The aim of this study was to discover useful clinical features that can help physicians to identify these patients.METHODS: We reviewed the discharge notes from two hospitals and identifi ed all patients who had a diagnosis of infected aneurysms of the thoracoabdominal aorta and iliac arteries between July 2009 and December 2013. Eighteen patients, aged from 41 to 93, were reviewed. Only 6 patients were diagnosed accurately in their fi rst visit to our ED.RESULTS: Most patients had at least one underlying illness, and it took 1 to 30(9.9±6.5) days for physicians to diagnose their infected aneurysm. Localized pain and fever were the two most commonly presented symptoms. The majority(92%) of isolated microorganisms were gram-negative bacilli, including Salmonella spp, Klebsiella pneumoniae, and Escherichia coli. Two of the 3 patients who underwent non-operative therapy died, and all of the patients who underwent a combination of medical and operative therapies survived.CONCLUSION: We suggest that physicians liberally use computed tomography scans on patients with unknown causes of pain and inflammatory processes. A combination of surgical and medical treatments is indicated for all patients with infected aortic and iliac aneurysms.展开更多

The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.展开更多

文摘Objective Oral squamous cell carcinoma(OSCC)is an aggressive cancer with a high mortality rate.San-Zhong-Kui-Jian-Tang(SZKJT),a Chinese herbal formula,has long been used as an adjuvant therapy in cancer clinical practice.Although its therapeutic effects and molecular mechanisms in OSCC have been previously elucidated,the potential interactions and mechanisms between the active phytochemicals and their therapeutic targets are still lacking.Methods The present study employed network pharmacology and topology approaches to establish a“herbal ingredients–active phytochemicals–target interaction”network to explore the potential therapeutic targets of SZKJT-active phytochemicals in the treatment of OSCC.The role of the target proteins in oncogenesis was assessed via GO and KEGG enrichment analyses,and their interactions with the active phytochemicals of SZKJT were calculated via molecular docking and dynamic simulations.The pharmacokinetic properties and toxicity of the active phytochemicals were also predicted.Results A total of 171 active phytochemicals of SZKJT fulfilled the bioavailability and drug-likeness screening criteria,with the flavonoids quercetin,kaempferol,and naringenin having the greatest potential.The 4 crucial targets of these active phytochemicals are PTGS2,TNF,BCL2,and CASP3,which encode cyclooxygenase-2,tumor necrosis factor(TNF),BCL-2 apoptosis regulator,and caspase-3,respectively.The interactions between phytochemicals and target proteins were predicted to be thermodynamically feasible and stable via molecular docking and dynamics simulations.Finally,the results revealed that the IL-6/JAK/STAT3 pathway and TNF signaling via NF-κB are the two prominent pathways targeted by SZKJT.Conclusion In summary,this study provides computational data for in-depth exploration of the mechanism by which SZKJT activates phytochemicals to treat OSCC.
文摘The intricate interplay between natural compounds like curcumin and the gut microbiome has gained significant attention in recent years due to their potential therapeutic implications in various health conditions.Curcumin,a polyphenolic compound derived from turmeric,exhibits diverse pharmacological properties,including anti-inflammatory,antioxidant,and anticancer effects.Understanding how curcumin modulates gut microbiota composition and function is crucial for elucidating its therapeutic mechanisms.This review examines the current literature on the interactions between curcumin and the gut microbiome.A systematic search of relevant databases was conducted to identify studies investigating the effects of curcumin on gut microbial diversity and abundance.Key findings from studies exploring curcumin's efficacy in neurological disorders,gastrointestinal diseases,and metabolic dysfunction are synthesized and discussed.Studies have demonstrated that curcumin supplementation can modulate gut microbiota composition and function,leading to beneficial effects on gut health and homeostasis.Mechanisms underlying curcumin's therapeutic effects include immune modulation,neuroprotection,and inflammation regulation.However,challenges such as poor bioavailability and safety concerns remain significant hurdles to overcome.The interactions between curcumin and the gut microbiome hold promise for therapeutic interventions in a diverse range of health conditions.Further research is needed to optimize curcumin formulations,improve bioavailability,and address safety concerns.

