ABSTRACT This study was conducted to investigate the polymorphism of the silence information regulator 5 (SIRT5) gene in 103 Congjiang Xiang pigs from Southwest China. We searched for SNP (single nucleotide polymorphism) loci of SIRT5 gene through sequence alignment and PCR. We obtained nine SNP loci: g.14135 A>C (intron 6), g.14247 C>A (intron 6), g.14305 C>T (exon 7), g.14335 C>T (exon 7), g.16603 T>C (intron 7), g.16613 T>C (intron 7), g.16800 G>A (intron 7), g.16812 C>G (intron 7), and g.16916 A>G (exon 8). Further analysis of SNP genotypes associated with the carcass traits of skin thickness, backfat thickness, and eye muscle area was carried out in pigs. We found that the genotypes g.14305 C>T (CC) and g.16812 C>G (CG) had certain advantages for improving the carcass traits of Congjiang Xiang pigs. The haplotype combination of the SIRT5 gene that improved skin thickness was H2H3:CCGGCTCA. These results may provide empirical support for molecular-based breeding of carcass traits in Congjiang Xiang pigs.

ABSTRACT Objective: To investigate the effect of improving the operative field and postoperative atelectasis of single-lung ventilation (SLV) in the surgical repair of coarctation of the aorta (CoA) in infants without the use of cardiopulmonary bypass (CPB). Methods: This was a retrospective cohort study. The clinical data of 28 infants (aged 1 to 4 months, weighing between 4.2 and 6 kg) who underwent surgical repair of CoA without CPB from January 2019 to May 2022 were analyzed. Fourteen infants received SLV with a bronchial blocker (Group S), and the other 14 infants received routine endotracheal intubation and bilateral lung ventilation (Group R). Results: In comparison to Group R, Group S exhibited improved exposure of the operative field, a lower postoperative atelectasis score (P<0.001), reduced prevalence of hypoxemia (P=0.01), and shorter durations of operation, mechanical ventilation, and ICU stay (P=0.01, P<0.001, P=0.03). There was no difference in preoperative information or perioperative respiratory and circulatory indicators before SLV, 10 minutes after SLV, and 10 minutes after the end of SLV between the two groups (P>0.05). Intraoperative bleeding, intraoperative positive end-expiratory pressure (PEEP), and systolic pressure gradient across the coarctation after operation were also not different between the two groups (P>0.05). Conclusion: This study demonstrates that employing SLV with a bronchial blocker is consistent with enhanced operative field, reduced operation duration, lower prevalence of intraoperative hypoxemia, and fewer postoperative complications during the surgical repair of CoA in infants without the use of CPB.

ABSTRACT Habitat loss and land use changes resulting from urbanization in residential communities are among the greatest threats to wild mammals. Identifying anthropogenic factors determining mammal diversity and composition can help coordinate socio-economic development with ecological conservation. In this study, we used transect surveys to compare the mammal assemblages near human-disturbed communities with those in the natural off-community area around Beijing, a major metropolis. We assessed the variables affecting the mammals’ presence using 19 environmental indicators. Of the twelve mammal species detected in the area, three vulnerable species have obtained legislative protection. In 58% of the observations, mammals were discovered around communities closer to croplands and located at slightly higher elevations with less vegetation, and these are the main environmental variables contributing to more mammals’ presences in the disturbed near-community area. The selection of croplands for the mammals in the suburb should be a trade-off between feeding benefits and predation risks, and with the rise of protection willingness, green zones near residential communities can serve as additional habitats for mammals facing the expansion of urbanization. socioeconomic socio economic conservation study humandisturbed human offcommunity off community Beijing metropolis 1 indicators 58 observations vegetation nearcommunity tradeoff trade risks willingness 5

