99 ± 0.17%), primary spermatocytes (10.49 ± 0.74%), round spermatids (34.80 ± 1.57%), elongated spermatids (23.59 ± 2.02%), spermatozoa (21.56 ± 1.86%), Sertoli cells (7.53 ± 1.23%) and Leydig cells (0.04 ± 0.03%). However, spermatocytes II were not identified. This is due to the low proportions of these cells, related to their very short lifespan. Likewise, the very low number of Leydig cells observed is probably due to the damage caused during the aspiration stage. This study showed that fine-needle aspiration is an efficient method to describe cytologically normal testicular populations, a cornerstone for future research aimed to study abnormal spermatogenesis and to correlate it to cytological proportion of germ cells.In an era of evidence-based medicine and dialysis performance measures, there is strong motivation to find specific, objective, quantifiable, and reproducible parameters to characterize the clinical condition of chronic kidney disease patients and to present population-wide statistics that may describe quality of care in dialysis centers. Yet, in the last three decades, several studies demonstrated that while parameters including Kt/V urea, serum phosphorus, parathyroid hormone, serum cholesterol fulfill all these criteria, efforts to optimize these lab parameters failed to improve survival on dialysis. VT107 cost However, subjective assessments of nutrition including subjective global assessment and malnutrition-inflammation score, while not ideally suited for statistical analysis and not optimal from the point of view of scientific methodology due to their general, semi-quantifiable, subjective nature have, nevertheless, proved themselves as some of the strongest predictors of clinical outcomes in the dialysis population. Where does this paradox leave us? We propose that a deeper understanding of relevance of these variables in the dialysis population may improve appreciation of the clinical situation of individual patients and may result in a paradigm shift from dialysis adequacy to quality dialysis.Renal interstitial fibrosis (RIF) is a pathological process that fibrotic components are excessively deposited in the renal interstitial space due to kidney injury, resulting in impaired renal function and chronic kidney disease. The molecular mechanisms controlling renal fibrosis are not fully understood. In this present study, we identified Nuclear protein 1 (Nupr1), a transcription factor also called p8, as a novel regulator promoting renal fibrosis. Unilateral ureteral obstruction (UUO) time-dependently induced Nupr1 mRNA and protein expression in mouse kidneys while causing renal damage and fibrosis. Nupr1 deficiency (Nupr1-/- ) attenuated the renal tubule dilatation, tubular epithelial cell atrophy, and interstitial collagen accumulation caused by UUO. Consistently, Nupr1-/- significantly decreased the expression of type I collagen, myofibroblast markers smooth muscle α-actin (α-SMA), fibroblast-specific protein 1 (FSP-1), and vimentin in mouse kidney that were upregulated by UUO. These results suggest that Nupr1 protein was essential for fibroblast activation and/or epithelial-mesenchymal transition (EMT) during renal fibrogenesis. Indeed, Nupr1 was indispensable for TGF-β-induced myofibroblast activation of kidney interstitial NRK-49F fibroblasts, multipotent mesenchymal C3H10T1/2 cells, and the EMT of kidney epithelial NRK-52E cells. It appears that Nupr1 mediated TGF-β-induced α-SMA expression and collagen synthesis by initiating Smad3 signaling pathway. Importantly, trifluoperazine (TFP), a Nupr1 inhibitor, alleviated UUO-induced renal fibrosis. Taken together, our results demonstrate that Nupr1 promotes renal fibrosis by activating myofibroblast transformation from both fibroblasts and tubular epithelial cells.The i-motif DNA, also known as i-DNA, is a non-canonical DNA secondary structure formed by cytosine-rich sequences, consisting of two intercalated parallel-stranded duplexes held together by hemi-protonated cytosine-cytosine+ (CC+ ) base pairs. The growing interest in the i-DNA structure as a target in anticancer therapy increases the need for tools for a rapid and meaningful interpretation of the spectroscopic data of i-DNA samples. Herein, we analyzed the circular dichroism (CD) and thermal difference UV-absorbance spectra (TDS) of 255 DNA sequences by means of multivariate data analysis, aiming at unveiling peculiar spectral regions that could be used as diagnostic features during the analysis of i-DNA-forming sequences.Invited for the cover of this issue are Andrea Pannwitz, Sylvestre Bonnet and co-workers at Leiden University and Johns Hopkins University.

Instead of typical methods, calculating the SF-36 Global Score has recently become an increasingly common reporting approach. However, numerical changes lack clear clinical relevance. The minimal clinically important difference (MCID) is useful for interpreting changes in functional scores by defining the smallest change patients may perceive as clinically meaningful. The aim of this study is to determine the MCID of the SF-36 Global Score in orthopedic oncology patients, which has not been reported to date. Three-hundred ten patients who underwent surgery and completed two surveys during postoperative follow-up were reviewed. The two most common methods for calculating the SF-36 Global Score were used (1) anchor-based methods and receiver operating characteristic analysis based on one-half of the SD of change score and standard error of measurement at baseline and; (2) distribution-based methods. Using anchor-based methods, the MCIDs of SF-36 Global Scores #1 and #2 were 2.7 (area under the curve [AUC] = 0.85) and 2.5 (AUC = 0.79) for improvement, and -1.5 (AUC = 0.81) and -0.6 (AUC = 0.83) for deterioration, respectively. Using distribution-based methods, the MCIDs of SF-36 Global Scores #1 and #2 were 4.1 and 4.4 by half SD, and 4.1 and 4.5 by standard error of measurement, respectively. Our findings provide benchmark values, which can serve as a reference for future studies in musculoskeletal tumor patients using the SF-36 Global Score as a single measure for HRQoL.
