Cellular Autolysis in Intrapartum Death. Some Structural Characteristics
نویسندگان
چکیده
Asphyxia is one of the implicit causes of intrapartum death. The most affected are the organs of respiratory and digestive systems, filled with different substances or structures of the feto-maternal metabolism. Inside these organs, the cells of the mucosal epithelium suffer cellular autolysis and are completely removed. The loss of structure can reach the depths of the mucous membrane. In some organs on the normal skeleton we can observe regions of cellular autolysis (kidneys).

Contribution of cellular autolysis to tissular functions during plant development.
Plant development requires specific cells to be eliminated in a predictable and genetically regulated manner referred to as programmed cell death (PCD). However, the target cells do not merely die but they also undergo autolysis to degrade their cellular corpses. Recent progress in understanding developmental cell elimination suggests that distinct proteins execute PCD sensu stricto and autolys...
متن کاملDifferential roles of the ChiB chitinase in autolysis and cell death of Aspergillus nidulans.
Autolysis is a natural event that occurs in most filamentous fungi. Such self-degradation of fungal cells becomes a predominant phenomenon in the absence of the regulator of G protein signaling FlbA in Aspergillus nidulans. Among a number of potential hydrolytic enzymes in the A. nidulans genome, the secreted endochitinase ChiB was shown to play a major role in autolysis. In this report, we inv...
متن کاملMorphology of heart valves preserved by liquid nitrogen freezing.
As a preliminary to establishing a frozen valve bank for replacement surgery, the possible effects of the proposed freezing and thawing procedure on tissue structure were assessed in 16 human pulmonary valves removed from cadavers at necropsy and nine dog valves obtained fresh. The valves were frozen and stored in liquid nitrogen for intervals ranging from 23 to 380 days. Blocks of tissue cut f...
متن کاملAcinar autolysis and mucous extravasation in human sublingual glands: a microscopic postmortem study
UNLABELLED Although some morphological investigations on aged human sublingual glands (HSG) found eventual phenomena identified as autolysis and mucous extravasation, the exact meaning of these findings has not been elucidated. OBJECTIVE The aim of this work is to investigate whether acinar autolysis and mucous extravasation are related to the aging process in human sublingual glands. We also...
متن کاملA clinico-neuropathological study on brain death.
A clinico-neuropathological study was conducted on 60 cases of brain death, 36 males and 24 females, ranging in age from 11 to 81 years, the average being 49.4 years. Of these, 29 patients died of cerebrovascular disease. The average duration of brain death was 99 hours. The mean weight of the brain was 1466 g. Neuropathological findings were brain edema, congestion, herniation and various suba...
