ASSOCIATION OF DIABETIC MACULAR EDEMA WITH QUALITY OF LIFE IN PATIENTS WITH TYPE 2 DIABETES: The Fushun Diabetic Retinopathy Cohort Study.

PURPOSE: To report the vision-related quality of life in patients with diabetic macular edema (DME) in a population-based study. METHODS: In this cross-sectional study, we analyzed 1,659 subjects with type 2 diabetes. Questionnaires were administered to assess the patient's vision-related quality of life. Diabetic macular edema severity was graded according to the established protocols. A subject's DME score ranged from 1 (no DME in either eye) to 7 (severe bilateral DME) using predefined criteria. RESULTS: Composite 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25) scores for participants with DME were 88.9 (interquartile range [IQR]: 76.2-94.9) compared with 92.0 (IQR: 82.7-96.0) for those without DME ( P < 0.001). Locally weighted scatterplot smoothing plots depicted a consistent decline in composite NEI-VFQ-25 scores corresponding to the escalation of bilateral DME severity: starting from 88.59 for no DME in either eye, progressing through 86.65, 85.83, 85.31, 84.91, 83.85, and culminating at 82.71 for bilateral severe DME. Notably, the locally weighted scatterplot smoothing plots highlighted significant NEI-VFQ-25 composite score reduction at unilateral mild DME (slope m = -1.94). CONCLUSION: Significant changes in vision-related quality of life manifest in the early stage of DME. Therefore, early identification and intervention for these patients are crucial clinical objectives.

Conservation Strategies for Aquilaria sinensis: Insights from DNA Barcoding and ISSR Markers.

The evergreen tree species Aquilaria sinensis holds significant economic importance due to its specific medicinal values and increasing market demand. However, the unrestricted illegal exploitation of its wild population poses a threat to its survival. This study aims to contribute to the conservation efforts of A. sinensis by constructing a library database of DNA barcodes, including two chloroplast genes (psbA-trnH and matK) and two nuclear genes (ITS and ITS2). Additionally, the genetic diversity and structure were estimated using inter-simple sequence repeats (ISSR) markers. Four barcodes of 57 collections gained 194 sequences, and 1371 polymorphic bands (98.63%) were observed using DNA ISSR fingerprinting. The Nei's gene diversity (H) of A. sinensis at the species level is 0.2132, while the Shannon information index (I) is 0.3128. The analysis of molecular variance revealed a large significant proportion of total genetic variations and differentiation among populations (Gst = 0.4219), despite a relatively gene flow (Nm = 0.6853) among populations, which were divided into two groups by cluster analysis. There was a close genetic relationship among populations with distances of 0.0845 to 0.5555. This study provides evidence of the efficacy and dependability of establishing a DNA barcode database and using ISSR markers to assess the extent of genetic diversity A. sinensis. Preserving the genetic resources through the conservation of existing populations offers a valuable proposition. The effective utilization of these resources will be further deliberated in subsequent breeding endeavors, with the potential to breed agarwood commercial lines.

Analysis of the chloroplast genome and phylogenetic evolution of Bidens pilosa.

Chloroplast genomes for 3 Bidens plants endemic to China (Bidens bipinnata Linn., Bidens pilosa Linn., and Bidens alba var. radiata) have been sequenced, assembled and annotated in this study to distinguish their molecular characterization and phylogenetic relationships. The chloroplast genomes are in typical quadripartite structure with two inverted repeat regions separating a large single copy region and a small single copy region, and ranged from 151,599 to 154,478 bp in length. Similar number of SSRs and long repeats were found in Bidens, wherein mononucleotide repeats (A/T), forward and palindromic repeats were the most in abundance. Gene loss of clpP and psbD, IR expansion and contraction were detected in these Bidens plants. It seems that ndhE, ndhF, ndhG, and rpl32 from the Bidens plants were under positive selection while the majority of chloroplast genes were under purifying selection. Phylogenetic analysis revealed that 3 Bidens plants clustered together and further formed molophyletic clade with other Bidens species, indicating Bidens plants might be under radiation adaptive selection to the changing environment world-widely. Moreover, mutation hotspot analysis and in silico PCR analysis indicated that inter-genic regions of ndhD-ccsA, ndhI-ndhG, ndhF-rpl32, trnL_UAG-rpl32, ndhE-psaC, matK-rps16, rps2-atpI, cemA-petA, petN-psbM were candidate markers of molecular identification for Bidens plants. This study may provide useful information for genetic diversity analysis and molecular identification for Bidens species.

