Caregiver Experiences With Oral Bilingualism in Children Who Are Deaf and Hard of Hearing in the United States: Impact on Child Language Proficiency.

Purpose: Best practices recommend promoting the use of the home language and allowing caregivers to choose the language(s) that they want to use with their child who is deaf or hard of hearing (DHH). We examined whether Spanish-speaking caregivers of children who are DHH receive professional recommendations on oral bilingualism that follow best practices. We also assessed whether professional recommendations, caregiver beliefs, and language practices had an impact on child language(s) proficiency.

Transmembrane stem cell factor protein therapeutics enhance revascularization in ischemia without mast cell activation.

Stem cell factor (SCF) is a cytokine that regulates hematopoiesis and other biological processes. While clinical treatments using SCF would be highly beneficial, these have been limited by toxicity related to mast cell activation. Transmembrane SCF (tmSCF) has differential activity from soluble SCF and has not been explored as a therapeutic agent.

Applications of decellularized extracellular matrix in bone and cartilage tissue engineering.

Regenerative therapies for bone and cartilage injuries are currently unable to replicate the complex microenvironment of native tissue. There are many tissue engineering approaches attempting to address this issue through the use of synthetic materials. Although synthetic materials can be modified to simulate the mechanical and biochemical properties of the cell microenvironment, they do not mimic in full the multitude of interactions that take place within tissue.

Syndesome Therapeutics for Enhancing Diabetic Wound Healing.

Chronic wounds represent a major healthcare and economic problem worldwide. Advanced wound dressings that incorporate bioactive compounds have great potential for improving outcomes in patients with chronic wounds but significant challenges in designing treatments that are effective in long-standing, nonhealing wounds. Here, an optimized wound healing gel was developed that delivers syndecan-4 proteoliposomes ("syndesomes") with fibroblast growth factor-2 (FGF-2) to enhance diabetic wound healing.

Syndecan-4 enhances PDGF-BB activity in diabetic wound healing.

Unlabelled: Non-healing ulcers are a common consequence of long-term diabetes and severe peripheral vascular disease. These non-healing wounds are a major source of morbidity in patients with diabetes and place a heavy financial burden on the healthcare system. Growth factor therapies are an attractive strategy for enhancing wound closure in non-healing wounds but have only achieved mixed results in clinical trials.

Syndecan-4 Enhances Therapeutic Angiogenesis after Hind Limb Ischemia in Mice with Type 2 Diabetes.

Delivering syndecan-4 with FGF-2 improves the effectiveness of FGF-2 therapy for ischemia in the diabetic disease state. The syndecan-4 proteoliposomes significantly enhance in vitro tubule formation as well as blood perfusion and vessel density in the ischemic hind limbs of diseased ob/ob mice. Syndecan-4 therapy also induces a marked immunomodulation in the tissues, increasing the polarization of macrophages toward the M2 phenotype.
