Plane-wave theory for fluid-embedded isotropic plates is often used in ultrasonic guided-wave applications, and to estimate wall thickness, corrosion, or sound velocities in plates and pipes. In such structures, measured ultrasonic transmission through the solid material is affected by acoustic beam diffraction effects, and the results may deviate from plane-wave descriptions, which are insufficient to describe the complex effects that occur. When exciting a fluid-embedded steel plate with a pulsed ultrasonic beam at normal incidence, resonance frequency downshift, axial sound pressure level (SPL) increase, and beam narrowing have been observed, for measured resonance peaks in the frequency regions of certain leaky Lamb mode branches of the plate...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

BACKGROUND: Extremely preterm infants born at the border of viability (22-24 weeks' gestation) have high rates of death and lasting disability. Ex vivo uterine environment therapy is an experimental neonatal intensive care strategy that provides gas exchange using parallel membranous oxygenators connected to the umbilical vessels, sparing the extremely preterm cardiopulmonary system from ventilation-derived injury. OBJECTIVE: In this study, we aimed to refine our ex vivo uterine environment therapy platform to eliminate fetal infection and inflammation, while simultaneously extending the duration of hemodynamically stable ex vivo uterine environment therapy to 1 week...

The neurovascular coupling response has been defined for the adult brain but in the neonate non-invasive measurement of local cerebral perfusion using NIRS or BOLD fMRI have yielded variable and inconsistent results, including negative responses suggesting decreased perfusion and localised tissue tissue hypoxia. Also, the impact of permissive hypercapnia (Pa CO2  > 50 mmHg) in the management of neonates on cerebrovascular responses to somatosensory input is unknown. Using NIRS to measure changes in cerebral oxy- and deoxy-haemoglobin (ΔoxyHb, ΔdeoxyHb) in 8 anaesthetised newborn lambs, we studied the cerebral haemodynamic functional response to left median nerve stimulation using stimulus trains of 1...

Robot-assisted radical cystectomy (RARC) has been adopted widely in many centres, owed largely to the success of robot-assisted laparoscopic prostatectomy (RALP). It aims to replicate the oncological outcomes of open radical cystectomy (ORC), while providing a shorter recovery period. Despite this, previous RCTs have failed to show a benefit for RARC over ORC. These trials have compared extracorporeal RARC (eRARC) with ORC, which requires a further incision to mobilise the bowel for urinary reconstruction with an open technique...

Fibroblast growth factor 5 (FGF5) regulates hair length in humans and a variety of other animals. To investigate whether FGF5 has similar effects in sheep, we used CRISPR/Cas9 to generate loss-of-function mutations with the FGF5 gene in Chinese Merino sheep. A total of 16 lambs were identified with genetic mutations within the targeting locus: 13 lambs had biallelic modifications and 3 lambs had monoallelic modifications. Characterization of the modifications revealed that 13 were frame shift mutations that led to premature termination; the other 3 were in-frame deletions...

Contagious ecthyma, caused by orf virus (ORFV), is an epitheliotrophic contagious disease with zoonotic implications that mainly affects sheep, goats, wild ruminants, and humans. Recently, a novel ORFV strain, OV/HLJ/04, was successfully isolated from the skin and mucosal lesions of a goat with severe clinical sore mouth symptoms in Heilongjiang province of China. The OV/HLJ/04 isolate was characterized by electron microscopy, serological tests, and experimental reproduction of disease. The purified virions exhibited a typical ovoid shape when observed by electron microscopy...

Upon mechanical pulling at either terminal end, β barrel outer membrane proteins stepwise unfold β strands or β hairpins until entirely extracted from the membrane. This unique unfolding pathway has been described for β barrels comprising 8, 14, or 22 β strands. Here we mechanically unfold the 18-stranded β barrel outer membrane protein LamB from Escherichia coli. We find that its mechanical unfolding pathway is shaped by the stepwise unfolding of β hairpins. However, we also observe that β hairpins can unfold groupwise...

BACKGROUND: There is currently no disease-modifying treatment available to halt or delay the progression of the disease pathology in dementia. An agreed core set of the best-available and most appropriate outcomes for disease modification would facilitate the design of trials and ensure consistency across disease modification trials, as well as making results comparable and meta-analysable in future trials. OBJECTIVES: To agree a set of core outcomes for disease modification trials for mild to moderate dementia with the UK dementia research community and patient and public involvement (PPI)...

