regional Hospital Center of Tsévié (RHC-T) and the Prefectural Hospital Center of Kpalimé (PHC-K) in Togo. Methodology: It was a retrospective, descriptive and comparative study carried out over five years (2018-2022) focusing on abdominal wall hernias in adults. Information was gathered from the patients’clinical notes and registers on the frequency of hernias, the anatomo-clinical forms of hernias, the type of anesthesia, the hernia repair technique and the postoperative evolution. Results: Of the 1022 and 1026 operations performed, 312 and 412 were hernial repairs, representing 30.5% and 41.2% of operations at RHC-T and PHC-K respectively (p = 0.001). The inguinal hernia was the most often found in 83.7% (n = 261) at RHC-T versus 76.6% (n = 324) at PHC-K. Herniorrhaphy was the most frequently used repair method, in 93.6% (n = 292) of patients at RHC-T and in 91.3% (n = 376) at PHC-K (p = 0.11). Postoperative complications were noted in 5.1% of cases (n = 16) at RHC-T versus 3.5% of cases (n = 15) at PHC-K (p = 0.307). These complications included scrotal hematomas, surgical areas infections, and orchitis. We recorded 1.3% (n = 4) and 0.8% (n = 3) deaths at RHC-T and PHC-K respectively (p = 0.496). Conclusion: There is homogeneity in the treatment of hernia in these two hospitals in Togo.
文摘This paper conducts clustering,potential semantic indexing,comparison,and inductive analysis of research papers on marketing between China and the UK from January 2020 to September 2024.The study found that the Chinese marketing research focuses on digital transformation,policy impact,value co-creation,and emerging e-commerce models.In contrast,the UK marketing research focuses more on sustainability,technology integration,real-time research,and personalized marketing strategies.The study also found that there were few marketing articles published in Chinese and CSSCI journals in China,while the SSCI journals published in English were 62 times more than in Chinese.According to the research,digital marketing and data-driven decision-making,diversified marketing channels,sustainability and circular economy,technological innovation and cutting-edge technology application,meta-universe and blockchain technology,AI+marketing development,brand building,and international market expansion will become the research hotspots in the field of marketing in the future.The research suggests that China should strengthen the construction of an academic marketing platform,and China and the UK should strengthen cooperation in marketing research,learn from each other's strengths,and jointly give full play to their advantages in technology application,market and economy,strategy and innovation,and social media,to contribute to global economic development and marketing research.
文摘The Russia-Ukraine conflict remains unresolved,while the armed conflict between Israel and Palestine continues to escalate,causing significant civilian casualties.To better protect the victims of war in armed conflicts,clarifying the applicability of international human rights law(IHRL)and international humanitarian law(IHL)in such contexts has become an urgent issue.A comparative study on the application of IHRL and IHL needs to address three key questions step by step:First,whether IHRL is applicable during armed conflicts;second,if applicable,how IHRL complements and interacts with IHL;and third,what methods should be adopted to resolve conflicts when IHRL and IHL are applied concurrently.In this context,an analysis of the historical development of IHRL and IHL reveals that the two share a common philosophical foundation,and thus they can be applied concurrently during armed conflicts.From an empirical perspective,IHRL engages with IHL through two approaches:interpreting IHL provisions and directly applying IHRL to armed conflicts,thereby fostering interactive development between the two.In cases where normative conflicts arise between IHRL and IHL,such as in the rules on the use of force and internment procedures,the principles of systemic integration and lex specialis can reconcile these conflicts during the application process.
文摘Rice and wheat provide nearly 40%of human calorie and protein requirements.They share a common ancestor and belong to the Poaceae(grass)family.Characterizing their genetic homology is crucial for developing new cultivars with enhanced traits.Several wheat genes and gene families have been characterized based on their rice orthologs.Rice–wheat orthology can identify genetic regions that regulate similar traits in both crops.Rice–wheat comparative genomics can identify candidate wheat genes in a genomic region identified by association or QTL mapping,deduce their putative functions and biochemical pathways,and develop molecular markers for marker-assisted breeding.A knowledge of gene homology facilitates the transfer between crops of genes or genomic regions associated with desirable traits by genetic engineering,gene editing,or wide crossing.

文摘Understanding gene expression variations between species is pivotal for deciphering the evolutionary diversity in phenotypes. Rhesus macaques(Macaca mulatta, MMU)and crab-eating macaques(M. fascicularis, MFA) serve as crucial nonhuman primate biomedical models with different phenotypes. To date, however, large-scale comparative transcriptome research between these two species has not yet been fully explored. Here, we conducted systematic comparisons utilizing newly sequenced RNA-seq data from84 samples(41 MFA samples and 43 MMU samples)encompassing 14 common tissues. Our findings revealed a small fraction of genes(3.7%) with differential expression between the two species, as well as 36.5% of genes with tissue-specific expression in both macaques. Comparison of gene expression between macaques and humans indicated that 22.6% of orthologous genes displayed differential expression in at least two tissues. Moreover,19.41% of genes that overlapped with macaque-specific structural variants showed differential expression between humans and macaques. Of these, the FAM220A gene exhibited elevated expression in humans compared to macaques due to lineage-specific duplication. In summary,this study presents a large-scale transcriptomic comparison between MMU and MFA and between macaques and humans. The discovery of gene expression variations not only enhances the biomedical utility of macaque models but also contributes to the wider field of primate genomics.
