<P>Abstract. The Amazon Basin plays key roles in the carbon and water cycles, climate change, atmospheric chemistry, and biodiversity. It has already been changed significantly by human activities, and more pervasive change is expected to occur in the coming decades. It is therefore essential to establish long-term measurement sites that provide a baseline record of present-day climatic, biogeochemical, and atmospheric conditions and that will be operated over coming decades to monitor change in the Amazon region, as human perturbations increase in the future. The Amazon Tall Tower Observatory (ATTO) has been set up in a pristine rain forest region in the central Amazon Basin, about 150 km northeast of the city of Manaus. Two 80 m towers have been operated at the site since 2012, and a 325 m tower is nearing completion in mid-2015. An ecological survey including a biodiversity assessment has been conducted in the forest region surrounding the site. Measurements of micrometeorological and atmospheric chemical variables were initiated in 2012, and their range has continued to broaden over the last few years. The meteorological and micrometeorological measurements include temperature and wind profiles, precipitation, water and energy fluxes, turbulence components, soil temperature profiles and soil heat fluxes, radiation fluxes, and visibility. A tree has been instrumented to measure stem profiles of temperature, light intensity, and water content in cryptogamic covers. The trace gas measurements comprise continuous monitoring of carbon dioxide, carbon monoxide, methane, and ozone at five to eight different heights, complemented by a variety of additional species measured during intensive campaigns (e.g., VOC, NO, NO2, and OH reactivity). Aerosol optical, microphysical, and chemical measurements are being made above the canopy as well as in the canopy space. They include aerosol light scattering and absorption, fluorescence, number and volume size distributions, chemical composition, cloud condensation nuclei (CCN) concentrations, and hygroscopicity. In this paper, we discuss the scientific context of the ATTO observatory and present an overview of results from ecological, meteorological, and chemical pilot studies at the ATTO site. </P>

Damage control resuscitation

Evan Leibner,Mark Andreae,Samuel M. Galvagno Jr,Thomas Scalea 대한응급의학회 2020 Clinical and Experimental Emergency Medicine Vol.7 No.1

The United States Navy originally utilized the concept of damage control to describe the process of prioritizing the critical repairs needed to return a ship safely to shore during a maritime emergency. To pursue a completed repair would detract from the goal of saving the ship. This concept of damage control management in crisis is well suited to the care of the critically ill trauma patient, and has evolved into the standard of care. Damage control resuscitation is not one technique, but, rather, a group of strategies which address the lethal triad of coagulopathy, acidosis, and hypothermia. In this article, we describe this approach to trauma resuscitation and the supporting evidence base.

Palladium(II) Schiff Base Complexes Derived from Allylamine and Vinylaniline

Uh, Yoon-Seo,Zhang, Hai-Wen,Vogels, Christopher M.,Decken, Andreae,Westcott, Stephen A. Korean Chemical Society 2004 Bulletin of the Korean Chemical Society Vol.25 No.7

Condensation of salicylaldehyde $(2-HOC_6H_4C(O)H)$ with allylamine afforded the unsaturated salicylaldimine, $2-HOC_6H_4C(H)=NCH_2CH=CH_2$. Similar reactivity was observed with substituted salicylaldehydes. Further reaction of these Schiff bases with palladium acetate or $Na_2PdCl_4$ afforded complexes of the type $PdL_2$, where L = deprotonated Schiff base. The molecular structure of the parent salicylaldimine palladium complex $[trans-(2-OC_6H_4C(H)=NCH_2CH=CH_2)_2Pd]$ (1) was characterized by an X-ray diffraction study. Crystals of 1 were monoclinic, space group $P2_1/n,\;a\;=\;14.0005(9)\;{\AA},\;b\;=7.2964(5)\;{\AA},\;c\;=\;17.5103(12)\;{\AA},\;{\beta}\;=\;100.189(1)^{\circ}$, Z = 4. Analogous chemistry with 4-vinylaniline also gave novel palladium complexes containing a pendant styryl group. Crystals of $[trans-(2-HOC_6H_4C(H)=N-4-C_6H_4CH=CH_2)_2Pd]$ (4) were monoclinic, space group $P2_1/c$, a = 13.7710(14) ${\AA}$, b = 11.0348(11) ${\AA}$, c = 7.8192(8) ${\AA}$, ${\beta}\;=\;98.817(2)^{\circ}$, Z = 2.

