Abstract Purpose Development of ultra-high-performance liquid chromatography-triple quadrupole tandem mass spectrometry method for quantification 4-fluoroisobutyryl fentanyl (4-FiBF) and its distribution in postmortem biological samples four fatal intoxication cases, which occurred September 2018, Poland. Methods Biological fluids (blood, urine, vitreous humor, bile, gastric content) tissues (b...

In this study granulocyte-macrophage colony stimulating factor (CSF) was prepared from rabbit and guinea pig lung tissues. The biological activity of these CSFs was measured on semisolid agar culture and compared with those of mouse and rat. Weight of animals, incubation time and cross-reactivity of CSFs with different bone marrow sources were also investigated. The results showed that both...

Tissue Engineering When engineering tissues in vitro it is essential to mimic the heterogeneity present native tissues, both composition and biological components. While different approaches manufacturing technologies are used literature, bioprinting holds great promise, being able recapitulate complex architectural 3D features use bioinks support requirements. These considerations reviewed art...

Many biological and physiological events, including growth, development, metabolism of reproductive non-reproductive tissues in men women, are regulated by estrogens estrogen receptors (ERs) [...]

Introduction: In laser surgery, the laser beam can evaporate and cut the tissue like a small surgical knife when the tissue temperature is heated to 100 degrees Celsius. a complete understanding of the distribution of damage in both pathologic tissue and surrounding tissue is necessary. Although the test is the most realistic solution for treating medical problems, for this rea...

peripheral nerve injuries (pni) can lead to lifetime loss of function and disfigurement. different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. utilization of absorbable and non-absorb...
