The aim of the study was to compare 3 mm mini-laparoscopy (mini LP), standard 5 mm laparoscopy (LP) and open surgery for pediatric pyeloplasty in a single center.

Patients who underwent pyeloplasty from 1997 to 2017 at Hospital Sant Joan de Déu were prospectively collected. Demographic data, clinical, surgical and radiological variables were assessed. A multivariate logistic regression analysis was performed in order to identify risks for surgical complications, urinary leak and need for redo-surgery.

340 pyeloplasties were performed in this period 197 open, 30 LP and 113 mini LP. Independent risk factors for surgical complications in a multivariate logistic regression model were LP (vs mini LP, OR = 3.95; 95% CI 1.13-13.8), higher differential renal function (each point more increases the risk 6%; 95% CI 1-11%), older children (every year increases the risk 1.11 times; 95% CI 1.002-1.225). Open surgery, pelvis diameter or the use of different stents were not risk factors. This model had an 80% PPV and a 92% NPV. LP (OR = 4.65; 95% CI 1.08-19.96) and longer surgical time (OR = 1.014; 95% CI 1.003-1.025) were independent risk factors for urinary leak. Higher pelvis diameter (OR = 0.93; 95% CI 0.87-0.99) and the use of external stents were independent protective risk factors for urinary leak (OR = 0.09; 95% CI 0.01-0.72). We have not found independent risk factors for redo-surgery in a multivariate logistic regression model.

mini LP can be safely and effectively used to perform pyeloplasty in pediatric patients of all ages.

