1. Fibroblast morphology, growth rate and gene expression in facial melasma
Abstract Background: In addition to melanocytic hyperfunction, changes are observed in the upper dermis of melasma, and fibroblasts play a central role in collagen synthesis and pigmentation induction. Objective: To explore the morphology, growth rate, and gene expression profile of fibroblasts from the skin with melasma in comparison to fibroblasts from t

2. Molecular mechanism of benign biliary stricture inhibition by rosiglitazone-activated peroxisome proliferator-activated receptor gamma
SUMMARY OBJECTIVE: The aim of this study was to investigate whether rosiglitazone-activated peroxisome proliferator-activated receptor gamma can inhibit the occurrence of benign biliary stricture and further elucidate the relevant molecular signaling mechanism. METHODS: The primary cultured rat biliary fibroblasts following experiments were performed using

3. Linseed Oil Nanoemulsion with Pluronic® F127 Loaded with Betulinic Acid: Preparation, Rheology, MTT Assay and in vitro Release Kinetics
The main objective of this work was to develop a nanoemulsion based on linseed oil and betulinic acid, stabilized with Pluronic F127 and polyglycerol polyricinoleate, for anticancer applications. The nanoemulsions were synthesized by ultrasound and evaluated for in vitro cytotoxicity, particle size, polydispersity index, zeta potential, morphology, encapsula

4. Viability of fibroblasts from "Curraleiro Pé Duro" cattle after different cryopreservation protocols
RESUMO A raça tropicalmente adaptada Curraleiro Pé Duro (CPD) possui grande rusticidade e capacidade de produção. A técnica de criopreservação de células somáticas permite estocar, por tempo indeterminado, o material genético. O objetivo deste trabalho é avaliar a viabilidade de fibroblastos, pós-criopreservação, em protocolos diferentes. Foi u

5. Expression of OPN3 in fibroblasts, melanocytes, and keratinocytes of skin with facial melasma in comparison with unaffected adjacent skin
Abstract Sporotrichosis is a subcutaneous mycosis that affects humans and animals, with a typically subacute or chronic evolution, caused by Sporothrix spp., a dimorphic fungus. Although the cutaneous form is the most frequent presentation, the ocular involvement has been more frequently diagnosed in endemic areas, affecting mainly children and the elderly.

6. Study of Dosage-Dependent Effects of Cytostatic Drugs Using a Fibroblast Cell Culture of the Human Nasal Mucosa
Abstract Introduction Knowing a concentration at which cytostatic drugs are toxic for the nasal fibroblasts will enable the use cytostatic drugs in the clinical practice to prevent excessive cicatrization. Objective To determine the cytostatic concentrations of mitomycin С, doxorubicin, and 5-fluorouracil affecting nasal mucosa fibroblasts. Methods We

7. Antioxidant-mediated protective role of Hericium erinaceus (Bull.: Fr.) Pers. against oxidative damage in fibroblasts from Friedreich’s ataxia patient
Abstract Friedreich’s ataxia (FRDA) is a progressive neuromuscular disorder caused by substantial decrease of mitochondrial protein frataxin responsible for biogenesis of iron-sulphur clusters and protection from oxidative damage. In this study, we investigated the antioxidant activities of a standardized aqueous extract from fruiting bodies of Hericium er

8. In vitro anti-aging activities of ginkgo biloba leaf extract and its chemical constituents
Abstract To determine in vitro anti-aging activity and identify the active chemical constituents in Ginkgo leaf extracts. The antioxidant properties of Ginkgo biloba leaves extracts were evaluated using 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging and 2,2’-azino-bis (3-ethylbenzothiazoline)-6 sulfonic acid radical (ABTS) scavenging assays. The i

9. Mitomycin C in the Endoscopic Treatment of Laryngotracheal Stenosis: Systematic Review and Proportional Meta-Analysis
Abstract Introduction Mitomycin C is a natural antibiotic that has been used to inhibit the proliferation of fibroblasts in scar tissue. Objective To evaluate the effectiveness and safety of topical Mitomycin C as an adjuvant in the endoscopic treatment of laryngotracheal stenoses. Data synthesis A systematic review of experimental or observational st

11. Co-transfection of hepatocyte growth factor and truncated TGF-β type II receptor inhibit scar formation
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still capable of binding to TGF-β, thereby blocking the TGF-β signaling
