    Abstract: Polyglutamates are well known to be highly biocompatible, biodegradable and multifunctional polymers, which have been already used as building blocks in polymer drug conjugates and polymeric micelles. Those systems have been applied to various medical applications ranging from therapy to molecular imaging. Furthermore a polyglutamic acid (PGA) paclitaxel conjugate has already entered clinical studies (Opaxio™ PGA-PTX conjugate currently in phase III of Clinical trials).In this context, a synthetic pathway to a plethora functional polyglutamates (homopolymers, block-co-polymers, triblocks) with well-defined structure, adjustable molecular weight (Mw) and low dispersity (D=Mw/Mn

    Abstract translation: 聚谷氨酰胺是众所周知的高生物相容性,可生物降解和多功能的聚合物,已经被用作聚合物药物共轭物和聚合胶束中的结构单元。 这些系统已经应用于从治疗到分子成像的各种医疗应用。 此外,聚谷氨酸(PGA)紫杉醇缀合物已经进入临床研究(目前在临床试验的第三阶段中的Opaxio TM PGA-PTX缀合物)。 在这种情况下,应用具有明确结构,具有可调分子量(Mw)和低分散性(D = Mw / Mn <1.2)的过多功能性聚谷氨酸(均聚物,嵌段 - 共聚物,三嵌段) 已开发了N-羧酸酐(NCA)的开环聚合(ROP)。 另外,聚谷氨酸的酸部分可以用4-(4,6-二甲氧基-1,3,5-三嗪-2-基)-4-甲基吗啉(DMTMM)活化,各种功能可以通过“ 聚合改性“,产生一组正交反应性附着面。 反应性部分,例如叠氮化物,马来酰亚胺,硫醇,炔(线性或环状)提供了药物,靶向部分或标记的特异性缀合的机会。 除了引入反应性基团之外,功能化策略也用于PGA降低电荷诱导相互作用的PEG化,因此可以调节血液循环时间等药理学性质。 综上所述,已经开发了各种聚谷氨酸的工具包,可以合成各种聚合物药物共轭物或基于聚合物的成像剂。 所开发的功能性聚合物前体将允许我们将聚合物性能官能化并因此调节到期望的应用。

    Abstract: The invention provides a bio-sensing nanodevice comprising: a stabilized G-protein coupled receptor on a support, a real time receptor-ligand binding detection method, a test composition delivery system and a test composition recognition program. The G-protein coupled receptor can be stabilized using surfactant peptide. The nanodevice provides a greater surface area for better precision and sensitivity to odorant detection. The invention further provides a microfluidic chip containing a stabilized G-protein coupled receptor immobilized on a support, and arranged in at least two dimensional microarray system. The invention also provides a method of delivering odorant comprising the step of manipulating the bubbles in complex microfluidic networks wherein the bubbles travel in a microfluidic channel carrying a variety of gas samples to a precise location on a chip. The invention further provides method of fabricating hOR17-4 olfactory receptor.

    Abstract: Immunogens against human extended-progastrin species comprise (A) a mimetic peptide comprised of (i) the amino acid sequence of a progastrin or a N- and/or C-terminal processed species of a progastrin joined to (ii) a 7 amino-acid spacer coupled to (B) an immunogenic carrier. Illustrative of the mimetic peptide/spacer combination are a 21 amino-acid peptide (SEQ ID NO.: 1) and other, related polypeptides (SEQ ID NOs.: 2-5). Pharmaceutical compositions containing such an immunogen display improved immunological properties, including the induction of effective antibody levels shortly after the administration of an initial course of immunogen. Levels of antibody thus elicited stay elevated for several months and readily elevate to higher levels upon subsequent boosting by a single injection of immunogen.
