Association of Perceived Stress and Discrimination on Medication Adherence among Diverse Patients with Uncontrolled Hypertension.

Background: Uncontrolled hypertension is a significant risk factor for cardiovascular morbidity and mortality. In the United States, many patients remain uncontrolled, in part, due to poor medication adherence. Efforts to improve hypertension control include not only attending to medical management of the disease but also the social determinants of health, which impact medication adherence, and ultimately blood pressure control.

Discrimination and Latino Health: A Systematic Review of Risk and Resilience.

Introduction: As anti-immigrant hostility toward Latino populations grows, more fervent attention is needed to consider strength-based approaches to attenuate the effects of perceived discrimination. This systematic review synthesizes the evidence about the effects of racial/ethnic discrimination on mental, physical, and health behaviors of Latinos and examines the coping mechanisms and cultural factors that attenuate the negative association between discrimination and health among adult Latinos living in the United States.

Method: The search criteria included articles that (a) examined ethnic/racial discrimination in relationship to a health outcome, (b) had study samples composed of least 25% Latino adults, and (c) were written in English.

Raman evidence for pressure-induced formation of diamondene.

Despite the advanced stage of diamond thin-film technology, with applications ranging from superconductivity to biosensing, the realization of a stable and atomically thick two-dimensional diamond material, named here as diamondene, is still forthcoming. Adding to the outstanding properties of its bulk and thin-film counterparts, diamondene is predicted to be a ferromagnetic semiconductor with spin polarized bands. Here, we provide spectroscopic evidence for the formation of diamondene by performing Raman spectroscopy of double-layer graphene under high pressure.

Inflammatory and hyperalgesic effects of oxidized multi-walled carbon nanotubes in rats.

We evaluated local inflammatory activity of oxidized multiwalled carbon nanotubes in rat experimental models of acute inflammation (paw edema and hyperalgesia) by analyzing their toxicity in non-mesoendothelial tissues. Subcutaneous injection of the nanotubes induced paw edema, that was maximal in the first 2 h after administration at 0.1 mg/kg (43.

Structural and proactive safety aspects of oxidation debris from multiwalled carbon nanotubes.

The removal of oxidation debris from the oxidized carbon nanotube surface with a NaOH treatment is a key step for an effective functionalization and quality improvement of the carbon nanotube samples. In this work, we show via infrared spectroscopy and ultrahigh resolution and accuracy mass spectrometry that oxidation debris obtained from HNO(3)-treated multiwalled carbon nanotubes is a complex mixture of highly condensed aromatic oxygenated carbonaceous fragments. We have also evaluated their cytotoxicity by using BALB/c 3T3 mouse fibroblasts and HaCaT human keratinocytes as models.
