Nutritional bile acidity supplements unveils health benefits about digestive tract healthy reputation involving dialect sole (Cynoglossus semiliaevis).
Oxidative stress generated by cigarette smoking, environmental pollution, or other noxious particles leads to epigenetic changes in the cells of the respiratory tract. They reflect cell adaptation in response to chronic exposure to external factors. Although there is no change in the genetic code, epigenetic changes may be heritable and translated from one generation to another, accumulating abnormalities and rendering cells into entirely different phenotype, causing disease. DNA methylation, post-translation histone modification, ubiquitination, sumoylation and miRNA transcriptional regulation are the major processes that are responsible for the epigenetic control of gene expression. All of them are reversible. They can be regulated by targeting specific enzymes/proteins involved in the process in order to mitigate inflammation. Chronic respiratory diseases have epigenetic signatures that affect gene expression in the lung. Targeting them provides the development of novel diagnostic and therapeutic approaches in respiratory medicine. Nutrigenomics reveals the beneficial effect of natural phytochemicals, affecting key steps in the signaling pathways of chronic respiratory diseases.

A broncho-pleural fistula is often detected. Despite various therapeutic options developed over the last five decades it remains a major surgical challenge. MATERIALS AND METHODS A literature search in MEDLINE database was carried out (accessed through PubMed), by using a combination of the following key-words and MeSH terms pneumonectomy, postoperative, complications, broncho-pleural fistula, empyema, prevention. The following areas of intervention were identified epidemiology, etiology, prevention. RESULTS Pleural empyema in a post-pneumonectomy cavity occurs in up to 16% of patients with a mortality of more than 10%. It is associated with broncho-pleural fistula in up to 80% of them, usually in the early postoperative months. Operative mortality could reach 50% in case of broncho-pleural fistula. THZ816 Unfavourable prognostic factors are benign disease, COPD, right-sided surgery, neoadjuvant and adjuvant therapy, time of chest tube removal, long bronchial stump and mechanical ventilation. Bronchial stump protection with vascularised flaps is of utmost importance in the prevention of complications. CONCLUSION Postpneumonectomy pleural empyema is a common complication with high mortality. The existing evidence confirms the role of bronchopleural fistula prevention in the prevention of life-threatening complications.

One of the main goals in the treatment is aesthetic improvement of the affected teeth. Two clinical cases of patients with white spot fluorosis lesions on frontal teeth are presented. All treated teeth are infiltrated with low-viscous light-curing resin (ICON, DMG). A significant improvement in the aesthetic appearance of all the treated tooth surfaces is visible immediately after resin infiltration, and in most of the teeth - a complete disappearance of the white spots. Resin infiltration is an alternative micro-invasive approach for treatment of white spot lesions of different origin. It allows a quick and natural recovery of the affected teeth.

MATERIALS AND METHODS This study is a double-blind clinical trial. Ninety-nine patients were included in the study. They were undergoing forearm and hand surgery and were referred to Vali-e-Asr Hospital in Arak. The patients were divided into three groups. The first group received lidocaine (1.5%) and dexmedetomidine (0.5 μg/kg). The second group patients were given lidocaine (1.5%) plus magnesium. In the control group, lidocaine (1.5%) was adjusted to 35 cc with normal saline. The final volume was 35 cc in the three groups. Sensory and motor block and pain were measured and data were analyzed using SPSS v. 20. The final volume was 35 cc in the three groups. RESULTS The sensory and motor block onset time and the stabilization time of the sensory and motor block in the magnesium sulfate group were lower (p less then 0/001). Pain in recovery, 2, 4, 6, 12, and 24 hours after surgery was lower in the magnesium sulfate group when compared with the dexmedetomidine group (p less then 0.001). The lowest dose of opioid was used in the dexmedetomidine group 24 hours after surgery (p less then 0.001). CONCLUSION The results showed that dexmedetomidine decreases pain. Magnesium sulfate increased the sensory and motor block onset time, and the sensory and motor block stabilization time, but dexmedetomidine increases the motor block duration.

Most of the factors affecting the prognosis have been analyzed on a wide group of traumatic brain injuries. Nonetheless, there are few studies analyzing factors influencing the prognosis regarding patients with EDH and SDH. The aim of the study is to identify factors which have prognostic value in relation to 6-month outcome of patients undergoing surgery for acute hematoma. PATIENTS AND METHODS The study included a group of 128 patients with isolated craniocerebral injuries. The patients were divided into two groups, namely a group of 28 patients operated on due to epidural hematoma and a group of 100 patients operated on due to acute subdural hematoma. All patients were operated and treated in the Department of Neurosurgery at the Medical University in Lublin from 1.10.2014 to 31.08.2017. The following factors from the groups were analyzed demographic data, physiological factors, laboratory factors, computed tomography scan characteristics, and time between the trauma and the surgery.
