Interactions between pork consumption, CagA status and IL-1B-31 genotypes in gastric cancer.

Aim: To explore potential interactions among Helicobacter pylori (H. pylori), CagA status, interleukin (IL)-1B-31 genotypes, and non-cardiac gastric cancer (GC) risk.

Methods: A case-control study of non-cardia GC was performed at 3 hospitals located in Xi'an, China, between September 2008 and July 2010.

TBNA with and without EBUS: a comparative efficacy study for the diagnosis and staging of lung cancer.

Introduction: Conventional transbronchial needle aspiration (TBNA) has been around for over 30 years with sensitivities approaching 70-90%. Recent development of endobronchial ultrasound (EBUS) TBNA demonstrated even higher sensitivities among experts. However EBUS-TBNA is more costly and less available worldwide than conventional TBNA.

Hydraulic fracturing: paving the way for a sustainable future?

With the introduction of hydraulic fracturing technology, the United States has become the largest natural gas producer in the world with a substantial portion of the production coming from shale plays. In this review, we examined current hydraulic fracturing literature including associated wastewater management on quantity and quality of groundwater. We conclude that proper documentation/reporting systems for wastewater discharge and spills need to be enforced at the federal, state, and industrial level.

The community speaks: understanding ethical values in allocation of scarce lifesaving resources during disasters.

Introduction: Pandemic influenza or other crises causing mass respiratory failure could easily overwhelm current North American critical care capacity. This threat has generated large-scale federal, state, and local efforts to prepare for a public health disaster. Few, however, have systematically engaged the public regarding which values are most important in guiding decisions about how to allocate scarce healthcare resources during such crises.

Subdominant modes in zonal-flow-regulated turbulence.

From numerical solutions of a gyrokinetic model for ion temperature gradient turbulence it is shown that nonlinear coupling is dominated by three-wave interactions that include spectral components of the zonal flow and damped subdominant modes. Zonal flows dissipate very little energy injected by the instability, but facilitate its transfer from the unstable mode to dissipative subdominant modes, in part due to the small frequency sum of such triplets. Although energy is transferred to higher wave numbers, consistent with shearing, a large fraction is transferred to damped subdominant modes within the instability range.

Recent evidence regarding triclosan and cancer risk.

Triclosan is a broad-spectrum antibacterial commonly used in cosmetics, dentifrices, and other consumer products. The compound's widespread use in consumer products and its detection in breast milk, urine, and serum have raised concerns regarding its potential association with various human health outcomes. Recent evidence suggests that triclosan may play a role in cancer development, perhaps through its estrogenicity or ability to inhibit fatty acid synthesis.

Melatonin supplementation to treat the metabolic syndrome: a randomized controlled trial.

Background: Supplemental melatonin may ameliorate metabolic syndrome (MetS) components, but data from placebo-controlled trials are lacking.

Methods: We conducted a double-blind, placebo-controlled, crossover, Phase II randomized pilot clinical trial to estimate the effects of melatonin supplementation on MetS components and the overall prevalence of MetS. We randomized 39 subjects with MetS to receive 8.
