Abstract:
A hexacene derivative is described, being expressed by formula (1): wherein X1-X6 denote the presence or absence of a carbonyl bridge [—C(═O)—], with a proviso that at least one of X1-X6 is a carbonyl bridge while any six-member ring absent of a carbonyl bridge is aromatic. A method for forming hexacene is also described, including: thermally treating the hexacene derivative to expel volatile units of CO from the hexacene derivative.
Abstract:
The present invention provides novel compounds of Formula (I), and pharmaceutically compositions thereof. Compounds of Formula (I) are inhibitors of histone deacetylases (HDACs) and 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase (HMGR). Also provided are methods of using the compounds and pharmaceutical compositions for inhibiting the activity of HDACs and HMGR, treating diseases associated with HDACs or HMGR (e.g., cancer, hypercholesterolemia, an acute or chronic inflammatory disease, autoimmune disease, allergic disease, pathogen infection, neurodegenerative disease, and a disease associated with oxidative stress), or inhibiting drug resistance of cancer cells.
Abstract:
Methods for the treatment of a disorder characterized by excessive proliferation and/or lipid content of sebocytes are disclosed. In one embodiment of the invention, the method comprises administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition comprising a small molecule inhibitor targeted to galectin-12 or a nucleic acid-based inhibitor targeted to galectin-12 and a pharmaceutically acceptable carrier, wherein said inhibitor is a non-naturally occurring molecule and administration of said inhibitor produces a decrease in the proliferation and/or lipid content of the sebocytes. Methods for decreasing sebaceous gland size, inhibiting sebocyte proliferation, and/or inhibiting sebocyte lipid content are also disclosed.
Abstract:
This invention relates to an iron-sulfur complex that is capable of efficiently catalyzing formation of hydrogen, and a method for producing hydrogen using the complex as a catalyst. The iron-sulfur complex provided herein comprises: a structure of formula (I) wherein the ligands L1 to L3, L5 and L6 and the groups X1 to X3 are each selected from the group consisting of alkyl, alkenyl, alkynyl and aryl that are substituted or unsubstituted, hydroxyl, carbonyl, aldehyde, and so on; L4 is a bridging ligand selected from the group consisting of hydroxyl, carbonyl, and so on; and the symbol “z” means the charge, which is an integer with the range of −3 to +2. X1 and X2 may join together to form a bridging group between the two sulfur atoms. X3 may alternatively be a vacant site.
Abstract:
The disclosure provides a new use of adenosine analogs for the treatment of pain through activation of neurokinin 1 (NK1) receptor signaling pathway, thereby inducing the activation of M-type potassium channel to induce outward currents. A method and pharmaceutical composition for treating pain comprising an adenonsine analog that activates NK1 receptor signaling, thereby inducing outward current are also provided.
Abstract:
The present invention relates to a transgenic plant overexpressing an antioxidant protein 1 (ATX1)-like polypeptide, which exhibits resistance to excess or deficiency of copper. The present invention also relates to a method of phytoremediation of an environment contaminated with copper by growing a transgenic plant overexpressing an ATX1-like polypeptide in the environment.
Abstract:
Dynamic adaption of transmission rate for multiuser MIMO networks is disclosed. The invention controls a first communication device to transmit data at rates optimal determined under the condition that the channel is occupied by the first communication device, a second communication device to transmit data at rates optimal determined under the condition that the channel is shared by the first and second communication devices and a third communication to transmit data at rates optimal determined under the condition that the channel is shared by the first, second and third communication device.
Abstract:
The present invention provides a method for changing nitrogen utilization efficiency in a plant comprises regulating the expression of Arabidopsis NRT 1.7 or an orthologue thereof so that the nitrate remobilization from older leaves to young leaves in the plant is regulated, thereby the nitrogen utilization efficiency is changed. The present invention also provides a transgenic plant obtainable by transforming a plant with an expression construct with a high or low level of expression of NRT 1.7. On the other hand, the present invention yet provides a chimera nitrate transporter, a DNA molecule coding for this chimera transporter and an expression vector thereof.
Abstract:
The present invention relates to a microfluidic array platform comprising a substrate and two layers between which one membrane is sandwiched, wherein a plurality of cell culture wells are constructed in the top layer and one or more microfluidic channels for oxygen scavenging reactions or/and oxygen generating reactions to control the oxygen tensions are constructed in the bottom player. The microfluidic array platform is capable of simultaneously performing cell culture under different oxygen tensions and compatible with existing cell incubators and high-throughput instruments for cost-effective setup and straightforward operation.
Abstract:
A device for optical mapping of protein binding sites, in particular, transcription factor binding sites, on single DNA molecules, includes an insulating substrate having two parallel channels and at least one slit connecting the two channels, a coverslip on the substrate, at least two reservoirs on the substrate connecting the channels of the insulating substrate, and at least two electrodes in the reservoirs. When the reservoirs are filled with a buffer solution, the electrodes are in electrical contact in the buffer solution.
