Abstract
Models validation in QSAR, pharmacophore, docking and others can ensure the accuracy and reliability of future predictions in design and selection of molecules with biological activity. In this study, pyriproxyfen was used as a pivot/template to search the database of the Maybridge Database for potential inhibitors of the enzymes acetylcholinesterase and juvenile hormone as well. The initial virtual screening based on the 3D shape resulted in 2000 molecules with Tanimoto index ranging from 0.58 to 0.88. A new reclassification was performed on the overlapping of positive and negative charges, which resulted in 100 molecules with Tanimoto's electrostatic score ranging from 0.627 to 0.87. Using parameters related to absorption, distribution, metabolism and excretion and the pivot molecule, the molecules selected in the previous stage were evaluated regarding these criteria, and 21 were then selected. The pharmacokinetic and toxicological properties were considered and for 12 molecules, the DEREK software not fired any alert of toxicity, which were thus considered satisfactory for prediction of biological activity using the Web server PASS. In the molecular docking with insect acetylcholinesterase, the Maybridge3_002654 molecule had binding affinity of -11.1 kcal/mol, whereas in human acetylcholinesterase, the Maybridge4_001571molecule show in silico affinity of -10.2 kcal/mol, and in the juvenile hormone, the molecule MCULE-8839595892 show in silico affinity value of -11.6 kcal/mol. Subsequent long-trajectory molecular dynamics studies indicated considerable stability of the novel molecules compared to the controls.AbbreviationsQSARquantitative structure-activity relationshipsPASSprediction of activity spectra for substancesCommunicated by Ramaswamy H.

Abstract
The beneficial effects of kolaviron, a natural biflavonoid from the seeds of Garcinia kola, have been attributed to its antioxidant and anti-inflammatory activities. This study was designed to investigate the renoprotective effect of kolaviron in rat model of diclofenac (DFC)-induced acute renal failure. Thirty-five male Wistar rats were divided into 7 groups of 5 rats each as follows: a control group that received propylene glycol orally and treatment groups that received DFC, DFC recovery, DFC followed by kolaviron at 3 different doses, and kolaviron only. DFC-treated rats showed sluggishness, illness, and anorexia. Their urine contained appreciable protein, glucose, and ketone bodies. Histopathological examination of their kidneys revealed profound acute tubular necrosis. DFC treatment significantly increased levels of plasma creatinine, urea, sodium, chloride, potassium ions, and increased renal tissue activities of superoxide dismutase, catalase, levels of malondialdehyde, and hydrogen peroxide. Fractional excretion of sodium and potassium and renal tissue levels of reduced glutathione and prostaglandin E2 (PGE2) decreased significantly in DFC-treated groups. However, kolaviron administration significantly reduced the toxic effect of DFC on PGE2 release; plasma levels of creatinine, urea, glucose, and electrolytes; and significantly attenuated renal tubular and oxidative damages. Furthermore, the effects of DFC administration on food consumption, water intake, urine output and urine protein, glucose, ketone bodies, and electrolytes were significantly attenuated in animals treated with kolaviron. The results suggested that kolaviron ameliorated DFC-induced kidney injury in Wistar rats by decreasing renal oxidative damage and restoration of renal PGE2 release back to the basal levels.

Abstract
A 16-year-old female patient was admitted to our hospital due to progressive renal dysfunction with an increased serum creatinine (sCr) level of 1.7 mg/dL. Her clinical course without any ocular manifestations and results of drug-induced, lymphocyte-stimulating tests, in addition to a renal histological assessment, initially encouraged us to ascribe the patient’s renal abnormalities to drug-induced acute interstitial nephritis (AIN). Four months later, she started to complain about reduced visual acuity when she was found to have anterior bilateral uveitis despite the recovered renal function with almost constant sCr levels around 0.7 mg/dL. Thus, a diagnosis of tubulointerstitial nephritis and uveitis (TINU) syndrome was finally made. Our case illustrates the difficulties in distinguishing late-onset uveitis TINU syndrome from drug-induced AIN at the time of the renal biopsy, thereby suggesting the importance of a longitudinal follow-up to overcome the potential underdiagnosis of the disease. Several diagnostic conundrums that emerged in this case are also discussed.

Abstract
Acute kidney injury (AKI) is a well-recognized complication of minimal change nephrotic syndrome (MCNS). Previous reports support the concept that AKI associated with MCNS is reversible; however, information regarding the hemodynamic basis of AKI in MCNS is insufficient. We herein describe a case of AKI in a man with MCNS. In this case, monitoring the longitudinal changes in renal perfusion using serial Tc-99m-MAG3 renal scanning was beneficial for evaluating the pathophysiological background associated with the development of AKI. The potential impact of serial renal scanning in MCNS patients with AKI will also be discussed.
