88% (390/1118), and the highest rates were 41.24% in children three years of age. There was a higher detection rate in humans with diarrhea (53.68%). Five potentially zoonotic subtypes (ST1, ST2, ST3, ST5, and ST9) were identified; among these, ST1 and ST2 were more prevalent than others in non-human primates. Similarly, two subtypes (ST2 and ST5) were detected in humans and ST2 was also the most prevalent. To the best of our knowledge, this is the first report of the prevalence and subtype composition of Blastocystis sp. in Hebei province, and the first study concerning the relationship of Blastocystis sp. among primates in China. The findings of the study will improve our understanding of the genetic diversity and public health potential of Blastocystis sp. enteric infections in addition to providing a profile of subtype characteristics of Blastocystis sp. in primates of Northern China.Antheraea pernyi is a semi-domesticated lepidopteran insect species valuable to the silk industry, human health, and ecological tourism. Owing to its economic influence and developmental properties, it serves as an ideal model for investigating divergence of the Bombycoidea super family. However, studies on the karyotype evolution and functional genomics of A. pernyi are limited by scarce genomic resource. Here, we applied PacBio sequencing and chromosome structure capture technique to assemble the first high-quality A. pernyi genome from a single male individual. The genome is 720.67 Mb long with 49 chromosomes and a 13.77-Mb scaffold N50. Approximately 441.75 Mb, accounting for 60.74% of the genome, was identified as repeats. The genome comprises 21,431 protein-coding genes, 85.22% of which were functionally annotated. Comparative genomics analysis suggested that A. pernyi diverged from its common ancestor with A. yamamai ~30.3 million years ago, and that chromosome fission contributed to the increased chromosome number. The genome assembled in this work will not only facilitate future research on A. pernyi and related species but also help to progress comparative genomics analyses in Lepidoptera.Background Testicular ultrasound (US) is routinely employed in the evaluation of reproductive and sexual function. However, its use for characteristics other than testicular volume is hampered by a lack of information on the prognostic value of its findings, which to date have only been incorporated in a score proposed by Lenz et al. in 1993. Objectives We sought to explore whether testicular US examination can predict the quality of spermatogenesis and provide information on testicular endocrine function. Materials and methods We retrospectively reviewed 6210 testicular US examinations, finally selecting examinations from 2230 unique men. The following variables were considered bitesticular volume and testicular asymmetry, parenchymal echotexture, echogenicity and presence of microlithiasis, solid lesions and varicocele. MDMX inhibitor Concurrent fasting hormonal data were available for 1160 men, while 979 had a semen sample available from the same day as the US exam. Results We derived a new US score, termed TU score, that can predict both impaired spermatogenesis (AUC 0.73, sensitivity 72%, specificity 61%, p less then 0.001) and hypogonadism (AUC 0.71, sensitivity 71%, specificity 53%, p less then 0.001) more accurately than the Lenz's score. In a multivariate analysis, a reduced sperm composite index (defined as total spermatozoa x total motility x normal forms) was independently predicted by bitesticular volume and by inhomogeneous echotexture, while hypogonadism was independently predicted also by reduced echogenicity and presence of microlithiasis. Discussion and conclusions We describe the testicular US characteristics that are independently associated with impaired spermatogenesis and hypogonadism and propose the TU score as a simple screening method for use in subjects referred for testicular US.The interacting effects of global changes - including increased temperature, altered precipitation, reduced acidification, and increased dissolved organic matter loads to lakes - are anticipated to create favourable environmental conditions for cyanobacteria in northern lakes. However, responses of cyanobacteria to these global changes are complex, if not contradictory. We hypothesized that absolute and relative biovolumes of cyanobacteria (both total and specific genera) are increasing in Swedish nutrient-poor lakes and that these increases are associated with global changes. We tested these hypotheses using data from 28 nutrient-poor Swedish lakes over 16 years (1998-2013). Increases in cyanobacteria relative biovolume were identified in 21% of the study sites, primarily in the southeastern region of Sweden, and were composed mostly of increases from three specific genera Merismopedia, Chroococcus, and Dolichospermum. Taxon specific changes were related to different environmental stressors; i.e., increased surface water temperature favored higher Merismopedia relative biovolume in low pH lakes with high nitrogen to phosphorus ratios, whereas acidification recovery was statistically related to increased relative biovolumes of Chroococcus and Dolichospermum. In addition, enhanced dissolved organic matter loads were identified as potential determinants of Chroococcus suppression and Dolichospermum promotion. Our findings highlight that specific genera of cyanobacteria benefit from different environmental changes. Our ability to predict the risk of cyanobacteria prevalence requires consideration of the environmental condition of a lake and the sensitivities of the cyanobacteria genera within the lake. Regional patterns may emerge due to spatial autocorrelations with and among lake history, rates and direction of environmental change, and the niche space occupied by specific cyanobacteria.(1) Phosphate (Pi) deficiency severely restricts plant growth and development, as Pi is an essential macronutrient. Calcium (Ca2+ ) is a ubiquitous second messenger in plants, calcineurin B-like proteins (CBLs) and CBL-interacting protein kinases (CIPKs) signaling pathways act as one important Ca2+ signaling network which integrate plants to fine tune response to stresses, however, whether CIPKs are involved in Pi deficiency stress remains largely unknown. (2) In this study, we carried out a reverse genetic strategy to screen T-DNA insertion mutants of CIPKs isoforms under Pi deficiency in Arabidopsis thaliana. Then Pi content, transcription of phosphate starvation-induced (PSIs) genes, acid phosphatase activity and hydrogen peroxide were determined in wild-type and cipk1 mutant respectively. The phenotype of CIPK1 complementation lines was analyzed. (3) The cipk1 mutant exhibited a more sensitive phenotype, with shorter root elongation and root length, decreased Pi content compared with wild-type under Pi deficiency.
