INTRODUCTION: Acetone cyanohydrin (ACH) is a toxic substance present in cassava roots (Manihot esculenta Crantz) which results from enzymatic hydrolysis of linamarin. Long-term consumption is associated with 2 neurological disorders: konzo and tropical ataxic neuropathy. Previous studies have evaluated behavioural alterations linked to ACH consumption, but the toxic effects of this substance on physiological processes remain unknown. METHOD: 32 male Wistar rats were assigned to 4 experimental groups (n=8 per group): a vehicle group (0...

Cisplatin is an effective chemotherapeutic agent and widely used in treatment of various solid organ malignancies, including head and neck, ovarian, and testicular cancers. However, the induction of acute kidney injury (AKI) is one of its main side effects. Leukotriene B4 receptor 1 (BLT1) mediates the majority of physiological effects of leukotriene B4 (LTB4), a potent lipid chemoattractant generated at inflammation sites, but the role of the LTB4-BLT1 axis in cisplatin-induced AKI remains unknown. Here we found upregulated LTB4 synthesis and BLT1 expression in the kidney after cisplatin administration...

Key physiological functions of the liver, including glucose and lipid metabolism, become disturbed in the setting of non-alcoholic fatty liver disease (NAFLD) and may be associated with a systemic inflammatory 'milieu' initiated in part by liver-secreted cytokines and molecules. Consequently, the pathophysiological effects of NAFLD extend beyond the liver with a large body of clinical evidence demonstrating NAFLD to be independently associated with both prevalent and incident cardiovascular disease (CVD), chronic kidney disease (CKD) and type 2 diabetes mellitus (T2DM)...

BACKGROUND: Genetically engineered pigs could provide a source of kidneys for clinical transplantation. The two longest kidney graft survivals reported to date have been 136 and 310 days, but graft survival >30 days has been unusual until recently. METHODS: Donor pigs (n=4) were on an α1,3-galactosyltransferase gene-knockout (GTKO)/human complement regulatory protein (CD46) background (GTKO/CD46). In addition, the pigs were transgenic for at least one human coagulation regulatory protein...

Percutaneous coronary intervention (PCI) in patients with advanced chronic kidney disease (CKD) is challenging due to frequent presence of complex calcified lesions and the very high risk of contrast-induced nephropathy (CIN). We report a strategy of "zero contrast" PCI, guided by intravascular imaging and physiology, performed in three patients with advanced CKD in whom severe calcification necessitated rotational atherectomy (RA) to facilitate and optimize PCI. This approach resulted in safe and successful PCI while preserving renal function...

Osteopontin (Opn), a multifunctional extracellular matrix protein, is implicated in the pathogenesis of various inflammatory disorders. Under physiologic conditions, its expression is restricted to certain tissues including bone and kidney tubule. However, cellular activation during disease development induces Opn expression in various immune cells. In this study, using Opn-EGFP knock-in (KI) mice we found that CD8α+ T cells in the intestinal tissues, including Peyer's patch, lamina propria and epithelium, express Opn under steady state conditions...

Ultrasound evaluation of the ovaries is an important element of the gynaecological examination. Although it is a well-established method used for many domestic animals, it is an uncommon procedure in cats. This article describes the technical requirements, the examination procedure, and the sonographic appearance of the physiological ovary in the cat. The examination can be performed with the cat in lateral position or dorsal recumbency. Usually the ovaries are found caudal to the kidneys which serve as lead structure...

The β2 adrenergic receptor (β2AR) increases intracellular Ca(2+) in a variety of cell types. By combining pharmacological and genetic manipulations, we reveal a novel mechanism through which the β2AR promotes Ca(2+) mobilization (pEC50 = 7.32 ± 0.10) in non-excitable human embryonic kidney (HEK)-293S cells. Down-regulation of Gs with sustained cholera toxin pre-treatment and the use Gs-null HEK293 (ΔGs-HEK293) cells generated using the CRISPR/Cas9 system, combined with pharmacological modulation of cAMP formation revealed a Gs-dependent but cAMP-independent increase in intracellular Ca(2+) following β2AR stimulation...

