Combatting viral and bacterial lung infections with volatile anesthetics: an interview with Dr Chakravarthy

Inhaled anesthetics are fairly common all over the world for minor and extensive surgical procedures in patients of all age groups. In the olden days when anesthesia was first developed, ether was the first inhaled anesthetic. That has been replaced, with the more recent discoveries of sevoflurane, isoflurane, and desflurane.

Taking steps to prevent, protect against flu

With flu season approaching, parents may be bracing for an outbreak at their children's schools, but adults are also highly susceptible at work and in other public places. Now is the time for families and businesses to take steps to prevent and protect against the flu.

CDC publishes reports on infectious and noninfectious diseases

Beginning with the Oct. 23, 2015, Supplements to Morbidity and Mortality Weekly Report (MMWR), CDC will publish the summaries of all notifiable conditions – infectious and noninfectious – at the same time.

First-ever genomic study shows dengue may survive year-round in southern China

The first-ever comprehensive genomic analysis of the virus that causes dengue fever suggests that it may survive year-round in southern China.

NIH researchers discover why certain immune responses can be harmful to the brain

National Institutes of Health scientists studying inflammation of the brain have discovered why certain immune responses, which typically help cells recognize and fight viral and bacterial infections, can sometimes be harmful to the brain. Many brain disorders involve the death of neurons, or nerve cells, but how these neurons die is not well understood.

Understanding HCV disease progression rates among PWID

The Hepatitis C virus (HCV) infection is a chronic blood-borne viral infection that affects an estimated 160 million people, or 2-3% of the population world-wide. Alarmingly, chronic HCV infection accounts for one-quarter of the cases of cirrhosis and hepatocellular carcinoma (HCC). If HCV is left untreated, chronic liver disease will occur in 60-70% of the cases, cirrhosis in 5-20% of the cases, and 1-5% will die from decompensated cirrhosis or HCC.

Novel portable device counts white blood cells in real time

A novel way to count white blood cells without a blood test, simply by applying a small device on the fingertip, is being developed by a team of young bioengineers. The technology, that combines an optical sensor with algorithms, has already three prototypes on the go and is specially designed to be used on chemotherapy patients, who could know their immune system levels in real time. It could also serve to detect serious infections.

Researchers reveal potential new treatment methods for fatal brain disease

Researchers from the University of Zurich and the University Hospital Zurich reveal possible new treatment methods for a rare, usually fatal brain disease. Thanks to their discovery that specific antibodies play a key role in combating the viral infection, a vaccine against the disease "progressive multifocal leukoencephalopathy" could now be developed.

Novel mechanism may help explain the virulence of 1918 'Spanish' flu

While yearly outbreaks of flu kill about 250,000 to 500,000 people worldwide, the 1918 "Spanish" flu infected one-third of the world's population and killed 50 million to 100 million. Chad Petit, Ph.D., assistant professor in the University of Alabama at Birmingham Department of Biochemistry and Molecular Genetics, has discovered a novel mechanism for one 1918 flu virus protein that may help explain the virulence of that unusually deadly pandemic.

Protein-based modular system could help detect viral infection or kill cancer cells

MIT biological engineers have developed a modular system of proteins that can detect a particular DNA sequence in a cell and then trigger a specific response, such as cell death.

University of Bonn researchers find how cells in the body can detect genetic material of retroviruses

Researchers at the University of Bonn have discovered how cells in the body can detect the genetic material of so-called retroviruses. The pathogen of the immunodeficiency disease AIDS, the HI-1 virus, also belongs to this group. At the same time, the HI virus appears to circumvent this important defense mechanism.

Inhalation exposure to PM2.5 pollution triggers liver fibrosis

A research team led by Kezhong Zhang, Ph.D., at the Wayne State University School of Medicine's Center for Molecular Medicine and Genetics, has discovered that exposure to air pollution has a direct adverse health effect on the liver and causes liver fibrosis, an illness associated with metabolic disease and liver cancer.

Volatile anesthetics may combat viral and bacterial infections in the lung

In use for more than a century, inhaled anesthetics like nitrous oxide and halothane have made modern surgery possible. Now, in experiments in mice, researchers at Johns Hopkins and elsewhere have added to evidence that certain so-called "volatile" anesthetics -- commonly used during surgeries -- may also possess powerful effects on the immune system that can combat viral and bacterial infections in the lung, including influenza and pneumonia.

Gene therapy restores visual function in mouse model of LCA1

Mice lacking the protein retGC1, which is deficient in humans suffering Leber congenital amaurosis-1 (LCA1), a disorder that causes severe visual impairment beginning in infancy, received gene therapy to replace retGC1 and showed fully restored visual function that persisted for at least 6 months.

Discovery could open up door for cancer research and treatment

Florida State University researchers have taken a big step forward in the fight against cancer with a discovery that could open up the door for new research and treatment options.

Researchers identify new virus that plays role in rare type of liver cancer

More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus.

Discovery could help in development of novel cancer-selective viral therapies

Every organism--from a seedling to a president--must protect its DNA at all costs, but precisely how a cell distinguishes between damage to its own DNA and the foreign DNA of an invading virus has remained a mystery.

Researchers discover new hepatitis A-like virus in seals

Scientists in the Center for Infection and Immunity at Columbia University's Mailman School of Public Health have discovered a new virus in seals that is the closest known relative of the human hepatitis A virus. The finding provides new clues on the emergence of hepatitis A.

Significant divide can exist between patients and physicians about same medical terms

Few things are more stressful than dealing with a sick child. From discussing treatment with a pediatrician to complying with day care policies, a parent must consider many factors when making a decision about their child's health. Now, a recent study from the University of Missouri and the University of Michigan is shedding light on the significant divide that can exist between patients and physicians about the same terminology--especially when it comes to discussing "pink eye," a particular flashpoint in childcare.

Researchers develop two simple tools to assess dehydration severity in children

Dehydration from diarrhea, either from viral infection or cholera, accounts for 10 percent of all child deaths worldwide. Though it's a pervasive problem, there are no clinical guidelines that perform better than chance for assessing dehydration severity. In a new study, a team of researchers report that they statistically derived two simple diagnostic tools with high sensitivity and specificity from the cases of 771 children aged 0 to 5 in Dhaka, Bangladesh.
