AIM： To clarify the mechanism underlying the antidiabetic activities of cortex cinnamomi extract （CCE）. METHoDS： To induce in vivo diabetes, mice were injected with streptozotocin （STZ） via a tail vein （100 mg STZ/kg body weight）. To determine the effects of CCE, mice were administered CCE twice daily for 7 d by oral gavage starting 1 wk before the STZ injection. Blood glucose and plasma insulin concentration were measured as an index of diabetes. Also, to induce cytotoxicity of RINm5F cells, we treated with cytokines （IL-1β （2.0 ng/mL） and IFN-γ （100 U/mL））. Cell viability and nitric oxide production were measured colorimetrically. Inducible nitric oxide synthase （iNoS） mRNA and protein expression were determined by RT-PCR and Western blotting, respectively. The activation of NF-κβ was assayed by using gel mobility shift assays of nuclear extracts. RESULTS： Treatment of mice with STZ resulted in hyperglycemia and hypoinsulinemia, which was further evidenced by immunohistochemical staining of islets. However, the diabetogenic effects of STZ were completely prevented when mice were pretreated with CCE. The inhibitory effect of CCE on STZ-induced hyperglycemia was mediated through the suppression of iNoS expression. In rat insulinoma RINm5F cells,CCE completely protected against interleukin-1β and interferon-y-mediated cytotoxicity. Moreover, RINm5F cells incubated with CCE showed significant reductions in interleukin-1β and interferon-y-induced nitric oxide production and in iNoS mRNA and protein expression, and these findings correlated well with in vivo observations. CoNCLUSIoN： The molecular mechanism by which CCE inhibits iNoS gene expression appears to involve the inhibition of NF-κβ activation, These results reveal the possible therapeutic value of CCE for the prevention of diabetes mellitus progression,

The paper includes discussions on the important role of neutron and alpha configurations in proton-rich nuclei in nuclear astrophysics in terms of nucleosynthesis under extremely high-temperature hydrogenburning conditions. The νp-process, which is supposed to take place at the very early epoch of type II supernovae, has considerable neutrons and alphas together with protons. The alpha-induced reactions on proton-rich unstable nuclei in the light mass regions is expected to play a crucial role, but very few of them were investigated well yet because of the experimental difficulties. Specifically, I report our recent experimental effort for the breakout process from the pp-chain region,~7Be(α, γ)^(11)C(α,p)^(14)N under the νp-process. The neutron-induced reactions on proton-rich nuclei, which is even more a challenging subject, were investigated previously for very few nuclei. one possible experimental method is the Trojan Horse Method(THM). We successfully have applied THM to the ^(18)F(n,α)^(14)N reaction study with an unstable beam of ^(18)F.

非抗生素饲料添加剂有助于提高猪的免疫系统,并降低断奶和其他环境应激带来的负面影响。最常用的饲料添加剂包括酸化剂、锌铜、益生菌、直接饲喂微生物、酵母类产品、核苷酸和植物提取物。研究表明添加药理水平的锌铜、特定酸化剂和部分植物提取物可以改善猪的性能或提高其免疫功能。使用益生菌、直接饲喂微生物、酵母类产品、核苷酸也有可能对猪的性能产生有利影响,但因研究结果缺乏一致性,因此仍需进一步研究。

objective: The purpose of this study is to review the clinical experience and performance of noninvasive prenatal testing (NIPT) method, using cell-free DNAto detect chromosomes 21, 18, 13, X, and y abnormalities in over 7910 clinical samples from South Korean population. Method: Pregnant women between 1st of November 2015 to 18th of February 2018, with obstetric clinical findings participated in the study. NIPT was performed based on masivelly parallel sequencing with 0.3× low coverage paired-end sequencing using cell-free DNA in maternal plasma. Further invasive prenatal testing was recommended for pregnant women with positive NIPT results. Results: of the total 7910 participants, 7890 (99.75%) were tested for NIPT and the remaining 20 (0.25%) were below the Quality Control (QC) standards. T13, T18, XXX, XXy and Xyy had 100% of sensitivity, specificity, positive predictive values (PPV) and accuracy. The overall sensitivity was 100% and specificity, PPV and accuracy of all chromosomal abnormalities with further validation were 99.92%, 94.25%, and, 99.92% respectively. Conclusion: our NIPT results showed high positive predictive value for the detection of autosomal trisomies and sex chromosome aneuploidies in our sample cohort.
