Stumped for years by a natural filter in the body that allows few substances, including life-saving drugs, to enter the brain through the bloodstream, physicians who treat neurological diseases may soon have a new pathway to the organ via a technique developed by a physicist and an immunologist…

In the hippocampus, neural stem cells (green) sit in a layer below their progeny, the granule neurons (red). When activated by extrinsic stimuli, they enter mitosis and generate neuron progenitor cells, which eventually mature into neurons and migrate into the layer above. The number of neural stem cells in the hippocampus decreases over time, possibly contributing to the cognitive impairment associated with aging. One hypothesis is that, after a rapid series of divisions, these neural stem cells disappear via their conversion into astrocytes.

Brain slices were fixed in 4% paraformaldehyde, immunolabeled, and then cleared in FocusClear (CelExplorer, Taiwan).

Blood Cell Morphology Guide

Blood Cell Morphology Guide. This guide include lectures from CellAtlas, the online cell image database launched in 2000. The lectures provide a basic knowledge of the wide field of morphology. Each section contains a brief summary and additional links provide further explanations or addtional images.

Johns Hopkins researchers believe they may have discovered an explanation for the sleepless nights associated with restless legs syndrome (RLS), a symptom that persists even when the disruptive, overwhelming nocturnal urge to move the legs is treated successfully with medication.

Stroke vs. MS

Confusion, slurred speech, and muscle weakness can be symptoms of MS (Multiple Sclerosis), but they can also be signs of a stroke. Anyone who suddenly has trouble speaking or moving their limbs should be taken to the ER immediately. Treating a stroke within the first few hours provides the best odds of a successful recovery.

The Bog Body of “Grauballe Man”

The “Grauballe Man”, pictured above, was found in 1952 by a Dane digging for peat in Northern Europe. His throat was cut in 290 B.C., but his body was well enough preserved to yield fingerprints. Why was he killed? Maybe ritual, maybe execution for a crime, maybe human sacrifice. Here’s one odd clue: judging from his nutrition and manicure, the body appears to have been from the upper class.

The acidity of the bog water, the cold temperature, and the lack of oxygen have effectively prevented these corpses from decomposing. More than 700 bodies have been recovered, some as old as 10,000 years and some still appearing fresh enough to be mistaken for recent murder victims.

Malaria is caused by a protozoan that infests the body known as Plasmodium. This protozoan lives within the red blood cells. These protozoa are transmitted from person to person by the Anopheles mosquito, which is native to tropical and subtropical regions. There are four Plasmodium protozoan species that are responsible for causing malaria. When an infected mosquito bites a person, the parasite enters the bloodstream and travels to the liver. Once there, it grows and multiplies. While the parasite is in the liver there are no visible symptoms. The parasites multiply quickly, resulting in destruction of red blood cells. With this knowledge it is possible to choose herbal malaria treatment that can fight this disease successfully. [x]

Mummification of this homicide victim occurred after she remained in a secure bedroom in August in the southeastern United States for almost 2 weeks with no air conditioner. Mummification preserved the numerous stab wounds and incised wounds, allowing accurate postmortem assessment of her injuries.

Perthes’ Disease

  • osteonecrosis of the femoral head in a growing child
  • majority in ages 4-8yrs
  • poorly understood cause - possibly reduced blood supply to femoral head by metaphyseal vessels, rely solely on lateral epiphyseal vessels

Clinical Features

  • limping, groin pain, possibly referred to knee
  • limited + painful internal rotation, limited abduction

Investigations 

  • AP and lateral x-rays
  • bone scan
  • MRI
Management
  • ensure femoral head remains in the acetabulum - avoid long term osteoarthritis
  • bed rest when painful with NSAIDs + partial weight bearing
  • physiotherapy + swimming are encouraged, avoid high impact
  • “supervised neglect” - femoral head re-ossifies, long term risk of OA
