Coronally advanced flap in conjunction with platelet-rich fibrin-assisted immediate management of residual gingival defect following surgical excision of recurrent pyogenic granuloma in the maxillary esthetic segment.

Exophytic gingival lesions are more frequently encountered intraorally, out of which few are reactive in nature. Pyogenic granuloma (PG) is one of the commonly occurring reactive benign mucocutaneous lesions; exact etiopathogenesis remains unclear. Although surgical excision is the treatment of choice, sometimes it may induce residual soft defect formation which further creates an esthetic problem, root sensitivity, etc.

Diode Laser and Periodontal Regeneration-Assisted Management of Implant Complications in Anterior Maxilla.

Dental implant is being considered successful if the patient is pleased with both of its functional and esthetic outcome. As implant complications (such as peri-implantitis, inappropriate implant position, wrong angulation, and implant location too close to anatomical structures) have been frequently encountered in dental practice, therefore, thorough knowledge to manage such complications is the key prerequisite to prevent the failure of implant. The present case report discussed the etiology, diagnosis of early peri-implantitis, and periodontal abscess with their successful management through periodontal regeneration and diode laser-assisted therapy.

Investigating the structural integrity of Bovine serum albumin in presence of newly synthesized metallosurfactants.

Bovine Serum Albumin is major transport protein and is often used as a drug carrier in body organs. Knowledge of its binding with metallosurfactant can significantly influence the biodistribution of metallodrugs. Current work demonstrated a facile method to prepare four different double chained metallosurfactants containing Fe, Co, Ni and Cu as part of their counter ion.

Drug repurposing for aging research using model organisms.

Many increasingly prevalent diseases share a common risk factor: age. However, little is known about pharmaceutical interventions against aging, despite many genes and pathways shown to be important in the aging process and numerous studies demonstrating that genetic interventions can lead to a healthier aging phenotype. An important challenge is to assess the potential to repurpose existing drugs for initial testing on model organisms, where such experiments are possible.

Changes in the neuropeptide content of Biomphalaria ganglia nervous system following Schistosoma infection.

Background: Molluscs, including snails, are prone to parasite infection, which can lead to massive physiological and behavioural changes, yet many of the molecular components involved remain unresolved. Central to this point is the neural system that in snails consists of several ganglia that regulate the animals' physiology and behaviour patterns. The availability of a genomic resource for the freshwater snail Biomphalaria glabrata provides a mean towards the high throughput analysis of changes in the central nervous system (CNS) following infection with Schistosoma miracidia.

Whole genome analysis of a schistosomiasis-transmitting freshwater snail.

Biomphalaria snails are instrumental in transmission of the human blood fluke Schistosoma mansoni. With the World Health Organization's goal to eliminate schistosomiasis as a global health problem by 2025, there is now renewed emphasis on snail control. Here, we characterize the genome of Biomphalaria glabrata, a lophotrochozoan protostome, and provide timely and important information on snail biology.

Steroid Androgen Exposure during Development Has No Effect on Reproductive Physiology of Biomphalaria glabrata.

Gastropod mollusks have been proposed as alternative models for male reproductive toxicity testing, due to similarities in their reproductive anatomy compared to mammals, together with evidence that endocrine disrupting chemicals can cause effects in some mollusks analogous to those seen in mammals. To test this hypothesis, we used the freshwater pulmonate snail, Biomphalaria glabrata, for which various genetic tools and a draft genome have recently become available, to investigate the effects of two steroid androgens on the development of mollusk secondary sexual organs. Here we present the results of exposures to two potent androgens, the vertebrate steroid; 5α-dihydrotestosterone (DHT) and the pharmaceutical anabolic steroid; 17α-methyltestosterone (MT), under continuous flow-through conditions throughout embryonic development and up to sexual maturity.

The nuclear receptors of Biomphalaria glabrata and Lottia gigantea: implications for developing new model organisms.

Nuclear receptors (NRs) are transcription regulators involved in an array of diverse physiological functions including key roles in endocrine and metabolic function. The aim of this study was to identify nuclear receptors in the fully sequenced genome of the gastropod snail, Biomphalaria glabrata, intermediate host for Schistosoma mansoni and compare these to known vertebrate NRs, with a view to assessing the snail's potential as a invertebrate model organism for endocrine function, both as a prospective new test organism and to elucidate the fundamental genetic and mechanistic causes of disease. For comparative purposes, the genome of a second gastropod, the owl limpet, Lottia gigantea was also investigated for nuclear receptors.
