Abstract

Congenital anomalies of the kidney and urinary tract (CAKUT) represent structural and functional urinary system malformations and take place as one of the most common congenital malformations with an incidence of 1:500. Ureteral obstruction-induced hydronephrosis is associated with renal fibrosis and chronic kidney diseases in the pediatric CAKUT. We aimed to construct interaction network of previously bioinformatically associated miRNAs with CAKUT differentially expressed genes in order to prioritize those associated with fibrotic process and to experimentally validate the expression of selected miRNAs in CAKUT patients compared to control group. We constructed interaction network of hsa-miR-101-3p, hsa-miR-101-5p and hsa-miR-29c-3p that showed significant association with fibrosis. The top enriched molecular pathway was extracellular matrix-receptor interaction (adjusted p =.0000263). We experimentally confirmed expression of three miRNAs (hsa-miR-29c-3p, hsa-miR-101-3p and hsa-miR-101-5p) in obstructed ureters (ureteropelvic junction obstruction and primary obstructive megaureter) and vesicoureteral reflux. The hsa-miR-29c-3p was shown to have lower expression in both patient groups compared to controls. Relative levels of hsa-miR-101-5p and hsa-miR-101-3p showed significant positive correlations in both groups of patients. Statistically significant correlation was observed between hsa-miR-101 (-3p and -5p) and hsa-miR-29c-3p only in the obstructed group. The significant downregulation of anti-fibrotic hsa-miR-29c-3p in obstructive CAKUT could explain activation of genes involved in fibrotic processes. As miRNAs are promising candidates in therapeutic approaches our results need further measurement of fibrotic markers or assessment of extent of fibrosis and functional evaluation of hsa-miR-29c.

Abstract

It has been a persistent challenge to develop eco-friendly packaging cellulose film providing the required multiple barrier properties whilst simultaneously contributing to a circular economy. Typically, a cellulosic film made from nanocellulose materials presents severe limitations, such as poor water/moisture resistance and lacking water vapour barrier properties, related primarily to the hydrophilic and hygroscopic nature of cellulose. In this work, alkyl ketene dimer (AKD) and starch, both eco-friendly, non-toxic, cost-effective materials, were used to achieve barrier properties of novel cellulose-calcium carbonate composite films regenerated from paper components, including paper waste, using ionic liquid as solvent. AKD and starch were applied first into the ionic cellulose solution dope mix, and secondly, AKD alone was coated from hot aqueous suspension onto the film surface using a substrate surface precooling technique. The interactions between the AKD and cellulose film were characterised by Fourier-Transform Infrared Spectroscopy (FTIR) and X-ray Diffraction (XRD) showing the formation of a ketone ester structure between AKD and the hydroxyl groups of cellulose. The presence of calcium carbonate particles in the composite was seen to enhance the cellulose crystallinity. The initial high-water vapour and oxygen transmission rates of the untreated base films could be decreased significantly from 2.00 to 0.14 g m(-2) d(-1), and 3.85 x 10(2) to 0.45 x 10(2) cm(3) m(-2) d(-1), respectively. In addition, by applying subsequent heat treatment to the AKD coating, the water contact angle was markedly increased to reach levels of superhydrophobicity (>150 degrees, and roll-off angle < 5 degrees). The resistance to water absorption, grease-permeation, and tensile strength properties were ultimately improved by 41.52%, 95.33%, and 127.33%, respectively, compared with those of an untreated pure cellulose film. The resulting regenerated cellulose-calcium carbonate composite-based film and coating formulation can be considered to provide a future bio-based circular economy barrier film, for example, for the packaging, construction and agriculture industries, to complement or replace oil-based plastics. publishedVersion

Abstract

Cannulation technique has the potential to impact arteriovenous fistula (AVF) junction. The aim of this research was to determine the impact of cannulation technique on the length of the functioning AVFs in older adult patients on hemodialysis. The study included 110 participants with fistula thrombosis who had used area technique or rope ladder technique. Biochemical parameters, gender, demographic, and clinical variables were determined. Patients who used the area cannulation technique differed significantly from patients using the rope ladder technique with regard to duration of hemodialysis (p < 0.001), outcome of the AVF revision (p = 0.045), and positioning of the anastomosis (p = 0.013). The group that used the area cannulation technique had a longer duration of hemodialysis, proximal anastomoses, and more successful revisions of AVFs. Key Words: Arteriovenous fistula, older adult patients, cannulation technique, area cannulation, rope ladder technique, functionality., The incidence and prevalence rates of end stage renal disease (ESRD) are highest in patients age 65 years and older (Saran et al., 2016; United States Renal Data System [USRDS], [...]

