Plasmodesmata (PDs) are cytoplasmic structures that link adjacent cells to form the symplast of a plant. PDs are involved extensively in a plant's life by mediating symplastic transport of a wide range of ions and molecules. Major components of a plasmodesma (PD) include a plasma membrane, a desmotubule, and a cytoplasmic annulus, all of which are readily detectable by electron microscopy. Both the plasma membrane and the desmotubule contain proteinaceous particles, thought to be involved in altering the size of the cytoplasmic annulus. Cytoskeleton elements (actin and myosin) are essential for maintaining the integrity of PDs. Together with these elements, calcium_binding proteins probably play a significant role in regulating PD function. Symplastic transport occurs through the cytoplasmic annulus for the great majority of solutes, while other substances may traverse through the desmotubule internal compartment, the desmotubule shell, or the plasma membrane. The symplast is subdivided into several domains with varying molecular size exclusion limits (ranging from 10 kD). Plasmodesmata can be either primary or secondary; the former are developed during new wall formation and the latter are made in existing walls. The dynamic nature of plasmodesmata is also reflected by their changing frequencies, which, in turn, depend on the developmental and physiological status of the tissue or the entire plant. While diffusion is the major mechanism of symplastic transport, plasmodesmata are selective for certain ions and molecules. Upon viral infection, viral movement proteins interact with PD receptor proteins and, as a result of yet unknown mechanisms, the plasmodesmata are remarkably dilated to allow viral movement proteins and the bound viral genome to enter healthy cells. Some proteins of plant origin are also able to traverse plasmodesmata, presumably in ways similar to viral movement proteins. Some of these plant proteins are probably signal molecules con

综合花序拓扑学、比较形态学、分子系统发育、细胞遗传学等资料,对适应辐射类群穇属(Eleusine Gaertn.)的系统学研究进展进行了述评。穇属系统位置——Eleusiinae亚族成员得到分子系统发育证据的支持。该属具有3种花序类型、7个基因组类型、多倍体均由二倍体杂交起源、C4植物高度适应半湿润-半干旱镶嵌气候等特征。据可靠化石记载和现代地理分布推断,穇属很可能起源于东非,时间是晚中新世,而适应辐射则发生在上新世-中新世间隔。总的来说,分子系统发育、细胞遗传学、古地质、古气候数据的整合研究能够为穇属多倍体起源和谱系多样化历史提供令人信服的证据。

Regimes of continuous and pulsed laser action on high-melting oxide compounds of ZrO2 were found with the aim of obtaining steady coatings on monocrystal silicon on laser ablation.X-ray phase analyses,scanning and atomic-force microscopy reveal that the coatings obtained are of nanocluster structure with the cubic *** this case the nanoclusters reach several hundreds of nanometers in *** assumption was made that on laser ablation of ZrO2 thermostabilization may take place where a minimum of the surface energy is attained just at cubic ordering.

在室温下测量了在空气中灼烧掺杂Ｄｙ２Ｏ３的ＳｒＢ４Ｏ７的发射光谱。观测到了由Ｄｙ３＋到Ｄｙ２＋氧化态的变化。经优化，当在空气中灼烧温度为６５０℃时为产生Ｄｙ２＋的最佳温度。在４５７．９ｎｍ的激发下测出了两个峰位分别位于５５０和６６０ｎｍ的宽发射带。我们认为这两个宽发射带是由Ｄｙ２＋离子由５ｄ态向４ｆ基态能级（５Ｉ８）跃迁产生的。讨论了几个有益于在这种基质中还原Ｄｙ３＋离子的条件。为了实现Ｄｙ３＋离子的还原，我们还在Ａｒ／Ｈ２（４％）气氛中制备了Ｄｙ２Ｏ３掺杂的ＳｒＢ４Ｏ７，比较了这种样品和在空气中所制备的样品的光学特性。本文还对标志ＳｒＢ４Ｏ７还原性和稳定性的ｇ－因子由Ｔｍ２＋的［Ｅ０（Ｔｍ３＋／Ｔｍ２＋＝－２．３Ｖ］推导出时Ｄｙ２＋的［Ｅ０（Ｄｙ３＋／Ｄｙ２＋）＝－２．６Ｖ］，但对这种还原过程的局限性尚未确定。

Ophthalmology in China has developed in three successive phases. From the arrival of Dr. Peter Parker in Canton one hundred years ago until the last two decades, emphasis was laid on the curative phase of ophthalmology. Within the last two decades, earlier efforts in ophthalmic research have been coordinated and some notable research work on ophthalmic problems has been done. Although various problems in ophthalmology have been considered from the public health viewpoint, it is only recently that the preventive phase of oph-

Advances in Bioscience and Biotechnology 2013年第1期4卷 143-146页

作者： Diana C. peterson Department of Biomedical Sciences Iowa State University Ames USA

Rheumatic fever is an auto-immune disease caused by exposure to Streptococcus pyogenes. Over the last 50 years, reports of rheumatic fever within the United States have diminished. The decrease was attributed to the advent of penicillin in the treatment of streptococcus infections. We propose that current diagnostic and treatment methodologies may adversely increase the morbidity rate of rheumatic fever within the United States. Publication rates and interest in rheumatic fever has diminished over the last 30 years. Because of this decline, many physicians are only vaguely aware of the disorder. Additionally, the fear of antibiotic resistance has influenced theCenterofDisease Control to suggest a significant decrease in the use of antibiotics by physicians. Although extremely valid for the future health and well-being of the population, such policies must be examined for each individual case carefully. The American Heart Association prescribes long-term antibiotic prophylaxis as the only current treatment;however literature reviews indicate that such therapy is rarely used. Therefore individuals diagnosed with rheumatic fever are not being treated. Additionally, because many physicians are not routinely testing for streptococcus or early signs of endocarditis, it is likely that cases of rheumatic fever will increase in the future, and many individuals may not be diagnosed until sever damage or morbidity occurs. Physician education and clear revised guidelines are necessary to ensure adequate treatment of individuals with rheumatic fever. Mis-understandings of the disease and how it should be treated by first responders (i.e. primary care providers and pediatricians) are discussed.
