Division of Endodontics and Orthodontics, Herman Ostrow School of Dentistry of USC, University of Southern California, Los Angeles, California. Electronic address:

Introduction: Hypertension is a common major systemic disease and 1 of the most significant causes of mortality worldwide. Persistent hypertension is 1 of the risk factors for stroke, heart attack, heart failure, and arterial aneurysm and is a leading cause of chronic kidney failure. Common medications used to treat hypertension include beta blockers, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and calcium channel blockers.

The human oral phageome.

Periodontol 2000

June 2021

Department of Prosthetic Dentistry and Biomedical Materials Science, Hannover Medical School, Hannover, Germany.

Oral bacteriophages (or phages), especially periodontal ones, constitute a growing area of interest, but research on oral phages is still in its infancy. Phages are bacterial viruses that may persist as intracellular parasitic deoxyribonucleic acid (DNA) or use bacterial metabolism to replicate and cause bacterial lysis. The microbiomes of saliva, oral mucosa, and dental plaque contain active phage virions, bacterial lysogens (ie, carrying dormant prophages), and bacterial strains containing short fragments of phage DNA.

Trigeminal neuralgia (TN) involves chronic neuropathic pain, characterized by attacks of repeating short episodes of unilateral shock-like pain, which are abrupt in onset and termination. Anticonvulsants, such as carbamazepine, are the gold standard first-line drugs for pharmacological treatment. Microvascular decompression (MVD) surgery is often the course of action if pharmacological management with anticonvulsants is unsuccessful.

This systematic review focused on the efficacy of topical products in reducing temporomandibular joint disorder (TMD)-associated pain, in comparison to placebo or control interventions. The EMBASE, Web of Science, Cochrane Library, and MEDLINE via PubMed databases were searched for randomized controlled trials (RCTs) using topical interventions in adults diagnosed with TMD. The pain intensity was the primary outcome, and other clinical findings were the secondary outcomes.

State Key Laboratory of Developmental Biology of Freshwater Fish, College of Life Science, Hunan Normal University, Changsha 410081, PR China; Section of Infection and Immunity, Herman Ostrow School of Dentistry of USC, Los Angeles 90089, USA.

Ferritin H can participate in the regulation of teleostean immunity. ORF sequences of RCC/WCC/WR-ferritin H were 609 bp, while WR-ferritin H gene possessed chimeric fragments or offspring-specific mutations. In order to elucidate regulation of immune-related signal transduction, three fibroblast-like cell lines derived from caudal fin of red crucian carp (RCC), white crucian carp (WCC) and their hybrid offspring (WR) were characterized and designated as RCCFCs, WCCFCs and WRFCs.

Objective: To compare transoral robotic surgery (TORS) versus non-TORS tongue resection procedures performed for obstructive sleep apnea from January 2010 to September 2015 using a national database, focusing on patient characteristics, performance of concurrent procedures, operative time, length of hospital stay, and postoperative complications.

Methods: A cohort of adults undergoing TORS and non-TORS tongue resection procedures was identified in the Nationwide Inpatient Sample, a publicly-available national administrative database incorporating a stratified sample of hospital discharge records. Outcomes were annual case volumes, prolonged (≥3 days) hospital stay, and complications.

Background: Ameloblasts are epithelially derived cells responsible for enamel formation through a process known as amelogenesis. Amongst the several transcription factors that are expressed during amelogenesis, both and transcription factors play important role. and mouse mutants, exhibit similar amelogenesis defects, namely enamel hypoplasia, while humans with amelogenesis imperfecta (AI) carry mutations in the human homologues of MSX2 or SP6 genes.

Objective: To describe CHAMP (Children's Oral Health Promotion Program) evaluating the impact of two motivational methods in increasing dental care access.

Methods: CHAMP is a multi-dimensional oral health promotion programme that recruited and screened underprivileged children/families from community sites in Los Angeles County between 2012 and 2018. A randomized clinical trial (RCT) enrolled children/families into one or more motivational interventions (intra-oral camera and/or social work consultation) designed to impact subsequent scheduling of dental appointments.

Role of stem cell therapies in treating chronic wounds: A systematic review.

World J Stem Cells

July 2020

Division of Plastic and Reconstructive Surgery, Keck School of Medicine of USC, Los Angeles, CA 90033, United States.

Background: The impairment of cutaneous wound healing results in chronic, non-healing wounds that are caused by altered wound environment oxygenation, tissue injury, and permissive microbial growth. Current modalities for the treatment of these wounds inadequately address the complex changes involved in chronic wound pathogenesis. Consequently, stem cell therapies have emerged as a potential therapeutic modality to promote cutaneous regeneration through trophic and paracrine activity.

Mitigation of peri-implantitis by rational design of bifunctional peptides with antimicrobial properties.

ACS Biomater Sci Eng

May 2020

Herman Ostrow School of Dentistry of USC, Center for Craniofacial Molecular Biology, University of Southern California, Los Angeles, USA.

The integration of molecular and cell biology with materials science has led to strategies to improve the interface between dental implants with the surrounding soft and hard tissues in order to replace missing teeth and restore mastication. More than 3 million implants have been placed in the US alone and this number is rising by 500,000/year. Peri-implantitis, an inflammatory response to oral pathogens growing on the implant surface threatens to reduce service life leading to eventual implant failure, and such an outcome will have adverse impact on public health and create significant health care costs.

Division of Plastic and Reconstructive Surgery, Keck School of Medicine of USC, 1510 San Pablo St. Suite 415, Los Angeles, CA, 90033, USA.

Head and neck lymphedema (HNL) is a disfiguring disease affecting over 90% of patients treated for head and neck cancer. Animal models of lymphedema are used to test pharmacologic and microsurgical therapies; however, no animal model for HNL is described in the literature to date. In this study we describe the first reproducible rat model for HNL.
