Asian Pacific Journal of Tropical Medicine 2018年第10期11卷 555-561页

作者： Muhammad kashif Dongwook Kim Gonhyung Kim Veterinary Medical Center College of Veterinary Medicine Chungbuk National University

Objective: To find the cytotoxic and apoptotic effects of neem oil extract on the selected cancerous(A-549, PC-3 and DU-145) and noncancerous(NIH3T3 and CCD-18Co) cell ***: Viability and cytotoxic effect induced by the extract was measured by using MTT assay and apoptotic effect of the extract was evaluated by using Hoechst 33342 and propidium iodide dual staining through a fluorescent microscope and activity of caspases 3, 8 and 9 through colorimetric assay kits. Results: The results showed that neem oil extract significantly reduced the viability in all selected cancer cells treated with varying concentrations of extract as compared with untreated cells and had less effect on noncancerous cell lines. It significantly increased the percentage of necrotic and apoptotic cells, and caspases 3, 8 and 9 activities in all cancer cells treated with extract as compared with untreated cells whereas no effect on noncancerous cell lines. It suggested that neem oil extract exerted a higher cytotoxic effect on cancer cells than normal cells and lower concentration induced apoptosis only in cancer *** of the apoptosis-inducing mechanism was through the activation of caspases signaling pathways. Conclusion: Conclusively, it implies that neem oil extract may contain one or more potential agents that can be used as a safe and effective anticancer therapy.

Functional gastrointestinal disorders and gut-brain axis: What does the future hold?

引用

World Journal of Gastroenterology 2019年第5期25卷 552-566页

作者： kashif Mukhtar Hasham Nawaz Shahab Abid Centre of Excellence in Women and Child Health Aga Khan University Department of Medicine Section of Gastroenterology Aga Khan University

Despite their high prevalence, lack of understanding of the exact pathophysiology of the functional gastrointestinal disorders has restricted us to symptomatic diagnostic tools and therapies. Complex mechanisms underlying the disturbances in the bidirectional communication between the gastrointestinal tract and the brain have a vital role in the pathogenesis and are key to our understanding of the disease phenomenon. Although we have come a long way in our understanding of these complex disorders with the help of studies on animals especially rodents, there need to be more studies in humans, especially to identify the therapeutic targets. This review study looks at the anatomical features of the gut-brain axis in order to discuss the different factors and underlying molecular mechanisms that may have a role in the pathogenesis of functional gastrointestinal disorders. These molecules and their receptors can be targeted in future for further studies and possible therapeutic interventions. The article also discusses the potential role of artificial intelligence and machine learning and its possible role in our understanding of these scientifically challenging disorders.

Digitalization has changed the way of information processing, and newtechniques of legal data processing are evolving. Text mining helps to analyze andsearch different court cases available in the form of digital text documents toextract case reasoning and related data. This sort of case processing helps professionals and researchers to refer the previous case with more accuracy in reducedtime. The rapid development of judicial ontologies seems to deliver interestingproblem solving to legal knowledge formalization. Mining context informationthrough ontologies from corpora is a challenging and interesting field. Thisresearch paper presents a three tier contextual text mining framework throughontologies for judicial corpora. This framework comprises on the judicial corpus,text mining processing resources and ontologies for mining contextual text fromcorpora to make text and data mining more reliable and fast. A top-down ontologyconstruction approach has been adopted in this paper. The judicial corpus hasbeen selected with a sufficient dataset to process and evaluate the *** experimental results and evaluations show significant improvements incomparison with the available techniques.

China Communications 2007年第1期4卷 14-27页

作者： kashif Kifayat Madjid Merabti David Llewellyn-Jones School of Computing & Mathematical Sciences Liverpool John Moores UniversityUK.

Key establishment and its management in Wireless Sensor Networks(WSN) is a challenging problem due to its limited resources and disordered structure. Many key management schemes have been developed recently for WSN to provide secure communication between source and destination sensor nodes.A serious threat highlighted in all of these schemes is that of node capture attacks,where an adversary gains full control over a sensor node through direct physical *** capture attacks can also be helpful to an adversary in new attacks like Blackhole and Denial of *** of these proposed key management solutions still suffer from node capture attacks with *** current sensor networks are assumed to be designed for specific applications,having key management protocols strongly coupled to *** future sensor networks are envisioned as comprising heterogeneous devices assisting to a large range of *** achieve this goal,a new application independent approach is needed. In this paper we therefore present a novel,extended version of our previously published Dynamic Group-based Key Establishment(DGKE) protocol. We compare the proposed scheme with existing key management schemes,which shows a significant improvement in resilience against node capture attacks,memory overhead and connectivity.
