This negative stained transmission electron micrograph (TEM) depicts a number of filamentous Marburg virions, which had been cultured on Vero cell cultures, and purified on sucrose, rate-zonal gradients. Note the virus’s morphologic appearance with its characteristic “Shepherd’s Crook” shape; Magnified approximately 100,000x.
Marburg hemorrhagic fever is a rare, severe type of hemorrhagic fever which affects both humans and non-human primates. Caused by a genetically unique zoonotic (that is, animal-borne) RNA virus of the filovirus family, its recognition led to the creation of this virus family. The four species of Ebola virus are the only other known members of the filovirus family. Marburg virus was first recognized in 1967, when outbreaks of hemorrhagic fever occurred simultaneously in laboratories in Marburg and Frankfurt, Germany and in Belgrade, Yugoslavia (now Serbia).

Surface anatomy of the human heart
The heart is demarcated by:
- A point 9 cm to the left of the midsternal line (apex of the heart)
- The seventh right sternocostal articulation
- The upper border of the third right costal cartilage 1 cm from the right sternal line
- The lower border of the second left costal cartilage 2.5 cm from the left lateral sternal line.
Human brain, medial view
There is a better view of the brainstem here. Also we can see the left lateral ventricle (the big cavity) because the septum pelucidum was removed. In the upper part of lateral ventricle a series of fringes corresponding to the transversally cut corpus callosum can be observed. Behind the brainstem there is the cerebellum. Some scientists consider the cerebellum like a computer that controls activities related to balance and motor skills, so that the rest of the brain can focus on conscience.

Human brain, lateral view
This is a real human brain fixed in formadehide. Dura was removed for a better visualization of brain circunvolutions. The human brain contains about 100 billion neurons, each making about 1000 synaptic connections with. other neurons.

Neurons in the Brain
Flashes of light may one day be used to control the human brain, and that day just got a lot closer. (WIRED Magazine Science Article)

Child with cleft lip and palate
Cleft lip and cleft palate are variations of a type of clefting congenital deformity caused by abnormal facial development during gestation. A cleft is a fissure or opening—a gap. It is the non-fusion of the body’s natural structures that form before birth. Approximately 1 in 700 children born have a cleft lip and/or a cleft palate.
A cleft lip or palate can be successfully treated with surgery, especially so if conducted soon after birth or in early childhood.
