We found that BPA bound directly to the IP3 binding core domain of the IP3 receptor, and BPA competed with IP3 on this site. In addition, overexpression of this domain of the IP3 receptor in Hep3B cells inhibited the stabilization of Nrf2 by BPA. These results clarified that the IP3 receptor is a new target of BPA, and that BPA induces Ca2+ efflux from the endoplasmic reticulum via activation of the IP3 receptor.The creation of an arteriovenous fistula instead of a synthetic vascular graft is a smart decision in hemodialysis patients who do not have a suitable superficial vein. Basilic vein transposition (BVT) is a viable option in most cases, except in patients who do not have a proper basilic vein. In patients with inadequate superficial veins, another source of the autogenous vein is the brachial vein, a deep vein of the upper arm. Most surgeons choose a full medial arm incision to perform brachial vein exploration. We describe a patient in whom BVT was not possible and so brachial vein transposition using skip incisions was performed, with good results.Spinal cord ischemia after open repair of abdominal aortic aneurysm (AAA) is an unpredictable and devastating complication. We present a case report of a patient who developed paraplegia 6 hours after open repair of suprarenal AAA. A 74-yearold man presented with asymptomatic 5.5-cm suprarenal AAA, for which he underwent open repair under general anesthesia. The paraplegia was identified 6 hours after the operation. Postoperative magnetic resonance imaging showed T2 signal hyperintensity and swelling of the spinal cord, which were consistent findings with subacute spinal cord infarction. Although intravenous steroid was administered and lumbar cerebral spinal fluid drainage was instituted, his neurological outcome did not improve. He was discharged after vigorous rehabilitation but still has paraplegia and requires wheelchair for ambulation.Since February 18, 2020, the number of patients with COVID-19 has increased rapidly after the infection was initially confirmed in Daegu. Daegu city subsequently became the largest epicenter of the coronavirus outside China. In the early days of the outbreak of mass infection, Daegu citizens were in various difficult circumstances. Vascular surgery in Daegu was also affected as much as other medical field. Most of elective schedule were canceled, and the vascular surgeons cooperated to utilize the limited medical resources in Daegu region. Fortunately, the citizens of Daegu city could overcome the first crisis because of matured citizenship, sufficient medical resources and the timely-supplied surplus bed for patient isolation. Now all humanity today is interdependent and we are all one community in the pandemic. To overcome pandemic, it is necessary to respect and share experiences in various places at the beginning of the crisis.The coronavirus disease 2019 (COVID-19) pandemic has forever changed the lives of many across the world. Like many others, New Yorkers witnessed their hospital systems become overwhelmed with a massive influx of critically ill patients. selleck products Protocols, workflow, staffing, and individual responsibilities all changed as health care providers scrambled to help where they could. As we see, for the second time this year, a rapid rise in the number of COVID-19 cases in the United States, I wanted to share our experience as vascular surgeons during the first surge from a health care system located in New York City, one of the largest epicenters of the pandemic.Accumulation of reactive oxygen species (ROS) is associated with the development of various diseases. However, the molecular mechanisms underlying oxidative stress that lead to such diseases like autosomal dominant polycystic kidney disease (ADPKD) remain unclear. Here, we observed that oxidative stress markers were increased in Pkd1f/fHoxB7-Cre mice. Forkhead transcription factors of the O class (FOXOs) are known key regulators of the oxidative stress response, which have been observed with the expression of FoxO3a in an ADPKD mouse model in the present study. An integrated analysis of two datasets for differentially expressed miRNA, such as miRNA sequencing analysis of Pkd1 conditional knockout mice and microarray analysis of samples from ADPKD patients, showed that miR-132-3p was a key regulator of FOXO3a in ADPKD. miR-132-3p was significantly upregulated in ADPKD which directly targeted FOXO3 in both mouse and human cell lines. Interestingly, the mitochondrial gene Gatm was downregulated in ADPKD which led to a decreased inhibition of Foxo3. Overexpression of miR-132-3p coupled with knockdown of Foxo3 and Gatm increased ROS and accelerated cyst formation in 3D culture. This study reveals a novel mechanism involving miR-132-3p, Foxo3, and Gatm that is associated with the oxidative stress that occurs during cystogenesis in ADPKD.

The management of steroid resistant nephrotic syndrome (SRNS) is challenging. These guidelines update existing 2009 Indian Society of Pediatric Nephrology recommendations on its management.

To frame revised guidelines on diagnosis and evaluation, treatment and follow up, and supportive care of patients with the illness.

The guidelines combine evidence-based recommendations and expert opinion. Formulation of key questions was followed by systematic review of literature, evaluation of evidence by experts and two face-to-face meetings.

Fourteen statements provide updated advice for defining steroid resistance, and underscore the importance of estimating proteinuria and baseline kidney function, and the need for kidney biopsy and genetic screening. Calcineurin inhibitors are recommended as most effective in inducing remission of proteinuria, the chief factor associated with long-term renal survival. Advice on managing allograft recurrence, congenital nephrotic syndrome, and monitoring and supportive care, including transition of care are described. This revised practice guideline is intended to improve management and patient outcomes, and provide direction for future research.
