Human blood and urine mutagenicity of 3-(5-nitro-2-furyl)acrylic acid (5-NFA) was analysed by using Salmonella typhimurium indicator strains TA100 AND TA98 and the cytogenetic analysis of human peripheral lymphocytes. 8 human volunteers were given doses of 1 g 5-NFA per os. The mutagenic effect in blood was analysed after 0, 0.5, 1, 2 and 4 h, in urine after 0, 2 and 4 h. Cytogenetic analysis was done 0, 24 and 72 h after administration of 5-NFA. The experiment was repeated with 3 volunteers in the course of 96 h. When each of 8 volunteers consumed 1 g of 5-NFA, the mutagenicity was observed in 6 blood samples 1 h after exposure for strain TA98 (doubled number or revertants) and in all urine samples taken between the 2nd and 6th hours for both strains used. 7 volunteers given 10 mg 5-NFA in wine (2 sets) showed no mutagenicity of blood or urine for TA100 or TA98 indicator strains. These results are believed to indicate an enhanced elimination of 5-NFA from the human body.

An autopsy case with tubular obstruction by impacted swollen blebs due to ischemic acute kidney injury.

Department of Nephrology, Japan Community Healthcare Organization Sendai Hospital, 981-3281, Sendai, Miyagi, Japan.
Background: Oliguric acute kidney injury (AKI) is one of the critical conditions which needs emergent treatment due to the lack of the capacity of excreting toxins and fluids, and plasma membrane bleb formation is considered as one of the characteristic morphologic alterations in ischemic AKI in both animal models and human. We present here an autopsy case with clear electron microscopy images capturing a definitive instance of blebbing in ischemic AKI.
Case Presentation: A 66-year-old man was admitted for oliguric AKI with nephrotic syndrome (NS).

Anti-vascular endothelial growth factor-associated thrombotic microangiopathy (aVEGF-TMA) was recently discovered in patients with malignant tumors. Four aVEGF-TMA patients diagnosed by renal biopsy between 2018 and 2022 were identified, and all were females aged 30-62 years (mean age, 47 years). Two patients with malignant gastrointestinal stromal tumors who received sunitinib were analyzed.

Introduction: Delayed sleep-wake phase disorder(DSWPD)is a serious threat to the physical and mental health. There are some problems with current clinical treatment methods, and exercise is an alternative to chronotherapy. Therefore, we aimed to study the effects of two different exercise methods, aerobic and resistance, on sleep, melatonin, inflammatory factors and mood in college students with DSWPD.

Background: Insulin resistance often occurs in patients with chronic kidney disease (CKD) owing to mineral and bone metabolism disorders. Fibroblast growth factor (FGF)-23 and soluble klotho (s-KL) play crucial roles in linking CKD with mineral and bone metabolism.
Objective: This study aimed to examine the relationship between insulin resistance and FGF-23 and s-KL in patients with non-diabetic pre-dialysis patients with CKD.