Genome-wide characterization of regulator of chromosome condensation 1 (RCC1) gene family in Artemisia annua L. revealed a conservation evolutionary pattern.

BACKGROUND: Artemisia annua is the major source for artemisinin production. The artemisinin content in A. annua is affected by different types of light especially the UV light. UVR8, a member of RCC1 gene family was found to be the UV-B receptor in plants. The gene structures, evolutionary history and expression profile of UVR8 or RCC1 genes remain undiscovered in A. annua. RESULTS: Twenty-two RCC1 genes (AaRCC1) were identified in each haplotype genome of two diploid strains of A. annua, LQ-9 and HAN1. Varied gene structures and sequences among paralogs were observed. The divergence of most RCC1 genes occurred at 46.7 - 51 MYA which overlapped with species divergence of core Asteraceae during the Eocene, while no recent novel RCC1 members were found in A. annua genome. The number of RCC1 genes remained stable among eudicots and RCC1 genes underwent purifying selection. The expression profile of AaRCC1 is analogous to that of Arabidopsis thaliana (AtRCC1) when responding to environmental stress. CONCLUSIONS: This study provided a comprehensive characterization of the AaRCC1 gene family and suggested that RCC1 genes were conserved in gene number, structures, constitution of amino acids and expression profiles among eudicots.

An Acoustic Localization Sensor Based on MEMS Microphone Array for Partial Discharge.

Partial discharge (PD) localization is important for monitoring and maintaining high-voltage equipment, which can help to prevent accidents. In this work, an acoustic localization sensor based on microelectromechanical system (MEMS) microphone array is proposed, which can detect and locate the partial discharge through a beam-forming algorithm. The MEMS microphone array consists of eight commercial MEMS microphones (SPV08A0LR5H-1, Knowles Electronics, IL, USA) with an aperture size of about 0.1 m × 0.1 m, allowing for a small hardware size and low cost. In order to optimize the acoustic performance of the array, a random array topology is designed. The simulation analysis indicates that the designed random topology is superior to several commonly used topologies. In terms of the localization algorithm, a deconvolution method called Fourier-based fast iterative shrinkage thresholding algorithm (FFT-FISTA) is applied. Simulation and experiment results demonstrate that FFT-FISTA used in the proposed acoustic localization sensor has significant advantages over the conventional beam-forming algorithm on spatial resolution and sidelobe suppression. Experimental results also show that the average localization error of the proposed scheme is about 0.04 m, which can meet the demands of practical application.

Comparative chloroplast genome analyses of Amomum: insights into evolutionary history and species identification.

