Several factors influence the choice of needle and syringe: Type of injection : Intramuscular (IM) or subcutaneous (SC) Gauge of the needle : Diameter of the needle Length of the needle : Determines the depth of injection Volume of the syringe : Determines the amount of B12 to be injected 3
Hormones, in general, play a major role in maintaining your health and well-being
ESCs are derived from epiblast of the blastocyst from which many tissues of embryo arise, whereas ASCs are localized in adult organs [Table 2] where these cells function to replace damaged cells during tissue regeneration.[26,27] SCs are further classified into four types based on their transdifferentiation potential which include totipotent, pluripotent, multipotent and unipotent SC.[24] ESCs are known to have totipotent and pluripotent in nature and have the ability to differentiate into cells of three germ layers endoderm, mesoderm and ectoderm.[28] ASC is multipotent and can give rise to differentiated cells of anyone germ layer.[29] Unipotent SCs arise from multipotent cells and are dedicated to differentiate into specific type of tissue, for example, precursors for cardiomyocytes present in human heart or satellite cells characteristic for skeletal muscles are dedicated to differentiate into specific tissue.[30] Table 2
On microscopic histopathological analysis, Heinz bodies can be visualized as a result of denatured hemoglobin in peripheral blood smears with supravital staining
