The discovery of a gene mutation that causes a rare premature aging disease could lead to the development of drugs that block the rapid, unstoppable cell division that makes cancer so deadly. Scientists at the Univ. of Michigan recently discovered a protein mutation that causes the devastating disease dyskeratosis congenita, in which precious hematopoietic stem cells can't regenerate and make new blood.
Given a choice, most patients would prefer to take a drug orally instead of getting an injection. Unfortunately, many drugs, can’t be given as a pill because they get broken down in the stomach before they can be absorbed. To help overcome that obstacle, researchers have devised a novel drug capsule coated with tiny needles that can inject drugs directly into the lining of the stomach after swallowed.
Federal health officials on Tuesday confirmed the first case of Ebola diagnosed in the U.S., a patient who recently traveled from Liberia to Dallas and a sign of the far-reaching impact of the out-of-control epidemic in West Africa. The unidentified patient was critically ill and has been in isolation at Texas Health Presbyterian Hospital since Sunday, officials said.
Researchers at the Univ. of Michigan have described a new approach to discovering potential cancer treatments that requires a fraction of the time needed for more traditional methods. They used the platform to identify a novel antibody that is undergoing further investigation as a potential treatment for breast, ovarian and other cancers.
Over the past few years, a class of compounds called ADEPs (cyclic acyldepsipeptides) has emerged as a promising new weapon in the fight against drug-resistant bacteria. The compounds work by attaching themselves to a cellular enzyme called ClpP, which bacterial cells use to rid themselves of harmful proteins. With an ADEP attached, ClpP can’t function properly, and the bacterial cell dies.
Univ. of California, Santa Barbara’s Paul Atzberger, a professor in the Department of Mathematics and in mechanical engineering, often works in areas where mathematics plays an ever more important role in the discovery and development of new ideas. Most recently he has developed new mathematical approaches to gain insights into how proteins move around within lipid bilayer membranes.
Microbes have an amazing ability to feed on plant biomass and convert it into other chemical products. Tapping into this talent has the potential to revolutionize energy, medicine, environmental remediation and many other fields. The success of this effort hinges in part on metagenomics, the emerging technology that enables researchers to read all the individual genomes of a sample microbial community at once.
A mysterious space within a protein critical to photosynthesis is filled with fat molecules that influence both the protein’s architecture and electrical properties, according to two recent studies. Researchers studied the atomic structure of, and electrical interactions within, the cytochrome bf complex, a protein complex central to the transport of electrons within membranes of a plant cell, a critical step in photosynthesis.
Massachusetts Institute of Technology engineers have devised a way to rapidly test hundreds of different drug-delivery vehicles in living animals, making it easier to discover promising new ways to deliver a class of drugs called biologics, which includes antibodies, peptides, RNA and DNA, to human patients.
The 2nd Annual Pharma Data Analytics Conference will enable senior-level analytics professionals to improve the bottom line of their business through utilizing the potential of big data. Driven by single-track case study presentations from Pfizer, Celgene, Novartis, Merck and many others, this program will explore recent trends in the pharmaceutical environment, including the influence of analytics in the commercial space, data visualization tools and techniques and methodologies for forecasting across multiple business units.
How the brain ages is still largely an open question because this organ is mostly insulated from direct contact with other systems in the body. In recent research, scientists in Israel found evidence of a unique “signature” that may be the “missing link” between cognitive decline and aging. The scientists believe that this discovery may lead, in the future, to treatments that can slow or reverse cognitive decline in older people.
Years before they show any other signs of disease, pancreatic cancer patients have very high levels of certain amino acids in their bloodstream, according to a new study. This finding, which suggests that muscle tissue is broken down in the disease’s earliest stages, could offer new insights into developing early diagnostics for pancreatic cancer, which kills about 40,000 Americans every year.
An Oak Ridge National Laboratory team has unlocked the enzymatic synthesis process of rare sugars, which are useful in developing drugs with low side effects. In a recently published paper, the team reported the pioneering use of neutron and x-ray crystallography and HPC to study how the enzyme D-xylose isomerase, or XI, can cause a biochemical reaction in natural sugar to produce rare sugars.
Cryptophytes, complex single-cell algae that make up a lot of the ocean's phytoplankton, have, in the course of evolution, adapted their light-harvesting mechanisms to their environment and have thus become capable of utilizing green light. Researchers in Germany have recently been the first ones to reveal similarities and differences in the assembly of this light-harvesting machinery compared to cyanobacteria and red algae.
Almost all of today’s previously existing cell-sorting methods rely on what is called a single-cell analysis platform. A researcher in Hawaii took a different approach, inventing a bulk method that sorts different cell populations by tuning their solubility. Instead of targeting individual features, the measurement principle sorts cells by differentiating their characteristic surface free energies.
Chemists in the U.K. have gained fresh insights into how a disease-causing enzyme makes changes to proteins and how it can be stopped. The scientists hope their findings will help them to design drugs that could target the enzyme, known as N-myristoyltransferase (NMT), and potentially lead to new treatments for cancer and inflammatory conditions.
Researchers may soon have a better idea of how tiny particles of pollution are formed in the atmosphere. These particles, called aerosols, are hazardous to human health and contribute to climate change, but researchers know little about how their properties are shaped by chemical reactions in the atmosphere. Unraveling this chemistry could someday lead to more effective policies to protect human health and the Earth’s climate.
One of the big frustrations of surgery is that little indicates whether the patient is a fast or slow healer, someone who feels normal in a week or is out of work for a month with lingering pain and fatigue. Now Stanford Univ. researchers have discovered that right after surgery, patients' blood harbors clues about how fast they'll bounce back. And it has to do with the activity of certain immune cells that play a key role in healing.
A new wearable medical device can quickly alert a person if they are having cardiovascular trouble or if it’s simply time to put on some skin moisturizer, reports a Northwestern Univ. and Univ. of Illinois at Urbana-Champaign study. The small device, approximately five centimeters square, can be placed directly on the skin and worn 24/7 for around-the-clock health monitoring.
Platelets, the tiny cell fragments whose job it is to stop bleeding, are very simple. They don’t have a cell nucleus. But they can “feel” the physical environment around them, researchers at Emory Univ. and Georgia Tech have discovered. Platelets respond to surfaces with greater stiffness by increasing their stickiness, the degree to which they “turn on” other platelets and other components of the clotting system, the researchers found.
Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine, researchers report. Their studyis the first to use biochemical approaches to confirm the hypothesis that microbes in the human gut can digest fiber.
Purdue Univ. researchers have discovered the structure of the enzyme that makes cellulose, a finding that could lead to easier ways of breaking down plant materials to make biofuels and other products and materials. The research also provides the most detailed glimpse to date of the complicated process by which cellulose is produced.
Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of Massachusetts Institute of Technology (MIT) researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.
The liver provides critical functions, such as ridding the body of toxins, but its failure can be deadly, and there are few options for fixing it. A promising alternative in development is transplanting liver cells made using adult stem cells, but the only source identified until now has been bone marrow. Recently, scientists identified another, more convenient, source of adult stem cells that could be used for this purpose:tonsils.