BACKGROUND: Species in genus Amomum always have important medicinal and economic values. Classification of Amomum using morphological characters has long been a challenge because they exhibit high similarity. The main goals of this study were to mine genetic markers from cp genomes for Amomum species identification and discover their evolutionary history through comparative analysis. RESULTS: Three species Amomum villosum, Amomum maximum and Amomum longipetiolatum were sequenced and annotated for the complete chloroplast (cp) genomes, and the cp genomes of A. longipetiolatum and A. maximum were the first reported. Three cp genomes exhibited typical quadripartite structures with 163,269-163,591 bp in length. Each genome encodes 130 functional genes including 79 protein-coding, 26 tRNAs and 3 rRNAs genes. 113-152 SSRs and 99 long repeats were identified in the three cp genomes. By designing specific primers, we amplified the highly variable loci and the mined genetic marker ccsA exhibited a relatively high species identification resolution in Amomum. The nonsynonymous and synonymous substitution ratios (Ka/Ks) in Amomum and Alpinia showed that most genes were subjected to a purifying selection. Phylogenetic analysis revealed the evolutionary relationships of Amomum and Alpinia species and proved that Amomum is paraphyletic. In addition, the sequenced sample of A. villosum was found to be a hybrid, becoming the first report of natural hybridization of this genus. Meanwhile, the high-throughput sequencing-based ITS2 analysis was proved to be an efficient tool for interspecific hybrid identification and with the help of the chloroplast genome, the hybrid parents can be also be determined. CONCLUSION: The comparative analysis and mined genetic markers of cp genomes were conducive to species identification and evolutionary relationships of Amomum.

Injectable and Biodegradable Chitosan Hydrogel-Based Drug Depot Contributes to Synergistic Treatment of Tumors.

Combined therapy provides a more effective method in the treatment of tumors and becomes a research hotspot. To improve treatment outcomes and reduce serious side effects, hydrogel-based local delivery was developed herein to form a drug depot in suit to eliminate tumors. Indocyanine green and imiquimod were coencapsulated in the novel temperature-sensitive chitosan hydrogel. After intratumoral injection of the hydrogel, indocyanine green that accumulated in the tumor area could induce thermal ablation of primary tumors under laser irradiation. In the presence of imiquimod, the immune effects increased the probability of complete ablation of primary tumors and inhibition of metastases. Combined with cyclophosphamide, the enhanced immunological responses would further inhibit tumors and prolong the survival time. In a word, this work offered an excellent local delivery platform that enabled a remarkable combined antitumor strategy and achieved synergistic therapeutic effects.

The protective effect of sinapic acid in osteoarthritis: In vitro and in vivo studies.

The anti-inflammatory effect of sinapic acid (SA) has been reported in several studies. However, whether SA has the same effect on osteoarthritis (OA) has yet to be clearly elucidated. We designed a series of in vitro and in vivo procedures to verify the above conjecture. Compared with controls, SA-pretreated human chondrocytes showed lower levels of interleukin (IL)-1ß-induced IL-6, prostaglandin E2 (PGE2), nitric oxide (NO) and tumour necrosis factor-α (TNF-α) in vitro. Meanwhile, SA could also reverse the degradation of type II collage and aggrecan, as well as the overproduction of matrix metalloproteinase-9 (MMP-9) and matrix metalloproteinase-13 (MMP-13), inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and a disintegrin and metalloproteinase thrombospondin motifs (ADAMTS)-5. Furthermore, activation of nuclear factor κB (NF-κB), which was induced by IL-1ß, was also inhibited by SA through the pathway of nuclear factor-erythroid 2-related factor-2 (Nrf2)/heme oxygenase 1. In vivo, SA could delay the progress of mice OA models. We propose that SA may be applied as a potential therapeutic drug in OA treatment.

Methylation analysis highlights novel prognostic criteria in human-metastasized melanoma.

Melanoma accounts for 90% of the deaths associated with cutaneous neoplasms, and the 5-year survival rate of patients with the advanced stage is about 20%. Many mechanisms are involved in melanoma progression, but dynamic epigenetic changes are likely to be critical contributors, especially for DNA methylation. However, we know little about the methylation events involved in melanoma lymph node metastasis (LNM), a deficit that is of particular concern because it has a growing incidence and mortality. To identify DNA methylated-associated changes involved in the formation of metastatic melanoma, we explored the different methylated genes (DMGs) between primary and LNM melanoma by Illumina Human Methylation 450 K BeadArray GSE44661. By integrating DNA methylation and messenger RNA expression data from The Cancer Genome Atlas database, we identified these DNA methylation biomarkers. Pathway analysis highlighted these DMGs, which were closely related to the carcinogenesis of melanoma, such as cell cycle regulation and RNA transcription process. Furthermore, according to the univariate and multivariate Cox regression analysis, we constructed a four-DMG prognostic signature model, which could precisely predict the outcome of melanoma in a more exact way. In summary, this four-DMG based risk score model successfully predicts the survival of melanoma. It is independent of other clinical characteristics and is good for prognosis prediction.

