Hyaluronan (hyaluronic acid) and its regulation in human saliva by hyaluronidase and its inhibitors.
The presence of hyaluronan (HA), hyaluronidase and hyaluronidase inhibitors has been assayed in pure resting and stimulated parotid saliva and also in resting and stimulated mixed saliva utilizing an ELISA-type assay and its modifications. Results confirmed the presence of hyaluronan in all saliva specimens which generally decreased upon stimulation. Hyaluronan in parotid saliva was of high mol...
In recent years, there have been increasing numbers of infectious disease outbreaks that spread rapidly to population centers resulting from global travel, population vulnerabilities, environmental factors, and ecological disasters such as floods and earthquakes. Some examples of the recent outbreaks are the Ebola epidemic in West Africa, Middle East respiratory syndrome coronavirus (MERS-Co) i...
S difficulties in clinical studies of endocrine function based on plasma sampling regimens include time-consuming venipuncture and measurement of the "total" rather than the "free" biologically active fraction in plasma. Simple methods for determining plasma free steroids have not yet been developed, and most current procedures involve technically demanding ultrafiltration or equilibrium dialys...
Data on possible involvement of ovarian function by means of decreased progesterone production and/or imbalance in progesterone/estrogen ratio iir the pathogenesis of benign breast disease have been reported in the literature (5). More recently, attention has been given to the possible role ofprolactin on altered breast physiology (7); the influences exerted by this peptide on ovarian stiroid h...
BACKGROUND Human saliva, a complex secretion that contains a mixture of inorganic and organic molecules, plays an essential role in the maintenance of oral health. Mucins are the major macromolecular component of the secretion and are considered the first line of defense for epithelial tissues. The aim of this study was to compare levels of mucins (MUC5B, MUC7, and MUC1) in saliva of young subj...
OBJECTIVES We compared salivary flow, serum and saliva testosterone, and femur bone mineral density (BMD) of menopausal women with or without xerostomia. STUDY DESIGN A case/control study was performed on 60 selected menopausal women with or without xerostomia. BMD and testosterone concentration were measured by a dual-energy x-ray absorptiometry system and enzyme-linked immunosorbent assay m...
BACKGROUND Concentrations of estrogen and progesterone within the breast could provide a better reflection of breast cancer risk than levels in the circulation. We developed highly sensitive immunoassays for multiple steroid hormones and proteins in the nipple aspirate fluid (NAF), which can be obtained noninvasively with a simple suction device. Previous studies showed that NAF hormone levels ...
Background and Aims: Among Human Immunodeficiency Virus (HIV)-infected individuals, Epstein-Barr virus (EBV) and Human Herpesvirus (HHV)-8 could cause significant illness as opportunistic infections. The purpose of the present study was to evaluate the prevalence of EBV and HHV-8 in saliva specimens obtained from HIV-1 infected Iranian individuals under the Highly Active Antiviral Therapy (HAAR...
Antibody (IgG) responses to the saliva of Phlebotomus argentipes were investigated using serum samples from regions of India endemic and non-endemic for visceral leishmaniasis (VL). By pre-adsorbing the sera against the saliva of the competing human-biting but non-VL vector P. papatasi, we significantly improved the specificity of a P. argentipes saliva enzyme-linked immunosorbent assay. Using ...
