    Abstract: Compounds are disclosed for treating AIDS, herpes, and other viral infections by means of lipid derivatives of antiviral agents. The compounds consist of nucleoside analogues having antiviral activity which are linked, commonly through a phosphate group at the 5′ position of the pentose residue, to one of a selected group of lipids. The lipophilic nature of these compounds provide advantages over the use of the nucleoside analogue alone. It also makes it possible to incorporate them into the lamellar structure of liposomes, either alone or combined with similar molecules. In the form of liposomes, these antiviral agents are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target HIV virus. Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins. Effective nucleoside analogues are dideoxynucleosides, azidothymine (AZT), and acyclovir; lipid groups may be glycolipids, sphingolipids, phospholipids or fatty acids. The compounds persist, after intracellular hydrolysis, as phosphorylated or non-phosphorylated antiviral nucleosides. The compounds are effective in improving the efficacy of antiviral nucleoside analogues by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.

    Abstract translation: 公开了通过抗病毒剂的脂质衍生物治疗AIDS，疱疹和其它病毒感染的化合物。 所述化合物由具有抗病毒活性的核苷类似物组成，通常通过戊糖残基的5'位置的磷酸基团连接到所选择的一组脂质之一中。 这些化合物的亲油性质优于单独使用核苷类似物的优点。 它还使得可以将它们单独或与类似分子组合在一起，将它们并入脂质体的层状结构中。 以脂质体的形式，这些抗病毒剂优先被巨噬细胞和单核细胞（已被发现携带目标HIV病毒的细胞）吸收。 可以通过加入配体如单克隆抗体或其它与病毒蛋白结合的肽或蛋白质将其中的位点特异性引入脂质体。 有效的核苷类似物是双脱氧核苷，叠氮胸腺嘧啶（AZT）和阿昔洛韦; 脂质组可以是糖脂，鞘脂，磷脂或脂肪酸。 化合物在细胞内水解后持续存在，作为磷酸化或非磷酸化的抗病毒核苷。 该化合物通过在给药药物结束后延长抗病毒活性，以及​​在用常规形式的抗逆转录病毒药物治疗已经变得耐药的HIV感染中预防逆转录病毒复制，有效地改善了抗病毒核苷类似物的功效。

    Abstract: A single-port memory cell arrangement includes a multiplicity of single-port memory cells, each having a selection transistor and a memory transistor. The selection transistor has a control terminal connected to a word line, and a load-path connected to a data line. The memory transistor has a control terminal connected to a supply potential, and a load-path connected to the second end of the selection-transistor's load-path. The memory transistor is configured to switch, in response to a signal on the data line, between first and second potentials corresponding to two memory states. These potentials and the supply potential are selected such that first and second ends of the memory-transistor-load-path are at the same potential. The memory cell also includes a controllable switch having a first terminal connected to a supply line, and a second terminal connected to the second end of the memory-transistor-load-path. A single charging device assigned to the single-port memory cells provides providing a precharging potential. From time to time, the charging device recharges a selected memory transistor through the supply line and a selected controllable switch corresponding to that memory transistor.

    Abstract: The invention pertains to a layout for a semiconductor memory with multiple memory cells. The layout according to this invention takes into account the “design rules” specified by the manufacturing process or those required by the technology, and attempts to optimize the surface area of the layout of the semiconductor memory. The particular advantage of the invention rests in the fact that for each memory cell, effectively only one contact terminal is needed. In this manner, the required surface area for the semiconductor memory can be reduced significantly. Due to the reduction in the number of contact terminals, the leakage currents can also be reduced.

    Abstract: A controller is disclosed that operates a gas turbine such that a desired reserve power capacity is maintained. The inlet guide vane angle of the compressor is applied as an indicator of the reserve capacity of the gas turbine. The actual inlet guide vane angle is continuously compared to an intended inlet guide vane angle that corresponds to a desired reserve capacity. A controller adjusts the fuel flow to the gas turbine to adjust the turbine output power and thereby maintain the actual inlet guide vane angle at the intended value corresponding to the desired reserve capacity.
