Modification of artificial sea water for the mass production of (+)-terrein by Aspergillus terreus strain PF26 derived from marine sponge Phakellia fusca. Lett Appl Microbiol 2015; 61:580-7.

Abstract
UNLABELLED (+)-Terrein shows multiple bioactivities, however, its mass production is a big challenge. Aspergillus terreus strain PF26 derived from South China Sea sponge Phakellia fusca has been cultured to produce (+)-terrein successfully, but artificial sea water (ASW) of high salinity used in the fermentation medium may cause the corrosion risk of metal bioreactor, which limits the fermentation on a large scale. In this study, we modified the components of ASW by removing NaCl and CaCl2 from the original formula, which reduced about 80% salinity of ASW. As a result, 7·56 g l(-1) (+)-terrein production was achieved in shake flask, which was 78·72% higher than using the original ASW, and the cultivation time was decreased from 24 to 15 days. Then, the modified ASW was used for the fermentation of A. terreus strain PF26 in a 500 l stirred bioreactor, consequently 2·5 g l(-1) of (+)-terrein production was achieved. SIGNIFICANCE AND IMPACT OF THE STUDY The fermentation of marine micro-organisms always needs to use sea water or artificial sea water (ASW), which limits the fermentation on a large scale, as the high-salinity medium may cause the corrosion risk of bioreactor. In this study, the ASW formula is simplified to reduce the sea water salinity and improve the yield of (+)-terrein, finally, the modified ASW was successfully used for the mass production of (+)-terrein by A. terreus strain PF26 in a 500 l bioreactor.

Abstract
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Z_{c}(3900)^{0} with a significance of 10.4σ. The mass and width are measured to be 3894.8±2.3±3.2 MeV/c^{2} and 29.6±8.2±8.2 MeV, respectively, where the first error is statistical and the second systematic. The Born cross section for e^{+}e^{-}→π^{0}π^{0}J/ψ and the fraction of it attributable to π^{0}Z_{c}(3900)^{0}→π^{0}π^{0}J/ψ in the range E_{c.m.}=4.19-4.42 GeV are also determined. We interpret this state as the neutral partner of the four-quark candidate Z_{c}(3900)^{±}.

Abstract
BACKGROUND The heritability of suicide is well established. Transmission of risk appears to follow traits more than disorders like depression. In the present project, we aimed at investigating the potential for transmission of cognitive deficits previously observed in suicide attempters, specifically impaired decision-making and cognitive control. METHODS Seventeen healthy first-degree relatives of suicide completers with no personal history of suicidal act were compared to 18 first-degree relatives of individuals with major depressive disorder but no family history of suicidal act, and 19 healthy controls. Decision-making was assessed with the Iowa Gambling Task, and cognitive control with the Stroop Task, the Hayling Sentence Completion Test, and the Trail-Making Test. RESULTS Both suicide and depressed relatives showed lower gambling task net scores than healthy controls. However, there were trends toward lower learning abilities in suicide than depressed relatives (interaction: p = 0.07), with more risky choices at the end of the test. Suicide relatives also showed a higher number of self-corrected errors relative to the total number of errors in the Stroop colour test compared to both control groups, with no difference in interference scores. There was no group-difference for any other cognitive tests. CONCLUSION Our findings suggest that decision-making impairment may be found in healthy relatives of suicides and represent a cognitive endophenotype of suicidal behaviour. Normal cognitive control (or self-corrected deficits) may protect relatives against suicidal acts. Impairments in value-based and control processes may, therefore, be part of the suicide vulnerability and represent potential targets of preventative interventions.