Effect of puerarin on melanogenesis in human melanocytes and vitiligo mouse models and the underlying mechanism.

Puerarin is the major bioactive ingredient derived from the root of the Pueraria lobata (Willd.), and its antioxidative stress effects have been demonstrated in several previous studies. Moreover, Puerarin can upregulate melanin synthesis and microphthalmia-associated transcription factor (MITF) transcription by increasing cAMP level of intracellular cyclic adenosine monophosphate. Vitiligo is an acquired cutaneous disorder of pigmentation, and the pathogenesis has remained elusive. Current treatment modalities are directed towards achieving repigmentation. In this study, we found that after treating with puerarin at various concentrations of 40 µmol/L, the melanin content of human melanocytes increased significantly and the apparent level of protein and the RNA levels of MITF, tyrosinase (TYR), and tyrosinase-related protein 1 (TRP-1) were also increased. Further, puerarin was shown to inhibit phosphorylation and activation of extracellular signal-regulated kinase 1 and 2 (ERK1/2) without significantly affecting p38 and c-Jun N-terminal kinase phosphorylation. These results demonstrated that puerarin stimulated melanogenesis in human melanocytes via inhibition of ERK1/2 signaling pathways, which leads to upregulation of MITF and TYR as well as TRP-1 subsequently. Additionally, mice vitiligo models with puerarin treatment showed lighter pathological changes. Therefore, we suggested that puerarin might be a potential medicine for vitiligo.

The Protective Effect of Ligustilide in Osteoarthritis: An in Vitro and in Vivo Study.

BACKGROUND/AIMS: Osteoarthritis is a degenerative joint disease characterized by cartilage degeneration and a chondrocyte inflammatory response that induces an inflammatory environment closely linked to extracellular matrix (ECM) degradation. Ligustilide (LIG) is a major component of the herb Radix Angelicae Sinensis, with demonstrated anti-inflammatory effects. To confirm whether LIG has an equally inhibitory effect on inflammation in human osteoarthritis chondrocytes, we performed in vivo and in vitro experiments to validate the above conjectures and determine the relevant mechanisms. METHODS: Quantitative realtime PCR and western blotting were performed to evaluate the expression of MMP-3, MMP-13, ADAMTS-5, iNOS, and COX-2 at both gene and protein levels. An enzyme-linked immunosorbent assay was used to evaluate the levels of other inflammatory factors (PGE2, TNF-α, and IL-6). The PI3K/AKT and nuclear factor kappa B (NF-κB) signaling pathways were also analyzed by western blotting, whereas immunofluorescence was used to assess the expression of collagen II and aggrecan. The in vitro effect of LIG was evaluated by intraperitoneal injection into a mouse osteoarthritis model induced by destabilization of the medial meniscus. RESULTS: LIG lowered the phosphorylation levels of p65, IκBα, and IKKα/ß and suppressed the IL-1ß-induced expression of MMP-3, ADAMTS-5, iNOS, and COX-2 and the inflammatory factors PGE2, TNF-α, and IL-6. LIG markedly decreased IL-1ß-induced degradation of collagen II and aggrecan. In vivo results showed that LIG-treated mouse cartilage showed less damage than the control group; the Osteoarthritis Research Society International (OARSI) score was also lower. LIG further reduced the thickness of the subchondral bone plate and alleviated the synovitis. CONCLUSION: LIG may act as a promising therapeutic agent for osteoarthritis by attenuating IL-1ß-induced inflammation in chondrocytes and ECM degradation via suppression of NF-κB activation by the PI3K/AKT pathway.

