摘要:
The present invention provides a process for preparing a modified lipid of the formula comprising reacting (I) a compound of the formula; and (ii) a compound of the formula wherein component (ii) is formulated as a liposome; wherein B is a lipid; wherein A is a moiety of interest (MOI) and is a hydrocarbyl group; wherein X is an optional linker group; wherein R1 is H or a hydrocarbyl group; and wherein R2 is a lone pair, H or a hydrocarbyl group. The moiety of interest A may be selected from a carbohydrate moiety, a polymer, a peptide, a glycoprotein, a small biomolecule (such as a folic acid derivative) and a bioconjugate linker.
摘要:
The present invention provides a delivery vehicle for a therapeutic agent comprising a modified lipid and a therapeutic agent; wherein the modified lipid comprises a lipid and a delivery, targeting or stabilising moiety (DTS moiety); wherein the lipid is linked to the DTS moiety via a linker which is stable in biological fluid and which is unstable in defined conditions; and wherein the DTS moiety is linked to the lipid alter formation of a complex of lipid and therapeutic agent.

The present invention provides a lipid of the formula (I) R3R4N—[Y]q—(CpH2p)—X-Linker-NR1R2 (I) wherein R3 and R4 are independently selected from H and hydrocarbyl groups; q is an integer selected from 1 to 10; Y represents a group (CnH2n)NR5, wherein (i) when q is 1, n is 2, or (ii) when q is greater than 1, each Y may be the same or different and each n is an integer independently selected from 1 to 10, with the proviso that for at least one unit Y, n is 2, and (iii) each R5 is independently selected from H and hydrocarbyl groups; p is an integer selected from 1 to 10; X is an optional group selected from —NR7—, —C(═O)—NR8—, —NR9—C(═O)—, —C(═O)—, —O—, and NR10—C(=0)0-, wherein each R7, R8, R9 and R10 is independently selected from H and hydrocarbyl groups, Linker is an optional group selected from amino acid residues, peptide residues and groups of the formula —(OCH2CH2)1-10, —NR6-(CvH2v)—C(═O)—, wherein R6 is H or a hydrocarbyl group and v is an integer selected from 1 to 11, and —C(=0)-(CH2)0-10—CH2—C(=0)-; R1 is selected from acyclic groups having from 4 to 30 carbon atoms; and R2 is selected from H and acyclic groups having from 4 to 30 carbon atoms. Said lipids can be used in a delivery vehicle (e.g. micelle or liposome) for the delivery of one or more (therapeutic or diagnostic) agents.
摘要:
The system and method described herein may identify one or more virtual desktop extensions available in a cloud computing environment and launch virtual machine instances to host the available virtual desktop extensions in the cloud. For example, a virtual desktop extension manager may receive a virtual desktop extension request from a client desktop and determine whether authentication credentials for the client desktop indicate that the client desktop has access to the requested virtual desktop extension. In response to authenticating the client desktop, the virtual desktop extension manager may then launch a virtual machine instance to host the virtual desktop extension in the cloud and provide the client desktop with information for locally controlling the virtual desktop extension remotely hosted in the cloud.
摘要:
An ultra low frequency transmission system can provide communications, for example, messages, to an individual or a group in areas of a building where conventional transmission reception is limited. A communication system for a structure includes a transmitter and an antenna network extending substantially throughout the structure. The antenna network includes a first portion and a second portion. At least one location in the structure can receive a transmission from the first portion and the second portion of the antenna network. The antenna network is configured to receive the transmission from the transmitter and to communicate the transmission throughout the antenna network to at least one receiver configured to receive the transmission from the transmitter via the antenna network. The antenna network transmits the transmission using an ultra low frequency to the at least one receiver.

The system and method for determining fuzzy cause and effect relationships in an intelligent workload management system described herein may combine potential causes and effects captured from various different sources associated with an information technology infrastructure with substantially instantaneous feedback mechanisms and other knowledge sources. As such, fuzzy correlation logic may then be applied to the combined information to determine potential cause and effect relationships and thereby diagnose problems and otherwise manage interactions that occur in the infrastructure. For example, information describing potential causes and potential effects associated with an operational state of the infrastructure may be captured and combined, and any patterns among the information that describes the multiple potential causes and effects may then be identified. As such, fuzzy logic may the be applied to any such patterns to determine possible relationships among the potential causes and the potential effects associated with the infrastructure operational state.

The system and method for controlling cloud and virtualized data centers described herein may include a computing environment having a model-driven, service-oriented architecture for creating collaborative threads to manage workloads, and further to creating cloud images having embedded management agents and identity services for validating the cloud images prior to deployment into the cloud and virtualized data centers and controlling, monitoring, and auditing activity associated with the cloud images following deployment into the cloud and virtualized data centers.
摘要:
Ultra low frequency transmissions can be used to penetrate obstructions to areas where other operation of other communication devices may be limited, such as in a mine, tunnel, or other underground location. A portable device that includes a supercapacitor, a transmitter, and an antenna can be used to communicate using ultra low frequency transmissions. In one aspect, a communication device comprises a supercapacitor; a transmitter powered by the supercapacitor; and an antenna connected to the transmitter for sending messages. In another aspect, a method for communicating comprises the steps of receiving a message to be transmitted, powering a transmitter from a charged supercapacitor, and transmitting the message via an antenna.
