Combining melt s.irring method.with in-s.tu technology to prepare compos.tes.is.pres.nted. By the melt s.irring method.net or nearnet s.ape prod.cts.can be fabricated. In-s.tu formation of the reinforcement in the metallic matrix by liquid.s.lid.exothermic chemical reaction can ins.re that the interface between the reinforcement and.the matrix is.clean. Thus.the compos.tes.excellent in properties. s.mple in manufacture, lower in cos. can be gained.

Good.nutrition plays.a crucial role in maintaining a balanced.lifes.yle. The beneficial effects.of nutrition have been found.to counteract nutritional d.s.urbances.with the expand.d.us. of nutraceuticals.to treat and.manage card.ovas.ular d.s.as.s. cancer, and.other d.velopmental d.fects.over the las. d.cad.. Flavonoid. are found.abund.ntly in plant-d.rived.food. s.ch as.fruits. vegetables. tea, cocoa, and.wine. Fruits.and.vegetables.contain phytochemicals.like flavonoid., phenolics. alkaloid., s.ponins. and.terpenoid.. Flavonoid. can act as.anti-inflammatory, anti-allergic, anti-microbial(antibacterial, antifungal, and.antiviral) antioxid.nt, anti-cancer, and.anti-d.arrheal agents. Flavonoid. are als. reported.to upregulate apoptotic activity in s.veral cancers.s.ch as.hepatic, pancreatic, breas., es.phageal, and.colon. Myricetin is.a flavonol which is.naturally pres.nt in fruits.and.vegetables.and.has.s.own pos.ible nutraceutical value. Myricetin has.been portrayed.as.a potent nutraceutical that may protect agains. cancer. The focus.of the pres.nt review is.to pres.nt an upd.ted.account of s.ud.es.d.mons.rating the anticancer potential of myricetin and.the molecular mechanis.s.involved.therein. A better und.rs.and.ng of the molecular mechanis.(s. und.rlying its.anticancer activity would.eventually help in its.d.velopment as.a novel anticancer nutraceutical having minimal s.d. effects.
