Cachexia

Withering Away: How Viral Infection Leads To Cachexia?

Many patients with chronic illnesses such as AIDS, cancer and autoimmune diseases suffer from an additional disease called cachexia. The complex, still poorly understood syndrome, with uncontrollable weight loss; and shrinkage of both fat reserves and muscle tissue; contribute to premature death. Researchers at CeMM Research Center for Molecular Medicine of the Austrian Academy of…

RNA Viruses

The Replication of World’s Deadliest Human RNA Viruses

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material; often making thousands of copies of themselves in a single cell to ensure their replication and survival. Some RNA viruses insert their genetic material as a single piece, while others chop it up into pieces. The latter are aptly named segmented viruses.…

Measles

Three Moral Reasons To Get Children Vaccinated Against Measles

The U.S. hit a terrible and entirely preventable milestone this week: Measles cases are at a 25-year high. This alarming statistic is not due to changes in public health policy or medical practice, but the rise of the anti-vax movement. Researchers who study the beliefs of parents who refuse to have their children vaccinated have found they have both…

Dengvaxia

US Approves Dengue Vaccine Dengvaxia

A virus is a microscopic infectious agent that can reproduce only inside a host cell. Viruses infect all types of organisms: from animals and plants, to bacteria and archaea. Since the initial discovery of tobacco mosaic virus by Martinus Beijerinck in 1898; more than 5,000 types of virus have been describing in detail, although most types…

Herpes

The Line Between Different Recombinant Versions Of Herpes

The line between the human herpes simplex viruses—HSV-1 and HSV-2—is blurrier than previously thought, according to a new study published this week in the Journal of Infectious Diseases. Researchers found that HSV-1 and HSV-2 are mixing together to result in several new, different recombinant versions of herpes. “The main implication is that HSV-1 and HSV-2 are…

Herpes Virus

Humanization of Antibodies Targeting Human Herpes Virus 6B

A research group led by Professor Yasuko Mori (Division of Clinical Virology, Center for Infectious Diseases; Kobe University) has succeeded in humanization of mouse antibodies; that can neutralize the infection caused by human herpesvirus 6B (HHV-6B). Infection by HHV-6B in infants can lead to complications such as encephalitis—brain inflammation; but an effective way to control…

Flu

New Techniques Could Protect From Flu For Lifetime

A new approach that teaches the body to recognize the cone portion of the virus; but which stays the same year-to-year; could shake up that yearly vaccination ritual and protect people against pandemic flu; like the one that killed 40 to 50 million people in 1918. The team working on this new approach, led by…

Fentanyl Addiction

Vaccine Shows Lasting Effects Against Fentanyl Addiction In Rats

A vaccine that combines a fentanyl antigen with a tetanus toxoid; was showing to reduce fentanyl choices and increase food choices with effects lasting several months in rats. But these results suggest that the vaccine may not only decrease dangerous drug-taking behavior; but can also increase behaviors maintained by healthier non-drug alternatives. The findings are…

Viruses Impacts Susceptibility To Future Infections

The findings, published in eLife, help to address a fundamental question in infectious disease biology: why are some individuals genetically resistant to infection; while others are genetically susceptible? Answering this question has potential implications for reducing disease, for example where genetic variation plays a role in a mosquito’s ability to transmit malaria. “Whether you look at humans…

Vaccine Injury

Governments Urged To Adopt Compensation For Rare Vaccine Injury

Research led by The University of Western Australia has found that that most countries with mandatory childhood vaccination; policies don’t have no-fault vaccine injury compensation schemes to care for rare victims of vaccines. Lead researcher Katie Attwell, from UWA’s School of Social Sciences; said no-fault compensation schemes enabled governments to address unintended consequences of vaccination.…

Virus Might Cause Paralyzing Condition In Children

A virus appears to be the cause behind a rash of polio-like illnesses that struck Minnesota; and other states last fall, causing paralyzing symptoms in several children; but including one girl who lost all motor function and remains hospitalized. Researchers from Minnesota and the U.S. Centers for Disease Control and Prevention reported Thursday that they…

Human papillomavirus

Evidence Grows For An HPV-Heart Disease Connection

Human papillomavirus, or HPV, is the most common sexually transmitted infection in the country. In several studies, it’s also linked to the nation’s leading cause of death cardiovascular disease. There are more than 150 strains of HPV, including the ones responsible for cancers of the cervix; penis, anus and the back of the throat. In…
