Minoxidil and human platelet lysate (HPL) are commonly used to treat patients with hair loss. However, the roles of HPL versus minoxidil in hair follicle biology largely remain unknown. Here, we hypothesized that bulge and dermal papilla (DP) cells may express specific genes, including Kras, Erk, Akt, Shh and β-catenin after exposure to minoxidil or HPL. The mouse hair follicles were isolated on day 10 after depilation and bulge or DP regions were dissected. The bulge and DP cells were cultured for 14days in DMEM/F12 medium...

BACKGROUND: The incidence of post-endoscopic sphincterotomy (ES) bleeding is reportedly 2.0-5.0 %. Among various hemostatic methods, endoclip therapy is an effective modality in gastrointestinal bleeding. However, endoclip application for post-ES hemorrhage has not been widely studied, partly because of the difficulty in placing of clips using a duodenoscope. A cap-fitted forward-viewing gastroscope can easily visualize the major papilla and overcome the technical difficulty in applying endoclips...

Dens invaginatus is a developmental anomaly resulting in an infolding of the enamel organ into the dental papilla prior to calcification of the dental tissues. The invagination predisposes the tooth for the development of dental caries. Conventional radiographs do not provide detailed information concerning the three-dimensional image, which would help the clinician in making a confirmatory diagnosis and planning the treatment before undertaking the actual treatment. This report describes a case where Oehlers type II dens invaginatus was diagnosed with the help of spiral computed tomography...

BACKGROUND: When primary root canal therapy fails, periapical lesions can be retreated with or without surgery. Root canal retreatment is a non-surgical procedure that involves removal of root canal filling materials from the tooth, followed by cleaning, shaping and obturating of the canals. Root-end resection is a surgical procedure that involves exposure of the periapical lesion through an osteotomy, surgical removal of the lesion, removal of part of the root-end tip, disinfection and, commonly, retrograde sealing or filling of the apical portion of the remaining root canal...

The fish fauna in the State of Acre represents 10·7% of all fish species recorded from Brazil, but, despite this, there are few fish parasite studies in this area. The recent expansion of fish farming in Acre prompted a need for helminthological studies of the most commonly consumed fish species in the area, Pimelodus blochii (Pimelodidae). The aim of this study was to analyse the helminth fauna of P. blochii from the Acre and Xapuri Rivers in Northwestern Brazil. Numerous nematodes were collected from the intestine and two species of the family Atractidae were identified: Rondonia rondoni Travassos, 1920 and Orientatractis moraveci n...

Soft tissue dehiscence around dental implant has frequently been observed and it may lead to poor oral hygiene, especially around crowns that exhibit contours with prominent convexity. The present case demonstrates a peri-implant mucosal dehiscence coverage with modified semilunar coronary positioned flap (CPF) in #15 and 16. A semilunar partial-thickness incision was performed 7-10 mm apical from the facial gingival margin. Then, intrasulcular partial-thickness incision was tunneled to the semilunar incision...

BACKGROUND: Dental stem cells in combination with implant materials may become an alternative to autologous bone transplants. For tissue engineering different types of soft and rigid implant materials are available, but little is known about the viability and the osteogenic differentiation of dental stem cells on these different types of materials. According to previous studies we proposed that rigid bone substitute materials are superior to soft materials for dental tissue engineering...

A 39-year-old woman presented with a history of recurrent abdominal pain. She had been hospitalized for mild pancreatitis 3 years ago. Her vital signs were stable, and other tests were normal. Radiography showed a well-defined spherical duodenal mass measuring 3.2 cm × 5.0 cm (Figure 1 [A], white arrows). On endoscopy, the lesion appeared as a submucosal mass immediately anterior to the duodenal papilla (Figure 1 [B]). Endoscopic ultrasonography (US) revealed a double-layered wall, and an inner echogenic and outer hypoechoic layer (Figure 1 [C])...

Nematodes belonging to genus Hedruris Nitzsch, 1821 (Nematoda: Hedruridae) were found in the stomach of the freshwater fish Oligosarcus jenynsii (Günther, 1864) (Characidae) from a shallow eutrophic lake in Argentina. Morphological comparisons with congeneric relatives showed that these nematodes belong to a new species, for which H. bifida n. sp. is proposed. Hedruris bifida n. sp. can be distinguished from its congeners by the following combination of characters: bifid deirids, absence of precloacal papillae and nine pairs of postcloacal papillae and non-mammillated eggs...

The success of dental implant therapy in the esthetic zone requires not only functional osseointegration but also favorable esthetic results. The greatest challenge in the esthetic zone is to establish harmony, balance, and continuity of gingival form between implant restorations and the adjacent natural teeth. In the esthetic zone, a localized ridge defect or loss of a peri-implant papilla is common and can be corrected via soft tissue augmentation. This case report describes a novel surgical technique using connective tissue grafts via an apical pouch to increase soft tissue volume over an alveolar ridge defect or around natural teeth or implants in the maxillary anterior area...

The case reports presented in this article describe a surgical approach for improving root coverage and regenerative parameters in deep intrabony defects associated with buccal gingival recession. A mandibular canine and a maxillary premolar were treated. The surgical technique consisted of a connective tissue graft (CTG) that was placed and sutured at the inner surface of a coronally advanced envelope flap (CAF), thickening the buccal soft tissue wall of the most coronal extension of the intrabony defect and treated with biomaterials as scaffold...

Melatonin is a widely known hormone in animals. Since melatonin was discovered in plants, more and more studies highlight its involvement in a wide range of physiological processes including plant development and stress responses. Many advances have been made in the terms of melatonin-mediated abiotic stress resistance and innate immunity in plants, focusing on model plants such as rice and Arabidopsis. In this study, 7 melatonin synthesis genes were systematically analyzed in cassava. Quantitative real-time PCR showed that all these genes were commonly regulated by melatonin, flg22, Xanthomonas axonopodis pv manihotis (Xam) and hydrogen peroxide (H2O2)...

BACKGROUND: The presence of an interproximal gingival (central) papilla is of prime importance and an essential component of a harmonious and pleasing smile. The aim of this study was to determine the association between the presence of a central papilla and embrasure and crown morphology. METHODS: The study was conducted on 200 periodontally healthy patients. Parameters such a central papilla presence, gingival thickness, crown length, crown width, contact surface, radiographic assessment of bone crest to contact point (BC-CP), and interdental width (IDW) in maxillary central incisor embrasure morphology were recorded...