As extremely important component of plants, animal cell membrane and microbes cytoderm, polysaccharides have been applied as medications, foods and cosmetics stemming from their prominent biological functions and minor side-effects. Recent studies indicate that polysaccharides exert biological effects also through epigenetic mechanism. Through the intervention of DNA methylation, histone modification, and non-coding RNA, polysaccharides participatate in regulation of immunity/inflammation, glucose and lipid metabolism, antioxidant damage and anti-tumor, which presents novel mechanism of polysaccharide exerting various functions. In this review, the latest advances in the biological functions of dietary polysaccharides via epigenetic regulations were comprehensively summarized and discussed. From the view point of epigenetic regulation, investigating the relationship between polysaccharides and biological effects will enhance our understandings of polysaccharides and also means huge breakthrough of molecular mechanism in the polysaccharide research fields. The paper will provide important reference to these investigators of polysaccharide research and expand the applications of dietary polysaccharides in the functional food developments.Angiotensin I-converting enzyme 2 (ACE2), type II transmembrane serine protease 2 and 4 (TMPRSS2 and TMPRSS4) are important receptors for SARS-CoV-2 infection. In this study, the full-length tree shrewACE2 gene was cloned and sequenced, and its biological information was analyzed. The expression levels of ACE2, TMPRSS2 and TMPRSS4 in various tissues or organs of the tree shrew were detected. The results showed that the full-length ACE2 gene in tree shrews was 2,786 bp, and its CDS was 2,418 bp, encoding 805 amino acids. Phylogenetic analysis based on the CDS of ACE2 revealed that tree shrews were more similar to rabbits (85.93%) and humans (85.47%) but far from mice (82.81%) and rats (82.58%). In silico analysis according to the binding site of SARS-CoV-2 with the ACE2 receptor of different species predicted that tree shrews had potential SARS-CoV-2 infection possibility, which was similar to that of rabbits, cats and dogs but significantly higher than that of mice and rats. In addition, various tissues or organs of tree shrews expressed ACE2, TMPRSS2 and TMPRSS4. Among them, the kidney most highly expressed ACE2, followed by the lung and liver. The esophagus, lung, liver, intestine and kidney had relatively high expression levels of TMPRSS2 and TMPRSS4. In general, we reported for the first time the expression of ACE2, TMPRSS2 and TMPRSS4 in various tissues or organs in tree shrews. Our results revealed that tree shrews could be used as a potential animal model to study the mechanism underlying SARS-CoV-2 infection.In the diagnostic process of dry eye disease, the detection of inflammatory activity is critical in order to evaluate the risk of progression and immunologic shift of the disease, to predict patient response to treatment, and to design an efficient therapeutic strategy, including artificial tear replacement, punctal occlusion or anti-inflammatory therapy.Even if it is difficult to quantify, some indicators of the presence of inflammation are collectible during the examination of the ocular surface in a first-line clinical setting. This review presents and critically discusses the assessment of inflammation in dry eye disease in clinical practice.Primary hippocampal neuronal cells were used to establish cell model of cerebral ischemia under oxygen-glucose deprivation (OGD) treatment. After the cell model was pre-treated with short hairpin (sh)-circ_NLRP1 or mmu-miR-199b-3p inhibitor, LDH release and cell apoptosis were detected by LDH kit and TUNEL staining, respectively, while the expression of NLRP3 pyroptosis-related makers was analyzed through immunofluorescence (IF) assay and Western blot, respectively. The binding sites between circ_NLRP1 and mmu-miR-199b-3p were predicted and further validated by Dual Luciferase Reporter assay. Additionally, mitogen-activated protein kinase (MAPK) pathway was also analyzed by means of Western blot assay. Neuronal cells under OGD conditions released less lactate dehydrogenase (LDH) and showed less apoptosis status by silencing circ_NLRP1. In addition, gasdermin D (GSDMD)-N immunofluorescence staining showed weaker fluorescence intensity and decreased expression of pyroptosis-related mediators. We further found that mmu-miR-199b-3p-inhibitor could alter the effects of sh-circ_NLRP1 on hippocampal neuronal cells. In addition, in this process, extracellular signal-regulated kinase (ERK)/EGR1 pathway was also significantly affected. In conclusion, OGD stimulation induced neuronal damage and pyroptosis through enhancing circ_NLRP1 expression and further downregulating mmu-miR-199b-3p levels. The present study provided a novel insight for understanding the potential mechanism of ischemia-induced neuronal damage and for developing new drugs for treating brain ischemia damage.Histone modification influences gene expression. Among histone modifications, H3K27me3 is associated with downregulation of nearby genes via chromatin compaction. In Arabidopsis thaliana, a subset of JUMONJI C DOMAIN-CONTAINING PROTEIN (JMJ) proteins play a critical role in removal of H3K27me3 during plant development or in response to environmental cues. However, the regulation of H3K27me3 demethylase gene expression is not yet fully characterized. In this study, we computationally characterized the expression patterns of JMJ H3K27me3 demethylase genes using public transcriptome datasets created across plant development and after various environmental cues. Consistent with the available transcriptome datasets, GUS staining validated that JMJ30 was highly expressed in the L1 layer of the shoot apical meristem. Furthermore, expression data for panel of five H3K27me3 demethylase genes revealed JMJ30 to be the most highly affected by abiotic and biotic stress. In addition, JMJ30 expression was variable between Arabidopsis thaliana accessions. Finally, the expression of a JMJ30 orthologue from the related species Arabidopsis halleri, AhgJMJ30, fluctuated under field conditions. Taken together, our results suggest that transcriptional changes of H3K27me3 demethylase genes may play key roles in development and environmental responses.Epigenetic clocks have been widely used to predict disease risk in multiple tissues or cells. Their success as a measure of biological ageing has prompted research on the connection between epigenetic pathways of ageing and the socioeconomic gradient in health and mortality. However, studies examining social correlates of epigenetic ageing have yielded inconsistent results. We conducted a comprehensive, comparative analysis of associations between various dimensions of socioeconomic status (SES) (education, income, wealth, occupation, neighbourhood environment, and childhood SES) and eight epigenetic clocks in two well-powered US ageing studies The Multi-Ethnic Study of Atherosclerosis (MESA) (n = 1,211) and the Health and Retirement Study (HRS) (n = 4,018). In both studies, we found robust associations between SES measures in adulthood and the GrimAge and DunedinPoAm clocks (Bonferroni-corrected p-value less then 0.01). In the HRS, significant associations with the Levine and Yang clocks were also evident. learn more These associations were only partially mediated by smoking, alcohol consumption, and obesity, which suggests that differences in health behaviours alone cannot explain the SES gradient in epigenetic ageing in older adults. Further analyses revealed concurrent associations between polygenic risk for accelerated intrinsic epigenetic ageing, SES, and the Levine clock, indicating that genetic risk and social disadvantage may contribute additively to faster biological aging.Here we compare mineral accumulation and global gene expression patterns between two metal hyperaccumulator plants - Noccaea japonica, originating from Ni-rich serpentine soils, and Noccaea caerulescens (ecotype Ganges), originating from Zn/Pb-mine soils - under excess Ni conditions. Significant differences in the accumulation of K, P, Mg, B, and Mo were explained by the expression levels of specific transporters for each mineral. We previously showed that total Ni accumulation in the whole plant is higher in N. caerulescens than in N. japonica. Here we found a similar tendency for Fe under excess Ni; however, the expression of iron-regulated transporter 1 (IRT1), which encodes the primary Fe uptake transporter and causes excess Ni uptake in Arabidopsis thaliana, was higher in N. japonica. NjIRT1 has a point mutation at Asp100, which is essential for Fe transport, and so might lack its Fe and possibly Ni transport function. Noccaea japonica might have lost its IRT1 function, which would prevent excess Ni uptake via IRT1 in Ni-rich soils, and come to rely on other transporters.Teleost fish such as Danio rerio (zebrafish) have been successfully used in biomedical research since decades. Genetically altered fish lines obtained by state-of-the-art genetic technologies are serving as well-known model organisms. In Europe, following Directive 2010/63/EU, generation, breeding, and husbandry of new genetically altered lines of laboratory animals require governmental state approval in case pain, suffering, distress, or long-lasting harm to the offspring derived by breeding of these lines cannot be excluded. The identification and assessment of pain, distress, or harm, according to a severity classification of mild, moderate, severe, or humane endpoint, became a new challenging task for all scientists, animal technicians, and veterinarians for daily work with laboratory zebrafish. In this study, we describe the performance of the assessment of welfare parameters of selected pathologic phenotypes and abnormalities frequently found in laboratory fish facilities based on veterinary, biological, and physiological aspects by using a dedicated score sheet.
