TL;DR: A retrospective study of 251 renal biopsies identified to have a primary interstitial disease from regions endemic for CKDU finds the mean age of patients with stage I disease was significantly lower than those of the other stages, and about 79.2%, 55%, 49.1% and 50% in stage I, II, III and IV disease respectively were asymptomatic at the time of biopsy.
Abstract: Chronic kidney disease of unknown etiology (CKDU) is endemic among the rural farming communities in several localities in and around the North Central region of Sri Lanka. This is an interstitial type renal disease and typically has an insidious onset and slow progression. This study was conducted to identify the pathological features in the different clinical stages of CKDU. This is a retrospective study of 251 renal biopsies identified to have a primary interstitial disease from regions endemic for CKDU. Pathological features were assessed and graded in relation to the clinical stage. The mean age of those affected by endemic CKDU was 37.3 ± 12.5 years and the male to female ratio was 3.3:1. The predominant feature of stage I disease was mild and moderate interstitial fibrosis; most did not have interstitial inflammation. The typical stage II disease had moderate interstitial fibrosis with or without mild interstitial inflammation. Stage III disease had moderate and severe interstitial fibrosis, moderate interstitial inflammation, tubular atrophy and some glomerulosclerosis. Stage IV disease typically had severe interstitial fibrosis and inflammation, tubular atrophy and glomerulosclerosis. The mean age of patients with stage I disease (27 ± 10.8 years) was significantly lower than those of the other stages. About 79.2%, 55%, 49.1% and 50% in stage I, II, III and IV disease respectively were asymptomatic at the time of biopsy.

TL;DR: In this paper, the authors compared the spatial representation of soil organic carbon (SOC) stocks and active-layer thicknesses predicted by the coupled Model Intercomparison Project Phase 5 (CMIP5) ESMs with those predicted from geospatial predictions.

TL;DR: Southeast Asian Schistosoma spindale and S. incognitum populations were shown to fall into their respective con-specific cohesive groupings and a revised phylogeographical model is proposed in the light of these findings.
Abstract: Partial (DNA) sequences were collected for 2 mitochondrial loci (Srrna and Lrrna, the rrnS and rrnL rRNA genes respectively) for Schistosoma indicum group species from 4 Southeast Asian countries. The samples included 7 populations, 4 of which were previously unstudied. In 11 cases the combination of locus and population was new. The aim of the study was to provide a phylogeny based on new independent data and multiple populations (earlier studies had mostly used a common set of field samples or laboratory lines) and to examine interrelationships and phylogeography within this species group. Paraphyly of the S. indicum group was confirmed, as was the basal position of Schistosoma incognitum in the Schistosoma phylogeny. Southeast Asian Schistosoma spindale and S. incognitum populations were shown to fall into their respective con-specific cohesive groupings. Estimated divergence times for these taxa were shown to be related to Pleistocene changes in sea level and the radiation of definitive host groups. A revised phylogeographical model is proposed in the light of these findings.

TL;DR: In this article, a series of nanocrystalline cellulose (NCC)-mesoporous silica composites with attached double-amidoxime groups was synthesized and examined for CO2 sorption at both ambient (25 °C) and elevated temperatures (120 °C).
Abstract: A series of nanocrystalline cellulose (NCC)–mesoporous silica composites (NCC-AO) with attached double-amidoxime groups is synthesized and examined for CO2 sorption at both ambient (25 °C) and elevated temperatures (120 °C). NCC-AO composites showed high CO2 uptakes at ambient pressure, namely, 3.30 mmol g−1 at 25 °C and 5.54 mmol g−1 at 120 °C. The CO2 sorption capacity of NCC-AO at 1 atm and 120 °C is very high and exceeds the values reported so far for other sorbents under the same conditions. NCC-AO sorbents exhibited very good recyclability and were stable after ten successive adsorption/desorption cycles with negligible losses of the sorption capacity. Due to the high sorption capacity, reusability, thermal stability, relatively low cost and simple synthesis route, the NCC-AO composites show good potential as effective sorbents and catalysts, including CO2 sorption at elevated temperatures.

TL;DR: Data indicate that the chitin-derived activated carbon can be used for adsorption-based environmental and related applications.
Abstract: Activated carbon was prepared by carbonization and KOH activation of chitin aerogels. The resulting carbon featured high CO2 adsorption of 5.02 mmol/g at 0 °C and 3.44 mmol/g at 25 °C under ambient pressure of 1 atm. The activated carbon showed a high specific surface area of ~ 520 m2/g, total pore volume of 0.30 cm3/g, and volume of micropores of ~ 0.19 cm3/g. KOH activation of carbonized chitin aerogels resulted in about 37-fold increase in the specific surface area and about 95-fold increase in the volume of micropores as compared to the as-synthesized chitin aerogel. These data indicate that the chitin-derived activated carbon can be used for adsorption-based environmental and related applications.
