Sieve tube structural variation in Austrobaileya scandens and its significance for lianescence

Juan M. Losada, Zhe He, N. Michele Holbrook

Plant, Cell & Environment > 45 > 8 > 2460 - 2475

Lianas combine large leaf areas with slender stems, features that require an efficient vascular system. The only extant member of the Austrobaileyaceae is an endemic twining liana of the tropical Australian forests with well‐known xylem hydraulics, but the vascular phloem continuum aboveground remains understudied. Microscopy analysis across leaf vein orders and stems of Austrobaileya scandens revealed...

Colorectal Disease > 24 > 6 > 708 - 726

Aim The SARS‐CoV‐2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non‐delayed surgery. Methods This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January–April...

Changes in ploidy affect vascular allometry and hydraulic function in Mangifera indica trees

Miguel Barceló‐Anguiano, N. Michele Holbrook, José I. Hormaza, Juan M. Losada

The Plant Journal > 108 > 2 > 541 - 554

The enucleated vascular elements of the xylem and the phloem offer an excellent system to test the effect of ploidy on plant function because variation in vascular geometry has a direct influence on transport efficiency. However, evaluations of conduit sizes in polyploid plants have remained elusive, most remarkably in woody species. We used a combination of molecular, physiological and microscopy...

The AP‐Th 1000 – An advanced concept to use MOX of thorium in a closed fuel cycle

Giovanni L. Stefani, José R. Maiorino, João M. Losada Moreira

International Journal of Energy Research > 45 > 8 > 11642 - 11655

This work presents the feasibility studies to convert the UO₂ core of the Westinghouse AP1000 reactor to a U/Th core aiming at U/Th fuel recycling. The focus of the work is to establish a first core which allows normal operation of the AP1000 reactor and investigate a possible route for generating the ²³³U for U/Th fuel recycling. The converted core named AP‐Th1000 is divided in three homogenous zones...

Idioblasts and peltate hairs as distribution networks for water absorbed by xerophilous leaves

Juan M. Losada, Miriam Díaz, N. Michele Holbrook

Plant, Cell & Environment > 44 > 5 > 1346 - 1360

Capparis odoratissima is a tree species native to semi‐arid environments of South America where low soil water availability coexists with frequent night‐time fog. A previous study showed that water applied to leaf surfaces enhanced leaf hydration, photosynthesis and growth, but the mechanisms of foliar water uptake are unknown. Here, we combine detailed anatomical evaluations with water and dye uptake...

EuroSurg Collaborative, JC Glasbey, S Bibi, F Pata, more

Colorectal Disease > 22 > 12 > 2288 - 2297

Aim Aspiration is a common cause of pneumonia in patients with postoperative ileus. Insertion of a nasogastric tube (NGT) is often performed, but this can be distressing. The aim of this study was to determine whether the timing of NGT insertion after surgery (before versus after vomiting) was associated with reduced rates of pneumonia in patients undergoing elective colorectal surgery. Method...

Role of tumour location and surgical extent on prognosis in T2 gallbladder cancer: an international multicentre study

W. Kwon, H. Kim, Y. Han, Y. J. Hwang, more

British Journal of Surgery > 107 > 10 > 1334 - 1343

Background In gallbladder cancer, stage T2 is subdivided by tumour location into lesions on the peritoneal side (T2a) or hepatic side (T2b). For tumours on the peritoneal side (T2a), it has been suggested that liver resection may be omitted without compromising the prognosis. However, data to validate this argument are lacking. This study aimed to investigate the prognostic value of tumour location...

EuroSurg Collaborative, SJ Chapman, R Blanco‐Colino, S Pérez‐Ajates, more

British Journal of Surgery > 107 > 5 > 552 - 559

Background Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function. Methods A prospective, multicentre cohort study was undertaken across an international...

Search for heavy neutral leptons in decays of W bosons produced in 13 TeV pp collisions using prompt and displaced signatures with the ATLAS detector

The ATLAS collaboration, G. Aad, B. Abbott, D. C. Abbott, more

Journal of High Energy Physics > 2019 > 2019 > 10 > 1-47

Abstract The problems of neutrino masses, matter-antimatter asymmetry, and dark matter could be successfully addressed by postulating right-handed neutrinos with Majorana masses below the electroweak scale. In this work, leptonic decays of W bosons extracted from 32.9 fb⁻¹ to 36.1 fb⁻¹ of 13 TeV proton–proton collisions at the LHC are used to search for heavy neutral leptons (HNLs) that are produced...

The NEXT collaboration, J. Renner, G. Díaz López, P. Ferrario, more

Journal of High Energy Physics > 2019 > 2019 > 10 > 1-13

Abstract Excellent energy resolution is one of the primary advantages of electroluminescent high-pressure xenon TPCs. These detectors are promising tools in searching for rare physics events, such as neutrinoless double-beta decay (ββ0ν), which require precise energy measurements. Using the NEXT-White detector, developed by the NEXT (Neutrino Experiment with a Xenon TPC) collaboration, we show for...
