Xishuangbanna is a popular tourist destination in southern Yunnan Province, bordering with Vietnam and Laos and Myanmar. There are more than 2 million cross-border travelers annually entering China at two land ports, Daluo and Mohan. To clarify the characteristics of HIV-1 prevalence among entry travelers, a retrospective epidemic investigation was conducted. Between 2003 and 2012, 196 among 91,432 entry travelers were detected to be HIV-1-positive, accounting for infection rate of 0.21%. Eighty-one gag-pol gene sequences were obtained for phylogenetic analyses and subsequent recombination analysis...

Hepatitis C virus (HCV) is a positive-sense single-stranded RNA virus with an estimated infection in ∼180 million people worldwide, and its chronic infection leads to development of cirrhosis and hepatocellular carcinoma. Although recent development of direct acting antiviral (DAA) compounds improved anti-HCV regimens, alternative therapeutic compounds are still demanded due to an expected emergence of escape mutants for those DAAs. In order to identify novel anti-HCV agents, we conducted chemical library screening for 2,086 compounds using HCV Rep-Feo reporter replicon in Huh7 hepatoma cells...

Chinese hamster ovary (CHO) cells, major mammalian host cells for biomanufacturing of therapeutic proteins, have been extensively investigated to enhance productivity and product quality. However, cell line instability resulting in unexpected changes in productivity or product quality is challenging for biomanufacturing. Based on previous reports about causes and characteristics of production instability, we hypothesized that chromosomal rearrangements due to genomic instability are associated with production instability...

Congenital hyperinsulinism (CHI) is the most common cause of severe persistent hypoglycemia in neonates and infants. Early diagnosis and effective treatment (based on the principles of pharmacogenetics) play the key role for the prognosis. The DNA anlysis, which can identify mutation in one of the 11 genes causing MODY, is crutial in the diagnostics. Moreover, The genotype determines also the optimal therapy approach (medicaments, diet or rarely surgery). There was a large progress of novel medicaments treating particularly most severe (diazoxide-resistant) forms of CHI...

There are several known and unknown factors for unexplained recurrent spontaneous abortion (URSA). Among them, complement regulatory protein CD46 plays a pivotal role in preventing uncontrolled activation of complement and successful continuation of pregnancy. We aimed in this study to investigate the possible association of CD46 IVS1-1724 C>G polymorphism with RSA in Iranian women. 141 women with RSA and 153 women with normal pregnancy were enrolled in this study. RSA was confirmed as the history of having at least three consecutive abortions without any known immunologic, pathologic and genetic reason...

The relative importance of interactions between mitochondrial and nuclear genes on adaptation has gained increased attention (see Wolff et al., 2014), although experimental systems to make direct tests of its importance are scarce. Mitonuclear epistasis is when nuclear and mitochondrial genes interact, often at the protein level, and variation in these interactions may result in phenotypic differences (Paliwal et al., 2014). These interactions are often found in the mitochondria where the energy-generating electron transport chain (ETC) is located, and consists of both nuclear and mitochondrial proteins...

Many viruses can cause respiratory diseases in humans. Although great advances have been achieved in methods of diagnosis, it remains challenging to identify pathogens in unexplained pneumonia (UP) cases. In this study, we applied next-generation sequencing (NGS) technology and a metagenomic approach to detect and characterize respiratory viruses in UP cases from Guizhou Province, China. A total of 33 oropharyngeal swabs were obtained from hospitalized UP patients and subjected to NGS. An unbiased metagenomic analysis pipeline identified 13 virus species in 16 samples...

Probabilistic graphical models show great potential for robust and reliable construction of linkage maps. We show how to use probabilistic graphical models to construct high-quality linkage maps in the face of data perturbations caused by genotyping errors and reciprocal translocations. It has been shown that linkage map construction can be hampered by the presence of genotyping errors and chromosomal rearrangements such as inversions and translocations. Here, we report a novel method for linkage map construction using probabilistic graphical models...

