  • Patent number: 8785493
    Abstract: Activation of HIV-1 replication causes oxidative stress, which in turn potentiates HIV-1 replication. The common basis for the compounds of the present invention is: A) the capacity of reactivating HIV-1 from latency, and B) the ability to counteract the cellular machinery which activates in order to limit the effects of oxidative stress. In this way, oxidative stress can be potentiated and a “chain reaction” is sparked. This “chain reaction” induces a more efficient reactivation of HIV-1 from latency and, in some cases, induces selective killing of the infected cells. Actions A) and B) can either be carried out by one drug exerting both effects, or obtained by the combined use of distinct drugs. There are two main cellular machineries counteracting oxidative stress, i.e. the thioredoxin (Trx) thioredoxin reductase (TrxR) system and glutathione. Herein, we present drug strategies capable of exerting action B) by blocking either of the two machineries.

  • Publication number: 20140170070
    Abstract: In the present invention, a method of producing stable bare colloidal gold nanoparticles is disclosed. The nanoparticles can subsequently be subjected to partial or full surface modification. The method comprises preparation of colloidal gold nanoparticles in a liquid by employing a top-down nanofabrication method using bulk gold as a source material. The surface modification of these nanoparticles is carried out by adding one or multiple types of ligands each containing functional groups which exhibit affinity for gold nanoparticle surfaces to produce the conjugates. Because of the high efficiency and excellent stability of the nanoparticles produced by this method, the fabricated gold nanoparticle conjugates can have surface coverage with functional ligands which can be tuned to be any percent value between 0 and 100%.

    Abstract: Technologies are described herein for styptic compounds comprising a hemostatic or styptic agent suspended within a hydrophobic carrier medium. Example carrier mediums may include waxes, lipids, oils, or combinations thereof. The compound may be a semisolid at room temperature and soft enough to be easily dispensed and formed into or onto bleeding tissue of an animal or human. The hydrophobic qualities of the carrier medium can protect the styptic agent from absorbing moisture. The carrier medium can mechanically support positioning treatments adjacent to the bleeding tissue. The carrier medium can further serve to mechanically seal the tissue to aid in hemostasis while also protecting the tissue from debris and contamination. The carrier medium can aid in maintaining moisture within the tissue. Slurry-based manufacturing processes can support a substantially homogeneous dispersal of styptic agent throughout the carrier medium.

The fibers are keratinous fibers like wool fibers, or polyacrylonitrile (PAN) fibers. The first metal cation is selected from transition metal copper, silver and gold included. A second non-transition metal cation can be present. The catalyst is prepared by first treating the fibers with hydrazine and/or hydroxylamine salt in presence of a base, the modified fibers are then treated with an aqueous solution of containing the metal cations.

  • Publication number: 20130096098
    Abstract: Silver(I) cyanoximates of AgL composition (L=NC—C(NO)—R, where R is electron withdrawing groups: —CN, —C(O)NR2, —C(O)R? (alkyl), —C(O)OEt, 2-heteroaryl fragments such as 2-pyridyl, 2-benzimidazolyl, 2-benzoxazolyl, 2-benzthiazolyl) are synthesized and characterized using spectroscopic methods and X-ray analysis. The synthesized compounds also demonstrate remarkable insensitivity toward visible light and UV-radiation. The combined characteristics of these compounds, such as light insensitivity, poor water solubility, high thermal stability, lack of toxicity of organic ligands, and antimicrobial activity make these silver(I) cyanoximates compounds suitable for use in biomaterial and medical devices.
