Title: Histone deacetylase inhibitors
Inventor: LAN-HARGEST HSUAN-YIN
IPC: C07D307/54
Filed: 2002-03-25
Granted: 2012-09-25
Abstract: Histone deacetylase is a metallo-enzyme with zinc at the active site.  Compounds having a zinc-binding moiety, such as, for example, a hydroxamic acid group or a carboxylic acid group, can inhibit histone deacetylase.  Histone deacetylase inhibition can repress gene expression, including expression of genes related to tumor suppression. Accordingly, inhibition of histone deacetylase can provide an alternate route for treating cancer, hematological disorders, e.g., hemoglobinopathies, and genetic related metabolic disorders, e.g., cystic fibrosis and adrenoleukodystrophy.

Filed: 2004-03-09
Granted: 2012-07-10
Abstract: An apparatus and method for inserting rebar bolts during mining ground or roof support operations is disclosed. The apparatus is removeably secured to the front head of an extendable stoper drill. The apparatus has a clutch assembly, comprising a roller, slide plate and an opposing backing plate. The axis of the roller is free to move along the slide plate at an oblique angle away from the pinch arm in the direction of extension. Extension of the drill causes the roller to apply pressure on a rebar bolt held between the slide plate and the backing plate locking it in place until the drill is retracted. When the drill is retracted, the roller moves away from the backing plate, releasing the pressure, and permitting the apparatus to slide down relative to the rebar bolt to grip the rebar bolt at a lower point. When the drill leg is next extended, the rebar bolt can be further driven into the hole penetrating the column of resin. The rebar bolt may be inserted using only the apparatus and the drill. The drill can be used in a normal fashion to drill holes, to spin the rebar bolt and to tension the rebar bolt with the apparatus mounted thereon.

Granted: 2013-06-18
Abstract: The present invention relates to systems and methods that mitigate the intrusiveness of communications between message senders and receivers while facilitating more courteous, seamless, and timely interactions. In one aspect, instant messaging and other forms of communications, such as push-to-talk voice communications, can be improved via employment of time-bounded policies and parameters. When-Free communications allows users to send When-Free messages, that act as near-instant messages that wait until a user or recipient is not in one of a list of states defined as busy or unavailable states. A sender can encode, with a quick gesture or via a standing profile, how long a message is to remain alive before being erased or retracted, or shifted to another communication modality. When-Free variants enable recipients to define policies for handling messages if unavailability persists beyond some time threshold, including the generation of automated responses and the shifting of instant messages to email communications, by moving the conversational thread to an email inbox for later review and response via email or to launch an instant message session that continues where the communication left off.

Abstract: Methods for forming a portion of a wellbore are provided. The well is drilled from a first selected depth to a second selected depth to form a bore through a surrounding earth formation. A fluid heating apparatus is disposed within the bore on a working string. Fluid is then heated by moving the fluid through the fluid heating apparatus in the wellbore. The process of circulating fluid adjacent the earth formation serves to also heat the surrounding formation so as to increase the fracture gradient. The fluid heating process may be conducted during a drilling procedure. Alternatively, the fluid heating process may be conducted in connection with a liner hanging and cementing process. A fluid flow restrictor is provided along a run-in assembly that serves to warm the fluids as they are circulated. The warm fluids provide convective heat to the surrounding earth formation, thereby reducing the formation's fracture gradient.
