Enema de sulcralfato pode prevenir colite em segmentos colônicos sem trânsito fecal?

ABCD (São Paulo, Impr.); 34 (4), 2021
RESUMO - RACIONAL: O estresse oxidativo é um dos principais mecanismos associados à ruptura dos mecanismos de defesa que formam a barreira epitelial cólica e reduz o conteúdo tecidual das proteínas claudina-3 e ocludina principais constituintes das junções de oclusão intercelulares. O sucralfato,...

Expressão de e-caderina e claudina-3 no epitélio cólico após terapia com infliximabe: modelo experimental de colite de exclusão

ABCD (São Paulo, Impr.); 34 (4), 2021
RESUMO - RACIONAL: A etiopatogenia da colite por desuso (DC) ainda não foi totalmente elucidada. As principais teorias consideram que a doença pode estar relacionada ao aumento de bactérias anaeróbias, falta de suprimento de ácidos graxos de cadeia curta (AGCC) e distúrbios imunológicos que se des...

Drogas imunossupressoras afetam os núcleos hipotalâmicos envolvidos na ingestão alimentar ? estudo experimental

ABCD (São Paulo, Impr.); 34 (4), 2021
RESUMO - RACIONAL: Drogas imunossupressoras são indispensáveis para pacientes pós-transplante, diminuindo, significativamente, os riscos de rejeição inerentes a este tipo de procedimento. No entanto, seus efeitos colaterais sobre os núcleos hipotalâmicos envolvidos na regulação da ingestão de a...

Effects of vitamin D administration on nociception and spinal cord pro-oxidant and antioxidant markers in a rat model of neuropathic pain

Braz. j. med. biol. res; 54 (10), 2021
Reactive oxygen species (ROS) are involved in neuropathic pain, a complicated condition after nerve tissue lesion. Vitamin D appears to improve symptoms of pain and exhibits antioxidant properties. We investigated the effects of oral administration of vitamin D3, the active form of vitamin D, on nocicept...

Isolated obesity resistance condition or associated with aerobic exercise training does not promote cardiac impairment

Braz. j. med. biol. res; 54 (10), 2021
Mechanisms involved in cardiac function and calcium (Ca2+) handling in obese-resistant (OR) rats are still poorly determined. We tested the hypothesis that unsaturated high-fat diet (HFD) promotes myocardial dysfunction in OR rats, which it is related to Ca2+ handling. In addition, we questioned whether ...

A novel acrylic resin palatal device contaminated with Candida albicans biofilm for denture stomatitis induction in Wistar rats

J. appl. oral sci; 29 (), 2021
Abstract Denture stomatitis is the most frequent oral lesion in removable prosthesis wearers, with high recurrence rates and a complex treatment. Objective This study describes a protocol to obtain and to contaminate a palatal device with Candida albicans biofilm that could be used for an animal model o...

Hypolipidemic, hipoglycemiant and antioxidant effects of Myrcia splendens (Sw) DC in an animal type 2 diabetes model induced by streptozotocin

We investigated the effects of dichloromethane extract (DME) from Myrcia splendenson alterations caused by type 2 diabetes in the blood and kidney of rats, in order to reduce side effects caused by synthetic drugs. Rats received streptozotocin (60 mg/kg),15 minutes after nicotinamide (120 mg/kg) or water...

Limonium duriusculum (de Girard) Kuntze Exhibits Anti-inflammatory Effect Via NF-κ B Pathway Modulation

HIGHLIGHTS L. duriusculum n-BuOH extract reduces inflammatory responses both in vitro and in vivo. L. duriusculum n-BuOH extract inhibits NF-κB-dependent transcriptional responses. L. duriusculum n-BuOH extract decreases the expression of TNF-α and IL-6 genes....

Calcium homeostasis behavior and cardiac function on left ventricular remodeling by pressure overload

Braz. j. med. biol. res; 54 (4), 2021
Sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) and sarcolemmal Na+/Ca2+ exchanger (NCX1) structures are involved in heart cell Ca2+ homeostasis. Previous studies have shown discrepancies in their function and expression in heart failure. The goal of this study was to evaluate heart function and hypertrophi...

Effects of sympathectomy on myocardium remodeling and function

Clinics; 76 (), 2021
OBJECTIVES: To evaluate the effects of sympathectomy on the myocardium in an experimental model. METHODS: The study evaluated three groups of male Wistar rats: control (CT; n=15), left unilateral sympathectomy (UNI; n=15), and bilateral sympathectomy (BIL; n=31). Sympathectomy was performed by injection...
