We report a simple, fast, and cost-effective approach that measures cancer cell metabolism and their response to anticancer drugs in real time. Using a Light Addressable Potentiometric Sensor integrated with pH sensitive hydrogel nanofibers (NF-LAPS), we detect localized changes in pH of the media as cancer cells consume glucose and release lactate. NF-LAPS shows a sensitivity response of 74 mV/pH for cancer cells. Cancer cells (MDA MB231) showed a response of ∼0.4 unit change in pH compared to virtually no change observed for normal cells (MCF10A)...

CNS Anticancer Drug Discovery and Development November 2016, AZ, USA The 2016 second CNS Anticancer Drug Discovery and Development Conference addressed diverse viewpoints about why new drug discovery/development focused on CNS cancers has been sorely lacking. Despite more than 70,000 individuals in the USA being diagnosed with a primary brain malignancy and 151,669-286,486 suffering from metastatic CNS cancer, in 1999, temozolomide was the last drug approved by the US FDA as an anticancer agent for high-grade gliomas...

With more than 1.6 million new cases of cancer occurring each year, anticancer medications are in high demand. Escalating prescription drug prices have become a significant concern. Anticancer medications are among the most expensive prescription medications, many of them exceeding $100 000 a year. The survival benefits of certain newer anticancer medications may be a few months more than that from the existing treatment but at a much higher price tag. Drug cost may play a substantial role in making treatment choices...

Conjugated polymers are attractive in numerous biological applications because they are flexible, biocompatible, cost-effective, solution-processable, and electronic/ionic conductive. One interesting application is for controllable drug release, and this has been realized previously using organic electronic ion pumps. However, organic electronic ion pumps show high operating voltages and limited transportation efficiency. Here, the first report of low-voltage-controlled molecular release with a novel organic device based on a conjugated polymer poly(3-hexylthiophene) is presented...

Targeting cancer cell-surface receptors is an attractive approach for cancer treatment and diagnosis. Peptides having high binding affinities to receptors overexpressed in cancer cells are useful because of their simple structure, low immunogenicity, and easy, cost-effective chemical synthesis. A number of peptide ligands have been developed for cancer cell-surface receptors and applied to nanoparticles with anticancer drugs, genes, small interfering RNAs (siRNAs), and molecular imaging agents. In particular, recent findings have revealed that peptide-modified PEGylated liposome-encapsulated drugs are effective in cancer-targeted therapy and cancer cell-specific imaging...

Traditional Medicine is widely used in clinical research due to its low toxicity, low number of side effects, and low cost. Many components of common fruits and vegetables play well-documented roles as chemo preventive or chemotherapeutic agents that suppress tumor genesis. The present study was aimed to identify the DPPH (2, 2-diphenyl-1-picrylhydrazyl) free-radical scavenging constituents from methanol extract of Launaea mucronata using bioassay-guided fractionation. The methanolic extract revealed a strong antioxidant activity, the IC50 values (the concentration with scavenging activity of 50%) was 25...

High attrition of new oncology drug candidates in clinical trials is partially caused by the poor predictive capacity of artificial monolayer cell culture assays early in drug discovery. Monolayer assays do not take the natural three-dimensional (3D) microenvironment of cells into account. As a result, false positive compounds often enter clinical trials, leading to high dropout rates and a waste of time and money. Over the past two decades, tissue engineers and cell biologists have developed a broad range of 3D in vitro culturing tools that better represent in vivo cell biology...

The linear-scaling local coupled cluster method DLPNO-CCSD(T) allows calculations on systems containing hundreds of atoms to be performed while reproducing canonical CCSD(T) energies typically with chemical accuracy (<1 kcal/mol). The accuracy of the method is determined by two main truncation thresholds that control the number of electron pairs included in the CCSD iterations and the size of the pair natural orbital virtual space for each electron pair, respectively. While the results of DLPNO-CCSD(T) calculations converge smoothly toward their canonical counterparts as the thresholds are tightened, the improved accuracy is accompanied by a fairly steep increase of the computational cost...

Cancer is a complex and widespread disease, and it is going to be the first cause of death in the world. Chemotherapy has been used to treat cancer, but it is detrimental to immune cells and known to induce numerous side effects. Therefore it is imperative to develop new drugs for the treatment of cancer without any side effects and toxicity. TiO2 nanomaterials are human safe, cost effective, chemically stable and have numerous biomedical applications. Spherical TiO2 fine particles (TFP), TiO2 nanosquares (TNS) and TiO2 nanotubes (TNT) were developed and evaluated for anti-cancer activity in vitro and in vivo...

Spiraling costs of cancer treatments have become a major concern for the payers in the health care system and for individual patients suffering from the cancer drugs' financial toxicity. This article discusses possible solutions from an ethical perspective. First, it gives some orientation about what constitutes a fair price for innovative anticancer agents. While a definitive answer remains difficult, there are good reasons to enter into price negotiations with the pharmaceutical companies to align the price with the R&D costs and the added value of the product...

Non-adherence to medical treatment is prevalent in the context of potentially life-saving treatment for diseases such as cancer. Estimates of non-adherence to oral anti-cancer therapy range between 27% and 63% in studies of cancer patients. This represents a growing challenge, due to the paradigm shift in anti-cancer treatment from parenteral chemotherapy to oral anti-cancer drugs. The importance of adherence to medical treatment is highlighted by the World Health Organization which considers non-adherence to be a major public health concern...

BACKGROUND: Rapid development of novel treatment options demands valid preclinical screening models for urothelial carcinoma (UC). The translational value of high-throughput drug testing using 2-dimensional (2D) cultures is limited while for xenograft models handling efforts and costs often become prohibitive for larger-scale drug testing. Therefore, we investigated to which extent the chicken chorioallantoic membrane (CAM) assay might provide an alternative model to study antineoplastic treatment approaches for UC...

Purpose The low-income subsidy (LIS) substantially lowers out-of-pocket costs for qualifying Medicare Part D beneficiaries who receive orally administered chemotherapy. We examined the association of LIS with the use of novel oral immunomodulatory drugs (IMiDs; lenalidomide and thalidomide) among beneficiaries with myeloma, who can receive either orally administered or parenteral (bortezomib-based) therapy. Methods Using SEER-Medicare data, we identified Part D beneficiaries diagnosed with myeloma in 2007 to 2011...
