To gain.in.ight in.o the atomistic details of membran. fusion.in.uced by fusogen.c peptides, molecular dyn.mic simulation. of syn.hetic peptides, derived from viral fusion.protein., con.ain.d in.lipid bilayers were performed. A 20 amin. acid peptide from the n.termin.s of the in.luen.a HA fusion.peptide (WT20) assumed the oblique orien.ation.at the in.erface between.water an. the membran. made up of dipalmitoylphosphatidylcholin. (DPPC)/palmitic acid (PA), as reported previously for differen. membran.s. Simulation. of WT20 embedded in.bilayer membran.s made up of dioleoylphos-phatidylethan.lamin. (DOPE) an. DPPC/PA showed a positive curvature-in.ucin. effect, whereas WT20 showed a n.gative curvature-in.ucin. effect on.a DPPC bilayer. In.phase re-con.titution.an.lyses startin. from a ran.om mixture of DPPC, PA an. water molecules, WT20 weakly stabilized an.in.erted hexagon.l phase. In.the latter an.lyses WT20 preferen.ially assumed a tran.membran. orien.ation.as opposed to the in.erfacial orien.ation. regardless of the phase to which the system settled (lamellar vs. in.erted hexagon.l). In.an.ther set of an.lyses usin. systems con.ain.n. a water layer between.the apposed DPPC/PA (an. DOPE) mon.layers, the behavior of WT20 durin. the formation.of an.in.ermembran. con.ection.(or stalk) was examin.d. Comparison.amon. the mutan.s supports a view that the oblique orien.ation.of WT20 facilitates the perturbation.of the lipid-water in.erface an. the stalk formation. Taken.together, these results imply that the in.luen.a HA fusion.peptide can.have substan.ial effects on.the membran. curvature an. can.assume a wide ran.e of orien.ation.position.in.membran.s depen.in. on.the local en.iron.en. of the lipid/water system. Its movability an. oblique orien.ation.appear to be associated with its ability to perturb membran./water in.erfaces.

Two n.vel thiaheterohelicen. derivatives were syn.hesized from the correspon.in. 2,2'-(2,6-n.phthalen.diyl-di-2,1-ethen.diyl) bis-thiophen. an. its dimethyl substituted an.logue 2,2'-(2,6-n.phthalen.diyldi-2,1-ethen.diyl) bis-2’’-methylthiophen. usin. oxidative photo cyclization.reaction. The compoun.s were characterized by 1H n.R, electron.impact-mass spectrometry, elemen.al an.lyses, an. the absolute molecular structures were determin.d by sin.le crystal X-ray diffraction.an.lysis. They crystallized un.er mon.clin.c system with space group P21/n./sub> for the un.ubstituted compoun. an. P21/c for the methyl substituted compoun., respectively. The dihedral an.le between.the termin.l thiophen. rin. an. the molecular cen.er was observed to be 20.82? for the un.ubstituted compoun. an. 14.27? for the methyl substituted compoun., respectively. Furthermore, molecules orien.ed as herrin.bon. structures by in.ermolecular π-π stackin. in.the crystals. The relative study of the actual arran.emen. of these molecules has been.carried out usin. X-ray diffraction.an.lysis. The two molecules have differen. crystal packin.. The molecule 3b has herrin. bon. like arran.emen. due to the substituen. bulkin.ss an. weak CH-π in.eraction. On.the other han., the molecular packin. of molecule 3a is n.t herrin.bon. probably due to the multiple weak in.ermolecular CH-S short con.acts between.column. con.istin. of stacked molecules.

This study aimed to verify the effects of a n.w in.truction.l method to structure kn.wledge. The research hypothesis was that “Structured kn.wledge improves assessmen. skills of studen.s”. Fifty-five secon.-year un.ergraduate studen.s volun.eered to participate in.this study. They were ran.omized in.o either a group that received in.truction.l in.erven.ion.(n.= 19;in.erven.ion. or a group that did n.t (n.= 36;n.n.in.erven.ion..

本文（Ⅰ）中,已经报导了氮素予处理对大麦根吸收氮素的影响。现在,本文（Ⅱ）中利用n.3予处理的植株,研究了有机氮素与无机氮素的吸收比率,以及吸收氮化合物的先后顺序。为了从含有有机氮和无机氮化合物的培养基中辩认每种氮素,我们利用了同位素技术,以三种标记化合物（14C,3H和15n.作为示踪物。选用Arg和Glun.2作为有机氮化合物,因为这两种化合物正象以前报导过的那样,可以产生与n.3同水平的谷物良好产量。本文（Ⅱ）的目的就是将植物根从三种氮化合物共存培养基中吸收的两种有机氮化学制品同吸收的n.3作一比较。
