Local administration of ReveromycinA ointment suppressed alveolar bone loss in mice.

J Pharmacol Sci 2021 Sep 27;147(1):40-47. Epub 2021 May 27.

Department of Orthodontics, School of Dentistry, Aichi Gakuin University, 2-11 Suemori-Dori, Chikusa-ku, Nagoya 464-8651, Aichi, Japan. Electronic address:

ReveromycinA (RMA) was developed and is a unique agent for inhibiting osteoclast activity. In a previous study, we experimentally induced periodontal disease in a high-turnover osteoporosis osteoprotegerin-knockout mice (OPG KO) model and found that intraperitoneal administration of RMA inhibited alveolar bone resorption. We prepared a novel RMA-containing ointment for topical non-invasive administration in the oral cavity, in preparation for possible future clinical application. Read More

Exploiting dentine matrix proteins in cell-free approaches for periradicular tissue engineering.

Tissue Eng Part B Rev 2021 Jul 26. Epub 2021 Jul 26.

University of Birmingham College of Medical and Dental Sciences, 150183, School of Dentistry, Institute of Clinical Sciences, 5 Mill Pool Way, Edgbaston, Birmingham, Birmingham, Birmingham, United Kingdom of Great Britain and Northern Ireland, B5 7EG.

The recent discovery of mesenchymal stem cells within periapical lesions (PL-MSC) has presented novel opportunities for managing periradicular diseases in adult teeth by way of enhancing tissue regeneration. This discovery coincides with the current paradigm shift towards biologically driven treatment strategies in endodontics, which have typically been reserved for non-vital immature permanent teeth. One such approach that shows promise is utilising local endogenous non-collagenous dentine extracellular matrix components (dECM) to recruit and upregulate the intrinsic regenerative capacity of PL-MSCs in situ.

Department of Immunology and Molecular Microbiology, Texas Tech University Health Sciences Center, Lubbock, Texas, USA.

Topical antimicrobials that reduce the bacterial bioburden within a chronically-infected wound may have helpful or harmful effects on the healing process. We used murine models of full-thickness skin wounds to determine the effects of the novel biofilm-dispersing wound gel (BDWG) and its gel base on the healing of uninfected wounds. The rate of wound closure over 19 days was comparable among the BDWG-treated (BT) wounds and the controls. Read More

High-Resolution Quantitative Mapping of Macaque Cervicovaginal Epithelial Thickness: Implications for Mucosal Vaccine Delivery.

Front Immunol 2021 28;12:660524. Epub 2021 Jun 28.

Southwest National Primate Research Center, San Antonio, TX, United States.

Vaginal mucosal surfaces naturally offer some protection against sexually transmitted infections (STIs) including Human Immunodeficiency Virus-1, however topical preventative medications or vaccine designed to boost local immune responses can further enhance this protection. We previously developed a novel mucosal vaccine strategy using viral vectors integrated into mouse dermal epithelium to induce virus-specific humoral and cellular immune responses at the site of exposure. Since vaccine integration occurs at the site of cell replication (basal layer 100-400 micrometers below the surface), temporal epithelial thinning during vaccine application, confirmed with high resolution imaging, is desirable.

A Novel Device-Integrated Drug Delivery System for Local Inhibition of Urinary Tract Infection.

Front Microbiol 2021 25;12:685698. Epub 2021 Jun 25.

Research Unit of Clinical Microbiology, University of Southern Denmark and Odense University Hospital, Odense, Denmark.

Catheter-associated urinary tract infection (CAUTI) is a frequent community-acquired infection and the most common nosocomial infection. Here, we developed a novel antimicrobial catheter concept that utilizes a silicone-based interpenetrating polymer network (IPN) as balloon material to facilitate a topical slow-release prophylaxis of antibacterial agents across the balloon to the urinary bladder. The balloon material was achieved by modifying low shore hardness silicone tubes with a hydrogel interpenetrating polymer in supercritical CO using the sequential method. Read More

Clascoterone: a new topical anti-androgen for acne management.

Int J Dermatol 2021 Jul 9. Epub 2021 Jul 9.

Department of Dermatology, Malabar Medical College Hospital and Research Centre, Kozhikode, India.

Clascoterone is an androgen receptor inhibitor which has been approved by the United States Food and Drug Administration for the topical treatment of acne vulgaris in patients 12 years of age and older. It competes with androgens, especially dihydrotestosterone, for androgen-receptor binding and limits their binding, thus inhibiting downstream signaling of pathways involved in the pathogenesis of acne. It inhibits androgen receptor-regulated gene transcription, and antagonizes lipid and inflammatory cytokine production in a dose-dependent manner in human primary sebocytes. Read More

Mahidol University Faculty of Medicine Siriraj Hospital, 65106, Pharmacology, Faculty of Medicine Siriraj Hospital, 2 Prannok, Bangkoknoi, Bangkok, Thailand, 10700;

Oxidative stress and mitochondrial dysfunction play a role in the process of skin photoaging via activation of matrix metalloproteases (MMPs) and the subsequent degradation of collagen. The activation of nuclear factor E2-related factor 2 (Nrf2), a transcription factor controlling antioxidant and cytoprotective defense systems, might offer a pharmacological approach to prevent skin photoaging. We therefore investigated might offer a pharmacological approach to prevent skin photoaging. Read More

Topical Sevoflurane: A Novel Treatment for Chronic Pain Caused by Venous Stasis Ulcers.

Anesth Pain Med 2021 Feb 24;11(1):e112832. Epub 2021 Feb 24.

LSU Health Shreveport, Department of Anesthesiology, Shreveport, LA, USA.

In the US, an estimated 1 - 2% of chronic venous insufficiency (CVI) patients (of 6 - 7 million nationwide) develop at least one venous stasis ulcer (VSU) during their illness. Of these, approximately 40% develop subsequent ulcers, making VSU prognostically poor. Current management of VSU is costly, with poor prognosis, high recurrence rate, inadequate pain management, and significantly reduced quality of life (QoL). Read More
