Reinvestigation of essential oil constituents of Blumea malcolmii Hook. f. (Asteraceae) was carried out after 100years using gas chromatography equipped with flame ionisation detector (GC-fID) and gas chromatography coupled with mass spectrometry (GC/MS). Eighteen constituents, representing 99.2% of the total oil, were identified. The major compound was identified by GC/MS and NMR (H-1 and C-13) as carvotanacetone (92.1%). The minor compounds of essential oil have also been identified for the first time in B. malcolmii. The oil was found to be rich in oxygenated monoterpene-type constituents (95.0%). [GRAPHICS]

frederick William faber (1814-1863) became a Roman Catholic priest in 1847. He founded the London Oratory and was its Provost between its foundation in April 1849 and his death. This article explores faber's public role as spiritual director to his congregation, through an examination of his sermons concerned specifically with private spirituality and which mention spirituality within the context of a broader sermon. faber's major preoccupations within these sermons will be explored, and the devotions which he encouraged his parishioners to practice, both in private and in public will be highlighted.

Purpose: To describe the clinical features in a series of 8 patients with cytologically proven granulomatous vitritis in the context of systemic malignancy. Design: Retrospective case review series from 2004 through 2018 to identify all cases of cytologically proven granulomatous vitritis and to analyze its disease associations and causes. Participants: Twenty-three patients with a cytologic diagnosis of granulomatous vitritis were identified, 8 of whom demonstrated systemic malignancy. Main outcome measures: To identify a clinical profile of the 8 cases of granulomatous vitritis occurring in the setting of systemic malignancy, focusing on the timing of the eye presentation compared with the timing of the systemic malignancy. Methods: Patients with a cytologic diagnosis of granulomatous vitritis seeking treatment from 2004 through 2018 were included in this retrospective case series. Case notes were recalled and reviewed for demographic features, medical history, presenting symptoms, investigations, surgical procedures, and follow-up. Results: Twenty-three patients were diagnosed cytologically with granulomatous vitritis. Ten of 23 patients (43%) showed autoimmune and infectious causes, 5 of 23 patients (22%) showed were idiopathic causes, and 8 of 23 patients' (35%) disease was associated with systemic malignancy. In the latter group, the median age at presentation was 70 years (range, 55-89 years). Six patients showed bilateral disease, and the remaining 3 showed unilateral disease. Three of 8 patients showed primary systemic malignancy diagnosed after eye symptoms and 5 of 8 showed malignancy before the eye symptoms. These latter 5 patients all demonstrated a major relapse, metastasis, or both at the time of eye symptoms. Conclusions: Paraneoplastic vitritis is primarily a disease of older age, with 67% of those affected older than 65 years. Ophthalmologists should maintain a high index of suspicion of paraneoplastic cause in bilateral posterior segment inflammat

Purpose: To evaluate the effect of intraoperative use of heavy liquid on retinal shift after retinal detachment repair. Design: Prospective, randomized study. Participants: Patients who underwent pars plana vitrectomy for macula-off rhegmatogenous retinal detachment were included in the current study. Methods: Patients were randomized into 2 groups: group A included patients in whom heavy liquid was used during the procedure and group B included patients in whom no heavy liquid was used. Group A and B patients were reviewed after 3 weeks and after 6 weeks, respectively, and fundus autofluorescence (fAf) images were obtained to visualize the retinal rotation. Main Outcome Measure: Postoperative macular shift, visualized with fAf. Results: A total of 50 eyes from 49 patients were included. Overall, retinal shift was observed in 17 patients (34%). Patients in whom heavy liquid was used during the procedure showed significantly less macular shift after surgery (P = 0.049). There was a strong association between retinal shift and postoperative symptoms of metamorphopsia. Ten of 17 patients with retinal shift reported distorted vision (P < 0.001). Conclusions: The use of intraoperative heavy liquid seems to be associated with lower occurrence of retinal shift after retinal detachment repair. (C) 2019 by the American Academy of Ophthalmology

The possibility to discriminate between different emission sources and between natural and anthropogenic contributions is a key issue for planning efficient air pollution reduction and mitigation strategies. Moreover, the knowledge of the particulate matter (PM) chemical composition for the different size fractions is recognized as increasingly important, in particular with respect to health effects of exposed population. This study is focused on the characterization of PM10 and PM2.5 main sources located in the Civitavecchia harbor-industrial area (Central Italy), namely a large coal-fired power plant, a natural gas power plant, the harbor area, the vehicular traffic (due to both the local traffic and the highway crossing the area) and small industrial activities. The approach was based on PM10/PM2.5 samples monthly collected for one year and a further relative chemical characterization of organic and inorganic fractions. Wind-select sensors, allowing a selective PM10 and PM2.5 sampling downwind to specific emission sources, were used for the overall sampling. This methodology manages to explain specific emission patterns and to assess the concentration levels of the micro pollutants emitted by local sources and particularly toxic for health. A descriptive statistical analysis of data was performed, also verifying the occurrence of legislative threshold exceedances. Moreover, in order to highlight the contribution of specific sources, the differences in the measured micro pollutants concentrations between wind directions, PM size fractions and sampling sites have been investigated, as well as the seasonal trends of pollutants concentrations. These results allow to highlight that the applied methodology represents a valid support in source apportionment studies.
