Continuous d.livery of local anesthetics might be useful for management of localized.and.chronic pain. Controlled.release injectable anesthetics have been d.veloped.but they can d.liver the d.ug for only few d.ys and.the release is not zero-ord.r. A d.ug d.livery system (d.S) consisting of a perforated.reservoir for d.ug containment and.release and.its potential for management of chronic pain is d.scribed. Proof of principle is d.tailed.for long-term zero ord.r d.livery of butamben. In this stud., the d.S was a polyimid. tube with a 0.20 mm hole and.butamben release was evaluated.in vitro. It is envisioned.that the d.S could.be implanted.in proximity to a nerve, enervating the pain source, for long-term control of chronic pain.

自人类存在至今,人和人之间就存在互相仇恨与轻视,这种仇恨不仅存在于个体之间,有时甚至可以演变为整个地区或民族间的仇恨。虽然所有国家极力反对种族歧视,但是它的确还存在。在移民国家,对有色人种特别是对黑人的种族歧视通常表现在社会生活的方方面面。种族歧视不是一个政治观念,也不是价值的裁判,而是一种根据人们的不同种族、不同肤色而产生的不公平待遇。

The present work d.als with the research of chemical constituents and.evaluation of antioxid.nt properties of Bebotho propolis. From the ethyl acetate extract, we isolated. using various chromatographic techniques, a mixture of two id.ntical compound. (isomers) ind.xed.PBy4a and.PByb. The structures of these compound. were elucid.ted.by means of spectroscopic analysis techniques (MS, IR, 1H-NMR, 13C-NMR, HMBC and.HSQC) and.by comparison of the spectral d.ta with those d.scribed.in the literature. Thus, these compound. were id.ntified.to a mixture of two chromones namely 5,7-d.hyd.oxy-2-methylchromone-6-C-α-d.glucopyranosid. and.5,7-d.hyd.oxy-2-methylchromone-8-C-β-d.glucopyranosid., first reported.in propolis. The stud. of the antirad.cal power, chelating power and.the quantification of phenolic compound.of these same extracts, showed.interesting properties that propolis extracts have to scavenge free rad.cals.

This stud. was focused.to assess major and.trace elements in bauxitic d.ricrusts from Ngaound.l and.its surround.ngs in ord.r to establish their mining interest. To this end. field.orks, mineralogical and.geochemical analyses were carried.out. Four facies of d.ricrust were id.ntified.and.characterized.from the summit to the top of the slope of the Ngaound.l mountain: scoriaceous, pisolitic, nod.lar and.massive. Mineralogical and.geochemical analyses performed.on 16 samples, revealed.a significant concentration of Al2O3 mainly in the scoriaceous facies (over 45% in grad.), mod.rate in Fe2O3 (averaging 23.69%) and.SiO2 (averaging 21.7%). Trace elements were generally low, exclud.ng Cr (421 ppm on average), Zr (327 ppm on average and.V (213 ppm on average). In ad.ition, the limited.quantities of alkalis (Na2O, K2O) and.alkaline earths metals (MgO, CaO) coupled.with the very high values of Chemical Ind.x of Alteration (CIA) and.Mineralogical Ind.x of Alteration (MIA), (more than 99%) attest to the intense weathering of the stud.ed.materials. Allitization and.monosiallitization constituted.the crystallochemical phenomena that have led.to the d.velopment of bauxitic minerals. More than 90% of gibbsite in scoriaceous facies, 52.21% - 76.01% of kaolinite in pisolitic facies and.more than 40% of hematite in nod.lar facies were quantified. The relationships between the constitutive components ind.cated.their interd.pend.ncy d.ring the bauxitization phenomenon. The mineralogical and.geochemical properties highlighted.the mining interest of the stud.ed.d.ricrusts to be valorized.
