VIENNA, AUSTRIA -- October 19, 2007 -- Alcohol-dependent patients who are taking a cognitive inhibition test perform better when they receive the dopamine agonist apomorphine, while healthy controls experience a post-treatment deterioration in performance, researchers reported here at the 20th congress of the European College of Neuropsychiatry.

Histological structures of bursas of Fabricius were observed at the different developmental stages from chicken embryoes to chickens. The results were as follows. The bursa of Fabricius began to develop on the 13th day of post-hatching and its cell aggregated into the nodosity clique underneath the epithelium mucosae. On the 15th day of post-hatching, those cell cliques were surrounded by the flat epithelium and formed the basic structure of folliculus lymphaticus. The number of lymphocytes in the folliculus lymphaticus increased gradually, and the medulla and cortex of a majority of folliculus were not discriminated obviously. Until on the 7th day for chickens, the medulla and cortex of folliculus formed completely and the number of folliculus increased significantly. From 21 to 35 days old, the folliculus lymphaticus transformed from polygon into rectangle. Mucosa epithelial cells increased gradually and their cytoblasts arranged compactly into aline in the basilar part on the 35th day.

本研究观察了从鸡胚到出壳后的不同生长发育阶段法氏囊的组织结构，结果表明：胚胎13日龄时，法氏囊开始发育，粘膜上皮下形成结节状细胞集团；胚胎15日龄，聚集的细胞集团形成初始的淋巴滤泡；胚胎18日龄到出壳后1日龄，滤泡内淋巴细胞数量增多，多数滤泡髓质和皮质界限仍不明显；7日龄雏鸡法氏囊髓质皮质分界清晰，滤泡数量显著增多；21日龄到35日龄，滤泡由多边形逐渐转变成长方形；在35日龄时，粘膜上皮细胞逐渐增多，排列紧密，细胞核紧密排列成直线位于基底部。

After cooking, ketones increase, 3-penten-2-one, 1-penten-3-one and 2-nonanone contributed the good flavor. At the same time, cooking reduced the acids and ringed compounds, which was benifical for the flavor. Although the content of aldehydes didn't change significantly, but the contents of some aldehydes, such as benzaldenyde, heptanal, nonyl aldenhyde lilac aldehyde and 4Z-heptenal, which contributed good flavor to the cooked oyster, increased.Maillard reaction was used to improve the flavor of the flavor product from oyster.

对于生牡蛎，烃类以及1-辛烯-3-醇、4-壬烯醛、2-辛醛等会对风味产生较大的影响；在煮制后的牡蛎中，酮类的数量增加，并大多贡献出美好的风味，其中3-戊烯-2-酮、1-戊烯-3-酮、2-壬酮对煮制牡蛎的风味具有好的作用：煮制会使酸类和带有不良风味的环状化合物的数量减少；醛类的数量和含量在煮制前后虽然没有太大的改变，但是苯甲醛、庚醛、壬醛、丁香醛、4-Z庚烯醛等可以产生良好风味的物质含量增加，贡献了煮制后牡蛎的美好风味。

But recent survey reported that Panicum maximum, a perennial grass in the family of Poaceae and listed as one of the twenty most noxious invasive plants in Taiwan has replaced the role of M sinensis in those areas. As a result of recurrent burning, A. confuse forest has been gradually replaced by the grassland of P. maximum. In this study, I compared morphological, photosynthetic, growth and life history characters of field growing P.

早期的研究指出：在大肚山与铁砧山区的本地植物芒草为当地相思树林反覆火烧后的最优势种；但近年来同一地区的研究显示：大黍已取代芒草的角色，而且发现大黍在火烧后植群覆盖度显著的增加，但芒草却没有相同的现象；反覆火烧使得大肚山地区的相思树林逐渐转变成以大黍为主的草生地。

Methods After fixed by paraformaldehyde, vascular endothelial cells from pigs were co-cultured in vitro with natural killer cells from Chinese monkeys at different ratios. The change of the cytotoxicity of natural killer cells occurring after this contact and the content of IFN-γ and TNF-α in the supernatants were detected.

The noise frequency modulation signal was particularly analyzed. The Fokker-Planck equation of noise frequency modulation was presented and the Motion-Group Fourier Transform was used by converting the partial differential equation into the variable coefficient homogenous linear differential equations. Then the solutions were given by using the peano-baker series. So the probability density function of noise frequency modulation in the filter was given. On the basis of the probability density function the stochastic resonance of noise frequency modulation signal is analyzed.

首先建立了噪声调频干扰信号通过脉冲压缩雷达中频滤波器后所满足的福克尔－普朗克方程，然后利用群移傅立叶变换（Motion-Group Fourier Transform，MGFT）将此偏微分方程化成了变系数齐次线性微分方程组，并利用Peano-Baker级数法给出了该方程组的解，最后得到了噪声调频干扰信号通过脉冲压缩雷达中频滤波器后的概率密度函数，在此基础上研究了噪声调频干扰信号造成的随机共振现象。
