Lower calorie intake by host may increase chances of surviving malaria

The chances of surviving a malaria infection may be higher when the host consumes fewer calories, according to new research.

EPO blood doping has little effect on amateur cyclists’ road race performance

According to a new study published in The Lancet Haematology, recombinant human erythropoietin (rHuEPO), a performance augmenting drug has little effects on high-intensity laboratory cycling test among well-trained amateur cyclists; yet in the laboratory time trial test and endurance road-race up Mont Ventoux (France), the augmenting effects were typically undetectable.

Lipoprotein abnormalities linked to vaso-occlusive events in patients with sickle cell disease

An article published in Experimental Biology and Medicine (Volume 242, Issue 12, June, 2017) links imbalances in lipoprotein metabolism with vaso-occlusive events in patients with sickle cell disease

Traditional treatment can more effectively treat iron-deficiency anemia, clinical trial shows

Although current treatments for iron-deficiency anemia can be effective, they commonly fail because pediatric patients do not complete the treatment and might experience adverse effects related to using high doses.

New cancer drug shows promise to treat leukemia in mouse models

Almost 6,000 new cases of acute lymphoblastic leukemia, or ALL, are expected to be diagnosed this year in the United States. The blood cancer can affect both children and adults.

LMU researchers show how genetic variant in people of African ancestry modulates immune cells

A genetic variant that is particularly prevalent in people of African ancestry confers protection against malaria. LMU researchers have now shown how it modulates the properties of white blood cells that play a major role in immune defenses and inflammation.

Researchers discover new anti-thrombotic drug target for developing more protective blood thinners

Blood platelets shore up open wounds and help cuts heal, but they can also cause heart attacks and strokes when a congealed ball of platelets known as a thrombus breaks free from a site of injury and gets lodged in blood vessels that feed oxygen to the brain or heart.

Researchers show how DPF2 protein controls blood cell production in leukemia

Many things go wrong in cells during the development of cancer. At the heart of the chaos are often genetic switches that control the production of new cells.

Complex malaria vaccine protects monkeys against virulent parasite strains

Researchers from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, modified an experimental malaria vaccine and showed that it completely protected four of eight monkeys that received it against challenge with the virulent Plasmodium falciparum malaria parasite.

Researchers discover innovative way to produce hematopoietic stem cells

A study published on May 17 in Nature, discovers an innovative method to produce infinite supply of healthy blood cells from the readily available cells that line blood vessels. This achievement by the researchers at Weill Cornell Medicine marks the first time that any research group has generated such blood-forming stem cells.

New study explores safety of exercise in children with sickle cell disease

While regular exercise is known to reduce inflammation over time, it actually increases inflammation in the short term.

Contrary behavior by blood vessels in the brainstem is what keeps us breathing, research suggests

Certain blood vessels in the brainstem constrict when blood vessels elsewhere in the body would dilate. And that contrary behavior is what keeps us breathing, according to a new paper by UConn researchers published May 8 in eLife.

Astronauts' exercise capacity goes down during spaceflight due to decreased blood vessel function

Astronauts aboard the International Space Station have decreased physical fitness because of a decrease in the way oxygen moves through the body, according to a Kansas State University kinesiology study.

New technique uses modified insulin and red blood cells to reduce blood sugar levels

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a new technique that uses modified insulin and red blood cells to create a glucose-responsive "smart" insulin delivery system.

Dendritic cells develop from specialized progenitors, research shows

Dendritic cells are gatekeepers of Immunity and are crucial for the detection and initiation of Immunity against pathogens and foreign substances. Up to now dendritic cell subtypes were thought to develop from one common progenitor.

Researchers develop hybrid nanomaterial for destruction of cancer cells

Most tumors contain regions of low oxygen concentration where cancer therapies based on the action of reactive oxygen species are ineffective.

Research offers new way to improve nanopharmaceuticals for personalized medicine

In a newly published study in Nature Nanotechnology, the shape and geometry of nanoparticles can have a significant impact in modulating adverse injection reactions and offer realistic solutions for patients receiving nanopharmaceuticals—drug delivery systems specializing in microscopic-particle drug combinations.

Engineered nanosponges can reduce severity of infections caused by group A Streptococcus

In a new study, researchers show that engineered nanosponges that are encapsulated in the membranes of red blood cells can reduce the severity of infections caused by group A Streptococcus, the bacteria responsible for strep throat and life-threatening infections such as necrotizing fasciitis, or flesh-eating disease.

Medical complications of brown recluse spider bites can be severe in children

Medical complications of brown recluse spider bites are uncommon but they can be severe, particularly in children, researchers at Vanderbilt University Medical Center reported today.
