Curcumin-loaded scaffolds in bone regeneration.

In recent years, there has been a notable surge in the development of engineered bone scaffolds intended for the repair of bone defects. While autografts and allografts have traditionally served as the primary methods in bone tissue engineering, their inherent limitations have spurred the exploration of novel avenues in biomedical implant development. The emergence of bone scaffolds not only facilitates bone reconstruction but also offers a platform for the targeted delivery of therapeutic agents.

The wound healing effect of polycaprolactone-chitosan scaffold coated with a gel containing Zataria multiflora Boiss. volatile oil nanoemulsions.

Aims: Thymus plant is a very useful herbal medicine with various properties such as anti-inflammatory and antibacterial. Therefore, the properties of this plant have made this drug a suitable candidate for wound healing. In this study, hydroxypropyl methylcellulose (HPMC) gel containing Zataria multiflora volatile oil nanoemulsion (neZM) along with polycaprolactone/chitosan (PCL-CS) nanofibrous scaffold was used, and the effect of three experimental groups on the wound healing process was evaluated.

Fabrication of alginate-based hydrogel microparticle via ruthenium-catalyzed photocrosslinking.

In this study, we developed an alginate-based microparticle production process via sodium ruthenium(II) tris-bipyridyl dication (Ru)/ammonium persulfate (SPS)-mediated visible light crosslinking system using a microfluidic device. Microparticles were prepared by crosslinking phenolic-substituted alginate (AlgPh) and incorporated gelatin (GelPh) in an aqueous solution containing SPS, which flowed into an ambient immiscible liquid paraffin-containing Ru using coaxial double orifice microfluidic device. The hydrogel microparticles appeared with the desired geometries and dimensions under optimal conditions.

Effect of PCL nanofiber mats coated with chitosan microcapsules containing cinnamon essential oil for wound healing.

Introduction: Cinnamon is one of the most common spices that has been studied for its anti-inflammatory, antioxidant, and antibacterial properties in wound healing. The purpose of this study was to evaluate the effectiveness of polycaprolactone nanofiber mats coated with chitosan microcapsules loaded with cinnamon essential oil in wound healing.

Material And Methods: For this purpose, chitosan microcapsules containing cinnamon essential oil (µCS-CiZ) were prepared by ion gelation and PCL nanofibers by electrospinning.

Comparison of aural rehabilitation outcomes in presence and absence of back ground noise in hearing impaired children with and without attention deficit hyperactivity disorder (ADHD).

Objective: We sought to understand the extend of improvement in seven major skills to determine the best rehabilitation approach in hearing impaired young children with and without attention deficit and hyperactivity disorder (ADHD).

Methods: Newsha developmental scale was assessed in 40 hearing impaired children with and without ADHD in two conditions, in which seven major skills (hearing, speech, receptive language, expressive language, cognition, social communication, and motor skills) were evaluated. Two separate analyses were conducted, each after six months of rehabilitation.

Preparing a persian version of kimberley indigenous cognitive assessment for assessing the cognitive problems of illiterate geriatric patients.

Background: The rate of dementia is increasing rapidly. With the recognized high rate of illiteracy among geriatric patients, preparing an appropriate device for special screening among the low-educated elderly seems to be necessary. The aim of this study is to prepare and assess the psychometric properties of the Persian version of the Kimberley Indigenous Cognitive Assessment (KICA) in Iranian adults, in 2012.

Efficacy of memoral herbal on prevention of electroconvulsive therapy-induced memory impairment in mood disorder patients (isfahan - iran 2011).

Background: Electroconvulsive therapy (ECT) is one of the most efficacious treatment for major depressive disorder (MDD), it is also used as a rapid and efficacious treatment for other psychiatric disorders, especially treatment resistant ones. The cognitive impairment is one of the most important side effects of ECT. This study examined the Memoral herbal efficacy in prevention of ECT-induced memory impairment.
