有一部分神经病理性疼痛是由脊髓后角的中枢神经敏化引起的。但其敏化的形成机制仍不清楚。有证据表明,脊髓血管网络完整性的破坏可能是神经病理性疼痛的致病因素。该研究验证了脊髓后角处的血流量和血管分布减少会导致神经病理性疼痛的发作。通过使用导致脊髓后角内皮退化的啮齿动物模型(Ⅰ型糖尿病和可诱导的内皮特异性脊髓后角血管内皮生长因子受体2敲除小鼠),发现脊髓血管病变导致伤害性行为超敏反应,同时这也导致神经元缺氧增加,表现为缺氧诱导因子1α、葡萄糖转运脊髓后角蛋白3和碳酸酐酶7等缺氧标志物表达增加。此外,通过鞘内递送二甲基草酰甘氨酸诱导缺氧导致脊髓后角激活神经元以及机械和热超敏反应,表明由血管减少引起的缺氧信号会导致超敏反应和疼痛增加。通过腹膜内注射乙酰唑胺抑制碳酸酐酶活性,抑制缺氧引起的疼痛行为表明在糖尿病中发生的脊髓后角缺氧微环境的诱导以激活神经元并引起神经性疼痛是一个完整的过程。该研究推测通过改善脊髓微血管血流来逆转缺氧状态可以逆转或预防神经病理性疼痛。

In groundwater hydrol.gy,aquitard heterogeneity is often l.ss considered compared to aquifers,despite its significant impact on groundwater hydraul.cs and groundwater resources eval.ation.A semi-anal.tical.sol.tion is derived for pumping-induced wel. hydraul.cs and groundwater budget with consideration of vertical.heterogeneity in aquitard hydraul.c conductivity(K)and specific storage(S_(s)).The proposed new sol.tion is innovative in its partitioning of the aquitard into mul.ipl. homogeneous sub-l.yers to enabl. consideration of various forms of vertical.y heterogeneous K or S_(s).Two scenarios of anal.tical.investigations are expl.red:one is the presence of aquitard interl.yers with distinct K or S_(s) val.es,a common fiel.-scal. occurrence;another is an exponential.y depth-decaying aquitard S_(s),a regional.scal. phenomenon supported by statistical.*** investigations reveal.that a l.w-K interl.yer can significantl. increase aquifer drawdown and enhance aquifer/aquitard depl.tion;a high-S_(s) interl.yer can noticeabl. reduce aquifer drawdown and increase aquitard *** of l.w-K or high-S_(s) interl.yers al.o significantl. impact wel. hydraul.cs and groundwater *** the context of an exponential.y depth-decaying aquitard S_(s),a l.rger decay exponent can enhance aquifer *** using current model. with a vertical.y homogeneous aquitard,hal. the sum of the geometric and harmonic means of exponential.y depth-decaying aquitard S_(s) shoul. be used to cal.ul.te aquitard depl.tion and unconfined aquifer l.akage.

In the purpose to design novel.antitubercul.sis (anti-TB) drugs agents against Mycobacterium tubercul.sis (Mtb), we have buil. a mol.cul.r l.brary around 42 Hal.mane Diterpenoids isol.ted from natural.sources. Two Mtb enzymes drug targets (Mtb Mycothiol.S-transferase and Mtb Homoserine transacetyl.se) have been adopted. The pharmacol.gical.potential.was investigated through mol.cul.r docking, mol.cul.r dynamics simul.tion, density functional.theory (gas phase and water) and ADMET anal.sis. Our resul.s indicate that (2R,5R,6S)-1,2,3,4,5,6,7,8-octahydro-5-((E)-5-hydroxy-3-methyl.ent-3-enyl.-1,1,5,6-tetramethyl.aphtha-l.ne-2-ol.(compound 20) has displ.ys higher docking score with each of the sel.cted drug targets. In addition, this mol.cul. exhibits a satisfactory drug potential.activity and a good chemical.reactivity. Its improved kinetic stabil.ty in the Mtb Mycothiol.S-transferase enzyme refl.cts its suitabil.ty as a novel.inhibitor of Mtb growth. This mol.cul. has displ.yed a good absorption potential. Our resul.s al.o show that its passive passage of the intestinal.permeabil.ty barrier is more effective than that of first-l.ne treatments (ethambutol. isoniazid). In the same way, this anti-TB drugl.keness has shown to be abl. to cross the bl.od brain barrier.

This paper addresses the probl.m of Hopf-fl.p bifurcation of high dimensional.maps. Using the center manifol. theorem, we obtain a three dimensional.reduced map through the projection technique. The reduced map is further transformed into its normal.form whose coefficients are determined by that of the original.system. The dynamics of the map near the Hopf-fl.p bifurcation point is approximated by a so cal.ed “time-2τ^2 map” of a pl.nar autonomous differential.equation. It is shown that high dimensional.maps may resul. in cycl.s of period two, tori T^1 （Hopf invariant circl.s）, tori 2T^1 and tori 2T^2 depending both on how the critical.eigenval.es pass the unit circl. and on the signs of resonant terms＇ coefficients. A two-degree-of-freedom vibro-impact system is given as an exampl. to show how the procedure of this paper works. It reveal. that through Hopf-fl.p bifurcations, periodic motions may l.ad directl. to different types of motion, such as subharmonic motions, quasi-periodic motions, motions on high dimensional.tori and even to chaotic motions depending both on change in direction of the parameter vector and on the nonl.near terms of the first three orders.
