Otolaryngol Clin North Am 2022 Jun 21. Epub 2022 Jun 21.

Private Practice; Department of Otolaryngology-Head and Neck Surgery, University of Texas Medical Branch, Galveston, TX, USA. Electronic address:

The perioral area can be an important feature to convey femininity, particularly when speaking and smiling. A feminine lip has a shorter distance between the nasal sill and the vermillion border, fullness of the vermillion, and a few millimeters of tooth show with the mouth slightly open. The keys to a good outcome are incision design that respects the natural anatomy, placing the tension of the lift deep to the dermis to take tension off of the skin incision, determining the appropriate amount of lift for the patient's anatomy, and not violating the orbicularis oris.

Trans-Encapsidation of Foot-and-Mouth Disease Virus Genomes Facilitates Escape from Neutralizing Antibodies.

Viruses 2022 May 27;14(6). Epub 2022 May 27.

The Pirbright Institute, Ash Road, Woking GU24 0NF, UK.

Foot-and-mouth disease is an economically devastating disease of livestock caused by foot-and-mouth disease virus (FMDV). Vaccination is the most effective control measure in place to limit the spread of the disease; however, the success of vaccination campaigns is hampered by the antigenic diversity of FMDV and the rapid rate at which new strains emerge that escape pre-existing immunity. FMDV has seven distinct serotypes, and within each serotype are multiple strains that often induce little cross-protective immunity. Read More

Lower Inspiratory Breathing Depth Enhances Pulmonary Delivery Efficiency of ProAir Sprays.

Pharmaceuticals (Basel) 2022 Jun 3;15(6). Epub 2022 Jun 3.

Department of Biomedical Engineering, University of Massachusetts, Lowell, MA 01854, USA.

Effective pulmonary drug delivery using a metered-dose inhaler (MDI) requires a match between the MDI sprays, the patient's breathing, and respiratory physiology. Different inhalers generate aerosols with distinct aerosol sizes and speeds, which require specific breathing coordination to achieve optimized delivery efficiency. Inability to perform the instructed breathing maneuver is one of the frequently reported issues during MDI applications; however, their effects on MDI dosimetry are unclear. Read More
