Fluorescent Gold Nanoprobes for the Sensitive and Selective Detection for Hg2+

A simple, cost-effective yet rapid and sensitive sensor for on-site and real-time Hg2+ detection based on bovine serum albumin functionalized fluorescent gold nanoparticles as novel and environmentally friendly fluorescent probes was developed. Using this probe, aqueous Hg2+ can be detected at 0.1 nM in a facile way based on fluorescence quenching. This probe was also applied to determine the Hg2+ in the lake samples, and the results demonstrate low interference and high sensitivity

Christ siemens touraine syndrome: A rare case report

Christ-Siemens-Touraine (CST) is a rare hereditary disorder of X-linked recessive trait, characterized by abnormal development of two or more structures or tissues of ectodermal origin. The common clinical findings include hypodontia, hypohydrosis, hypotrichosis, and onychodysplasia. Although hypodontia is common, anodontia is a rare feature. Most of the patients are suffering from social rejection and consequent psychological trauma because of the facial dysmorphism and absence of multiple teeth. Oral rehabilitation is of prime importance for such patients. This article presents a case in a 5½-year-old boy presenting with altered manifestations affecting almost all the ectodermal structures like skin, hair, nails, teeth, sebaceous glands, sweat glands, salivary glands, mammary glands, and tear glands. He also had complete anodontia and dry mouth. A multidisciplinary treatment was given to the patient with the collaboration of various health professionals. The child gained confidence and was relieved from the psychological impact following the prosthetic rehabilitation

A clinicoradiographic comparison of the effects of platelet-rich fibrin gel and platelet-rich fibrin membrane as scaffolds in the apexification treatment of young permanent teeth

Aims: This triple blinded clinical trial was undertaken to check whether Platelet rich firin in its membrane form is as reliable as when it is in the gel form. Settings and Design: Triple blinded randomized clinical trial. Methods and Material: 20 patients in PRF gel group and 20 patients in PRF membrane group selected after randomization and considering inclusion and exclusion criteria were taken up for this study. The samples were clinically and radiographically evaluated for success. Results and Conclusions: Regenerative endodontics with PRF membrane is easier and less time consuming. They have similar clinical success.PRF gel gave a better radiographic success in 12 months period

Nasoalveolar molding treatment in presurgical infant orthopedics in cleft lip and cleft palate patients

The nasoalveolar molding (NAM) technique is a new approach to presurgical infant orthopedics that reduces the severity of the initial cleft alveolar and nasal deformity. This technique facilitates the primary surgical repair of the nose and lip to heal under minimal tension, thereby reducing scar formation and improving the esthetic result. NAM technique is the nonsurgical, passive method of bringing the gum and lip together by redirecting the forces of natural growth. NAM has proved to be an effective adjunctive therapy for reducing hard and soft tissue cleft deformity before surgery. This paper reviews the basic principles of NAM therapy, various types of appliances used in this therapy, protocol followed, and a critical evaluation of the advantages and disadvantages of this technique. Universally authors have agreed the positive outcome of NAM for better esthetics after cleft lip and palate (CLP) repair, but the long-term effects of this therapy are yet to be substantiated. Despite a relative paucity of high-level evidence, NAM appears to be a promising technique that deserves further research
