文摘Plant-based milks are on the rise due to an increased awareness of their sustainability and health benefits.Currently,dairy milk is the most nutritionally complete beverage,but it suffers from the presence of indigestible lactose and allergenic proteins.Coconut milk has been around for a long time,but its application is limited due to a perceived lack of specific nutrients,high saturated fat levels,and low acceptability.Recent evidence indicates,however,that the saturated fat and other plant-based components found in coconut milk are good for metabolic outcomes and brain health.The conversion of coconut milk to yoghurt will further improve its functionality by boosting its existing nutritional qualities.In this article,the nutritional value of coconut milk,as well as its potential downsides,its application as yoghurt,and suggestions for enhancing its nutritional functionality will be examined.

文摘Consumers are increasingly demanding natural colorants that are safe and offer health benefits.In addition to their ornamental characteristics,Kanzan cherry(KC)blossoms present a promising source of red-hued natural colorants and functional bioactive substances.This research utilized distilled water to extract KC petals(KCP)and their ground powders(KCPP)under varying temperatures(30℃–90℃)and times(30–180 min).The total monomeric anthocyanins(TMAC)and total phenolics(TPC)in the extracts were evaluated via the pH differential and Folin–Ciocalteu methods.Antioxidant capacities were assessed by DPPH free radical scavenging ability and reducing power.Results indicated that the optimal extraction of TMAC and TPC from KCP occurred at 90℃ for 30 min,and the resulting extracts exhibited the highest antioxidant activities among all tested temperatures and durations.Compared to different particle sizes,the finest KCPP generally produced extracts with the highest TMAC,TPC,and antioxidant activity,due to enhanced mass and heat transfer.When compared with the acidified alcohol method,hot water extraction resulted in 68.23%and 71.41%TMAC yields for petals and powders,respectively,while TPC levels were similar or higher.TMAC or TPC showed a significantly positive correlation(p<0.01)with the antioxidant activities.These findings demonstrate that hot water extraction is a viable and environmentally friendly alternative for phytochemical recovery from KC.Additionally,elevated extraction temperature and pH accelerated anthocyanin degradation and shortened its half-life,while higher pH also lowered the activation energy,enthalpy,entropy,and Gibbs free energy.Thus,red–orange KC extracts with rich bioactivity may serve as promising ingredients for functional foods having acidic pH levels.

文摘The valorization of Amazonian wood residues into active chemical compounds could be an eco-friendly,cost-effective and valuable way to develop wood preservative formulations to enhance the decay and termite resistance of low-durable wood species.Wacapou(Vouacapoua americana.,Fabaceae)is a well-known Guianese wood spe-cies commonly used in local wood construction due to its outstanding natural durability,which results from the presence of a large panel of extractives compounds.In addition,its industrial processing generates large amounts of residues.Wacapou residues were extracted by maceration using four different solvents(water/ethanol,ethyl acetate,hexane and dichloromethane/methanol),separately and successively.The yield of each extractive fraction was determined,and their chemical compositions were analyzed by Liquid Chromatography-Mass Spectrometry(LC-MS).Ethyl acetate led to the highest extraction yield,and the active compounds were identified in the obtained extractive fraction.In this sense,the fungicidal and termite-repellent properties of these extractives were then tested using a screening laboratory(with temperate and tropical microorganisms),according to the solution concentration(1%,2.5%,5%,8%and 10%).Finally,Virola michelii Heckel wood samples(low durable species)were impregnated with the 8%concentration solution.The impregnated wood samples were then exposed to a soil bed test.The results highlighted that the nature of the solvent used during wood maceration affects the con-tent of the obtained extractive fractions.Ultra-Performance Liquid Chromatography–High-Resolution Mass Spectrometry(UHPLC-HRMS)analyses showed the influence of extraction parameters on the nature of the extracted molecules.Wacapou extracts(from ethyl acetate maceration)showed good anti-fungal and anti-termite activities.Additionally,the concentration in extractives had an impact on the anti-termite activity level for Reti-culitermesflavipes and Cryptotermes sp.Formulations based on Wacapou extractives showed a good potential for valorization in eco-friendly preservatives,aiming to confer better durability to local low-durability wood species.