Increases in plasma osmolality activates the paraventricular nucleus of the hypothalamus (PVN) which in turn mounts a physiological response by increasing the release of arginine vasopressin and sympathetic nerve activity to end organs such as the kidney. The PVN expresses an abundance of purinergic receptors including P2X2 receptors. In the present study, we sought to determine 1) whether P2X2-expressing PVN neurons are activated by hypertonic saline or hypertonic mannitol and 2) what effects P2X receptor blockade has on sympathetic nerve activation mediated by a hyperosmotic stimulus...

Avian basal metabolic rate (BMR) and summit metabolic rate (Msum) vary in parallel during cold acclimation and acclimatization, which implies a functional link between these variables. However, evidence suggests that these parameters may reflect different physiological systems acting independently. We tested this hypothesis in white-throated sparrows (Zonotrichia albicollis) acclimated to two temperatures (-8° and 28°C) and two diets (0% and 30% cellulose). We expected to find an uncoupling of Msum and BMR where Msum, a measure of maximal shivering heat production, would reflect muscle and heart mass variation and would respond only to temperature, while BMR would reflect changes in digestive and excretory organs in response to daily food intake, responding to both temperature and diet...

We generated and studied CLIC1 null (C1KO) mice to investigate the physiological role of this protein. C1KO and matched wild-type (WT) mice were studied in two models of acute toxic tissue injury. CLIC1 expression is upregulated following acute injury of WT kidney and pancreas and is absent in C1KOs. Acute tissue injury is attenuated in the C1KOs and this correlates with an absence of the rise in tissue reactive oxygen species (ROS) that is seen in WT mice. Infiltration of injured tissue by inflammatory cells was comparable between WT and C1KOs...

The purpose of this review is to summarize our knowledge and understanding of the physiological importance and the mechanisms underlying flow-activated proximal tubule transport. Since the earliest micropuncture studies of mammalian proximal tubule, it has been recognized that tubular flow is an important regulator of sodium, potassium, and acid-base transport in the kidney. Increased fluid flow stimulates Na(+) and HCO3(-) absorption in the proximal tubule via stimulation of Na/H-exchanger isoform 3 (NHE3) and H(+)-ATPase...

Polycystic kidney disease (PKD) proteins are trans-membrane proteins that have crucial roles in many aspects of vertebrate development and physiology, including the development of many organs as well as left-right patterning and taste. They can be divided into structurally-distinct PKD1-like and PKD2-like proteins and usually one PKD1-like protein forms a heteromeric polycystin complex with a PKD2-like protein. For example, PKD1 forms a complex with PKD2 and mutations in either of these proteins cause Autosomal Dominant Polycystic Kidney Disease (ADPKD), which is the most frequent potentially-lethal single-gene disorder in humans...

Uropathogenic Escherichia coli (UPEC) are the primary causative agents of urinary tract infections. Some UPEC isolates are able to infect renal proximal tubule cells, and can potentially cause pyelonephritis. We have previously shown that to fulfill their physiological roles renal proximal tubule cells accumulate high concentrations of α-ketoglutarate (KG) and that gene cluster c5032-c5039 contribute to anaerobic utilization of KG by UPEC str. CFT073, thereby promoting its in vivo fitness. Given the importance of utilizing KG for UPEC, this study is designed to investigate the roles of two transporters KgtP and C5038 in KG utilization, their transcriptional regulation, and their contributions to UPEC fitness in vivo...

FTY720, a new chemical substance derived from the ascomycete Isaria sinclairii, is used for treating multiple sclerosis, renal cancer, and asthma. Sphingosine 1-phosphate (S1P) is a bioactive sphingolipid metabolite and exists in red blood cells. FTY720 is a synthetic S1P analog which can block S1P evoking physiological effects. Recently studies show that S1P was participating in activated inflammation cells induced renal injury. The objective of this study was to assess the protective effect of FTY720 on kidney damage and the potential mechanism of FTY720 which alleviate podocyte injury in chronic kidney disease...
