Evolution of the concentration of phenolic compounds in cachaça during aging in an oak (Quercus sp.) barrel

Cachaça is a traditional and popular Brazilian drink obtained by distilling fermented sugar cane juice. Among the steps involved in its production, natural aging in wood containers for a certain period of time can lead to alterations in the chemical composition, aroma, flavor and color of the beverage. The present work sought to determine the concentration of phenolic compounds after different periods of aging of the cachaça in an oak (Quercus sp.) barrel. Periodic collections during the aging period were performed, and thirteen selected phenolic compounds were determined by high performance liquid chromatography with a diode-array detector (HPLC-DAD). A progressive increase in the concentration of the compounds analyzed was observed, with syringaldehyde and gallic acid as the compounds encountered in the highest concentration.

Proposed Updates to the List of Recognised Species of Cetaceans

Addition of three species to the list is recommended based on recent literature. (Orcaella brevirostris) has been split into the Irrawaddy dolphin (O. brevirostris) and the Australian snubfin dolphin (O. heinsohni). Sotalia fluviatilis has been split into the riverine tucuxi (S. fluviatilis) and the marine "costero" (S. guianensis). Evidence to support both of these splits is convincing, and we recommend that they be recognized in the list. The existence of the Bryde's-whale-like species described in 2003 as Balaenoptera omurai has been confirmed with additional genetic (nuclear) data. While the species clearly exists, the nomenclature is still unsettled because the genetic identity of the holotype specimen of Balaenoptera edeni has not yet been determined. However, the name B. omurai is gaining wide usage in application to the new species, and we propose that it be used provisionally by the Scientific Committee pending the genetic identification of the B. edeni holotype. We recommend that India be urged to facilitate the identification. We recommend continued use of the name Balaenoptera edeni provisionally for both the "ordinary" large form and the small coastal form, recognizing that further genetic and morphological research may justify recognition of two species: B. brydei and B. edeni. We also recommend that any new specimen be referred to B. omurai only after its mtDNA has been sequenced and found to support the identification.

Patients on the Waiting List for Liver Transplantation: Caregiver Burden and Stress

Over the last few decades, informal caregivers of patients with chronic diseases have received more attention, and there is a growing volume of studies demonstrating high rates of burden, stress, and mental disorders in this group of individuals. The objective of this study was to evaluate the burden, stress, and psychosocial characteristics of informal caregivers of liver transplantation candidates. Participants were assessed by individual evaluations with the following instruments: a semi-structured interview, the Caregiver Burden Scale, the Inventario de Sintomas de Stress para Adultos de Lipp, and the Beck Depression Inventory. The Mann-Whitney test was used for statistical analysis with a significance level of 0.05. The characteristics of the study group (n = 61) were similar to those of groups in other studies with respect to gender (82% were women), kinship (64% were spouses), and age (the mean age was 47.6 years). The main stressors identified by the participants were as follows: doubts about ways to react in a crisis or in emergency situations (42.6%), mood swings of the patient (29.5%), and care involving food and medications (27.9%). Approximately 25% of the caregivers reported that they felt unprepared to adequately perform their roles. Data analysis indicated a greater burden overall on caregivers when the patient`s Model for End-Stage Liver Disease score was greater than or equal to 15 points (P = 0.041). Furthermore, caregivers of patients with alcoholic liver disease showed higher depression (P = 0.034) and overall burden scores (P = 0.031) versus caregivers of patients with liver disease due to other etiologies. In conclusion, the participants showed significantly high levels of burden, stress, and depression. Support measures and caregiver preparation should be implemented by health care providers.

New Brazilian Floristic List Highlights Conservation Challenges

A comprehensive new inventory of Brazilian plants and fungi was published just in time to meet a 2010 Convention on Biological Diversity target and offers important insights into this biodiversity's global significance. Brazil is the home to the world's richest flora (40,989 species; 18,932 endemic) and includes two of the hottest hotspots: Mata Atlantica (19,355 species) and Cerrado (12,669 species). Although the total number of known species is one-third lower than previous estimates, the absolute number of endemic vascular plant species is higher than was previously estimated, and the proportion of endemism (56%) is the highest in the Neotropics. This compilation serves not merely to quantify the scale of the challenge faced in conserving Brazil's unique flora but also serves as a key resource to direct action and monitor progress. Similar efforts by other megadiverse countries are urgently required if the 2020 targets of the Convention on Biological Diversity and the Global Strategy for Plant Conservation are to be attained.

The role of myocardial scintigraphy in the assessment of cardiovascular risk in patients with end-stage chronic kidney disease on the waiting list for renal transplantation

The usefulness of stress myocardial perfusion scintigraphy for cardiovascular (CV) risk stratification in chronic kidney disease remains controversial. We tested the hypothesis that different clinical risk profiles influence the test. We assessed the prognostic value of myocardial scintigraphy in 892 consecutive renal transplant candidates classified into four risk groups: very high (aged epsilon 50 years, diabetes and CV disease), high (two factors), intermediate (one factor) and low (no factor). The incidence of CV events and death was 20 and 18, respectively (median follow-up 22 months). Altered stress testing was associated with an increased probability of cardiovascular events only in intermediate-risk (one risk factor) patients [30.3 versus 10, hazard ratio (HR) 2.37, confidence interval (CI) 1.693.33, P 0.0001]. Low-risk patients did well regardless of scan results. In patients with two or three risk factors, an altered stress test did not add to the already increased CV risk. Myocardial scintigraphy was related to overall mortality only in intermediate-risk patients (HR 2.8, CI 1.55.1, P 0.007). CV risk stratification based on myocardial stress testing is useful only in patients with just one risk factor. Screening may avoid unnecessary testing in 60 of patients, help stratifying for risk of events and provide an explanation for the inconsistent performance of myocardial scintigraphy.