Single-particle characterization of aerosols collected at a remote site in the Amazonian rainforest and an urban site in Manaus, Brazil

Wu, Li,Li, Xue,Kim, HyeKyeong,Geng, Hong,Godoi, Ricardo H. M.,Barbosa, Cybelli G. G.,Godoi, Ana F. L.,Yamamoto, Carlos I.,de Souza, Rodrigo A. F.,Pö,hlker, Christopher,Andreae, Meinrat O.,Ro, Chul Copernicus GmbH 2019 Atmospheric chemistry and physics Vol.19 No.2

<P><p><strong>Abstract.</strong> <span id='page1222'/>In this study, aerosol samples collected at a remote site in the Amazonian rainforest and an urban site in Manaus, Brazil, were investigated on a single-particle basis using a quantitative energy-dispersive electron probe X-ray microanalysis (ED-EPMA). A total of 23 aerosol samples were collected in four size ranges (0.25-0.5, 0.5-1.0, 1.0-2.0, and 2.0-4.0<span class='thinspace'></span><span class='inline-formula'>µ</span>m) during the wet season in 2012 at two Amazon basin sites: 10 samples in Manaus, an urban area; and 13 samples at an 80<span class='thinspace'></span>m high tower, located at the Amazon Tall Tower Observatory (ATTO) site in the middle of the rainforest, 150<span class='thinspace'></span>km northeast of Manaus. The aerosol particles were classified into nine particle types based on the morphology on the secondary electron images (SEIs) together with the elemental concentrations of 3162 individual particles: (i) secondary organic aerosols (SOA); (ii) ammonium sulfate (AS); (iii) SOA and AS mixtures; (iv) aged mineral dust; (v) reacted sea salts; (vi) primary biological aerosol (PBA); (vii) carbon-rich or elemental carbon (EC) particles, such as soot, tarball, and char; (viii) fly ash; and (ix) heavy metal (HM, such as Fe, Zn, Ni, and Ti)-containing particles. In submicron aerosols collected at the ATTO site, SOA and AS mixture particles were predominant (50<span class='thinspace'></span>%-94<span class='thinspace'></span>% in relative abundance) with SOA and ammonium sulfate comprising 73<span class='thinspace'></span>%-100<span class='thinspace'></span>%. In supermicron aerosols at the ATTO site, aged mineral dust and sea salts (37<span class='thinspace'></span>%-70<span class='thinspace'></span>%) as well as SOA and ammonium sulfate (28<span class='thinspace'></span>%-58<span class='thinspace'></span>%) were abundant. PBAs were observed abundantly in the PM<span class='inline-formula'>₂₋₄</span> fraction (46<span class='thinspace'></span>%), and EC and fly ash particles were absent in all size fractions. The analysis of a bulk PM<span class='inline-formula'>_0.25−0.5</span> aerosol sample from the ATTO site using Raman microspectrometry and attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) showed that ammonium sulfate, organics, and minerals are the major chemical species, which is consistent with the ED-EPMA results. In the submicron aerosols collected in Manaus, either SOA and ammonium sulfate (17<span class='thinspace'></span>%-80<span class='thinspace'></span>%) or EC particles (6<span class='thinspace'></span>%-78<span class='thinspace'></span>%) were dominant depending on the samples. In contrast, aged mineral dust, reacted sea salt, PBA, SOA, ammonium sulfate, and EC particles comprised most of the supermicron aerosols collected in Manaus. The SOA, ammonium sulfate, and PBAs were mostly of a biogenic origin from the rainforest, whereas the EC and HM-containing particles were of an anthropogenic origin. Based on the different contents of SOA, ammonium sulfate, and EC particles among the samples collected in Manaus, a considerable influence of the rainforest over the city was observed. Aged mineral dust and reacted sea-salt particles, including mineral dust mixed with sea salts probably during long-range transatlantic transport, were abundant in the supermicron fractions at both sites. Among the aged mineral dust and reacted sea-salt particles, sulfate-containing ones outnumbered those containing nitrates and sulfate<span class='thinspace'></span><span class='inline-formula'>+</span><span class='thinspace'></span>nitrate in the ATTO samples. In contrast, particles containing sulfate<span class='thinspace'></span><span class='inline-formula'>+</span><span class='thinspace'></span>nitrate were comparable in number to particles containing sulfate only in the Manaus samples, indicating

Extracranial systemic antitumor response through the abscopal effect induced by brain radiation in a patient with metastatic melanoma

Mark A. D’Andrea,G. Kesava Reddy, 대한방사선종양학회 2019 Radiation Oncology Journal Vol.37 No.4

