Salt intake was significantly associated with annual change in eGFR of -0.11 (95% confidence interval (0.20 - - 0.02) mL/min/1.73m2 per gram of salt, whereas protein intake was not (-0.00001 (-0.01 - 0.01) mL/min/1.73m2 per gram of protein. The effect of salt intake on eGFR slope was significantly mediated by plasma copeptin (crude analysis 77% mediation, and, adjusted analysis 45% mediation), but not by systolic blood pressure. Thus, higher salt, but not higher protein intake may be detrimental in ADPKD. The substantial mediation by plasma copeptin suggests that this effect is primarily a consequence of a salt-induced rise in vasopressin.The popularity of laparoscopy to perform radical hysterectomy has massively increased over the two last decades. However, oncologic outcomes (overall and disease-free survivals) have been found to be better in patients managed by laparotomy compared to laparoscopy, challenging this surgical route. Compared to laparotomy, vaginal access reduces post-operative morbidity, while avoiding potential cancer spread associated with laparoscopy. We describe the procedure of Schauta-Amreich radical vaginal hysterectomy with bilateral salpingo-oophorectomy assisted laparoscopically and associated with a pelvic sentinel lymph node procedure in a 56-year-old woman with a FIGO IB-2 cervical epidermoid carcinoma. A sentinel lymph node (SLN) procedure was first performed by laparoscopy. Radical hysterectomy was prepared by laparoscopy by dividing the infundibulopelvic, round and broad ligaments. The procedure was continued by the vaginal route using the Schuchardt incision. We describe each step of the procedure and provide a video. Histology showed a margin-free resection in both the vagina and parametrium with negative SLNs. This description of the Schauta-Amreich radical vaginal hysterectomy technique with a video file could support the teaching of a procedure which may gain in popularity.The mitochondrial F-ATP synthase is responsible for coupling the transmembrane proton gradient, generated through the inner membrane by the electron transport chain, to the synthesis of ATP. This enzyme shares a basic architecture with the prokaryotic and chloroplast ones, since it is composed of a catalytic head (F1), located in the mitochondrial matrix, a membrane-bound part (FO), together with a central and a peripheral stalk. In this review we compare the structural and functional properties of F-ATP synthase in plant mitochondria with those of yeast and mammals. We also present the physiological impact of the alteration of F-ATP synthase in plants, with a special regard to its involvement in cytoplasmic male sterility. Furthermore, we show the involvement of this enzyme in plant stress responses. Selleck AZ 3146 Finally, we discuss the role of F-ATP synthase in shaping the curvature of the mitochondrial inner membrane and in permeability transition pore formation.The incorporation of mitochondria in the eukaryotic cell is one of the most enigmatic events in the course of evolution. This important organelle was thought to be only the powerhouse of the cell, but was later learnt to perform many other indispensable functions in the cell. Two major contributions of mitochondria in spermatogenesis concern energy production and apoptosis. Apart from this, mitochondria also participate in a number of other processes affecting spermatogenesis and fertility. Mitochondria in sperm are arranged in the periphery of the tail microtubules to serve to energy demand for motility. Apart from this, the role of mitochondria in germ cell proliferation, mitotic regulation, and the elimination of germ cells by apoptosis are now well recognized. Eventually, mutations in the mitochondrial genome have been reported in male infertility, particularly in sluggish sperm (asthenozoospermia); however, heteroplasmy in the mtDNA and a complex interplay between the nucleus and mitochondria affect their penetrance. In this article, we have provided an update on the role of mitochondria in various events of spermatogenesis and male fertility and on the correlation of mitochondrial DNA mutations with male infertility.Recently, functional liposomes modified with versatile polymer and cell-based- biomimetic nanoparticles have emerged as the most advanced lipid-polymer hybrid nanocarriers (LPNs) for drug delivery. This review highlights the advances of these two LPNs in the delivery of active ingredients and fractions from Chinese medicine with promising therapeutic, chemopreventive, or chemosensitive effects. To understand their complete potency, the relationship between the nanoparticle characteristics and their in vitro and in vivo performance characteristics, such as improved physical stability, mucosal penetration, biological and stimuli-responsive feature, and transport across various biological barriers have been discussed. Polymer-modified liposomes and cell-based biomimetic nanoparticles are beneficial for improving absorption, modulating release, targeting and overcoming multidrug resistance, and reducing side effects. The associated challenges, current limitations, and opportunities in this field are also discussed.Objectives Achromobacter xylosoxidans is an emerging pathogen in cystic fibrosis (CF). Relatively little is known about its clinical impact and optimal management. In the present study, the in vitro bactericidal activities of meropenem, either alone or in combination with colistin, levofloxacin, or chloramphenicol, were assessed using A. xylosoxidans strains isolated from CF patients. The synergistic interactions of these combinations were also investigated. Methods Minimal inhibitory concentrations were determined by microbroth dilution. Bactericidal and synergistic effects of the tested antibiotic combinations were assessed by using the time-kill curve technique. Results Based on the time-kill curves, we found that meropenem-colistin combinations have bactericidal and synergistic activities for 24hours against A. xylosoxidans strains both at 1xMIC and 4xMIC. Although synergistic interactions were seen with meropenem-levofloxacin combinations, no bactericidal interactions were observed. Additionally, the meropenem-chloramphenicol combinations were found to be neither bactericidal nor synergistic.
