    • A diagnostic assay for detecting the presence of an infectious herpesvirus in a specimen and a genetically engineered cell line for use in such assay are disclosed. The cell line used in the assay expresses a reporter gene only if infectious herpesvirus is present in the specimen. The assay involves inoculating a DNA-transfected cell line with a specimen suspected of containing a herpesvirus, allowing a sufficient period of time for the herpesvirus infectious cycle to proceed, and detecting and quantifying the number of herpesvirus-infected cells to determine the number of infectious herpesvirus virions in the specimen. The cell line is a DNA-transfected cell line susceptible to infection by a herpesvirus which is stably transformed with a chimeric gene comprising a herpesvirus inducible promoter and a gene coding for an enzyme, the expression of the enzyme being dependent upon and quantitatively proportional to the presence of herpesvirus. A kit for such assay is also provided.
    • 公开了用于检测样本中的感染性疱疹病毒的存在的诊断测定法和用于这种测定的基因工程细胞系。 只有感染性疱疹病毒存在于样本中时,测定中使用的细胞系才能表达报告基因。 该测定包括用疑似含有疱疹病毒的标本接种DNA转染的细胞系,允许疱疹病毒感染循环的足够的时间进行,并检测和定量疱疹病毒感染细胞的数量以确定感染的数量 样本中的疱疹病毒病毒粒子。 细胞系是由疱疹病毒感染易感染的DNA转染的细胞系,其用包含疱疹病毒诱导型启动子和编码酶的基因的嵌合基因稳定转化,所述酶的表达依赖于和与其成比例 存在疱疹病毒。 还提供了用于这种测定的试剂盒。

    • Single-chain forms of the glycoprotein hormone quartet, at least some members of which are found in most vertebrates, are disclosed. In one embodiment of these single-chain forms, the alpha and beta subunits of the wild-type heterodimers or their variants are covalently linked, optionally through a linker moiety. A drug may further be included within the linker moiety to be targeted to receptors for these hormones. Some of the single-chain forms are agonists and others antagonists of the glycoprotein hormone activity. Another embodiment of the single-chain compounds of the invention comprises two beta subunits of the glycoprotein hormones, which beta subunits are the same or different. These "two- beta " forms are antagonists of glycoprotein hormone activity.
    • 公开了在大多数脊椎动物中发现的至少一些成员的糖链蛋白激素四重奏的单链形式。 在这些单链形式的一个实施方案中,野生型异二聚体或其变体的α和β亚基任选地通过连接体部分共价连接。 接头部分中还可以包含药物以靶向这些激素的受体。 一些单链形式是激动剂和糖蛋白激素活性的其它拮抗剂。 本发明的单链化合物的另一个实施方案包含糖蛋白激素的两个β亚基,β亚单位是相同或不同的。 这些“双β”形式是糖蛋白激素活性的拮抗剂。

    • The present invention provides a noninvasive method for improving collateral circulation to tissue at risk of ischemia or ischemic necrosis. Improved collateral circulation is obtained by applying a growth factor from the PDGF family to the area at or around an occluded blood vessel causing compromised direct circulation to the affected tissue. The present invention further provides a method for anastomosing one or more divided blood vessels using a growth factor from the PDGF family. Preferably, the growth factor is administered locally to the end(s) of the divided blood vessel(s) at or around the area where a single divided blood vessel is attached to tissue of an organ at risk of ischemia.
    • 本发明提供了一种用于改善患有局部缺血或缺血性坏死风险的组织的侧支循环的非侵入性方法。 通过将来自PDGF家族的生长因子应用于闭塞血管周围或周围的区域获得改善的侧支循环,从而导致受影响组织的直接循环受损。 本发明还提供了使用来自PDGF家族的生长因子来吻合一个或多个分开的血管的方法。 优选地,将生长因子局部施用于分开的血管的端部或周围,其中单个分开的血管附着到具有局部缺血风险的器官的组织。