Ectomycorrhizae of sessile oak (Quercus petraea (Matt.) Liebl.)

Investigations were performed during the years 1999 to 2001 on a limed and unlimed plot within a high-elevated sessile oak forest. The oak forest (with 90 years old European beech at the understorey) was 170 to 197 years old. It is located at forest district Merzalben, location 04/0705, which is situated in the Palatinate Forest in south-west Germany. Liming was performed in December 1988 when 6 tons/ha of powdered Dolomite were brought up by the forestry department. Liming was performed to counteract the effects of soil acidification (pH(H2O) at Horizon A (0-10 cm): 3.9), which is induced by long-term (anthropogenic) acidic cloud cover and precipitation. Potentially toxic Al3+ ions, which become solubilized below pH 5, were suspected to be responsible for forest dieback and sudden death of the mature oaks. The most logical entry point for these toxic ions was suspected to occur in the highly absorptive region of the ectomycorrhizae (fungal covered root tips). However, the diversity and abundance of oak-ectomycorrhizal species and their actual roles in aluminum translocation (or blockage) were unknown. It was hypothesized that the ectomycorrhizae of sessile oaks in a limed forest would exhibit greater seasonal diversity and abundance with less evidence of incorporated aluminum than similar oak ectomycorrhizae from unlimed soils. To test this hypothesis, 12 oaks in the limed plot and 12 in an adjacent unlimed plot were selected. Each spring and fall for 2 years (1999 & 2000), 2 sets of soil cylinders (9.9 cm dia.) were extracted from Horizon A (0-10 cm), Horizon B (30-40 cm) and Horizon C (50-60 cm depth) at a distance of 1 meter from each tree base. Roots were extracted from each probe by gentle sieving and rinsing. Soil samples were retained for pH (H2O, CaCl2, and KCl) and moisture analysis. One set of roots was sorted by size and air-dried for biomass analysis. The finest mycorrhizal roots of this set were used for bound and unbound (cytosolic) mineral [Al, Ca, Mg, K, Na, Mn, S, Zn, Fe, Cd and Pb] analysis (by Landwirtschaftliche Untersuchungs- und Forschungsanstalt Rheinland Palatinate (LUFA)). Within 7 days of collection, the mycorrhizal tips from the second set of probes were excised, sorted, identified (using Agerer’s Color Atlas), counted and weighed. Seasonal diversity and abundance was characterized for 50 of the 93 isolates. The location and relative abundance of Al within the fungal and root cell walls was characterized for 68 species using 0.01% Morin dye and fluorescence microscopy. Morin complexes with Al to produce an intense yellow fluorescence. The 4 most common species (Cenococcum geophilum, Quercirhiza fibulocsytidiata, Lactarius subdulcis, Piceirhiza chordata) were prepared for bound Al, Ca, Fe and K mineral analysis by LUFA. The unlimed and limed plots were then compared. Only 46 of the 93 isolated ectomycorrhizal species had been previously associated with oaks in the literature. Mycorrhizal biomass was most abundant in Horizon A, declining with depth, drought and progressive soil acidification. Mycorrhizae were most diverse (32 species) in the limed plot, but individual species abundance was low (R Selection) in comparison to the unlimed plot, where there were fewer species (24) but each species present was abundant (K Selection). Liming increased diversity and altered dominance hierarchy, seasonal distributions and succession trends of ectomycorrhizae at all depths. Despite an expected reduction in Al content, the limed ectomycorrhizae both qualitatively (fluorescence analysis) and quantitatively (mineral analysis) contained more bound Al, especially so in Horizon A. The Al content qualitatively and quantitatively increased with depth in the unlimed and limed plots. The bound Al content fluctuated between 4000-and 20000 ppm while the unbound component was consistently lower (4 -14 ppm). The relative amount of unbound Al declined upon liming implying less availability for translocation to the crown area of the trees. This correspouds with the findings of good crown appearance and lower tree mortality in the limed zone. Each ectomycorrhizal species was unique in its ability to block, sequester (hold) or translocate Aluminum. In several species, Al uptake varied with changes in moisture, pH, depth and liming. According to the fluorescence study, about 48% of the isolated ectomycorrhizal species blocked and/or sequestered (held) Al in their mantle and/or Hartig net walls, qualitatively lowering bound Al in the adjacent root cell walls. Generally, if Al was more concentrated in the fungal walls, it was less evident in the cortex and xylem and conversely, if Al was low or absent from the fungal walls it was frequently more evident in the cortex and xylem.

Proposta di traduzione di un capitolo di The To-Do List di Mike Gayle

Scopo principale del seguente elaborato è quello di fornire una possibile traduzione di un capitolo dell’opera di Mike Gayle, The To-Do List. Al fine di contestualizzare e rendere più comprensibile, specie per un lettore italiano, la proposta di traduzione in questione, verranno descritti dapprima l’autore ed il genere letterario al quale appartiene il libro, quindi la trama del libro stesso. Seguirà il commento della traduzione, nel quale si evidenzieranno alcuni degli elementi particolarmente difficili da rendere in italiano – talvolta dal punto di vista lessicale, più spesso dal punto di vista culturale. La scelta di affrontare l’opera di Gayle nasce soprattutto dall’interesse verso uno dei corsi svolti all’università, grazie al quale ho avuto l’occasione di scoprire, in lingua inglese, il genere letterario comunemente chiamato Chick Lit; The To-Do List, che appartiene a quella che potremmo definire come “Chick Lit maschile”e che presenta moltissimi riferimenti alla cultura britannica, rappresentava la fonte perfetta per mettermi alla prova ed effettuare una traduzione che fosse, oltre che fedele al testo originale, comprensibile e immediata per un ipotetico lettore italiano.
