    Organic Solvent as Internal Standards for Quantitative and High-Throughput Liquid Interfacial SERS Analysis in Complex Media.
    Anal Chem 2018 Apr 3;90(8):5232-5238. Epub 2018 Apr 3.
    College of Food Science and Engineering , Hefei University of Technology , Hefei , Anhui 230009 , China.
    Liquid-state interfacial nanoparticle arrays for surface-enhanced Raman scattering (SERS) promises a practical, substrate-free, and rapid analysis but faces a great challenge to develop a batch and uniform fabrication strategy with stable internal standards (IS) because of the difficulties in precisely locating both the IS tags and analytes in the same local structure under the harsh conditions of biphasic liquid interface. Here, we develop a fast batch preparation of self-ordered dense Au nanoparticle (GNP) arrays on cyclohexane/water biphasic interface in 96-well plates with the assist of acetone as the phase-crossing inducer. The acetone can extract the pesticide molecules via a simple dipping sample peels and can rapidly capture and locate the pesticide molecule into the plasmonic hotspots. Read More

    Advanced Functional Thin Films Department , Korea Institute of Materials Science (KIMS) , Changwon , Gyeongnam 51508 , Republic of Korea.
    A surface-enhanced Raman scattering (SERS) sensor comprising silver nanowires (AgNWs) and genetically engineered M13 bacteriophages expressing a tryptophan-histidine-tryptophan (WHW) peptide sequence (BPWHW) was fabricated by simple mixing of BPWHW and AgNW solutions, followed by vacuum filtration onto a glass-fiber filter paper (GFFP) membrane. The AgNWs stacked on the GFFP formed a high density of SERS-active hot spots at the points of nanowire intersections, and the surface-coated BPWHW functioned as a bioreceptor for selective pesticide detection. The BPWHW-functionalized AgNW (BPWHW/AgNW) sensor was characterized by scanning electron microscopy, confocal scanning fluorescence microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy.

    Background: Chemical peels are a mainstay of aesthetic medicine and an increasingly popular cosmetic procedure performed in men.

    Objective: To review the indications for chemical peels with an emphasis on performing this procedure in male patients.

    Materials And Methods: Review of the English PubMed/MEDLINE literature and specialty texts in cosmetic dermatology, oculoplastic, and facial aesthetic surgery regarding sex-specific use of chemical peels in men. Read More

    The disposal of agricultural wastes such as fresh banana peels (BPs) is an environmental issue. In this work, fresh BPs were successfully transformed into nitrogen-doped carbon nanoparticles (N-CNPs) by using a high shear mixer facilitated crushing method (HSM-FCM) followed by carbonization under Ar atmosphere. Ammonia-activated N-CNPs (N-CNPs-NH₃) were prepared via subsequent ammonia activation treatments at a high temperature. Read More

    Chemical peels are an alternative and/or a complementary treatment to the surgical procedures for skin aging. The purpose of this article is to specify the procedures and the indications of the three principal types of chemical peels: alpha-hydroxy acids, trichloracetic acid, phenol-croton oil peel. The clinical examination will determine the depth of the lesions to treat and will take into consideration counter-indications and specific limits to each patient. Read More

    Citrus sinensis and Citrus limon peels were used to synthesize two different kinds of carbon quantum dots (CQDs) via an unsophisticated and inexpensive carbonization procedure. The proposed synthesis is straightforward and adheres to the principles of green chemistry since no organic solvents are used and no toxic by-products are formed, while the residual resources employed facilitate the large scale synthesis of dots. The Citrus sinensis and Citrus limon peels are proved to be excellent precursors for the synthesis of CQDs with highly practical applications. Read More

    Production and Optimization of Physicochemical Parameters of Cellulase Using Untreated Orange Waste by Newly Isolated Emericella variecolor NS3.

    Cellulase enzymes have versatile industrial applications. This study was directed towards the isolation, production, and characterization of cellulase enzyme system. Among the five isolated fungal cultures, Emericella variecolor NS3 showed maximum cellulase production using untreated orange peel waste as substrate using solid-state fermentation (SSF). Read More

    Histological case-control study of peeling-induced skin changes by different peeling agents in surgically subcutaneous undermined skin flaps in facelift patients.

    A histological evaluation of peeling-induced skin changes in subcutaneous undermined preauricular facial skin flaps of nine patients was performed. There were three treatment groups: Trichloroacetic acid (TCA) 25%, TCA 40% and phenol/croton oil; one group served as control. Two independent evaluators determined the epidermal and dermal thickness and the depth of necrosis (micrometre). Read More

    Melasma: an Up-to-Date Comprehensive Review.

    Melasma is a common acquired condition of symmetric hyperpigmentation, typically occurring on the face, with higher prevalence in females and darker skin types. Multiple etiologies, including light exposure, hormonal influences, and family history, have been implicated in the pathogenesis of this disorder. Overall prevalence ranges widely at 1-50%, since values are typically calculated within a specific ethnic population within a geographic region. Read More

    Production of ligninolytic enzymes and some diffusible antifungal compounds by white-rot fungi using potato solid wastes as the sole nutrient source.

    Aims: The aim of this study was to evaluate the synthesis of ligninolytic enzymes and some diffusible antifungal compounds by white-rot fungi (WRF) using peels or discarded potato as the sole nutrient source.

    Methods And Results: The strain Trametes hirsuta Ru-513 highlighted for its laccase activity (595 ± 33 U l ), which is able to decolourize 87% of an anthraquinone dye using potato peels as the sole nutritional support. A native polyacrylamide gel of laccase proteins showed the presence of two isoenzymes, corresponding to proteins of 56 and 67 kDa, which were detected by SDS-PAGE. Read More
