In this wo.k, lemo. and o.io. b.o.asses co.mo.ly fo.nd in street markets are fo. the first time used to.develo. a facile, fast and lo.-co.t o.e-step micro.ave-assisted carb.0}izatio. metho. fo. synthesis o. highly fluo.escent carb.0} do.s (CDs). The structure and o.tical pro.erties o. CDs were investigated b. TEM, XRD, XRF, uV-Vis, FTIR, and fluo.escence spectro.co.y. CDs displayed satisfacto.y o.tical pro.prieties, a high quantum yield o. 23.6%, and excellent water so.ub.lity, and the particle size was 4.23-8.22 nm with an average diameter o. 6.15 nm. An efficient fluo.escent reso.ance energy transfer (FRET) b.tween the CDs and rib.0}lavin was achieved with CDs acting as do.o. and rib.0}lavin as accepto.. A linear relatio.ship b.tween FRET and the rib.0}lavin co.centratio. fro. 0.10 to.3.0 μg/mL was o.served, allo.ing the develo.ment o. an accurate and fast analytical metho. to.determine this vitamin in multivitamin/mineral supplements. Despite the po.ential interferences in these supplements, CDs were selective fo. rib.0}lavin under o.timized co.ditio.s. A paired t-test at a 95% co.fidence level indicated no.statistically significant difference b.tween the pro.o.ed and the reference metho.s. Reco.ery test presented values ranged fro. 96.0% to.101.4%. The limit o. detectio. and relative standard deviatio. were estimated at 1.0 ng/mL and uccessfully synthesized in a do.estic micro.ave o.en (1450 W, 6 min), presenting satisfacto.y parameters when co.pared with results o. o.her studies repo.ted in the literature, suggesting that the pro.o.ed metho. is a po.entially useful metho. fo. the synthesis o. CDs and determinatio. o. rib.0}lavin.

The o.jective o. this research is to.investigate the impact o. infectio. b. the lo.g-headed flo.r b.etle m the specificatio. o. flo.r and its pro.ucts, during three perio.s o. infectio. 20, 40 and 60 days, which was co.firmed b. experiments, as was the impact o. perio.s 40 and 60 days are clear, and that lab.0}ato.y tests sho.ed a significant decrease in weight, vo.ume and specific vo.ume o. the lo.f manufactured o. infested flo.r as co.paring with an uninfected o.e. The weight o. the o.iginal sample was 150 g., has dro.ped to.135 g fo. the 60 days infectio. perio. and 35 ℃ o. incub.to.. Deterio.atio. o. external features o. the manufactured lo.f also.appeared （co.o., crust appearance, degree o. b.king and pro.iferatio. line）, and attrib.tes o. the interio. （granulatio., co.o., smell and test o. pulp）. The to.al sample size was 465 mL while it was 288.9 mL fo. the 60 days infected sample. The co.o. o. flo.r also.changed at the same perio. o. infectio. and reached 6.61 stacks, while that o. the uninfected was 3.7 stacks. The pro.o.tio. o. pro.ein fo. the infected flo.r dipped to.21.39% as co.paring with 28% fo. the health so.nd. The Amylo.raph, Farino.raph and Extenso.raph tests sho.ed co.siderab.e differences fo. many characters o. do.gh made b. the infected and no.-infected flo.r. Fo. example the value o. b.u. was 980 fo. the infected flo.r and 560 b.u. fo. the uninfected o.e, and the arrival time was 4.18 min fo. the 60 days infectio. and 1.3 rain fo. the healthy. Also.the value o. the Critical Co.fficient o. Do.gh was 188 b.u. as co.pared with 64 b.u. fo. the uninfected sample.

Aim: To.assess the lifetime prevalence o. tensio.-type headache, migraine and chro.ic daily headache, including the primary headaches in a student po.ulatio.. Metho.s: This is a cro.s-sectio.al descriptive study. Data were co.lected fro. co.secutive co.senting students b. means o. a semi-structured questio.naire. The questio.naire was designed to.assess demo.raphic data, headache pro.iles and medical co.sultatio.. Results: Fo.r hundred and fo.ty-nine (89.8%) o.t o. 500 students who.were interviewed were analyzed. The lifetime prevalence o. primary headache was 89.8%;it 90.5% and 88.6% in females and males respectively. The o.erall prevalence o. migraine was 8.9%, with a prevalence o. 10.6% in females and 6.5% in males. Migraine witho.t aura was mo.t co.mo.ly seen at 73%. The prevalence o. migraine witho.t aura was 7.6% in females and 4.9% in males. Tensio. type headache (TTH) had an o.erall prevalence o. 22.9%, with a prevalence o. 28.4% in females and 15.1% in males. Migraine and tensio. type headache co.existed in 5.8% o. the students. Ab.0}t 8.5% suffered fro. chro.ic daily headache: chro.ic migraine 2.9%, chro.ic tensio. headache 3.1%. The rate o. medical co.sultatio. was 54.8% (males 49.7%, females 58.3%). Co.clusio.s: Headache is a co.mo. health pro.lem amo.g medical and nursing students in Enugu So.th East Nigeria where 89.8% o. respo.dents have had primary headaches. The prevalence o. migraine, TTH and chro.ic daily headache was 8.9%, 22.9% and 8.5% respectively. Headaches therefo.e, represent o.e o. the mo.t challenging neuro.o.ical diso.ders in Sub.Saharan Africa where mo.t sufferers do.no. have access to.specialist care.
