Ustekinumab (Stelara(®)) has been recently approved in the EU and the USA as intravenous induction and subcutaneous maintenance therapy for adult patients with moderately to severely active Crohn's disease who have failed or were intolerant to treatment with immunomodulators, corticosteroids or at least one tumour necrosis factor (TNF) antagonist. Ustekinumab, a monoclonal antibody to the shared p40 subunit of the proinflammatory interleukin (IL)-12 and IL-23 cytokines, has a unique mechanism of action distinct from that of TNF antagonists...

The low frequency Raman scattering from gold nanoparticle bimodal assemblies with controlled size distributions has been studied. Special care has been paid to determining the size dependence of the Raman intensity corresponding to the quadrupolar Lamb mode. Existing models based on a microscopic description of the scattering mechanism in small particles (bond polarizability, dipole induced dipole models) predict, for any Raman-active Lamb modes, an inelastic intensity scaling as the volume of the nanoparticle...

Myogenic factor 5 (MYF5) plays an important role in regulating skeletal muscle, but to date there have been no reports on whether the gene is variable and whether this variation is associated with meat yield in sheep. In this study, four variants (A to D) of ovine MYF5 containing two Single Nucleotide Polymorphisms (SNPs) and one basepair (bp) insertion/deletion were detected by Polymerase Chain Reaction - Single Stranded Conformational Polymorphism (PCR-SSCP) analysis. Breed differences in variant frequencies were observed...

The coherent interaction between quantum emitters and photonic modes in cavities underlies many of the current strategies aiming at generating and controlling photonic quantum states. A plasmonic nanocavity provides a powerful solution for reducing the effective mode volumes down to nanometre scale, but spatial control at the atomic scale of the coupling with a single molecular emitter is challenging. Here we demonstrate sub-nanometre spatial control over the coherent coupling between a single molecule and a plasmonic nanocavity in close proximity by monitoring the evolution of Fano lineshapes and photonic Lamb shifts in tunnelling electron-induced luminescence spectra...

We hypothesised that probiotic feeding would alter the fatty acid (FA) profile of sheep's milk. Sixteen lactating ewes, kept under the same feeding and management practices, were randomly allocated to receive either a control diet or the same diet supplemented with a commercial multi-strain bacterial probiotic. Milk fat FA contents were monitored fortnightly for eight consecutive weeks from 14 d after lambing. Probiotic supplementation increased the contents of butyric and caproic acids in milk fat and had no negative effects on other relevant FA from the human's health point of view (i...

On 25th May 2016, the U.S. EPA released reference doses (RfDs) for Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA) of 20ng/kg/day, which were much more conservative than previous values. These RfDs rely on the choices of animal point of departure (PoD) and the toxicokinetics (TK) model. At this stage, considering that the human evidence is not strong enough for RfD determination, using animal data may be appropriate but with more uncertainties. In this article, the uncertainties concerning RfDs from the choices of PoD and TK models are addressed...

Times for the progressive breakdown of 95 lamb carcases were recorded to determine the impact of carcase weight and GR tissue depth on the time and therefore cost to produce value added retail cuts. Further analysis also assessed the potential to use these carcase traits as predictors of fabrication times. Regression modeling demonstrated there was a limited ability to predict the difference in time to fabricate mid value-added (R(2)=0.18) and extreme value-added (R(2)=0.12) cuts compared to traditional cuts, suggesting that other factors need to be considered...

A nonlinear Lamb-wave-based method for fatigue crack detection in steel plates with and without carbon fibre reinforcement polymer (CFRP) reinforcement is presented in this study. Both numerical simulation and experimental evaluation were performed for Lamb wave propagation and its interaction with a fatigue crack on these two steel plate types. With the generation of the second harmonic, the damage-induced wave nonlinearities were identified by surface-bonded piezoelectric sensors. Numerical simulation revealed that the damage-induced wave component at the second harmonic was slightly affected by the existence of CFRP laminate, although the total wave energy was decreased because of wave leakage into the CFRP laminate...

