The implant-retained fixed partial denture, or bridge, is a highly efficient restorative modality. The primary challenge with this restoration, however, lies in achieving the optimal design of the pontic, which needs to be esthetic, comfortable, and easily cleansable by the patient, a factor that can directly enhance prosthesis longevity. An ovate design is desirable for the pontic area.

Inferior alveolar nerve (IAN) damage following implant placement is a severe complication that can compromise a patient's quality of life. Previous studies have suggested that a safety zone of 2 mm, if maintained, might avoid this problem. This retrospective study evaluates implants placed in closer proximity to the IAN without resulting in any postoperative neurologic complications and suggests a new concept of safety distance.

Zinc plays a key role in the modulation of neuronal redox homeostasis. A decreased zinc availability is associated with neuronal NADPH oxidase and nitric oxide synthase activation, deregulation of redox signaling, and impaired glutathione synthesis. The present work tested the hypothesis that zinc is necessary in the neuronal defense response against dopamine (DA)-induced oxidative stress, in particular through heme oxygenase-1 (HO-1) upregulation.

When performing Breast Conserving Surgery (BCS) with Intraoperative Radiation Therapy (IORT), positive resection margin necessitates not only re-lumpectomy-but also the addition of fractionated whole breast radiation. This retrospective study of 106 patients undergoing BCS and IORT aims to evaluate intraoperative margin assessment use in our center, and the contribution of the MarginProbe device (MP) to achieving negative surgical margins. Eleven out of 106 lumpectomy specimens had a total of 17 margins positive for tumor cells.

Background: Mathematical models suggest that 570,000 HIV infections could be averted between 2011 and 2025 in Zimbabwe if the country reaches 80% voluntary medical male circumcision (VMMC) coverage among 15- to 49-year-old male subjects. Yet national coverage remains well below this target, and there is a need to evaluate interventions to increase the uptake.

Methods: A cluster-randomized trial was conducted to assess the effectiveness of Make-The-Cut-Plus (MTC+), a single, 60-minute, sport-based intervention to increase VMMC uptake targeting secondary school boys (14-20 years).

Rationale: Although cancer is a main cause of human morbidity worldwide, relatively small numbers of new cancer cases are recorded annually in single urban areas. This makes the association between cancer morbidity and environmental risk factors, such as ambient air pollution, difficult to detect using traditional methods of analysis based on age standardized rates and zonal estimates.

Study Goal: The present study investigates the association between air pollution and cancer morbidity in the Greater Haifa Metropolitan Area in Israel by comparing two analytical techniques: the traditional zonal approach and more recently developed Double Kernel Density (DKD) tools.
