A Randomized Controlled Trial With Female Teachers: Are there Differences Between and Within the Outcomes in Voice Therapy Groups With and Without Carryover Strategies?

Purpose: We investigated if outcomes differ between voice therapy groups systematically using carryover strategies (attempts to generalize new vocal skills outside the clinic) and voice therapy with no emphasis on any generalizing process (here referred to as traditional voice therapy).

Method: A randomized controlled trial was conducted. Participants (53 female teachers with voice disorders) were randomly allocated into three groups: Carryover (a group receiving voice therapy using carryover strategies), Trad (a group receiving voice therapy with no emphasis on any generalizing process), Controls (a group on an eight-week non-therapy period).

Alginate/Gelatin scaffolds incorporated with Silibinin-loaded Chitosan nanoparticles for bone formation in vitro.

Silibinin is a plant derived flavonolignan known for its multiple biological properties, but its role in the promotion of bone formation has not yet been well studied. Moreover, the delivery of Silibinin is hindered by its complex hydrophobic nature, which limits its bioavailability. Hence, in this study, we fabricated a drug delivery system using chitosan nanoparticles loaded with Silibinin at different concentrations (20μM, 50μM, and 100μM).

Role of Computed Tomography in Pediatric Chest Conditions.

CT is the preferred cross-sectional imaging modality for detailed evaluation of anatomy and pathology of the lung and tracheobronchial tree, and plays a complimentary role in the evaluation of certain chest wall, mediastinal, and cardiac abnormalities. The article provides an overview of indications and different types of CT chest, findings in common clinical conditions, and briefly touches upon the role of each team member in optimizing and thus reducing radiation dose.
