Congenital Anomalies and Teratology
Congenital anomalies are structural or functional defects present at birth, caused by genetic factors, teratogens or disruptions during embryogenesis.
BiologyEmbryogenesis and Tissue Differentiation
Embryogenesis describes the formation of germ layers and their differentiation into tissues and organs through coordinated gene expression and cell signaling.
BiologyHistology of the Placenta and Fetal Membranes
Placental histology examines maternal-fetal interface structure, evaluating villous maturation, vascular development and pathological changes.
BiologyPediatric Neoplasms
Pediatric neoplasms are embryonal tumors that recapitulate developing tissues, classified by histology, IHC and molecular alterations distinct from adult cancers.
BiologyStem Cells and Tissue Regeneration
Stem cells maintain and repair tissues through self-renewal and differentiation, with histological identification guiding regenerative medicine applications.
BiologyEnzyme Histochemistry in Muscle and Nerve Biopsy Diagnosis
Enzyme histochemistry on muscle and nerve biopsies identifies fiber types, mitochondrial function and metabolic activity essential for neuromuscular diagnosis.
BiologyHistochemical Detection of Metals and Minerals
Histochemical methods detect metal ions and mineral deposits in tissue sections, diagnosing iron overload, copper storage disease and heavy metal toxicity.
BiologyIn Situ Hybridization
In situ hybridization detects specific DNA and RNA sequences within intact tissue sections, combining molecular specificity with morphological context.
BiologyOxidative and Hydrolytic Enzymes in Tissue
Oxidative and hydrolytic enzyme histochemistry localizes metabolic and catabolic enzyme activity in tissue sections for diagnostic pathology.
BiologyPrinciples of Enzyme Histochemistry
Enzyme histochemistry detects enzymatic activity in tissue sections, localizing functional proteins to specific cells and subcellular compartments.
BiologyFrozen Section Technique
Frozen section is a rapid histopathological technique that provides intra-operative diagnosis within minutes, guiding surgical decision-making.
BiologyHistological Staining Techniques
Histological staining techniques use dyes and chemical reactions to visualize tissue components, enabling microscopic identification of normal and pathological structures.
