Hydrothermal carbonization of biomass wastes presents a promising step in the production of cost-effective activated carbon. In the present work, mesoporous activated carbon (HAC) was prepared by the hydrothermal carbonization of rattan furniture wastes followed by NaOH activation. The textural and morphological characteristics, along with adsorption performance of prepared HAC toward methylene blue (MB) dye, were evaluated. The effects of common adsorption variables on performance resulted in a removal efficiency of 96% for the MB sample at initial concentration of 25mg/L, solution pH of 7, 30°C, and 8h...

BACKGROUND: The burden of inflammatory bowel disease (IBD) in the older population is increasing. Older-onset disease is associated with reduced use of immunosuppressive medications. In addition, older patients may be more vulnerable to the effect of disease-related symptoms and consequently may experience worse health-related quality of life (HRQoL) compared with younger patients. METHODS: This prospective study included a cohort of patients with Crohn's disease and ulcerative colitis recruited from a single center...

Language comprehension engages a distributed network of frontotemporal, parietal, and sensorimotor regions, but it is still unclear how meaning of words and their semantic relationships are represented and processed within these regions and to which degrees lexico-semantic representations differ between regions and semantic types. We used fMRI and representational similarity analysis to relate word-elicited multivoxel patterns to semantic similarity between action and object words. In left inferior frontal (BA 44-45-47), left posterior middle temporal and left precentral cortex, the similarity of brain response patterns reflected semantic similarity among action-related verbs, as well as across lexical classes-between action verbs and tool-related nouns and, to a degree, between action verbs and food nouns, but not between action verbs and animal nouns...

Endosymbiosis of bacteria by eukaryotes is a defining feature of cellular evolution. In addition to well known bacterial origins for mitochondria and chloroplasts, multiple origins of bacterial endosymbiosis are known within the cells of diverse animals, plants, and fungi. Early-diverging lineages of terrestrial fungi harbor endosymbiotic bacteria belonging to the Burkholderiaceae. We sequenced the metagenome of the soil-inhabiting fungus Mortierella elongata and assembled the complete circular chromosome of its endosymbiont, Mycoavidus cysteinexigens, which we place within in a lineage of endofungal symbionts that are sister clade to Burkholderia...

New approaches to antimicrobial discovery are needed to address the growing threat of antibiotic resistance. The Streptomyces genus, a proven source of antibiotics, is recognized as having a large reservoir of untapped secondary metabolic genes, many of which are likely to produce uncharacterized compounds. However, most of these compounds are currently inaccessible, as they are not expressed under standard laboratory conditions. Here we present a novel methodology for activating these 'cryptic' metabolites by heterologously expressing a constitutively active pleiotropic regulator...

Stroke is a life-threatening disease that accounts for a considerable burden of mortality in both developing and developed world. Identification of specific biomarkers for stroke and its outcomes can greatly contribute to improved care of patients. MicroRNAs (miRNAs) are known as novel biomarkers that could be used as diagnostic, prognostic and therapeutic biomarkers. Various studies have shown that miRNAs have key roles in the pathogenesis of stroke, and its complications and outcomes. In addition, there is evidence showing that mesenchaymal stromal cell-derived exosomes containing miRNAs can be used for monitoring and treatment of various diseases such as stroke...
