Heme Oxygenase

Heme Oxygenase

Heme oxygenase is an enzyme which breaks down heme, the iron-containing oxygen-carrying constituent of the red blood cells. Heme must be synthesised and degraded within an individual nucleated cell, as heme is essential for the maintenance of cellular homeostasis by sensing or using oxygen. Physiological heme degradation is catalysed by the two functional isozymes of heme oxygenase, heme oxygenase-1 (HO-1) and HO-2, yielding CO, iron, and biliverdin IX N. Heme oxygenase-1 (HO-1), has potent anti-inflammatory, anti-oxidant and anti-proliferative effects, is up-regulated by multiple stimuli and provides protection against oxidative stress. HO-1 also plays an important role in the regulation of cardiovascular function and is involved in many other diseases such as sickle cell disease. This new book brings together leading research from around the world in this field.

The role of bile pigments in health and disease: effects on cell signaling, cytotoxicity and cytoprotection

Degradation of heme involves its conversion to biliverdin by heme oxygenase followed by reduction of biliverdin to bilirubin by biliverdin reductase. There is ample evidence for the pleiotropic functions of biliverdin reductase in cell signaling and regulation of gene expression. This enzyme plays a major role in glucose uptake and the stress response. Bilirubin has been shown to behave as a "double-edged sword". It can exert either cytotoxic or cytoprotective effects, depending on the blood and/or tissue concentration of its free fraction, the nature of the target cell or tissue, and the cellular redox state. Its antioxidant effect is the basis for the proposed cardioprotective effect of relatively low blood concentrations of bilirubin in humans with moderate hyperbilirubinemia. This Special Topic forum is intended to serve as a platform for updating information and presenting advances in basic and clinical research in the above and related subjects.

The Vanishing Vision

This spirited history of public television offers an insider's account of its topsy-turvy forty-year odyssey. James Day, a founder of San Francisco's KQED and a past president of New York's WNET, provides a vivid and often amusing behind-the-screens history. Day tells how a program producer, desperate to locate a family willing to live with television cameras for seven months, borrowed a dime—and a suggestion—from a blind date and telephoned the Louds of Santa Barbara. The result was the mesmerizing twelve-hour documentary An American Family. Day relates how Big Bird and his friends were created to spice up Sesame Street when test runs showed a flagging interest in the program's "live-ac...

Recovering a Public Vision for Public Television

In 1995, US public television faced possible elimination of federal funding, potentially commercialising this type of broadcasting. This study suggests that these strains have undermined public broadcasting historically; the result is that programming no longer prioritises social reform.

The CTSA Program at NIH

In 2006 the National Institutes of Health (NIH) established the Clinical and Translational Science Awards (CTSA) Program, recognizing the need for a new impetus to encourage clinical and translational research. At the time it was very difficult to translate basic and clinical research into clinical and community practice; making it difficult for individual patients and communities to receive its benefits. Since its creation the CTSA Program has expanded, with 61 sites spread across the nation's academic health centers and other institutions, hoping to provide catalysts and test beds for policies and practices that can benefit clinical and translation research organizations throughout the cou...

Getting Off at Elysian Fields

No city in America knows how to mark death with more funerary panache than New Orleans. The pageants commemorating departed citizens are often in themselves works of performance art. A grand obituary remains key to this Stygian passage. And no one writes them like New Orleanian John Pope. Collected here are not just simple, mindless recitations of schools and workplaces, marriages, and mourners bereft. These pieces in Getting Off at Elysian Fields: Obituaries from the New Orleans “Times-Picayune” are full-blooded life stories with accounts of great achievements, dubious dabblings, unavoidable foibles, relationships gone sour, and happenstances that turn out to be life-changing. To be sur...
