L. Yeh et C. S. Leou, from Lanyu of Taiwan is described and illustrated. It is characterized by the column which is adorned with 1-3 anthers, I.e. additional 2 or 1 stamens often present on the ventral side of column and in the lip which is much shorter (4.5-5.5 mm long) and only saccate at base, not long spurred. Results of a preliminary observation on the variation of anther number, and on the development of fruits have also been noted. We also provide a new key to the species of Erythrodes in Taiwan

Two-dimensional matrix algorithm using detrended fluctuation analysis to distinguish Burkitt and diffuse large B-cell lymphoma
Full text linkCopyright © 2012 Rong-Guan Yeh et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.A detrended fluctuation analysis (DFA) method is applied to image analysis. The 2-dimensional (2D) DFA algorithms is proposed
for recharacterizing images of lymph sections. Due to Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL), there
is a significant different 5-year survival rates after multiagent chemotherapy. Therefore, distinguishing the difference between BL
and DLBCL is very important. In this study, eighteen BL images were classified as group A, which have one to five cytogenetic
changes. Ten BL images were classified as group B, which have more than five cytogenetic changes. Both groups A and B BLs are
aggressive lymphomas, which grow very fast and require more intensive chemotherapy. Finally, ten DLBCL images were classified
as group C. The short-term correlation exponent α1 values of DFA of groups A, B, and C were 0.370 ± 0.033, 0.382 ± 0.022, and
0.435 ± 0.053, respectively. It was found that α1 value of BL image was significantly lower (P < 0.05) than DLBCL. However, there
is no difference between the groups A and B BLs. Hence, it can be concluded that α1 value based on DFA statistics concept can
clearly distinguish BL and DLBCL image.National Science Council (NSC) of Taiwan the Center for Dynamical Biomarkers and

Regulation of neutrophil-mediated killing of Staphylococcus aureus and chemotaxis by c-jun NH2 terminal kinase
No full textThe role of JNK in neutrophil chemotaxis and killing of microbial pathogens remains unclear. Using a recently described cell-permeable peptide inhibitor of the JNK pathway, based on the JBD of JIP-1, coupled to the protein transduction domain of HIV-TAT (TAT-JIP), in association with control peptides, we demonstrate that the JNK pathway plays a major role in regulating human neutrophil chemotaxis and killing of microbial pathogens. Serum-opsonized Staphylococcus aureus elicited JNK activation and c-jun phosphorylation. The activation of the JNK pathway and bactericidal activity were inhibited by the TAT-JIP peptide. The stimulation of oxygen radical generation by S. aureus was dependent on the JNK signaling pathway, as was the phagocytosis of serum-opsonized bacteria. Chemotaxis to activated serum complement but not random migration was inhibited by the TAT-JIP peptide. The findings demonstrate a major role for the JNK signaling pathway in neutrophil-mediated defense against microbial pathogens.Mei-Chun Yeh, Violet Mukaro, Charles S. Hii and Antonio Ferrant

No full textAn analytic Yeh-Feynman-Fourier transform and convolution
No full textLet C\sb0\lbrack0,T\rbrack denote Wiener space. Brue introduced the idea of an L\sp1 analytic Feynman-Fourier transform of functionals on C\sb0\lbrack0,T\rbrack in 1971. Since then many people including Cameron, Johnson, Martin, Skoug and Storvick have extended this theory to L\sp{p} with 1 p 2 for many classes of functionals. Recently, there has also been interest in convolution of functionals on C\sb0\lbrack0,T\rbrack and its relationship to the analytic Feynman-Fourier Transform. Let Q = (0,b) and let C\sb2\lbrack Q\rbrack = \{x(s,t): x is real valued, continuous on Q and x(0,t) = x(s,0) = 0. Yeh developed a measure m on this space and hence we will call C\sb2\lbrack Q\rbrack together with m, Yeh-Wiener Space. In this dissertation we will create an L\sp{p} analytic Yeh-Feynman-Fourier transform of functionals on C\sb2\lbrack Q\rbrack. Also a convolution product will be introduced for functionals on C\sb2\lbrack Q\rbrack. We then show that this transform and convolution product have many of the same properties as the Fourier transform of functions on \Re\sp{n}. That is, we show the inverse transform of the transform of a functional is the original functional. Also we show that the transform of the convolution equals the product of the transforms. Finally, we consider an identity similar to the Plancherel identity. In chapter one we give the basic definitions of Yeh-Wiener space, the analytic Yeh-Feynman-Fourier transform and convolution product. We then consider three classes of functionals on C\sb2\lbrack Q\rbrack. In chapter two we consider functionals of the form F(x) = f(x(s\sb1,t\sb1),x(s\sb1,t\sb2),\...,x(s\sb{m},t\sb{n})). Next, in chapter three we consider functionals of the form F(x) = \int\sb{Q}\int f(s,t,x(s,t)ds dt. Finally we consider functionals of the form F(x) = f(\int\int\sb{Q}\alpha\sb1dx(s,t),\...,\int \int \alpha\sb{n}dx(s,t)) in chapter four. We then close our work by giving a number of specific examples of the transform and its properties in chapter five
