Neuroprotective Potential of a Novel Soluble Guanylate Cyclase Stimulator the Riociguat Alone or in a Combination Manner with Resveratrol in Experimental Stroke Model in Rats

Int. j. morphol; 42 (4), 2024
SUMMARY: In this study we aimed to examine the effect of novel vasodilatory drug Riociguat co-administration along resveratrol to recover neurodegeneration in experimental stroke injury. For that purpose, thirty-five adult female rats were divided into five groups (Control, MCAO, MCAO + R, MCAO + BAY, MC...

Histomorphometric analysis of the soleus muscle in different phases of ischemic stroke in an animal model

HSJ; 14 (), 2024
Objective: To analyze the muscle mass and cross-sectional area of the muscular fiber of the hemiparetic soleus in an animal model, in order to identify the muscular adaptations that occur in ischemic stroke.Method: Twelve Rattus norvegicus were divided into 2 groups: stroke group (n=6) and control group ...

Synthesis and evaluation of 2-phenylamino-1, 4-naphthoquinones derivatives as potential hypoglycaemic agents

Braz. j. biol; 84 (), 2024
Due to the severe side effects revealed by most of the currently used antidiabetic medicines, search for finding new and safe drugs to manage diabetes is continued. Naphthoquinones possessing strong antioxidant properties have been employed as candidates for diabetes therapy. Present study is aimed at fi...

Ultrasonic neuromodulation as a new therapy for spasticity in an animal model of spastic cerebral palsy

Acta cir. bras; 39 (), 2024
Purpose: This study aimed to evaluate a new therapeutic option for the spasticity using ultrasound neuromodulation in an animal model of spastic cerebral palsy. Methods: Thirty-two adult male Wistar rats were randomly distributed in: negative control (NC); positive control (PC); untreated model (UTM); a...

Anterior-interrupted and posterior-continuous suture technique improved the success rate of kidney transplantation model in rats

Acta cir. bras; 39 (), 2024
Purpose: This study aimed to introduce and evaluate two new microvascular anastomosis techniques compared to the conventional method in a rat renal transplant model. Methods: Using a Fisher-to-Lewis rat kidney transplantation model, the renal artery anastomosis was performed using the interrupted (I) su...

Interação B1R/TLR4 como mecanismo de resposta inflamatória e sua implicação na barreira hematoencefálica em modelo de glioblastoma
B1R/TLR4 interaction as a mechanism of inflammatory response and its implication on the blood-brain barrier in glioblastoma model

A família dos receptores de cininas compreende dois subtipos, sendo o B1R aquele em tem como um de seus agonistas fisiológicos a des-Arg9 -BK (DBK). O receptor B1 tem baixa expressão ou está até mesmo ausente em condições fisiológicas normais, podendo ser induzido por vários estímulos, como o p...

Diferentes concentrações de sódio nos fluidos têm impacto variável no dano cerebral, pulmonar e renal no acidente vascular encefálico isquêmico experimental
Different sodium concentrations in fluids have variable impact on brain, lung and kidney damage in experimental ischemic stroke

Introdução: A administração de fluidos é muitas vezes realizada no Acidente Vascular Encefálico isquêmico (AVEi) agudo. Permanecem controvérsias em relação ao efeito de diferentes concentrações de sódio em fluidos administrados após AVEi, bem como seu impacto em órgãos a distância. Nosso...

Comparison of Bone Graft Preparations to Treat a Critical Bone Defect on a Rodent Animal Model

Abstract Objective Although autologous bone grafting is the most widely used treatment for bone defects, the most effective preparation remains unclear. This animal study aimed to compare different autologous bone grafting preparation for the treatment of rats calvaria critical bone defect. Methods 122...

Characterization of the Masquelet Induced Membrane Technique in a Murine Segmental Bone Defect Model

Abstract Objective To reproduce in an animal model the surgical technique of Masquelet used in the treatment of critical bone defects and to analyze the characteristics of the membrane formed around the bone cement. Methods A 10mm critical defect was created in the femoral shaft of 21 Sprague-Dawley ra...

Thermal Injury Protocol to Study Healing, With and Without Infection, in Guinea Pig (Cavia porcellus) Model

Int. j. morphol; 41 (4), 2023
SUMMARY: Experimental healing studies in humans are complex and difficult to replicate in vitro. Hence, animal models are needed to study the different stages involved. The guinea pig (Cavia porcellus) is a model close to human physiology, including the lack of vitamin C synthesis, a precursor of collage...