Progranulin deficiency is associated with neurodegeneration in humans and in mice. The mechanisms likely involve progranulin-promoted removal of protein waste via autophagy. We performed a deep proteomic screen of the pre-frontal cortex in aged (13-15 months) female progranulin-deficient mice (GRN(-/-)) and mice with inducible neuron-specific overexpression of progranulin (SLICK-GRN-OE) versus the respective control mice. Proteins were extracted and analyzed per liquid chromatography/mass spectrometry (LC/MS) on a Thermo Scientific™ Q Exactive Plus equipped with an ultra-high performance liquid chromatography unit and a Nanospray Flex Ion-Source...

Fillet yield (FY, %) is an economically-important trait in rainbow trout aquaculture that affects production efficiency. Despite that, FY has received little attention in breeding programs because it is difficult to measure on a large number of fish and cannot be directly measured on breeding candidates. The recent development of a high-density SNP array for rainbow trout has provided the needed tool for studying the underlying genetic architecture of this trait. A genome-wide association study (GWAS) was conducted for FY, body weight at 10 (BW10) and 13 (BW13) months post-hatching, head-off carcass weight (CAR), and fillet weight (FW) in a pedigreed rainbow trout population selectively bred for improved growth performance...

The interaction of elevated [CO2] and water stress will have an effect on the adaptation of durum wheat to future climate scenarios. For the Mediterranean basin these scenarios include the rising occurrence of water stress during the first part of the crop cycle. In this study, we evaluated the interactive effects of elevated [CO2] and moderate to severe water stress during the first part of the growth cycle on physiological traits and gene expression in four modern durum wheat genotypes. Physiological data showed that elevated [CO2] promoted plant growth but reduced N content...

Pearl millet [Penisetum glaucum (L) R. Br.] is a hardy cereal crop grown in the arid and semiarid tropics where other cereals are likely to fail to produce economic yields due to drought and heat stresses. Adaptive evolution, a form of natural selection shaped the crop to grow and yield satisfactorily with limited moisture supply or under periodic water deficits in the soil. Drought tolerance is a complex polygenic trait that various morphological and physiological responses are controlled by 100s of genes and significantly influenced by the environment...

Genomic selection (GS) unlike marker-assisted backcrossing (MABC) predicts breeding values of lines using genome-wide marker profiling and allows selection of lines prior to field-phenotyping, thereby shortening the breeding cycle. A collection of 320 elite breeding lines was selected and phenotyped extensively for yield and yield related traits at two different locations (Delhi and Patancheru, India) during the crop seasons 2011-12 and 2012-13 under rainfed and irrigated conditions. In parallel, these lines were also genotyped using DArTseq platform to generate genotyping data for 3000 polymorphic markers...

Late-onset progressive cerebellar ataxia is a diagnostic challenge because of a poor correlation between genotype and phenotype, and a broad range of secondary causes that extend beyond the neurological field. We report the case of a 45-year-old woman admitted after 2 years of slowly progressing cerebellar ataxia, dysarthria, and emotional instability. Notably, she was diagnosed with diabetes insipidus at the age of 35. As 'idiopathic cerebellar ataxia' was suspected, diagnostic tests, including genetic testing as well as serum and cerebrospinal fluid analyses, and brain magnetic resonance imaging (MRI) were performed...

Gilles de la Tourette syndrome (GTS) is a neuropsychiatric disorder characterized by multiple motor and vocal tics. GTS is a complex disorder, with environmental factors and several genes involved. Although variations within a few genes such as AADAC, NRXN1, SLITRK1, HDC, and IMMP2L have been tentatively associated with GTS (in a small number of patients), the causative genes underlying GTS pathophysiology remain unknown. In a previous genome-wide association study (GWAS) a single nucleotide polymorphism (SNP, rs2060546) near the Netrin-4 (NTN4 - MIM 610401) gene was shown to be associated with GTS [odds ratio (OR) = 1...

Background: There are limited treatments available for autism spectrum disorder (ASD). Studies have reported significant associations between the receptor genes of oxytocin (OT) and vasopressin (AVP) and ASD diagnosis, as well as ASD-related phenotypes. Researchers have also found the manipulation of these systems affects social and repetitive behaviors, core characteristics of ASD. Consequently, research involving the oxytocin/vasopressin pathways as intervention targets has increased. Therefore, further examination into the relationship between these neuropeptides and ASD was undertaken...
