New non-sputum biomarker tests for active tuberculosis (TB) diagnostics are of highest priority for global TB control. We performed in-depth proteomic analysis using the 4000-plex SOMAscan assay on 1470 serum samples from seven TB-endemic countries. All samples were from patients with symptoms and signs suggestive of active pulmonary TB that were systematically confirmed or ruled-out for TB by culture and clinical follow-up. HIV-coinfection was present in 34%and 22% were sputum smear-negative. Serum protein biomarkers were identified by stability selection using L1-regularized logistic regression and by Kolmogorov-Smirnov (KS) statistics...

A series of Er(3+)/Tm(3+) co-doped fluoride (ZBLAN) glasses and fibers was prepared and their fluorescence spectra was measured under excitation at 793 nm and 980 nm. Correlation between the self-absorption effect of rare-earth ions and the shift of the emission peak was investigated. With the increasing length of fiber, the emission peaks red-shift when self-absorption occurs at the upper level of emission transition or blue-shift when that occurs at the lower level. As a result of the strong self-absorption effect, Er(3+)/Tm(3+) co-doped fibers mainly yield 1390-1470, 1850-1980, and 2625-2750 nm emissions when excited at 793 nm, and 1480-1580, 1800-1980, and 2625-2750 nm emissions when excited at 980 nm...

Psychotropic substances (PSs) are known to affect air and waters, while scarce attention has been paid to their occurrence in settled dusts although they can reach important concentrations there; moreover, no procedures have been developed for this specific purpose. In this study, a list of PSs (i.e., nicotine, cotinine, caffeine, cocaine, cannabinol, Δ(9)-tetrahydrocannabinol, cannabidiol, amphetamine, heroin, and methadone) were characterized in dusts from Rome and Fiumicino international airport, Italy, and from Ouargla city, Algeria...

BACKGROUND: Daily oral tenofovir-based pre-exposure prophylaxis (PrEP) is high efficacious for HIV prevention among women with high adherence. However, the effect of abnormal vaginal microbiota on PrEP efficacy is of concern. We investigated whether bacterial vaginosis modified the efficacy of oral PrEP. METHODS: We used prospectively collected data from women in the Partners PrEP Study, a placebo-controlled trial of daily oral PrEP (either tenofovir monotherapy or a combination of tenofovir and emtricitabine) in HIV serodiscordant couples aged 18 years or older in Kenya and Uganda that showed high efficacy in women...

A basket-integrated optical device is developed to consistently treat tubular tissue by centering an optical diffuser in the lumen. Four nitinol arms in conjunction with the optical diffusing applicator are deployed to induce homogeneous circumferential light emission and concentric photothermal coagulation on tracheal tissue. 1470-nm laser light is employed for the tissue testing at various irradiation conditions and evaluated in terms of thermal gradient and temperature evolution. Preliminary experiments on liver tissue demonstrate the concentric development of the radial thermal coagulation in the tissue (eccentric ratio = ~5...

The influence of infrared laser pulses on intracellular Ca(2+) signaling was investigated in neural cell lines with fluorescent live cell imaging. The probe Fluo-4 was used to measure Ca(2+) in HT22 mouse hippocampal neurons and non-electrically excitable U87 human glioblastoma cells exposed to 50-500 ms infrared pulses at 1470 nm. Fluorescence recordings of Fluo-4 demonstrated that infrared stimulation induced an instantaneous intracellular Ca(2+) transient with similar dose-response characteristics in hippocampal neurons and glioblastoma cells (half-maximal effective energy density EC50 of around 58 J...

Methane emissions from oil and gas facilities can exhibit operation-dependent temporal variability; however, this variability has yet to be fully characterized. A field campaign was conducted in June 2014 in the Eagle Ford basin, Texas, to examine spatiotemporal variability of methane emissions using four methods. Clusters of methane-emitting sources were estimated from 14 aerial surveys of two ("East" or "West") 35 × 35 km grids, two aircraft-based mass balance methods measured emissions repeatedly at five gathering facilities and three flares, and emitting equipment source-types were identified via helicopter-based infrared camera at 13 production and gathering facilities...

BACKGROUND: Varices and venous insufficiency are common and serious health problems in the general population which affect quality of life. Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux, and the endovenous laser ablation (EVLA) method has been widely accepted all over the world. In this method, ablation is provided by a laser fiber inserted into the lumen of the vein. Initially, the fibers were 810 nm, but today the fibers are usually 940, 980, or 1470 nm...

A robust plasmonic semiconductor-based Mach-Zehnder interferometer (MZI), which consists of a semiconductor layer with a microslit flanked by two identical microgrooves, is proposed and investigated for the terahertz sensing. The microgrooves reflect the surface plasmon polariton waves toward the microslit, where they interfere with the transmitted terahertz wave. The interference pattern is determined by the permittivities of the sensing material and semiconductor (i.e., temperature dependent), making the structure useful for the refractive index (RI) and temperature detection...

We demonstrate a functional rotating electrothermal technique for rapidly concentrating and sorting a large number of particles on a microchip by the combination of particle dielectrophoresis (DEP) and inward rotating electrothermal (RET) flows. Different kinds of particles can be attracted (positive DEP) to or repelled (negative DEP) from electrode edges, and then the n-DEP responsive particles are further concentrated in the heated region by RET flows. The RET flows arise from the spatial inhomogeneous electric properties of fluid caused by direct infrared laser (1470 nm) heating of solution in a rotating electric field...

Microcystins (MCs) are a family of cyanotoxins and pose detrimental effects on human, animal, and ecological health. Conventional water treatment processes have limited success in removing MCs without producing harmful byproducts. Therefore, there is an urgent need for cost-effective and environmentally-friendly methods for treating MCs. The objective of this study was to develop sustainable and non-chemical-based methods for controlling MCs, such as using cold plasma and ultra violet (UV) light with titanium dioxide (TiO₂) coating, which can be applied for diverse scale and settings...

Endovenous laser ablation is an effective and minimally invasive alternative to surgical removal of incompetent veins. However, many controversies concerning optimal laser parameters usage in this procedure still remain. The purpose of this experimental study was to assess the adequate parameters required for vein wall destruction and to evaluate the role of fiber pullback velocity on vessel wall degradation. Varicose vein segments were treated with 1470-nm diode laser 3 to 9.5 W in power. The fiber moved through the vein at a velocity of 0...
