The repair and remodeling of injured tissues, known as wound healing, is a multifaceted process. The use of nanotechnology to speed up the healing process of wounds by promoting the right kind of mobility through different mechanisms has shown a lot of promise. Several nanotechnologies with novel properties have emerged in recent years, each of which targets a different issue associated with wound-healing processes. Through their antibacterial, anti-inflammatory, and angiogenic actions, nanomaterials may alter the wound microenvironment from a non-healing to a healing state. Wound dressings including hydrogels, gelatin sponges, films, and bandages may all benefit from the use of nanoparticles (NPs) to keep harmful microbes out. The addition of bioactive substances like antibiotics, NPs, and growth factors to certain dressings may further boost their efficacy. In conclusion, this review sheds light on wound healing that may be aided by the special features of materials based on nanotechnology. Although nanomaterials for wound healing show great promise, further study is needed before this promising area can convert its findings into consumer-friendly solutions.

In human, mice and different veterinary species, T cells are subdivided into phenotypically different subpopulations based on their expressed T cell receptor and cell specific surface markers. As no data were available regarding the existence of T cell subpopulations in the peripheral blood of dromedary camels, the current study aimed at the identification of camel blood T cell subpopulations and the analysis of their adhesion molecules expression patterns. Using monoclonal antibodies crossreactive with camel CD antigens, camel blood WC1-positive T cells and CD4- positive αβ T cells and their expression pattern of adhesion molecules were identified by flow cytometry. Under camel CD4-positive T cells, a major fraction (83%) with naïve phenotype (CD4+ CD11alo CD44lo) and minor fraction (13%) with effector phenotype (CD4+ CD11ahi CD44hi) were identified. In addition, the analysis of age related effects on the proportion of lymphocyte subsets indicates that camels belong to the T cell high species. [ABSTRACT FROM AUTHOR]
