Bronchial sutures grafts by epiplooplasty is a method used to allow a better vascularisation of the bronchial sutures. The authors purpose an other method using the pericardial fatty fringes (P.F.F.). The vascularisation of P.F.F. was studied on 30 fresh cadavers and 8 patients before surgery. Angiography of the internal thoracic artery was done in the first group and M.R.I. in the second group. M.R.I. is better than angiography because numerous parietal vessels project in the angiogram, and they overlap pericardial fat fringes vessels.

CsPbBr NCs Confined and In Situ Grown in ZIF-8: A Stable, Sensitive, Reliable Fluorescent Sensor for Evaluating the Acid Value of Edible Oils.

Rapidly and sensitively evaluating the acid value (AV) of edible oils is significant to ensuring food quality and safety. Cesium lead bromide perovskite nanocrystals (CsPbBr NCs) are an effective candidate for AV detection; however, their instability restricts wide applications. Herein, CsPbBr@ZIF-8 was prepared by confining and growing CsPbBr NCs in situ into zeolitic imidazolate framework-8 (ZIF-8) to improve the stability, and a fluorescence sensor was established to evaluate the AV of edible oils.

Coastal blue carbon ecosystems (BCE) support nearshore food webs and provide habitat for many commercially important fish and crustacean species. However, the complex links between catchment vegetation and the carbon food-base of estuarine systems are difficult to disern. We employed a multi-biomarker approach (stable isotope ratios - δC and δN, fatty acid trophic markers - FATMs and metabolomics - central carbon metabolism metabolites) to test links between estuarine vegetation and the food sources available to commercially important crabs and fish occurring within the river systems of the near-pristine eastern coastline of the Gulf of Carpentaria, Australia.

Six strains, KI11_D11, KI4_B1, KI11_C11, KI16_H9, KI4_A6 and KI3_B9, were isolated from insects and flowers on Kangaroo Island, South Australia. On the basis of 16S rRNA gene phylogeny, strains KI11_D11, KI4_B1, KI11_C11, KI16_H9, KI4_A6 were found to be closely related to Ru20-1. Due to the lack of a whole genome sequence for this species, whole genome sequencing of Ru20-1 was undertaken.

Understanding the change in coal structure during heat treatment is the basis of efficient and clean utilization of coal. In this study, high-resolution transmission electron microscopy (HRTEM) was used to analyse the changes in the aggregate structure and ultramicropores of Zhungdong coal samples (Xinjiang, China) that were heated from ambient temperature to 800 °C respectively. Then, the relationship between their HRTEM characteristics and the corresponding reaction activation energy were also analyzed.

Background: Diaphragm pacing allows certain ventilator-dependent patients to achieve weaning from mechanical ventilation. The reference method consists in implanting intrathoracic contact electrodes around the phrenic nerve during video-assisted thoracic surgery, which involves time-consuming phrenic nerve dissection with a risk of nerve damage. Identifying a phrenic segment suitable for dissection-free implantation of electrodes would constitute progress.