文摘Mesenchymal stem cells(MSCs)are known for their ability to differentiate into various cell lineages,including osteoblasts(bone-forming cells),and for their significant paracrine effects.Among their secreted products,exosomes have gained considerable attention as nanoscale carriers of bioactive molecules such as non-coding RNAs(ncRNAs).These ncRNAs,including microRNAs,long ncRNAs,and circular ncRNAs,are critical regulators of gene expression and cellular functions.Moreover,MSC-derived exosomes not only offer advantages such as targeted delivery,reduced immunogenicity,and protection of cargo material,but also carry ncRNAs that have therapeutic and diagnostic potential in bone-related disorders.Emerging evidence has highlighted the role of MSC-derived exosomal ncRNAs in osteogenesis,bone remodeling,and intercellular signaling in the bone microenvironment.This review consolidates recent research on the role of MSC-derived exosomal ncRNAs in maintaining bone homeostasis and bone-related disorders via various signaling pathways and epigenetic modifications.Furthermore,we explore the therapeutic potential of MSC-derived exosomal ncRNAs as biomarkers and therapeutic targets.This comprehensive review offers key insights into the regulatory roles of MSC-derived exosomal ncRNAs in bone biology and their clinical significance in bone-related diseases.

文摘Melanomas are aggressive cancers,with a high rate of metastatic disease.Cutaneous(CM)and uveal(UM)melanomas are intrinsically different diseases,and most cell death inducers effective for CM do not function for UM.This is primarily due to the fact the eye is an immunologically privileged organ,and it fails to achieve the efficacy of immune checkpoint inhibitors(ICIs)comparable to that for CM.However,approaches utilizing specific melanomaassociated antigens are being developed for metastatic forms of CM and UM.The most promising to date are gp100 and tyrosinase related protein 1(TYRP1),primarily for the design of targeting chimeric molecules and for autologous T-/NK-cell products with a chimeric antigen receptor.The difference in the mutational profile of apoptosis-related genes in CM and UM also makes counterproductive the use of the same drugs re-activators of the intrinsic pathway of apoptosis.Therefore,the discovery of novel pathways of regulated cell death such as ferroptosis and cuproptosis may help in the development of new drugs for melanomas resistant to already available inducers of regulated cell death.Here we consistently discuss the latest advances in the therapy of melanomas,and above all-UM,which is classified as an orphan disease.
文摘Hexavalent chromium,when present in high concentrations,causes a serious threat to the ecosystem.This can lead to severe ecological damage and persistent environmental issues,making it a significant concern for long-term sustainability.Thus,there is a strong need for high-performing adsorbents to remove high concentrations of Cr(VI)from the environment.In the present study,Citrus Limetta peels were utilised to produce pristine biochar,which was treated with iron oxides to generate magnetic biochar and modified with chitosan,sodium alginate,and pectin to produce respective modified biochar.Among all five biochars,Chitosan-modified biochar(CMBC)displayed the highest removal efficiency towards Cr(VI)from water with a maximum adsorption capacity of 152.44 mg/g and a removal capacity of 76.22%.Furthermore,adsorption kinetics indicates that the adsorption process is a pseudo-second order-kinetic model with R^(2)and qe of 0.99 and 99 mg/g,respectively.The Langmuir isotherm best describes the adsorption process.After five regenerative cycles,the removal efficiency was maintained at up to 71.80%.This work highlights the remarkable potential of engineered biochar in wastewater treatment.