RESUMO Para avaliar de forma rápida e precisa o crescimento de plantas de chá, este estudo visa encontrar uma nova maneira de prever o conteúdo de clorofila em dosséis de plantas de chá usando aprendizado de máquina. Utilizando aeronaves pilotadas remotamente equipadas com câmeras multiespectrais, imagens de áreas de plantações de chá são capturadas e a reflectância de quatro bandas espectrais é extraída, levando ao cálculo de índices de vegetação. Simultaneamente, o conteúdo relativo de clorofila nos dosséis das plantas de chá foi coletado no terreno usando um detector. Quatro modelos, nomeadamente Floresta Aleatória (RF), rede neural de retropropagação (BPNN), rede de função de base radial (RBFN) e Rede Neural de Regressão Geral (GRNN), foram construídos para prever o conteúdo relativo de clorofila nos dosséis das plantas de chá. Subsequentemente, variáveis importantes de sensoriamento remoto foram identificadas através de filtragem RF, seguidas por uma comparação do desempenho preditivo dos modelos de aprendizado de máquina sob diferentes condições de entrada. Por último, ao integrar o Algoritmo de Busca de Pardal (SSA) para otimizar o fator de suavização no GRNN, o estudo explora o impacto dos algoritmos de otimização no desempenho preditivo do modelo GRNN. Experimentos indicam que, dentro dos modelos de aprendizado de máquina estabelecidos, o GRNN demonstra a maior precisão preditiva. Ao classificar a importância das variáveis de sensoriamento remoto através de RF, 18 variáveis significativas de sensoriamento remoto foram selecionadas, o que melhorou a precisão preditiva dos modelos de aprendizado de máquina. A otimização do fator de suavização do GRNN através do algoritmo SSA pode melhorar significativamente a precisão preditiva do modelo GRNN.

ABSTRACT To quickly and accurately assess tea plant growth, this study aims to find a new way to predict the chlorophyll content in tea plant canopies using machine learning. Using remotely piloted aircraft equipped with multispectral cameras, images of tea plantation areas are captured and reflectance from four spectral bands is extracted, leading to the calculation of vegetation indices. Simultaneously, chlorophyll relative content in the tea plant canopies was collected on the ground using a detector. Four models, namely Random Forest (RF), Backpropagation neural network (BPNN), Radial basis function network (RBFN), and General Regression Neural Network (GRNN), were constructed to predict the chlorophyll relative content in tea plant canopies. Subsequently, important remote sensing variables were identified through RF filtering, followed by a comparison of the predictive performance of machine learning models under different input conditions. Lastly, by integrating the Sparrow Search Algorithm (SSA) to optimize the smoothing factor in the GRNN, the study explores the impact of optimization algorithms on the predictive performance of the GRNN model. Experiments indicate that within the established machine learning models, the GRNN demonstrates the highest predictive accuracy. By ranking the importance of remote sensing variables through RF, 18 significant remote sensing variables were selected, which enhanced the predictive accuracy of the machine learning models. The optimization of the GRNN smoothing factor through the SSA algorithm can significantly enhance the predictive accuracy of the GRNN model. Based on a series of experiments, the established RFSSA-GRNN prediction model demonstrates good predictive performance, with an reaching 0.84. growth cameras extracted indices Simultaneously detector , (RF) BPNN, BPNN (BPNN) RBFN, RBFN (RBFN) (GRNN) Subsequently filtering conditions Lastly (SSA 1 selected experiments RFSSAGRNN RFSSA 084 0 84 0.84 (RF (BPNN (RBFN (GRNN 08 8 0.8 0.

Abstract Objective: To explore the relationship between Anion Gap (AG), Albumin Corrected AG (ACAG), and in-hospital mortality of Acute Myocardial Infarction (AMI) patients and develop a prediction model for predicting the mortality in AMI patients. Methods: This was a retrospective cohort study based on the Medical Information Mart for Intensive Care (MIMIC)-III, MIMIC-IV, and eICU Collaborative Study Database (eICU). A total of 9767 AMI patients who were admitted to the intensive care unit were included. The authors employed univariate and multivariable cox proportional hazards analyses to investigate the association between AG, ACAG, and in-hospital mortality; p < 0.05 was considered statistically significant. A nomogram incorporating ACAG and clinical indicators was developed and validated for predicting mortality among AMI patients. Results: Both ACAG and AG exhibited a significant association with an elevated risk of in-hospital mortality in AMI patients. The C-index of ACAG (C-index = 0.606) was significantly higher than AG (C-index = 0.589). A nomo-gram (ACAG combined model) was developed to predict the in-hospital mortality for AMI patients. The nomo-gram demonstrated a good predictive performance by Area Under the Curve (AUC) of 0.763 in the training set, 0.744 and 0.681 in the external validation cohort. The C-index of the nomogram was 0.759 in the training set, 0.756 and 0.762 in the validation cohorts. Additionally, the C-index of the nomogram was obviously higher than the ACAG and age shock index in three databases. Conclusion: ACAG was related to in-hospital mortality among AMI patients. The authors developed a nomogram incorporating ACAG and clinical indicators, demonstrating good performance for predicting in-hospital mortality of AMI patients.