An enhanced Monte Carlo outlier detection method.

Outlier detection is crucial in building a highly predictive model. In this study, we proposed an enhanced Monte Carlo outlier detection method by establishing cross-prediction models based on determinate normal samples and analyzing the distribution of prediction errors individually for dubious samples. One simulated and three real datasets were used to illustrate and validate the performance of our method, and the results indicated that this method outperformed Monte Carlo outlier detection in outlier diagnosis. After these outliers were removed, the value of validation by Kovats retention indices and the root mean square error of prediction decreased from 3.195 to 1.655, and the average cross-validation prediction error decreased from 2.0341 to 1.2780. This method helps establish a good model by eliminating outliers. © 2015 Wiley Periodicals, Inc.

Anti-idiotypic nanobody-phage based real-time immuno-PCR for detection of hepatocarcinogen aflatoxin in grains and feedstuffs.

Aflatoxins are a group of extremely toxic small molecules that have been involved in human hepatic and extrahepatic carcinogenesis as causative agents. Herein, we developed a real-time immuno polymerase chain reaction (IPCR) assay for the accurately quantitative detection of aflatoxins in agri-products base on a M13 phage containing aflatoxin anti-idiotypic nanobody and its encoding DNA which was used to design the specific primers. The limit of detection (LOD) of the assay is 0.02 ng/mL, which exhibits a 4-fold improvement over traditional phage ELISA. The developed method was successfully validated with the samples of corn, rice, peanut, and feedstuff, which are major aflatoxin-contaminated agri-products. And the recoveries were from 77.05 to 122.16%. For further validation, the developed assay was also compared with a reference HPLC method for the analysis of aflatoxins in corn and peanuts, and concordant results (R(2) = 0.991) were obtained. In this context, this study provides a novel opportunity to analyze aflatoxins in agri-products.

Nanobody-based enzyme immunoassay for aflatoxin in agro-products with high tolerance to cosolvent methanol.

A phage-displayed library of variable domain of heavy chain of the heavy chain antibody (VHH) or nanobody (Nb) was constructed after immunizing an alpaca with aflatoxin B1 (AFB1) conjugated with bovine serum albumin (AFB1-BSA). Two AFB1-specific nanobodies were selected. The obtained nanobodies were compared to an aflatoxin-specific monoclonal antibody B5 with respect to stability under organic solvents and high temperature. The two nanobodies could bind antigen specifically after exposure to temperatures as high as 95 °C. Besides, the nanobodies showed better or similar tolerance to organic solvents. A competitive ELISA with nanobody Nb26 was developed for the analysis of AFB1, exhibiting an IC50 value of 0.754 ng/mL (2.4 µM), linear range from 0.117 to 5.676 ng/mL. Due to the high tolerance to methanol, sample extracts were analyzed by nanobody-based ELISA without dilution. The recovery from spiked peanut, rice, corn and feedstuff ranged from 80 to 115%. In conclusion, the isolated nanobodies are excellent candidates for immunoassay application in aflatoxin determination.

Biotoxin sensing in food and environment via microchip.

Biotoxin contamination in food and environmental samples has threatened health or life of human and animals. Thus, a rapid lab-independent sensing method for biotoxin determination is urgently required. Microchip sensing system allows a promising rapid and low-cost detection strategy. Herein, the recent development of various microchips, including microfluidic chip and microarray, has been discussed to sense various biotoxins in food and environmental samples (i.e. phytotoxin, animal toxin, marine toxin, and mycotoxin). Microchip can be served as both analyte transportation and sensing platform, via either labeling or labeling-free sensing strategy. Because of its fast sensing time, low sample consumption, ready portability, and high compatibility, it has been extensively employed in biotoxin determination in both academic and industrial circle. With the advances of fabrication strategies and sensing modes, the microchip performance has been dramatically improved, including sensitivity, efficiency, reliability, stability, cost saving, portability. The potential applications can be found wide spread in biotoxin sensing in the near future, while their practical application in real sample need to be addressed.

