Asia is the largest chemical producing continent globally. Accordingly, sustainable and green chemistry and engineering presents decided opportunities to stimulate innovation and realize a number of the United Nations Sustainable Development Goals. Engaging the priority research questions identified herein will require transdisciplinary coordination through existing and non-traditional partnerships within and among countries and sectors. Answering these questions will not be easy, but is necessary to achieve more sustainable environmental quality in Asia. This article is protected by copyright.

We determined that the USEPA's current RfDs could be met by consuming a single radish grown in soils with a PFOA concentration of 9.7 ng/g or a PFOS concentration of 90.5 ng/g. Using a combination of our own research and literature data on plant uptake of PFAAs from soil, we developed equations for predicting PFAA bioconcentration factors (BCFs) for plant shoot and root tissues grown in soils with a known percent organic carbon. This calculated BCF was then applied to six scenarios with measured soil PFAA concentrations to estimate PFAA concentrations in plants and potential exposure to humans and animals consuming harvested vegetation. Five of the six scenarios showed potential for surpassing USEPA PFAA RfDs at soil concentrations as low as 24 ng/g PFOA and 28 ng/g PFOS. This article is protected by copyright.

Eosinophilic esophagitis (EoE) is a chronic immune antigen-mediated disease found to be highly associated in patients with atopic disease and treated with dietary elimination with recommendations to utilize a dietician to prevent nutritional deficiencies. Nonetheless, the relationship between EoE and vitamin deficiency remains unclear. We aimed to systematically review the evidence to support a possible association between vitamin deficiency and eosinophilic esophagitis. Methods Electronic searches were performed with keywords relating to EoE and vitamins among pediatric patients in MEDLINE, EMBASE, and The Cochrane Library. Summary estimates were calculated. Citations were reviewed against pre-defined criteria. (Inclusion human subjects, aged 0-18, with eosinophilic esophagitis. Exclusion adults over 18 years, non-English papers). Results The search yielded 1707 studies. Five of these studies with a total of 137 pediatric patients were included in the systematic review. Outcome measures were assessed at different points in EoE treatment across studies. The single common outcome measure across all included studies was vitamin D. Reported prevalence of low vitamin D varied in these studies (0%-52%). Vitamin D levels of children with EoE both pre- and post-intervention were low. Conclusions There is limited published literature on vitamin deficiencies associated with EoE both pre- and post-intervention. The limited data on vitamin D suggest that insufficiency or deficiency may be present in these patients, but it remains unclear whether deficiency is caused by diet. More prospective, well-defined studies, in addition to routine reporting on dietary intake and nutritional status, are needed to make any conclusions or recommendations for screening.Antibiotic resistance in acne was first observed in the 1970s and has been a major concern in dermatology since the 1980s. The resistance rates and types of antimicrobials have subsequently shown great variations in regions and countries. Illustrative of this is the resistance to topical erythromycin and clindamycin which continues to be a problem worldwide, while resistance to systemic treatment with tetracyclines has remained low during the past decade. The resistance for the newer macrolides like azithromycin and clarithromycin has been increasing. The results of antibiotic resistance may include treatment failure of acne, disturbance of skin microbiota, induction of opportunistic pathogens locally and systemically, and dissemination of resistant strains to both healthcare personnel and the general population. Capsazepine in vitro The ensuing complications, such as aggravated opportunistic infections caused by Propionibacterium acnes and the emergence of multiresistant superbugs, have not yet been confirmed.Background Acral chilblain-like lesions are being increasingly reported during COVID-19 pandemic. However, only few patients proved positivity for SARS-CoV-2 infection. The relationship between this skin manifestation and COVID-19 infection has not been clarified yet. Objective To thoroughly characterize a prospective group of patients with chilblain-like lesions, and to investigate the possible relationship with SARS-CoV-2 infection. Methods Following informed consent, patients underwent (i) clinical evaluation, (ii) RT-PCR and serology testing for SARS-CoV-2, (iii) digital videocapillaroscopy of finger- and toe-nailfolds, (iv) blood testing to screen for autoimmune diseases and coagulation anomalies, and (v) skin biopsy for histopathology, direct immunofluorescence, and, in selected cases, electron microscopy. Results Nineteen patients, all adolescents (mean age 14 years), were recruited. 11/19 (58%) of them and/or their cohabitants reported flu-like symptoms one to two months prior to skin manifestation on history data and the detection of anti-SARS-COV-2 IgA strongly suggest a relationship between skin lesions and COVID-19. Further investigations on the mechanisms of SARS-CoV-2 infection in children and pathogenesis of chilblain-like lesions are warranted.Depletion of fossil fuels and environmental concern has compelled us to search for alternative fuel. Hydrogen is considered as a dream fuel as it has high energy content (142 kJ g-1 ) and is not chemically bound to carbon. At present, fossil fuel-based methods for producing hydrogen require high-energy input, which makes the processes expensive. The major processes for biohydrogen production are biophotolysis, microbial electrolysis, dark fermentation, and photofermentation. Fermentative hydrogen production has the additional advantages of potentially using various waste streams from different industries as feedstock. Novel strategies to enhance the productivity of fermentative hydrogen production include optimization in pretreatment methods, integrated fermentation systems (sequential and combined fermentation), use of nanoparticles as additives, metabolic engineering of microorganisms, improving the light utilization efficiency, developing more efficient photobioreactors, etc. More focus has been given to produce biohydrogen in a biorefinery approach in which, along with hydrogen gas, other metabolites (ethanol, butyric acid, 1,3-propanediol, etc.
