This article describes the fabrication and characterization of a pH sensor for monitoring the wound status. The pH sensitive layer consists of a graphene oxide (GO) layer obtained by drop-casting 5 μΐ of GO dispersion onto the working electrode of a screen-printed substrate. Sensitivity was 31.8 mV/pH with an accuracy of 0.3 unit of pH. Open-circuit potentiometry was carried out to measure pH in an exudate sample. The GO pH sensor proved to be reliable as the comparison with results obtained from a standard glass electrode pH-meter showed negligible differences (<; 0...

The majority of patients with angina or heart failure have coronary artery disease. Left main bifurcations are particularly susceptible to pathological narrowing. Flow is a major factor of atheroma development, but limitations in imaging technology such as spatio-temporal resolution, signal-to-noise ratio (SNRv), and imaging artefacts prevent in vivo investigations. Computational fluid dynamics (CFD) modelling is a common numerical approach to study flow, but it requires a cautious and rigorous application for meaningful results...

Exclusion is the determination by a latent print examiner that two friction ridge impressions did not originate from the same source. The concept and terminology of exclusion vary among agencies. Much of the literature on latent print examination focuses on individualization, and much less attention has been paid to exclusion. This experimental study assesses the associations between a variety of factors and exclusion determinations. Although erroneous exclusions are more likely to occur on some images and for some examiners, they were widely distributed among images and examiners...

Since the cell-based cDNA microarray (CBCM) technique has been a useful tool for gain-of-function studies, many investigators have used CBCMs to identify interesting genes. However, this method requires better-established conditions to ensure high reverse transfection efficiency without cross-contamination. Therefore, we optimized CBCM techniques through various means. We determined that Lipofectamine 2000 was the most appropriate transfection reagent by evaluating eight commercialized reagents, and we determined that the most effective concentrations for printing solution constituents were 0...

OBJECTIVE: The vision of bioelectronic medicine is to treat disease by modulating the signaling of visceral nerves near various end organs. In small animal models, the nerves of interest can have small diameters and limited surgical access. New high-resolution methods for building nerve interfaces are desirable. In this study, we present a novel nerve interface and demonstrate its use for stimulation and recording in small nerves. APPROACH: We design and fabricate micro-scale electrode-laden nanoclips capable of interfacing with nerves as small as 50 µm in diameter...

In this article, I examine how African American soldiers and veterans experienced and shaped federally sponsored health care during and after World War I. Building on studies of the struggles of Black leaders and health care providers to win professional and public health advancement in the 1920s and 1930s, and of advocates to mobilize for health care rights in the mid-20th century, I focus primarily on the experiences and activism of patients in the interwar years. Private and government correspondence, congressional testimony, and reports from Black newspapers reveal that African American soldiers and veterans communicated directly with policymakers and bureaucrats regarding unequal treatment, assuming roles as "policy actors" who viewed health and medical care as "politics by other means...

OBJECTIVES: To examine the relationships between universal mandatory reporting (UMR), child physical abuse reporting, and the moderating effect of UMR on physical abuse report outcomes by report source. METHODS: We used a national data set of 204 414 children reported for physical abuse in 2013 to compare rates of total and confirmed reports by states or territories with and without UMR. We estimated odds and predicted probabilities of confirming a physical abuse report made by professional versus nonprofessional reporters, accounting for the moderating effect of UMR and individual-level characteristics...

We investigated links between police brutality and poor health outcomes among Blacks and identified five intersecting pathways: (1) fatal injuries that increase population-specific mortality rates; (2) adverse physiological responses that increase morbidity; (3) racist public reactions that cause stress; (4) arrests, incarcerations, and legal, medical, and funeral bills that cause financial strain; and (5) integrated oppressive structures that cause systematic disempowerment. Public health scholars should champion efforts to implement surveillance of police brutality and press funders to support research to understand the experiences of people faced with police brutality...

OBJECTIVES: To highlight contextual factors tied to increased blood lead level (BLL) risk following the lead-in-water contamination in Flint, Michigan. METHODS: Using geocoded BLL data collected in 2013 and 2015 and areal interpolation, we predicted BLLs at every residential parcel in the city. We then spatially joined social and built environmental variables to link the parcels with neighborhood-level factors that may influence BLLs. RESULTS: When we compared levels before and during the water crisis, we saw the highest estimates of predicted BLLs during the water crisis and the greatest changes in BLLs in neighborhoods with the longest water residence time in pipes (μ = 2...