文摘Global warming and climate change have made food production through conventional agriculture inefficient, and their effects on livestock and crop cultivation are leading to disruptions in the food supply. The troubles are severe in regions suffering from improper land management and unsustainable practices. The Bio-CircularGreen(BCG) economic model, designed to reduce and recycle resources by using environmentally friendly procedures, has been developed. The Azolla plant represents an interesting model for BCG and for enhancing community networks in Southeast Asia(SEA) because it provides multipurpose materials. Azolla can be used for various applications in agriculture such as biofertilizer and animal feed. However, our understanding and utilization of Azolla are limited. Moreover, collaboration among farmers is insufficient to maximize the benefits of Azolla. In this study, we provide a comprehensive review of the role of Azolla in agriculture. We review the main properties of Azolla as biofertilizers, especially regarding rice production and the interaction with cyanobacteria. For livestock, we discuss procedures to use Azolla in animal feed and evaluate the ingredients of the meal. In addition, we discuss product qualities from livestock treated with Azolla in the diet. This review also describes Azolla-based farming, which is designed for efficient land use and promotes nutrient cycling.Hence, we show that the Azolla plant is one of the key factors for farm-based agroecosystem services which can drive sustainable bioresource management in SEA. Moreover, we also propose the potential development of Azolla to improve its properties as a biofertilizer, a functional feed for animals and humans, and a feedstock for bio-oil production.
文摘Objective:To investigate the levels of seminal plasma exosomes and the expression of the SRD5A2 gene in Iraqi men with different types of male infertility(asthenozoospermia,oligozoospermia,and azoospermia),and to explore the regulatory role of selected microRNAs(miRNAs)in the modulation of SRD5A2 gene expression.Methods:A total of 90 male participants were categorized into four groups:asthenozoospermia(n=24),oligozoospermia(n=24),azoospermia(n=18),and normozoospermia(n=24).Seminal plasma exosome levels were quantified using ELISA.RNA,including miRNAs,was extracted,followed by cDNA synthesis.The expression of SRD5A2 mRNA and five selected miRNAs(miR-6090,hsa-miR-5189-5p,miR-23a-5p,miR-1914-3p,and miR-4540)was evaluated using qRT-PCR.Correlation analyses were conducted between exosome levels,miRNA expression,and SRD5A2 expression.Results:Infertile men exhibited significantly lower seminal exosome levels than normozoospermic men(P<0.01).The expression of SRD5A2 mRNA was decreased in asthenozoospermic and oligozoospermic men but elevated in azoospermic men.Elevated levels of hsa-miR-5189-5p,miR-6090,and miR-23a-5p were observed in infertile groups.Correlation analysis revealed a significant negative relationship between these miRNAs and SRD5A2 expression in asthenozoospermic and oligozoospermic men,but a positive correlation in azoospermic men.Exosome levels were also significantly correlated with the expression of these miRNAs,suggesting their role as molecular carriers in regulating gene expression.Conclusions:This study highlights the potential role of seminal exosomes and specific miRNAs in regulating SRD5A2 gene expression among infertile men.The altered levels of exosomes and dysregulated miRNA expression,particularly hsa-miR-5189-5p and miR-6090,may serve as novel biomarkers for the diagnosis and management of male infertility.Further research is warranted to validate these findings and explore their therapeutic implications.
文摘Insulin plays a crucial role in the metabolic priming and proliferation of neural stem cells(NSCs).However,insulin resistance(IR)is associated with impaired NSC proliferation and cognitive dysfunction,which are the hallmarks of psychiatric disorders(PDs).In addition to insulin,de novo lipogenesis(DNL)also plays an essential role in NSC proliferation and function as it supplies fatty acids for membrane phospholipid synthesis and cell signaling.However,enhanced DNL is associated with lipid/fatty acid accumulation,IR,and impaired NSC proliferation.Intriguingly,data from lipidomic studies suggest that DNL could be enhanced before the onset of classical symptoms in patients with PDs.Further,evidence suggests that patients with PDs may develop IR during childhood or before adolescence;therefore,DNL could be enhanced preceding the development of IR.Regarding treatment,while most antidepressants and antipsychotic drugs have been shown to further deteriorate IR and stimulate DNL,various adjunctive drugs/therapies,including chemical,physical,and stem cell therapy,which have shown promising success in treating PDs,reduce DNL while enhancing insulin sensitivity,NSC proliferation,and cognitive function in laboratory animals.Preliminary clinical outcomes and future prospects of these adjunctive drugs/therapies,especially stem cell therapy in treating PDs including schizophrenia and depression,are discussed.

文摘This study was performed to investigate the changes in microbial communities and metabolites during the long-term fermentation of commercially manufactured anchovy sauce.Samples of commercial anchovy sauce were collected from large-scale fermentation tanks with fermentation periods of up to 7.87 years.The complex bacterial community was simplified to two genera,Tetragenococcus and Halanaerobium,after approximately 0.55 years of fermentation.Although genera,such as Saccharomyces,Cladosporium,Candida,and Aspergillus,were relatively dominant,no clear pattern was identified in fungal community analysis.The longitudinal metabolite profile demonstrated that approximately half(55.8%)of the metabolites present in anchovy sauce were produced within a year of fermentation due to rapid fermentation.Despite the static microbial community,the contents of several metabolites including amino acids and biogenic amines changed continuously during the long-term fermentation of anchovy sauce.This study provides novel insights into the changes in microbiota and metabolites in fish sauce produced without any starter inoculation.
文摘Pancreatic cancer(PC)remains a highly lethal malignancy worldwide.Increasing evidence indicates that inflammation is a critical factor in the pathogenesis of pancreatic ductal adenocarcinoma(PDAC).Inflammatory cell infiltration within the PDAC tumor microenvironment promotes tumor growth and metastasis,while both local and systemic chronic inflammation is associated with an elevated risk of developing the disease.Given that the same immune cell populations are involved in mediating both inflammatory and immune responses,there exists a close interrelationship between inflammation and immunity in the context of PDAC.Various studies have reported the relationship between inflammation and PC.This review article provided a comprehensive summary of the roles of erythrocyte sedimentation rate,plasma viscosity,procalcitonin,calprotectin,haptoglobin,serum amyloid A,ferritin,and fibrinogen in the pathophysiological mechanisms underlying PC.
