Are the Lungs Passive Organs?

P-13: Male Reproductive Organs Are at Riskfrom Environmental Hazards

Background: Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time periods past 50 years. Materials and Methods: Except for testicular cancer this evide...

Cutting Edge: Secondary Lymphoid Organs Are

Cardiopulmonary physiology: why the heart and lungs are inextricably linked.

Because the heart and lungs are confined within the thoracic cavity, understanding their interactions is integral for studying each system. Such interactions include changes in external constraint to the heart, blood volume redistribution (venous return), direct ventricular interaction (DVI), and left ventricular (LV) afterload. During mechanical ventilation, these interactions can be amplified...

How Are the Sizes of Cells, Organs, and Bodies Controlled?

PLoS Biology | http://biology.plosjournals.org Why is an elephant bigger than a mouse? Why, luckily, are our arms precisely the same size? While developmental genetics over the past 20 years has provided us with fascinating insights into how segments form, limbs bud, and axons find their targets, we have made little progress towards answering these obvious questions in biology. Rather than atte...

The Significance of Hemosiderin Deposition in the Lungs and Organs of the Mononucleated Macrophage Resorption System in Infants and Children

Hemosiderin deposition is not often recognized on routine examination with hematoxylin and eosin staining; however, iron stains may be helpful in the evaluation of hemosiderin deposition in infant autopsies. This report describes the data obtained from autopsy of 86 infants and children whose deaths were investigated at the Forensic Medicine Council Bursa Morgue Department from January 2000 to ...