Abstract
We evaluated the efficacy and safety of telbivudine (LdT, 600 mg/day) vs control patients (no treatment) in decreasing vertical transmission of HBV, in HBeAg-positive mothers (HBVDNA >6log(10) copies/mL). HBeAg-positive pregnant women either in the second or third trimester were recruited in a prospective, case-control, open-label study, at the Second Affiliated Hospital of the Southeast University, China (February 2008-December 2010). Efficacy (month 7: HBVDNA (+), HBsAg (+) infants) in either the overall group or the treated group and control group was analysed using student's t-test. Infants were followed for at least 1 year. 362 women received LdT (second trimester n = 257; third trimester n = 105) and 92 were untreated. Before delivery, the mean maternal HBVDNA was 2.73, 2.47, 3.34 and 7.94 log10 copies/mL in the overall, second and third trimester treated and control groups, respectively (P < 0.001). At birth, 11.8% of babies overall (43/365), 13.5% (35/259) of those treated in the second trimester, 7.5% of those treated in the third trimester (8/106) and 20.7% (19/92) of untreated infants were HBsAg positive. At month 7, none of the LdT-treated infant had detectable HBVDNA, while eight infants from control mothers were HBsAg positive. Vertical transmission was 0% in LdT treated and 9.3% (8/86) in the control groups (P < 0.001). No difference in the vertical transmission rate was found in mothers treated in the second or third trimester. LdT treatment was safe for mothers and infants, and no congenital deformities were reported.

Abstract
We report an observation of the process J/ψ→γX(1835)→γK_{S}^{0}K_{S}^{0}η at low K_{S}^{0}K_{S}^{0} mass with a statistical significance larger than 12.9σ using a data sample of 1.31×10^{9} J/ψ events collected with the BESIII detector. In this region of phase space the K_{S}^{0}K_{S}^{0} system is dominantly produced through the f_{0}(980). By performing a partial wave analysis, we determine the spin parity of the X(1835) to be J^{PC}=0^{-+}. The mass and width of the observed X(1835) are 1844±9(stat)_{-25}^{+16}(syst) MeV/c^{2} and 192_{-17}^{+20}(stat)_{-43}^{+62}(syst) MeV, respectively, which are consistent with the results obtained by BESIII in the channel J/ψ→γπ^{+}π^{-}η^{'}.

Abstract
We performed a study to evaluate X-ray repair cross-complementing protein 4 (XRCC4) gene polymorphisms and the development of pancreatic cancer. A case-control study including 206 patients with newly diagnosed primary pancreatic cancer and 412 controls was performed between January 2011 and October 2013 in a Chinese population. Genotypes of XRCC4 rs1805377, rs2075685, rs2075686 and rs1056503 were determined using polymerase chain reaction combined with a restriction fragment length polymorphism assay. Compared with controls, pancreatic cancer patients were more likely to have a higher body mass index, family history of cancer, and a habit of alcohol drinking compared with controls (P < 0.05). Logistic regression analysis showed that individuals carrying the TT genotype of XRCC4 rs2075685 had an increased risk of pancreatic cancer compared to those with the GG genotype, with an odds ratio (95% confidence interval) of 1.88 (1.15-3.08). Our results suggest that the XRCC4 rs2075685 polymorphism could influence the susceptibility to pancreatic cancer in a Chinese population.

Abstract
The Wiskott-Aldrich syndrome protein (WASp) is an important regulator of the actin cytoskeleton and is required for immune cell function. WASp deficiency causes a marked reduction in major mature peripheral B cell subsets, particularly marginal zone (MZ) B cells. We hypothesized that WASp deficiency may also lead to a reduction of regulatory B cells (known as B10 cells) belonging to a novel subset of B cells. And in consideration of the key role of B10 cells play in maintaining peripheral tolerance, we conjectured that a deficit of these cells could contribute to the autoimmunity in patients with Wiskott-Aldrich syndrome (WAS). The effects of WASp deficiency on B10 cells have been reported by only one group, which used an antigen-induced arthritis model. To add more information, we measured the percentage of B10 cells, regulatory T cells (Tregs) and Th1 cells in WASp knockout (WASp KO) mice. We also measured the percentage of B10 cells in patients with WAS by flow cytometry. Importantly, we used the non-induced autoimmune WASp KO mouse model to investigate the association between B10 cell frequency and the Treg/Th1 balance. We found that the percentage of B10 cells was reduced in both mice (steady state and inflammatory state) and in humans and that the lower B10 population correlated with an imbalance in the Treg/Th1 ratio in old WASp KO mice with autoimmune colitis. These findings suggest that WASp plays a crucial role in B10 cell development and that WASp-deficient B10 cells may contribute to autoimmunity in WAS.

