摘要： A method for detection and localization of tissues having estrogen receptors during surgery is disclosed. The method involves administering an effective amount of an estradiol derivative labeled with a radionuclide to a patient and then delaying surgery for a time interval for permitting the labeled estradiol derivative to localize in the tissue. Thereafter, an operative field of the animal is surgically accessed an the tissue within the operative filed examined with a probe to detect photon emission from the labeled estradiol derivative.

摘要： A process for preparing an allylic or an aromatic aldehyde, such as acrolein or benzaldehyde, the process comprising contacting in a basic, liquid, biphasic mixture and at reactive conditions an allylic halide or a halomethylated aromatic, such as allyl or benzyl chloride, with a divalent chromate ion, is improved by contacting the allylic halide or halomethylated aromatic with the divalent chromate ion in the presence of a catalytic amount of a quaternary ammonium and/or phosphonium salt, such as tetra-n-butylammonium chloride. The improved process is faster, cleaner and more complete than the process of the prior art.

摘要： A network firewall security apparatus that enables a very high degree of traffic selectability yet avoids the usual performance penalty associated with firewalls. This approach is specific to high-speed circuit switched networks, Asynchronous Transfer Mode (ATM) networks in particular. Security management is achieved through active connection management with authentication, better suited to the cell-based environment of high-speed circuit switched networks and to the mix of circuit switched traffic, where Internet Protocol (IP) datagrams comprise a fraction of the total traffic. The information in the signaling cells is used to determine which flows, rather than which individual cells, are allowed to pass through the firewall. A hierarchical method has been devised, in which the physical location of the interrelated components may be decoupled. Active connection management is applied in determining the approval of a connection based on signaling information and network state information. Once a flow has been validated, the cells associated with that flow are allowed to proceed through the firewall at line-speed with limited intervention and no performance degradation.
摘要翻译：一种能够实现非常高流量可选性的网络防火墙安全设备，避免了与防火墙相关的常见性能损失。这种方法特别针对高速电路交换网络，特别是异步传输模式（ATM）网络。安全管理通过主动连接管理与认证来实现，更适合于高速电路交换网络的基于小区的环境，以及互联网协议（IP）数据报占总流量的一部分的电路交换业务的混合。信令单元中的信息用于确定允许哪些流通过防火墙，而不是允许哪些单元格通过防火墙。已经设计了一种分层方法，其中相关组件的物理位置可以被去耦合。主动连接管理应用于基于信令信息和网络状态信息确定连接的批准。一旦流程被验证，与该流程相关联的单元格被允许以有限的干预并且没有性能下降，以线速度通过防火墙。

摘要： 1-Aryl-1-hydroxy-2-methylaminopropanes are rearranged from the erythro isomer to the threo isomer by the process of (1) forming the O,N-diacyl derivative of the arylpropanolamine; (2) reacting the product of step (1) with an anhydrous or substantially anhydrous protic acid (thereby forming a novel oxazolinium salt); and (3) reacting the oxazolinium salt from step (2) with an aqueous protic acid. The threo isomer of the arylpropanolamine is thus produced as an amine/acid salt. This salt can be further purified, if desired, by neutralizing the acid/amine salt with caustic isolating the free amine and reprotonating the free base in isopropanol with, for example, anhydrous HCl. This process is particularly applicable to manufacture of d-pseudoephedrine from 1-ephedrine.
摘要翻译：通过（1）形成芳基丙醇胺的O，N-二酰基衍生物的方法将1-芳基-1-羟基-2-甲基氨基丙烷从红异构体重排为苏式异构体; （2）使步骤（1）的产物与无水或基本上无水的质子酸（从而形成新的恶唑啉盐）反应; 和（3）使来自步骤（2）的恶唑啉盐与水性质子酸反应。因此，芳基丙醇胺的苏式异构体以胺/酸盐的形式制备。如果需要，该盐可以通过用分离游离胺的苛性碱中和酸/胺盐进一步纯化，并用例如无水HCl将异丙醇中的游离碱重新分配。该方法特别适用于从1-麻黄素制备d-伪麻黄素。

摘要： Pure 2-(4-isobutylphenyl)propionic acid and related compounds are obtained in good yield by a multi-step process comprising chloromethylation of benzene or an alkylbenzene, conversion of the resulting benzyl chloride to the cyanide, alkylation of that product to the phenylpropionitrile or phenylbutyronitrile, reaction of unreacted benzyl cyanide with an aldehyde to inhibit its hydrolysis, and hydrolysis of the nitrile to the free acid. The products are antiinflammatory, antipyretic, and analgesic drugs.
