Abstract: This invention relates to a tissue expander for use in medical, veterinary and dental applications. The tissue expander comprises a self-inflating polymer network and a biodegradable polymer having a non-degraded state and a degraded state which in the non-degraded state constrains the inflation of the self-inflating polymer network and in the degraded state allows inflation of the self-inflating polymer network. In a preferred embodiment, the self-inflating polymer network and the biodegradable polymer form an interpenetrating polymer network or a semi-interpenetrating polymer network. Alternatively or in addition, the self-inflating polymer network forms a core and the biodegradable polymer forms coating which partially or fully surrounds the core.

Abstract: A method of preparing a protein chip by gelation of a sol composition. In the method, a mixture of specific silicate monomers, such as SolB1, SolB2 and SolB3, SolBH, and a mixture of SolBS, distilled water and a detector protein are mixed sequentially, so that the gelation rate of the sol composition can be delayed, thus inducing the stable gelation of the composition. Also, the biochip can be fabricated in a simple and easy manner by dispensing the sol composition by hand using an arrayer or a tool such as a pipette. In addition, a uniform biochip can be prepared by dispensing the sol composition, solution I (SolBH) and solution II (a mixture of buffer, SolBS, distilled water and a detector protein) sequentially onto a substrate without needing a conventional pretreatment process such as mixing.

Abstract: The invention provides a multiplexed assay device comprising a reaction chamber and several sets of encoded microcarriers 2 wherein the reaction chamber is a microchannel 1 and wherein the longitudinal movement of the microcarriers 2 is restricted and wherein the microcarriers 2 have a shape in relation to the geometry of the microchannel 1 such that at least two can stand side by side in the microchannel 1 without touching each other and without touching the perimeter of the microchannel 1 and are preferably observable in the reaction chamber. Moreover, the invention provides a method for performing multiplexed assay based on microcarriers 2 that improves mass transfer, simplifies the preparation and the execution of the assay and facilitates readout of biological reactions and identity of microcarriers 2.

Abstract: System, including methods and apparatus, for performing a digital assay with multiplexed detection of two or more distinct targets in the same optical channel.

Abstract: Pap smears and HPV infection tests do not distinguish between lesions that will progress to an invasive carcinoma and those that will not. We aimed to identify epigenetic biomarkers for diagnosis and progression monitoring of premalignant lesions in cervical cancer. Hypermethylated genes were identified as potential biomarkers after validation by MSP, including GGTLA4 and ZNF516. The methylation frequency for these two genes was higher in tumor: GGTLA4 (100%) and ZNF516 (96%); than in normal samples: GGTLA4 (12%) and ZNF516 (16%). The methylation status of GGTLA4 showed a progression in methylation frequency from normal samples to invasive carcinoma. The immunohistochemical expression was lower in tumor for both: GGTLA4 (50.8%) and ZNF516 (66.2%); than in normal samples: GGTLA4 (71.2%) and ZNF516 (88.1%) (p<0.05). In conclusion, we identified methylation biomarkers for the molecular screening and characterization of cervical cancer.

Abstract: The present disclosure relates to detecting receptor-ligand binding by measuring local pH modulation using a pH-sensitive fluorophore.

Abstract: The present invention relates to the detection of a target nucleic acid sequence by a PTOCE (PTO Cleavage and Extension) assay. The present invention detects a target nucleic acid sequence in which the PTO (Probing and Tagging Oligonucleotide) hybridized with the target nucleic acid sequence is cleaved to release a fragment and the fragment is hybridized with the CTO (Capturing and Templating Oligonucleotide) to form an extended duplex, followed by detecting the presence of the extended duplex. The extended duplex provides signals (generation, increase, extinguishment or decrease of signals) from labels indicating the presence of the extended duplex and has adjustable Tm value, which are well adoptable for detection of the presence of the target nucleic acid sequence.

Abstract: Multi-layered optical sensor films are disclosed. The sensor films include a first reflective layer, a detection layer over the reflective layer, and optionally a second reflective layer over the detection layer. The detection layer contains a hydrophobic, amorphous, substantially microporous, analyte-sensitive organosilicate composition. The analyte-sensitive organosilicate composition provides an optical change in the film upon analyte exposure.

Abstract: Methods for producing recombinant cell populations are disclosed. The disclosed methods may be used to produce therapeutic polyclonal proteins.