Abstract Background Significant association between bullous pemphigoid (BP) and stroke has been reported. This study aimed to evaluate the level of anti-BP180 antibody in stroke patients to explore the relationship between BP and stroke in their pathogenesis. Methods We collected serum samples from stroke patients and matched controls between February 2019 and June 2020. The anti-BP180 antibody levels were measured by enzyme-linked immunosorbent assay (ELISA). Results A total of 1183 stroke patients including 970 with cerebral infarction (CI), 192 with intracerebral hemorrhage (ICH), 21 with CI and ICH, and 855 controls were enrolled in this study. Anti-BP180 autoantibody values were significantly higher in stroke patients than in controls (p < 0.001). Anti-BP180 autoantibody-positive rates were 12.51% (148) in stroke patients and 4.68% (40) in controls (p < 0.001, OR = 2.65). In anti-BP180 autoantibody-positive subjects, the values were significantly higher in stroke patients than in controls (p < 0.001). However, only 10 (6.76%) stroke patients and 3 (7.5%) controls had high values (> 100 RU/mL) (p = 0.87). Stratified analysis showed that anti-BP180 antibody positive rates were independent of age, sex, and stroke subtypes in the stroke group. Positive rates in patients with both CI and ICH were nearly two times higher than those in patients with either CI or ICH alone (p = 0.11, OR = 1.94). Study limitations This study had a limited sample size and lacked quantitative criteria for stroke severity. Conclusions Anti-BP180 antibody values and positive rates were higher in stroke patients than in controls, suggesting that stroke patients may have higher of developing BP.

Abstract Objective: This study aimed to perform a meta-analysis to investigate the diagnostic safety and accuracy of Ultrasound-Guided Core Needle Biopsy (US-CNB) Axillary Lymph Nodes (ALNs) region in patients with Breast Cancer (BC). Methods: The authors searched the electronic databases PubMed, Scopus, Embase, and Web of Science for clinical trials about US-CNB for the detection of ALNs in breast cancer patients. The authors extracted and pooled raw data from the included studies and performed statistical analyses using Meta-DiSc 1.4 and Review Manager 5.3 software. A random effects model was used to calculate the data. At the same time, data from the Ultrasound-guided Fine-Needle Aspiration (US-FNA) were introduced for comparison with the US-CNB. In addition, the subgroup was performed to explore the causes of heterogeneity. (PROSPERO ID: CRD42022369491). Results: In total, 18 articles with 2521 patients were assessed as meeting the study criteria. The overall sensitivity was 0.90 (95% CI [Confidence Interval], 0.87‒0.91; p = 0.00), the overall specificity was 0.99 (95% CI 0.98‒ 1.00; p = 0.62), the overall area under the curve (AUC) was 0.98. Next, in the comparison of US-CNB and US-FNA, US-CNB is better than US-FNA in the diagnosis of ALNs metastases. The sensitivity was 0.88 (95% CI 0.84‒ 0.91; p = 0.12) vs. 0.73 (95% CI 0.69‒0.76; p = 0.91), the specificity was 1.00 (95% CI 0.99‒1.00; p = 1.00) vs. 0.99 (95% CI 0.67‒0.74; p = 0.92), and the AUC was 0.99 vs. 0.98. Subgroup analysis showed that heterogeneity may be related to preoperative Neoadjuvant Chemotherapy (NAC) treatment, region, size of tumor diameter, and the number of punctures. Conclusion: US-CNB has a satisfactory diagnostic performance with good specificity and sensitivity in the preoperative diagnosis of ALNs in BC patients.

Abstract Using UPLC and PDA detector, the fingerprints of Dendrobium devonianum and Dendrobium officinale produced in the Longling area of Yunnan Province, China were obtained quickly and efficiently, and 26 common peaks in Dendrobium devonianum and Dendrobium officinale samples were obtained by automatic peak matching through the “Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System”. The relative peak areas of the common peaks were analyzed by PCA using R, and the results showed that Dendrobium devonianum and Dendrobium officinale could be well distinguished by PCA, which was consistent with the analysis results of OPLS-DA. The results fully demonstrate that Dendrobium devonianum and Dendrobium officinale grown in the same area can be effectively distinguished by using the method of common peaks combined with stoichiometry. The VIP value of the 13 common peaks is greater than 1.0, which has a significant contribution to the difference and it was differential marker in Dendrobium devonianum and Dendrobium officinale. At the same time, normal-phase silica gel column chromatography was used to separate and purify the compounds that are related to the common peaks, and a total of 7 compounds were identified, among which eupatolide and isoschaftoside belong to differential markers and characteristic compounds in Dendrobium devonianum and Dendrobium officinale, which have good biological health care activity. The successful identification of Dendrobium devonianum and Dendrobium officinale in Longling area of Yunnan Province and the discovery of related differential markers play an important role in the further research and development of Dendrobium devonianum as a new food raw material and its products. detector efficiently 2 Chinese System.

