Combined effects of MSU crystals injection and high fat-diet feeding on the establishment of a gout model in C57BL/6 mice

Adv Rheumatol; 60 (), 2020
Abstract Objective: Gout is characterized by inflammatory arthritis with hyperuricaemia and deposition of monosodium urate (MSU) crystals in the joints. Several animal models have been proposed based on MSU crystals injection or high-fat diet feeding; however, neither hyperuricaemia model nor acute gout...

Preconditioning with L-Ala-Gln reduces the expression of inflammatory markers (TNF-α, NF-κB, IL-6 and HO-1) in an injury animal model of cerebrovascular ischemia in Meriones unguiculatus (gerbils)

Acta cir. bras; 35 (6), 2020
Abstract Purpose To evaluate the neuroprotective effect of L-alanyl-glutamine in a gerbil model of brain ischemia-reperfusion injury based on immunohistochemical quantification of pro-inflammatory and cell activation biomarkers (TNF-α, NF-κB, IL-6 and HO-1). Methods Male gerbils weighing 10...

Development and application of a swine model for training ultrasonography-guided central venous access

Rev. Col. Bras. Cir; 47 (), 2020
ABSTRACT Introduction: simulation based teaching is a powerful tool in medical education, allowing hands on practice under a controlled environment and with repeated maneuvers. Central venous access venipuncture is one of the most frequent procedures carried out in the hospital setting, due to its vari...

Impact of topical nifedipine on wound healing in animal model (pig)

J. vasc. bras; 19 (), 2020
Abstract Background The human skin is an extremely sophisticated and evolved organ that covers the whole body. External agents or the patient's own diseases can cause skin injuries that can challenge healthcare professionals and impose high social, economic and emotional costs. Objectives To evaluate t...

Chronic aerobic exercise associated to low-dose L-NAME improves contractility without changing calcium handling in rat cardiomyocytes

Braz. j. med. biol. res; 53 (3), 2020
Nitric oxide (NO) inhibition by high-dose NG-nitro-L-arginine methyl ester (L-NAME) is associated with several detrimental effects on the cardiovascular system. However, low-dose L-NAME increases NO synthesis, which in turn induces physiological cardiovascular benefits, probably by activating a protectiv...

Assessment of Experimental Models for Obtaining Adipose-Derived Mesenchymal Stem Cells

Abstract Creating experimental models for obtaining stem cells from adipose tissue is necessary to elucidate their peculiar features. Objective: This study proposed a reliable reproducible and consistent experimental model for obtaining mesenchymal stem cells from adipose tissue. Material and Method: Lin...

The effect of natural products in animal models of temporomandibular disorders

J. appl. oral sci; 28 (), 2020
Abstract Treatment of temporomandibular disorders (TMD) is a challenge for health care professionals. Therefore, new approaches have been investigated, such as the use of natural products. Objective This systematic review aims to summarize the natural products used in treatment of experimental models o...

Quorum Sensing Interfering Strategies and Their Implications in the Management of Biofilm-Associated Bacterial Infections

Abstract The bacterial species employ various types of molecular communication systems recognized as quorum sensing for the synchronization of differential gene expression to regulate virulence traits and biofilm formation. A variety of quorum sensing inhibitors; molecules that interfere with quorum sens...

Abstract Objective: To investigate the expression of High Mobility Group Box 1 (HMGB1) and Heat Shock Protein-70 (HSP-70) during orthodontic tooth movement (OTM) after (-)- Epigallocatechin-3-Gallate (EGCG) in East Java Green Tea (Camelia Sinensis) Methanolic Extract (GTME) administration in vivo. Mate...

Effect of the Application of Chlorella Vulgaris Ointment to the Number of Fibroblast Cells as an Indicator of Wound Healing in the Soft Tissue of Pig Ears

Abstract Objective: To analyze the clinical and histological condition of Chlorella vulgaris ointment extract smearing on wound healing. Material and Methods: The sample consisted of 9 pigs by making 4 incisions on the pig's right ear measuring 2cm x 1cm and applying Chlorella vulgaris ointment in 3 co...
