摘要:
A latch mechanism assembly includes a cover unit (30), a base unit (50), a latch (60) and an elastic member (70). The cover unit (30) includes a pair of spaced plates (312, 313), and each of the plates (312, 313) defines a hole (315, 316) therein. A latching slot (51) is defined in the base unit (50). The latch (60) is slideably fixed between the plates (312, 313) of the cover unit (30), the latch (60) includes a hook (61) to enter the latching slot (51) to engage in the base unit (50), and a pair of fixing members (65, 66) extends from two ends of the latch (60) to engage in corresponding holes (315, 316) of the plates (312, 313). The elastic member (70) is connected with one fixing member (65) of the latch (60) for restoring the latch (60).
摘要:
The present invention is drawn toward systems, devices, and methods of dermal drug delivery. The system can comprise a gel-triggering agent and a drug-containing composition including a drug and a gelling agent, wherein the drug-containing composition forms a soft, coherent solid when contacted with the gel-triggering agent. A cavity patch is also included having an open cavity configured to be closed at least in part by a skin surface. The open cavity can be further configured to facilitate contact between the skin surface and the gel. The gel-triggering agent and the drug-containing composition can be positioned in the system such that they are kept isolated from one another until immediately before or during use.

The present invention is drawn to systems and methods for treating warts. The system can comprise a wart treatment formulation comprising a substance for treating warts and a cavity patch comprising an open cavity being configured to become a closed cavity upon application and adherence to a skin surface. The closed cavity can be configured to contain the wart treatment formulation.
摘要:
The mechanism by which the high bone mass (HBM) mutation (G171V) of the Wnt coreceptor LRP5 regulates the canonical Wnt signaling was investigated. The mutation was previously shown to reduce Dkk protein-1-mediated antagonism, suggesting that the first YWTD repeat domain where G171 is located may be responsible for Dkk protein-mediated antagonism. However, we found that the third YWTD repeat, but not the first repeat domain, is required for DKK1-mediated antagonism. Instead, we found that the G171V mutation disrupted the interaction of LRP5 with Mesd, a chaperon protein for LRP5/6 that is required for the coreceptors' transport to cell surfaces, resulting in less LRP5 molecules on the cell surface. Although the reduction in the level of cell surface LRP5 molecules led to a reduction in Wnt signaling in a paracrine paradigm, the mutation did not appear to affect the activity of coexpressed Wnt in an autocrine paradigm. Together with the observation that osteoblast cells produce autocrine canonical Wnt, Wnt7b, and that osteocytes produce paracrine Dkk1, we believe that the G171V mutation may cause an increase in Wnt activity in osteoblasts by reducing the number of targets for paracrine Dkk1 to antagonize without affecting the activity of autocrine Wnt.
摘要:
The present invention concerns double-stranded NF-κB decoy oligodeoxynucleotide (NF-κB dsODN) molecules that contain a core sequence capable of specific binding to an NF-κB transcription factor. In a particular aspect, the invention concerns NF-κB decoy molecules that preferentially bind p50/p65 and/or cRel/p50 heterodimers over p50/p50 homodimers. In another aspect, the invention concerns NF-κB decoy molecules with improved binding affinity to p65.
