Most terrestrial carnivorous plants are specialized on insect prey digestion to obtain additional nutrients. Few species of the genus Nepenthes developed mutualistic relationships with mammals for nitrogen supplementation. Whether dietary changes require certain enzymatic composition to utilize new sources of nutrients has rarely been tested. Here, we investigated the role of urease for Nepenthes hemsleyana that gains nitrogen from the bat Kerivoula hardwickii while it roosts inside the pitchers. We hypothesized that N...

BACKGROUND: Gender differences may exist for patients undergoing shoulder arthroplasty. Limited data suggest that women may have worse preoperative disability and outcomes. Our objective was to determine whether gender influences preoperative disability and patient-reported outcomes after reverse total shoulder arthroplasty. METHODS: Data were prospectively collected for patients who underwent reverse total shoulder arthroplasty for rotator cuff arthropathy or osteoarthritis with a rotator cuff tear at a single institution between 2009 and 2015...

Carnivorous plants of the genus Nepenthes supplement their nutrient deficiency by capturing arthropods or by mutualistic interactions, through their leaf-evolved biological traps (pitchers). Though there are numerous studies on these traps, mostly on their prey capture mechanisms, the gas composition inside them remains unknown. Here we show that, Nepenthes unopened pitchers are CO2-enriched 'cavities', when open they emit CO2, and the CO2 gradient around open pitchers acts as a cue attracting preys towards them...

Plants can generate a spectacular array of complex shapes, many of which exhibit elaborate curvature in three dimensions, illustrated for example by orchid flowers and pitcher-plant traps. All of these structures arise through differential growth. Recent findings provide fresh mechanistic insights into how regional cell behaviours may lead to tissue deformations, including anisotropies and curvatures, which shape growing volumes and sheets of cells. Here were review our current understanding of how genes, growth, mechanics, and evolution interact to generate diverse structures...

The care of patients on extracorporeal corporeal oxygenation support takes a coordinated effort among the team of nurses, midlevel providers, perfusionists, respiratory therapists, pharmacists, and physicians. Attention on the details of the circuitry and its interactions with the patient, the resolution of the disease process and the ongoing plan of care, and unique issues in the intensive care unit are crucial for success.

Extracorporeal membrane oxygenation (ECMO) is a life-saving technique when patients require pulmonary and/or cardiac support for days to weeks for recovery, bridge to decision, or transplantation. Due to complications associated with ECMO, it is best to stay on ECMO as little time as necessary. Foremost is weaning from ECMO, but the post-ECMO period recapitulates the entire field of critical care. Identified issues include (1) potential for systemic inflammatory response syndrome post-decannulation; (2) post-ECMO complications, such as deep vein thrombosis, wounds, renal failure, and stroke; (3) delirium; (4) posttraumatic stress disorder; (5) rehabilitation; and (6) end of life...

Loss of shoulder motion, especially to flexion and external rotation, may increase the risk of nontraumatic shoulder and elbow injuries in elite pitchers. However, the etiology of these injuries is likely mulitifactorial, and before we direct our therapists to abandon sleeper stretches in favor of flexion and external rotation exercises, further research is needed to keep pitchers off the disabled list and on the mound.

INTRODUCTION: TP53 mutations are common in non-small cell lung cancer (NSCLC) and have been reported as prognostic of poor outcome. The impact of TP53 co-mutations in epidermal growth factor receptor (EGFR)-mutated NSCLC is unclear. MATERIALS AND METHODS: Tissue from 105 patients with EGFR-mutated NSCLC at Princess Margaret Cancer Centre was analyzed by next-generation or Sanger sequencing to determine TP53 mutational status. Associations between TP53 status and baseline patient and tumor characteristics, treatments and outcomes (relapse-free survival [RFS] after surgical resection, overall survival [OS], overall response rate [ORR] and progression-free survival [PFS] on EGFR tyrosine kinase inhibitors [TKIs]), were investigated...

Anthropogenic climate change is predicted to have profound effects on species distributions over the coming decades. In this paper, we used maximum entropy modelling (Maxent) to estimate the effects of projected changes in climate on extent of climatically-suitable habitat for two Nepenthes pitcher plant species in Borneo. The model results predicted an increase in area of climatically-suitable habitat for the lowland species Nepenthes rafflesiana by 2100; in contrast, the highland species Nepenthes tentaculata was predicted to undergo significant loss of climatically-suitable habitat over the same period...

Carnivorous plants exploit animals as a nutritional source and have inspired long-standing questions about the origin and evolution of carnivory-related traits. To investigate the molecular bases of carnivory, we sequenced the genome of the heterophyllous pitcher plant Cephalotus follicularis, in which we succeeded in regulating the developmental switch between carnivorous and non-carnivorous leaves. Transcriptome comparison of the two leaf types and gene repertoire analysis identified genetic changes associated with prey attraction, capture, digestion and nutrient absorption...

Prototype 10 × 10 and 20 × 20-cm(2) electron collimators were designed for the Elekta Infinity accelerator (MLCi2 treatment head), with the goal of reducing the trimmer weight of excessively heavy current applicators while maintaining acceptable beam flatness (±3% major axes, ±4% diagonals) and IEC leakage dose. Prototype applicators were designed initially using tungsten trimmers of constant thickness (1% electron transmission) and cross-sections with inner and outer edges positioned at 95% and 2% off-axis ratios (OARs), respectively, cast by the upstream collimating component...

The slippery peristome of the pitcher plant Nepenthes has attracted much attention due to its unique function for preying on insects. Recent findings on the peristome surface of Nepenthes alata demonstrate a fast and continuous unidirectional liquid transport, which is enabled by the combination of a pinning effect at the sharp edges and a capillary rise in the wedge, deriving from the multiscale structure, which provides inspiration for designing and fabricating functional surfaces for unidirectional liquid transport...
