Abstract Objective: To determine whether peripheral blood parameters have any predictive value for all-frequency Sudden Sensorineural Hearing Loss (SSNHL). Methods: We chose 78 individuals with all-frequency SSNHL who had been admitted to our department. They were divided into two groups: the effective group and the ineffective group. In patients with all-frequency SSNHL, the prognostic variables, including peripheral blood tests and clinical traits, were examined by a logistic regression analysis. In addition, the predictive value was carried out. Results: The effective rate of all-frequency SSNHL was 61.5%. Pre-treatment hearing level and the proportion of patients with diabetes were both significantly lower in the effective group than in the ineffective group (p = 0.024 and 0.000, respectively). The levels of fibrinogen and C-reactive protein were also significantly different between the two groups (p = 0.001 and 0.025, respectively). Pre-treatment hearing level and fibrinogen level both significantly impacted the prognosis of all-frequency SSNHL (p = 0.032 and 0.002, respectively), according to a logistic regression analysis. Furthermore, the prognosis was significantly predicted by both fibrinogen level and pre-treatment hearing level (p = 0.001 and 0.0002, respectively). The receiver operating characteristic curve showed that the fibrinogen level had a sensitivity of 85.4% and a specificity of 60.0% for predicting the prognosis of all-frequency SSNHL. Conclusion: For the prognosis of all-frequency SSNHL, the fibrinogen level can be regarded as a useful predictor. The level of C-reactive protein, however, does not have a significant prognostic effect on predicting all-frequency SSNHL. Therefore, more attention should be devoted to the level of fibrinogen in the acute period of all-frequency SSNHL. Level of Evidence: 4.

Abstract Background: Isoliquiritigenin (ISL) presents antitumor effects against melanoma cells. It is known that various circular RNAs (circRNAs) are involved in the development of melanoma. Therefore, the present study aims to investigate the molecular mechanisms of ISL and circ_0002860. Methods: Circ_0002860, microRNA-431-5p (miR-431-5p) and member RAS oncogene family (RAB9A) were detected through reverse transcription-quantitative polymerase chain reaction (RT-qPCR) assay. Cell viability was examined via cell counting kit-8 assay. The proliferation ability was assessed using colony formation assay. Cell apoptosis and cell cycle were determined by flow cytometry. Transwell assay was used for detection of migration and invasion. Western blot was conducted for protein analysis. Target binding was confirmed via dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. In vivo research was performed through xenograft tumor assay. Results: Circ_0002860 was downregulated by ISL in melanoma cells. ISL-induced inhibitory effects on cell proliferation, cell cycle progression, migration and invasion were alleviated by circ_0002860 overexpression. MiR-431-5p was a target of circ_0002860. Circ_0002860 eliminated the ISL-induced tumor inhibition via sponging miR-431-5p in melanoma cells. Circ_0002860 elevated the RAB9A level by targeting miR-431-5p. The function of ISL was related to miR-431-5p/RAB9A axis in melanoma progression. Tumor growth was reduced by ISL in vivo through downregulating circ_0002860 to regulate miR-431-5p and RAB9A levels. Conclusion: The current data indicates that ISL suppressed cell malignant progression of melanoma via targeting the circ_0002860/miR-431-5p/RAB9A pathway.

Abstract Objective Osteoarthritis is a condition characterized by articular cartilage degradation. The increased expression of β1,4-Galactosyltransferase-I (β1,4-GalT-I) in the articular cartilage of osteoarthritis patients was related to an inflammatory response. The aim of this study was to elucidate the role of β1,4-GalT-I in osteoarthritis. This study aimed to determine the function of 1,4-GalT-I in osteoarthritis. Methods The osteoarthritis mouse model with the destabilization of the medial meniscus was established by microsurgical technique. Pathological changes in articular cartilage were observed by hematoxylin and eosin staining and safranin O-fast green staining. Quantitative real-time polymerase chain reaction, western blot, and enzyme-linked immunosorbent assays were used to observe mRNA and protein expression, respectively. RNA interactions were verified by a luciferase reporter assay. SA-β-Gal staining was used to assess chondrocyte senescence. Immunofluorescence staining was conducted to observe the localization of Nuclear Factor-kappaB (NF-κB). Results β1,4-GalT-I and microRNA-15a (miR-15a) show high and low expression in the articular cartilage of osteoarthritis, respectively. MiR-15a inhibits the mRNA translation of β1,4-GalT-I. β1,4-GalT-I promotes extracellular matrix degradation, senescence, and NF-κB activation in IL-1β-stimulated chondrocytes, which can be reversed by overexpression of miR-15a. Intra-articular injection of microRNA-15a ameliorates cartilage degeneration by inhibiting β1,4-GalT-I and phosphorylation of NF-κB in vivo. Conclusion The authors clarified that the miR-15a/β1,4-GalT-I axis inhibits the phosphorylation of NF-κB thereby inhibiting extracellular matrix degradation and senescence in chondrocytes to alleviate cartilage degeneration in osteoarthritis. MiR-15a and β1,4-GalT-I may serve as potentially effective targets for the future treatment of osteoarthritis.

