3 and a fraction mayor may not respond to treatment. On the behavioral level, animal research shows that a variety of experimental conditions can induce de pression. The same is true in the field of treatment, where pharmacologically highly different drugs can equally alleviate depression in animals and hu mans. The question as to whether this is due to a heterogeneity of depressive subjects based on different pathogenetic mechanisms is open to discussion. We can look for common features of all possible causal factors in the hope of finding a single basic mechanism. Many divergent findings may also be ex plained as peripheral changes of a highly complicated dynamic system. In the field of psychopharmacology, a circular reasoning has become evident in the sense that originally the clinical antidepressive response was founded on empirical grounds only. In a second step, an attempt was made to characterize some clinically active compounds pharmacologically, and in a third, further compounds were developed based on aspects of the pharmaco logical profiles. Moreover, the post hoc development of a pharmacological screening method has the serious disadvantage of delaying breakthroughs into new fields."

The Nature Of Pure Activity In Two Series, Book One And Book Two.

Of the various subspecialty areas in anatomic pathology, neuropathology tends to be one of the least familiar to general pathologists. Most surgical pathologists at institutions with neurosurgical practices gain quick familiarity with the common tumours of the central nervous system. Non-neoplastic diseases of the central nervous system, however, continue to remain a mystery to surgical pathologists, since non-neoplastic diseases of the nervous system represent a wide spectrum of relatively uncommon diseases that are not often biopsied. This volume has been biased toward diseases that may be encountered in surgical pathology practice. Moreover, the authors have tried to illustrate as many entities as possible with surgical material, and have used autopsy brains primarily to illustrate key macroscopic features of some diseases. Readers will find the book of use and comfort as they realise that the brain biopsy in front of them is not from a familiar neoplasm, but from one of the sometimes challenging, and always fascinating, non-neoplastic diseases of the central nervous system.

The hunting, fishing, growing-up stories in "Emergency Toilet Paper" will make you say, "Hey! I did that when I was a kid and I knew it was funny...Just knew it! So why the hell did I get grounded?!" "Emergency Toilet Paper" digs into the mind of the sportsman and pulls out all the goo that makes us, umm, "special". It also helps to prove long-debated theories of the outdoor world, such as: bears on the high plains, aliens just waiting to abduct anyone with a six pack and a mind for a fishing trip, and the actual existence of the fabled "caring spouse" of an outdoorsman...OK, OK. That last one may have been a little far-fetched, but if there are any spouses out there that want to at least appear as though they care, try picking up some Emergency Toilet Paper for your beloved outdoorsman. However, be careful, you might want to first suggest they read it.
