Mechanical force promotes tissue and molecular changes in adipose tissue regeneration post-transplantation.

Introduction: Fat grafting often yields inconsistent and suboptimal results, necessitating improved fat processing techniques. A stromal vascular fraction (SVF) gel created using mechanical emulsification demonstrates superior retention rates to conventional Coleman fat grafts.

Methods: This study investigated the mechanisms at play by transplanting fat aspirates from liposuction patients-either processed as Coleman fat grafts or further refined into an SVF gel via mechanical shear force-onto the backs of nude mice.

Dermatoscope for the diagnosis of erythema with purpura induced by lidocaine/prilocaine cream: A case report.

Background: Lidocaine/prilocaine (EMLA) cream is a local anesthetic that is applied to the skin or mucosa during painful therapeutic procedures with few reported side effects.

Case Summary: Here, we report the use of dermatoscopy to identify a case of erythema with purpura, a rare side effect, after the application of 5% EMLA cream.

Conclusion: We conclude that erythema with purpura is caused by irritation and toxicity associated with EMLA, but the specific mechanism by which the toxic substance affects skin blood vessels is unclear.

Congenital arhinia: A rare case.

Patient: Male, 4 months

Final Diagnosis: Congenital arhynia Symptoms: Absence of the nose Medication: - Clinical Procedure: - Specialty: Pediatrics and Noenatology • Genetics.

Objective: Congenital defects.

Background: Congenital nasal absence (arhinia) is an extremely rare malformation.

[Construction of a tissue engineering skin with epidermal stem cells].

Objective: To constitute a composite skin substitute that can proliferate well with epidermal stem cells and fibroblasts on collagen sponge.

Methods: Epidermal stem cells were selected by rapid attachment to collagen IV for 10-15 min and cultured on 3T3 feeder layers. Collagen was extracted from rat tail.
