Do Terrestrial Tank Bromeliads in Brazil Create Safe Sites for Palm Establishment or Act as Natural Traps for Its Dispersed Seeds ?

This study shows for the first time that terrestrial tank bromeliads from Brazilian restinga can act as natural traps for dispersed palm Euterpe edulis seeds. Such bromeliads, which are shade intolerant, gain benefits by limiting palm recruitment since they hinder canopy formation and, consequently, increase luminosity over its aggregates.

Repetition of Suicide Attempts Data from Emergency Care Settings in Five Culturally Different Low- and Middle-Income Countries Participating in the WHO SUPRE-MISS Study

Background: Attempted suicide is a strong risk factor for subsequent suicidal behaviors. Innovative strategies to deal with people who have attempted suicide are needed, particularly in resource-poor settings. Aims: To evaluate a brief educational intervention and periodic follow-up contacts (BIC) for suicide attempters in five culturally different sites (Campinas, Brazil; Chennai, India; Colombo, Sri Lanka; Karaj, Islamic Republic of Iran; and Yuncheng, People's Republic of China) as part of the WHO Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS). Methods: Among the 1,867 suicide attempters enrolled in the emergency departments of the participating sites, 922 (49.4%) were randomly assigned to a brief intervention and contact (BIC) group and 945 (50.6%) to a treatment as usual (TAU) group. Repeated suicide attempts over the 18 months following the index attempt - the secondary outcome measure presented in this paper - were identified by follow-up calls or visits. Subsequent completed suicide - the primary outcome measure has been reported in a previous paper. Results: Overall, the proportion of subjects with repeated suicide attempts was similar in the BIC and TAU groups (7.6% vs. 7.5%, chi(2) = 0.013; p = .909), but there were differences in rates across the five sites. Conclusions: This study from five low-and middle-income countries does not confirm the effectiveness of brief educational intervention and follow-up contacts for suicide attempters in reducing subsequent repetition of suicide attempts up to 18 months after discharge from emergency departments.

Safe by a Mile

Charlie Metro's career runs the gamut of the specialties found in baseball-player, coach, manager, scout, inventor. Metro has lived baseball at every level from the Great Depression to today's multimillion dollar contracts. One of a kind, Metro's life mirrors the astounding changes in the game as well as in the nation. Metro's tale is full of heart and a wealth of anecdotes, the result of a fascinating life and a true love of the game. Charlie Metro was born Charles Moreskonich in Nanty-Glo, Pennsylvania, in 1919. He played in the major leagues from 1943 to 1945 with the Detroit Tigers and the Philadelphia Athletics. He managed for parts of two seasons, with the 1962 Cubs and the 1970 Kansas City Royals. He also coached the 1965 Chicago White Sox and the 1982 Oakland Athletics. Although he had far longer service in the minor leagues, he will probably be best remembered as one of the great scouts and teachers in baseball history. This excerpt includes the Introduction and Chapter 1, "Hookey from High School."

Is it safe to utilize in vitro reconstituted human oral epithelium? An oncogenetic pathway study

Cell therapy is a therapeutic strategy used to replace or repair damaged tissue. The epithelium transplantation of cultivated keratinocytes has been applied to several modalities of reconstruction, like oral, urethra and ocular surface. Life and death signals work coordinately to ensure cellular quality control and the viability of an organism. The aim of this study is to verify that culture conditions did not induce genetic mutations through the analysis of the key genes: pAKT, Pten, p53 and MDM2 and investigate the presence of the related proteins in human oral keratinocytes obtained by primary culture and in vitro cultivated. Formalin fixed and paraffin embedded tissues from the oral cavity were utilized as control for normal expression of the related markers and two oral squamous cell carcinoma cell lines provided the expression pattern of the proposed markers in the event of cellular transformation. Akt, PTEN, p53 and MDM2 immunohistochemistry and Western-Blotting analyzes were performed. The results showed the expression levels and intracellular localizations of the four proteins evaluated. These analyzes confirmed that the produced in vitro epithelium is bio-compatible for its utilization as reconstruction and reparatory tissue, however further analyses and additional research on other biomarkers should be performed to analyse the long term engraftment of transplantable primary culture of oral keratinocytes and the long term resistance to cellular transformation.