文摘BACKGROUND Ischemic heart disease ranks among the foremost contributors to mortality worldwide.Myocardial infarction injury poses a prevalent challenge in current therapies.Studies have shown that mesenchymal stem cell transplantation increases cytokine release,reduces myocardial cell necrosis,and improves left ventricular function;thus,it can be used to understand protective mechanisms.Fat extract(FE)derived from mesenchymal stem cell therapy contains high levels of paracrine factors.AIM To study the effects of FE on myocardial injury and its mechanism of action.METHODS A mouse model of myocardial infarction and a hypoxic model of neonatal rat cardiomyocytes(CMs)were established to evaluate the effects of FE.RESULTS FE exhibited an inhibitory effect on CM apoptosis and improved left ventricular function.This protective effect of FE on CMs was mediated,in part,by the activation of the phosphatidylinositol 3-kinase/protein kinase B/mechanistic target of rapamycin signaling pathway.CONCLUSION Our findings showed that FE could be a new treatment to protect CMs in ischemic heart disease.
文摘Since Google introduced the concept of Knowledge Graphs(KGs)in 2012,their construction technologies have evolved into a comprehensive methodological framework encompassing knowledge acquisition,extraction,representation,modeling,fusion,computation,and storage.Within this framework,knowledge extraction,as the core component,directly determines KG quality.In military domains,traditional manual curation models face efficiency constraints due to data fragmentation,complex knowledge architectures,and confidentiality protocols.Meanwhile,crowdsourced ontology construction approaches from general domains prove non-transferable,while human-crafted ontologies struggle with generalization deficiencies.To address these challenges,this study proposes an OntologyAware LLM Methodology for Military Domain Knowledge Extraction(LLM-KE).This approach leverages the deep semantic comprehension capabilities of Large Language Models(LLMs)to simulate human experts’cognitive processes in crowdsourced ontology construction,enabling automated extraction of military textual knowledge.It concurrently enhances knowledge processing efficiency and improves KG completeness.Empirical analysis demonstrates that this method effectively resolves scalability and dynamic adaptation challenges in military KG construction,establishing a novel technological pathway for advancing military intelligence development.

文摘Background:Neurological disorders(NDs),including ischemic stroke(IS),Parkinson’s disease(PD),and Alzheimer’s disease(AD),are major contributors to global morbidity and mortality.Boswellia extract has demonstrated neuroprotective properties,yet a comprehensive systematic review assessing its efficacy remains absent.This study aims to evaluate the efficacy of Boswellia extract in treating NDs,with a particular focus on its effects in AD and its potential for long-term neurorestoration,thereby supporting further investigation into Boswellia’s therapeutic role in ND management.Methods:A systematic literature search was performed in PubMed,Web of Science,ScienceDirect,and Google Scholar for English-language studies published up to March 2024.Eighteen studies met the inclusion criteria and were included in the meta-analysis.The study protocol was registered on PROSPERO(CRD42024524386).Eligible studies involved rodent models of IS,PD,or AD with post-operative interventions using Boswellia extract.Data extraction focused on mechanisms of action,dosages,treatment durations,and therapeutic outcomes.Studies were excluded if they involved non-ND models,combined treatments,or had incomplete data.Two researchers independently conducted literature screening and data extraction.Statistical analyses were conducted using Stata(version 17)and RevMan(version 5.4),employing fixed or random-effects models based on heterogeneity assessments.Result s:Boswellia extract significantly improved the mean effect size for NDs(ES=1.28,95%CI(1.05,1.51),P<0.001).Specifically,it reduced cerebral infarct volume in IS(SMD=−2.87,95%CI(−3.42,−2.32))and enhanced behavioral outcomes in AD(SMD=3.26,95%CI(2.07,5.14))and PD(SMD=5.37,95%CI(3.93,6.80)).Subgroup analyses revealed that Boswellia extract exhibited superior efficacy in AD when administered orally and via intra-cerebroventricular injection.Long-term treatment with Boswellia extract suggested potential neurorestorative effects.Additionally,Boswellia extract was more effective than its monomeric constituents,highlighting its promising role in ND treatment.Conclusion:Boswellia extract demonstrates significant neuroprotective effects across various NDs,particularly in AD and in promoting long-term neurorestoration.These findings support the need for further research into Boswellia’s potential as a therapeutic agent in the management of neurological disorders.
文摘AIM:To investigate the long-term outcomes in acute primary angle closure(APAC)patients treated with lens extraction(LE)surgery and to identify risk factors for glaucomatous optic neuropathy(GON).METHODS:In this longitudinal observational study,detailed medical histories of APAC patients and comprehensive ophthalmic examinations at final followup were collected.Logistic regression analysis was performed to identify predictors of blindness.Univariate and multivariate linear regression analyses were conducted to determine risk factors associated with visual outcomes.RESULTS:This study included 39 affected eyes of 31 subjects(26 females)with an average age of 74.1±8.0y.At 6.7±4.2y after APAC attack,2(5.7%)eyes had bestcorrected visual acuity(VA)worse than 3/60.Advanced glaucomatous visual field loss was observed in 15(39.5%)affected eyes and 5(25.0%)fellow eyes.Nine affected eyes(23.7%)had GON,and 11(28.9%)were blind.Six(15.4%)affected eyes and 2(9.1%)fellow eyes had suspicious progression.A significantly higher blindness rate in factory workers compared to office workers.Logistic regression identified that worse VA at attack(OR 10.568,95%CI 1.288-86.695;P=0.028)and worse early postoperative VA(OR 13.214,95%CI 1.157-150.881;P=0.038)were risk factors for blindness.Multivariate regression showed that longer duration of elevated intraocular pressure(P=0.004)and worse early postoperative VA(P=0.009)were associated with worse visual outcomes.CONCLUSION:Despite LE surgery,some APAC patients experience continued visual function deterioration.Lifelong monitoring is necessary.Target pressure and progression rates should be re-evaluated during follow-up.
