The Qaidam Basin is one of the most sensitive areas to climate change in China, owing to its unique geographical position and ecological condition. In this study, 32 surface-soil pollen samples were collected to reveal the relationship between modern pollen assemblages, vegetation and precipitation in the eastern region of the Qaidam Basin. The results show that Chenopodiaceae (3.887%, average 48%
Three sets of research criteria are available for diagnosis of Alzheimer's disease in subjects with mild cognitive impairment: the International Working Group-1, International Working Group-2, and National Institute of Aging-Alzheimer Association criteria. We compared the prevalence and prognosis of Alzheimer's disease at the mild cognitive impairment stage according to these criteria. Subjects wi
Background In many European countries, medicines promotion is governed by voluntary codes of practice administered by the pharmaceutical industry under its own system of self-regulation. Involvement of industry organizations in policing promotion has been proposed to deter illicit conduct, but few detailed studies on self-regulation have been carried out to date. The objective of this study was to
The Half Heuslers are currently an attractive family of compounds for high temperature thermoelectrics research, and recently, there has been renewed interest since some of these compounds are proposed to be topological insulators. NiTiSn belongs to the family of 18 valence electron Half Heuslers that are predicted to be semiconducting, despite being composed entirely of metallic elements. The gro
Organic acids, central to terrestrial carbon metabolism and atmospheric photochemistry, are ubiquitous in the troposphere in the gas, particle, and aqueous phases. As the dominant organic acids in the atmosphere, formic acid (FA, HCOOH) and acetic acid (AA, CH3COOH) control precipitation acidity in remote regions and may represent a critical link between the terrestrial carbon and water cycles by
Background: There is a paucity of instruments designed to evaluate the multiple dimensions of the workplace as an educational environment for undergraduate medical students. Aim: The aim was to develop and psychometrically evaluate an instrument to measure how undergraduate medical students perceive the clinical workplace environment, based on workplace learning theories and empirical findings. Me
Objective: Autism spectrum disorders are considered to be among the most heritable mental disorders, a notion based on surprisingly sparse data from small clinical studies. Population-based studies of the heritability of other neuro-psychiatric disorders and comorbidities among them have also been sparse. The authors sought to address both of these issues. Method: Parents of all Swedish 9- and 12-
This article seeks to outline a conceptual landscape that can assist us to better grasp how urban communities torn and traumatised by violent conflicts remain divided in peace and resistant to liberal peacebuilding efforts. It suggests that peacebuilding needs to be urbanised to better address and mitigate tensions and ethnocratic spatial practices in divided cities. The urban is suggested as a pr
Reproductive factors influence the risk of developing epithelial ovarian cancer (EOC), but little is known about their association with survival. We tested whether prediagnostic reproductive factors influenced EOC-specific survival among 1025 invasive EOC cases identified in the European Prospective Investigation into Cancer and Nutrition (EPIC) study, which included 521 330 total participants (ap
It has been unclear whether ischemic stroke induces neurogenesis or neuronal DNA rearrangements in the human neocortex. Using immunohistochemistry; transcriptome, genome and ploidy analyses; and determination of nuclear bomb test-derived (14)C concentration in neuronal DNA, we found neither to be the case. A large proportion of cortical neurons displayed DNA fragmentation and DNA repair a short ti
Since the non-military dissolution of the political union with Norway in 1905, the myth of Sweden as a peace-power state, often with religious motivations, has been actual, and continuosly re-activated. In his ecumenical-political actions, Archbishop Nathan Söderblom was one of the most outstanding actors. Later, the political martyrdom of Count Folke Bernadotte, Dag Hammarskjöld, Raoul Wallenberg
In recent years questions concerning whether and how networks between small and medium-sized enterprises (SMEs) can serve as platforms for inter-organizational collective learning have attracted interest. In the present paper it is argued that two prerequisites for this are recognition of common needs and goals that contribute to the construction of a collective identity and the presence of promot
Background: Current information on the role of internists in the European countries is scarce. This report describes the results of a survey of the practice of internists in Europe. Methods: Two online questionnaire-based surveys were carried out by the European Board of Internal Medicine, one on the practice of internists and the other on postgraduate training in internal medicine. The national i
Inhibitors for galectin-1 and -3 were synthesized from thiodigalactoside and lactosamine by derivatization of the galactose C3. Introduction of 4-phenyl-1H-1,2,3-triazol-1-yl substituents at the thiodigalactoside C3 by CuAAC, targeting arginine-arene interactions, increased the affinity to 13 nM but yielded little selectivity. The builder 4-(4-phenoxypheny1)-1H-1,2,3-triazol-1-yl substituent, howe
We have developed the novel Aerosol Dynamics, gas- and particle-phase chemistry model for laboratory CHAMber studies (ADCHAM). The model combines the detailed gas-phase Master Chemical Mechanism version 3.2 (MCMv3.2), an aerosol dynamics and particle-phase chemistry module (which considers acid-catalysed oligomerization, heterogeneous oxidation reactions in the particle phase and non-ideal interac
During Botswana's four decades of high levels of growth the agricultural sector has lagged behind, with smallholder productivity being especially poor. This paper applies an equity perspective: its main claim is that one important explanation for the current lack of agricultural development is the unequal distribution of agricultural resources. It takes into account both the national institutional
Exome sequencing studies in complex diseases are challenged by the allelic heterogeneity, large number and modest effect sizes of associated variants on disease risk and the presence of large numbers of neutral variants, even in phenotypically relevant genes. Isolated populations with recent bottlenecks offer advantages for studying rare variants in complex diseases as they have deleterious varian
The developing high-resolution chronostratigraphy of the Cambrian provides an updated age model for various geologic and biotic events that occurred during this critical period of Earth history. Broad, time-specific patterns of lithofacies, such as organic-rich deposits, and biofacies appear to be consistent across all Cambrian paleocontinents. Records of important evolutionary events including fi
