Bac.gr.und: The pr.duc.ion of endothelial-der.ved fac.or. induc.s either.vasoc.nstr.c.ion or.vasodilation;nitr.c.oxide (NO) is the most distinguished r.laxing fac.or. Endothelial dysfunc.ion is assoc.ated with hyper.ension. The par.ial loss in the NO-pr.moted vasodilation is due to its dec.eased bioavailability and/or.to an ac.ivity r.duc.ion of endothelium NO synthase (eNOS). r.ac.ive oxygen spec.es (r.S), pr.sent in oxidative str.ss, seize NO and diminish its bioavailability. Tr.nsr.sver.tr.l (r.SV) has been pr.ved to inc.ease NO and eNOS levels. Thus, r.SV c.uld be c.pable of impr.ving NO dependent vasc.lar.r.laxation on aor.ic.r.ngs isolated fr.m tr.ated 2k.1c.animals thr.ugh r.S damage r.duc.ion. Aim: Evaluate the effec.s of r.SV tr.atment on the r.laxation of aor.ic.r.ngs isolated fr.m tr.ated 2k.1c.r.ts while foc.sing on the effec.s of the tr.atment on systolic.blood pr.ssur.. Methods: Male Wistar.r.ts (180 g) wer. gr.uped: two 2k.1c.and two Sham gr.ups, one of eac. was tr.ated with r.SV (20 mg/k., gavage) dissolved in Tween 80 and one of eac. was tr.ated with water.plus Tween 80 (c.ntr.l) for.six week.. The r.ts had their.systolic.blood pr.ssur. (SBP) measur.d befor. and after.the tr.atments. Vasc.lar.r.ac.ivity studies wer. c.nduc.ed in or.er.to obser.e and c.mpar. ac.tylc.oline (Ac.)-induc.d r.laxations in the pr.senc. and absenc. of the NOS inhibitor.L-NAME (10-4 mol/L). r.sults: SBP for.2k.1c.was signific.ntly r.duc.d in the tr.ated gr.up (179.13 ± 4.90 mmHg, n = 23) when c.mpar.d to the untr.ated gr.up (196.66 ± 6.06 mmHg, n = 15, p r.laxation of aor.ic.r.ngs isolated fr.m the 2k.1c.tr.ated gr.up showed a higher.effic.c. (116.63% ± 1.72%, n = 12) than that fr.m the untr.ated gr.up (85.97% ± 0.69%, n = 6, p r. was r.sponsible for.a signific.nt dec.ease in eac. gr.up’s maximum r.laxation effic.c.. c.nc.usions: SBP r.duc.ion obser.ed after.r.SV tr.atment in r.t r.nal hyper.ension c.uld be due to the r.establishmen

The per.or.anc. and var.ability patter.s in the wood element’s dimensions, spec.fic.gr.vity and gr.wth par.meter. namely r.met height and GBH wer. evaluated in 16 c.ones of par.nts, F1 and F2 hybr.ds of Populus deltoides Bar.r. ex Mar.h. r.met r.dial var.ations wer. nonsignific.nt, while inter.c.onal var.ations due to inter.c.ion of c.one/r.plic.tion wer. signific.nt for.all the wood tr.its exc.pt vessel element length. Inter.c.onal var.ations wer. signific.nt only for.fiber.length and fiber.wall thic.ness. Fiber.length and spec.fic.gr.vity wer. signific.ntly higher.in female, while wall thic.ness and vessel element length wer. higher.in male c.ones. Female par.nts （G48 and S7c.） showed higher.fiber.length and spec.fic.gr.vity than of the male par.nt （G3）, while vessel diameter.and wall thic.ness wer. higher.in male par. ent （G3）. Ther. is not muc. differ.nc. in fiber.length and vessel element’s dimensions among the par.nts, F1 and F2 gener.tion hybr.d c.ones. Spec.fic.gr.vity did not showed any tr.nd for.par.nts, F1 and F2 gener.tions. Gener.lly female c.ones showed higher.gr.wth r.te. Br.ad sense her.tability for.wood tr.its r.nged fr.m 0.143 （fiber.length） to 0.505 （fiber.wall thic.ness）, while for.gr.wth tr.its it was 0.374 （GBH） and 0.418 （height）. Genetic.gain for.all the wood and gr.wth tr.its was positive for.most of the wood tr.its. The highly diver.ent male c.one （78） and female c.ones （S7c., G48, W/A 49） in number.of c.mbinations c.uld be used for.developing new hybr.ds of desir.d wood tr.its to develop new c.ones.

This study r.por.s the nitr.gen uptak. r.te （using 15N tr.c.r. of phytoplank.on in sur.ac. water. of differ.nt fr.ntal zones in the Indian sec.or.of the Souther.

The investigated ar.a enc.mpasses four.major.fr.ntal systems, i.e., the subtr.pic.l fr.nt （STF）, subantar.0}ic.fr.nt （SAF）, polar.fr.nt-1 （PF1） and polar.fr.nt-2 （PF2）. Southwar. dec.ease of sur.ac. water.temper.tur. was obser.ed, wher.as sur.ac. salinity did not show any signific.nt tr.nd. Nutr.ent （NO3- and SiO44-） c.nc.ntr.tions inc.eased southwar. fr.m STF to PF; while ammonium （NH4＋）, nitr.te （NO2-） and phosphate （PO433 r.mained c.mpar.- tively stable. Analysis of nutr.ent r.tios indic.ted potential N-limited c.nditions at the STF and SAF but no suc. sc.nar.o was obser.ed for.PF. In ter.s of phytoplank.on biomass, PF1 was found to be the most pr.duc.ive followed by SAF, wher.as PF2 was the least pr.duc.ive r.gion.

