The multiresistant Staphylococcus capitis clone NRCS-A is a major pathogen in neonates worldwide. We show that NRCS-A grows as mauve colonies with a cream-color halo after a 5-day incubation on MRSA Brilliance 2 agar (Oxoid®). This innovative protocol will ease the screening of clinical and environmental niches of this clone.

Theists often receive the benefit of being stereotyped as trustworthy and moral, whereas atheists are viewed as untrustworthy and immoral. The extreme divergence between the stereotypes of theists and atheists suggests that mental images of the two groups may also diverge. We investigated whether people have biased mental images of theists and atheists. The results suggest that mental images of theists are associated with more positive attributes than images of atheists (Study 1), and these mental images influence who is believed to behave morally and immorally (Study 2)...

The lungs are one of the most common organs to which cancer metastasizes, but are a location not common for uterine sarcoma. A malignant mixed Müllerian tumor (MMMT) of the uterus is an extremely rare and aggressive sarcoma, characterized by a mixture of epithelial and mesenchymal components. There are few reports regarding the pulmonary metastasis from MMMTs. The present study presents the case of a 58-year-old woman with hemoptysis and post-menopausal vaginal bleeding. The woman was initially diagnosed with invasive aspergillosis based on a chest computed tomography (CT) scan showing multiple pulmonary nodular opacities surrounded by a ground-glass attenuation halo (halo-sign)...

A 38-year-old woman with metastatic breast carcinoma reported seeing "halos and flashes" in her left eye. Funduscopic exam revealed an elevated mass in the choroid of the left globe consistent with metastasis. Subsequent (18)F-FDG PET/CT revealed focal uptake in the nasal aspect of the left choroid of the eye corresponding to the mass seen on the funduscopic exam. Through correlation with the PET/CT, the lesion was retrospectively identified on the MRI. (18)F-FDG PET/CT post-radiotherapy showed complete response and thus supports that this imaging modality can be used for diagnosis and monitoring response...

In this study, an effort was made to identify an efficient phosphate solubilizing bacterial strain from chromium contaminated agricultural soils. Based on the formation of a solubilized halo around the colonies on Pikovskaya's agar amended with chromium (VI), 10 strains were initially screened out. Out of 10, strain CPSB4, which showed significantly high solubilization zone at different chromium concentrations, was selected for further study. The strain CPSB4 showed significant plant growth promotion traits with chromium (VI) stress under in-vitro conditions in broth...

Objectives: To explore whether the increase in the intima-media thickness (IMT) in arteriosclerotic disease correlates with the increase in the IMT in temporal arteries (TAs) and if that could mimic the US GCA halo sign. Methods: Consecutive patients ⩾50 years old with high vascular risk and without signs or symptoms of GCA were included. The carotid US IMT measurements were obtained using a standardized software radiofrequency-tracking technology. Colour Doppler US and grey-scale measurements of the IMT in the branches of both TAs were performed by a second sonographer using a 22 MHz probe...

Porous silicon (pSi) based microarrays are attractive because pSi: (i) can be modified in many ways, (ii) possesses a high surface area, and (iii) exhibits strong photoluminescence (PL). These characteristics make pSi-based microarrays candidates for a host of applications including sensing, optoelectronic devices, and photodetectors. Microarray fabrication requires a high-throughput approach to produce chemically modified, spatially isolated spots on a particular substrate. The most stable platforms are characterized by covalent attachment to the substrate...

Scattering is used to probe matter and its interactions in all areas of physics. In ultracold atomic gases, control over pairwise interactions enables us to investigate scattering in quantum many-body systems. Previous experiments on colliding Bose-Einstein condensates have revealed matter-wave interference, haloes of scattered atoms, four-wave mixing and correlations between counter-propagating pairs. However, a regime with strong stimulation of spontaneous collisions analogous to superradiance has proved elusive...

The amorphization of 18 different drugs on milling with one mole equivalent sodium taurocholate (NaTC) was investigated. In all cases the X-ray powder pattern showed an amorphous halo after milling at room temperature or after cryomilling and 14 of the 18 coamorphous drug-NaTC systems were physically stable for between one to eleven months under ambient storage conditions. In three cases, namely carbamazepine-NaTC, indomethacin-NaTC and mefenamic acid-NaTC, significant dissolution advantages over the crystalline drugs were observed, both for the freshly prepared samples and after storage for seven months...

Pulmonary cryptococcosis is most commonly reported in immunocompromised patients, whereas immunocompetent hosts are rarely affected and may be asymptomatic, resulting in reduced diagnostic performance of computed tomography (CT) imaging. Thus, the aim of the present study was to review the plain and contrast-enhanced chest CT scan findings of primary pulmonary cryptococcosis in immunocompetent patients, with the aim of improving the diagnosis of this type of pulmonary disease. In the present study, a total of 27 immunocompetent patients of clinically confirmed pulmonary cryptococcosis were analyzed retrospectively...
