Peppermint Oil: Evaluating Efficacy on Nausea in Patients Receiving Chemotherapy in the Ambulatory Setting.

Background: Nausea is one of the most commonly reported side effects in patients receiving chemotherapy. Patients who experience nausea during chemotherapy may also experience depression, metabolic imbalances, dehydration, decreased ability to function, and treatment delays, which can ultimately affect outcomes.

Objectives: This study aimed to determine the efficacy of a cool damp washcloth with peppermint essential oil versus a cool damp washcloth alone on the self-reported intensity of nausea in patients receiving chemotherapy in the outpatient ambulatory setting.

A longitudinal study of the durability of long-lasting insecticidal nets in Zambia.

Background: A key goal of malaria control is to achieve universal access to, and use of, long-lasting insecticidal nets (LLINs) among people at risk for malaria. Quantifying the number of LLINs needed to achieve and maintain universal coverage requires knowing when nets need replacement. Longitudinal studies have observed physical deterioration in LLINs well before the assumed net lifespan of 3 years.

Oxidative cleavage of DNA by pentamethine carbocyanine dyes irradiated with long-wavelength visible light.

Here we report the synthesis of seven symmetrical carbocyanine dyes in which two nitrogen-substituted benz[e]indolium rings are joined by a pentamethine bridge that is meso-substituted with chlorine or bromine versus hydrogen. The heteroatom of benz[e]indolium is modified with a phenylpropyl, methyl, or cationic quaternary ammonium group. In reactions containing micro molar concentrations of halogenated dye, irradiation at 575, 588, 623, or 700nm produces good photocleavage of plasmid DNA.

CD8+ T cells expressing IL-10 are associated with a favourable prognosis in lung cancer.

The dual role of tumour-infiltrating macrophages and lymphocytes on nonsmall cell lung cancer (NSCLC) progression and prognosis may be due to the differential activity of their phenotypes. To investigate the impact of inflammatory cells on NSCLC, we first quantified the number of macrophages (CD68+) and lymphocytes (CD8+ and CD4+) and the percentage of CD8+ cells expressing IL-10 (CD8+/IL-10+) in tumour stroma and epithelium. Then, we evaluated the possible relationships between the numbers of these cells and the clinicopathological features and the overall survival of patients.
