93 years. At the time of the study, 15 patients had died and 29 were alive. EBER-CISH positivity was found in 13 patients. Four showed strong EBER-CISH expression and nine showed weak expression. EBER-CISH positivity was not statistically related to any of the prognostic factors or to overall survival. Discussion Although EBER-CISH positivity showed no significant relation with prognostic factors, it was observed in one-third of all cases. Therefore, we think that the Epstein-Barr virus may have a role in the pathogenesis of upper urinary tract urothelial carcinomas. This finding needs to be supported by larger studies.The red alga Chondria armata is known to produce and contain a rich diversity of secondary metabolites, such as domoic acid-related alkaloids and triterpene polyethers. Our investigation on red alga C. armata from Kagoshima coast, Japan, resulted in the isolation of two new triterpene polyethers, bandokorols A (1) and B (2). The structures of these compounds were determined based on spectroscopic data such as infrared (FTIR), 1H-NMR, APT, 1H-1H-COSY, HSQC, HMBC, NOESY and FAB mass spectrometry (HRFABMS). The anticancer potentials of these compounds were tested against adult T-cell leukaemia (ATL), S1T cells and their IC50 values are reported here.Inflammation is a major determinant for the progression of chronic kidney disease (CKD). NF-κB is a master transcription factor upregulated in CKD that promotes inflammation and regulates apoptosis and vascular remodeling. Coleonol We aimed to modulate this pathway for CKD therapy in a swine model of CKD using a peptide inhibitor of the NF-κB p50 subunit (p50i) fused to a protein carrier [elastin-like polypeptide (ELP)] and equipped with a cell-penetrating peptide (SynB1). We hypothesized that intrarenal SynB1-ELP-p50i therapy would inhibit NF-κB-driven inflammation and induce renal recovery. CKD was induced in 14 pigs. After 6 wk, pigs received single intrarenal SynB1-ELP-p50i therapy (10 mg/kg) or placebo (n = 7 each). Renal hemodynamics were quantified in vivo using multidetector computed tomography before and 8 wk after treatment. Pigs were then euthanized. Ex vivo experiments were performed to quantify renal activation of NF-κB, expression of downstream mediators of NF-κB signaling, renal microvascular density, inflammation, and fibrosis. Fourteen weeks of CKD stimulated NF-κB signaling and downstream mediators (e.g., TNF-α, monocyte chemoattractant protein-1, and IL-6) accompanying loss of renal function, inflammation, fibrosis, and microvascular rarefaction versus controls. All of these were improved after SynB1-ELP-p50i therapy, accompanied by reduced circulating inflammatory cytokines as well, which were evident up to 8 wk after treatment. Current treatments for CKD are largely ineffective. Our study shows the feasibility of a new treatment to induce renal recovery by offsetting inflammation at a molecular level. It also supports the therapeutic potential of targeted inhibition of the NF-κB pathway using novel drug delivery technology in a translational model of CKD.Sepsis-associated acute kidney injury (s-AKI) has a staggering impact in patients and lacks any treatment. Incomplete understanding of the pathogenesis of s-AKI is a major barrier to the development of effective therapies. We address the gaps in knowledge regarding renal oxygenation, tubular metabolism, and mitochondrial function in the pathogenesis of s-AKI, utilizing the cecal ligation and puncture (CLP) model in mice. At 24 hours after CLP, renal oxygen delivery was reduced, however, fractional oxygen extraction was unchanged, suggesting inefficient renal oxygen utilization despite decreased GFR and filtered load. To investigate underlying mechanisms, we examined temporal changes in mitochondrial function and metabolism at 4 and 24 hours after CLP. At 4 hours after CLP, markers of mitochondrial content and biogenesis were increased in CLP kidneys, but mitochondrial oxygen consumption rates (OCR) were suppressed in proximal tubules. Interestingly, at 24 hours, proximal tubular mitochondria displayed high respiratory capacity, but with decreased mitochondrial content, biogenesis, fusion and ATP levels in the CLP kidneys, suggesting decreased ATP synthesis efficiency. We further investigated metabolic reprogramming after CLP and observed reduced expression of fatty acid oxidation enzymes, but increased expression of glycolytic enzymes at 24 hours. However, assessment of functional glycolysis revealed lower glycolytic capacity, glycolytic reserve and compensatory glycolysis in CLP proximal tubules, which may explain their susceptibility of injury. In conclusion, we demonstrate significant alterations in renal oxygenation, tubular mitochondrial function and metabolic reprogramming in s-AKI which may play an important role in the progression of injury and recovery from AKI in sepsis.Background Systemic lupus erythematosus (SLE) is characterized by hypertension that results from chronic renal inflammation and dysautonomia in the form of dampened vagal tone. In health, the vagus nerve regulates inflammatory processes through mechanisms like the cholinergic anti-inflammatory pathway; so in the case of SLE, reduced efferent vagus nerve activity may indirectly affect renal inflammation, and therefore hypertension. In this study, we sought to investigate the impact of disrupting vagal neurotransmission on renal inflammation and hypertension in the setting of chronic inflammatory disease. Methods Female SLE (NZBWF1) and control (NZW) mice were subjected to a right unilateral cervical vagotomy or sham surgery and 3 weeks later were implanted with indwelling catheters to measure blood pressure. Indices of splenic and renal inflammation, as well as renal injury, were assessed. Results Unilateral vagotomy blunted SLE-induced increases in mean arterial pressure, albumin excretion rate, and glomerulosclerosis. This protection was associated with reduced splenic T cells and attenuated SLE-induced increases in renal pro-inflammatory mediators. Conclusion In summary, these data indicate that unilateral vagotomy reduces renal inflammation and reduces blood pressure in SLE mice. The vagus nerves have myriad functions and perhaps other neuroimmune interactions compensate for the ligation of one nerve.
