  • Open reading frame 35 (bm35) of the Bombyx mori nucleopolyhedrovirus (BmNPV) is a special gene whose homologues are only found in some group-I nucleopolyhedroviruses, suggesting that bm35 plays a specific role in the viral life cycle. This paper described the characterization of BmNPV bm35. Computerassisted sequence analysis shows that a putative RING finger motif is observed in the protein, Bm35 encoded by bm35. The coding sequence of bm35 was amplified and subcloned into the vector pET30a(+) and the $(His)_6$-tagged fusion protein His-Bm35 was expressed in the Escherichia coli BL21 (DE3) LysS cells. The bm35 transcript and Bm35 protein were detected in BmNPV-infected BmN cells at 12~48 h post infection (p.i.) by RT-PCR and Western blot analysis using the polyclonal antibody generated by immunizing a rabbit with purified $(His)_6$-tagged Bm35, suggesting that bm35 is synthesized in the late stage of BmNPV infection cycle. Bm35 was not a structural component associated with budded virus (BV) and occlusion derived virus (ODV). These data indicated that bm35 is a functional gene in the BmNPV life cycle.

  • In this paper, a new $Co_{10}Fe_{10}Mn_{35}Ni_{35}Zn_{10}$ high entropy alloy (HEA) is identified as a strong candidate for the single face-centered cubic (FCC) structure screened using the upgraded TCFE2000 thermodynamic CALPHAD database. The $Co_{10}Fe_{10}Mn_{35}Ni_{35}Zn_{10}$ HEA is fabricated using the mechanical (MA) procedure and pressure-less sintering method. The $Co_{10}Fe_{10}Mn_{35}Ni_{35}Zn_{10}$ HEA, which consists of elements with a large difference in melting point and atomic size, is successfully fabricated using powder metallurgy techniques. The MA behavior, microstructure, and mechanical properties of the $Co_{10}Fe_{10}Mn_{35}Ni_{35}Zn_{10}$ HEA are systematically studied to understand the MA behavior and develop advanced techniques for fabricating HEA products. After MA, a single FCC phase is found. After sintering at $900^{\circ}C$, the microstructure has an FCC single phase with an average grain size of $18{\mu}m$. Finally, the $Co_{10}Fe_{10}Mn_{35}Ni_{35}Zn_{10}$ HEA has a compressive yield strength of 302 MPa.

  • A previous pharmacogenomic analysis identified cromolyn, an anti-allergic drug, as an effective anti-fibrotic agent that acts on hepatocytes and stellate cells. Furthermore, cromolyn was shown to be a G protein-coupled receptor 35 (GPR35) agonist. However, it has not been studied whether anti-fibrotic effects are mediated by GPR35. Therefore, in this study, the role of GPR35 in hepatic fibrosis was investigated through the use of lodoxamide, another anti-allergic drug and a potent GPR35 agonist. Long-term treatment with carbon tetrachloride induced hepatic fibrosis, which was inhibited by treatment with lodoxamide. Furthermore, CID2745687, a specific GPR35 antagonist, reversed lodoxamide-mediated anti-fibrotic effects. In addition, lodoxamide treatment showed significant effects on the mRNA expression of collagen Iα1, collagen Iα2, and TGF-β1 in the extracellular matrix. However, a transforming growth factor α (TGF-α) shedding assay revealed lodoxamide not to be a potent agonist of mouse GPR35 in vitro. Therefore, these results showed anti-fibrotic effects of lodoxamide in mice and raise concerns how lodoxamide protects against liver fibrosis in vivo and whether GPR35 is involved in the action.

  • The present study aims to investigate the effect of methanol extract of Korean mistletoe (KM; Viscum album var. coloratum), on amyloid $\beta$ protein ($A\beta$) (25-35), a synthetic 25-35 amyloid peptide, -induced neurotoxicity in cultured rat cerebral cortical neurons and memory impairment in mice. Exposure of cultured neurons to $10{\mu}M$ $A\beta$ (25-35) for 24 h induced a neuronal cell death, which was measured by a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay and Hoechst 33342 staining. KM (10, 30 and $50{\mu}g/ml$) significantly inhibited the $A\beta$ (25-35)-induced apoptotic neuronal death. KM ($50{\mu}g/ml$) inhibited 10 μM Aβ (25-35)-induced elevation of intracellular calcium concentration ([Ca2+]i), which was measured by a fluorescent dye, Fluo-4 AM. Glutamate release into medium and generation of reactive oxygen species (ROS) induced by $10{\mu}M$ $A\beta$ (25-35) were also inhibited by KM (10, 30 and $50{\mu}g/ml$). These results suggest that KM may mitigate the $A\beta$ (25-35)-induced neurotoxicity by interfering with the increase of [Ca2+]i and then inhibiting glutamate release and generation of ROS in cultured neurons. In addition, orally administered KM (25 and 50 mg/kg, 7 days) significantly prevented memory impairment induced by intracerebroventricular injection of $A\beta$ (25-35) (8 nmol). Taken together, it is suggested that anti-dementia effect of KM is due to its neuroprotective effect against $A\beta$ (25-35)-induced neurotoxicity and that KM may have therapeutic role in prevention of the progression of Alzheimer's disease.

