Evaluation effect of alginate hydrogel containing losartan on wound healing and gene expression.

Skin tissue engineering has become an increasingly popular alternative to conventional treatments for skin injuries. Hydrogels, owing to their advantages have become the ideal option for wound dressing, and they are extensively employed in a mixture of different drugs to accelerate wound healing. Sodium alginate is a readily available natural polymer with advantages such as bio-compatibility and a non-toxicological nature that is commonly used in hydrogel form for medical applications such as wound repair and drug delivery in skin regenerative medicine.

Development of carboxymethyl cellulose/gelatin hydrogel loaded with Omega-3 for skin regeneration.

Hydrogels have several characteristics, including biocompatibility, physical similarity with the skin's extracellular matrix, and regeneration capacity. Cell migration and proliferation are facilitated by natural polymers such as gelatin (Gel) and carboxymethyl cellulose (CMC). Gelatin dressing acts as a structural framework for cell migration into the wound area, stimulating cell division and promoting granulation tissue formation.

Effects of Tumor Microenvironment on the Primo Vascular Pattern in the Mouse Model of Metastatic Breast Cancer.

Background: : Tumor survival, promotion, and metastatic functions are regulated by the tumor microenvironment (TME). The primo vascular system (PVS), the third circulatory system in animals, is currently thought to be a highly effective pathway for the spread of cancer cells.

Objectives: : In the present study, we intend to determine the TME effects on the PVS pattern in breast cancer for the first time.

Nanofibrous polycaprolactone/gelatin scaffold containing gold nanoparticles: Physicochemical and biological characterization for wound healing.

In this study, gold nanoparticles were loaded into poly (ε-caprolactone) (PCL)/gelatin nanofibrous matrices to fabricate a potential wound dressing. The mats were produced by electrospinning of PCL/gelatin solution supplemented with synthesized gold nanoparticles (200, 400 and 800 ppm). Prepared scaffolds were investigated regarding their chemical properties, morphology, mechanical properties, surface wettability, water-uptake capacity, water vapor permeability, porosity, blood compatibility, microbial penetration test and cellular response.

A novel hydrogel containing 4-methylcatechol for skin regeneration: in vitro and in vivo study.

Skin damages are usual physical injuries and different studies have been done to improve wound healing. Hydrogel due to its properties like a moist environment and cooling wound site is a good option for wound treatment. In this study, we evaluated the consequence of using alginate/chitosan hydrogel contained various dosages of 4-Methylcatechol (0, 0.

Hydrogel nanocomposite based on alginate/zeolite for burn wound healing: and study.

Objectives: The main objective of the current assay was to evaluate the antibacterial and regenerative effects of hydrogel nanocomposite containing pure natural zeolite (clinoptilolite) integrated with alginate (Alg) as wound healing/dressing biomaterials.

Materials And Methods: The zeolites were size excluded, characterized by SEM, DLS, XRD, FTIR, and XRF, and then integrated into Alg hydrogel followed by calcium chloride crosslinking. The Alg and alginate zeolite (Alg/Zeo) hydrogel was characterized by swelling and weight loss tests, also the antibacterial, hemocompatibility, and cell viability tests were performed.

Improving sciatic nerve regeneration by using alginate/chitosan hydrogel containing berberine.

Peripheral nerve injuries are the common results of trauma that lead to pain and handicap in patients. Berberine due to its properties like antibiotic, immunostimulant, antitumor, antimotility, and positive effect on neurological disorders can be used to enhance peripheral nerve injuries. In this study, alginate/chitosan hydrogel containing different concentrations of berberine (0, 0.
