BACKGROUND: Oral squamous cell carcinoma (OSCC) is one of the most dangerous cancers in the body, producing serious complications with individual behaviors. Many different pathogenetic factors are involved in the carcinogenesis of OSCC. Cancer cells derived from oral keratinocytes can produce different carcinogenic signaling pathways through differences in protein expression, but their protein expression profiles cannot be easily explored with ordinary detection methods. METHODS: The present study compared the protein expression profiles between two different types of OSCCs, which were analyzed through immunoprecipitation high-performance liquid chromatography (IP-HPLC)...

Smell and odours play a vital role in social interaction. Halitosis is a social problem that affects one-third of the population causing a negative impact in the quality of life. There is little knowledge on the prevalence and management of halitosis in Multiple Sclerosis (MS) patients. The present study aimed to evaluate the presence of halitosis in patients with MS when compared to a control group and the treatment with antimicrobial photodynamic therapy (aPDT) against halitosis. This is a case-control clinical study where 60 patients were evaluated: 30 MS patients in treatment at the Specialties Clinic School of Medicine, and 30 healthy patients, matched in age and gender, for the control group...

Halitosis or bad breath is a problem that affects many people and its source is generally found in the oral cavity (intra-oral halitosis). Bacteria in the oral cavity produce volatile sulphur compounds such as hydrogen sulphide and methyl mercaptan that not only emit an unpleasant odour, but may also have toxic effects on the periodontal tissues. Good oral hygiene, a healthy periodontium and healthy teeth are the basis for the prevention of intra-oral halitosis and dentists and dental hygienists therefore play an essential role in its prevention...

BACKGROUND: Revision endoscopic sinus surgery (RESS) may be required for partially controlled or uncontrolled chronic rhinosinusitis. Studies that reported technical success, e.g., sinus ostia patency after RESS, do not address whether the patient's symptoms and quality of life (QOL) improve after surgery. However, patient-reported outcome measures (PROM) are useful to assess the impact of sinus surgery on a patient's symptoms and QOL. OBJECTIVE: This systematic review was undertaken to evaluate the impact of RESS on PROMs...

Lana Ahmed Shinawi
BACKGROUND: The application of computer-aided design computer-aided manufacturing (CAD CAM) technology in the fabrication of complete dentures, offers numerous advantages as it provides optimum fit and eliminates polymerization shrinkage of the acrylic base. Additionally, the porosity and surface roughness of CAD CAM resins is less compared to conventionally processed resins which leads to a decrease in the adhesion of bacteria on the denture base, which is associated with many conditions including halitosis and aspiration pneumonia in elderly denture wearers...

Room-temperature (RT) operation sensors are constantly in increasing demand because of their low power consumption, simple operation, and long lifetime. However, critical challenges such as low sensing performance, vulnerability under highly humid state, and poor recyclability hinder their commercialization. In this work, sub-10 nm hollow, bimetallic Pt-Ag nanoparticles (NPs) were successfully formed by galvanic replacement reaction in bioinspired hollow protein templates and sensitized on the multidimensional SnO2-WO3 heterojunction nanofibers (HNFs)...

To develop a new generation of diagnostics for halitosis, replacing the subjective organoleptic assessment, a series of exhaled breath analyzers has been developed and assessed. All three devices rely on the assessment of exhaled volatile sulfuric compounds (VSCs), which are mainly generated in and emitted from the oral cavity, contributing to the malodor. Portable, on-site and easy to use, these devices have potential for non-invasive diagnosis of halitosis. However, global assessment of exhaled VSCs alone has two main drawbacks: (i) the absence of VSCs does not rule out halitosis; (ii) non-sulfuric volatile compounds that could be biomarkers of systemic diseases, found in up to 15% of halitosis cases, are neglected...

Tea is produced from the Camellia sinensis plant and can generally be divided into categories based on how they are processed. In general, green tea that is unfermented C. sinensis has been considered superior to black tea in health benefits. It contains a unique set of catechins that possess biological activity as antioxidant, anti-inflammatory and antiproliferative, which is potentially significant to the prevention and treatment of various forms of diseases. Oral cavity oxidative stress and inflammation, consequent cigarettes due to nicotine and acrolein, may be reduced in the presence of green tea polyphenols...
