Protection and Active Decontamination of Dairy Cattle Heifers against Lipophilic Toxins (PCBs) from Diet.

We studied the effects of a hydrophobized reversed-phase feed adsorbent in the form of a polyoctylated polysilicate hydrogel (POPSH) on productivity indicators, metabolic adaptation, and on the level of polychlorinated biphenyls (PCBs) in the blood of growing Holsteinized black-and-white heifers during the transition period. Two groups of two-month-old heifers of 20 head each were used. The experimental group received POPSH in addition to the main diet.

Total full-thickness skin grafting for treating patients with extensive facial burn injury: A 10-year experience.

Introduction: Facial burns are not only a severe burn injury, but result in psychological disturbance. The improvement of the methods of treating facial burns remains topical. The aim of the study was to evaluate the effectiveness of approach based on full-thickness skin autografting for facial burn injuries.

Hydrophobized Reversed-Phase Adsorbent for Protection of Dairy Cattle against Lipophilic Toxins from Diet. Efficiensy in Vitro and in Vivo.

The steady growth of inflammatory diseases of the udder in dairy cattle forces us to look for the causes of this phenomenon in the context of growing chemical pollution of the environment and feeds. Within the framework of this concept, an analysis was made of the polarity level of the three toxic impurity groups, which are commonly present in dairy cattle feeds. These impurities are presented by mycotoxins, polyaromatic hydrocarbons (PAH) and persistent organic pollutants (POP).

Orthotopic transplantation of a tissue engineered diaphragm in rats.

The currently available surgical options to repair the diaphragm are associated with significant risks of defect recurrence, lack of growth potential and restored functionality. A tissue engineered diaphragm has the potential to improve surgical outcomes for patients with congenital or acquired disorders. Here we show that decellularized diaphragmatic tissue reseeded with bone marrow mesenchymal stromal cells (BM-MSCs) facilitates in situ regeneration of functional tissue.

Experimental orthotopic transplantation of a tissue-engineered oesophagus in rats.

A tissue-engineered oesophageal scaffold could be very useful for the treatment of pediatric and adult patients with benign or malignant diseases such as carcinomas, trauma or congenital malformations. Here we decellularize rat oesophagi inside a perfusion bioreactor to create biocompatible biological rat scaffolds that mimic native architecture, resist mechanical stress and induce angiogenesis. Seeded allogeneic mesenchymal stromal cells spontaneously differentiate (proven by gene-, protein and functional evaluations) into epithelial- and muscle-like cells.

Preservation of aortic root architecture and properties using a detergent-enzymatic perfusion protocol.

Aortic valve degeneration and dysfunction is one of the leading causes for morbidity and mortality. The conventional heart-valve prostheses have significant limitations with either life-long anticoagulation therapeutic associated bleeding complications (mechanical valves) or limited durability (biological valves). Tissue engineered valve replacement recently showed encouraging results, but the unpredictable outcome of tissue degeneration is likely associated to the extensive tissue processing methods.