The abscopal effect is a term that has been used to describe the phenomenon in which localized radiation therapy treatment of a tumor lesion triggers a spontaneous regression of metastatic lesion(s) at a non-irradiated distant site(s). Radiation therapy induced abscopal effects are believed to be mediated by activation and stimulation of the immune system. However, due to the brain’s distinctive immune microenvironment, extracranial abscopal responses following cranial radiation therapy have rarely been reported. In this report, we describe the case of 42-year-old female patient with metastatic melanoma who experienced an abscopal response following her cranial radiation therapy for her brain metastasis. The patient initially presented with a stage III melanoma of the right upper skin of her back. Approximately 5 years after her diagnosis, the patient developed a large metastatic lesion in her upper right pectoral region of her chest wall and axilla. Since the patient’s tumor was positive for BRAF and MEK, targeted therapy with dabrafenib and trametinib was initiated. However, the patient experienced central nervous system (CNS) symptoms such as headache and disequilibrium and developed brain metastases prior to the start of targeted therapy. The patient received radiation therapy to a dose of 30 Gy delivered in 15 fractions to her brain lesions while the patient was on dabrafenib and trametinib therapy. The patient’s CNS metastases improved significantly within weeks of her therapy. The patient’s non-irradiated large extracranial chest mass and axilla mass also shrank substantially demonstrating the abscopal effect during her CNS radiation therapy. Following radiation therapy of her residual chest lesions, the patient was disease free clinically and her CNS lesions had regressed. However, when the radiation therapy ended and the patient continued her targeted therapy alone, recurrence outside of her previously treated fields was noted. The disease recurrence could be due to the possibility of developing BRAF resistance clones to the BRAF targeted therapy. The patient died eventually due to wide spread systemic disease recurrence despite targeted therapy

Travel Books and Urban Identity. British Travellers in Messina, 1770-1815: A Preliminary Study

( Diletta D`andrea ) 부산외국어대학교 지중해연구소 2014 The Mediterranean Review Vol.7 No.1

Patrick Brydone`s Tour through Sicily and Malta, first published in 1773, was a primary guide-book for all those travellers who reached Sicily from Northern Europe for the first time. Thanks to Brydone`s enthusiastic survey, Sicily and especially Messina became part of the itinerary of the Italian Grand Tour. Regular flows of travellers arrived. During the Napoleonic Wars and mostly during the British Decade (1806-1815) in Sicily, when His Majesty`s military forces occupied the Bourbons` island and protected it from a possible French invasion, Messina became the site of the British military head-quarters; at the same time, its port was either the final destination or the starting point for many travellers, whose striking descriptions helped build a new identity for Messina and put the city among the most favoured destinations of the Grand Tour in the Mediterranean. A strong connection was then created between the Sicilian town and England, a connection that lasted over ‘the long nineteenth century’.

An accessory submandibular gland is a rare variation. As such, there is limited literature regarding the embryology, anatomy, variations, clinical imaging, and pathology of the accessory submandibular gland. In this article, we review the existing literature on the accessory submandibular gland from clinical and anatomical perspectives. The goal of this review is to provide comprehensive knowledge of this variation which can be useful for oral and maxillofacial/head and neck surgeons, radiologists, and anatomists. Within this review, the embryologic origin as well as the anatomy of the accessory submandibular gland is detailed. Several imaging modalities which can be used to visualize the accessory submandibular gland are outlined as well as its variations. Lastly, this review investigates several reported clinical considerations regarding the accessory submandibular gland including sialoliths, Wharton’s duct obstruction, and pleomorphic adenoma.

Purpose: The aim of this study was to evaluate the efficacy of collagenase Clostridium histolyticum (CCH) in patients with Peyronie’s disease (PD) suffering from atypical deformities. Materials and Methods: We retrospectively collected data of patients with atypical penile curvature (PC) secondary to PD. All patients underwent a modified treatment protocol, consisting of 3 intralesional injections of 0.9 mg of CCH performed at 4-week intervals at the point of maximum PC. Patients were instructed to follow a strict routine, involving daily modeling of erect penis and stretching at the urinary toilette time, two minutes each. Success was defined as a decrease in PC of ≥20° from baseline. Results: Sixty-five patients were included in the analysis. Median age was 59.0 years (interquartile range [IQR], 53.0 to 63.0 years), median curvature 40.0° (IQR, 30.0° to 45.0°) median duration of the disease 12.0 years (IQR, 6.5 to 24.0 years). Fiftythree patients (81.54%) had ventral PC, 7 (10.77%) hourglass PC, and 5 (7.69%) shortening PC. Median changes of PC were -20.0 (IQR, -20.0 to -10.0; p<0.01) in ventral PC, -20.0 (IQR, -20.0 to 0; p<0.01) in hourglass and -15.0 (IQR, -15.0 to -15.0; p<0.01) in shortening PC. At Kruscal–Wallis test, significant differences between groups were not found. The rate of PC success was 56.60% (30/53) in ventral PC, 57.14% (4/7) in hourglass and 20.00% (1/5) in shortening PC (p=0.29). Treatment success was not influenced by characteristics of curvature (odds ratio=0.66; p=0.20). Conclusions: CCH intralesional injections could represent an effective therapeutic option for the conservative management of patients with atypical PC.
