Abstract:

This is a fatal case of multiple complicated congenital anomalies displaying several symptoms consistent with hydrolethalus syndrome. The newborn’s phenotype is characterized by a combination of serious anatomical abnormalities such as open-book cerebral hemispheres, defective lobulation of the lungs (one lobe on the left, two on the right), a smaller right kidney, a smooth cerebral surface, and a specific keyhole-shaped defect in the skull base, primarily associated with hydrocephalus.

The purpose of this study was to investigate the distribution and ultrastructure of Merkel cells on the ocular surface and study changes in their number and ultrastructure after corneal epithelial wounding.

The study focuses on the origin and survival of the so-called lobed ware in the Far East. The term refers to vessels decorated with shallow vertical grooves, less often with deep, wide dents, either on the most convex part of the body or on the entire surface. Some vessels are covered with groups of vertical carved lines or burnished, less often painted bands imitating lobulation. Such ceramics are especially frequent at sites of the Jurchen era (7th–13th centuries) in the Amur basin. They are also found in Primorye, northeastern China, and in adjacent territories.

Introduction: Spleen is the largest and secondary lymphoid organ in humans. It has two ends: Anterior and Posterior end. Two surfaces: Visceral and Diaphragmatic surfaces. Three borders: Superior, Inferior and Intermediate. Spleen begins to develop during the 5th week of intra-uterine life from a mass of mesenchymal cells, originating in the dorsal mesogastrium as a localized thickening of coelomic epithelium. The spleen is lobulated in foetus but the lobules normally disappear before birth. The imperfect fusion of splenic masses during embryonic life results in an accessory spleen. The spleen

These cells also exhibit similar changes to their nuclear structure, at least during the early stages of differentiation when their nuclei become indented or kidney-shaped. While reg

By electron microscopy, it was determined that schizogony occurred in 4 stages. The earliest stage was the presence of a multilobed structure containing finely granular protoplasm in the cytoplasm of the macrophage.

Objectives: Adult spleens show extensive morphological variation, with a reported prevalence of 40–98% clefts (also called notches or fissures) on the splenic surface and 10–30% accessory spleens at autopsy.

According to this hypothesis, fusion of the spleen primordia is completed after birth and spleen morphological variations are often explained as stagnation of spleen development at the fetal stage.
