1AZF microdeletions and partial deletions of AZFc region on the Y chromosome in Moroccan men显示文摘瞄准:第一次评估 Y 染色体的频率,并且讨论 AZF 删除的临床的意义微删除和在摩洛哥的人的 AZFc 区域的部分删除的出现。方法:我们屏蔽了 Y 染色体微删除和不肥沃的人的一个连续的组的 AZFc 区域的部分删除(n = 149 ) 并且控制(100 个肥沃的人, 76 个 normospermic 人) 。AZFa, AZFb, AZFc 和 AZFc 区域的部分删除被聚合酶链反应(PCR ) 根据确定的协议分析。结果:在为微删除屏蔽的 127 个不肥沃的人之中,四个题目被发现有微删除:二 AZFc 删除和二 AZFb+AZFc 删除。所有删除仅仅在 azoospermic 题目被发现(4/48, 8.33%) 。全面 AZFc 删除频率是低的(4/127, 3.15%) 。AZF 微删除没在 oligoasthenoteratozoospermia (燕麦) 或控制被观察。AZFc (gr/gr ) 的部分删除总共部分 AZFc 删除(gr/gr ) 在控制组被发现的 149 个不肥沃的人(4.70%) 中的 7 个和 7 的被观察(7/176, 3.98%) 。另外,二 b2/b3 删除在二个 azoospermic 题目被识别(2/149, 1.34%) 然而并非在控制组。结论:我们的结果建议 Y 染色体 AZF 微删除的频率与严重 spermatogenic 失败在个人被提高并且 gr/gr 删除没与 spermatogenic 失败被联系。Laila Imken Brahim El Houate Abdelaziz Chafik Halima Nahili Redouane Boulouiz Omar Abidi Elbakkay Chadli Noureddine Louanjli Abdelouhab Elfath Mohammed Hassar Ken McElreavey Abdelhamid Barakat Hassan Rouba 2007Asian Journal of Andrology2007,9,5:22
2Layered double hydroxide(LDH)-based materials:A mini-review on strategies to improve the performance for photocatalytic water splitting显示文摘The high energy demand we currently face in society and the subsequent large consumption of fossil fuels cause its depletion and increase the pollution levels.The quest for the production of clean energy from renewable and sustainable sources remains open.The conversion of solar energy into hydrogen via the water-splitting process,assisted by pho tores pons ive semiconductor catalysts,is one of the most promising technologies.Significant progress has been made on water splitting in the past few years and a variety of photocatalysts active not only under ultra-violet(UV) light but especially with the visible part of the electromagnetic spectrum have been developed.Layered double hydroxides(LDH)-based materials have emerged as a promising class of nanomaterials for solar energy applications owing to their unique layered structure,compositional flexibility,tunable bandgaps,ease of synthesis and low manufacturing costs.This review covers the most recent research dedicated to LDH materials for photocatalytic water-splitting applications and encompasses a range of synthetic strategies and post-modifications used to enhance their performance.Moreover,we provide a thorough discussion of the experimental conditions crucial to obtaining improved photoactivity and highlight the impact of some specific parameters,namely,catalysts loading,cocatalysts,sacrificial agents,and irradiation sources.This review provides the necessary tools to select the election technique for adequately enhancing the photoactivity of LDH and modified LDH-based materials and concludes with a critical summary that outlines further research directions.Hanane Boumeriame Eliana S.Da Silva Alexey S.Cherevan Tarik Chafik Joaquim L.Faria Dominik Eder 2022Journal of Energy Chemistry2022,31,1:5
