Screening for tolerant and high biomass producing plants is important for phytoextraction efforts in remediating agricultural soils contaminated by heavy metals. We carried out a greenhouse experiment involving a soil cadmium (Cd) concentration gradient (0.1, 0.5, 1, 2, 4, and 8 mg kg-1 ) to assess growth and phytoextraction capacity of king grass (Pennisetum sinese Roxb.) in soils contaminated by Cd and to explore changes in diversity and structure of rhizosphere soil bacterial communities in response to long-term Cd pollution...

The ecological multifunctionality of colour often results in multiple selective pressures operating on a single trait. Most research on colour evolution focuses on males because they are the most conspicuous sex in most species. This bias can limit inferences about the ecological drivers of colour evolution. For example, little is known about population divergence in colour of female threespine stickleback ( Gasterosteus aculeatus ), which is among the most intensively-studied model vertebrates in evolution, ecology, and behaviour...

Modified TiO2 catalysts are of interest in environmental water remediation since they can lead to efficient electron-hole separation and greatly enhance the photocatalytic properties of TiO2 . Reactive oxygen species (ROS), such as the superoxide radical (O2 - ), hydroxyl radical (OH), and positive valence band holes (h+ VB ), have been reported as the main oxidative species involved in photocatalytic degradation processes. In this work, the role of these species using TiO2 , TiO2 /Pt 0.5 wt%, and TiO2 /Ag 10 wt% has been examined in order to clarify the oxidation pathways...

Secondary lead smelting is a widespread industrial activity which has exacerbated Pb or Cd contamination of soil and water across the world. Soil physicochemical properties, soil enzyme activities, heavy metal concentrations, and bacterial diversity near a secondary lead plant in Xuzhou, China were examined in this study. The results showed that secondary lead smelting activities influenced nearby soils. Soil acidification decreased one order of magnitude, with a mean value of 7.3. Soil organic matter also showed a downward trend, while potassium and nitrogen appeared to accumulate...

INTRODUCTION: Professionalism rests upon a number of individual, environmental, and societal level factors, leading to specific professional behavior in specific situations. Focusing on professional lapses to identify and remediate unprofessional physicians is incomplete. We explored professionalism in practicing internal medicine physicians in the context of everyday practice, to highlight how typical experiences contribute to positive, yet often unnoticed, professional behavior. METHODS: In-depth interviews were used to uncover 13 physicians' most meaningful experiences of professionalism...

Dear Editor, Gestational pemphigoid (GP) is a rare autoimmune bullous dermatosis in pregnancy. GP usually occurs during the second or third month of pregnancy. It clinically manifests as the development of either early-onset urticarial lesions or late-onset subepidermal blisters that may linger for weeks or even months. Herein we report the case of a 45-year-old woman with the distinctive clinical onset of GP. A forty-five-year-old woman, gravida I, para 0, at 27 weeks gestation, was referred for evaluation to our Department with an extensive pruritic eruption that had developed over the previous 7 days...

Scabies and pediculosis are common parasitic infestations of the skin and hair, manifesting with intense pruritus and effectively treated with modern medications. Because of the attached social stigma linking it with poverty and poor hygiene, patients will often attempt alternative folk-based remedies before confiding in their physicians. We conducted a comprehensive bibliographical study of historic folk literature and interviewed 70 individuals experienced in everyday application of folk medicine in order to categorize available remedies and provide a modern, scientific comment on their effectiveness and dangers...

Curcumin is a polyphenolic compound with a long history of use as an herbal remedy, dietary spice and food-coloring agent. Despite curcumin possesses a wide range of biological and pharmacological activities, it exhibits extremely poor bioavailability, which makes its pharmacology intriguing and also hinders its clinical application. In recent years, there is ample evidence supporting the associations between the alteration of gut microbiota and many diseases. Interestingly, after oral administration, curcumin shows its preferential distribution and accumulation in the intestine...

BACKGROUND: Posterior nasal fricatives are a learned compensatory articulation error and commonly substituted for oral fricatives. Treatment of such articulation errors requires the modification or teaching of skilled movements. A motor-based approach is designed to teach the complex motor skill movement sequences required in the production of sounds. Although motor learning research is well established, little has been done to determine how the approach changes the underlying physiology of articulatory movements...

Since the 1970s multiculturalist policies that recognize and accommodate ethnocultural diversity have been implemented across western democracies. However, the tide seems to have changed: a 'backlash against multiculturalism' has been occurring since the 1990s. While it remains unclear whether this backlash is a matter of rhetoric or if there is indeed a wholesale retreat from multiculturalism, several scholars, politicians and journalists have invoked a pervasive narrative of the rise/advance and fall/retreat of multiculturalism...

Although plants of the genus Pennisetum can accelerate the removal of atrazine from its rhizosphere, the roles played by this plant in adjusting the soil environment and soil microorganism properties that might contribute to pollutant removal are incompletely understood. We selected Pennisetum americanum (L.) K. Schum ( P. americanum ) as the test plant and investigated the interaction between P. americanum and atrazine-contaminated soil, focusing on the adjustment of the soil biochemical properties as well as bacterial functional and community diversity in the rhizosphere using Biolog EcoPlates and high-throughput sequencing of the 16S rRNA gene...

The bovine rumen hosts a diverse microbiota, which is highly specialized in the degradation of lignocellulose. Ruminal bacteria, in particular, are well equipped to deconstruct plant cell wall polysaccharides. Nevertheless, their potential role in the breakdown of the lignin network has never been investigated. In this study, we used functional metagenomics to identify bacterial redox enzymes acting on polyaromatic compounds. A new methodology was developed to explore the potential of uncultured microbes to degrade lignin derivatives, namely kraft lignin and lignosulfonate...

Education is a frequently recommended remedy for driver sleepiness in occupational settings, although not many studies have examined its usefulness. To date, there are no previous on-road randomized controlled trials investigating the benefits of training on sleepiness among employees working in road transport. To examine the effects of an educational intervention on long-haul truck drivers' sleepiness at the wheel, amount of sleep between work shifts, and use of efficient sleepiness countermeasures (SCM) in association with night and non-night shift, a total of 53 truck drivers operating from southern Finland were allocated into an intervention and a control group using a stratified randomization method (allocation ratio for intervention and control groups 32:21, respectively)...
