The process of being granted asylum is complex, often taking months and years. Asylum seekers face high risk of being denied asylum in the United States. As medical and psychological evaluations assist in achieving successful asylum outcomes, human rights asylum clinics are being established throughout the country to facilitate these types of evaluations.

Community-based participatory research (CBPR) is an approach that engages community residents with a goal of influencing change in community health systems, programs, or policies. As such, CBPR is particularly relevant to historically marginalized communities that often have not directly benefited from the knowledge research produces. This article analyzes a youth empowerment program, Chicago's Youth Health Service Corps, from a CBPR perspective.

This cross-section study was designed to assess the effect of topical application of melatonin to the gingiva on salivary RANKL, osteoprotegrin (OPG) and melatonin levels as well as plasma melatonin in 30 patients with diabetes and periodontal disease and in a control group of 30 healthy subjects. Salivary RANKL and OPG were measured by enzyme-linked immunosorbent assay and salivary and plasma melatonin by radioimmunoassay using commercial kits. Periodontograms were performed using the Florida Probe(®).

Purpose: The aim of this study was to evaluate the effect of the topical application of melatonin on osteointegration of dental implants in Beagle dogs 5 and 8 weeks after their insertion.

Materials And Methods: For subsequent insertion of dental implants, upper and lower premolars and molars were extracted from 12 Beagle dogs. Each mandible received cylindrical screw implants of 3.

Background: The antioxidant and anti-inflammatory hormone melatonin is secreted by saliva into the oral cavity, where it may protect the mucosal and gingival tissues from radical damage. To date, no studies have addressed the potential beneficial role of melatonin in the acute inflammatory response that follows oral surgical interventions, especially tooth extractions. The aim of this study was to determine whether tooth extraction induces changes in plasma oxidative stress levels, and whether melatonin treatment may counteract these changes.

Background: Oxidative stress constitutes the basis for many diseases and it may account for the severity of systemic and oral disease complications. The aim of this study was to assess whether saliva may be used to detect the body's oxidative stress level.

Methods: Oxidative stress was determined in saliva from 14 diabetic patients and 10 heroin addicts; two different pathologic conditions related to free radical damage, and 21 healthy control subjects were included in the study.

Among other functions, melatonin exerts both antioxidative and immunoregulatory roles. The indoleamine is secreted in the saliva, although its role into the mouth is not known. Diabetic patients frequently display oral cavity pathologies such as periodontal disease (PD), an inflammatory disease coursing with an increase in free radical production.
