Animal models of kidney transplantation (KTX) are widely used in studying immune response of hosts to implanted grafts. Additionally, KTX can be used in generating kidney-specific knockout animal models by transplantation of kidneys from donors with global knockout of a gene to wild type recipients or vise verse. Dual kidney transplantation (DKT) provides a more physiological environment for recipients than single kidney transplantation (SKT). However, DKT in mice is rare due to technical challenges. In this study, we successfully performed DKT in mice and compared the hemodynamic response and graft function with SKT...

AIMS: Perioperative acute kidney injury (AKI) resulting from renal ischemia reperfusion (IR) is not conducive to the postoperative surgical recovery. Our previous study demonstrated that reactive oxygen species (ROS) transmitted by gap junction (GJ) composed of connexin32 (Cx32) contributed to AKI. However, the precise pathophysiologic mechanisms were unknown. The present study focuses on the underlying mechanisms related to ROS transmitted by Cx32 responsible for AKI aggravation. RESULTS: In a set of vivo studies, renal IR was found to cause severe impairment in renal tissues with massive ROS generation, and occurred contemporaneously with activation of NF-κB/p53/PUMA-mediated mitochondrial apoptosis pathways...

The diabetes mellitus (DM) induces several changes, with substantial increase of reactive oxygen species (ROS). The ROS cause damage to systemic and renal microvasculature, which could be one of the mechanisms involved in the development of diabetic nephropathy (DN). The ROS modulate other substances like the nitric oxide (NO), a vasodilator with important role in the renal function. N-acetylcysteine (NAC) is an antioxidant that acts replenishing intracellular cysteine levels, which is essential for glutathione formation...

The ischemia-reperfusion (I/R) induced skin lesion has been identified as primary cause of pressure ulcers. To date, attempts to prevent pressure ulcers have not produced a significant improvement. Quercetin, one of the most widely distributed flavonoids in fruits and vegetables, exhibits its antioxidant and anti-inflammatory properties against many diseases, including ischemic heart disease, atherosclerosis, and renal injury. In vitro wound scratch assay was first used to assess the function of quercetin in wounding cell model...

OBJECTIVES: To investigate the impact of postoperative time to nadir of estimated glomerular filtration rate on renal functional changes after robot-assisted partial nephrectomy. METHODS: From 2006 to 2015, 287 patients with renal mass who underwent robot-assisted partial nephrectomy in a referral center were analyzed. The cohort was evaluated based on their time to develop nadir: group 1 (no nadir), group 2 (<48 h) and group 3 (≥48 h). The outcome measures were to evaluate the renal function recovery between groups, risk factors for development of nadir ≥48 h, as well as predictors of chronic kidney disease upstaging...

BACKGROUND: Many living kidney donors are still at risk of chronic kidney disease (CKD) 1 year after nephrectomy. Although some donors still experience poor renal function, many exhibit delayed recovery of renal function afterwards. We studied the factors related to delayed recovery of renal function in patients with CKD at 1 year after nephrectomy. METHODS: Patients who underwent donor nephrectomy from March 2006 to April 2014 with a follow-up creatinine study at 1 month, 6 months, 1 year, and after 3 years of follow-up were included in the study...

In recent years, metabolomics using high-performance liquid chromatography (UPLC) has been used to study the metabolic profiles in plasma, urine, stool and tissue in animal model of chronic kidney disease (CKD). In the previous work, we found that traditional Chinese medicine (TCM) "Kidney Flaccidity Compound" (KFC) based on "kidney flaccidity theory" can improve renal function and quality of life of patients with kidney disease. This study aimed to investigate the metabolic profiles in peripheral blood of hemodialysis patients administrated by KFC for 1...

Systemic lupus erythematosus (SLE) is an autoimmune disease posing threats to multiple organs in the human body. As a typical manifestation of SLE, lupus nephritis is characterized by a series of pathological changes in glomerulus as well as accumulation of pathogenic autoreactive IgG with complement in the kidney that dramatically disrupts renal functions. Activation-induced deaminase (AID), which governs both somatic hypermutation (SHM) and class-switch recombination (CSR), has been shown to be essential for the regulation of SLE...

Early allograft dysfunction (EAD) identifies allografts with marginal function soon after liver transplantation (LT) and is associated with poor LT outcomes. The impact of EAD on post-LT renal recovery, however, has not been studied. Data on 69 primary LT recipients (41 with and 28 without history of renal dysfunction) who received renal replacement therapy (RRT) for a median (range) of 9 (13-41) days before LT were retrospectively analyzed. Primary outcome was renal nonrecovery defined as RRT requirement 30 days from LT...

RATIONALE: Anuria is a severe symptom indicating severe kidney damage. Patient recovery from prolonged anuria is rarely reported. PATIENT CONCERNS: A 15-year-old boy received gender- and weight-mismatch heart transplantation (HT) due to dilated cardiomyopathy. He developed severe hypotension, and heart failure 24 hours after surgery, which were relieved by preload reduction treatments. Although, routine examinations did not show any abnormalities in renal function before surgery, anuria occurred 4 days after preload reduction treatments (24-hour urine volume was 23 mL)...

Acute kidney injury (AKI), characterized by a sharp drop in glomerular filtration, continues to be a significant health burden because it is associated with high initial mortality, morbidity, and substantial health-care costs. There is a strong connection between AKI and mechanisms of senescence activation. After ischemic or nephrotoxic insults, a wide range of pathophysiological events occur. Renal tubular cell injury is characterized by cell membrane damage, cytoskeleton disruption, and DNA degradation, leading to tubular cell death by necrosis and apoptosis...

INTRODUCTION: The adenine model of kidney disease typically involves dietary delivery of adenine over several weeks. This model can be variable in its disease progression and can result in significant mortality. In the current study, the amount of adenine delivered to rats was controlled by utilizing oral gavage administration over a short period in an attempt to induce robust renal pathology while addressing variability and viability of the animals. METHODS: Adenine (150 or 200 mg/kg) was administered via oral gavage for 10 consecutive days, and assessed over a total of 20 days...

Background/Aims The research of genes implicated in kidney glomerular function, eliciting cell fate program, is always at the forefront in nephrological studies. Several neurological molecules have been recently the object of study not only for their involvement in the central nervous system differentiation but also for their importance in the functionality of other organs and for mature phenotype, as in kidney. NeuroD, in CNS, is related to two functional roles, the early survival and the differentiation. The aim of our study was to ascertain the presence of NeuroD transcription factor in glomeruli and to understand which targets and mechanisms NeuroD controls...

Pneumonia caused by Pneumocystis jirovecii is an uncommon infection in kidney transplant patients that can have an acute and rapid progression to respiratory failure and death. The period of greatest risk occurs in the first six months after the transplant, and it relates to the high doses of immunosuppression drugs required by patients. However, it may occur late, associated with the suspension of prophylaxis with trimethoprim-sulfamethoxazole.We present two cases of renal transplant patients who had severe hypoxemic respiratory failure due to P...
