So far, numerous genes have been found to associate with various strategies to resist and transform the toxic metalloid arsenic (here, we denote these genes as "arsenic-related genes"). However, our knowledge of the distribution, redundancies and organization of these genes in bacteria is still limited. In this study, we analyzed the 188 Burkholderiales genomes and found that 95% genomes harbor...

This study determined the role of plant and microbes in arsenite (AsIII) oxidation in the growth media and the location of AsIII oxidation and arsenate (AsV) reduction in Pteris vittata tissues. P. vittata grew in 0.10-0.27mM AsV or AsIII solution under aerated or sterile condition for 1h to 14d. Arsenic speciation was conducted in the growth media, biomass (roots, rhizomes, rachis, pinnae, and...

Paper introduces main characteristics and particulars of an innovative design for an Unmanned Surface Vehicle to autonomously launch and recover AUVs (Autonomous Underwater Vehicles) in open sea. The USV has an unconventional SWATH hull shape and in its smaller size version, it has dedicated hangar at midship that can host one medium size AUV, completely recovered onboard. The focus of this pap...

Proper disposal of As-hyperaccumulator Pteris vittata biomass (Chinese brake fern) enhances its application in phytoremediation. The goal of this study was to optimize As removal from P. vittata (PV) biomass by testing different particle sizes, extractants, extraction times and solid-to-liquid ratios. PV biomass was extracted using different extractants followed by different Mg-salts to recover...

The Canadian Continuous Positive Airway Pressure for Patients with Central Sleep Apnea and Heart Failure (CANPAP) trial was the first study to assess the effect of CPAP therapy in patients with chronic heart failure (CHF) and predominantly central sleep apnoea (CSA) on mortality [2]. Unfortunately, this study failed to demonstrate a prognostic benefit. However, there is ongoing debate as to how...

Arsenic (As)-resistant bacteria are abundant in the rhizosphere and tissues of As-hyperaccumulator Pteris vittata. However, little is known about their roles in As transformation and As uptake in P. vittata. In this study, the impacts of P. vittata tissue extracts with or without surface sterilization on As transformation in solutions containing 100 μg L-1 AsIII or AsV were investigated. After ...
