UC Davis researchers discover key to body's ability to detect subtle temperature changes
02-26-2007 · EurekAlert!Scientists have long known the molecular mechanisms behind most of the body's sensing capabilities. Vision, for example, is made possible in part by rhodopsin, a pigment molecule that is extremely sensitive to light. It is involved in turning photons into electrical signals that can be decoded by the brain into visual information. But how the human body is able to sense a one-degree change in temperature has remained a mystery.

- Elderly's ability to manage the cold may be due in part to some aging processes of the body
01-18-2007 · EurekAlert!
Hypothermia -- when the body's temperature drops significantly below normal -- is especially deadly for the elderly. Older people become hypothermic despite the fact that they are more likely to live inside a home than on the street, and nearly half who become hypothermic die. By contrast, children rarely succumb to the disorder. In a recently published study researchers have found that certain characteristics, which change with age, affect younger and older persons differently.

- University of Iowa team discovers first moisture-sensing genes
11-07-2007 · EurekAlert!
Researchers in the University of Iowa Roy J. and Lucille A. Carver College of Medicine have discovered the first two genes involved in moisture sensing (hygrosensation). The discovery also reveals a 'two-sensor' hygrosensing system in fruit flies that may allow the flies to detect subtle changes in humidity -- an ability that is critical for the flies' survival.

- Probe to detect spread of breast cancer co-developed by UH scientist
03-06-2007 · EurekAlert!
High-temperature superconductors hold the key to a handheld tool for surgeons that promises to be more accurate, cost-effective and safer than existing methods for staging and treating various cancers, including breast cancer. Researchers at University of Houston and University College of London have developed a novel detection procedure, combining nanotechnology and advanced magnetic sensing based on high-temperature superconductors, enabling surgeons to more effectively locate the sentinel lymph node.

- UCSD researchers discover internal compass of immune cell
12-14-2006 · EurekAlert!
Researchers at the UCSD School of Medicine have discovered how neutrophils -- specialized white blood cells that play key roles in inflammation and in the body's immune defense against bacteria -- navigate to sites of infection and inflammation. These findings could potentially lead to new treatments for serious infections and inflammatory diseases in patients.

- Penn researchers discover how key protein stops inflammation
08-07-2007 · EurekAlert!
Researchers recently identified how a regulatory protein called Bcl-3 helps to control the body's inflammation response to infection by interfering a critical biochemical process called ubiquitination. Their findings open new avenues for developing therapies to treat such diseases as sepsis, diabetes and rheumatoid arthritis.

- Scientists discover how cancer may take hold
09-24-2007 · EurekAlert!
A team, led by researchers at the Carnegie Institution, has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated. The research shows how the biomolecules responsible for healthy T cells, the body's first defenders against hostile invaders, are quashed, permitting the invading cancer to spread. The same cycle could also be involved in autoimmune diseases such as multiple sclerosis.

- Researchers discover 'acquired' DNA key to certain bacterial infection
06-18-2007 · EurekAlert!
Researchers announced this week the discovery of a mechanism by which Mycobacterium avium -- a bacterium which can result in serious lung infections and is prevalent in emphysema and AIDS patients among others -- infects tissue cells or "macrophages" and thus compromises the body's immunity.

01-11-2008 · EurekAlert!
UCLA researchers have found that a key protein in the body's dendritic cells can stop the virus that causes AIDS from "budding" -- part of the virus' life cycle that is crucial to its ability to replicate and infect other cells.

- Targeting gut bugs could revolutionize future drugs, say researcher
02-01-2008 · EurekAlert!
Revolutionary new ways to tackle certain diseases could be provided by creating drugs which change the bugs in people's guts, according to a new article. Trillions of bugs known as gut microbes live symbiotically in the human gut. They play a key role in many of the processes that take place inside the body. Different people have different types of gut microbes living inside them and abnormalities in some types have recently been linked to diseases such as diabetes and obesity.
