The past 20 years have seen the glutamatergic hypothesis go from theory to phase III trials of novel mechanism antipsychotics. We review the recent literature on glutamatergic theory, covering assessment and genetic studies, as well as drug development in animals and humans. Although evidence continues to accumulate in support of ...

ABSTRACT Asthma is an inflammatory airway disease, and oxidative stress was proven to be involved in its pathogenesis. Apocynin effectively inhibits the main source of reactive oxygen species (ROS)-nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-by blocking its activation. The aim of this study was to investigate the effect of inhaled apocynin ...

ABSTRACT Streptococcus pneumoniae is an important causative agent of pneumonia in humans. Pulmonary epithelial surfaces constitutes not only a mechanical barrier against invading pathogens but also essentially contribute to innate immunity by producing antimicrobial peptides such as human β-defensin-2 (hBD-2) and -3 (hBD-3). In this study the authors demonstrated that ...

Implant therapy offers a wide range of possibilities in prosthetics. Especially for completely edentulous patients with early tooth loss due to periodontitis, implant therapy is an option to regain a comfortable, esthetic dental rehabilitation. Several studies have indicated that osseointegrated implants can be placed successfully in periodontally compromised patients but ...
