Resuscitation Using Liposomal Vasopressin in an Animal Model of Uncontrolled Hemorrhagic Shock.

Background: Current research suggests that administration of vasopressin to patients with uncontrolled hemorrhagic shock (UHS) can avoid the detrimental effects associated with aggressive fluid resuscitation. However, vasopressin has a short half-life of 10~35 minutes in in vivo use and precludes its use in the pre-hospital setting. To increase the half-life of vasopressin, we proposed to synthesize liposome-encapsulated vasopressin and test it in a rat model of UHS.

Synergism through combination of chemotherapy and oxidative stress-induced autophagy in A549 lung cancer cells using redox-responsive nanohybrids: a new strategy for cancer therapy.

A combination of various therapeutic approaches has emerged as a promising strategy for cancer treatment. A safe and competent nano-delivery system is thus in urgent demand to facilitate the simultaneous transport of various therapeutic agents to cancer cells and a tumor region to achieve synergistic effect. Gold nanoparticles (GNPs) and mesoporous silica nanoparticle (MSNs) were fabricated herein as potential candidates for drug delivery.

Facile preparation of high-quantum-yield gold nanoclusters: application to probing mercuric ions and biothiols.

This paper describes an eco-friendly, one-pot strategy for the synthesis of water-soluble, high-quantum-yield gold nanoclusters (AuNCs) stabilized with 11-mercaptoundecanoic acid (MUA) on their surfaces. The as-prepared ultrasmall MUA-AuNCs (1.9 nm) exhibited a quantum yield (QY) of 13%, higher than those of most previously described thiol-protected AuNCs.

Monitoring the subcellular localization of doxorubicin in CHO-K1 using MEKC-LIF: liposomal carrier for enhanced drug delivery.

Doxorubicin (DOX) is an extensively used anthracycline that has proven to be effective against a variety of human malignant tumors, such as ovarian or breast cancer. While DOX was administered into cultured cancer cell targets (such as CHO-K1) in either free drug form or in drug carrier-associated form (i.e.

Antioxidant, anti-inflammatory and anti-browning activities of hot water extracts of oriental herbal teas.

Traditionally, antioxidants are used to scavenge reactive oxygen species (ROS), which are harmful by-products of aerobic metabolism. Inulae Flos, Horsetail, Chinese Leucas, Broomweed and Indian Wikstroemia are five herbal teas commonly consumed by Asians. Our aim was to investigate the hot water extracts of these five herbal teas for their total phenolics/flavonoid contents and antioxidant capacities.

Anti-inflammatory effect of spilanthol from Spilanthes acmella on murine macrophage by down-regulating LPS-induced inflammatory mediators.

Spilanthes acmella (Paracress), a common spice, has been administered as a traditional folk medicine for years to cure toothaches, stammering, and stomatitis. Previous studies have demonstrated its diuretic, antibacterial, and anti-inflammatory activities. However, the active compounds contributing to the anti-inflammatory effect have seldom been addressed.

Development of a long-life capillary enzyme bioreactor for the determination of blood glucose.

A long-life capillary enzyme bioreactor was developed that determines glucose concentrations with high sensitivity and better stability than previous systems. The bioreactor was constructed by immobilizing glucose oxidase (GOx) onto the inner surface of a 0.53mm i.
