摘要:
In some aspects, the invention provides a genetically tractable in situ non-human animal model for hepatocellular carcinoma. The model is useful, inter alia, in understanding the molecular mechanisms of liver cancer, in understanding the genetic alterations that lead to chemoresistance or poor prognosis, and in identifying and evaluating new therapies against hepatocellular carcinomas. The liver cancer model of this invention is made by altering hepatocytes to increase oncogene expression, to reduce tumor suppressor gene expression or both and by transplanting the resulting hepatocytes into a recipient non-human animal.The present invention also provides methods for identifying and validating tumor suppressor genes by screening pools of shRNAs that target genomic regions deleted in human cancers, such as human hepatocellular carcinomas. The present invention also provides validated tumor suppressor genes, and methods of inhibiting cell proliferation and/or tumor growth, for example by expression of such tumor suppressor genes.

The invention provides methods for diagnosing cancers in humans by detecting DNA amplifications in chromosomal region 8p22, which encompasses the FGF-20 gene and the EFHA2 gene. Also provided are cancer treatment methods using inhibitors of FGF-20 and EFHA2. The invention also provides methods for promoting successful regeneration of liver function. These methods can be used therapeutically to improve liver function following transplantation in both recipient and donor subjects.

摘要:
A plastic injection molding system includes a mold having an interior surface and an exterior surface. The interior surface defines a mold cavity, which is configured in a shape of a part to be formed. A source of plastic, having a known heat deflection temperature, is injected into the mold cavity. At least one infrared heat source is disposed adjacent the mold. The at least one heat source is moveable between a first position disposed away from the interior surface of the mold and a second position where the at least one heat source is in communication with the mold cavity surface. A controller is in communication with the at least one heat source and is configured to heat the mold cavity surface to a predetermined temperature below the heat deflection temperature of the plastic resin. At least one temperature sensor is in communication with the interior surface of the mold and in communication with the controller to move the at least one heat source to the second position when the interior surface of the mold reaches the predetermined temperature.

摘要:
A mounting for an all-in-one personal computer (10) that has a stand (12) for supporting the computer on a table or desk to enable the computer to be mounted on a wall or at the end of an articulated arm. A bracket (16) has a first wall (16A) that is disposed to confront a face of the stand surrounding the through-hole in the stand and that contains a through-hole (24) that registers with a through-hole (26) in the stand and a second wall (16B) that joins with the first wall and that contains a VESA compliant hole pattern that provides for attachment to a VESA compliant member. A hollow bolt (20) and a nut (22) coact with the registered through-holes to hold the first wall of the bracket fast on the stand.

A cervical traction device includes a base, a cervical force application member, and a motor operably attached to the cervical force application member. The motor preferably drives the cervical application member through a friction drive system in order to provide a force to a person's cervical vertebrae. The friction drive system provides overload protection to prevent application of excessive traction forces to the patient.

摘要:
The present invention provides nucleic acid and protein sequences for a novel potassium channel protein, KCNB. The herein-disclosed sequences can be used for any of a number of purposes, including for the specific detection of KCNB, for the identification of molecules that associate with and/or modulate the activity of KCNB, to diagnose any of a number of conditions associated with KCNB or KCNB activity, or to modulate the number or activity of KCNB molecules in a mammal.
