Scientists at Galileo Pharmaceuticals confirm inflammatory response linked to glucose levels

...n set up a test of nearly 400 small molecules that fit their criteria. The test results showed three small molecules that can inhibit the enzyme. These are candidates for development as drugs. Kosik explained that proteins are strings of amino acids folded into small globs. All proteins that happen to b...

Men Estimate Men's Risks Of Common Disorders Higher Than Women Do, And Vice Versa

...sease, cancer, mental illness and accidents, to be fit and to live longer. The research provides insights about gender identity and difference. They found that each gender tends to think risks are higher for their own sex than for the other gender. Previous studies suggest that lay people and health pro...

What comes first…the chicken, the egg, or the bad attitude?

...ry of the exceptional "super-mom" birds that don't fit the textbook norm has opened new doors in the research program. "If the offspring of these special hens are also more efficient, the broiler industry could move forward in leaps and bounds. As a result of their findings, Robinson, Renema and Zuidhof...

Researchers identify new catfish family

...s. They said Lacantunia enigmatica appears not to fit any of those patterns and thus the name of the species reflects the mystery surrounding its origins and relationships. The generic name of the fish reflects its distribution in the Río Lacantún drainage, flowing through the Montes Azules and Selva L...

UIC developing drug for SARS

...s, revealing whether and how tightly the molecules fit in the space. If the fit is poor, he can explore a library of alternative molecules that might meet the chemical and configur...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

... have a receptor on their surface that's a perfect fit for a particular cytokine, interleukin-1, or IL-1. Like a switch, when IL-1 binds to this receptor, the cell unleashes additional biochemical agents, which in turn cause more local inflammation. As inflammation builds, patients experience progressive...

Nanotubes inspire new technique for healing broken bones

... or synthetic material is shaped by the surgeon to fit the affected area, according to Haddon. Pins or screws then hold the healthy bone to the implanted material. Grafts provide a framework for bones to regenerate and heal, allowing bone cells to weave into the porous structure of the implant, which sup...

Did humans cause ecosystem collapse in ancient Australia?

...human-induced change in the vegetation is the best fit to explain what happened at that critical juncture." ...

NYU biologists map out early stages of embryo formation

...the molecular level, describing how its components fit together both physically and logically. "These results point to a high level of coordination among a relatively small number of molecular machines required for proper early embryonic development in C. elegans," said Fabio Piano, an assistant profess...

Exercise aside, genes may ultimately dictate seniors' mobility

...the DD and ID genotypes were more likely to remain fit than those with the II genotype, who developed mobility problems at a 45 percent higher rate, researchers found. No difference in mobility according to genotype was found among non-exercisers, suggesting function was influenced by an interaction betw...

New book expands biological classifications to account for 'alien' life

...account for a variety of life forms that would not fit in the current system. Among them are viruses, long considered to be non-living bits of protein and nucleic acid but which Ward argues are as alive as the many parasites that infect humans and other organisms. The revamped classification system also...

Scientists and engineers apply nature's design to human problems

...ty. We used the analogy of a new species trying to fit into a community as a way to think about what our center could do to increase the productivity of the Tech 'ecosystem.'" As CBID encourages interaction among its initial 17 members, Yen expects an increase in biomimetic research ?that is, research i...

Costly breeding programs for endangered species pay off

...ressful environment served to select only the most fit lines while the more benign environment allowed low-fitness lines to persist in captivity," said Meffert. Though the findings clearly support the case for expensive MAI breeding schemes for some endangered animals, Meffert suspects that might not be...

Biologist Discovers What May Be World’s ‘Pickiest?Mates

...era said. “Crabs enter burrows sideways so have to fit in front to back and top to bottom.?/p> When a female has found a mate and burrow to her liking, typically one that is about the same size as she, either she or the male will plug up the opening of the burrow and the couple will mate and incubate...

DNA size a crucial factor in genetic mutations, study finds

...ponding base to create a new base pair. DNA bases fit into a specialized site on the enzyme before they are bonded to the template. Kool wanted to see how the enzyme reacts if the bases are not the usual size. ''The idea was to see how DNA replication depends on size,'' Kool says. The researchers inves...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

... DNA molecule. Thousands of nanotubes could easily fit inside a typical cell. "An interesting property of carbon nanotubes is that they absorb near-infrared light waves, which are slightly longer than visible rays of light and pass harmlessly through our cells," Dai says. But shine a beam of near-infrar...

Mammalian Transcriptome Mapped

...oes not encode for proteins and therefore does not fit into the classical definition of a gene.) While Wahlestedt and his consortium colleagues found 20,714 protein-encoding RNA transcripts--which was what the scientists expected, since there are about 22,000 genes in the human genome--they found an even...

DNA self-assembly used to mass-produce patterned nanostructures

... scientists specified 16 unique puzzle pieces that fit together as a 4x4 grid that formed a puzzle spelling the letter "D." Because each piece would only match up with its predetermined neighbors, the scientists could mix together a trillion of each type of tile in one batch to generate a trillion 4x4 gr...

Many needles, many haystacks

...tif. Finding such motifs and predicting where they fit in is like looking for needles in haystacks." Or like looking at a line of automobiles and trying to decide which one a bulky motor fits into ?versus trying to find where a tiny screw goes. Linear motifs are so small that it is hard to tell what fea...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

... a few years, the technology could be downsized to fit into a hand-held portable device the size of a cell phone or PDA and taken into remote areas around the world to test for lethal strains of flu. "We can make it small and simple enough to take into rural areas in places like the Congo, Cambodia or...
