The Light Emitting Diode (LED) lights are extensively utilized in the cultivation of several plant species, especially horticultural plants due to their lower power consumption and higher luminous efficiency compared to the conventional fluorescent lights. The aim of this review paper is to examine the potential of LED technology as it relates to plant lighting in greenhouses and other horticultural environments. It also desires to give an in-depth study of the advantages of LED lighting on plant development, yield, the production of secondary metabolites, and defense mechanisms. Horticultural lighting might undergo a revolution because LEDs are used in solid-state lighting, which would be a tremendous advancement after decades of research. LEDs may be used in a variety of horticulture lighting applications, such as tissue culture lighting, controlled environment research lighting, supplementary lighting, and photoperiod lighting for greenhouses. The primary impacts of light colors on plant performance are shown by the spectrum effects of LEDs as an independent source of light, together with the diverse sensitivity of many plant species and alternatives. LED light influences performance of enzyme, gene expression, cell wall formation, plant defense and postharvest quality. The spectrum reactions are mediated by the ambient lighting in a greenhouse, which also indicates a strong relationship between the additional supplementary lighting and changing environmental factors. LEDs are growing further to become cost-effective for even large-scale horticulture lighting applications as light output increases and device expenditures decrease.</p></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"7 ","pages":"Article 100184"},"PeriodicalIF":5.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590262824000108/pdfft?md5=45bc5c6f3ec8a6e97e7afac6a34cf132&pid=1-s2.0-S2590262824000108-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139737873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents AutoTarget, a novel computational pipeline designed to identify disease-associated druggable targets by applying node representation learning to protein–protein interaction (PPI) networks. AutoTarget uses node2vec + for node classification, incorporating neighborhood context and structural equivalence in PPI networks derived from the STRING database. Data from the Therapeutic Target Database (TTD) and DisGeNET were integrated to identify known drug targets and gene-disease associations, respectively. Each protein is embedded into a 128-dimensional vector space, capturing local network structures and enabling the identification of structurally equivalent proteins. A Naïve Bayes classifier, trained on these embeddings, achieved a recall of 0.90 and an F1 score of 0.79 in predicting potential drug targets. AutoTarget identified 3,979 novel potential druggable target proteins out of 19,333 proteins in the PPI network, which were mapped to 23,363 diseases using DisGeNET. This creates a comprehensive resource for disease-specific drug target exploration. Case studies on triple-negative breast cancer and obesity demonstrated AutoTarget’s capability to identify both established and emerging targets, such as CD44, MAPK3, and GIP. Visualization of embedding vectors using t-SNE revealed clear separations between functional protein families, including nuclear proteins, growth factor receptors, and the G proteins within the kinase proteins. This supports the method’s ability to capture biologically relevant information. However, limitations were noted, including the inability to distinguish between different types of disease-associated proteins based solely on network features. Overall, this study advances the application of machine learning and network theory for identifying druggable targets across a wide range of diseases.

However, in mainstream wastewater with a low-strength ammonium, obtaining partial nitritation (PN) for the anammox process can be challenging and often result in NO<sub>3</sub><sup>–</sup> accumulation. The recently proposed partial denitrification (PD), which reduces NO<sub>3</sub><sup>–</sup> back to NO<sub>2</sub><sup>–</sup>, can provide NO<sub>2</sub><sup>–</sup> for anammox. For a successful PD-anammox (PD/A), it is crucial to efficiently cultivate PD bacteria (PDNB) and maintain a balance between the activities of PDNB and anammox bacteria (AnAOB). In this study, an efficient PDNB enrichment was cultivated for a long period of 400 days in a sequential batch reactor (SBR) by feeding it with acetate (300 mg COD/L) and nitrate (100 mg NO<sub>3</sub><sup>–</sup>-N/L) at an exchange ratio of 50 %.

Despite its potential, a comprehensive understanding of its anticancer effects and mechanisms of action remains elusive.</p><p>The aim of this review is to present novel insights into the anticancer effects of FX, shedding light on previously unexplored molecular mechanisms and its synergistic potential with established chemotherapeutic agents.</p><p>A comprehensive search was conducted employing databases like PubMed/MedLine, Scopus, and Web of Science to aggregate relevant pharmacological experimental studies. The results of the studies showed that FX exhibits anticancer activity against various cancer types, including breast, colorectal, and lung cancer, through multiple pathways: cell cycle arrest, apoptosis induction, and inhibition of angiogenesis. Additionally, FX potentiates the effects of existing chemotherapeutic agents, making it a potential candidate for combination therapies. The evidence suggests that FX possesses considerable anticancer properties, acting through diverse molecular mechanisms; the heterogeneity of study designs and the limited number of clinical trials make it hard to conclude. Further in-depth studies, particularly randomized controlled trials, are essential for validating FX's efficacy and for paving the way for its integration into standard cancer treatment regimens; additional research is needed to explore its pharmacokinetics, safety profile, and potential synergistic effects with existing chemotherapeutics.</p></div>","PeriodicalId":52676,"journal":{"name":"Current Research in Biotechnology","volume":"7 ","pages":"Article 100203"},"PeriodicalIF":5.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590262824000297/pdfft?md5=e6441fb7a74e44a4bcbbb15179e39e74&pid=1-s2.0-S2590262824000297-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140308691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