Abstract
We report the observation of the X(3823) state in the process e+e-→π+π-X(3823)→π+π-γχc1 with a statistical significance of 6.2σ, in data samples at center-of-mass energies sqrt[s]=4.230, 4.260, 4.360, 4.420, and 4.600 GeV collected with the BESIII detector at the BEPCII electron positron collider. The measured mass of the X(3823) state is (3821.7±1.3±0.7) MeV/c2, where the first error is statistical and the second systematic, and the width is less than 16 MeV at the 90% confidence level. The products of the Born cross sections for e+e-→π+π-X(3823) and the branching ratio B[X(3823)→γχc1,c2] are also measured. These measurements are in good agreement with the assignment of the X(3823) state as the ψ(1 3D2) charmonium state.

Abstract
The double-differential scattering cross-section for the inelastic scattering of x-ray photons from electrons is typically orders of magnitude smaller than that of elastic scattering. With samples 10-100 μm size in a diamond anvil cell at high pressure, the inelastic x-ray scattering signals from samples are obscured by scattering from the cell gasket and diamonds. One major experimental challenge is to measure a clean inelastic signal from the sample in a diamond anvil cell. Among the many strategies for doing this, we have used a focusing polycapillary as a post-sample optic, which allows essentially only scattered photons within its input field of view to be refocused and transmitted to the backscattering energy analyzer of the spectrometer. We describe the modified inelastic x-ray spectrometer and its alignment. With a focused incident beam which matches the sample size and the field of view of polycapillary, at relatively large scattering angles, the polycapillary effectively reduces parasitic scattering from the diamond anvil cell gasket and diamonds. Raw data collected from the helium exciton measured by x-ray inelastic scattering at high pressure using the polycapillary method are compared with those using conventional post-sample slit collimation.

Abstract
The full-length complementary (c)DNA of vacuolar-type-H(+) -ATPase B1 gene (vhab1) in marbled eel Anguilla marmorata with 1741 base pairs (bp) was identified. It contained a 1512 bp open reading frame encoding a polypeptide with 503 amino acids (55·9 kDa), an 83 bp 5'-untranslated region (UTR) and a 146 bp 3'-UTR. The expression levels of A. marmorata vhab1 in gill and kidney of A. marmorata were evaluated at different intervals during the exposure to various salinities (0, 10 and 25). The results indicated that the expression levels of A. marmorata vhab1 messenger (m)RNA in gill and kidney had a significant increase and reached the highest level at 1 h in brackish water (BW, salinity 10) group and 6 h in seawater (SW, salinity 25) group. Therefore, salinity did affect the relative expression level of A. marmorata vhab1 mRNA in gills, which exhibited the enhancement by c. 44 times in SW group when compared with that in fresh water. No remarkable difference in the expression of A. marmorata vhab1 mRNA was observed after 15 days of SW exposure (P > 0·05). V-H(+) -ATPase activity exhibited an increase by two- to three-fold when compared with that in gill and kidney from the control group. The consequence primarily suggested that A. marmorata vhab1 gene product in elvers from A. marmorata plays an important role in adaptation response to SW.

Abstract
The familial acute myeloid leukemia related factor gene (FAMLF) was previously identified from a familial AML subtractive cDNA library and shown to undergo alternative splicing. This study used real-time quantitative PCR to investigate the expression of the FAMLF alternative-splicing transcript consensus sequence (FAMLF-CS) in peripheral blood mononuclear cells (PBMCs) from 119 patients with de novo acute leukemia (AL) and 104 healthy controls, as well as in CD34+ cells from 12 AL patients and 10 healthy donors. A 429-bp fragment from a novel splicing variant of FAMLF was obtained, and a 363-bp consensus sequence was targeted to quantify total FAMLF expression. Kruskal-Wallis, Nemenyi, Spearman's correlation, and Mann-Whitney U-tests were used to analyze the data. FAMLF-CS expression in PBMCs from AL patients and CD34+ cells from AL patients and controls was significantly higher than in control PBMCs (P < 0.0001). Moreover, FAMLF-CS expression in PBMCs from the AML group was positively correlated with red blood cell count (rs =0.317, P=0.006), hemoglobin levels (rs = 0.210, P = 0.049), and percentage of peripheral blood blasts (rs = 0.256, P = 0.027), but inversely correlated with hemoglobin levels in the control group (rs = -0.391, P < 0.0001). AML patients with high CD34+ expression showed significantly higher FAMLF-CS expression than those with low CD34+ expression (P = 0.041). Our results showed that FAMLF is highly expressed in both normal and malignant immature hematopoietic cells, but that expression is lower in normal mature PBMCs.

