We have carried out zircon U-Pb SHRIMP dating and Hf isotope determinations on a biotite paraschist and on a tonalitic orthogneiss of the Yaminué Complex, and re-evaluate this complex in the broader context of the tectonic evolution of the Patagonia composite terrane. In the metasedimentary unit （msuYC）, the youngest detrital zircon dated at 318 ± 5 Ma （Mississippian/Pennsylvanian boundary） indicates a Pennsylvanian （or younger） depositional age. The three main age populations peak at 474, 454 and 374 Ma. Preliminary Hf isotope data for two detrital zircons （447 and 655 Ma） yielded ε（Hf） values of -0.32 and 0.48, indicating that their primary sources contained small amounts of recycled crustal components （of Calymmian age; TDM 1.56 Ga）. Zircons from the orthogneiss （miuYC; intrusive into msuYC） show a crystallization age of 261.3 - 2.7 Ma （Capitanian; late middle Permian） which is broadly coeval with deformation, and Neoarchean-Paleoproterozoic inheritance. Meaningful core-rim relationship between Neoarchean zircon cores and late Permian rims is well defined, indicating the occurrence of Archean crust in this sector of Patagonia. Hf TDM of Permian zircons is mainly Meso-Paleoarchean （2.97-3.35 Ga）, with highly negative e（Hf） values （ca, -33）. Hf TDM of inherited Neoarchean zircon cores is also Meso-Paleoarchean （3.14-3.45 Ga） but more juvenile （ε（Hf） = -0.3）. Hf isotopes reinforce the presence of unexposed ancient crust in this area. Combining geological and isotope data, as well as geophysical models, we identify the Yaminué Complex within the La Esperanza-Yaminué crustal block flanked by two other, distinct crustal blocks： the Eastern block which forms part of the Patagonia terrane sensu stricto, located in the eastern Patagonian region, and the Western block forming part of the Southern Patagonia terrane. Their origins and timing of amalgamation to form the Patagonia composite terrane are also discussed.

SHRIMP single zircon U-Pb dating of the Kongling high-grade metamorphic terrain: Evidence for >3.2 Ga old continental crust in the Yangtze craton

作者：高山凌文黎 QIU Yumin neal j.mcnaughton David I.Groves Department of Geology Northwest University Xi'an 710069 China Faculty of Earth Sciences China University of Geosciences Wuhan 430074 China

Single zircons from two trondhjemitic gneisses and two clastic metasedimentary rocks without Eu anomaly of the Kongling high-grade metamorphic terrain are dated by the in situ SHRIMP U-Pb method. The results show that the trondhjemitic magma emplaced at 2947-2903 Ma. Concordant age of as old as 3.3 Ga is present in the detrital zircons from the clastic metasedimentary rocks. Together with the depleted mantle Nd model age (TDM =3.2-3.3 Ga) of the clastic metasedimentary rocks, this documents the presence of Paleoarchean continental crust in the Yangtze craton.

Geochronology and Significance of Granites Associated with Gold Deposits in the jidong Area, China

引用

Acta Geologica Sinica(English Edition) 2000年第2期74卷 306-310页

作者： neal mcnaughton David GROVES Department of Geology University of West Australia AustraliaDepartment of Geology University of West Australia Australia

The jidong area is located on the north margin of the North China craton. It is a nucleus composed of the oldest rocks in China. Precambrian metarnorphic rocks with various Phanerozoic granitoids invaded are widespread. Gold deposits here have close spatial relations to granitoids. Some deposits occur within them and others in the outer zone of the contact belt of the intrusion, extending thousands of metres. There have been controversial views in regard to the relations of the deposits to the intrusions although traditional techniques have been used to date the intrusions. In order to solve such a problem, the SHRIMP technique was adopted to date the U-Pb ages of zircon collected from the Yuerya intrusion which hosts the large-sized Yuerya Au deposit and Qingshankou intrusion 2 km away from the jinchangyu (larger-sized) Au deposit. Analysis shows that the ages of 175±1 Ma and 174±3 Ma for Yuerya intrusion and the age of 199±2 Ma for Qingshankou granite indicate the Early Yanshanian stage of the Mesozoic. The Yuerya intrusion also contains inherited zircon aged at about 2500 Ma, indicating that part of its source materials are Archaean metamorphic rocks. In addition to the SHRIMP data of this study, a great deal of data related to the alteration of Au deposits indicate the formation of the deposits at the Yanshanian stage of the Mesozoic, so the ore formation of Au deposits is inferred to relate to granitic intrusion.

