Africa is the cradle of all human beings, and although it has been the focus of a number of genetic studies, there are many questions that remain unresolved. We have performed one of the largest and most comprehensive meta-analyses of mitochondrial DnA （mtDnA） lineages carried out in the African continent to date. We generated high-throughput mtDnA single nucleotide polymorphism （SnP） data （230 SnPs） from 2024 Africans, where more than 500 of them were additionally genotyped for the control region. These data were analyzed together with over 12,700 control region profiles collected from the literature, representing more than 300 population samples from Africa. Insights into the African homeland of humans are discussed. Phylogeographic patterns for the African continent are shown at a high phylogeographic resolution as well as at the population and regional levels. The deepest branch of the mtDnA tree, haplogroup L0, shows the highest sub-haplogroup diversity in Southeast and East Africa, suggesting this region as the homeland for modem humans. Several demographic estimates point to the coast as a facilitator of human migration in Africa, but the data indicate complex patterns, perhaps mirroring the effect of recent continental-scaled demographic events in re-shaping African mtDnA variability.

A series of new complex salts of the type [R]2[MC14] where R =[Ph-C=n-n-Ph n=n-Ph],M = Mn2＋, Co2＋, ni2＋, Cu2＋ and Zn2＋ wereprepared and characterized by elemental analysis, molar conductance, IR and UVnis is spectral studies and magnetic *** crystal structure of[Ph-C=n-n-Ph n=n-Ph]2[CuCl4] was determined by single crystal X-ray crystallography. The structure consisted of anion part and a 2,3,5-（triphenyl） tetrazolium cation as counter ions. The copper complex has a distorted tetrahedral geometry, the CI（1）-Cu-CI（2） [124.33 （2°）] and Cl（3）-Cu-Cl（4） [131.03 （2°）] angles are significantly larger than the ideal tetrahedral. The [CuCI4] anion and its counter ions are connected through a hydrogen bonds between C1 of the dianion and hetero aromatic rings by Cl-π, π-π and C-H … π, interactions.

Effects of Household Storage and Plumbing Systems on the Levels of Trace Elements in Desalinated Drinking Water in Kuwait

引用

Journal of Environmental Protection 2012年第11期3卷 1470-1484页

作者： Humood F. Al-Mudhaf nabeel M. Al-Khulaifi Mohammad n. Al-Hayan Abdel-Sattar I. Abu-Shady Chemical Engineering Technology Department College of Technological Studies Public Authority for Applied Education and Training Adailiyah Kuwait Environmental Health Department College of Health Sciences Public Authority for Applied Education and Training Adailiyah Kuwait

Household desalinated drinking water samples collected from outdoor points and from indoor consumption points at 99 locations representing more than 95% of the residential areas in Kuwait were analyzed for 25 trace elements and water quality parameters. Only Al, Cr, Co, Cu, Fe, Pb, ni, and Zn were found to be over-represented at the consumption point compared with the outdoor point, with wide variations among the sampling locations and elements. The highest increases were observed for Fe (135%) and Zn (123%), followed by Pb (69%), Co (58%), Cu (42%), Cr (31%), and Al (30%), and the lowest increase was observed for ni (19%). In most cases, the increases in Cu, Fe, and Zn were inversely proportional to the conductivity and directly proportional to the Cl– concentration. In the outdoor samples, only Fe exceeded the US-EPA guideline (in 3% of the outdoor samples taken), whereas Fe, Pb, and ni exceeded the US-EPA and WHO guidelines in 8.5%, 0.3%, and 1% of the indoor consumption point samples, respectively. Thus, leaching from household utilities may cause health concerns for consumers of drinking water in Kuwait. The increases in Fe were the highest in the summer (240%), and in this regard, Fe exhibited the greatest difference between summer and winter (the increase was 139% higher in the summer). The results of the present study may be useful for water production authorities and consumers in Kuwait and suggest the use of alternative new pipes with more resistant internal coatings and connecting techniques.

Organ at Risk Doses during High Dose Rate Intracavitary Brachytherapy for Cervical Cancer: A Dosimetric Study

引用

International Journal of Medical Physics, Clinical Engineering and Radiation Oncology 2018年第4期7卷 472-478页

作者： n. V. Vinin Joneetha Jones V. T. Ajas Geetha Muttath C. A. Suja E. K. nabeel Yahiya P. n. Shoaib nawaz Arun P. narendran P. Shimjith Department of Radiation Oncology Malabar Cancer Centre Thalassery Kerala India

Background: Treatment of Cervical cancer includes a combination of external beam radiotherapy (EBRT) with intracavitary brachytherapy (ICBT). ICBT helps to boost radiation dose to primary disease. Organs like rectum, bladder, sigmoid and small bowel lie close to the cervix region and these organs receive dose from EBRT as well as ICBT and we want to know the dose to these organ at risk (OAR). Materials & Methods: Dosimetric details of 174 ICBT applications done in 58 patients were retrospectively analysed. All patients received EBRT dose of 50.4 Gy in 28 fractions. All patients had ICBT, three sessions with 7 Gy prescribed to point A. Dosimetric data including dose to right and left point A and dose to OARs were recorded from Oncentra Planning System. Results: Mean dose to point A on right side was 6.89 Gy and left side was 6.91 Gy. Mean D2cc dose to rectum, bladder, sigmoid and small bowel was 3.5 Gy, 5.25 Gy, 4.75 Gy and 4.2 Gy respectively. Mean EQD2 dose combining EBRT and ICBT in point A was 78.7 Gy on right side and 79 Gy on left side. Mean EQD2 doses to D2cc of rectum, bladder, sigmoid and small bowel was 62 Gy, 74.4 Gy, 70.5 Gy and 66.5 Gy respectively. Conclusion: From the results of this dosimetric study it is evident that OARs like rectum, sigmoid, bladder & bowel are receiving only acceptable doses of radiation using point A prescribed CT based ICBT planning. Hence with regards to OAR doses, CT based ICBT planning with dose prescribed to point A is a feasible option.
