Long-distance command sends human growth hormone into action

...development. Now, in findings that point toward an eventual gene therapy for the type of dwarfism that results when the pituitary gland is unable to manufacture the hormone, scientists at the University of Pennsylvania School of Medicine have found the mechanism that sets hGH in action. In addition, they've ...

In addition, Nabi is developing a second-generation version of the vaccine that is intended to address the third most common type of S. aureus, type 336, which has been identified and patented by Nabi researchers. Nabi estima...

Researchers discover gene causing deadly infantile form of genetic kidney disease

... disease (ARPKD), raising hopes of a treatment and eventual cure for infants born with ARPKD. The Polycystic Kidney Disease (PKD) Foundation provided grants that led to the promising discovery of the PKHD1 gene, an effort aided by earlier work done at the Human Genome Project. The March 2002 issue of Nature...

Scientists to examine DNA of George Washington trees

... the future, Norton said. He acknowledges that the eventual establishment of a database of genetic information may have a broader significance in the conservation of trees in the future. In this, the Washington trees will play an important role. "What better trees to serve as the foundation of this database,"...

Tiny molecular change inactivates tumor suppressor gene in neurofibromatosis

...nd of messenger RNA (mRNA). The mRNA specifies the eventual sequence of the final protein. If a reading error or nucleotide sequence change occurs as the DNA is copied into mRNA, it can change both the amino acid sequence and the properties of the final protein. These same effects can be introduced through RN...

Lyme disease ticks follow rivers in midwest

... While the movement of the ticks can predict the eventual arrival of the disease, they are not the only element of the equation, says Cortinas. Two other elements are necessary. First, small mammals, such as white-footed mice or chipmunks, which serve as a reservoir for the bacteria, must be present for...

Discovery of dynamic sub-cellular processes could lead to medical applications

...s. As expected, that resulted in the depletion and eventual disappearance of the Golgi structure. Traditional wisdom held that the proteins making up the structure traveled to the cell's outer surface, where they were absorbed. But by using sophisticated technology to mark the proteins in the Golgi apparatus,...

DNA biochip may lead to fast genetic screening, more effective drugs

...labs to understand gene-related questions, but the eventual goal is to bring the chips to market for use by doctors, possibly in three years, Gao says. She estimates the market potential for the biochip to be in the hundreds of millions to billions of dollars. "Our ambition is to become the Intel of the bio...

Scientists examine the seas our ancestors fished to better understand today's changing oceans

...d as population growth, technological advances and eventual expansion to a global market occurred. The first major human disturbance to all of the ecosystems they examined was always overfishing of the large vertebrates and shellfish. Much later other events followed: pollution, overenrichment of waters from ...

Penn study findings reverse key chronology for development of Alzheimer's disease

...age.) That leads, in turn, to cell malfunction and eventual cell death. It is known that amyloid beta protein can produce free radicals on its own, as well as stimulate other cells to do the same. Many scientists believe that a build-up of amyloid plaques causes a parallel increase in free radicals, which eve...

Carnegie Mellon University receives $1 million to create biosensor tool kit

... the university's laboratory of the same name. The eventual results of their work will give scientists the ability to create new diagnostic tools and monitor many substances simultaneously in cells cultures, living animals and patients,. For example, by packaging the tools into a small, implantable microchip,...

New reserach shows promise in conquering ulcer-causing H. pylori

... cells experienced a reversal, and eventual disappearance, of gastritis. This suggests that the healthy, mature spleen cells helped clear the animals' stomachs of the bacteria. "The persistence of H. pylori in the healthy mice was co...

...utants. The U.N. group calls for the reduction and eventual elimination of POP emissions. In December, the U.N. officials announced that 122 countries, including the U.S., have negotiated a treaty to eliminate 12 specific persistent organic pollutants. Eight pesticides (aldrin, chlordane, DDT, dieldrin, endr...

Pauling Centenary to recognize scientist, humanitarian

This set the stage for the discovery of DNA structure by Watson and Crick, who called Pauling the founder of the modern science of molecular biology. In discovering the m...

Scientists suspect new genetic risk factor for late onset Alzheimer's disease

...2, a specific form of A thought to be a marker for eventual development of late onset AD. They found that the level of A42 in the blood of family members was linked to the same small region of chromosome 10 identified in the Goate study, suggesting that the new AD susceptibility locus acts to elevate A42. ...

Human reproductive success tied to mitochondrial organization in eggs

...lier stage would be a large step in predicting the eventual success or failure of the developing embryo," said Van Blerkom. If the microtubule arrays in the egg cell do not mirror each other at the initial cell division, half of the dividing cells, or blastomeres, may carry too few mitochondria. Mitochondria...

Molecular clue to Alzheimer's mystery found

Molecular genetic studies previously linked early-onset Alzheimer's disease to mutations in three genes: amyloid precursor protein, presenilin-1 and presenilin-2. However, the biological reas...

Genetically engineered hemoglobin brings artificial blood a step closer

...he believes the product is likely to be part of an eventual blood substitute. Neither artificial blood nor its components are currently available. Several potential blood substitutes are being investigated, all of which incrementally advance development of an oxygen carrier, necessary for synthetic blood th...