RESUMO: A biossíntese é a única fonte de amido de batata que é uma importante matéria-prima para o processamento de alimentos, amido modificado e energia de biomassa. No entanto, não está claro sobre a evolução da síntese do amido com o desenvolvimento do tubérculo na batata. O presente estudo teve como objetivo avaliar as diferenças nas propriedades de síntese e gelatinização do amido de tubérculos de batata com diferentes teores de amido. Em relação às cultivares de médio e baixo teor de amido, as cultivares de alto teor de amido apresentaram expressão do gene SBEII, atividade enzimática AGPase e SSS e teor de amido total significativamente maiores após o estágio intermediário de acúmulo de amido, bem como menor tamanho médio dos grânulos de amido durante todo o processo de desenvolvimento do tubérculo, maior temperatura de colagem antes dos estágios finais de crescimento do tubérculo e menor temperatura de colagem após o estágio intermediário de acúmulo de amido. A análise de trilha mostrou que, após o estágio intermediário de acúmulo de amido, os efeitos na gelatinização do amido de cultivares com alto, médio e baixo teor de amido representaram a atividade da enzima de síntese de amido> acúmulo de amido> distribuição de grânulos de amido> expressão gênica de enzima de síntese de amido; expressão gênica de enzima de síntese de amido > atividade da enzima de síntese de amido> acúmulo de amido> distribuição de grânulos de amido; expressão gênica da enzima de síntese de amido> distribuição de grânulos de amido> atividade de síntese de amido> acúmulo de amido, respectivamente. No estudo, as fases existentes na biossíntese do amido do tubérculo de batata, e a qualidade do amido e seu processo de formação foram diferentes entre as variedades com diferentes teores de amido. As descobertas podem contribuir para a aplicação de amido e as indústrias de batata.

ABSTRACT: Biosynthesis is the only source of potato starch which is an important raw material for food processing, modified starch and biomass energy. However, it is not clear about the evolution of starch synthesis with tuber development in potato. The present study evaluated the differences of starch synthesis and gelatinization properties of potato tubers with different starch content. Relative to cultivars of medium and low starch content, cultivars of high starch content showed significantly higher SBEII gene expression, AGPase and SSS enzyme activity, and total starch content after middle stage of starch accumulation, and had smaller average starch granule size during whole process of tuber development, and had higher pasting temperature before late stages of tuber growth, and had lower pasting temperature after middle stage of starch accumulation. Path analysis showed that, after middle stage of starch accumulation, effects on starch gelatinization of cultivars with high, medium and low starch content represented starch synthesis enzyme activity > starch accumulation > starch granule distribution > starch synthesis enzyme gene expression, starch synthesis enzyme gene expression > starch synthesis enzyme activity > starch accumulation > starch granule distribution, starch synthesis enzyme gene expression > starch granule distribution > starch synthesis enzyme activity > starch accumulation, respectively. In the study, phases existed in the starch biosynthesis of potato tuber, and the starch quality and its formation process were different among varieties with different starch content. The findings might contribute to starch application and potato industries.

Abstract To investigate the effect of corosolic acid treatment on erectile function in metabolic syndrome induced rat model. Fifty male 3-week-old SD rats were fed a high fat and high sugar diet. Six months later, metabolic variables were determined. Metabolic syndrome induced erectile function (MED) rats were confirmed by an apomorphine test. Then MED rats were treated with corosolic acid daily by oral gavage for 4 weeks. To evaluate erectile function, intracavernosal pressure (ICP)/mean arterial blood pressure (MAP) ratio was measured. Thiobarbituric acid reactive substances assay and dihydroethidium staining were used to assess reactive oxygen species (ROS) level. Protein expressions of gp91phox and eNOS were examined by western blotting and immunohistochemistry. Fasting blood glucose, body weight, total cholesterol and insulin were markedly increased in metabolic syndrome rats compared with those of the control rats (p < 0.05). The ratios of max ICP/MAP and area under curve (AUC)/MAP was markedly reduced in MED rats compared with the control rats (p < 0.05). The concentration of cyclic guanosine mono-phosphate (cGMP) and the expression of eNOS were significantly decreased in MED rats compared with the control group (p < 0.05). Moreover, ROS level and the expression of gp91phox were significantly increased in MED rats. Treatment with corosolic acid reversed these changes (each p < 0.05). Corosolic acid reduces the level of ROS, ameliorating endothelial dysfunction and improvement of erectile function in MED rats.