  • Amyloid peptide (A${\beta}$) is the major component of senile plaques found in the brain of patient of Alzheimer's disease. ${\beta}$-amyloid peptide (25-35) (A${\beta}$25-35) is biologically active fragment of A${\beta}$. The three-dimensional structure of A${\beta}$25-35 in aqueous solution with 50% (vol/vol) TFE determined by NMR spectroscopy previously adopts an ${\alpha}$-helical conformation from $Ala^{30}$ to $Met^{35}$. It has been proposed that A${\beta}$(25-35) exhibits pH- and concentration-dependent ${\alpha}-helix{\leftrightarrow}{\beta}$sheet transition. This conformational transition with concomitant peptide aggregation is a possible mechanism of plaque formation. Here, in order to gain more insight into the mechanism of ${\alpha}$-helix formation of A${\beta}$25-35 peptide by TFE, which particularly stabilizes ${\alpha}$-helical conformation, we studied the secondary-structural elements of A${\beta}$25-35 peptide by molecular dynamics simulations. Secondary structural elements determined from NMR spectroscopy in aqueous TFE solution are preserved during the MD simulation. TFE/water mixed solvent has reduced capacity for forming hydrogen bond to the peptide compared to pure water solvent. TFE allows A${\beta}$25-35 to form bifurcated hydrogen bonds to TFE as well as to residues in peptide itself. MD simulation in this study supports the notion that TFE can act as an ${\alpha}$-helical structure forming solvent.

  • We have cloned and characterized an antiapoptotic gene, p35, which blocks apoptosis, from Bombyx mori nuclear polyhedrosis virus (BmNPV) K1 strain. The 897 bp p35 has an open reading frame of 299 amino acids. The BmNPV-K1 p35 showed a high identity to Autographa californica nuclear polyhedrosis virus and BmNPV T3 strain. The BmNPV-K1 p35 was different from the amino acid sequences of BmNPV T3 at 6 positions. The p35 gene of BmNPV-K1 was 99.2% identical at the nucleotide level and 98% identical at the amino acid level to BmNPV T3. The location of p35 gene in the BmNPV-K1 genome was confirmed by Southern blot analysis and its expression patterns at the transcriptional level in the infected cells were con- firmed by Northern hybridization analysis.

  • IL-12 is a secretory heterodimeric cytokine composed of p35 and p40 subunits. IL-12 p35 and p40 subunits are sometimes produced as monomers or homodimers. IL-12 is also produced as a membrane-bound form in some cases. In this study, we hypothesized that the membrane-bound form of IL-12 subunits may function as a costimulatory signal for selective activation of TAA-specific CTL through direct priming without involving antigen presenting cells and helper T cells. MethA fibrosarcoma cells were transfected with expression vectors of membrane-bound form of IL-12p35 (mbIL-12p35) or IL-12p40 subunit (mbIL-12p40) and were selected under G418-containing medium. The tumor cell clones were analyzed for the expression of mbIL-12p35 or p40 subunit and for their stimulatory effects on macrophages. The responsible T-cell subpopulation for antitumor activity of mbIL-12p35 expressing tumor clone was also analyzed in T cell subset-depleted mice. Expression of transfected membranebound form of IL-12 subunits was stable during more than 3 months of in vitro culture, and the chimeric molecules were not released into culture supernatants. Neither the mbIL-12p35-expressing tumor clones nor mbIL-12p40-expressing tumor clones activated macrophages to secrete TNF-${\alpha}$. Growth of mbIL-12p35-expressing tumor clones was more accelerated in the $CD8^+$ T cell-depleted mice than in $CD4^+$ T cell-depleted or normal mice. These results suggest that $CD8^+$ T cells could be responsible for the rejection of mbIL-12p35-expressing tumor clone, which may bypass activation of antigen presenting cells and $CD4^+$ helper T cells.

  • A superconductor flywheel energy storage system (SFES) is an electro-mechanical battery which transforms electrical energy into mechanical energy for storage, and vice versa. A 35 kWh class SFES module was designed and constructed as part of a 100kWh/1MW class SFES composed of three 35 kWh class SFES modules. The 35 kWh class SFES is composed of a main frame, superconductor bearings, a composite flywheel, a motor/generator, electro-magnetic bearings, and a permanent magnet bearing. The high energy density composite flywheel is levitated by the permanent magnet bearing and superconductor bearings, while being spun by the motor/generator, and the electro-magnetic bearings are activated while passing through the critical speeds. Each of the main components was designed to provide maximum performance within a space-limited compact frame. The 35 kWh class SFES is designed to store 35 kWh, with a 350 kW charge/discharge capacity, in the 8,000 ~ 12,000 rpm operational speed range.

  • Objectives: To compare the clinicalpathological features and prognosis between premenopausal breast cancer patients aged of <35 and ${\geq}35$ years old. Methods: The clinical data and survival status of 1498 cases premenopausal operable breast cancer treated in our hospital from 2002.1 to 2004. 12 were collected, 118 cases were aged <35. They were divided into 4 groups: Luminal A, Luminal B, HER2-positive, Triple-negative. The disease free survival (DFS) and overall survival (OS) were identified. Results: The 5-year DFS and OS rates were significantly lower in age<35 than in $age{\geq}35$ patients. In the Luminal B, HER2-positive, Triple-negative group, the 5-year recurrence risk was higher in age<35 than in $age{\geq}35$ patients, and age<35 patients' 5-year death risk was higher only in Luminal B, Triple-negative group. Regardless of whether lymph node involved, age<35 patients had a bad prognosis in both DFS and OS. Conclusions: Compared with premenopausal age ${\geq}35$ breast cancer, age<35 patients had a worse outcome.
