Treatment of the Induration of the Soft Tissue of the Lower Eyelids After Accidental Oil Injections.

Injection cosmetic procedures have shown rapid continuing growth in the last 2 decades. Various substances are injected into the periorbital region for skin quality increase and correction of tear trough deformity, including hyaluronic acid, peptides, collagen, and others. Sometimes patients get accidentally injected with different substances that are not approved for cosmetic treatment in this anatomic area.

Mechanistic Insights of Ethylene Polymerization on Phillips Chromium Catalysts.

Silica-supported chromium oxide catalysts, also named Phillips chromium catalysts (PCCs), provide more than half of the world's production of high- and medium-density polyethylenes. PCCs are usually prepared in the Cr(VI)/SiO form, which is subjected to reductive activation. It has been explicitly proven that CO reduces Cr(VI) to Cr(II) species that initiate ethylene polymerization; ethylene activates Cr(VI) sites as well, but the nature of the catalytic species is complicated by the presence of the ethylene oxidation products.

Predicting Structural Susceptibility of Proteins to Proteolytic Processing.

The importance of 3D protein structure in proteolytic processing is well known. However, despite the plethora of existing methods for predicting proteolytic sites, only a few of them utilize the structural features of potential substrates as predictors. Moreover, to our knowledge, there is currently no method available for predicting the structural susceptibility of protein regions to proteolysis.

[Masculinizing mastectomy with nipple-areola graft autotransplantation for female-to-male transsexualism].

Objective: To develop the method of masculinizing mammoplasty with nipple grafting female-to-male transsexuals with BMI >30 kg/m, large breast volume and severe ptosis.

Material And Methods: There were 114 mastectomies in 57 patients with nipple grafting technique. The methods of areola grafting and scar design were modified to improve aesthetic results.

Achieving a Good Aesthetic Result in the Correction of Giant Nevus of the Labiomental Area.

Benign skin lesions of the face require appropriate surgical treatment. Giant pigmented skin lesions possess the high risk of malignancy which sometimes is not possible to diagnose preoperatively. Majority of the traditional techniques for lower lip and chin reconstruction were developed for the skin cancer resections and are extensively aggressive and disfiguring in case of benign lesions.
