Opportunistic Pathogenic Bacteria Colonize Thorns of Native Rio Grande Valley Plants

Thorns serve as mechanical defenses of plants against herbivory. However, plant thorns harbor microorganisms that are potentially pathogenic. These pathogens may be transferred to herbivores and other animals and provide an additional defense for the plants. Thorns from 5 plant species native to the Rio Grande Valley of South Texas were collected and used to isolate bacteria colonizing the thorn surface. Thorns, leaves and stems of plants were visualized using Scanning Electron Microscopy (SEM) to observe any bacteria on the plant surface. Isolated bacteria were tested for their ability to grow in aerobic versus anaerobic environments, to produce hemolysis, carbon source utilization, and were gram-stained. Bacteria were identified by sequencing of the 16S rRNA gene. A total of 69 pure cultures were obtained of which 61 were positively identified. The majority of the bacteria were gram-positive and facultative (i.e., able to grow both aerobically and anaerobically). Many (23%) were hemolytic suggesting that they were opportunistic blood-borne pathogens. All isolated organisms metabolized a collection of 31 tested organic substrates and metabolic activity was observed to be more efficient among anaerobically-isolated microorganisms compared to microorganisms isolated aerobically. SEM revealed that bacteria were found on the thorn surface but also on the stems and leaves of the plants. Identification using the 16S rRNA gene revealed the presence of 10 species representing 7 genera. The most commonly identified organisms were Bacillus cereus, Serratia marcescens, and Pseudomonas aeruginosa, all of which are opportunistic pathogens

The first 8-13 micron spectra of globular cluster red giants: circumstellar silicate dust grains in 47 Tucanae (NGC 104)

We present 8-13 micron spectra of eight red giants in the globular cluster 47 Tucanae (NGC 104), obtained at the European Southern Observatory 3.6m telescope. These are the first mid-infrared spectra of metal-poor, low-mass stars. The spectrum of at least one of these, namely the extremely red, large-amplitude variable V1, shows direct evidence of circumstellar grains made of amorphous silicate.Comment: Accepted for publication in Astronomy and Astrophysics, 5 page

Critical Issues for Psychiatric Medication Shared Decision Making With Youth and Families

This is the publisher's version, also found here: http://doi.org/10.1606/1044-3894.4135The primary aims of this article are to describe the current context for youth shared decision making (SDM) within the U.S. children’s mental health system and to identify important considerations for the development of this approach as a research and service domain. The notion is substantiated in the literature that participation in treatment decisions can prepare youth for making their own decisions as adults, can be therapeutic, and can have positive effects on their self-confidence and self-esteem. Still, the complex youth–family–provider dynamic raises important issues that need to be addressed before SDM can be successfully implemented

Insights From the Histopathologic Analysis of Acquired and Genetic Thoracic Aortic Aneurysms and Dissections

OBJECTIVE: The purpose of this study was to apply contemporary consensus criteria developed by the Society for Cardiovascular Pathology and the Association for European Cardiovascular Pathology to the evaluation of aortic pathology, with the expectation that the additional pathologic information may enhance the understanding and management of aortic diseases. METHODS: A scoring system was applied to ascending aortic specimens from 42 patients with heritable thoracic aortic disease and known genetic variations and from 86 patients from a single year, including patients with known genetic variations (n = 12) and patients with sporadic disease (n = 74). RESULTS: The various types of lesions of medial degeneration and the overall severity of medial degeneration overlapped considerably between those patients with heritable disease and those with sporadic disease; however, patients with heritable thoracic aortic disease had significantly more overall medial degeneration (P = .004) and higher levels of elastic fiber fragmentation (P = .03) and mucoid extracellular matrix accumulation (P = .04) than patients with sporadic thoracic aortic disease. Heritable thoracic aortic disease with known genetic variation was more prevalent in women than in men (27.2% vs 9.8%; P = .04), and women had more severe medial degeneration than men (P = .04). Medial degeneration scores were significantly lower for patients with bicuspid aortic valves than for patients with tricuspid aortic valves (P = .03). CONCLUSION: The study\u27s findings indicate considerable overlap in the pattern, extent, and severity of medial degeneration between sporadic and hereditary types of thoracic aortic disease. This finding suggests that histopathologic medial degeneration represents the final common outcome of diverse pathogenetic factors and mechanisms