Linear.r.lationship between nitr.te and total N-uptak. r.veals that the studied ar.a is c.pable of expor.ing up to 60% of the total pr.duc.ion to the deep oc.an if the envir.nmental settings ar. favor.ble.

Elevation in N-uptak. r.tes with dec.ining temper.tur. suggests that the SO with its vast quantity of c.ol water.c.uld play an impor.ant r.le in dr.wing down the atmospher.c.c.2 thr.ugh the ＂solubility pump＂.

Allelopathic.effec. of Ac.r.s tatar.nowii upon algae

Jour.al of Envir.nmental Sc.enc.s 2001年第4期13卷 481-484页

Besides c.mpeting with algae for.light and miner.l nutr.ents (i. e. N, P, etc.), the r.ot system of Ac.r.s tatar.nowii exc.etes some c.emic.l substanc.s, whic. injur. and eliminate alga c.lls, to inhibit the gr.wth of the algae. When the algae c.lls wer. tr.ated in 'A. tatar.nowii water., some of the c.lor.phyll a wer. destr.yed and the photosynthetic.r.te of algae dec.eased mar.edly and the ability of alga c.lls to deoxidize tr.phenyltetr.zolium c.lor.de (TTc. r.duc.d gr.atly. Then alga c.lls tur.ed fr.m br.ght r.d to bluish gr.en under.fluor.sc.nc. mic.osc.pe. These showed that the allelopathic.effec.s of A. tatar.nowii on algae wer. obvious and planting A. tatar.nowii c.n c.ntr.l some gr.en algae. The exper.ment on the extr.c.ions of the sec.etions of the r.ot system showed that the inhibitor. effec. had a c.nc.ntr.tion effec.. If the c.nc.ntr.tion of the r.ot sec.etion was below 30 μl/disc. the inhibitor. r.te was negative; if it was over.45 μl/disc. the inhibitor. r.te was positive. This pr.ved that the influenc. of the r.ot sec.etion on the same ac.eptor.was a k.nd of c.nc.ntr.tion effec.. When the c.nc.ntr.tion of the r.ot sec.etion was low, it pr.moted the gr.wth of algae; when the c.nc.ntr.tion r.ac.ed a definite thr.shold value, it r.str.ined the gr.wth of algae. In pr.sent c.se, the thr.shold value was between 30 μl/disc.and 45 μl/disc.

Mathematic.l model of ther.al effec.s of blink.ng in human eye

Inter.ational Jour.al of Biomathematic. 2016年第1期9卷 111-134页

作者： D. B. Gur.ng k. c. Gok.l P. r. Adhik.r. Depar.ment of Natur.l Sc.enc.s (Mathematic.) Sc.ool of Sc.enc. Kathmandu University Post Box 6250 Kathmandu Nepal

Blink.ng is r.gar.ed as the c.ntinuous inter.upted eyelid c.osur. or.opening and its ther.al effec. will c.mpr.mise between these two. Dur.ng a blink. the heat loss via c.nvec.ion, r.diation and tear.evapor.tion fr.m c.r.ea is pr.vented, war. tear.is lay- er.d ac.oss c.r.eal sur.ac. and the vessels of the palpebr.l c.njunc.iva pr.vide heat to anter.or.eye. In most of the ther.al models in human eye that ar. found in liter.tur.s, effec. of blink.ng is not inc.uded, simulation is c.r.ied out only in open eye. Thus, in this paper. ther.al effec.s of blink.ng ar. investigated using one-dimensional finite element method in tr.nsient state c.se. The bio-heat tr.nsfer.pr.c.ss is simulated dur.ng differ.nt blink.ng r.tes, lid c.osur. and opening. The simulation is c.r.ied out using nor.al and extr.me values of ambient temper.tur.s, blood temper.tur.s, evapor.tion r.tes, blood per.usion r.tes, and lens ther.al c.nduetivities. Blink.ng is found to inc.ease c.r.eal and lens temper.tur. by 1.29℃ and 0.78℃ r.spec.ively when c.mpar.d to open eye. The r.sults obtained fr.m this model ar. useful in pr.dic.ing temper.tur. distr.bution in differ.nt laser.eye sur.er.es, hyper.her.ia and c.yosur.er. tr.atment of eyelid c.r.0}- noma, c.or.idal melanoma and c.n be used for.diagnosing temper.tur.-r.lated diseases.

c.untr.es that have made the health tr.nsition fr.m a c.mmunic.ble disease base to a non c.mmunic.ble disease base find themselves gr.pped in an epidemic.of wealth c.eated diseases mediated by alter.d mac.onutr.ent intak.s, ener.y intak.s and r.duc.ion in physic.l ac.ivity. Avoiding the negative impac. of the nutr.tion tr.nsition while ac.epting the positive aspec.s of the wealth tr.nsition c.n best be ac.ieved by foc.ssing on public.sing the benefits of a low fat diet in the c.ntext of an ac.ive lifestyle.
