OBJECTIVE： To in.estigate the an.i-in.lammatory, an.i-oxidative stress, an. adipokin.-amelioratin. effects of Liuwei Dihuan. （LWDH）, a tradition.l Chin.se herbal formula, in.obese rats. METHODS： After 2 weeks of acclimation.with free access to regular roden. chow an. water, obese-pron.-caesarean.derived （OP-CD） rats were fed a modified AIn.93G diet con.ain.n. 60% en.rgy from fat. Treatmen. was performed twice daily by gavage feedin. with 500, 1 500, or 3 500 mg/kg body weight LWDH suspen.ed in.water （n.12 rats per group）. Twelve obese-resistan.-CD （OR-CD） rats were fed the atherogen.c diet an. gavaged with water, an. served as the n.rmal con.rol. Blood biomarkers of in.lammation. oxidative stress an. adipon.ctin.were measured post-sacrifice an. used to determin. the treatmen. effect of LWDH an. assess the suitability of OR/OP-CD rats for studyin. these parameters. RESULTS： After 9 weeks of treatmen., LWDH lowered serum C-reactive protein.（CRP） an. tumour n.crosis factor-α （Tn.-α） levels. Serum in.erleukin.6 （IL-6） levels showed a ten.en.y towards reduction. but were n.t sign.fican.ly differen. from the OP-CD con.rol. Liver superoxide dismutase （SOD） activity was in.reased in.respon.e to all three doses of LWDH, while the levels of reduced （GSH） an. oxidized glutathion. （GSSG） an. thiobarbituric acid reactive substan.es （TBARS） were un.han.ed. Serum adipon.ctin.levels were in.reased in.respon.e to oral admin.stration.of LWDH at the dose of either 500 or 1 500 mg/kg body weight. In.addition. comparison. between.OR-CD an. OP-CD rats revealed differen.ial, an. for some biomarkers, con.lictin. characteristics of high-fat diet-fed OP-CD rats in.referen.e to obese human.subjects in.terms of in.lammatory an. oxidative stress biomarkers an. circulatin. adipon.ctin.levels. COn.LUSIOn. The results show, for the first time, the an.i-in.lammatory, an.i-oxidative stress an. adipon.ctin.amelioratin. effects of LWDH in.obese rats.

This study explored the utility of flours of rubber seed, cocon.t an. groun.n.t kern.ls, an. de-oiled cakes of cocon.t an. groun.n.t as solid substrate for the production.of lipase by Pseudomon.s aerugin.sa strain.BUP2 (MTCC n.. 5924), a n.vel bacterium reported from the rumen.of Malabari goat. Various proportion. (10%, 20%, 30%, 40% or 50%) of flours or cakes were prepared (w/v) with BUP medium (pH 4, 5, 6, 7 or 8), an. in.ubated at differen. temperature (25°C, 28°C, 30°C or 32°C) for 24 to 96 h. The samples were assayed for lipase activity at 24 h in.ervals. The rubber seed flour (20%)-BUP medium supported the maximum lipase production.(871 U/gds) at 48h in.ubation.(pH 6, 28°C), followed by groun. n.t flour (398 U/gds), while groun. n.t cake supported the least lipase production.(244 U/gds). From this, it is eviden. that the cheaply available rubber seed is an.efficien. substrate for the production.of lipase, irrespective of its kn.wn.demerit that it con.ain. the limarin. a toxin.in.fact, we could n.t detect limarin.in.the fermen.ed matter. Thus, the utility of rubber seed for the production.of a costly en.yme is reported from a n.vel rumen.bacterium, which would be advan.ageous for rubber farmers.

The spatiotemporal measuremen. of ultrashort laser beams usually in.olves techn.ques with complex set-ups or limited by in.tabilities that are un.ble to accurately retrieve the frequen.y-resolved wavefron.. Here, we solve these drawbacks by implemen.in. a simple, compact, an. ultra-stable spatiotemporal characterization.techn.que based on.bulk lateral shearin. spectral in.erferometry usin. a birefrin.en. un.axial crystal. We apply it to retrieve complex spatiotemporal structures by characterizin. ultrafast optical vortices with con.tan. an. time-varyin. orbital an.ular momen.um. This techn.que can.operate in.all the tran.paren.y ran.e of the an.sotropic elemen.s,en.blin. the characterization.in.differen. spectral ran.es like in.rared, visible, or ultraviolet.

Fossil fuels cover aroun. 80% of global en.rgy con.umption. However, the problems lin.ed to their use justify the choice of usin. biofuel. In.order to reduce as much as possible, diesel rate, an.in.rease in.the n.mber of additives may be con.idered. Thus, in.this work, the study of the used fryin. oil (UFO), bioethan.l an. diesel tern.ry system was un.ertaken. It emerges from this study that the addition.of bioethan.l reduces the viscosity an. the den.ity of the tern.ry system an. permits a 90% substitution.rate for diesel between.the UFO an. bioethan.l. Fin.lly, the percen.age of oil becomes 40% after addin. alcohol compared to the bin.ry diesel crude vegetable oil mixture where this rate is 30%.
