The red-haired pine bark beetle, Hylurgus ligniperda (Fabricius), is one of the most rapidly spreading invasive forest insects. Originally from Eurasia, it has subsequently been introduced to Oceania, North, and South America. Yet, the status of H. ligniperda in East Asia is ambiguous. Here, investigation and analysis were conducted on the beetle in China, South Korea, and Japan. New occurrences in China and South Korea were recorded by field surveys and the expansion of H. ligniperda spreading in East Asia was analyzed. The results show that H. ligniperda is likely an invasive species in East Asia, initially invading Japan, then South Korea. Now it has invaded and successfully colonized Shandong province, China. Furthermore, the species has spread rapidly and it is now widely distributed in South Korea and Japan.

The International Genetics of Ankylosing Spondylitis (IGAS) meeting was held in Houston, Texas, July 25, 2009. Sixteen investigators from Asia, Australia, Europe, and North and South America presented the status of their respective cohorts of patients with ankylosing spondylitis (AS). They also reviewed a proposal to examine their patients by single-nucleotide polymorphism (SNP) genotyping on an Illumina Infinium microarray SNP genotyping chip in a case-control cohort exceeding 12,000 samples. This chip will type 200,000 SNP selected from the most strongly associated variants identified in genome-wide association studies of inflammatory diseases, including inflammatory bowel disease, psoriasis, and ankylosing spondylitis.

Solifuges are an enigmatic and poorly studied group of arachnids. Commonly referred to as camel spiders or sun spiders, these animals are voracious predators of small animals and found in arid biomes of the Old World and the Americas. In this paper, we provide a catalogue for the solifuges (Arachnida: Solifugae) that are held at the Center of Natural History in Hamburg. The collections in Hamburg are predominantly historical and were accumulated by Karl Kraepelin between 1889 and 1914 with the help of other famous arachnologists such as Ferdinant Karsch and Eugène Simon. The re-study of these collections indicates that there are 38 type species and 65 type specimens from 10 families. We provide a detailed account of this material, including collection data, taxonomic updates, measurements and high-resolution images for species that are either poorly or not at all illustrated. Most specimens (70%) were collected in Africa as part of colonial expeditions or field surveys but there are also types from Western Asia (11%), and North and South America (19%). We provide an overview of the history of this collection, including a summary of the field surveys during which the specimens were collected and the arachnologists who described the material. Overall, this is the third-largest collection of solifuges in Germany with a distinct biogeographical focus and one of the largest collections of camel spiders in Europe.

This book is a detailed study of recent changes in security threats and defense forces in China, Taiwan, Japan, South Korea, and North Korea. The author argues that East Asia is in the midst of an arms race “of unprecedented scale” (p. 231). The major threats (“flashpoints”) in the region are the tensions between North and South Korea, the conflict between the People's Republic of China and the Republic of China over the future of Taiwan, and the competing claims to oil and other natural resources in the South China Sea. The range and character of these threats have not changed appreciatively in recent years, but what has changed are capabilities of militaries to project power, threaten neighbors, and destabilize the region.

Abstract Fungi of the genus Geosmithia are frequently associated with bark beetles that feed on phloem on various woody hosts. Most studies on Geosmithia were carried out in North and South America and Europe, with only two species were reported from Taiwan, China. The aim of this study was to investigate the diversity of Geosmithia species in southern China. Field surveys in Guangdong, Guangxi, Hunan, Jiangxi and Shanghai yielded a total of 76 fungal isolates from six beetle species. Isolates were grouped based on morphology. The ITS, β-tubulin and elongation factor 1-α gene regions of representatives of each group were sequenced. Phylogenetic trees were constructed based on those sequences. In total five species were identified, with one previously described species G. putterillii and four new species which were described as G. jiulianshanensis, G. jiangxiensis, G. formosana, and G. pulverea (Geosmithia sp. 3 and Geosmithia sp. 23) sp. nov., in this paper.

The current prevalence of pediatric Celiac Disease (CD) is estimated to be around 1% in the general population, worldwide. However, according to the geographic area, a great variability of CD prevalence has been described. Whereas a number of studies are available from Europe, North and South America, Australia, South-West Asia, and North Africa, the knowledge and awareness of CD in large parts of the remaining world areas is definitively poor. In several countries of Central and East Asia, the consumption of wheat is consistent and/or has significantly increased in recent decades, and CD is supposed to be underdiagnosed in children. In this mini-review, we aimed to summarize the current knowledge about the prevalence of pediatric CD in Central and East Asia, paying attention to the HLA-DQ immunogenetic background as well. Indeed, CD is likely not to be as uncommon as previously or currently thought in countries like Russia, Kazakhstan, and China, in addition to India, where pediatric CD has been clearly showed to be quite prevalent. Therefore, there is an urgent need for population-based studies on the prevalence of CD in those countries, especially in children, in order to increase the awareness of this disease and to improve the diagnostic strategy in these areas.
