Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA

In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification difficult due to genotypic similarity. Even so, the most likely mother could be identified unambiguously among offspring in most of the clutches studied. Two non-parental females displayed maternal behavior which would have misled managers in assigning maternity based on behavior alone. This set of variable loci demonstrates the utility of parentage testing in captive propagation programs

Fourier Magnetic Imaging with Nanoscale Resolution and Compressed Sensing Speed-up using Electronic Spins in Diamond

Optically-detected magnetic resonance using Nitrogen Vacancy (NV) color centres in diamond is a leading modality for nanoscale magnetic field imaging, as it provides single electron spin sensitivity, three-dimensional resolution better than 1 nm, and applicability to a wide range of physical and biological samples under ambient conditions. To date, however, NV-diamond magnetic imaging has been performed using real space techniques, which are either limited by optical diffraction to 250 nm resolution or require slow, point-by-point scanning for nanoscale resolution, e.g., using an atomic force microscope, magnetic tip, or super-resolution optical imaging. Here we introduce an alternative technique of Fourier magnetic imaging using NV-diamond. In analogy with conventional magnetic resonance imaging (MRI), we employ pulsed magnetic field gradients to phase-encode spatial information on NV electronic spins in wavenumber or k-space followed by a fast Fourier transform to yield real-space images with nanoscale resolution, wide field-of-view (FOV), and compressed sensing speed-up.Comment: 31 pages, 10 figure

A Policy-Ready Public Health Guidebook of Strategies and Indicators to Promote Financial Well-Being and Address Financial Strain in Response to COVID-19

Introduction The COVID-19 pandemic has adversely affected the financial well-being of populations globally, escalating concerns about links with health care and overall well-being. Governments and organizations need to act quickly to protect population health relative to exacerbated financial strain. However, limited practice and policy-relevant resources are available to guide action, particularly from a public health perspective, that is, targeting equity, social determinants of health, and health-in-all policies. Our study aimed to create a public health guidebook of strategies and indicators for multisectoral action on financial well-being and financial strain by decision makers in high-income contexts. Methods We used a multimethod approach to create the guidebook. We conducted a targeted review of existing theoretical and conceptual work on financial well-being and strain. By using rapid review methodology informed by principles of realist review, we collected data from academic and practice-based sources evaluating financial well-being or financial strain initiatives. We performed a critical review of these sources. We engaged our research–practice team and government and nongovernment partners and participants in Canada and Australia for guidance to strengthen the tool for policy and practice. Results The guidebook presents 62 targets, 140 evidence-informed strategies, and a sample of process and outcome indicators. Conclusion The guidebook supports action on the root causes of poor financial well-being and financial strain. It addresses a gap in the academic literature around relevant public health strategies to promote financial well-being and reduce financial strain. Community organizations, nonprofit organizations, and governments in highincome countries can use the guidebook to direct initiative design, implementation, and assessmen

The Generation of Successive Unmarked Mutations and Chromosomal Insertion of Heterologous Genes in Actinobacillus pleuropneumoniae Using Natural Transformation

We have developed a simple method of generating scarless, unmarked mutations in Actinobacillus pleuropneumoniae by exploiting the ability of this bacterium to undergo natural transformation, and with no need to introduce plasmids encoding recombinases or resolvases. This method involves two successive rounds of natural transformation using linear DNA: the first introduces a cassette carrying cat (which allows selection by chloramphenicol) and sacB (which allows counter-selection using sucrose) flanked by sequences to either side of the target gene; the second transformation utilises the flanking sequences ligated directly to each other in order to remove the cat-sacB cassette. In order to ensure efficient uptake of the target DNA during transformation, A. pleuropneumoniae uptake sequences are added into the constructs used in both rounds of transformation. This method can be used to generate multiple successive deletions and can also be used to introduce targeted point mutations or insertions of heterologous genes into the A. pleuropneumoniae chromosome for development of live attenuated vaccine strains. So far, we have applied this method to highly transformable isolates of serovars 8 (MIDG2331), which is the most prevalent in the UK, and 15 (HS143). By screening clinical isolates of other serovars, it should be possible to identify other amenable strains

Reviewing, indicating, and counting books for modern research evaluation systems

In this chapter, we focus on the specialists who have helped to improve the conditions for book assessments in research evaluation exercises, with empirically based data and insights supporting their greater integration. Our review highlights the research carried out by four types of expert communities, referred to as the monitors, the subject classifiers, the indexers and the indicator constructionists. Many challenges lie ahead for scholars affiliated with these communities, particularly the latter three. By acknowledging their unique, yet interrelated roles, we show where the greatest potential is for both quantitative and qualitative indicator advancements in book-inclusive evaluation systems.Comment: Forthcoming in Glanzel, W., Moed, H.F., Schmoch U., Thelwall, M.

Computed tomography as an adjunct to ultrasound in the diagnosis of acute acalculous cholecystitis

The sonographic and computed tomographic (CT) findings were reviewed in 17 patients with acute acalculous cholecystitis (AAC) over a 6-year period from 1984 to 1989. Of the six patients in whom both ultrasound and CT were performed, CT revealed marked gallbladder (GB) wall abnormalities, including perforation, and pericholecystic fluid collections in five patients not demonstrated by sonography. Of the total group, five patients had GB wall thicknesses of ≤ 3 mm (normal) at pathologic examination, which demonstrated a spectrum of disease ranging from acute hemorrhagic/necrotizing, to gangrenous acalculous cholecystitis with perforation. Sonography was falsely negative or significantly underestimated the severity of AAC in seven of the 13 patients examined by sonography. CT because of its superior ability to assess pericholecystic inflammation may provide additional diagnostic information even after a thorough sonographic study in cases of AAC.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/48138/1/261_2005_Article_BF01887331.pd

Embodying prison pain: women’s experiences of self-injury in prison and the emotions of punishment

This paper explores the meanings and motivations of self-injury practices as disclosed in interviews with a small group of female former prisoners in England. In considering their testimonies through a feminist perspective, I seek to illuminate aspects of their experiences of imprisonment that go beyond the ‘pains of imprisonment’ literature. Specifically, I examine their accounts of self-injury with a focus on the embodied aspects of their experiences. In so doing, I highlight the materiality of the emotional harms of their prison experiences. I suggest that the pains of imprisonment are still very much inscribed on and expressed through the prisoner’s body. This paper advances a more theoretically situated, interdisciplinary critique of punishment drawn from medical-sociological, phenomenological and feminist scholarship