Standard surgical treatment for benign prostatic hyperplasia is safe for patients over 75 years: Analysis of 100 cases from a high-volume urologic center

OBJECTIVES: In this study, we aimed to determine the complications of standard surgical treatments among patients over 75 years in a high-volume urologic center. METHODS: We analyzed 100 consecutive patients older than 75 years who had undergone transurethral prostatic resection of the prostate or open prostatectomy for treatment of benign prostatic hyperplasia from January 2008 to March 2010. We analyzed patient age, prostate volume, prostate-specific antigen level, international prostatic symptom score, quality of life score, urinary retention, co-morbidities, surgical technique and satisfaction with treatment. RESULTS: Median age was 79 years. Forty-eight patients had undergone transurethral prostatic resection of the prostate, and 52 had undergone open prostatectomy. The median International Prostatic Symptom Score was 20, the median prostate volume was 83 g, 51% were using an indwelling bladder catheter, and the median prostate-specific antigen level was 5.0 ng/ml. The most common comorbidities were hypertension, diabetes and coronary disease. After a median follow-up period of 17 months, most patients were satisfied. Complications were present in 20% of cases. The most common urological complication was urethral stenosis, followed by bladder neck sclerosis, urinary fistula, late macroscopic hematuria and persistent urinary incontinence. The most common clinical complication was myocardial infarction, followed by acute renal failure requiring dialysis. Incidental carcinoma of the prostate was present in 6% of cases. One case had urothelial bladder cancer. CONCLUSIONS: Standard surgical treatments for benign prostatic hyperplasia are safe and satisfactory among the elderly. Complications are infrequent, and urethral stenosis is the most common. No clinical variable is associated with the occurrence of complications.

Design di un sistema di fault detection per un'architettura fail-safe di attuazione delle superfici di controllo di un UAV

In questo lavoro di tesi si affronta una delle problematiche che si presentano oggi nell'impiego degli APR (Aeromobili a Pilotaggio Remoto): la gestione della safety. Non si può più, in altri termini, negare che tali oggetti siano parte integrante dello spazio aereo civile. Proprio su questo tema recentemente gli enti regolatori dello spazio aereo stanno proiettando i loro sforzi al fine di stabilire una serie di regolamenti che disciplinino da una parte le modalità con cui questi oggetti si interfacciano con le altre categorie di velivoli e dall'altra i criteri di idoneità perché anche essi possano operare nello spazio aereo in maniera sicura. Si rende quindi necessario, in tal senso, dotare essi stessi di un sufficiente grado di sicurezza che permetta di evitare eventi disastrosi nel momento in cui si presenta un guasto nel sistema; è questa la definizione di un sistema fail-safe. Lo studio e lo sviluppo di questa tipologia di sistemi può aiutare il costruttore a superare la barriera oggi rappresentata dal regolamento che spesso e volentieri rappresenta l'unico ostacolo non fisico per la categoria dei velivoli unmanned tra la terra e il cielo. D'altro canto, al fine di garantire a chi opera a distanza su questi oggetti di avere, per tutta la durata della missione, la chiara percezione dello stato di funzionamento attuale del sistema e di come esso può (o potrebbe) interagire con l'ambiente che lo circonda (situational awarness), è necessario dotare il velivolo di apparecchiature che permettano di poter rilevare, all'occorrenza, il malfunzionamento: è questo il caso dei sistemi di fault detection. Questi due fondamentali aspetti sono la base fondante del presente lavoro che verte sul design di un ridotto ma preponderante sottosistema dell'UAV: il sistema di attuazione delle superfici di controllo. Esse sono, infatti, l'unico mezzo disponibile all'operatore per governare il mezzo nelle normali condizioni di funzionamento ma anche l'ultima possibilità per tentare di evitare l'evento disastroso nel caso altri sottosistemi siano chiaramente fuori dalle condizioni di normale funzionamento dell'oggetto.
