Controlled experiments have shown that global changes decouple the biogeochemical cycles of carbon (C), nitrogen (N), and phosphorus (P), resulting in shifting stoichiometry that lies at the core of ecosystem functioning. However, the response of soil stoichiometry to global changes in natural ecosystems with different soil depths, vegetation types, and climate gradients remain poorly understood. Based on 2,736 observations along soil profiles of 0-150 cm depth from 1955 to 2016, we evaluated the temporal changes in soil C-N-P stoichiometry across subtropical China, where soils are P-impoverished, with diverse vegetation, soil, and parent material types and a wide range of climate gradients...

Argument Scholars of modern Chinese publishing and book culture focus on the dramatic transformations that took place in the late nineteenth and early twentieth centuries: the new technologies that enabled "mass" printing and the development of "modern" genres of print. They often neglect the fact that xylography remained a working technology through much of the Republican period and even into the People's Republic of China. Here I examine the continued use of woodblock printing and the continuing popularity of "traditional" textual genres from two perspectives...

BACKGROUND: Species of Schellackia Reichenow, 1919 have been described from the blood of reptiles distributed worldwide. Recently, Schellackia spp. detected in European and Asian lizards have been molecularly characterised. However, parasites detected in American lizard hosts remain uncharacterised. Thus, phylogenetic affinities between the Old and New World parasite species are unknown. METHODS: In the present study, we characterised morphologically and molecularly the hemococcidian parasites (sporozoites) that infect three lizard hosts from North America and two from South America...

Drought is a critical issue, and it has a pressing, negative impact on agriculture, ecosystems, livelihoods, food security, and sustainability. The problem has been studied globally, but its regional or even local dimension is sometimes overlooked. Local-level drought assessment is necessary for developing adaptation and mitigation strategies for that particular region. Keeping this in understanding, an attempt was made to create a detailed assessment of drought characteristics at the local scale in Bangladesh...

Toxoplasma gondii is a ubiquitous zoonotic pathogen belonging to apicomplexan parasites. Infection in humans and animals may cause abortion and other severe symptoms under certain circumstances, leading to great economical losses and public health problems. T. gondii was first discovered in China in 1955 and the corresponding work was published in 1957. Since then, a lot of work has been done on this parasite and the diseases it causes. This review summarizes the major progress made by Chinese scientists over the last 60 years, and gives our perspectives on what should be done in the near future...

The Spondweni serogroup of viruses (Flaviviridae, Flavivirus) is comprised of Spondweni virus (SPONV) and Zika virus (ZIKV), which are mosquito-borne viruses capable of eliciting human disease. Numerous cases of ZIKV sexual transmission in humans have been documented following the emergence of the Asian genotype in the Americas. The African ZIKV genotype virus was previously implicated in the first reported case of ZIKV sexual transmission. Reports of SPONV infection in humans have been associated with non-specific febrile illness, but no association with sexual transmission has been reported...

Uveal melanoma is the most common primary intraocular malignancy in adults. And there is an absence of targeted agents for patients with uveal melanoma. Pyrvinium pamoate is an old anthelminthic medicine approved by FDA for the treatment of enterobiasis in 1955, which recently re-attracts attention as an anti-cancer drug due to its inhibition of Wnt/β-catenin pathway in some types of cancer. But the role of pyrvinium pamoate in uveal melanoma and the potential underlying mechanism remains unknown. In this study, we tested the anti-tumor effects of pyrvinium pamoate on four uveal melanoma cell lines (92...

In June 2017 we celebrate the 90th anniversary of the pioneer discovery of cerebral angiography, the seminal imaging technique used for visualizing cerebral blood vessels and vascular alterations as well as other intracranial disorders. Egas Moniz (1874-1955) was the first to describe the use of this revolutionary technique which, until 1975 (when computed tomography, CT, scan was introduced in the clinical practice), was the sole diagnostic tool to provide an imaging of cerebral vessels and therefore alterations due to intracranial pathology...

Henry Wade graduated in the Edinburgh Medical School in 1898 before spending two years with the British army during the Anglo-Boer war. Returning to this country, he joined Francis Caird, surgeon to the Edinburgh Royal Infirmary. Appointed Conservator of the museum of the Royal College of Surgeons of Edinburgh, Wade met young William Ford Robertson. In a study of experimental cancer they concluded that some neoplasms were caused by bacteria. Wade became increasingly recognised as an authority in urology. His growing practice was interrupted by the First World War...

Severe methylmercury poisoning occurred in Minamata and neighboring communities in Japan during the 1950s and 1960s, causing what is known as Minamata disease. Although an increase in stillbirths and a reduced male proportion at birth (i.e., reduced sex ratio) have been reported, no studies have evaluated the impact of exposure on an entire set of infant and birth outcomes. We therefore evaluated the temporal trends of these outcomes in the Minamata area from 1950 to 1974. We focused on the spontaneous/artificial stillbirth rate, crude fertility rate, male proportion at birth, male proportion among stillbirths, and infant mortality...

Yosioka and Kawasima gave a widely used approximation for the acoustic radiation force on small liquid spheres surrounded by an immiscible liquid in 1955. Considering the liquids to be inviscid with negligible thermal dissipation, in their approximation the force on the sphere is proportional to the sphere's volume and the levitation position in a vertical standing wave becomes independent of the size. The analysis given here introduces a small correction term proportional to the square of the sphere's radius relative to the aforementioned small-sphere force...

Background and Objectives: Korean baby boomers (born 1955-1963) comprise the largest segment of the population approaching old age in Korea, and the majority is married or partnered. However, little is known about how couples share subjective aging experiences and how their self-perceptions of aging are associated with family experiences in midlife. Research Design and Methods: We analyzed 727 couples from the Korean Baby Boomer Panel Study. Using Actor-Partner Interdependence Model, we investigated whether major health problems within a family and marital quality were associated with perceptions of aging and future time...

Hepatitis B vaccine escape variants are the main threat to hepatitis B virus (HBV) infection in vaccination era worldwide. With 215 genotype B HBV and 313 genotype C HBV vaccine escape variants isolated from China during 2000-2016, we reported that genotype B HBV vaccine escape strains diverged in ∼1997 (95% HPD; 1987-2005), while genotype C HBV vaccine escape strains diverged in ∼1976 (95% HPD; 1955-2003). Additionally, the p-distance of genotype C HBV vaccine escape strains was 0.0291±0.0169, which was significantly higher than that in the genotype B HBV (t=131...

Methylmercury, the causative agent of Minamata disease, can easily penetrate the brain, and adult-type Minamata disease patients showed neurological symptoms according to the brain regions where the neurons, mainly in the cerebrum and cerebellum, were damaged. In addition, fetuses are exposed to methylmercury via the placenta from maternal fish consumption, and high-level exposure to methylmercury causes damage to the brains of infants. Typical patients with fetal-type Minamata disease (i.e., serious poisoning caused by in utero exposure to methylmercury) were born during the period of severe methylmercury pollution in 1955-1959, although they showed no abnormality during gestation nor at delivery...

B chromosomes are apparently dispensable components found in the genomes of many species that are mainly composed of repetitive DNA sequences. Among the numerous questions concerning B chromosomes, the origin of these elements has been widely studied. To date, supernumerary chromosomes have been identified in approximately 60 species of fish, including species of the genus Characidium Reinhardt, 1867 in which these elements appear to have independently originated. In this study, we used molecular cytogenetic techniques to investigate the origin of B chromosomes in a population of Characidium alipioi Travassos, 1955 and determine their relationship with the extra chromosomes of other species of the genus...