Abstract
OBJECTIVE Lung cancer is the leading cause of cancer-related death in the world, particularly in major cities in China. We aimed to determine the benefit of survival and toxicity of Conformal Radiotherapy (CRT) combined with erlotinib-based multimodality therapy in newly diagnosed metastatic non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Newly diagnosed metastatic NSCLC patients were treated with CRT and erlotinib, with or without chemotherapy matched protocol. The patients received CRT with a dose of 30-66 Gy. Erlotinib was used at least one 28-day cycle. The primary end point was overall survival (OS). RESULTS Thirty-two patients were analyzed. The median OS was 517 days. Patients with only one metastasis showed longer survival than patients with multi-metastases (986 vs. 380 days, n = 8 vs. 24, p = .009). Patients with multiple metastases in brain conferred worse survival for patients without and with sole brain metastasis (321 vs. 700 days, n=11 vs 21, p = .006). There was no significant difference in median survival whether erlotinib was used as a first-, second- or third-line therapy (380 vs. 700 vs. 310 days, n = 10 vs. 15 vs 7, respectively. p = .179). Patients with TTCRT > 90 days had longer OS than patients with TTCRT ≤ 90 days (749 vs. 322 days, n = 11 vs. 21, p = .012). Patients tolerated treatment with limited Grade 1/2 toxicity. CONCLUSIONS In this study, patients with newly diagnosed metastatic NSCLC had survival benefits when erlotinib was used combined with CRT. Further prospective trials are needed to derive maximal benefit from the drug treatment.

Abstract
Wnts are considered as important factors in uterus developmental process and embryo implantation. Baicalin has been demonstrated to possess tocolytic properties. In order to investigate the effect of baicalin on the Wnt signaling pathway during the peri-implantation, pregnant Kuming mice were randomly divided into four groups: control group, baicalin group administered with 40mg/kg BW of baicalin through an intragastric gavage on day 2 to 7 of the pregnancy (Pd2-Pd7), mifepristone group treated with 4mg/kg BW of mifepristone, an abortifacient agent, via subcutaneous administration on Pd4, and baicalin+mifepristone group treated with their combination. The concentrations of the implantation-related steroid hormones (progesterone and estradiol) in the blood serum were measured with RIA. The gene and protein expression levels of the important molecules of the Wnt pathway (Wnt4, LRP6, Dkk1 and β-catenin) in the endometrium were detected with RT-PCR and western blot, respectively. The results showed that baicalin decreased (P<0.05) the estradiol levels on Pd4-Pd8 and increased (P<0.05) the progesterone levels on Pd3-Pd8. Mifepristone increased (P<0.05) the estradiol levels on Pd5-Pd8 and decreased (P<0.05) the progesterone levels on Pd6-Pd8. Compared with the control group, baicalin increased the gene and protein expression levels of Wnt4, LRP6 and β-catenin (P<0.05) and decreased the gene and protein expression levels of Dkk1 (P<0.05) during the middle-to-late stage of the experiment in mice uterine tissue. Baicalin alleviated the mifepristone-induced increase or decrease in the serum levels of progesterone and estradiol, and the gene or protein expression levels of Wnt4, LRP6 and β-catenin. The tocolytic properties tocolysis of baicalin may be realized through regulating the levels of estrogen/progesterone and the important components of canonical Wnt signaling pathway during the embryo implantation process intervened with the subcutaneous administration of mifepristone in the mice.