Pan-cancer investigation of psoriasis-related BUB1B gene: genetical alteration and oncogenic immunology.

Unknown factors contribute to psoriasis' hyperproliferative, chronic, inflammatory, and arthritic features. Psoriasis patients have been linked to an increased risk of cancer, though the underlying genetics remain unknown. Since our prior research indicated that BUB1B contributes to the development of psoriasis, we designed and carried out this investigation using bioinformatics analysis. Using the TCGA database, we investigated the oncogenic function of BUB1B in 33 tumor types. To sum up, our work sheds light on BUB1B's function in pan-cancer from various perspectives, including its pertinent signaling pathways, mutation locations, and connection to immune cell infiltration. BUB1B was shown to have a non-negligible role in pan-cancer, which is connected to immunology, cancer stemness, and genetic alterations in a variety of cancer types. BUB1B is highly expressed in a variety of cancers and may serve as a prognostic marker. This study is anticipated to offer molecular details on the elevated cancer risk that psoriasis sufferers experience.

A High Sensitivity AlN-Based MEMS Hydrophone for Pipeline Leak Monitoring.

In this work, a miniaturized, low-cost, low-power and high-sensitivity AlN-based micro-electro-mechanical system (MEMS) hydrophone is proposed for monitoring water pipeline leaks. The proposed MEMS Hydrophone consists of a piezoelectric micromachined ultrasonic transducer (PMUT) array, an acoustic matching layer and a pre-amplifier amplifier circuit. The array has 4 (2 × 2) PMUT elements with a first-order resonant frequency of 41.58 kHz. Due to impedance matching of the acoustic matching layer and the 40 dB gain of the pre-amplifier amplifier circuit, the packaged MEMS Hydrophone has a high sound pressure sensitivity of -170 ± 2 dB (re: 1 V/µPa). The performance with respect to detecting pipeline leaks and locating leak points is demonstrated on a 31 m stainless leaking pipeline platform. The standard deviation (STD) of the hydroacoustic signal and Monitoring Index Efficiency (MIE) are extracted as features of the pipeline leak. A random forest model is trained for accurately classifying the leak and no-leak cases using the above features, and the accuracy of the model is about 97.69%. The cross-correlation method is used to locate the leak point, and the localization relative error is about 10.84% for a small leak of 12 L/min.

Construction of a novel prognostic model in skin cutaneous melanoma based on chemokines-related gene signature.

Skin cutaneous melanoma, SKCM, is one of the most aggressive treatment-resistant tumours. Despite the fact that the BRAF oncogene and immunological checkpoints such as PD-1/PD-L1 and CTLA-4 have enhanced the therapeutic efficacy of SKCM, the subsequent resistance mechanisms and remedies have raised concerns. Chemokines have a significant role in the immunological milieu of tumor, which may increase the efficacy of checkpoint blockade and serve as a possible therapeutic intervention route. However, there is still no chemokine-based typing and risk model to provide a prognosis and therapeutic efficacy assessment for SKCM patients. In this study, we verified the distinct differences of prognostic stratification as well as immune characteristics between two chemokine-related clusters in SKCM patients. Two clusters of DEGs were discovered to be primarily enriched in B and T cell receptor signaling pathways as well as TNF signaling via NF-kappa-B. Based on 14 prognosis-related DEGs from aforementioned two clusters (CCL8, GBP2, GBP4, SRNG, HLA-DMB, RARRES3, HLA-DQA1, PARP12, APOL3, IRF1, HLA-DRA, UBE2L6, IL2RA and CD38), a chemokine-related 14-gene prognostic model was established. At the same time, researchers explored differences between the low-risk and high-risk groups in clinical traits, the proportion of infiltration of 22 different types of immune cells, and how well medications worked. The risk score model's immunotherapy and prognostic predictions were also confirmed in testing groups. Based on the finding, we can claim that there is a clear link between chemokines and TME in SKCM. The risk score may perform as a trustworthy prediction model, giving therapeutic benefits for both chemotherapy and immunotherapy, as well as being beneficial for clinical decision making in SKCM patients.