Objetivo: Estabelecer um modelo de carga de intensidade fixa para o treinamento de velocidade na resposta visual do atleta em voleibol. Métodos: Este trabalho seleciona vários jogadores de vôlei como objetos de pesquisa, divididos aleatoriamente em dois grupos (grupos de treinamento regular e grupos experimentais). O grupo experimental teve o diferencial de ser submetido a um protocolo treinamento de velocidade de resposta visual baseado no treinamento de rotina. Estatísticas matemáticas foram empregadas para analisar a velocidade de reação dos atletas e a capacidade defensiva contra a rede. Resultados: As qualidades analisadas, principalmente velocidade de movimento, velocidade de balanço, agilidade e resistência para balanço rápido e movimento rápido mostraram um diferencial significativo após a intervenção. A velocidade de resposta concentrou-se no centro de equilíbrio corporal. A resistência para a velocidade foi incrementada pelos membros inferiores. Após o treinamento da velocidade de reação visual, a capacidade do grupo experimental de enfrentar os ataques sobre a rede foi estatisticamente superior (P<0,05). Conclusão: O treinamento da velocidade de reação dos jogadores de vôlei pode ser aprimorado com o protocolo proposto. Os jogadores de vôlei devem reforçar o treinamento da velocidade de reação em seu treinamento diário afim de uma melhor capacidade de atuação próxima à rede.

ABSTRACT Introduction: Volleyball is a team sport where winning the confrontation at the net largely determines characteristics. Volleyball players must constantly strive to improve team cooperation, defensive ability, and speed skills to improve their ability to perform over the net. Objective: Establish a fixed intensity load model for speed training on the athlete's visual response in volleyball. Methods: This paper selected several volleyball players as research subjects, randomly divided into two groups (regular training and experimental groups). The experimental group was subjected to a visual response speed training protocol based on routine training. Mathematical statistics were employed to analyze the athletes’ reaction speed and defensive ability against the net. Results: The qualities analyzed, mainly movement speed, swing speed, agility, and endurance for fast swing and fast movement, showed a significant differential after the intervention. The speed response was concentrated in the center of body balance. The lower limbs increased the endurance for speed. After visual reaction speed training, the experimental group's ability to cope with attacks on the net was statistically superior (P<0.05). Conclusion: The proposed protocol can improve the reaction speed training of volleyball players. Volleyball players should reinforce reaction speed training daily to perform better close to the net.

RESUMO: A planta de eucalipto libera substâncias químicas alelopáticas no ambiente principalmente através dos óleos essenciais volatilizados das folhas. Este estudo teve como objetivo discutir a composição dos óleos foliares de algumas variedades com sete anos de idade como Eucalyptus pellita (E. pel), Eucalyptus camaldulensis (E. cama), Eucalyptus grandis (E. gra), Eucalyptus dunni (E. dun ), Eucalyptus saligna (E. sal) e E. grandis × E. urophylla (E. gra× E. uro) e E. grandis × E. urophylla (E. gra × E. uro(três )). Também pretendeu-se determinar o mecanismo alelopático e os tipos de componentes químicos que desempenham o papel principal. O óleo essencial foi obtido por hidrodestilação e analisado pelo método de Cromatografia Gasosa-Espectrometria de Massa (GC-MS). Para determinar o efeito da alelopatia, experimentos de germinação de sementes foram realizados em diferentes concentrações (10-100 mL/L) do óleo foliar de E. Gra × E. uro (OE) e dos componentes majoritários. As sementes de trigo germinadas pela adição de 1,8-cineol foram usadas para determinar a atividade da α-amilase. Além disso, a expressão de mRNA de α-amilase em sementes também foi estudada.: A principal classe química do óleo essencial foi o monoterpeno oxigenado; O 1,8-cineol (20,2-67,5%) apresentou o maior teor. Outras substâncias que eram de alto teor e onipresentes incluíam α-pineno (0,3-21,8%), α-terpineol (0,44-19,24%) e borneol (0,81-3,05%). Os quatro constituintes químicos e o OE influenciaram a germinação e o crescimento das três plantas. Entre eles, o 1,8-cineol exibiu o efeito inibitório mais forte. A atividade de α-amilase das sementes de trigo tratadas com 1,8-cineol diminuiu significativamente. Evidências moleculares sugeriram que o 1,8-cineol diminuiu a expressão do gene α-amilase (AMY).

