Hurricane Sandy's lesser-known victims: Lab rats
The New York Times
Share
  
Among the smaller but still important casualties of Hurricane Sandy were thousands of laboratory rodents, genetically altered for use in the study of heart disease, cancer and mental disorders like autism and schizophrenia, that drowned in basement rooms at a New York University research center in Kips Bay. The collection of carefully bred rodents was considered one of the largest and most valuable of its kind in the country.

Infectious disease, pollution concerns arise from Sandy aftermath
The Disease Daily
Share
  
Hurricane Sandy's wrath has only just ended and the extensive destruction felt by millions of families along the East Coast is slowly being put into perspective. However, sewage is only part of the problem. Public health and environmental officials have raised concerns about contamination from toxic industrial waste.

Climate can be used to predict outbreaks
The Associated Press via Laboratory Equipment
Share
  
Two United Nations agencies have mapped the intersection of health and climate in an age of global warming, showing that there are spikes in meningitis when dust storms hit and outbreaks of dengue fever when hard rains come. Officials say that their "Atlas of Health and Climate" is meant to be a tool for leaders to use to get early warning of disease outbreaks.

Researchers 'watch' antibiotics attack tuberculosis bacteria inside cells
Weill Cornell Medical College via Infection Control Today
Share
  
Weill Cornell Medical College researchers report that mass spectrometry, a tool currently used to detect and measure proteins and lipids, can also now allow biologists to "see" for the first time exactly how drugs work inside living cells to kill infectious microbes. As a result, scientists may be able to improve existing antibiotics and design new, smarter ones to fight deadly infections, such as tuberculosis.

Meningitis outbreak spreads to 19 states with case in Rhode Island
Reuters via Medscape Medical News
Share
  
The deadly meningitis outbreak tied to steroid injections from potentially tainted medications spread to a 19th state with the first case reported in Rhode Island, the Centers for Disease Control and Prevention said. Only four of the 23 states that received some of the medication have not reported cases of fungal meningitis, which has killed 25 people nationwide.

Watching the cogwheels of the biological clock in living cells
University of Geneva via PhysOrg
Share
  
Our master circadian clock resides in a small group of about 10,000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group of Ueli Schibler, professor at the Department of Molecular Biology of the University of Geneva, Switzerland. The molecular mechanisms of circadian clocks can thus be studied outside of the animals, in cultured cells.

Influenza rapid tests show variable performance
Medscape Medical News
Share
  
A study evaluating the performance of 11 U.S. Food and Drug Administration–cleared rapid influenza diagnostic tests in 23 recently circulating influenza viruses showed that lower concentrations of influenza virus types and subtypes are differentially detected by these tests. According to the researchers, commercially available RIDTs are widely used in clinical practice to diagnose influenza because of their simplicity and rapid detection (within 15 minutes) of the influenza virus nucleoprotein antigen. However, these tests have not been analyzed in a standardized laboratory setting against a panel of representative seasonal influenza viruses.

Fighting the spread of viruses: Producing cheap vaccines, quickly
University of Queensland via Medical Xpress
Share
  
Immunizing people with vaccines that are quick and inexpensive to produce is the answer to preventing large-scale spread of infectious disease, Professor Anton Middelberg from the University of Queenland's Australian Institute for Bioengineering and Nanotechnology says. Using modern molecular and bioprocessing tools, Middelberg and his team are developing vaccines that can be changed and manufactured for the entire Australian population within days of a new virus appearing.

Pediatricians OK embryonic stem cell research
MedPage Today
Share
  
Citing its potential for use in pediatric diseases, the American Academy of Pediatrics has thrown its support behind human embryonic stem cell research. The research has possible implications for certain childhood diseases, including hypoxic-ischemic encephalopathy, bone marrow failure syndromes, leukemia, congenital heart disease, neonatal lung disease and Type 1 diabetes, according to members of the academy's committees on pediatric research and bioethics.

Doctors can regrow breast tissue after surgery
The Age
Share
  
Melbourne, Australia, surgeons have partially succeeded in regrowing breast tissue using a patient's own fat cells in 1 of 5 women involved in a pilot trial after cancer surgery. Surgeons implanted each woman with an acrylic breast-shaped chamber, into which they redirected blood vessels attached with the patient's fat cells from under her arm. The technique, called Neopec, has been tested on five women over the past 18 months in the hope it could help them regrow breasts after a mastectomy, as an alternative to silicone implants.

New procedure for bone tissue replacement
Simon Fraser University via Medical Xpress
Share
  
A Simon Fraser University technology MBA graduate has developed a new procedure for bone tissue engineering and plans to use his newfound business acumen to take the research to the next level. Andre Wirthmann's research aims to benefit patients with bone defects who would normally require a conventional bone augmentation procedure. The process takes a small sample of the patient's tissue and grows it into a larger piece of bone, which is then implanted back into the patient.
