Role of tranexamic acid in nasal surgery: A systemic review and meta-analysis of randomized control trial.

Objective: Nasal surgeries (such as Functional Endoscopic Sinus Surgery, Rhinoplasty, and Septorhinoplasty) are popular procedures. But perioperative bleeding, eyelid edema, and periorbital ecchymosis remain problems. Tranexamic acid (TXA) is an antifibrinolytic, and it was used to reduce the perioperative bleeding.

Chemical Peeling with a Modified Phenol Formula for the Treatment of Facial Freckles on Asian Skin.

Background: Chemical peeling is an efficient method for the treatment of pigment disorders. For freckles, medium-depth to deep peeling using a phenol solution is one of the most effective chemical peels, and modifications of facial skin can be observed up to 20 years after peeling. However, applying phenol to the skin may cause serious side effects.

Hypoxic preconditioning up-regulates DJ-1 protein expression in rat heart-derived H9c2 cells through the activation of extracellular-regulated kinase 1/2 pathway.

Myocardial preconditioning is a powerful phenomenon that can attenuate ischemia/reperfusion-induced oxidant stress and elicit delayed cardioprotection. Its mechanisms involve activation of intracellular signaling pathways and up-regulation of the protective antioxidant proteins. DJ-1 protein, as a multifunctional intracellular protein, plays an important role in attenuating oxidant stress and promoting cell survival.
