The community capacity curve applied to reforestation: a framework to support success.

Community involvement is critical for the success of many interventions designed to promote reforestation. To secure this involvement, it helps to recognize that communities are heterogenous both within and among themselves and possess diverse mixes of livelihood assets required to implement reforestation. We explore the relationship between livelihood assets and reforestation success and outline a conceptual model that we call the community capacity curve (CCC) applied to reforestation.

A 50-Year-Old Man With a History of Recurrent Exudative Right-Sided Pleural Effusion.

In this case report, we describe a 50-year-old man who presented to our facility for a second opinion after a year-long history of recurrent and now persistent right-sided exudative pleural effusion. On review of previous records, negative findings were seen in microbiological studies, including acid-fast bacilli, cytology, flow cytometry, and pleural biopsy using video-assisted thoracoscopy. On transthoracic echocardiography performed during our evaluation, the expected respiratory variations across the mitral and tricuspid valves were not appreciated.

Sustained timber yield claims, considerations, and tradeoffs for selectively logged forests.

What is meant by sustainability depends on what is sustained and at what level. Sustainable forest management, for example, requires maintenance of a variety of values not the least of which is sustained timber yields (STYs). For the 1 Bha of the world's forests subjected to selective or partial logging, failure to maintain yields can be hidden by regulatory requirements and questionable auditing practices such as increasing the number of commercial species with each harvest, reducing the minimum size at which trees can be harvested and accepting logs of lower quality.

Evaluation of Zika rapid tests as aids for clinical diagnosis and epidemic preparedness.

Background: Development and evaluation of diagnostics for diseases of epidemic potential are often funded during epidemics, but not afterwards, leaving countries unprepared for the next epidemic. United Nations Children's Emergency Fund (UNICEF) partnered with the United States Agency for International Development (USAID) to address this important gap by investing in an advance purchase commitment (APC) mechanism to accelerate the development and evaluation of Zika rapid diagnostic tests (RDTs) for case detection and surveillance. This paper describes the performance evaluation of five Zika RDTs eligible for procurement.

The forgotten urinalysis: an integral part of unmasking thrombophilia.

A 43-year-old female presented with flank pain of two days duration. She had been admitted previously for bilateral lower extremity edema which had not improved with diuresis. Abdominal Imaging showed left ovarian vein thrombosis and left renal vein thrombosis extending into the IVC.

Cutting Edge: Transcriptional Profiling Reveals Multifunctional and Cytotoxic Antiviral Responses of Zika Virus-Specific CD8 T Cells.

Zika virus (ZIKV) constitutes an increasing public health problem. Previous studies have shown that CD8 T cells play an important role in ZIKV-specific protective immunity. We have previously defined antigenic targets of the ZIKV-specific CD8 T cell response in humans.

Opportunity costs of carbon sequestration in a forest concession in central Africa.

Background: A large proportion of the tropical rain forests of central Africa undergo periodic selective logging for timber harvesting. The REDD+ mechanism could promote less intensive logging if revenue from the additional carbon stored in the forest compensates financially for the reduced timber yield.

Results: Carbon stocks, and timber yields, and their associated values, were predicted at the scale of a forest concession in Gabon over a project scenario of 40 yr with reduced logging intensity.

Improving credibility and transparency of conservation impact evaluations through the partial identification approach.

The fundamental challenge of evaluating the impact of conservation interventions is that researchers must estimate the difference between the outcome after an intervention occurred and what the outcome would have been without it (counterfactual). Because the counterfactual is unobservable, researchers must make an untestable assumption that some units (e.g.

Ecto-nucleotidases activities in the contents of ovarian endometriomas: potential biomarkers of endometriosis.

Endometriosis, defined as the growth of endometrial tissue outside the uterus, is a common gynecologic condition affecting millions of women worldwide. It is an inflammatory, estrogen-dependent complex disorder, with broad symptomatic variability, pelvic pain, and infertility being the main characteristics. Ovarian endometriomas are frequently developed in women with endometriosis.

Changes in hospitalizations for pneumonia after universal vaccination with pneumococcal conjugate vaccines 7/13 valent and haemophilus influenzae type b conjugate vaccine in a Pediatric Referral Hospital in Uruguay.

