Silencing of Central (Pro)renin Receptor Ameliorates Salt-Induced Renal Injury in Chronic Kidney Disease.

A high-salt diet can aggravate oxidative stress, and renal fibrosis the brain and renal renin-angiotensin system (RAS) axis in chronic kidney disease (CKD) rats. (Pro)renin receptor (PRR) plays a role in regulating RAS and oxidative stress locally. However, whether central PRR regulates salt-induced renal injury in CKD remains undefined.

Hydrophilic Porous Poly(l-Lactic Acid) Nanomembranes: Self-Assembly, and Anti-Biofouling and Anti-Thrombosis Effects.

Hydrophilic PEGylated porous self-assembled nanomembranes (PSANMs) with average thickness and pore diameter of ca. 10 and 20-24 nm were successfully prepared by an emulsification-induced programmable self-assembly strategy. The hydrophilicity, anti-biofouling, and anti-thrombosis properties of PEGylated PSANMs were largely improved in comparison with the nonfunctionalized PSANMs, which could transform into hydrophilic (PEGylated PSANMs, minimum water contact angle: 38.

Hydroxychloroquine-induced renal phospholipidosis resembling Fabry disease in undifferentiated connective tissue disease: A case report.

Background: Fabry disease is a kind of lysosomal storage disease resulting from deficient activity of the lysosomal hydrolase alpha-galactosidase A (GLA). A mutation in the gene leads to a loss of activity of alpha-galactosidase A. Some drugs, such as hydroxychloroquine, can cause pathological changes similar to those usually seen in Fabry disease.

Kidney-targeted triptolide-encapsulated mesoscale nanoparticles for high-efficiency treatment of kidney injury.

Bad water solubility and undesired toxicity of triptolide (TP) still restrict its clinical applications in renal diseases. In this work, well-defined, monodispersed, and uniform-sized TP-encapsulated mesoscale nanoparticles (TP-MNPs) were fabricated through a nanoprecipitation method, which possesses special kidney-targeting capacity, slow-release property, and high-efficiency treatment for renal ischaemia-reperfusion injury (IRI). The TP-MNPs had good cytocompatibility in wide TP concentration (0-500 ng ml) and time ranges (6-24 h).

Renal and cerebral RAS interaction contributes to diabetic kidney disease.

The diabetes mellitus has posed a grave threat on human health, and is bound to result in renal trauma by uncertain mechanisms. Increasing evidences indicated that the activation of the renin-angiotensin system plays a pivotal role during the progression of diabetic kidney disease. In streptozotocin (STZ)-induced type 1 diabetic rat model, the losartan (a selective angiotensin II type 1 (AT1) receptor antagonist) and tempol (4-Hydroxy-TEMPO, reactive oxygen species scavenger) were administrated through intracerebroventricular injection or intragastric gavage.

A stimuli-responsive drug release nanoplatform for kidney-specific anti-fibrosis treatment.

The renoprotective effects of hypoxia inducible-factor (HIF) activators have been demonstrated by improving renal hypoxia in chronic kidney disease. Cobalt chloride is one of the most widely used HIF activators in biomedicine; however, poor kidney targeting and undesirable side effects greatly limit its clinical applications. Here, we report a novel stimuli-responsive drug release nanoplatform in which glutathione (GSH)-modified Au nanoparticles (GLAuNPs) and Co2+ self-assemble into nanoassemblies (GLAuNPs-Co) through coordination interactions between empty orbitals of Co2+ and lone pairs of GSH.

Targeted Ablation of Distal Cerebrospinal Fluid-Contacting Nucleus Alleviates Renal Fibrosis in Chronic Kidney Disease.

The potential function of distal cerebrospinal fluid-contacting nucleus (dCSF-CNs) in chronic kidney disease (CKD) development is poorly understood. We hypothesized that dCSF-CNs might affect the renin-angiotensin system (RAS) in kidney injury progression, with dCSF-CNs ablation potentially alleviating local RAS and renal fibrosis in rats after five-sixths nephrectomy (5/6Nx). Part of rats were randomly administered artificial cerebrospinal fluid (aCSF) intracerebroventricularly (icv), followed by 5/6Nx or sham operation; and other part of rats were administered Cholera toxin B subunit conjugated with saporin (CB-SAP) for dCSF-CNs lesion before 5/6Nx.

Implementing Assisted Peritoneal Dialysis in Renal Care: a Chinese-German Perspective.

Assisted PD (assPD) is an option of home dialysis treatment for dependent end-stage renal patients and worldwide applied in different countries since more than 40 years. China and Germany shares similar trends in demographic development with a growing proportion of elderly referred to dialysis treatment. So far number of patients treated by assPD is low in both countries.

Small-Sized Cationic miRi-PCNPs Selectively Target the Kidneys for High-Efficiency Antifibrosis Treatment.

Small-sized cationic miRi (microRNA-21 inhibitor)-PCNPs (low molecular weight chitosan (LMWC)-modified polylactide-co-glycoside (PLGA) nanoparticles (PLNPs)) with special kidney-targeting and high-efficiency antifibrosis treatment are fabricated through coupling miRi, PLGA, and LMWC. In the miRi-PCNPs, easily degraded miRi is encapsulated in PCNPs and thus prevented from degradation by nuclease. Cytotoxicity, immunotoxicity, and systemic toxicity assays and in vitro and ex vivo fluorescence imaging suggest that PCNPs possess excellent biocompatibility, higher cellular uptake efficiency, and selective kidney-targeting capacity.

Music stimuli lead to increased levels of nitrite in unstimulated mixed saliva.
