Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

OBJECTIVE: Are there key attributes of leaders? Extrovert versus introvert? Charismatic? Detail oriented? Visionary? How do past leaders of the Medical Library Association (MLA) stack up? What leadership skills will MLA's leaders need in a complex information future? Leadership attributes of MLA's past and current presidents were studied to determine the common characteristics shared among these leaders. An examination of the leadership literature identified critical leadership characteristics essential to successful future leaders...

BACKGROUND: The literature suggests that person-centred care can contribute to quality of life and wellbeing of nursing home residents, relatives and staff. However, there is sparse research evidence on how person-centred care can be operationalised and implemented in practice, and the extent to which it may promote wellbeing and satisfaction. Therefore, the U-Age nursing home study was initiated to deepen the understanding of how to integrate person-centred care into daily practice and to explore the effects and meanings of this...

Pseudomonas brassicacearum strain L13-6-12 is a rhizosphere colonizer of potato, lettuce and sugar beet. Previous studies have shown that this motile, Gram-negative, non-sporulating bacterium is an effective biocontrol agent against different phytopathogens. Here, we announce and describe the complete genome sequence of P. brassicacearum L13-6-12 consisting of a single 6.7 Mb circular chromosome that consists of 5773 protein coding genes and 85 RNA-only encoding genes. Genome analysis revealed genes encoding specialized functions for pathogen suppression, thriving in the rhizosphere and interacting with eukaryotic organisms...

The Eurylaimides is one of the few passerine groups with a pantropical distribution. In this study, we generated a multi-calibrated tree with 83% of eurylaimid species diversity based on 30 molecular loci. Particular attention was given to the monotypic Sapayoidae to reconstruct the biogeography of this radiation. We conducted several topological tests including nonoverlapping subsampling of the concatenated alignment and coalescent species tree reconstruction. These tests firmly placed the South American Sapayoidae as the sister group to all other Eurylaimides families (split at ∼28 Ma), with increasing branch support as highly variable sites were removed...

Reports from health workers, school staff and community members in rural NSW suggested that bacterial skin infections are a significant health issue for Aboriginal children and their families, affecting quality of life and contributing to poor school attendance. Current NSW treatment guidelines do not incorporate important sociocultural factors or ways of living in Aboriginal communities. The aim of this qualitative study was to gain a deeper understanding of the experience of parents and carers of Aboriginal children affected by skin infections and of other community members, health workers and school staff, and what actions have been considered successful or unsuccessful in reducing the recurrence of infection...

BACKGROUND AND AIMS: In a cost-benefit framework, plant carnivory is hypothesized to be an adaptation to nutrient-poor soils in sunny, wetland habitats. However, apparent exceptions to this cost-benefit model exist, although they have been rarely studied. One of these exceptions is the carnivorous subshrub Drosophyllum lusitanicum, which thrives in Mediterranean heathlands on dry sandstone soils and has relatively well-developed, xeromorphic roots. Here, the roles of leaf (carnivory) and root (soil) nutrient uptake in growth promotion of this particular species were assessed...

The primary aspiration in the microbial observatory is to advance the understanding of freshwater bacterioplankton, whose diversity and population dynamics are currently the least understood off all freshwater planktonic organisms. Through identification and characterization of bacterial populations in a suite of fresh water bodies, we are able to gain significant new insight into the ecological niches of bacteria in diverse freshwater ecosystems. Given the facts that lakes and other inland freshwaters play a more critical role in the global carbon budget and that lakes have been described as early indicators of both regional and global environmental change, the role of microbes in these processes is of renewed interest...

Leishmania parasites have evolved to endure the acidic phagolysosomal environment within host macrophages. How Leishmania cells maintain near-neutral intracellular pH and proliferate in such proton-rich milieu remains poorly understood. We report here that for thriving in acidic condition Leishmania major relies on a cytosolic and a cell surface carbonic anhydrase viz. LmCA1 and LmCA2. Upon exposure to acidic medium, intracellular pH of the LmCA1(+/-), LmCA2(+/-) and LmCA1(+/-): LmCA2(+/-) mutant strains dropped by varying extents that led to cell cycle delay, growth retardation and morphological abnormalities...

It is increasingly common for nephrologists to be faced with the question of whether starting dialysis on an elderly patient is appropriate. We present an extraordinary case of a 103-year-old person who has become the oldest patient in our unit, reportedly the world, to not only remain on haemodialysis, but to thrive on it. This case adds to the compelling literature, which suggests that it is indeed the number and severity of comorbidities that is more likely to impact survival than age alone.

Vitamin B12 deficiency may be responsible of serious hematologic and neurodevelopmental abnormalities. We report the case of an infant who was hospitalized because of recurrent infections, failure to thrive, hypotonia, and weakness. He was 8 months old and had been exclusively breastfed. Blood cell count showed pancytopenia with megaloblastic bone marrow. The serum IgG concentration was low. Vitamin B12 level was very low and associated with increased urinary methylmalonic acid. Cobalamin deficiency was caused by mother's unrecognized pernicious anemia...

The middle Eocene Messel and Eckfeld localities are renowned for their excellently preserved faunas and diverse floras. Here we describe for the first time pollen from insect-pollinated plants found in situ on well-preserved ancient bees using light and scanning electron microscopy. There have been 140 pollen types reported from Messel and 162 pollen types from Eckfeld. Here we document 23 pollen types, six from Messel and 18 from Eckfeld (one is shared). The taxa reported here are all pollinated by insects and mostly not recovered in the previously studied dispersed fossil pollen records...

BACKGROUND: Lysinuric protein intolerance (LPI) is a rare metabolic disease resulting from recessive-inherited mutations in the SLC7A7 gene encoding the cationic amino-acids transporter subunit y(+)LAT1. The disease is characterised by protein-rich food intolerance with secondary urea cycle disorder, but symptoms are heterogeneous ranging from infiltrative lung disease, kidney failure to auto-immune complications. This retrospective study of all cases treated at Necker Hospital (Paris, France) since 1977 describes LPI in both children and adults in order to improve therapeutic management...

INTRODUCTION: Conditions requiring an esophagectomy and esophageal replacement are rare in children. The preferred method and ideal replacement organ continue to be debated. We present long-term outcomes in children treated with esophagectomy and gastric pull-up. METHODS: We conducted a retrospective review of all the patients who underwent a esophagectomy and gastric pull-up at two major pediatric institutions from 2004 to 2015. Follow-up data were obtained for children when available, including any postoperative complications, need for dilation of strictures, and current feeding method...

Neglected tropical diseases (NTDs) are a diverse group of acute and chronic conditions with distinct characteristics that thrive mainly among the poorest populations, almost exclusively in tropical countries. To evaluate the relevance and impact of NTDs in a temperate area, the number and features of patients diagnosed with NTDs at the Infectious and Tropical Diseases Unit (ITDU), Azienda Ospedaliero-Universitaria Careggi, Florence, Italy between 2000 and 2015 were retrospectively reviewed. Overall 289 NTD cases were diagnosed in 283 subjects accounting for 2...

Colonial-nesting organisms can strongly alter the chemical and biotic conditions around their aggregation sites, with cascading impacts on other components of the ecosystem. In tropical Australia, Metallic Starlings (Aplonis metallica) nest in large colonies far above the forest canopy, in emergent trees. The ground beneath those trees is open, in stark contrast to the dense foliage all around. We surveyed the areas beneath 27 colony trees (and nearby randomly chosen trees lacking bird colonies) to quantify the birds' impacts on soil and vegetation characteristics, and to test alternative hypotheses about the proximate mechanisms responsible for the lack of live vegetation beneath colony trees...
