#1
Dong-Xiu Xue, Yu-Long Li, Jin-Xian Liu
As one of the most informative and versatile DNA-based markers, microsatellites have been widely used in population and conservation genetic studies. However, the development of microsatellites has traditionally been laborious, time-consuming, and expensive. In the present study, a rapid and cost-effective "RAD-seq-Assembly-Microsatellite" approach was developed to identify abundant microsatellite markers in non-model species using the roughskin sculpin Trachidermus fasciatus as a representative. Overlapping paired-end Illumina reads generated by restriction-site-associated DNA sequencing (RAD-seq) were clustered based on the similarity of reads containing the restriction enzyme recognition site and then assembled into contigs, which were used for microsatellite discovery and primer design...

Player-to-player contact inherent in many unhelmeted sports means that head impacts are a frequent occurrence. Model-Based Image-Matching (MBIM) provides a technique for the assessment of three-dimensional linear and rotational motion patterns from multiple camera views of a head impact event, but the accuracy is unknown for this application. The goal of this study is to assess the accuracy of the MBIM method relative to reflective marker-based motion analysis data for estimating six degree of freedom head displacements and velocities in a staged pedestrian impact scenario at 40 km/h...

BACKGROUND: One of the overarching goals of soybean breeding is to develop lines that combine increased yield with improved quality characteristics. High-density-marker QTL mapping can serve as an effective strategy to identify novel genomic information to facilitate crop improvement. In this study, we genotyped a recombinant inbred line (RIL) population (Zhonghuang 24 × Huaxia 3) using a restriction-site associated DNA sequencing (RAD-seq) approach. A high-density soybean genetic map was constructed and used to identify several QTLs that were shown to influence six yield-related and two quality traits...

Population genetic studies in nonmodel organisms are often hampered by a lack of reference genomes that are essential for whole-genome resequencing. In the light of this, genotyping methods have been developed to effectively eliminate the need for a reference genome, such as genotyping by sequencing or restriction site-associated DNA sequencing (RAD-seq). However, what remains relatively poorly studied is how accurately these methods capture both average and variation in genetic diversity across an organism's genome...

Patients with hepatocellular carcinoma (HCC) may be eligible for liver transplantation. Liver transplant candidates with HCC compete for the same deceased donor organs as those without HCC. These scarce organs must be allocated fairly and justly to those who will benefit most. Unlike most other cancers, HCC is often diagnosed noninvasively by imaging without biopsy confirmation. Therefore, radiologists play an important role in diagnosing definite HCC (i.e., LR-5 category) that counts toward staging and determination of liver transplant eligibility...

Since the identification of R-Ras, which is the first Ras-related GTPase isolated based on sequence similarity to the classical RAS oncogene, more than 160 members of the Ras superfamily of GTPases have been identified and classified into the Ras, Rho, Rap, Rab, Ran, Arf, Rheb, RGK, Rad, Rit, and Miro subfamilies. R-Ras belongs to the Ras subfamily of small G-proteins, which are frequently implicated in cell growth and differentiation. Although the roles of R-Ras in cellular transformation and integrin-mediated cell adhesion have been extensively studied, the physiological function of this enigmatic G-protein was only revealed when a mouse strain deficient in R-Ras was generated...

Intrahepatic cholangiocarcinoma (ICC) is a highly malignant, heterogeneous cancer with poor treatment options. We found that mitochondrial dysfunction and oxidative stress trigger a niche favoring cholangiocellular overgrowth and tumorigenesis. Liver damage, reactive oxygen species (ROS) and paracrine tumor necrosis factor (Tnf) from Kupffer cells caused JNK-mediated cholangiocellular proliferation and oncogenic transformation. Anti-oxidant treatment, Kupffer cell depletion, Tnfr1 deletion, or JNK inhibition reduced cholangiocellular pre-neoplastic lesions...

This study suggested successful encapsulation of polyhexamethylene biguanide chloride (PHMB) into nano cationic liposome as a biocompatible antibacterial agent with less cytotoxicity and higher activities. Phosphatidylcholine, cholesterol and stearylamine were used to prepare nano cationic liposome using thin film hydration method along with sonication or homogeniser. Sonication was more effective in PHMB loaded nano cationic liposome preparation with smaller size (34 nm). FTIR, (1)H NMR and XRD analyses were used to confirm the encapsulation of PHMB into nano cationic liposome...
