Gastrointestinal endoscopy is an important tool for the indentification and treatment of disorders of the gastrointestinal tract. However, nosocomial infections of Helicobacter pylori have been linked to the use of contaminated endoscopes. Disinfectants such as glutaraldehyde, ortho-phthalaldehyde and peracetic acid are generally used in the reprocesssing of endoscopes, but these chemicals are hazardous to human health. Thus, safer reprocessing and disinfecion methods are needed. In this study, we applied a dielectric barrier discharge (DBD) plasma torch for inactivation of H...

Clinical trials of pharmacotherapy in chronic obstructive pulmonary disease (COPD) often include older persons with moderate-to-severe airflow-obstruction, as defined by the Global Initiative for chronic Obstructive Lung Disease (GOLD). In this context, spirometric airflow-obstruction establishes COPD. Because GOLD misidentifies COPD and its severity in older persons, we set out to apply more age-appropriate spirometric criteria from the Global Lung function Initiative (GLI) in a prior clinical trial of COPD pharmacotherapy, specifically the Towards a Revolution in COPD Health (TORCH) trial - N = 6,112, mean age 65 years...

African Americans are disproportionately affected by diabetes and colorectal cancer. Although studies have shown the effectiveness of spiritually based health interventions delivered by community health workers to African Americans, few have described the development of the capacity-building component. This article describes this process. The development of the Healthy Congregations Healthy Communities Program (HCHC) was guided through a community-based participatory research lens and included: 1) establishment of a community coalition; 2) identification by coalition members of churches as the best venues for health promotion strategies among African Americans; 3) recruitment of churches; 4) development of a training manual; 5) recruitment and training of congregational health leaders (CHLs); and 6) "Passing of the torch" from the coalition to the CHLs who implemented the intervention in their congregations...

Many current flame retardant technologies for polymeric materials contain environmentally harmful compounds, negatively impact processing and mechanical properties. In an effort to tackle these issues, graphene oxide (GO) nanocoating was deposited on the surface of polyurethane sponge (PUS) to reduce its flammability via layer-by-layer (LbL) assembly method. The results indicated that GO was evenly distributed on the surface of PUS to form GO coating PUS (PUS@GO) composites. This coating system completely eliminated melt dripping of sponge upon exposure to the direct flame from a butane torch...

Characteristics of a diffusion-bonded sapphire cell for optical experiments with hot metal vapors were investigated. The sapphire cell consisted of sapphire-crystal plates and a borosilicate-glass tube, which were bonded to each other by diffusion bonding without any binders or glues. The glass tube was attached to a vacuum manifold using the standard method applied in glass processing, filled with a small amount of Rb metal by chasing with a torch, and then sealed. The cell was baked at high temperatures, and optical experiments were then performed using rubidium atoms at room temperature...

The health and well-being of cattle is a significant concern for global agricultural output. In dairy production within low and middle income countries (LMICs), there is a significant biosensing challenge in detecting sexually transmitted infection (STI) pathogens during animal husbandry, due in part to difficulties associated with the limited infrastructure for veterinary medicine. Here we demonstrate low-cost, multiplexed and sample-to-answer paper-origami tests for the detection of three bovine infectious reproductive diseases in semen samples, collected at a test site in rural India...

Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to distill the mercury and isolate the gold. Mercury emissions from tailings and vaporised mercury exceed 1000 tonnes each year from ASGM. The health effects on the miners are dire, with inhaled mercury leading to neurological damage and other health issues...

Laser Ablation - Inductively Coupled Plasma - Mass Spectrometry (LA-ICP-MS) is a powerful method to determine the elemental composition of solid-state samples as it combines the high sensitivity and isotope selectivity of ICP-MS detection and the simplicity of laser ablation sampling. This technique enables rapid multiple sampling of the analysed material, such as needed for mapping or in-depth profiling applications. However, the duration of these measurements is practically restricted by the time taken for the particle to be transported from the sampling point to the ICP torch...

Multi-layer/multi-pass welding (MLMPW) technology is widely used in the energy industry to join thick components. During automatic welding using robots or other actuators, it is very important to recognize the actual weld pass position using visual methods, which can then be used not only to perform reasonable path planning for actuators, but also to correct any deviations between the welding torch and the weld pass position in real time. However, due to the small geometrical differences between adjacent weld passes, existing weld position recognition technologies such as structured light methods are not suitable for weld position detection in MLMPW...

Zika virus (ZIKV) is an emerging healthcare threat. The presence of the mosquito Aedes species across South and Central America in combination with complementary climates have incited an epidemic of locally transmitted cases of ZIKV infection in Brazil. As one of the most significant current public health concerns in the Americas, ZIKV epidemic has been a cause of alarm due to its known and unknown complications. At this point, there has been a clear association between ZIKV infection and severe clinical manifestations in both adults and neonates, including but not limited to neurological deficits such as Guillain-Barré syndrome (GBS) and microcephaly, respectively...

BACKGROUND: Fetal anemia is often assumed to be due to red cell alloimmunization and Parvovirus infection, and can lead to hydrops fetalis and death in utero. Other causes, such as mutations of hemoglobin alpha, are less commonly considered. METHODS: We report 7 cases with fetal anemia causing hydrops fetalis. Serial Doppler ultrasound for measurement peak systolic velocity (PSV) of middle cerebral artery (MCA) was used for evaluation of fetal anemia. Fetal anemia is suggested if the MCA/PSV ratio is >1...
