    • The present technology provides new compositions comprising at least one cross-linked co-polymer. In some embodiments, the polyacrylamide co-polymer comprises water soluble subunits, cross-linking subunits, and iron chelating subunits. In other embodiments, the co-polymer comprises water soluble units, cross-linking subunits, and substituted subunits, which can be conjugated with iron-chelating agents. When these new particles are exposed to certain environments, such the presence of strong acids or oxidation agents, these particles are capable of breaking up so that the iron chelating agents can chelate iron or other metals from their environments. Methods to prepare these new compositions are also provided. These compositions or compositions comprising nanogels of the present technology may be used to treat metal overload conditions such as iron overload resulting from chronic transfusions.
    • 本技术提供了包含至少一种交联共聚物的新组合物。 在一些实施方案中,聚丙烯酰胺共聚物包含水溶性亚基,交联亚基和铁螯合亚基。 在其它实施方案中,共聚物包含可与铁螯合剂缀合的水溶性单元,交联亚单元和取代亚单元。 当这些新的颗粒暴露于某些环境,如强酸或氧化剂的存在时,这些颗粒能够分解,使得铁螯合剂可以从其环境中螯合铁或其它金属。 还提供了制备这些新组合物的方法。 包含本技术的纳米凝胶的这些组合物或组合物可用于治疗由慢性输血引起的金属过载状况,例如铁超载。

    • Fill materials for hydrophobic drugs, such as progesterone, and methods of making and using thereof are described herein. The fill material contains the hydrophobic drug dissolved in one or more fatty acids. The concentration of the hydrophobic drug is typically from about 7% to about 50% by weight of the fill material. The concentration of the one or more fatty acids is from about 60% to about 95% by weight of the carrier. The formulation also contains an organic acid and one or both of one or more pharmaceutically acceptable alcohols and one or more pharmaceutically acceptable mono-, di-, or triesters of medium or long chain fatty acids. The fill material can be encapsulated in a hard or soft capsule. The formulations described herein have a higher dissolution rate and faster onset of dissolution compared to micronized progesterone suspended in an oil and thus should have increased bioavailability in vivo.
    • 本文描述了用于疏水性药物(例如孕酮)的填充材料及其制备和使用方法。 填充材料含有溶解在一种或多种脂肪酸中的疏水性药物。 疏水性药物的浓度通常为填充材料重量的约7%至约50%。 一种或多种脂肪酸的浓度为载体重量的约60%至约95%。 制剂还含有一种有机酸和一种或多种药学上可接受的醇和一种或多种药学上可接受的中,长链脂肪酸的一,二或三酯的一种或两种。 填充材料可以被包封在硬或软胶囊中。 与悬浮在油中的微粉化孕酮相比,本文所述的制剂具有更高的溶解速率和更快的溶解出现,因此应该具有增加的体内生物利用度。

    • Liquid orlistat-containing fill materials suitable for encapsulating in hard or soft capsules are described herein. The fill material contains orlistat dissolved in one or more medium chain triglycerides or medium chain partial triglycerides, one or more citrate esters, and combinations thereof. The fill material can also contain one or more pharmaceutically acceptable excipients. In one embodiment, the fill material is substantially free of surfactants. The fill material can be encapsulated in hard or soft, gelatin or non-gelatin capsules. The capsules may be coated to modify release of orlistat from the capsule. Alternatively, the fill material can be encapsulated in an enteric capsule, wherein the enteric polymer is a component of the capsule shell, rather than a coating over the capsule shell. The fill materials are stable at elevated temperatures over an extended period of time and allow for high loadings of orlistat (e.g., 20% w/w or higher).
    • 本文描述了适用于包封在硬胶囊或软胶囊中的含有液体奥利司他的填充材料。 填充材料含有溶解在一种或多种中链甘油三酯或中链部分甘油三酸酯中的奥利司他,一种或多种柠檬酸酯及其组合。 填充材料还可以含有一种或多种药学上可接受的赋形剂。 在一个实施方案中,填充材料基本上不含表面活性剂。 填充材料可以包封在硬或软的明胶或非明胶胶囊中。 胶囊可以被涂覆以改变从胶囊释放奥利司他。 或者,填充材料可以包封在肠溶胶囊中,其中肠溶性聚合物是胶囊壳的组分,而不是胶囊壳上的涂层。 填充材料在高温下在延长的时间内是稳定的并且允许高负荷的奥利司他(例如,20%w / w或更高)。

    • Described is a method of identifying an immunologically active antigen of a virus that attacks skin, as well as a method of enriching a population of lymphocytes for T lymphocytes that are specific to a virus that attacks skin. Also provided are HSV antigens and epitopes that are useful for the prevention and treatment of HSV infection that have been identified via the methods of the invention. T-cells having specificity for antigens of the invention have demonstrated cytotoxic activity against cells loaded with virally-encoded peptide epitopes, and in many cases, against cells infected with HSV. The identification of immunogenic antigens responsible for T-cell specificity provides improved anti-viral therapeutic and prophylactic strategies. Compositions containing antigens or polynucleotides encoding antigens of the invention provide effectively targeted vaccines for prevention and treatment of HSV infection.
