Novel Life Prediction Method of PMMA for Cultural Relics Protection Based on the BP Neural Network.

Poly(methyl methacrylate) (PMMA) is widely used in the preservation and exhibition of cultural relics in museums. Accurately predicting its service life can help avoid many negative effects caused by PMMA aging. To study the change in the yellowing index of PMMA after aging in a UV light environment, an aging experiment was conducted.

Practice of dialysis access interventional nephrology procedures in the Asia-Pacific region: Getting lay of the land.

Aim: This cross-sectional survey aimed to determine the prevalence of Interventional Nephrology (IN) practice amongst nephrologists in the Asia-Pacific Region (APR), specifically related to dialysis access (DA).

Methods: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey.

Stereoselective study of fluoxetine and norfluoxetine across the blood-brain barrier mediated by organic cation transporter 1/3 in rats using an enantioselective UPLC-MS/MS method.

Fluoxetine (FLT) is a widely used antidepressant in clinical practice, which can be metabolized into active norfluoxetine (NFLT) in vivo. The stereoselectivity of FLT and NFLT enantiomers across the blood-brain barrier (BBB) is still to be clarified. In this study, accurate and reliable UPLC-MS/MS enantioselective analysis was established in rat plasma and brain.

Nano bowl-like cobalt-cobalt molybdenum carbide coated by N,P co-doped carbon as an advanced bifunctional oxygen electrocatalyst for rechargeable Zn-air batteries.

Nano bowl-like Co-CoMoC coated by N,P co-doped carbon (Co-CoMoC@NPC) is reported as an electrocatalyst for Zn-air batteries. Co-CoMoC@NPC only needs an overpotential of 210 mV at 10 mA cm for the OER, and the half-wave potential for the ORR is 0.81 V.

Organic Cation Transporters are Involved in Fluoxetine Transport Across the Blood-Brain Barrier and .

Background: The research and development of drugs for the treatment of central nervous system diseases faces many challenges at present. One of the most important questions to be answered is, how does the drug cross the blood-brain barrier to get to the target site for pharmacological action. Fluoxetine is widely used in clinical antidepressant therapy.

Risk of Abdominal Aortic Calcifications among End Stage Renal Disease Patients under Maintenance Haemodialysis.

Calcification of soft tissue and blood vessel wall occurs more frequently in dialyzed patients. The purpose of the present study was to estimate the risk of abdominal aortic calcification among end stage renal disease patients under maintenance haemodialysis. This case-control study was carried out in the Department of Nephrology at National Institute of Kidney Diseases and Urology (NIKDU), Dhaka and National Institute of Cardiovascular Disease and Hospital (NICVD), Dhaka, Bangladesh from January 2013 to December 2014 for a period of two (02) years.

Parvovirus B19-Associated Anemia in Kidney Transplant Recipients: A Single-Center Experience.

Parvovirus B19 (PVB19) has tropism to red blood cell progenitors and can be reactivated after organ transplantation. The aim of study was to describe clinical manifestations, laboratory findings, treatments used, and effectiveness in kidney recipients at Viet Duc hospital. A retrospective descriptive study was performed on 663 kidney recipients who were on regular follow-up from 2000 to 2018.

Association of ORAI1 Genetic Polymorphism with Serum Calcium and Phosphorus Levels in Non-dialysis Chronic Kidney Disease Patients: A Case-control Study.

Background As chronic kidney disease (CKD) is a silent killer, it is now a global concern to find out the possible causes by genetic and biological markers. In the earlier stages of CKD, serum calcium and phosphorus levels fall down later on turned into hypercalcemia and hyperphosphatemia contributing high mortality in CKD. This study aimed to examine the serum calcium and phosphorus levels in non-dialysis CKD patients and healthy controls to find out their association with ORAI1 genetic polymorphism.

Plasma Neutrophil Gelatinase Associated Lipocalin (pNGAL) Level to Identify AKI Early in Patients Undergoing Cardiac Valve Surgery.

Cardiac valve surgery is considered one of the most frequent surgical procedures in which AKI is a common & serious complication. Although serum creatinine is routinely used as a marker of renal function, it poorly reflects the immediate post operative period renal function. Within minutes to few hours after a renal insult, plasma neutrophil gelatinase associated lipocalin (pNGAL) is released.

NGAL (Neutrophil Gelatinase-associated Lipocalin) is an Early Predictor of Acute Kidney Injury after Cardiac Surgery and Variation of NGAL Values in Homogenous Study Subject.

Isolated CABG (coronary artery bypass grafting) has the lowest incidence of AKI (Acute Kidney Injury), followed by valvular surgery and then, combined CABG with valvular surgery. Due to the difference in baseline characteristics and in surgery type, the range of incidence is between 8.9 and 39% based on RIFLE (Risk Injury failure loss end stage kidney disease) or AKIN (Acute Kidney Injury Network) criteria.
