Development of a Personal Ultrasound Exposimeter for Occupational Health Monitoring.

Prolonged exposure to airborne ultrasound in a workplace can have a detrimental influence on a worker's well-being. Given the ever-increasing use of ultrasonic industrial equipment, it is of vital importance-and may also be regulated by law-to monitor ultrasound exposure during a normal workday as part of workplace risk assessment. However, the devices currently utilized exhibit limitations with regard to both their operational frequency and their portability (wearability).

Role of pro-inflammatory cytokines of pancreatic islets and prospects of elaboration of new methods for the diabetes treatment.

Several relations between cytokines and pathogenesis of diabetes are reviewed. In type 1 and type 2 diabetes an increased synthesis is observed and as well as the release of pro-inflammatory cytokines, which cause the damage of pancreatic islet cells and, in type 2 diabetes, the development of the insulin resistance. That process results in the disturbed balance between pro-inflammatory and protective cytokines.

Relationship between the induction of inflammatory processes and infectious diseases in patients with ischemic stroke.

Pro-inflammatory cytokines participate in the induction of ischemic stroke. So far, their participation in the cerebral ischemia was proven for the tumor necrosis factor TNF-α, interleukin-1 (IL-1), and interleukin-6 (IL-6). The release of the pro-inflammatory cytokines into the extracellular space causes the enlargement of the brain damage region, and consequently increases the neurological deficit and negatively affects the survival rate prognoses.