Abstract To investigate the function and mechanism of GINS complex subunit 2 (GINS2) in osteoblast and osteoclast in steroid-induced osteonecrosis of the femoral head (SINFH). Clinical specimens were collected from 40 cases of SINFH patients and 40 cases of control patients. Then, SINFH mouse model was built. Immediately, osteoblasts and osteoclasts were induced and differented from the pre-osteoblast cell line MC3T3-E1 and the mononuclear macrophage cell line RAW264.7 of mice, respectively. The qRT-PCR assay was used for detecting the expressions of GINS2, p53 and growth arrest and DNA damage 45A (GADD45A). The cytoactive, proliferation and apoptosis of osteoblasts and osteoclasts of SINFH mice were measured by tartaric acid phosphatase staining, CCK-8 and Annexin V-FITC/PI dual staining, respectively. GINS2 was up-regulated while p53/GADD45A was down-regulated in femoral tissues in SINFH patients and mice. GINS2 was down-regulated while p53 and GADD45A were up-regulated in osteoblasts of SINFH mice, which presented opposite trends in osteoclasts formations. GINS2 decreased osteoblasts activities and increased osteoclasts activities, inhibited apoptosis and promoted proliferation in osteoblasts and osteoclasts via p53/GADD45A pathway. GINS2 affects activity/differentiation, apoptosis and proliferation of osteoblast and osteoclast in steroid-induced osteonecrosis of the femoral head by regulating p53/GADD45A signaling pathway.

Abstract This study investigated the hyperspectral reflectance response of time series generated during oven drying to changes in the moisture content of potato tubers. Seventeen preprocessing methods were used to eliminate the influence of spectral noise on the spectral characteristic curve. Algorithms such as CatBoost, LightGBM, and XGBoost are used to obtain the first 40 effective characteristic spectra of hyperspectral images, which reduces the redundancy of data and improves the prediction accuracy. The water content prediction model of potato tubers was established by using the selected characteristic bands. The results showed that the combined model based on Lasso and XGBoost algorithm had the strongest prediction ability. The best model is MF-Lasso-XGBoost, which has R2 value of 0.8908, Rmse of 0.0610, Mdae of 0.0389, and R2cv of 0.8448. This research can provide reference for the detection of potato moisture content and theoretical basis for the development of crop moisture detector.

Abstract In this study, the physicochemical properties of walnut (Juglans regia L.) oils collected from different sites in Khyber PakhtoonKhwa (KPK), Pakistan were investigated. The obtained walnut oils showed variation in viscosity, surface tension, density, acid, saponification, and iodine values. The oil obtained from the Madyan (Sample E) showed the lowest density (0.981 g/cm3), surface tension (34.76×10-3 N/m), viscosity (15.0595 cp) saponification values 84.15 (mg KOH/g of oil) and acid value 3.5 (mg KOH per gram oil) amongst all. The physicochemical properties of all the oils were also compared to olive oil (standard) where sample E showed similarities in such properties compared to olive oil. Moreover, higher concentrations of oleic acid (41 %) and linoleic acid (9 %) were detected in the walnut oil of sample E in GC/MS analysis. The similarities of walnut oil obtained from Madyan to that of standard (olive oil) thus affirm it as best quality oil and suitable for food processing purposes.

Abstract To evaluate the effect of medical nutritional therapy (MNT) combined with low glycaemic index (LGI) formula at breakfast for 4 weeks on the glycaemic control of patients with type 2 diabetes mellitus (T2DM). Ninety-six participants were recruited and randomly equally divided into two groups. The intervention group was offered with 40g LGI formula at breakfast adjusted according to MNT, and the control group with regular MNT. After 4 weeks, fasting blood glucose, glycated albumin (GA), insulin, C-peptide levels and metabolic index were compared between the two groups. Compared to the intervention group, the total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and the change of FBG (–0.64 ± 1.4 vs. 0.3 ± 2.2; p < 0.05) and 2h-PBG (–1.8 ± 3.6 vs.0.8 ± 3.2; p < 0.01) in the control group were significantly decreased. The LGI formulations, having a significant effect on controlling glucose and lipid metabolism, could be used as a non-pharmacological intervention for T2DM self-management.

