Abstract

"Save Soil Save Earth" is not just a catchphrase; it is a necessity to protect soil ecosystem from the unwanted and unregulated level of xenobiotic contamination. Numerous challenges such as type, lifespan, nature of pollutants and high cost of treatment has been associated with the treatment or remediation of contaminated soil, whether it be either on-site or off-site. Due to the food chain, the health of non-target soil species as well as human health were impacted by soil contaminants, both organic and inorganic. In this review, the use of microbial omics approaches and artificial intelligence or machine learning has been comprehensively explored with recent advancements in order to identify the sources, characterize, quantify, and mitigate soil pollutants from the environment for increased sustainability. This will generate novel insights into methods for soil remediation that will reduce the time and expense of soil treatment.

Abstract

The global rise in industrialization and vehicularization has led to the increasing trend in the use of different crude oil types. Among these mobil oil has major application in automobiles and different machines. The combustion of mobil oil renders a non-usable form that ultimately enters the environment thereby causing problems to environmental health. The aliphatic and aromatic hydrocarbon fraction of mobil oil has serious human and environmental health hazards. These components upon interaction with soil affect its fertility and microbial diversity. The recent advancement in the omics approach viz. metagenomics, metatranscriptomics and metaproteomics has led to increased efficiency for the use of microbial based remediation strategy. Additionally, the use of biosurfactants further aids in increasing the bioavailability and thus biodegradation of crude oil constituents. The combination of more than one approach could serve as an effective tool for efficient reduction of oil contamination from diverse ecosystems. To the best of our knowledge only a few publications on mobil oil have been published in the last decade. This systematic review could be extremely useful in designing a micro-bioremediation strategy for aquatic and terrestrial ecosystems contaminated with mobil oil or petroleum hydrocarbons that is both efficient and feasible. The state-of-art information and future research directions have been discussed to address the issue efficiently.

Abstract

Wastewater is one of the most common by-products of almost every industrial process. Treatment of wastewater alone, before disposal, necessitates an excess of energy. Environmental concerns over the use of fossil fuels as a source of energy have prompted a surge in demand for alternative energy sources and the development of sophisticated procedures to extract energy from unconventional sources. Treatment of municipal and industrial wastewater alone accounts for about 3% of global electricity use while the amount of energy embedded in the waste is at least 2-4 times greater than the energy required to treat the same effluent. The microbial electrolysis cell (MEC) is one of the most efficient technologies for waste-to-product conversion that uses electrochemically active bacteria to convert organic matter into hydrogen or a variety of by-products without polluting the environment. This paper highlights existing obstacles and future potential in the integration of Microbial Electrolysis Cell with other processes like anaerobic digestion coupled system, anaerobic membrane bioreactor and thermoelectric micro converter.

Abstract

Background: Initial dose adjustment is recommended for patients with known UGT1A1∗28 homozygosity for both conventional irinotecan and liposomal irinotecan (nal-IRI). A recent population pharmacokinetic (PK) study showed that Asian patients had a lower prevalence of UGT1A1∗28 homozygosity but a significantly higher maximum blood concentration of SN-38 (SN-38 Cmax) and a higher incidence of grade ≥3 neutropenia after nal-IRI administration than Caucasian patients. The current study investigated the association of UGT1A1 polymorphisms, including the Asian prevalent UGT1A1∗6, PK and toxicities of nal-IRI-based therapy in the Asian population., Patients and Methods: A total of 162 patients with nal-IRI-based therapy and available UGT1A1∗6 and UGT1A1∗28 genotyping were included, with 82 Asian patients from six previous phase I or II studies of nal-IRI (cohort 1) and another 80 patients with nal-IRI + 5-fluorouracil/leucovorin every 2 weeks as real-world practice in a single institute in Taiwan (cohort 2)., Results: The frequency of UGT1A1∗6 or UGT1A1∗28 homozygosity/compound heterozygosity was 9.3%, with UGT1A1∗6/∗6 in 2.5%, UGT1A1∗28/∗28 in 1.9% and UGT1A1∗6/∗28 in 4.9%. Among the 53 patients in cohort 1 with available PK data, all 7 patients with homozygosity/compound heterozygosity harbored UGT1A1∗6 and had a significantly higher level of median dose-normalized area under the concentration-time curve (AUC) and Cmax of SN-38 than those with single heterozygosity/wild type. Of the entire study population, the incidence of grade ≥3 neutropenia and diarrhea was significantly higher in patients with homozygosity/compound heterozygosity than in those with single heterozygosity/wild type, 73.3% versus 38.1% (P = 0.012, Fisher's exact test) and 33.3% versus 9.5% (P = 0.018, Fisher's exact test), respectively., Conclusion: The results suggest that the recommendation of a lower starting dose of nal-IRI for patients with UGT1A1∗28 homozygosity should be extended to include patients with UGT1A1∗6 homozygosity/compound heterozygosity., Competing Interests: Disclosure YWW was employed by PharmaEngine, Inc.
