BACKGROUND Saliva samples are easily collectable and non-invasive, and the monitoring of natural steroidal hormones, such as estrone (E1), 17β-estradiol (E2), estriol (E3), progesterone (P), and testosterone (T), in saliva has attracted much attention due to its numerous potential clinical and health-related applications. Because E1, E2, E3, P and T are useful indicators in numerous clinical an...

There are no studies evaluating the possible use of immunoglobulin A1 (IgA1) as an early marker for peri-implant inflammation. The aim of this study was to evaluate the IgA1 levels in peri-implant sulcular fluid (PISF) and saliva of partially edentulous patients as an indicator of mucositis. Twenty-seven patients were examined to determine the peri-implant status based on probing depth and blee...

Saliva provides a useful and noninvasive alternative to blood for many biomedical diagnostic assays. The level of the hormone cortisol in blood and saliva is related to the level of stress. We present here the development of a portable surface plasmon resonance (SPR) biosensor system for detection of cortisol in saliva. Cortisol-specific monoclonal antibodies were used to develop a competition ...

Several human mucosal fluids are known to possess an innate ability to inhibit human immunodeficiency virus type 1 (HIV-1) infection and replication in vitro. This study compared the HIV-1 inhibitory activities of several mucosal fluids, whole, submandibular/sublingual (sm/sl), and parotid saliva, breast milk, colostrum, seminal plasma, and cervicovaginal secretions, from HIV-1-seronegative don...

OBJECTIVE Dental caries is one of the most common infectious diseases worldwide. Saliva has many functions in the oral cavity and is the first line defense against dental caries. Oxidative stress can affect initiation and progression of many inflammatory and infectious diseases such as dental caries. Thus the aim of this study was to evaluate the relationship between total antioxidant capacity ...

The use of a 10-day observation to determine whether a dog is rabid is standard practice. This study was conducted in order to look for evidence of rabies vius in saliva and cerebrospinal fluid (CSF) of suspected live rabid dogs at the time of quarantine by using a SYBR Green real-time RT-PCR based assay for the detection of rabies virus RNA. Saliva and CSF of dogs were collected once on the da...

To evaluate precision we used one sample from a smoker and one sample indicating passiveinhalation. The calculated within-assay CV of 10 replicates(80-L volumes)was 4.5% at 5.2 g’L and 1.4% at 220 g/L. The reagents and assay standards proved stable over a 3-month period. However, as with commercially prepared reagents, recalibration was desirable every week or so. Although the antiserum was pre...

A 25-basepair deletion variant of MYBPC3 occurs at high frequency in individuals of South Asian descent and is estimated to affect 55 million people worldwide, carrying an increased likelihood of cardiomyopathy. Since this variant is prevalent and severe in this subpopulation, quick and affordable screening to provide risk-assessment to guide treatment for these patients is critical. An RNaseH ...
