Cellulose and Lignin-Derived Scaffold and Their Biological Application in Tissue Engineering, Drug Delivery, and Wound Healing: A Review.

The goal of tissue engineering is to repair and regenerate diseased and damaged tissues and organs with functional and biocompatible materials that mimic native and original tissues which leads to maintaining and improvement of tissue function. Lignin and cellulose are the most abundant polymers in nature and have many applications in industry. Moreover, recently the physicochemical behaviors of lignin and cellulose, including biocompatibility, biodegradability, and mechanical properties, have been used in diverse biological applications ranging from drug delivery to tissue engineering.

The Study of Serum Level of Interleukin-2, Interleukin-6, and Tumor Necrosis Factor-alpha in Stable and Progressive Vitiligo Patients from Sina Hospital in Tabriz, Iran.

Background: Vitiligo is an acquired depigmenting disorder characterized by the loss of functional melanocytes from the epidermis. Although the etiology of vitiligo is unknown, over the last few years, substantial data from clinical research have greatly supported the "Autoimmune theory." Vitiligo has two major forms: progressive and stable.

Skin Burns: Review of Molecular Mechanisms and Therapeutic Approaches.

Burn wounds are one of the main causes of skin damage. Based on World Health Organization statistics, almost 300 000 people worldwide die of burns each year. In severe burns, the cells and blood vessels are often injured and the blood supply to the wound is disturbed.

Adipose tissue-derived stem cells upon decellularized ovine small intestine submucosa for tissue regeneration: An optimization and comparison method.

The extracellular matrix of different mammalian tissues is commonly used as scaffolds in the field of tissue engineering. One of these tissues, which has frequently been studied due to its structural and biological features, is the small intestine submucosal membrane. These research are mainly done on the porcine small intestine.

Comparative Study of Dermatoscopic and Histopathologic Results in Facial Basal Cell Carcinoma and Melanocytic Nevi.

Background: Dermatoscopy can be applied to diagnose pigmented skin lesions. The aim of the present study was to compare dermatoscopic and histopathologic results in basal cell carcinoma (BCC) and melanocytic nevus of theface.

Materials And Methods: In an analytical-descriptive study, 61 patients suspected of BCC or melanocytic nevi of face were randomly selected.

Comparative study of intralesional steroid injection and cryotherapy in alopecia areata.

Background And Objectives: Alopecia areata (AA) is a common, non-scarring type of hair loss, affecting approximately 2.1% of the population, many modality of treatment recommended like steroid injection, topical Immunotherapy and several systemic therapies. The aim of this study was to compare intralesional steroid injection and cryotherapyoutcomes in AA.

The efficacy of permethrin 5% vs. oral ivermectin for the treatment of scabies.

Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The aim of this study is to compare the efficacy and safety of permethrin 5% lotion with oral ivermectin for the treatment of scabies.
