Who found some new mechanisms of HBV virulence?
This dreadful HBV is small in size. The genome of this virus is a partial double stranded circle. When made fully double stranded, this genome carries about 3000 base pairs, compared to 200 kilo base pairs of the genome of the smallpox virus.   view more (2008-02-25)

A stepwise retreat: how immune cells catch pathogens
To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria.   view more (2007-07-12)

More girls than boys benefit from breastfeeding, Hopkins Children's research shows
Challenging the long-standing belief that breast-feeding equally protects all babies against disease, research led by Johns Hopkins Children's Center investigators suggests that when it comes to respiratory infections, the protective effects of breast milk are higher in girls than in boys.   view more (2008-06-02)

Scientists Discover How Fish Evolved To Float At Different Sea Depths
Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths.   view more (2005-03-18)

Stem cells and cancer: cancer pathways that also control the adult stem cell population
Speaking today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh, Professor Alan Clarke from Cardiff University describes his work to investigate a mechanism that normally drives adult stem cells to repair the intestine.   view more (2008-04-10)

Brain tissue reveals possible genetic trigger for schizophrenia
A study led by scientists from the University of North Carolina at Chapel Hill may have identified a molecular mechanism involved in the development of schizophrenia.   view more (2007-03-29)

Helicobacter pylori inhibits intercellular communication of cultured gastric cells
The formation of a cancer is proven to be a multi-stage, multi-mechanism process by animal and human studies. As a definite carcinogen, the role of Helicobacter pylori (H pylori) in the formation of gastric cancer has been unclear.   view more (2007-10-29)

Researchers cast doubt on hypothesis that stigma fuels HIV epidemic
The dominant view in the public health community is that the stigma of being HIV positive fuels the HIV epidemic, and yet there is a lack of evidence to support this view.   view more (2006-10-31)

UCLA imaging study of children with autism finds broken mirror neuron system
New imaging research at UCLA detailed Dec. 4 as an advance online publication of the journal Nature Neuroscience shows children with autism have virtually no activity in a key part of the brain's mirror neuron system while imitating and observing emotions.   view more (2005-12-05)

Mechanism for the in-vivo transport of siRNA
It all started with flowers: in the nineties of the last century Norwegian researchers discovered that additional copies of a particular gene in petunias inhibited its activity instead of reinforcing it as had been assumed.   view more (2007-09-18)

Helicobacter pylori - the key behind its recognition is somewhere else
The first step against infection is the detection of microorganisms capable of causing disease. This is done through the recognition of molecular structures not shared by the host, but also present in other harmless or even useful microbes. A question that has puzzled scientists for many years is... view more (2004-10-29)

Newly-identified exercise gene could help with depression
Boosting an exercise-related gene in the brain works as a powerful anti-depressant in mice-a finding that could lead to a new anti-depressant drug target, according to a Yale School of Medicine report in Nature Medicine.   view more (2007-12-03)

A potential sugar fix for tumors
Researchers at the Duke School of Medicine apparently have solved the riddle of why cancer cells like sugar so much, and it may be a mechanism that could lead to better cancer treatments.   view more (2008-04-16)

Newly found sensing system enables certain bacteria to resist human immune defenses
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health, have discovered a survival mechanism in a common type of bacteria that can cause illness.   view more (2007-06-08)

Blood cells linked to heart attacks, other inflammatory diseases
Two human blood cells that help fight blood loss, infection, and inflammation are responsible as well for starting a series of molecular events that results in overproduction of Cox-2, an enzyme involved in heart attack, stroke, atherosclerosis, and other inflammatory diseases.   view more (2006-10-09)

Biologists learn structure of enzyme needed to power 'molecular motor'
Researchers at Purdue University and The Catholic University of America have discovered the structure of an enzyme essential for the operation of "molecular motors" that package DNA into the head segment of some viruses during their assembly.   view more (2007-03-23)

Genetic double-agents unmasked
Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer.   view more (2004-10-26)

Metformin increases pathologic complete response rates in breast cancer patients with diabetes
Metformin, the common first-line drug for type 2 diabetes, may be effective in increasing pathologic complete response rates in diabetic women with early stage breast cancer who took the drug during chemotherapy prior to having surgery, paving the way for further research of the drug as a potential... view more (2008-06-03)

Newly Identified Mechanism Helps Explain Why People of African Descent Are More Vulnerable to Tuberculosis
A team of scientists has identified a cellular mechanism that may help explain the puzzle of why people of African descent are more susceptible to tuberculosis infection and why, once infected, they develop more severe states of the disease than whites.   view more (2006-02-27)

Study reveals why certain ovarian cancers develop resistance to platinum-based chemotherapy
A team of researchers led by Fred Hutchinson Cancer Research Center has identified a new mechanism that explains why some recurrent ovarian tumors become resistant to treatment with commonly used platinum-based chemotherapy drugs such as cisplatin and carboplatin. They describe their research... view more (2008-02-11)

Stem cells may solve mystery of early pregnancy breast cancer protection
The answer to why an early pregnancy seems to protect against breast cancer could rest with a decrease in stem cells found after animals have given birth, said researchers at Baylor College of Medicine in a report that appears in the current issue of the journal Stem Cell.   view more (2008-09-17)

Poison digs its own grave
Botrytis cinerea (grey mould) has a large arsenal of molecular pumps at its disposal to protect it against toxic substances such as antibiotics, plant defence compounds and fungicides. Dutch researcher Henk-jan Schoonbeek saw how the fungus started to pump out certain toxic substances within just... view more (2004-12-16)

Oncoproteins double-team and destroy vital tumor-suppressor
Two previously unconnected cancer-promoting proteins team up to ambush a critical tumor suppressor by evicting it from the cell's nucleus and then marking it for death by a protein-shredding mechanism, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the... view more (2008-02-15)

HIV is a 'double hit' to the brain
New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia.   view more (2007-08-16)

There goes the neighborhood: Vascular niche nurtures brain tumor stem cells
Self-renewing cancer stem cells (CSCs) comprise only a tiny fraction of most brain tumors, but eliminating them is likely to have a profound impact on the ability of a tumor to survive and grow.   view more (2007-01-17)