ABSTRACT: The Eucalyptus plant releases allelopathic chemicals into the environment mostly through the essential oils volatilized from the leaves. This study discussed the composition of the leaf oils of few seven-year-old varieties like Eucalyptus pellita (E. pel), Eucalyptus camaldulensis (E. cama), Eucalyptus grandis (E. gra), Eucalyptus dunni (E. dun), Eucalyptus saligna (E. sal), and E. grandis × E. urophylla (E. gra×E. uro) and three-year-old E. grandis × E. urophylla (E. gra × E. uro (three)). It determined the allelopathic mechanism and the types of chemical components playing the leading role. Essential oil was obtained by hydrodistillation and analyzed by the Gas Chromatography-Mass Spectrometry (GC-MS) method. In order to determine the effect of allelopathy, seed germination experiments were carried out at different concentrations (10-100 mL/L) of the E. Gra × E. uro leaf oil (EO) and the major components. The wheat seeds germinated by adding 1,8-cineole were used to determine the activity of α-amylase. Moreover, the mRNA expression of α-amylase in seeds was studied. The major chemical class in the essential oil was oxygenated monoterpene; 1,8-cineole (20.2-67.5%) displayed the highest content. Other substances that were high in content and ubiquitous included α-pinene (0.3-21.8%), α-terpineol (0.44-19.24%), and borneol (0.81-3.05%). The four chemical constituents and EO influenced the germination and growth of the three plants. Among them, 1,8-cineole exhibited the strongest inhibitory effect. The α-amylase activity of the 1,8-cineole-treated wheat seeds had decreased significantly. Molecular evidence suggested that 1,8-cineole decreased the α-amylase gene (AMY) expression.

A series of novel betulin-28-hydrazone derivatives (7a-7o) were synthesized. All compounds were evaluated for their in vitro cytotoxicities in four human carcinoma cells (HepG2, MCF-7, HCT-116 and A549). Among them, compound 7l displayed the most potent cytotoxicity with an IC50 (concentration of the tested compound that inhibits 50% of cell growth) value of 7.37 ± 0.38 μM against MCF-7 cells. The preliminary cellular mechanism studies indicated that compound 7l could induce MCF-7 cells apoptosis. The above findings indicated that compound 7l may be used as a lead compound for antitumor agents with improved efficacy.

Abstract Introduction: The objective of this study was to investigate the effect of mivacurium in the application of fast-track anesthesia for transthoracic device closure of ventricular septal defects (VSDs) in children. Methods: The data of 108 children who underwent transthoracic device closure of VSDs from December 2018 to June 2020 were recorded and analyzed. All children were divided into group M (mivacurium group, n=55) and group C (cisatracurium group, n=53) according to the different muscle relaxant drug used. Results: No statistically significant differences in general preoperative data, intraoperative hemodynamic changes, or the incidence of adverse reactions were noted between the two groups (P>0.05). However, the intubation condition rating of children in group M was better than that in group C. The onset time, duration of clinical action and recovery index of the muscle relaxant, postoperative mechanical ventilation duration, and length of intensive care unit stay in group M were significantly lower than those in group C (P<0.05). Conclusion: It is safe and feasible to use mivacurium as a muscle relaxant in children undergoing fast-track cardiac anesthesia during transthoracic device closure of VSDs.

Abstract Background: Postoperative cognitive dysfunction is widely recognized as severe postoperative central nervous dysfunction and has a significant impact on the ’patient’s physical and mental health. Methods: Postoperative models of tibial fracture in aged rats were established, including the control group, model group, CCL11 protein injection group, and saline injection group. Morris water maze test was used to detect the behavioral characteristics of rats. Enzyme-Linked Immunosorbent Assay was used or determine the content of CCL11 and CXCL10. Immunofluorescence staining was used to detect the distribution of CD14+CD163+macro-phages in colon tissues and CD11b+CCR3+microglia cells in hippocampal tissues. Western blot analyzed NOX1 and STAT3 expression in hippocampus tissues. Results: Water maze test results confirmed severe cognitive impairment in CCL11 rats. The content of CCL11 and CXCL10 in the CCL11 group was much higher than that of the model group. The distribution of macrophage and microglia cells in the CCL11 model group was greater than that in the model group and the saline group. The expression of NOX1 and STAT3 in the CCL11 group was higher compared with the model group. Conclusion: Abnormal macrophage function and excessive CCL11 secretion were observed in the rats with lower limb fractures after surgery. Postoperative central inflammation in rats with lower limb fracture induced postoperative cognitive dysfunction through the gut-brain axis molecular mechanism.
