Pulmonary fibrosis, a potentially fatal disease, results from acute and chronic interstitial lung diseases. Fucoxanthin (Fx), a carotenoid found in brown seaweed, shows a wide range of pharmacological activities. In this study, we investigated the antifibrotic effects of fucoxanthin and their underlying molecular mechanisms in transforming growth factor-beta1 (TGF-β1)-stimulated human pulmonary fibroblasts (HPFs). Thus, the effects of Fx on TGF-β1-induced expression of fibrotic factors, such as alpha-smooth muscle actin (α-SMA), type 1 collagen, fibronectin, and interleukin-6 (IL-6), in HPFs were investigated...

OBJECTIVE: Stereotactic body radiation therapy (SBRT) for the treatment of a malignancy in the liver requires the perilesional implantation of fiducial markers for lesion detection. The purpose of this study is to evaluate the efficacy and safety of ultrasound (US) -guided marker implantation for SBRT. METHODS: We retrospectively reviewed 299, US-guided, intrahepatic fiducial markers implanted in 101 patients between November 2013 and September 2014. SBRT-planning CT images were analyzed to determine the technical success of the implantation, the mean distance between the tumor margin and the marker, with the ideal location of fiducials defined as the distance between a marker and a tumor less than 3 cm and the distance between markers greater than 2 cm according to the tumor conspicuity seen on gray-scale US and the artifact obscuring tumor margins...

Here, we report the effect of Fe(CO)5 additives in the synthesis of branched Pt-CoO nanowires (NWs) and core@shell concave nanocubes (NCs), in a one-pot system. Key to the success of this synthesis is control over the shape of the Pt seeds by controlling the quantity of Fe(CO)5 additive. In the absence of Fe(CO)5, branched Pt-CoO NWs were synthesized through the attachment of small Pt seed particles, followed by the growth of CoO by deposition. On the other hand, Pt@CoO concave NCs were obtained in the presence of Fe(CO)5 because of the stronger adsorption of Co on the Pt (100) surfaces than on the closely packed (111) surfaces...

Elevated expression of preferentially expressed antigen in melanoma (PRAME) has been implicated in disease progression in a variety of cancers. However, the mechanisms underlying the transcriptional regulation of PRAME remain largely unexplored. Initially, we observed that PRAME was elevated in proportion to the malignant potential of melanoma cells. From the in silico prediction of PRAME gene structure, we identified the putative myeloid zinc finger 1 (MZF1) binding sites, which overlap with a CpG-rich region located in the first intron...

Hepatitis caused by hepatitis E virus (HEV) is a public health concern worldwide. HEV strains have been isolated from several animal species, some of which induce zoonosis. Recently, the isolation of HEV from rabbits was reported. Here, the partial capsid gene (320 bp) of HEV was detected in rabbit feces via reverse transcriptase-polymerase chain reaction (RT-PCR). Rabbit HEV was found in two of six rabbit farms and 17 of 264 rabbit fecal samples (6.4%). A phylogenetic analysis of the partial capsid gene classified the 17 HEV isolates into the putative rabbit HEV clade...

The Klebsiella oxytoca was engineered to produce 2,3-butanediol (2,3-BDO) simultaneously utilizing glucose and galactose obtained from a Golenkinia sp. hydrolysate. For efficient uptake of galactose at a high concentration of glucose, Escherichia coli galactose permease (GalP) was introduced, and the expression of galP under a weak-strength promoter resulted in simultaneous consumption of galactose and glucose. Next, to improve the sugar consumption, a gene encoding methylglyoxal synthase (MgsA) known as an inhibitor of multisugar metabolism was deleted, and the mgsA-null mutant showed much faster consumption of both sugars than the wild-type strain did...

G-protein-coupled receptor 119 (GPR119) represents a promising target for the treatment of type 2 diabetes as it can increase both GLP-1 secretion from intestinal L cells and glucose-stimulated insulin secretion (GSIS) from pancreatic β cells. Due to this dual mechanism of action, the development of small molecule GPR119 agonists has received much interest for the treatment of type 2 diabetes. Here, we identified a novel small-molecule GPR119 agonist, YH18421 and evaluated its therapeutic potential. YH18421 specifically activated human GPR119 with high potency and potentiated GLP-1 secretion and GSIS in vitro cell based systems...

A 20-year-old man presented with a femur fracture and epidural hemorrhage (EDH) following a fall. One month after fracture surgery, swelling developed in both legs, and he was diagnosed as having a deep-vein thrombosis and pulmonary embolism. A retrievable inferior vena cava filter (IVCF) was inserted, because EDH is a contraindication to anticoagulants. Four months later, he complained of abdominal pain, and a computed tomography scan showed a fractured IVCF strut. After percutaneous removal failed 3 times, the IVCF was surgically removed by orthopedists using a portable image intensifier without cardiopulmonary bypass...
