Biochemical and histopathological evaluations of chronic renal failure rats treated with pluripotent human stem cells

Abstract Regeneration of damaged kidney cells using stem cells is the current research approach in the treatment of chronic renal failure (CRF). In the present study, the histopathological and biochemical techniques were used to evaluate stem cells' (SCs) role in treatment of CRF. Sixty-four rats were di...

Suppression of diabetes-induced renal inflammatory cell infiltration by metformin associated with the amelioration of renal injury biomarkers

Int. j. morphol; 40 (4), 2022
SUMMARY: Diabetes and hypertension account for the majority of chronic kidney injury cases that can lead to renal failure. The link between the leukocytes common antigen (CD45) and diabetic kidney disease (DKD) with and without metformin incorporation in an animal model has not been investigated before. ...

The effects of L-carnitine on gastrointestinal contractility and histological changes in rat intestinal ischemia-reperfusion Injury

Int. j. morphol; 40 (5), 2022
SUMMARY: Ischemia-reperfusion (I/R) of the small intestine causes serious abdominal pathologies including tissue dysfunction and organ failure. L-carnitine (L-C), a powerful antioxidant, may help lessen the severity of these pathological effects since it plays a key role in energy metabolism. In this wor...

Effect of melatonin on peripheral nerve damage resulting from tibial defect in rats

Int. j. morphol; 40 (4), 2022
SUMMARY: Peripheral nerve damage (PNI) can cause demyelination, axonal degeneration and loss of motor and sensory function. Melatonin with its antioxidative effect, has been reported to reduce scar formation in nerve injury, take a role in repair process by suppressing fibroblast proliferation in the dam...

Modelo de hipotermia experimental en murinos para estudios de lesión medular
Experimental hypothermia murine model for spinal cord injury studies

Introducción: Los ensayos de hipotermia sistémica en murinos son costosos, debido a la complejidad de los sistemas. El objetivo de este estudio fue evaluar si el modelo de hipotermia sistémica exógena utilizado en nuestro laboratorio para la hipotermia ocular es útil para reducir significativamente ...

Protocol paper: kainic acid excitotoxicity-induced spinal cord injury paraplegia in Sprague-Dawley rats

Biol. Res; 55 (), 2022
BACKGROUND: Excitotoxicity-induced in vivo injury models are vital to reflect the pathophysiological features of acute spinal cord injury (SCI) in humans. The duration and concentration of chemical treatment controls the extent of neuronal cell damage. The extent of injury is explained in relation to loc...

Aβ promotes CD38 expression in senescent microglia in Alzheimer's disease

Biol. Res; 55 (), 2022
BACKGROUND: In Alzheimer's disease (AD), the neuroinflammatory response mediated by the activation of senescent microglia is closely related to energy dysmetabolism. However, the mechanism underlying the interaction between the energy metabolism of aging microglia and neuroinflammation remains unclear. M...

Acupuncture attenuates comorbid anxiety- and depressive-like behaviors of atopic dermatitis through modulating neuroadaptation in the brain reward circuit in mice

Biol. Res; 55 (), 2022
Atopic dermatitis (AD) is highly comorbid with negative emotions such as anxiety and depression. Although acupuncture has demonstrated efficacy in AD, its influence on comorbid anxiety and depression remains unclear. We sought to explore the impact and mechanisms of action of acupuncture on comorbid anxi...

Mice as an animal model for the study of adipose tissue and obesity

Int. j. morphol; 39 (6), 2021
SUMMARY: The study of adipose tissue has gained increasing importance in the biomedical area due to its implications for health and obesity. Obesity is a situation of great concern mainly in the Western world due to its high prevalence and morbidity. Experimental studies on obesity often need a model whe...

Quantitative evaluation of the regenerated dura mater in a decompressive skull trepanation model in rats

Int. j. morphol; 39 (6), 2021
SUMMARY: Regeneration of the dura mater following duraplasty using a collagen film, a chitosan film, or a combination of both with gelatin, was studied in a craniotomy and penetrating brain injury model in rats. Collagen autofluorescence in the regenerated dura mater was evaluated using confocal microsco...
