Scientists learn to predict protein-stabilizing ability of small molecules

...of the robotic arms holds a tiny video camera, one works as a retractor and the other two replicate the surgeon’s exact hand movements. The camera and instruments are inserted through small keyhole incisions in the patient’s abdomen. The surgeon then directs the robotic instruments to dissect the prostate ...

Cells from amniotic fluid used to tissue-engineer a new trachea

...er than adult healing." Fauza, whose research lab works closely with Children's Advanced Fetal Care Center, has been investigating the idea of growing new tissues and organs for these tiny patients for eight years. Since the tissue-engineered grafts are made from the baby's own cells, taken before birth, ...

Compound from marine bacteria shows potential as multiple myeloma therapy

...tivities than bortezomib, say the researchers, and works at lower doses. NPI-0052 also appears to be less toxic to normal cells. Bortezomib is currently given by intravenous infusion. "NPI-0052 can be given orally, although the first clinical trials will be using the intravenous route," says Paul Richard...

Some good news for the world's poor

...igler. The paper's lead author, Dr. Shenggen Fan, works at IRRI's sister institute, the Washington-based International Food Policy Research Institute (IFPRI). In his paper, Dr. Fan said: "The results indicate that rice varietal improvement research has contributed tremendously to increases in rice product...

Sea slug mixes chemical defense before firing at predators

...her microbes. "As we learn more about how escapin works in Aplysia, we will hopefully be able to reproduce its chemical properties in the laboratory," said Derby. In addition to Derby, co-authors of the Journal of Experimental Biology study are Paul Johnson, PhD, Cynthia Kicklighter, PhD, Manfred Schmidt...

RNA splicing occurs in nerve-cell dendrites

...s) and introns (non-coding regions). mRNA splicing works by cutting out introns and merging together the remaining exon pieces, resulting in an mRNA capable of being translated into a specific protein. The vast array of proteins within the human body arises in part from the many ways that mRNAs can be s...

Asleep in the deep: Model helps assess ocean-injection strategy for combating greenhouse effect

... liquid-gas transition depth---assuming everything works perfectly," said Zhang, a professor of geological sciences. However, at a high injection rate, seawater full of CO2 droplets would have an average density smaller than that of surrounding seawater, creating conditions that could lead to a rapidly-ris...

Mouse study: New muscle-building agent beats all previous ones

...g point for the myostatin protein, and it probably works in part by mopping up myostatin so it can't exert its muscle-inhibiting influence. But the researchers' experiments also show that the new agent's extra potency stems from its ability to block more than just myostatin, says Lee. "We don't know how ...

Texas scientists discover how a hepatitis C protein promotes liver cancer

...effective treatment available, interferon therapy, works only about half the time and often causes debilitating side effects. Those who fail treatment are at risk for fatal cirrhosis or developing liver cancer. Researchers have known for a long time that hepatitis C virus infection can lead to liver cance...

A salty tale: New bacterial genome sequenced from ancient salterns

...ed in archaea. A photosynthetic protein, rhodopsin works as a proton pump, capturing light energy and using it to move protons across the membrane and out of the cell. In doing so, the protein maintains a balance of ions inside and outside the cell. "It's very unusual to find the two different types of r...

Getting old? Slowing down? Blame inefficient mitochondria

... production," says lead author David Marcinek, who works in the department of radiology. This inefficiency means that elderly people's muscle produce less useable energy (ATP) for every unit of oxygen consumed, making normal activity seem more challenging and limiting their range of activities. ...

Free HIV tests cheaper than charging when goal is preventing AIDS
