PXE国际关于弹性假黄瘤(PXE)的研究团队，对其的病因提出了现有的两种假设：积极的循环代谢产物或者组织特异性功能障碍。任务要求提供数据来求证这两种假设或其中之一。根据各地的发病机制进行实验，进一步了解PXE的病因。 这项任务保证至少会奖励一名挑战者，并且，除了任务奖金之外，PXE国际还将对中标者给予PXE的研究经费资助。 征稿件请直接上传网址：https://www.innocentive.com PXE – Evaluating Hypotheses and Suggesting Experiments for a Rare Disease TAGS: Computer Science/Information Technology, Chemistry, Global Health, Nature, Public Good, Life Sciences, Ideation AWARD: $7,000 USD | DEADLINE: 11/30/12 | ACTIVE SOLVERS: 38 | POSTED: 10/31/12 The Seeker, PXE International, the primary group responsible for funding PXE research, presents two existing hypotheses (an active circulating metabolite(s) or a tissue-specific dysfunction) for the rare disease Pseudoxanthoma Elasticum (PXE). The Seeker requests that Solvers present evidence favoring one of the two hypotheses, then provide additional experiments to conduct to further knowledge around the disease mechanism. This is an Ideation Challenge with a guaranteed award for at least one submitted solution. In addition to the Challenge award, PXE International will also assist finalists in efforts to obtain funding for PXE-related research. Detailed Description & Requirements INTRODUCTION TO PXE Pseudoxanthoma Elasticum (PXE) is a recessive genetic disorder with signs and symptoms that mimic many aspects of the normal aging process, but at a much younger age (when people are roughly between 10 and 20 years old). Specifically, the disease is characterized by fragmentation and mineralization of elastic fibers in certain tissues. Some of the more common symptoms, in general order that they occur, are: Wet-type macular degeneration Skin wrinkling Calcification of blood vessels Cardiovascular disease PXE is a rare disease with an estimated patient population of 12,000 people. Given the small number of people with the disease, it has not been the subject of research by for-profit pharmaceutical and biotech companies.   [更多]

摘要： 这项任务是寻找一种新的配方，合成除虫菊酯缓释制剂。 要求改变其生物活性化合物的挥发，使其的生物活性超过一年。这项配方必须要有足够的稳定性，即使是在热带环境中放几年也不受影响。并且所得的制剂在跟水稀释后能喷洒或涂刷在表面。要求这个配方必须使用常用的材料和国家最先进的制造工艺，并且对人体和环境是安全的。 这项任务需要提交一份详细的书面报告。 具体要求： Sustained Release Formulation for Synthetic Pyrethroids TAGS: Food/Agriculture, Chemistry, Physical Sciences, Theoretical-IP Transfer AWARD: $25,000 USD | DEADLINE: 12/16/12 | ACTIVE SOLVERS: 10 | POSTED: 10/16/12 The Seeker is looking for a novel formulation that modifies the volatility of a biologically active compound to give a product with activity of more than one year. The formulation should be stable for several years of storage even under tropical conditions. The resulting formulation should be able to be applied by spraying or by brushing etc. after dilution with water on many surfaces. The Seeker requires that the formulation technique must use commonly available materials and state of the art manufacturing process, as well as be safe for humans and the environment. This Challenge requires only a written proposal. Sustained Release Formulation for Synthetic Pyrethroids Detailed Description & Requirements INTRODUCTION The Seeker is keenly interested in finding a “new and novel” approach to formulation that will stabilize a volatile synthetic bioactive, for a full year after application via sprayed or brushed-on use scenarios, yet protected from its typical routes of decomposition. The formulation must be considered safe for humans and the environment, and it must be cost-effective to manufacture from commodity-type materials using state-of-the-art manufacturing processes. DETAILS OF COMPOUND TO BE FORMULATED The active the seeker is interested in belongs to the chemical class of synthetic pyrethroids (http://en.wikipedia.org/wiki/Pyrethrin). It has a molecular weight of approx. 400, a vapor pressure of about 1mPa at 25°C, a very poor solubility in water but high in non-polar media. Types of   [更多]