大桦背花岗岩体位于内蒙古乌拉山地区,东距哈达门沟大型钾长石—石英金矿床约5km。前人对该岩体曾做过不少同位素年代学研究,所得结果相差较大,但是多数研究者认为大桦背岩体与区内金矿化具有成因联系。本文采用先进的高灵敏、高分辨率的离子探针(SHRIMP)对大桦背岩体进行了锆石U-Ph定点定年研究。结果表明,大桦背岩体的形成年龄为353±7Ma,应为海西旋回早期产物。此年龄比已得到的乌拉山金矿区成矿年龄大至少70Ma,因而推测大桦背岩体与金矿化之间不存在直接的成因联系。

Leadless pacemakers： a contemporary review

journal of Geriatric Cardiology 2018年第4期15卷 249-253页

作者： neal Bhatia Mikhael El-Chami Department of Medicine Division of Cardiology Section of Electrophysiology Emory University School of Medicine Atlanta USA

1 Introduction Over one million cardiac pacemakers are implanted every year worldwide,[11 of which approximately 200,000 are implanted in the United States alone.121 Combined with an aging population and increasing pacing indications, these numbers are expected to grow. Since the first pacemaker implantation in 1950s, cardiac pacemaker technology has rapidly advanced. Reduction in generator size, increased battery longevity, quality of pacemaker leads, algorithmic and rate responsive programming-all have revolutionized and transformed the implantation and management of transvenous cardiac pacemaker （TV-PPM）.

Phylogenetic and sequence analyses of insect transferrins suggest that only transferrin 1 has a role in iron homeostasis

Iron is essential to life,but surprisingly little is known about how iron is managed in nonvertebrate *** mammals,the well-characterized transferrins bind iron and are involved in iron transport or immunity,whereas other members of the transferrin family do not have a role in iron *** insects,the functions of transferrins are still poorly *** goals of this project were to identify the transferrin genes in a diverse set of insect species,resolve the evolutionary relationships among these genes,and predict which of the transferrins are likely to have a role in iron *** phylogenetic analysis of transferrins from 16 orders of insects and two orders of noninsect hexapods demonstrated that there are four orthologous groups of insect *** analysis suggests that transferrin 2 arose prior to the origin of insects,and transferrins/,i,and 4 arose early in insect *** sequence analysis of each of the insect transferrins was used to predict signal peptides,carboxyl-terminal transmembrane regions,GPI-anchors,and iron *** on this analysis,we suggest that transferrins 2,and 4 are unlikely to play a major role in iron *** contrast,the transferrin 1 orthologs are predicted to be secreted,soluble,iron-binding *** conclude that transferrin 1 orthologs are the most likely to play an important role in iron ***,it appears that the louse,aphid,and thrips lineages have lost the transferrin 1 gene and,thus,have evolved to manage iron without transferrins.

Prevention of erectile dysfunction after radiotherapy for prostate cancer

引用

Asian journal of Andrology 2014年第6期16卷 805-806页

作者： Izak Faiena neal Patel Allen D Seftel Division of Urology Rutgers Robert Wood JohnsonMedical School N J USA 2Division of Urology Cooper Medical School of Rowan University CamdenN J USA.

With increasing scrutiny of prostate cancer （PCa） diagnosis and treatment, much attention has been given to the morbidity caused by radical prostatectomy （RP） and/or radiotherapy （RT）. One of the most common side-effects of either treatment is erectile dysfunction （ED）.1 Approximately, 40% of patients will experience ED after RT for PCa. The post-RT ED causes significant patient dissatisfaction with cancer treatment as well as decrease in patient and partner psychosocial function,z To address this issue in patients undergoing RT, Pisansky et al.3 conducted a prospective, randomized, double-blinded, placebo-controlled trial to assess the efficacy of a phosphodiesterase enzyme-5 inhibitor （PDE5i）, tadalafil, as a preventive measure for patients undergoing RT for PCa and found no difference in erectile function between the control and treatment groups.
