四氢生物蝶呤反应性苯丙氨酸羟化酶缺乏症

目的四氢生物蝶呤(BH4)可以使BH4缺乏症病人的血液苯丙氨酸水平正常化,但是对苯丙酮酸尿症(PKU)病人无效。最近在新生儿PKU筛查中发现了对BH4有反应的轻度PKU患者。本研究将探讨BH4和苯丙氨酸羟化酶(PAH)基因突变在对BH4有反应的轻度PKU和轻度高苯丙酸血症(HPA)患者中的作用。方法对经新生儿PKU筛查中发现的生物蝶呤代谢正常的轻度HPA患者,进行单次(10mg/kg)、4次、1周[20 mg/(kg·d)]的BH4口服负荷试验及长期BH4治疗,评估其对BH4口服负荷试验的反应性。结果在单剂量BH4口服负荷试验中,典型PKU患者的血苯丙氨酸水平没有降低。在单剂量BH4口服负荷试验中血苯丙氨酸水平下降超过20%的患者,在4次BH4口服负荷试验中下降亦超过20%。1周BH4负荷试验确认在单剂量和4次BH4负荷试验中表现出弱反应性的病人对BH4有反应。许多患轻度PKU和轻度HPA且有R241C基因位点的病人,都对BH4治疗有反应。在无BH4反应性的典型PKU病人中未发现R241C、P407S和A373T基因突变。结论1周BH4负荷试验用于诊断BH4反应性PAH缺乏症最为有效。等位基因R241C、P407S和A373T与轻度HPA和轻度PKU病人具有H4反应性有关。BH4治疗是针对轻度HPA和轻度PKU的一种新颖、有效的药物治疗,有望代替限制苯丙氨酸饮食的方法。

Journal of Physical Science and Application 2012年第7期2卷 233-239页

作者： Mohammed Nasim Hasan teruo Matsushita Miryala Muralidhar Department of Physics University of Chittagong Chittagong 4331 Bangladesh Department of Computer Science and Electronics Kyushu Institute of Technology lizuka 820-8502 Japan Senior Scientific Officer Superconductivity Research Laboratory Tokyo 105-0023 Japan

The pinning characteristics of a single crystal NdBa2Cu3Oy superconductor at low (40 K), intermediate (77.3 K) and high (88 K) temperatures were investigated. The experimental results of the critical current density Jc and the apparent pinning potential * 0 U which estimated from magnetic relaxation measurements are compared with the theoretical analysis based on the flux creep-flow model, taking the distribution of the flux pinning strength into account. The number of flux lines in the flux bundle (g2), the most probable value of pinning strength (Am), distribution width of pinning strength (σ2) and other pinning parameters such as m, γ, δ are determined so that a good fit is obtained between the experimental and theoretical results. The behavior of these parameters is discussed in correspondence to the pinning characteristics of low, intermediate and high temperatures. The observed results are approximately consistent with the theoretical predictions of Brandt et al. model of the order-disorder transition.

纤维素纤维用邻苯二甲酸酐和丁二酸酐进行化学处理。对抗MRSA,S·金霉素,K·肺炎细菌和T·mentagrophytes（抗细菌和抗真菌活性） ,及其它们的洗涤耐久性进行了评价。用丁二酐醍处理的样品抗S·金霉素和MRSA的抗菌活性优于邻苯二甲酸酐处理的样品。但对于抵抗K·肺炎细菌,这两种处理方法的结果无明显差别。经过10次重复循环洗涤后,抗菌活性略有降低, ,但耐洗涤性仍然保持在某个较高的水平,并且比商用抗菌除臭产品的性能优越。除此之外,改性的纤维具有预防革兰氏阳性细菌,革兰氏阴性细菌和真菌繁殖的作用。因此,化学改性的纤维素纤维表明其作为控制各种包括MRSA在内的医用传染性细菌的流行的助剂是可能的。
