PTX3 gene. Pentraxin 3 is a member of the pentraxin taxon. This super family characterised by cyclic multimeric structure. PTX3 is produced and released by many cell sorts‚ specifically by mononucleate phagocytes‚ nerve fibre cells‚ fibroblasts and epithelium cells in response to primary inflammatory signals. PTX3 binds with high affinity to the complement element C1q‚ the living thing matrix element TNFα induced protein 6 and chosen microorganisms‚ as well as Aspergillus fumigatus and genus Pseudomonas

Plants need water for photosynthesis but they take in water through their roots so they need to transport the water up the stem to the leaves. Water is taken in by the root hairs because there is a higher water potential in the soil than in the root hairs. Then osmosis occurs to move the water from a cell with high concentration of water to a cell with low concentration through the permeable membrane. Once the water has moved down the concentration gradient it reaches a vessel called a xylem. As

A wound by true definition is a breakdown in the protective function of the skin; the loss of continuity of epithelium‚ with or without loss of underlying connective tissue (i.e. muscle‚ bone‚ nerves) following injury to the skin or underlying tissues/ organs caused by surgery‚ a blow‚ a cut‚ chemicals‚ heat/ cold‚ friction/ shear force‚ pressure or as a result

infections‚ such as blood poisoning or endocarditis (an infection of the inner lining of the heart). Pathophysiology The anatomic structure of the skin provides a barrier to infection but also opportunities for infection to occur. The squamous epithelium of the epidermis provides a water-impervious and resilient barrier against bacteria. This barrier function is the most basic and effective of the nonspecific host defenses. The surface of the skin is always colonized‚ but infection only occurs when

Provitamin B5 can play a key role in the processes of speeding up the reconstruction and healing of the epithelium‚ through its regenerative and anti-inflammatory properties. One study sought to assess how the wounds of cornea and/or conjunctiva heal after the application of a gel combination of provitamin B5 and D-panthenol. The study involved testing the activity
