The Brain

Polychlorinated biphenyls (PCBs) are a ubiquitous class of environmental pollutants with toxic and hepatocellular effects, including accumulation of fat, proliferated smooth endoplasmic recticulum (SER), and concentric membrane arrays (CMAs) (1-3). The CMAs appear to be a membrane storage and degeneration organelle composed of a large number of concentric membrane layers usually surrounding one or more lipid droplets often with internalized membrane fragments (3). The present study documents liver alteration after a short term single dose exposure to PCBs with high chlorine content, and correlates them with reported animal weights and central nervous system (CNS) measures. In the brain PCB congeners were concentrated in particular regions (4) while catecholamine concentrations were decreased (4-6). Urinary levels of homovanillic acid a dopamine metabolite were evaluated (7).Wistar rats were gavaged with corn oil (6 controls), or with a 1:1 mixture of Aroclor 1254 and 1260 in corn oil at 500 or 1000 mg total PCB/kg (6 at each level).

Great Advance

Developments of disease hypotheses and conceptions of disease as philosophic entities have shown bursts of great advance. One just concluded includes emergence of bacteriology and virology culminating in Koch’s Postulates, which in the twentieth century were primary bases for disease study and colored all approaches to medicine.With recent extraordinary advances in technology, medicine faces great new obligations demanding fresh approaches and untrammeled thinking for solution of problems posed. It is clear that any approach to diseases and disabilities induced by exposures to environmental pollutants must take multiple etiology into account. For example, contributing to causation of lung malignancies one must list usual dusts, radioactivity, smog, auto exhausts, cigarette smoke and genetic composition. Consideration of plural factors in genesis of environmentally associated disease leads to the hypothesis of the incremental insult, a complex and difficult conception in which must be included provision for multiple causative agents, each contributing but a fraction toward total etiology^ Computers developed to their present refinement provide necessary tools for whatever complexity required to spawn and fructify hypotheses of inter-relating associations of incremental insults leading to pathology.

The IJCAI-09 Workshop on Learning Structural Knowledge From Observations (STRUCK-09) took place as part of the International Joint Conference on Artificial Intelligence (IJCAI-09) on July 12 in Pasadena, California. The workshop program included paper presentations, discussion sessions about those papers, group discussions about two selected topic and a joint discussion.
