#1
Nabil Fanous, Shadi Zari
Importance: Despite their great potential, medium and deep trichloroacetic acid peels are underused in light-skinned patients and are rarely used in darker-skinned patients because of the widespread fear of pigmentary complications and scarring. This concern has led many physicians to opt for the use of lighter types of peels (glycolic acid peel, Jessner peel, etc) and different lasers and intense light technologies. Trichloroacetic acid peels have been described in numerous publications...

Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

The proportion of men receiving non-surgical cosmetic procedures has risen substantially in recent years. Various physiologic, anatomic, and motivational considerations differentiate the treatments for male and female patients. Nevertheless, research regarding approaches to the male cosmetic patient is scarce. We sought to provide an overview and sex-specific discussion of the most popular cosmetic dermatologic procedures pursued by men by conducting a comprehensive literature review pertaining to non-surgical cosmetic procedures in male patients...

Citrus limonoids are secondary metabolites and exhibit a variety of biological activities. In this study, we elucidated the suppression of adipogenesis by a Citrus limonoid kihadanin B and determined its molecular mechanism in mouse 3T3-L1 adipocytes. Kihadanin B was purified from the peels of immature Citrus unshiu by HPLC, and its chemical structure was determined by NMR and mass spectrometry. Kihadanin B reduced the lipid accumulation with the reduction of the expression levels of the adipogenic and lipogenic genes, but did not affect lipolysis in adipocytes...

We developed a novel strategy for fabricating poly(3,4-ethylenedioxythiophene) (PEDOT) patterns on various substrates, including hydrogels, via sequential solution procedure without multistep chemical etching or lift-off processes. First, PEDOT nanothin films were prepared on a glass substrate by solution phase monomer casting and oxidative polymerization. As a second step, after UV-induced poly(ethylene glycol) (PEG) photolithography at the PEDOT/PEG interface through a photomask, the hydrogel was peeled away from the PEDOT-coated glass substrate to detach the UV-exposed PEDOT region, which left the UV nonexposed PEDOT region intact on the glass substrate, resulting in PEDOT patterns...

Insect residue adhesion to moving surfaces such as turbine blades and aircraft not only causes surface contamination problems but also increases drag on these surfaces. Insect fouling during takeoff, climb and landing can result in increased drag and fuel consumption for aircraft with laminar-flow surfaces. Hence, certain topographical and chemical features of non-wettable surfaces need to be designed properly for preventing insect residue accumulation on surfaces. In this work, we developed a superhydrophobic coating that is able to maintain negligible levels of insect residue after 100 high speed (50 m/s) insect impact events produced in a wind tunnel...

The application of pectinases in industrial olive-oil processes is restricted by its production cost. Consequently, new fungal strains able to produce higher pectinase titers are required. The aim of this work was to study the capability of Aspergillus giganteus NRRL10 to produce pectinolytic enzymes by SSF and evaluate the application of these in olive-oil extraction. A. giganteus was selected among 12 strains on the basis of high pectinolytic activity and stability. A mixture composed by wheat bran, orange, and lemon peels was selected as the best substrate for enzyme production...

Potato peels consist of a tissue called phellem, which is formed by suberized cell layers. The degradation of suberin, a lipidic and recalcitrant polymer, is an ecological process attributed to soil fungal populations; however, previous studies have suggested that Streptomyces scabiei, the causal agent of potato common scab, possesses the ability to degrade suberin. In the present study, S. scabiei was grown in medium containing suberin-enriched potato phellem as the sole carbon source and its secretome was analyzed periodically (10- to 60-d-old cultures) with a special focus on proteins potentially involved in cell wall degradation...
