Mantle Sources of Recent Anatolian Intraplate Magmatism: A Regional Plume or Local Tectonic Origin?

Tectonics 2018 Dec 15;37(12):4535-4566. Epub 2018 Dec 15.

Department of Earth Sciences Utrecht University Utrecht The Netherlands.

We present an extensive study of rehomogenized olivine-hosted melt inclusions, olivine phenocrysts, and chromian spinel inclusions to explore the link between geodynamic conditions and the origin and composition of Pliocene-Quaternary intraplate magmatism in Anatolia at Kula, Ceyhan-Osmaniye, and Karacadağ. Exceptional compositional variability of these products reveals early and incomplete mixing of distinct parental melts in each volcanic center, reflecting asthenospheric and lithospheric mantle sources. The studied primitive magmas consist of (1) two variably enriched ocean island basalt (OIB)-type melts in Kula; (2) both OIB-type and plume mid-ocean ridge basalt (P-MORB)-like melts beneath Toprakkale and Üçtepeler (Ceyhan-Osmaniye); and (3) two variably enriched OIB-type melts beneath Karacadağ.

Joint attention skills in wild Arabian babblers ( Turdoides squamiceps): a consequence of cooperative breeding?

Proc Biol Sci 2019 Apr;286(1900):20190147

4 Institute of Cognitive Science, Comparative BioCognition , University of Osnabrück , Osnabruck , Germany.

Human cooperation strongly relies on the ability of interlocutors to coordinate each other's attentional state: joint attention. One predominant hypothesis postulates that this hallmark of the unique cognitive system of humans evolved due to the combination of an ape-like cognitive system and the prosocial motives that facilitate cooperative breeding. Here, we tested this hypothesis by investigating communicative interactions of a cooperatively breeding bird species, the Arabian babbler ( Turdoides squamiceps). Read More

Process and mechanism of nitrogen loss in the ocean oxygen minimum zone.

Ying Yong Sheng Tai Xue Bao 2019 Mar;30(3):1047-1056

Key Laboratory of Marine Ecology and Environmental Science, Institute of Oceanology, Chinese Academy of Sciences, Qingdao 266071, Shandong, China.

There is a big imbalance between the input and output of oceanic nitrogen in global ocean nitrogen cycles, because a part of the fixed nitrogen is reduced to N or NO and then lost from the ocean. Oxygen minimum zone (OMZ) is the most important area for nitrogen loss, which could lose fixed nitrogen up to 40 to 450 Tg·a through the denitrification and anammox. A summary of the two main roles of nitrogen loss in the different OMZ sea areas reveals that heterotrophic denitrification dominates in eastern tropical Pacific, Arabian Sea, and marine sediments.

HLA class I allele lineages and haplotype frequencies in Arabs of the United Arab Emirates.

Int J Immunogenet 2019 Mar 20. Epub 2019 Mar 20.

School of Psychiatry and Clinical Neurosciences, The University of Western Australia, Crawley, Western Australia, Australia.

The high degree of polymorphism of the HLA system provides suitable genetic markers to study the diversity and migration of different world populations and is beneficial for forensic identification, anthropology, transplantation and disease associations. Although the United Arab Emirates (UAE) population of about nine million people is heterogeneous, information is limited for the HLA class I allele and haplotype frequencies of the Bedouin ethnic group. We performed low-resolution PCR-SSP genotyping of three HLA class I loci at HLA-A, -B and -C for 95 unrelated healthy Bedouins from the cities of Al Ain and Abu Dhabi in the UAE. Read More

Study of Primordial 226Ra, 228Ra, and 40K Concentrations in Dietary Palm Dates and Concomitant Radiological Risk.

Health Phys 2019 Mar 19. Epub 2019 Mar 19.

Centre for Biomedical Physics, School of Healthcare and Medical Sciences, Sunway University, Selangor, Malaysia.

The presence of natural radionuclides in the food chain point to a need to assess concentration levels and concomitant radiological risk. Highly popular and forming a staple part of the diet in North Africa, the Arabian Peninsula, and West Asia, palm dates growing naturally there have even greater marketability than simple satisfaction of domestic demand, the palm dates representing a valuable export item. Accurate knowledge of the levels of natural radioactivity in the fruit is thus of importance. Read More

Episiotomy in modern clinical practice: friend or foe?

Int Urogynecol J 2019 Mar 13. Epub 2019 Mar 13.

Department of Obstetrics and Gynecology, College of Medicine and Medical Sciences, Arabian Gulf University, Manama, Bahrain.

The Cochrane library first published a meta-analysis in 2000 on the role of the episiotomy in modern clinical practice, which concluded that only a policy of selective episiotomy is acceptable with evidence-based improvement in maternal health compared with routine episiotomy. Many years later, however, the new version of the Cochrane meta-analysis changed the previous recommendations in that the selective use of episiotomy could not be considered beneficial in all cases. A selective policy is associated with a statistically significant reduction in severe perineal and/or vaginal trauma, whereas routine episiotomy seems to protect against these complications only after instrumental deliveries.
