Abstract
Membrane-based polyether sulfone (PES) is a potential candidate for hemodialysis because of its properties such as high mechanical strength, thermal stability, and chemical resistance. However, the nature of the hydrophobicity in the PES membrane inhibits their performance in transporting creatinine. In this study, polyethersulfone (PES) membranes were modified using a sulfonation process and the addition of chitosan (CS) and lithium chloride (LiCl) to improve its performance in transporting creatinine. The FTIR spectrum of the modified membrane shows peaks of the sulfonate (-SO2), amine (NH), and hydroxyl (-OH) groups in absorption areas of 1065 cm-1, 1650 cm-1, and 3384 cm-1, respectively, indicating that the membrane SPES/CS-LiCl has been successfully prepared. The modified PES membranes shows a higher porosity, swelling, water absorption, and hydrophilicity than pure PES membrane. The modification of the PES membrane in this study also enhances the ability of the membrane to transport creatinine. In the pure PES membrane, the creatinine clearance is 0.30 mg/dL, while in the SPES/CS-LiCl (5:2) membrane the creatinine clearance is 0.42 mg/dL.

Abstract
The southern harvester termite, Microhodotermes viator, is ecologically important due to its nutrient cycling activities and trophic interactions. Additionally, M. viator appears to have very long-lived colonies, which amplifies their effect on the environment. In order to estimate the longevity of a colony it is necessary to understand colony genetic structure. However, intra- and intercolonial genetic structure and levels of relatedness have not yet been examined in this species, likely due to a lack of microsatellite markers that effectively hybridize in this species. Here we describe the identification and characterization of seven microsatellite loci for M. viator, using an enriched approach and a preliminary test of their suitability for studies of fine-scale population genetic structure. Seven polymorphic loci were identified, none of which deviated from Hardy-Weinberg equilibrium. The loci had an average of 5.8 alleles per locus (range: 2-14) and an overall mean heterozygosity of 0.51 ± 0.3. Across all loci, population level pairwise F ST values showed significant genetic differentiation. The loci described and preliminary genetic data presented here provide an invaluable tool for future studies of population structure and longevity in M. viator colonies.
