Background: As it is known, the anatomy of the vessels is examined by removing the cast of the vessels inside the organs. Generally, liquid material (polyester, takilon, etc.) is injected into the vessels with positive pressure to remove the cast from the vessels of the organs. We built a machine to remove the cast of the vessels inside the organ. We named it corrosion machine.
Materials And Methods: Sheep kidneys were used in our experiment. After the kidneys were cannulated, they were placed in the vacuum chamber. With the operation of the vacuum pump, negative pressure was created in the vacuum chamber. With negative pressure, kidneys and its vessels expanded. Takilon or polyester easily entered the vessels of the kidney. The cast of the vessels of the kidney was removed. With this newly developed technique, the anatomy of the vessels whose casts were removed was examined with the naked eye, stereomicroscope or SEM.
Results: The corrosion machine we built can cast the vessels of the organs very well. Takilon or polyester (which we used in our experiment) easily entered the capillaries under the effect of negative pressure.
Conclusions: We think that this method can also be applied to other organs and used in vascular research.

Background: In children and adults with sickle-cell disease (SCD), acute ischemic stroke (AIS) associated with a vaso-occlusive crisis is a leading cause of physical and cognitive disability and death. However, neurological guidelines for acute management of AIS fail to directly address this issue. We here report a case of a man with severe cerebrovascular complications and illustrate the current evidence on the management of SCD-related AIS.

The Bawean deer () is a small deer species endemic to the island of Bawean in Indonesia. The species is listed as critically endangered by the IUCN Red List. The current population is assessed to be less than 500 adults living in the wild.

Morphological observations of their endocranial structures allow for outlining some of the early steps of the evolutionary history of the cetacean brain. The external features of the brain and associated sinuses of Raoellidae are so far only documented by the virtual reconstruction of the endocast based on specimens of the species Indohyus indirae.

People tend to be bad at detecting lies: When explicitly asked to infer whether others tell a lie or the truth, people often do not perform better than chance. However, increasing evidence suggests that implicit lie detection measures and potentially physiological measures may mirror observers' telling apart lies from truths after all. Implicit and physiological responses are argued to respond to lies as a threatening stimulus associated with a threat response.

The Western European Hedgehog (Erinaceus europaeus) is a small, nocturnal, insectivorous mammal native to Europe. The aim of the study was to describe the arterial supply to the head of the Western European hedgehog in detail and compare it with known vascular patterns found in mammals. In the study, 30 specimens of adult Western European hedgehogs were used.
