Wenjuan Shen, Hongliang Kang, Zhihui Ai
This study systematically compared the degradation of atrazine (ATR) with aerobic zero-valent aluminum (ZVAl/Air) and zero-valent iron (ZVI/Air) systems. By comparing the ATR degradation curves and rate in the ZVAl/Air and the ZVI/Air systems, a significant induction period was observed in the ZVAl/Air system, and the pseudo-first-order rate constant of ATR degradation in the second stage by ZVAl was 6.4 times faster than that by ZVI. The differences in ATR degradation patterns of the two systems stemmed from the different redox nature and electrical conductivity of aluminum (oxide) and iron (oxide)...

Amendment with biochar and/or compost has been proposed as a strategy to remediate soil contaminated with low levels of polycyclic aromatic hydrocarbons. The strong sorption potential of biochar can help sequestering contaminants while the compost may promote their degradation. An improved understanding of how sorption evolves upon soil amendment is an essential step towards the implementation of the approach. The present study reports on the sorption of pyrene to two soils, four biochars and one compost. Detailed isotherm analyzes across a wide range of concentration confirmed that soil amendments can significantly increase the sorption of pyrene...

OBJECTIVES: Cognitive remediation therapy (CRT) has shown significant improvement in cognition in schizophrenia. However, effect sizes of CRT have been reported to be modest raising the issue how to augment the effects of CRT on neurocognition and social cognition. Our aim was to examine whether the addition of computerized social cognition training would enhance the effects on neurocognition and social cognition as compared to CRT alone. METHODS: This is a 12-week, parallel group trial of 131 in- and out-patients with schizophrenia randomized to CRT (COGPACK or Brain Fitness) with computerized social cognition training (MRIGE), or CRT alone for 36 sessions...

On July 25, 1978, the first human was born following extracorporeal fertilization, an event that opened up a new medical science: expanding our knowledge of and developing novel treatments for infertility, radically changing the opportunities for families with inherited monogenic disorders, generating the new discipline of clinical embryology, and paving the way for studies into stem cell biology. In vitro fertilization (IVF), as it became known in its simplest form, went even further: it engaged the myriad of minds in human society...

Traditional medicine uses cultural knowledge and practices to promote health maintenance as well as diagnose and treat disease. In developing countries, the majority of people rely on traditional medicines; however, many of these practices have not been rigorously and systematically studied or reported. We review the current understanding and research behind traditional therapies prevalent in the Indian subcontinent, including mind-body and energy-based healing, botanical medicine, and herbal remedies. Topics covered include Ayurveda, yoga, naturopathy, Unani, Siddha, Sowa-Rigpa, homeopathy, and medicinal plants such as neem, guggul, tulsi, amla, and turmeric...

Warren J Winkelman
Complementary and alternative medicine approaches are popular among some patient segments due to the perception that they are "natural" and thus are believed to be less likely to be dangerous, to be less toxic, or to cause fewer side effects. In dermatology, these can include aromatherapy, botanicals, and essential oils (plant extracts). Preliminary evidence, biological activity studies, and small pilot clinical trials conducted outside of North America, mostly in young adults, suggest that some may have value in acne treatment...

INTRODUCTION:  The analysis of the periodic table of elements by Jan Scholten opened the way for a new kind of classification and repertorisation of homeopathic remedies. Thereby, group analysis (resorting to series and stages) makes precise prescriptions possible. This approach appears to yield striking results, even in severe cases. Whereas Hahnemann stressed the emotional state ('Gemüthssymptome', Organon § 210) when choosing a remedy, Scholten 200 years later investigated the mental picture that represents a life conflict or even a life theme that may maintain the disease process...

Cr6+ and Pb2+ are both highly toxic pollutants and commonly co-exist in some industrial effluents and contaminated waters. In this study, simultaneous removal of Cr6+ and Pb2+ by a novel sewage sludge-derived biochar immobilized nanoscale zero-valent iron (SSB-nZVI) was systematically investigated. It was well demonstrated that a porous structure was successfully formed on the SSB-nZVI when the starch was used as an additive. A synergistic effect on the adsorption and reduction over the SSB-nZVI was achieved, resulting in nearly 90 and 82% of Cr6+ and Pb2+ removal within 30 min, respectively...

Determining sources of heavy metals in soils, sediments and groundwater is important for understanding their fate and transport and mitigating human and environmental exposures. Artificially imported fill, natural sediments and groundwater from 240 ha of reclaimed land at Fishermans Bend in Australia, were analysed for heavy metals and other parameters to determine the relative contributions from different possible sources. Fishermans Bend is Australia's largest urban re-development project, however, complicated land-use history, geology, and multiple contamination sources pose challenges to successful re-development...

Pisolithus sp1 is an ectomycorrhizal (ECM) fungi that was chosen during a screening test of six strains of ECM fungi due to its ability to tolerate and remove hexavalent chromium (Cr(VI)). The physiological responses of Pisolithus sp1 to Cr(VI) exposure, the relationship between Pisolithus sp1 and exogenously added organic acids (EAOAs) or Na3 VO4 (H+ -ATPase inhibitor) and the ability of Pisolithus sp1 to reduce Cr(VI) in liquid culture were also investigated. Hydrogen ions (H+ ), which were produced directly by Pisolithus sp1, reduced the pH of the medium and played an important role in Cr(VI) reduction; however, Na3 VO4 significantly inhibited this process and resulted in a decrease in the Cr(VI) reduction rates...

Temporary base treatment is a potential remediation technique for heavy metals through adsorption, precipitation, and co-precipitation with minerals. Manipulation of pH with ammonia gas injection may be especially useful for vadose zone environments as it does not require addition of liquids that would increase the flux towards groundwater. In this research, we conducted laboratory batch experiments to evaluate the changes in uranium mobility and mineral dissolution with base treatments including sodium hydroxide, ammonium hydroxide, and ammonia gas...

Deterioration in dynamical activities may come up naturally or due to environmental influences in a massive portion of biological and physical systems. Such dynamical degradation may have outright effect on the substantive network performance. This requires us to provide some proper prescriptions to overcome undesired circumstances. In this paper, we present a scheme based on external feedback that can efficiently revive dynamism in damaged networks of active and inactive oscillators and thus enhance the network survivability...

Although soil contamination must be remediated by the polluters under current legal frameworks in numerous countries, the allocation of responsibilities for soil clean-up is still challenging in the case of multiple potentially responsible parties (PRPs). This study evaluated the individual contributions of two PRPs (Owners A & B) to heavy metal contamination in the soil environment near an abandoned smelter and compared the results with those from the conventional Gore Factor (GF) method. The soil in the study area was widely contaminated by various heavy metals...