As an important commercial trait for sheep, curly fleece has a great economic impact on production costs and efficiency in sheep industry. To identify genes that are important for curly fleece formation in mammals, a suppression subtractive hybridization analysis was performed on the shoulder skin tissues exposed to two different growth stages of Chinese Tan sheep with different phenotypes (curly fleece and noncurling fleece). BLAST analysis identified 67 differentially expressed genes, of which 31 were expressed lower and 36 were expressed higher in lambs than in adult sheep...

BACKGROUND: Although the patient perspective is implicit in the practice of medicine, research evaluating this remains scarce. In a climate where clinicians and policy-makers constantly strive to achieve more patient-centred models of care, this omission warrants attention. AIM: To assess health-related quality of life (HrQoL) in women under 25 years of age with cervical intra-epithelial neoplasia grade 2 (CIN2) receiving conservative management (colposcopy follow-up, with treatment if necessary) compared with those receiving immediate excisional treatment with large loop excision of the transformation zone (LLETZ)...

BACKGROUND: Naturally occurring mutations in growth and differentiation factor 9 (GDF9) or bone morphogenetic protein 15 (BMP15) genes are associated with increased ovulation rate (OR) and litter size (LS) but also sterility. Observing the Tunisian Barbarine ewes of the "W" flock selected for improved prolificacy, we found prolific and infertile ewes with streaky ovaries. Blood genomic DNA was extracted from a subset of low-ovulating, prolific and infertile ewes of the "W" flock, and the entire coding sequences of GDF9 and BMP15 were sequenced...

Aflatoxins are among the most powerful carcinogens in nature. The major aflatoxin-producing fungi are Aspergillus flavus and A. parasiticus. Numerous crops, including peanut, are susceptible to aflatoxin contamination by these fungi. There has been an increased use of RNA interference (RNAi) technology to control phytopathogenic fungi in recent years. In order to develop molecular tools targeting specific genes of these fungi for the control of aflatoxins, it is necessary to obtain their genome sequences. Although high-throughput sequencing is readily available, it is still impractical to sequence the genome of every isolate...

BACKGROUND: The economic recession produced a rapid rise of unemployment rates that was more visible in Southern European countries. There is evidence that unemployment correlates highly with individuals' poor life satisfaction. OBJECTIVE: To analyse the relationship between life satisfaction, household composition and socioeconomic deprivation in people facing unemployment during the economic recession. METHODS: A sample of 748 unemployed people from Lisbon (Portugal) completed a socio-demographic questionnaire, the Cantril's ladder of life scale, and the latent and manifest benefits of work scale (LAMB)...

Sheep are one of the most frequently used large animal models in stem cell research. However, minimal invasive or noninvasive sources of mesenchymal stem cells (MSCs) in sheep are scarce. In the light of the principles of the 3Rs (reduce, refine, replace), it would therefore be desirable to identify a minimally invasive or noninvasive ovine MSC source. In humans, the chorionic villi of the placenta, which can be noninvasively harvested as part of the afterbirth, have been identified as a rich source of MSCs...

In the hot semi-arid tropical region, extreme summer is a major constraint in sheep production. The growth performance of growing lambs is impaired during the summer. Therefore, the present study was conducted to assess the effect of protection against hot climate on growth performance, physiological response, and endocrine profile of growing lambs under semi-arid tropical environment. All the data in the experiment were presented as mean ± SE. Thirty Malpura lambs with the age of 122.7 ± 6.05 days and body weight of 19...

The rapid discharge of gas and rock fragments during volcanic eruptions generates acoustic infrasound. Here we present results from the inversion of infrasound signals associated with small and moderate gas-and-ash explosions at Santiaguito volcano, Guatemala, to retrieve the time history of mass eruption rate at the vent. Acoustic waveform inversion is complemented by analyses of thermal infrared imagery to constrain the volume and rise dynamics of the eruption plume. Finally, we combine results from the two methods in order to assess the bulk density of the erupted mixture, constrain the timing of the transition from a momentum-driven jet to a buoyant plume, and to evaluate the relative volume fractions of ash and gas during the initial thrust phase...
