The distribution and function of aquaporin 1 and 2 along the kidney in different species

Int. j. morphol; 39 (3), 2021
SUMMARY: Water metabolism in kidney is critical for organisms living in arid environments. In this study, the kidney structure and the expression of AQP1 and AQP2 in Phrynocephalus vlangalii and Camelus bactrianus were studied. It was found that the Phrynocephalus vlangalii has fewer renal corpuscle but ...

Huangkui capsule in combination with leflunomide improves immunoglobulin a nephropathy by inhibiting the TGF-ß1/Smad3 signaling pathway.

Clinics; 76 (), 2021
OBJECTIVES: To investigate the efficacy and potential molecular mechanism of Huangkui capsule in combination with leflunomide (HKL) for the treatment of immunoglobulin A nephropathy (IgAN) METHODS: IgAN rat models were constructed by treating rats with bovine serum albumin, lipopolysaccharide, and tetra...

The renoprotective effects of Heme Oxygenase-1 during contrast-induced acute kidney injury in preclinical diabetic models

Clinics; 76 (), 2021
OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is an important clinical problem that can be aggravated by diabetes mellitus, a major risk factor. However, heme oxygenase-1 (HO-1), a promising therapeutic target, can exert antioxidant effects against CI-AKI. Thus, we investigated the role of HO...

Maternal hypothyroidism during pregnancy alters the function of the retinol-binding protein 4-mediated mitochondrial permeability conversion pore in the kidneys of offspring rats

Clinics; 76 (), 2021
OBJECTIVES To determine the role of the RBP4/PiC/SIRT3 signaling pathway in the opening of the mitochondria permeability transition pore (mPTP) in offspring rats with hypothyroidism during pregnancy. METHODS Sixty Sprague-Dawley (SD) rats were employed in this study. Pregnancy was deemed successful when...

The protective effect of lycopene against oxidative kidney damage associated with combined use of isoniazid and rifampicin in rats

Braz. j. med. biol. res; 54 (8), 2021
It is known that the combined use of antibiotics, such as isoniazid and rifampicin, in the treatment of tuberculosis causes oxidative kidney damage. The aim of this study was to biochemically and histopathologically investigate the effect of lycopene on oxidative kidney damage due to the administration o...

Las hormonas femeninas en fisiología renal: Sensibilidad a la sal y regulación de la proliferación epitelial
Female hormones in renal physiology. Salt sensitivity and regulation of epithelial proliferation

Medicina (B.Aires); 80 (2), 2020
Un tercio de la población mundial tiene niveles anormalmente altos de presión arterial, hipertensión, responsable de casi el 50% de las muertes por accidente cerebrovascular y enfermedad coronaria. La sensibilidad a la sal es un factor de riesgo para la morbilidad y mortalidad cardiovascular y tambié...

Stereological study and analysis of oxidative stress during renal aging in rats

Acta cir. bras; 35 (11), 2020
Abstract Purpose To evaluate renal histological changes by stereology and morphometry and analyze the main markers of oxidative stress in rats undergoing natural aging. Methods Seventy two Wistar rats were divided into six groups of 12 rats each, which were euthanized at 3, 6, 9, 12, 18, and 24 months ...

SGLT-2 inhibitors in diabetes: a focus on renoprotection

SUMMARY Type 2 diabetes mellitus is an important public health problem, with a significant impact on cardiovascular morbidity and mortality and an important risk factor for chronic kidney disease. Various hypoglycemic therapies have proved to be beneficial to clinical outcomes, while others have failed t...

Metabolic and volume status evaluation of hemodialysis patients with and without residual renal function in the long interdialytic interval

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: It is unclear whether residual renal function (RRF) in dialysis patients can attenuate the metabolic impact of the long 68-hour interdialytic interval, in which water, acid, and electrolyte accumulation occurs. Objective: to evaluate serum electrolyte levels, water balance, and a...