The goal of this study was to identify potential transcriptomic markers in pediatric septic shock prognosis by an integrative analysis of multiple public microarray datasets. Using the R software and bioconductor packages, we performed a statistical analysis to identify differentially expressed (DE) genes in pediatric septic shock non-survivors, and further performed functional interpretation (enrichment analysis and co-expression network construction) and classification quality evaluation of the DE genes identified. Four microarray datasets (3 training datasets and 1 testing dataset, 252 pediatric patients with septic shock in total) were collected for the integrative analysis. A total of 32 DE genes (18 upregulated genes; 14 downregulated genes) were identified in pediatric septic shock non-survivors. Enrichment analysis revealed that those DE genes were strongly associated with acute inflammatory response to antigenic stimulus, response to yeast, and defense response to bacterium. A support vector machine classifier (non-survivors vs survivors) was also trained based on DE genes. In conclusion, the DE genes identified in this study are suggested as candidate transcriptomic markers for pediatric septic shock prognosis and provide novel insights into the progression of pediatric septic shock.

Abstract: The great potential of crowdsourcing contest is bringing the issue of how to sustain solvers’ participation intention to be a hot topic in research and practice. This study uses the framework of Expectation-confirmation model to explain solvers’ continuance intention. Due to the uncertainties inherent in crowdsourcing contest, trust, a salient psychological belief, should be taken into account with the Expectation-confirmation model framework to predict solvers’ continuance intention. In addition, the intensive demand of intelligence and competition indicate interaction and fairness as two crucial factors for solvers to achieve expectation, thus suggesting that they may have influence on the confirmation level. Corresponding to these challenges, this study integrates platform trust, interaction, and perceived fairness into an extended Expectation-confirmation model to examine solvers’ continuance intention. Using a sample of 306 solvers, empirical results show that satisfaction, perceived benefits, and platform trust, which are positively associated with confirmation, are three significant antecedents of solvers’ continuance intention. Confirmation is further found to be significantly determined by interaction and perceived fairness. These findings provide some implications in both theory and practice for understanding the process of triggering sustained intention with an Expectation-confirmation model framework in crowdsourcing contest.

RESUMO OBJETIVO: Explorar o efeito do tratamento com uma abordagem anterior do intervalo neurovascular médio para fraturas de cisalhamento coronal da porção distal do úmero. METODOLOGIA: Este estudo prospectivo incluiu duas pacientes do sexo feminino de 30-64 anos de idade, com idade média de 47 anos. As fraturas foram causadas por quedas de bicicleta. O tempo entre a lesão e a operação foi de 1-2 dias, com um intervalo de tempo médio de 1,5 dias. Duas pacientes com cisalhamento coronal da porção distal do úmero foram tratadas com redução aberta e fixação interna utilizando a abordagem anterior do intervalo neurovascular. RESULTADOS: Não houve complicações neurológicas e vasculares intra e pós-operatórias, nem complicações ou infecções, e a fratura foi unida. Após 12 meses da cirurgia, as pacientes retornaram ao trabalho sem dor e com uma amplitude normal de movimento de rotação do antebraço e cotovelo. Os raios-X revelaram excelente união das fraturas, sem sinais de ossificação heterotópica e sem artrite traumática. De acordo com as diretrizes da clínica Mayo para avaliação da função do cotovelo, uma pontuação de 100 é considerada excelente. CONCLUSÃO: A aplicação da abordagem anterior do intervalo neurovascular do cotovelo no tratamento de uma fratura de cisalhamento da superfície articular da porção distal do úmero, especificamente da tróclea do úmero, pode reduzir o desgaste do tecido mole.

SUMMARY OBJECT: To explore the treatment effect of the anterior medial neurovascular interval approach to coronal shear fractures of the distal humerus. METHODS: This prospective study included two female patients who were 30-64 years old, with a mean age of 47 years. Fractures were caused by falling from a bicycle. The time between the injury and operation was 1-2 days, with a mean time interval of 1.5 days. Two patients with coronal shear fracture of the distal humerus were treated with open reduction and internal fixation using anterior neurovascular interval approach. RESULTS: There were no intraoperative and postoperative neurological and vascular complications or infections, and the fracture was united. At 12 months after the surgery, the patient returned to work without pain, and with a normal range of motion for elbow and forearm rotation. The X-rays revealed excellent fracture union, no signs of heterotopic ossification, and no traumatic arthritis. According to Mayo's evaluation standards for elbow function, a score of 100 is excellent. CONCLUSIONS: The application of the anterior neurovascular interval approach of the elbow in the treatment of shear fracture of the articular surface of the distal humerus, particularly the trochlea of the humerus, can reduce the stripping of the soft tissue.