Abstract

The increased demand for cheap, biodegradable, renewable, and recyclable fibers with exceptional properties positioned jute (Corchorus capsularis L. and Corchorus olitorius L.) in the second place (after cotton) in the natural fiber world market. Multicellular jute fibers are comprised of three main components: cellulose, lignin, and hemicelluloses having a wide variety of functional groups capable of binding different water pollutants. However, such groups are not easily accessible due to the presence of a hydrophobic surface layer (consisting of pectins, waxes, and fats) that could be removed by applying simple alkali and oxidative modifications. Moreover, fibers’ activation using different chemical agents or grafting of functional groups on their surfaces results in enhanced fiber sorption properties, and hence adsorption potential for various water pollutants. This chapter provides an overview of the possibility of the application of raw and chemically modified jute fibers as an eco-friendly adsorbent for heavy metals and dyes as the most frequent water pollutants. Special attention has been paid to the binding mechanism of the pollutants and differently functionalized jute adsorbents. The last section of this chapter represents one step toward both the circular economy approach and sustainable development, in terms of reusing and revalorization of solid waste with adsorbed pollutants. Permanent collection and reuse of pollutant saturated jute adsorbents have promising multi-positive effects on the economy as well environment, including reducing its quantity, saving energy, and its utilization as raw material for producing new hybrid materials which is in line with the Circular Economy Package (2020).

Abstract

International audience; Treatment of wastewater pollution is a critical issue in the context of growing population and industrialization. Actual treatment methods are expensive and not fully effective and rely on fossil fuel-derived chemicals, thus calling for alternative adsorption methods on natural materials such as hemp. Industrial hemp (Cannabis sativa Linn) is a high-yielding annual industrial crop harvested for its fiber from the stem and its oil from the seeds. Hemp is a multi-purpose plant with great potential because of its many uses, such as building materials, textiles, paper, food and beverage, automotive, cosmetics, and medicine. Wastewater treatment is another innovative application. Indeed, the past decade has shown an explosion in the study of hemp-based materials for the biosorption of metal ions from effluents, demonstrating that industrial hemp is one of the most promising materials for environmental applications. Hemp products can be used as biosorbents in granular or felt forms or to prepare non-conventional activated carbons, both used in biosorption-oriented processes. In this chapter, after a brief description of biosorption, the use of different types of hemp-based materials that can be used as pollutant biosorbents is described.&nbsp

Abstract

In this paper, the influence of the catalytic oxidation using water soluble and stable nitroxyl radical 2,2´,6,6´-tetramethylpiperidine-1-oxyl (TEMPO) on structure and properties of cotton fibers was studied. In particular, the selective TEMPO-mediated oxidation has become very interesting way for introduction of functional groups into cellulose fibers with the aim to obtain oxycellulose fibers with specific properties. Unmodified and modified fibers were characterized in terms of weight loss values, introduced functional groups and crystallinity index. Also, oxidized fibers were characterized in terms of the sorption, morphological, and physico-mechanical properties. The TEMPO-oxidized cotton fibers show a minimum increase of fineness (from 1.32 to 1.28 dtex) and increase of crystallinity index (up to 91.9%), while the tensile strength of fibers decreases (up to 10.82 cN/tex). By the TEMPO-mediated oxidation of cotton fibers significant amount of carboxyl groups (up to 0.795 mmol/g cell) can be introduced into cellulose fibers. Introduced hydrophilic carboxyl groups increases the sorption properties of oxidized fibers, that can be used directly or for further chemical modification.

Abstract

Background Congenital anomalies of the kidney and urinary tract (CAKUT) are a common cause of progressive chronic kidney disease that may lead to end-stage renal disease and renal replacement therapy in childhood. Altered expression or activity of matrix metalloproteinases (MMPs) have been found in CAKUT. The MMP-1, -3, and -8 polymorphisms studied here are located in the gene promoters and alter expression. Our aim was to investigate associations of MMP polymorphisms, solely and in haplotypes, with CAKUT in children. Methods A case-control study with 101 pediatric patients and 281 controls was performed. The MMP-1 (-1607 1G/2G), -3 (5A/6A), and -8 (-799 C/T) genotypes were determined by PCR-restriction fragment length polymorphism. Results We found statistically significant associations of MMP-3 5A/6A polymorphism (p Conclusions MMP-3 genotypes and MMP-3 and -1 haplotypes encompassing either MMP-8-799C or T alleles were associated with CAKUT and obstructive uropathies in pediatric patients Still, functional and association studies are needed to elucidate evident roles of MMPs in CAKUT Keywords CAKUT * Obstructive uropathy * Matrix metalloproteinase * Gene * Polymorphisms, Introduction Congenital anomalies of the kidney and urinary tract (CAKUT) include a variety of anatomical and histological malformations during faulty embryonic development, implying both obstructive and functional abnormalities All together, [...]