Background: In 1994, Uruguay included Haemophilus influenzae b (Hib) conjugated vaccine in a 3 + 1 schedule. In March 2008, 7-valent pneumococcal conjugate vaccines (PCV7) was included in a 2 +1 schedule. In 2010, 13-valent PCV replaced PCV7.

Certified and uncertified logging concessions compared in Gabon: changes in stand structure, tree species, and biomass.

Forest management certification is assumed to promote sustainable forest management, but there is little field-based evidence to support this claim. To help fill this gap, we compared a Forest Stewardship Council (FSC)-certified with an adjacent uncertified, conventionally logged concession (CL) in Gabon on the basis of logging damage, above-ground biomass (AGB), and tree species diversity and composition. Before logging, we marked, mapped, and measured all trees >10 cm dbh in 20 and twelve 1-ha permanent plots in the FSC and CL areas, respectively.

Cellular infiltration and cytokine expression correlate with fistulizing state in Crohn's disease.

The purpose of this study was to determine the degree of infiltration of different cell subpopulations (tissue dendritic macrophages, T-helper cells, cytotoxic T lymphocytes, monocytes, neutrophils, and B cells) and the expression of the cytokines interleukin-12 (IL-12) and tumor necrosis factor alpha (TNF-α) in inflamed and noninflamed resected tissues from Crohn's disease (CD) and non-CD patients. Twenty-one resected full-thickness intestinal tissue specimens representing 13 subjects (8 CD and 5 non-CD patients) were included in this study. Sections of 20 μm in thickness were cut and then stained using immunohistochemistry.

Evaluation of a rapid water-surface sweeping method to accurately estimate numbers of Aedes aegypti (Diptera: Culicidae) late larval stages in large water-storage containers: comparison with pupal estimates.

Introduction: Since the methodologies used to calculate Stegomyia indices have been shown to be inadequate for assessing the risk of dengue virus transmission and targeting Aedes aegypti control strategies, new surveillance methods are needed.

Objective: To evaluate the water-surface sweeping method in combination with calibration factors to estimate the total number of Ae. aegypti late larval stages (L3/L4) in large water-storage containers at different temperatures at which transmission of dengue virus occurs.

Stem responses to damage: the evolutionary ecology of Quercus species in contrasting fire regimes.

* The ability of tree stems to recover from damage is critical for tree survival and may explain species distributions across disturbance regimes. Two primary responses to stem damage, decay compartmentalization and wound closure, act in concert to limit decay and pathogen spread. A previous study demonstrated a tradeoff between wound responses that varied with anatomical traits, but its wide taxonomic range made it hard to analyze responses in an evolutionary context.

Genome sequence alterations detected upon passage of Burkholderia mallei ATCC 23344 in culture and in mammalian hosts.

Background: More than 12,000 simple sequence repeats (SSRs) have been identified in the genome of Burkholderia mallei ATCC 23344. As a demonstrated mechanism of phase variation in other pathogenic bacteria, these may function as mutable loci leading to altered protein expression or structure variation. To determine if such alterations are occurring in vivo, the genomes of various single-colony passaged B.

Evaluation of surgical tissue from patients with Crohn's disease for the presence of Mycobacterium avium subspecies paratuberculosis DNA by in situ hybridization and nested polymerase chain reaction.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with tissue granuloma and histopathological alteration that resembles aspects in tuberculosis, leprosy, and paratuberculosis. Mycobacterium avium subsp paratuberculosis (MAP) is the causative agent of paratuberculosis, with a suspected role in the etiology of CD. We investigated the presence of MAP DNA in 31 surgical tissue samples from 20 subjects using fluorescence in situ hybridization (FISH) with the aid of confocal scanning laser microscopy and nested polymerase chain reaction (PCR) using the IS900 sequence unique to MAP.

Culture of Mycobacterium avium subspecies paratuberculosis from the blood of patients with Crohn's disease.

Background: Crohn's disease, a form of inflammatory bowel disease, resembles some aspects of tuberculosis, leprosy, and paratuberculosis. The role of Mycobacterium avium subspecies paratuberculosis (MAP) in Crohn's disease is controversial.

Methods: We tested for MAP by PCR and culture in buffy coat preparations from 28 individuals with Crohn's disease, nine with ulcerative colitis, and 15 without inflammatory bowel disease.