Cryptococcosis Inhibits the Immune Response of Dendritic Cells Through the snhg1-miR-145a-3p-Bcl2 Axis.

OBJECTIVES: Dendritic cells are one of the first host cells that cryptococcus encounters. However, the correlations among cryptococcus, dendritic cells, and long noncoding RNA remain unclear. This study was undertaken to investigate the effects of long noncoding RNAs on dendritic cells with cryptococcus infection. MATERIALS AND METHODS: We treated dendritic cells with cryptococcus and then detected expression of CD80, CD86, and major histocompatibility complex class II in dendritic cells with a real-time fluorescent quantitative polymerase chain reaction assay. We used nextgeneration sequencing and bioinformatics analysis to determine the competitive endogenous RNA mechanisms, confirmed via real-time polymerase chain reaction, dual luciferase reporter, and RNA-binding protein immunoprecipitation assays. RESULTS: After treatment of dendritic cells with 1 × 108 CFU/mL cryptococcus for 12 hours, dendritic cell viability was normal, whereas mRNA expression levels of CD80, CD86, and major histocompatibility complex class II in dendritic cells were substantially increased. With next-generation sequencing, we discovered 4 small nucleolar RNA host genes (snhg1, snhg3, snhg4, and snhg16) in cryptococcus-treated dendritic cells compared with wild-type dendritic cells. Bioinformatics analysis combined with real-time polymerase chain reaction led us to speculate that cryptococcus may affect the maturation and apoptosis of dendritic cells by regulating snhg1-miR-145a-3p-Bcl2. Further polymerase chain reaction, dual luciferase reporter, and RNA-binding protein immunoprecipitation experiments revealed that snhg1 acted as a sponge for miR145a-3p to inhibit the expression of miR-145a-3p and that miR-145a-3p promoted the expression of Bcl2 by directly targeting the 3'-UTR of Bcl2. Functional recovery experiments showed that cryptococcus promoted the maturation and apoptosis and inhibited the proliferation of dendritic cells through the snhg1-Bcl2 pathway. CONCLUSIONS: This study lays a foundation for the further understanding of the pathogenic role of snhg1-miR-145a-3p-Bcl2 axis in cryptococcosis.

Simultaneous removal of aflatoxin B1 and zearalenone in vegetable oils by hierarchical fungal mycelia@graphene oxide@Fe3O4 adsorbent.

Physical adsorbents for detoxification are widely used in vegetable oil industry. So far, the high-efficiency and low-cost adsorbents have not been well explored. Here, a hierarchical fungal mycelia@graphene oxide@Fe3O4 (FM@GO@Fe3O4) was fabricated as an efficient adsorbent for simultaneous removal of aflatoxin B1 (AFB1) and zearalenone (ZEN). The morphological, functional and structural characteristics of the prepared adsorbents were systematic investigated. Batch adsorption experiments in both single and binary systems were conducted, and the adsorption behaviours and mechanism were explored. The results indicated that the adsorption process occurred spontaneously and the mycotoxin adsorption could be described as physisorption through hydrogen bonding, π-π stacking, electrostatic and hydrophobic interactions. Due to good biological safety, magnetic manipulability, scalability, recyclability and easy regeneration, FM@GO@Fe3O4 performance is suitable for application as a detoxification adsorbent in vegetable oil industry. Our study addresses a novel green strategy for removing multiple mycotoxins by integrating the toxigenic isolates with advanced nanomaterials.
