Curcumin-conjugated gold clusters (CUR-AuNCs) were synthesized using a "green" procedure and utilized as an anticancer and a bioimaging agent. Curcumin is a well-known anticancer agent, which forms a cluster when reacting with a gold precursor under mild alkali condition. A fluorescence spectroscopy analysis showed that the CUR-AuNCs emitted red fluorescence (650 nm) upon visible light (550) irradiation. Fourier transform infrared spectroscopy analysis confirmed the stretching and bending nature between the gold atoms and curcumin...

Palladium, a near-infrared plasmonic material has been recognized for its use in photothermal therapy as an alternative to gold nanomaterials. However, its potential application has not been explored well in biomedical applications. In the present study, palladium nanoparticles were synthesized and the surface of the particles was successfully modified with chitosan oligosaccharide (COS), which improved the biocompatibility of the particles. More importantly, the particles were functionalized with RGD peptide, which improves particle accumulation in MDA-MB-231 breast cancer cells and results in enhanced photothermal therapeutic effects under an 808-nm laser...

Hyperhidrosis o`ccurs when the body produces sweat beyond what is essential to maintain thermal homeostasis. The condition tends to occur in areas marked by high-eccrine density such as the axillae, palms, and soles and less commonly in the craniofacial area. The current standard of care is topical aluminum chloride hexahydrate antiperspirant (10-20%), but other treatments such as anticholinergics, clonidine, propranolol, antiadrenergics, injections with attenuated botulinum toxin, microwave technology, and surgery have been therapeutically implicated as well...

Chemotherapy resistance remains a major hurdle for cancer therapy in clinic due to poor cellular uptake, insufficient intracellular release of drugs. Herein, an intelligent, multifunctional MoS2 nanotheranostic (MoS2-PEI-HA) ingeniously decorating with biodegradable hyaluronic acid (HA) assisted by polyethyleneimine (PEI) is reported to combat drug-resistant breast cancer (MCF-7-ADR) after loading with chemotherapy drug doxorubicin (DOX). The HA can not only target CD44-overexpressing MCF-7-ADR, but also be degraded by hyaluronidase (HAase) that is concentrated in the tumor microenvironment and thus to accelerate doxorubicin (DOX) release...

The combination of W18O49 and TPZ core has been first introduced into the preparation of PEG-PCL (PL) surrounded nanoparticles (NPs). The aim of using W18O49 is employing its capability of reacting with the absorbed O2 to generate reactive oxygen species (ROS) when exposed to a long wavelength laser at 808 nm to increase skin penetration and body tolerance. In this work, we have demonstrated that W18O49 unit gives rise to more hypoxic tumor microenvironment and activate the prodrug TPZ to achieve hypoxia-activated chemotherapy, which could be monitored by the intracellular ROS/hypoxia detection and in vivo PET imaging...

Gradients of hypoxia occur in most solid tumors and cells found in hypoxic regions are associated with the most aggressive and therapy-resistant fractions of the tumor. Despite the ubiquity and importance of hypoxia responses, little is known about the variation in the global transcriptional response to hypoxia in melanoma. Using microarray technology, whole genome gene expression profiling was first performed on established melanoma cell lines. From gene set enrichment analyses, we derived a robust 35 probes signature (hypomel for HYPOxia MELanoma) associated with hypoxia-response pathways, including 26 genes up regulated, and 9 genes down regulated...
