摘要:
The present invention relates to low reabsorbing semiconductor nanocrystals having, simultaneously, an emission center core surrounded by at least one absorbing shell capable of absorbing blue or purple light and a protective exterior shell. The emission center core is capable of emitting at least one different wavelength range of light. The low reabsorbing semiconductor nanocrystals demonstrate an absorbance ratio greater than or equal to 10. These low reabsorbing semiconductor nanocrystals can be used in optical applications, some of which can include, for example, light-emitting diodes, solid-state-lighting, solar cells, lasers, and biomedical tags.

It is an object of the present invention that the novel nicotinic receptor antagonists disclosed herein may be used in a broad array of clinical or medicinal facets. For example, it is a contemplated use of the present invention that the novel nicotinic receptor antagonists be used to inhibit the growth cycle of non-small cell lung cancer cells. Without being bound by theory, it is an object of the present invention that the nicotinic receptor antagonists disclosed herein are believed to possess reversible binding properties. Moreover, the compounds of the present invention are selective for 0.7 nAChR. For example, the compounds of the present invention are not believed to bind to 0.4 (32 nAChR neuromuscular receptors. It is also contemplated that the nicotinic receptor antagonists of the present invention will be used as a counter measure to treat exposure, or potential exposure, to a wide array of potential neurotoxins.

A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics. The stent has a plurality of hoop components interconnected by a plurality of flexible connectors. The hoop components are formed as a continuous series of substantially longitudinally or axially oriented radial strut members and alternating substantially circumferentially oriented radial arc members. The geometry of the struts and arcs is such that when the stent is expanded, it has very high strains within a relatively small region. This strain localization results in what is often referred to as “hinging”, where the hinge is the small region within which the strains are very high.

The present invention is a method of shoot apical meristem transformation for monocot plant via sufficient and micro wounding (SMW). The technical process includes: expose the apical meristem by removing the coleoptile away when the shoot grows to 0.2-2 cm after 1-2 days of seed germination; make sufficient and micro wounding transformation to the apical meristem by stabbing and brushing for 2-3 times using the SMW brush having 100-5000 bristles which is 4-20 μm in diameter for each one and 0.5-3 mm in exposed length, and dipped with the Agrobacterium tumefaciens containing binary vector harboring exogenous genes; develop the treated meristems directly to normal plants after co-cultivation; promote the plants to develop big spikes and set more seeds; harvest the seeds of T0 plants separately; detect and identify the transformation results in T1 generation which is bred from each individual T0 plant. The advantages of the invention are independent of tissue culture, unlimited in genotype, unnecessary to carry resistant marker, simple and large scale to perform, and applicable to all monocot plants which can set seeds. The transformation efficiencies for wheat, rice and maize using this method are 49%, 66.3%, and 100%, respectively.

Methods and arrangements (600) in a first network node (120-1) for managing handover of a user equipment (110) from the first network node (120-1), to a second network node (120-2). The method and arrangement (600) comprises transmitting (501) a handover message to the user equipment (110), which handover message is triggering the user equipment (110) to perform the handover, and to establishing (502) a limit related to the amount of retransmissions to be made. Further the method and arrangement (600) comprises interrupting (503) scheduling of resources to the user equipment (110) and inhibiting further retransmissions of the handover message, when either the established limit is reached, or an indication that the user equipment (110) has left the first cell (130-1) is received. Also, methods and arrangements (800) in a in a second network node (120-2) are disclosed.

Disclosed herein are mesocapsules that include agriculturally active ingredients. These mesocapsules are comprised of a polyurea shell and include hydrophilic groups on their surfaces and have a volume-average diameter of about 500 nm or less and some of them have a volume-average diameter on the order of about 300 nm or less. These mesocapsules are suited for delivering active ingredients that are not very soluble in water. Methods for making these mesocapsules include interfacial polycondensation reactions carried out in the presence of surfactants and other methods in which all or most of the surfactant is replaced by adding amino acids to the aqueous phase of the interfacial reaction mixture before forming the final emulsion.
