Abstract
Background Cowden’s syndrome is a genetic disorder characterized by multiple oral hamartomas and an increased risk of internal malignancy. These mucocutaneous lesions can be physically disfiguring and psychologically distressing. As a result, patients frequently seek treatment for their destruction. Removal of oral hamartomas is often a challenge due to their sensitive location and high risk of recurrence. Objective To review the clinical use, effectiveness, and safety of a fractional ablative laser to treat multiple oral hamartomas in a patient with Cowden’s syndrome. Materials and Methods A thorough literature review pertaining to treatment of oral hamartomas and a discussion of an illustrative case showcasing successful lesional destruction with a fractional ablative carbon dioxide (CO2) laser in a 33-year-old man with Cowden’s syndrome. Results Multiple oral hamartomas were effectively removed with fractional CO2 laser vaporization. No infection, scarring, dermatitis, nor lesional recurrence were observed 6 months post-treatment. Conclusion Fractional CO2 laser vaporization can be used effectively to treat multiple oral hamartomas associated with Cowden’s syndrome.

Zinc oxide nanoparticles synthesized from Aspergillus terreus induces oxidative stress-mediated apoptosis through modulating apoptotic proteins in human cervical cancer HeLa cells. J Pharm Pharmacol 2021; 73:221-232. [PMID: 33793807 DOI: 10.1093/jpp/rgaa043] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 11/24/2020] [Indexed: 11/13/2022]
Abstract
OBJECTIVES This study was aimed to analyze the cytotoxicity of biogenic zinc oxide nanoparticles (ZnO NPs) in human cervical epithelial cancer HeLa. METHODS The ZnO NPs was synthesized from the culture filtrated of Aspergillus terreus, and examined by UV-spectroscopy, X-ray diffraction (XRD), transmission electron microscope (TEM), energy-dispersive X-ray (EDX) and Fourier transform infrared (FTIR) analysis. The cytotoxicity of synthesized ZnO NPs was analyzed by the MTT assay, and the expression of apoptotic proteins was examined by Western blot analyses. KEY FINDINGS The ZnO NPs exhibited concentration-dependent cytotoxicity on HeLa cells and induced the apoptosis as evidenced by reduced superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) levels, and increased reactive oxygen species (ROS) and diminished mitochondrial membrane potential (MMP) was noticed in ZnO NPs treated HeLa cells. Western blot analyses explored that the Bcl-2 expression was significantly downregulated, whereas, the expression of p53, Bax, Caspase-3, Caspase-9 and Cytochrome-c were significantly upregulated in ZnO NPs treated cells. CONCLUSION Consequently, the mycosynthesized ZnO NPs induces apoptosis in HeLa cells by persuading oxidative damage and modulating the apoptotic proteins. Therefore, A. terreus synthesized ZnO NPs could be used as an effective chemotherapeutic agent for cervical cancer treatment.

Abstract
We studied the features of the appearance of broadband "white" emission in CaF2-x mol% ErF3 and ZrO2-x mol% Er2O3 (x = 0-25) nanosized dielectric particles upon their excitation by intense laser radiation with λ exc = 1550 nm. Comparison of the results of this study with the results obtained previously for other materials doped with Er3+ ions confirmed the thermal nature of the observed emission and made it possible to identify the main factors affecting its occurrence. These include the band gap of the material and the presence of defects in its structure. A method of applying the effect in dermatology is proposed.

Abstract
Metallic nanoparticles were extensively examined to explore their impending exploitations over pharmaceutical purposes. Current work attempting to explores the cytotoxic capacity of zinc oxide (ZnO) nanoparticles besides to human melanoma cell line (A375). Viability of cells was resoluted, and the promising cytotoxicity potential was exhibited by zinc oxide nanoparticles. Cellular adhesion and morphology was determined by propidium iodide assay. Characterization studies like UV-Spectroscopy, X-ray diffraction (XRD) investigation, transmission electron microscope (TEM), energy dispersive X-ray (EDX) Spec, and Fourier transform infrared (FT-IR) examination confirms the accessibility of measurement, form and volume. The mRNA expression of apoptotic genes like caspase 3, 8 and 9 was elevated followed by the exposure to ZnO nanoparticles and it was narrowly proved that ZnO nanoparticles stimulates the apoptotic cell necrosis at the transcriptional stage. Cardiospermum halicacabum down regulated the apoptotic gene expressions. Reactive oxygen species (ROS) accumulation was augmented at concentration reliant mode, that changed normalize numerous indicator pathways and manipulate the kinetic cellular actions. ZnO nanoparticle synthesized Cardiospermum halicacabum might persuades programmed cell necrosis via elevated ROS levels in cells. CH-ZnONPs was further stimulates the markers of apoptosis and aggravates necrosis of cancerous cells, toxicity to cells, and accretion of ROS. With sourced on above whole data, this might accomplished that CH-ZnONPs amalgamated Cardiospermum halicacabum appreciably possessed a toxicity to human melanoma cells (A375) via provoking the apoptotic cell necrosis, entailed feasible efficacy of CH-ZnONPs besides malignancy management.

Abstract
The main aim of the study was to identify and describe methods using non-ionizing radiation (NIR) such as electromagnetic fields (EMF) and optical radiation in Swedish health care. By examining anticipated exposure levels and by identifying possible health hazards we also aimed to recognize knowledge gaps in the field. NIR is mainly used in health care for diagnosis and therapy. Three applications were identified where acute effects cannot be ruled out: magnetic resonance imaging (MRI), transcranial magnetic stimulation (TMS) and electrosurgery. When using optical radiation, such as class 3 and 4 lasers for therapy or surgical procedures and ultra-violet light for therapy, acute effects such as unintentional burns, photo reactions, erythema and effects on the eyes need to be avoided. There is a need for more knowledge regarding long-term effects of MRI as well as on the combination of different NIR exposures. Based on literature and after consulting staff we conclude that the health care professionals' knowledge about the risks and safety measures should be improved and that there is a need for clear, evidence-based information from reliable sources, and it should be obvious to the user which source to address.

Abstract
Melanoma is a most aggressive skin cancer with limited therapeutic options and its incidence is increasing rapidly in recent years. The discovery and application of new targeted therapy agents have shown significant benefits. However, adverse side-effects and resistance to chemotherapy remain formidable challenges in the clinical treatment of malignant melanoma. Nanotherapeutics offers an important prospect of overcoming these drawbacks. The anti-tumoral applications of nanomedicine are varied, including those in chemotherapy, RNA interference, photothermal therapy, and photodynamic therapy. Furthermore, nanomedicine allows delivery of the effector structures into the tumor site via passive or active targeting, thereby allowing increased therapeutic specificity and reduced side effects. In this review, we summarize the latest developments in the application of nanocarrier-mediated targeted drug delivery to melanoma and nanomedicine-related clinical trials in melanoma treatment. We also discuss existing problems and opportunities for future developments, providing direction and new thoughts for further studies.
