Fat stem cells being studied as option for breast reconstruction

...dy is shaped into the form of a breast. Neither is ideal nor without risk. The use of adipose- or fat-derived stem cells may represent a better solution for soft tissue reconstruction in breast cancer patients," said Dr. Rubin, who also is co-director of the Aesthetic Surgery Center at the University of Pi...

A transplant in time

...mophilic patients. Thus, the scientists fixed the ideal time for spleen transplantation at 42 days. Hemophiliac mice with spleen tissue transplanted from pig embryos at this time experienced completely normal blood clotting within a month or two of implantation. Although a number of problems would ne...

Living laboratory found on shoreline statues

...urface of the sculptures has provided them with an ideal habitat for settlement as well as offering scientists an important insight into factors influencing colonisation. The installation of the cast iron figures - each a replica of the artist's own body, and identical in size, shape and material - of...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...rk that may lead to the development of trees as an ideal "feedstock" for a new generation of biofuels such as cellulosic ethanol. The research is the result of a four-year scientific and technical effort, led by the U.S. Department of Energy's Joint Genome Institute (DOE JGI) and Oak Ridge National Laborat...

Nerve cell software keeps track of brain change

...,000 delegates expected, the conference will be an ideal focus for the software's international launch. Dr Pascal Vallotton, Leader of Biotech Imaging at CSIRO Mathematical and Information Sciences, says there are few images more complex than the intricate, web-like branches of nerve cells photographed d...

Ferns provide model for tiny motors powered by evaporation

MIT's molecular sieve advances protein research

...tly. "This device can replace gels and give us an ideal physical platform to investigate Ogston sieving," Fu said. The new sieves also potentially could be used to replace 2D gels in the process of discovering disease biomarkers, as well as to learn more about disease. ...

Researchers link ocean organisms with increased cloud cover and potential climate change

...ge of a couple of watts." The Southern Ocean is ideal for study because it is largely untouched by pollution and has relatively steady temperature and meteorological conditions during the seasons in which phytoplankton blooms appear. "This seems to be one of those rare regions in the globe where the bi...

Edible coatings will be the packaging of the future

...glycerol did not alter their composition. Once the ideal plastifier for the coating was determined, it was observed that, in order to improve malleability, it was necessary to introduce a lot of glycerol. However, using high quantities of plastifier in a coating results in an increase in its permeability t...

Cholera pathogen reveals how bacteria generate energy to live

...nction, but enzymes that work with sodium ions are ideal for experimental study, according to Barquera. Sodium is easier to trace and its concentration can be changed without affecting pH, which is a complication with protons. "It’s a very good system to understand this very basic mechanism charging this b...

'Exercise pill' switches on gene that tells cells to burn fat

.... Evans. In today’s society, too few people get an ideal amount of exercise, some because of medical problems or excess weight that makes exercise difficult. Having access to an "exercise pill" would improve the quality of muscles, since muscles like to be exercised, and increase the burning of energy or e...

Clues to gene expression in cystic fibrosis will guide research

...ts?respiration. Gentamicin itself may not be an ideal drug option, as it may cause serious side effects for some patients, including ear and kidney damage. The authors suggest that other drugs, such as amikacin or PTC124, with a comparable mode of action and fewer side effects, may have treatment potent...

Cryoablation -- A new treatment option for some kidney tumor patients

... minimal." He cautions that this procedure is not ideal for everyone, noting that it is an option for only a relatively small subset of patients. Percutaneous ablation uses needles to penetrate the skin and deliver directly to the tumor either high-intensity, tissue-destroying heat through radiofrequen...

Study of planarians offers insight into germ cell development

...out, the tiny, seemingly cross-eyed flatworm is an ideal subject for the study of germ cells, precursors of eggs and sperm in all sexually reproducing species. The planarian Newmark studies, Schmidtea mediterranea, is a tiny creature with a lot of interesting traits. Cut it in two (lengthwise or crosswi...

Ethanol vehicles pose a significant risk to human health, study finds

...about 6 percent of the U.S. population, it is also ideal for a more detailed study,'' he wrote. Jacobson programmed the computer to run air quality simulations comparing two future scenarios: A vehicle fleet (that is, all cars, trucks, motorcycles, etc., in the United States) fueled by gasoline, ver...

New research says winning a Nobel Prize adds nearly 2 years to your lifespan

...ften brings. Nobel Prize winners were viewed as an ideal group to study as the winners could be seen as having their status suddenly dropped on them. They also come with a ready made control group they can be directly measured against - scientists who were nominated for a Nobel prize but did not actually w...
