New discovery may soon make prostate cancer cells easier to destroy

A newly discovered connection between two common prostate cancer treatments may soon make prostate cancer cells easier to destroy. Drugs that could capitalize on the discovery are already in the pipeline, and a clinical trial to test whether the finding could improve treatments for prostate cancer patients could be only a few years away.

New nanotechnology approach could transform gliomas from death sentence into treatable condition

An MRI contrast agent that can pass through the blood-brain barrier will allow doctors to detect deadly brain tumors called gliomas earlier, say Penn State College of Medicine researchers. This ability opens the door to make this fatal cancer treatable.

Candidiasis needs to be treated early, aggressively to help vulnerable hospitalized patients

One of the most common causes of healthcare-associated infections, candidiasis is a serious, life-threatening fungal infection that needs to be treated early, aggressively and appropriately, note updated guidelines released by the Infectious Diseases Society of America and published in the journal Clinical Infectious Diseases.

A glass of clean drinking water contains 10 million bacteria

Researchers from Lund University in Sweden have discovered that our drinking water is to a large extent purified by millions of "good bacteria" found in water pipes and purification plants. So far, the knowledge about them has been practically non-existent, but this new research is about to change that.

UMMS researchers identify new life cycle stage in HIV infection

Researchers at the University of Massachusetts Medical School have identified a new life cycle stage in HIV infection, thanks to a novel technique they developed to take images of intact infected cells.

Treated greywater does not pose risk for water-related diseases

Researchers at the Zuckerberg Institute for Water Research at Ben-Gurion University of the Negev have determined that treated greywater is safe for irrigation and does not pose a risk for gastrointestinal illness or water-related diseases.

Researchers identify how immune cells triggered by recurrent Strep A infections affect the brain

Researchers have discovered how immune cells triggered by recurrent Strep A infections enter the brain, causing inflammation that may lead to autoimmune neuropsychiatric disorders in children.

SLU researcher discovered world's first dengue vaccine

A vaccine to prevent dengue fever discovered by a Saint Louis University researcher in 1997 and now licensed worldwide by Sanofi Pasteur has been approved for use in Mexico. Dengvaxia is the world's first vaccine approved to prevent dengue fever, which is a virus spread by mosquitoes primarily in tropical and sub-tropical areas.

VCU Massey Cancer Center scientists reveal signaling process that leads to excessive growth of cancer

The gene p53 has been described as the "guardian of the genome" due to its prominent role in preventing genetic mutations. More than half of all cancers are thought to originate from p53 mutations or loss of function, and now a recent study by VCU Massey Cancer Center scientist Richard Moran, Ph.D., explains why.

SLU scientist awarded new $2.2 million NIH grant to develop cure for hepatitis B

With proof-of-principle in his pocket and a new $2.2 million grant from the National Institutes of Health, SLU scientist John Tavis, Ph.D., will take his 25 year mission to finally develop a cure for the hepatitis B virus into the next phase.

Unhealthy microbiome shifts can lead to weight gain, obesity

The link between the gut microbiome and obesity seems clear, but just how changes to gut bacteria can cause weight gain is not.

Study: Brain cell death may trigger multiple sclerosis

Multiple sclerosis (MS) may be triggered by the death of brain cells that make myelin, the insulation around nerve fibers, according to research on a novel mouse model developed by scientists from the University of Chicago and Northwestern Medicine. The death of these cells initiates an autoimmune response against myelin, the main characteristic of the disease, which leads to MS-like symptoms in mice.

Mount Sinai scientists develop new tool to determine global role of microRNAs

As microRNA biology has been implicated in everything from the development of cancer to virus infections, a new tool developed by scientists at the Icahn School of Medicine at Mount Sinai holds tremendous potential to develop new therapies that involve these small regulatory fragments of RNA.

Virologists demonstrate how poxviruses defeat the body's host immune defenses

Smallpox virus, which killed millions of humans through the ages, ranks among the world's most feared bioterrorism agents. Human monkeypox continues to occur sporadically in remote African villages.

ESCMID’s EUCAST plays key role in defining antimicrobial resistance in Europe and globally

The European Society of Clinical Microbiology and Infectious Disease (ESCMID) – an organization that pursues science, explores risk assessment, knowledge sharing and best practices in the fight against infectious disease – is currently researching the new critical breakpoints for antimicrobial agents in clinical development through its European Committee on Antimicrobial Susceptibility Testing (EUCAST).

Study reveals how MGCs dispose waste that obstructs normal physiological processes

If rubbish is too big and unwieldy for normal household waste, its removal becomes the job of specialized experts. Researchers from the Technical University of Munich (TUM) have now discovered, in cooperation with colleagues from the UK, how large, fused cells help our body to deal with bulky items that may otherwise obstruct normal physiological processes.

Bacteriophage therapy: an alternative to antibiotics? An interview Professor Clokie

A phage is a virus that infects a bacterium. People often get very confused about what the difference is between a virus and a bacterium. A virus, like a bacterium, is also a microorganism, but unlike bacteria, it needs to have a host to be able to replicate and propagate.
