AIMS To assess the validity of reaction to severe stress and adjustment disorder diagnoses registered in the Danish Psychiatric Central Research Register (DPCRR), to examine the documentation of stressful and traumatic events in the medical records, and to investigate the occurrence of stress diagnoses among persons not registered in the DPCRR. METHODS Among 101,633 patients diagnosed with In...

BACKGROUND lower-limb stress fracture is one of the most common types of running injuries. There have been several studies focusing on the association between stress fractures and biomechanical factors. In the current study, the ground reaction force and loading rate are examined. There is disagreement in the literature about whether the history of stress fractures is associated with ground rea...

cancer treatment is still of the greatest challenges that health care providers and patients are facing. one of the unsolved problems in cancer treatment is cells’ reaction to metabolic stress caused by harsh nutritional conditions around tumor. in order to be able to treat this disease properly, it is important to understand the true nature of the disease. in fact, the cells inside the central...

the biological mechanisms of tooth movement are based on the response of periodontal tissues to mechanical forces. the final result of these responses is remodeling of the extracellular matrix. tissue reactions may vary depending upon the type, magnitude and duration of the applied forces. the purpose of the present study was to analyze the effects of centrifugal force on the transcription of c...

the first reaction between food components and biological tissues occurs in the oral cavity. saliva modulates the ecosystem in the oral cavity and plays a critical role in oral homeostasis. in addition, saliva is a first line of defense against free radical-mediated stress. salivary antioxidant defense mechanisms seem to be very important. in this study we discuss in detail free radicals (fr) a...

BACKGROUND Results of studies that address the influence of stress on salivary flow rate and composition are controversial. The aim of this study was to reveal the influence of stress vulnerability and different phases of stress reactivity on the unstimulated and stimulated salivary flow rate. We examined that acute mental stress does not change the salivary flow rate. In addition, we also exam...