In order to gain basic insight into the interaction between ultrasonic guided waves and structural discontinuities with contacting surfaces, the transmission characteristics of Lamb waves at contacting edges of two plates are studied experimentally. The edges of two 2.5-mm thick aluminum alloy plates are mated together to constitute a contacting interface of plates and subjected to different levels of compressive loading. The transmission measurements of the lowest-order symmetric (S0) and antisymmetric (A0) Lamb modes across the contacting interface are performed in a frequency range below the cut-off frequencies of the higher-order modes...

BACKGROUND: Falls are a serious cause of morbidity and cost to individuals and society. Evidence suggests that foot problems and inappropriate footwear may increase the risk of falling. Podiatric interventions could help reduce falls; however, there is limited evidence regarding their clinical effectiveness and cost-effectiveness. OBJECTIVES: To determine the clinical effectiveness and cost-effectiveness of a multifaceted podiatry intervention for preventing falls in community-dwelling older people at risk of falling, relative to usual care...

Leukotoxin producing (lkt+) members of Pasteurellaceae, particularly Mannheimia haemolytica and Bibersteinia trehalosi are important pathogens of pneumonia in bighorn sheep (BHS; Ovis canadensis), causing fatal disease. Predisposing or concurrent infection with Mycoplasma ovipneumoniae enhances the severity of the disease, resulting in increased morbidity and mortality. Several studies have investigated the effectiveness of vaccines against lkt+ members of Pasteurellaceae in preventing fatal pneumonia in BHS...

Hobi-like viruses comprise an unclassified group of bovine pestiviruses related to bovine viral diarrhea virus 1 (BVDV-1) and 2 (BVDV-2). These viruses were originally identified in fetal bovine serum from Brazilian origin and, subsequently, isolated from diseased animals in several countries. Herein we performed an antigenic characterization of eight Brazilian HoBi-like viruses isolated from persistently infected (PI) animals and from gastroenteric disease (2007-2015). Phylogenetic analysis based on the 5' unstranslated region (UTR) clustered these viruses with other HoBi-like viruses from European and Asiatic origin...

Genetic diversity underpins the ability of populations to persist and adapt to environmental changes. Substantial empirical data show that genetic diversity rapidly deteriorates in small and isolated populations due to genetic drift, leading to reduction in adaptive potential and fitness and increase in inbreeding. Assisted gene flow (e.g. via translocations) can reverse these trends, but lack of data on fitness loss and fear of impairing population "uniqueness" often prevents managers from acting. Here, we use population genetic and riverscape genetic analyses and simulations to explore the consequences of extensive habitat loss and fragmentation on population genetic diversity and future population trajectories of an endangered Australian freshwater fish, Macquarie perch Macquaria australasica...

The OK cell line derived from kidney of a female opossum Didelphis virginiana has proven to be a useful model in which to investigate the unique regulation of ion transport and membrane trafficking mechanisms in the proximal tubule (PT). Sequence data and comparison of the transcriptome of this cell line to eutherian mammal PTs would further broaden the utility of this culture model. However, genomic sequence for Didelphis virginiana is not available and although a draft genome sequence for the opossum Monodelphis domestica (sequenced in 2012 by the Broad Institute) exists, transcripts sequenced from both species show significant divergence...

Muscle Ankyrin Repeat Proteins (MARPs) are a family of titin-associated stress response molecules and putative transducers of stretch-induced signalling in skeletal muscle. In cardiac muscle, Cardiac Ankyrin Repeat Protein (CARP) and Diabetes-Related Ankyrin Repeat Protein (DARP) reportedly redistribute from binding sites on titin to the nucleus following prolonged stretch. However, it is unclear whether Ankyrin repeat-domain protein2 (Ankrd2) shows comparable stretch-induced redistribution to the nucleus. We measured in rested human skeletal muscle 1) the absolute amount of MARPs, and 2) the distribution of Ankrd2 and DARP in both single fibers and whole muscle preparations...

In this work, fundamental symmetric Lamb wave S0 mode is characterized in terms of its velocity variation as function of the interfacial conditions between solid bodies in contact. Imperfect contact conditions are numerically and experimentally determined by using ultrasonic Lamb wave propagation parameters. For the study, an experimental system was used, formed by two solid aluminum rods (25.4mm in diameter) axially loading a thin aluminum plate to control contact interfacial stiffness. The axially applied load on the aluminum plate was varied from 0MPa to 10MPa...

This article begins with the history of the rise and fall of the state hospitals and subsequent criminalization of persons with serious mental illness (SMI). Currently, there is a belief among many that incarceration has not been as successful as hoped in reducing crime and drug use, both for those with and those without SMI. Moreover, overcrowding in correctional facilities has become a serious problem necessitating a solution. Consequently, persons with SMI in the criminal justice system are now being released in large numbers to the community and hopefully treated by public sector mental health...
