1Relationships between native tree species and soil properties in the indigenous forest fragments of the Eastern Arc Mountains of the Taita Hills, Kenya显示文摘The relationship between soil properties and spatial distribution of native woody species was studied in three Taita Hills forest fragments which, although degraded, are ranked among 34 biodiversity hotspots of the world due to their high biodiversity of both plant and animal species. This relationship was assessed by using Spearman correlation and principal component analyses (PCA). The results of these analyses should be useful in instituting forest restoration programs that are crucial for the forests. Both the soil and vegetation studied were sampled from 17 subplots in the natural forest fragments of Ngangao (120 ha), Chawia (86 ha) and Mbololo (185 ha). The soil variables measured were: pH, texture, soil nutrients of C, N, Ca, P, K, Mg and Na. In total 36 native tree species from 13 families were identified from the three forest fragments. Ordination results show that axis 1 accounted for 35% and axis 2 for 25% of the total variation in species composition, indicating that the structure of vegetation is related to two major environmental gradients. The correlation analyses of species and soil properties showed that Na and clay particles were the most important determinants of species distribution; pH and soil variables such as C, N, Ca and P also played minor roles. Unexpectedly, some species (e.g. Psychotria petitii) showed positive relationships with Na attributed to possible substitution for K. Relationships with P were both positive (e.g. Craibia zimmermannii) and negative (e.g. Albizia gummifera) with some species, attributable to pH levels. An ANOVA for soil variables showed that there were differences in the Ca content in Mbololo (due to the parent material) and P in Ngangao where a special relationship was observed between some of the species. The presence of gaps accounted for the distribution of seedlings but not for the saplings, whose distribution responded more to factors similar to those to which mature trees respond. Soil-species relationships that were established may be utilized along with soil analyses when choosing native species for restoration.Loice Mildred Akinyi OMORO Raija LAIHO Michael STARR Petri K.E.PELLIKKA 2011Forestry Studies in China2011,13,3:2

9Targeting KRAS in pancreatic adenocarcinoma:Progress in demystifying the holy grail显示文摘Pancreatic cancer(PC)remains one of the most challenging diseases,with a very poor 5-year overall survival of around 11.5%.Kirsten rat sarcoma virus(KRAS)mutation is seen in 90%-95%of PC patients and plays an important role in cancer cell proliferation,differentiation,metabolism,and survival,making it an essential mutation for targeted therapy.Despite extensive efforts in studying this oncogene,there has been little success in finding a drug to target this pathway,labelling it for decades as“undruggable”.In this article we summarize some of the efforts made to target the KRAS pathway in PC,discuss the challenges,and shed light on promising clinical trials.Ahmed Elhariri Ahmed Alhaj Daniel Ahn Mohamad Bassam Sonbol Tanios Bekaii-Saab Christina Wu Michael Scott Rutenberg John Stauffer Jason Starr Umair Majeed Jeremy Jones Mitesh Borad Hani Babiker 2023World Journal of Clinical Oncology2023,14,8:0

12全髋和全膝关节成形术后功能问题和治疗答案显示文摘虽接受全髋或全膝关节成形术的多数患者通过常规的术后康复治疗可获得极佳的临床结果,而由各种原因导致的实际功能障碍仍占患者的15%~20%。这些患者对标准的物理治疗方式没有反应,而需要采用超强的处理方案.这些治疗方案包括侵害性和非侵害性治疗。本研究的目的是识别这些功能受限的患者,评估采用定制的治疗方案治疗的结果。我们规定那些不直接与假体相关的软组织问题。通过X线片或通过本文两名作者(M.M.&G.E.)的专门检查排除了由于力线不良或松动等所有有关假体的问题。我们列出了继全髋关节成形术和全膝关节成形术后的几个功能问题。这些问题涉及到肌无力、肌紧张、肢体不等长和神经问题。ANIL BHAVE MICHAEL MONT SCOTT TENNIS MICHELE NICKEY ROLAND STARR GRACIA ETIENNE 肖湘(译) 2006骨科动态2006,2,2:0
13森林土壤的酸沉降临界负荷:目前所用的方法适宜吗?显示文摘在欧洲范围内,临界负荷的概念已经被广泛接受,用之作为制订缓解策略的基础,仍减少或防止由于跨边界的酸性沉降物所引起的对森林生态系统的功能和活力的破坏。本文的目的是评述简单的稳态临界负荷模型的科学基础和假设。文中讨论了用碱阳离子/铝的比率作为化学数据的使用情况和有效性,并着重指出缺乏意义明确的生物学数据的情况。更为敏感的酸沉降指示物应为考虑地被层植物种、菌根真菌和土壤动物。特别应当指出的是,需要一种考虑了生态系统的时空变化、根际复杂性以及土壤生物之间的功能关系的更为动态的方法。Hans Lφkke Jesper Bak Ursula Falkengren-Grerup Roger D.Finlay Hannu Ilvesniemi Per Holm Nygaard Michael Starr 齐文同 1996人类环境杂志1996,25,8:0
