In this study, the genomic structure and regulatory elements of ApoD from 10 representive species including protozoan, invertebrate, protochordate and vertebrate were analyzed and compared. The genomic structure of ApoD is less conserved in organisms from protostome to deuterostome invertebrates, while it is highly conserved among chordates including amphioxus and verebrates. All four conserved cysteine residues are present in amino acid sequence of deuterostome ApoDs, while there are only two cysteine residues in amino acid sequence of protostomes ApoD. Structure divergence between protostome and deuterostome ApoD proteins suggests their function difference. The majority of regulatory elements are present in nearly all organism ApoD genes ranging from unicellular protozoan to mammals, suggesting that ApoD plays a very fundamental role, and possesses a conserved regulatory mechanism. However, there also exist some specific regulatory elements, which are present only in certain species and may perform some special roles.ApoD mRNA expression in murine NIH/3T3 fibroblasts exposed to various stresses such as as hydrogen peroxide and UV light shows dose-dependent increase. And a fly homolog of ApoD, Glial Lazarillo, whose overexpression results in increased resistance to hyperoxia as well as a extension of lifespan under normoxia and resistance to starvation without altering lipid or protein content.

本文首先从生物信息学角度对分属于原生动物、无脊椎动物、头索动物和脊椎动物类群的10种动物ApoD的基因结构及调控区的调控元件进行分析及比较,发现:(1)ApoD基因外显子-内含子结构从原生动物草履虫到原口动物再到后口动物海胆的进化过程中不保守,但在分析的几种脊椎动物中相当保守;(2)文昌鱼ApoD基因扮演从无脊椎动物到脊椎动物承上启下的角色,可能代表了脊椎动物ApoD基因原型;(3)四个半胱氨酸保守位点在后口动物中都存在,而在原口动物中只存在两个,原口、后口动物ApoD蛋白一级结构上的差异反映蛋白功能上可能也存在一定差别;(4)调控区大多数主要调控元件为不同动物共有,说明ApoD主要功能及其表达调控在进化中相当保守;(5)ApoD基因个别调控元件是随着物种进化而出现并开始发挥相关作用,如SF-1;还有一些调控元件在进化过程中还没有发现其规律,这说明ApoD某些功能和基因表达调控模式可能因物种不同而存在一定的差异。

The current antifungal agents used in clinics usually have severe side-effects, it is necessary to seek for new antifungal agents with known or new mechanisms. China has abundant resources in traditional Chinese medicine, therefore exploition of new antifungal agents therefrom is a feasible way.We have screened antifungal activities of 14 ethanolic extracts from traditional Chinese medicines and 21 natural products by using Saccharomyces cerevisiae GL7 and Prototheca wickerhamii as the model microoranganisms. Among the TCMs tested, Cortex Phellodendri, Flos Caryophylli, Fructus Mume, Rhizoma Coptidis and Radix Sophorae tonkinensis showed high antifungal activity. This study layed certain foundation for the development of new antifungal agents.

Four thin-layer drying models were investigated for the description of FIR-assisted freeze-drying characteristics. The models were exponential model, Page model, diffusion model, and approximation of the diffusion model. Tests were conducted using a three-level, three-factor (drying temperature, distance between sample and FIR heater, and sample thickness) design, and quadratic polynomial analyses were performed to relate the drying parameters of thin-layer drying model. The performance of these thin-layer drying models was evaluated by comparing the coefficient of correlation (R2), the sum of squares, and the RMSE amongst four models. Drying parameter K of the Page model gave the best results in describing freeze-drying with FIR of Tylose and sweet potato.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
