A single letter difference in a single gene spells a lifetime of anemia, pain worldwide

A single letter difference in a single gene, inherited from both parents, spells a lifetime of anemia and pain for 20 million people, mostly of African ancestry, worldwide.

Cone snail venom could potentially treat severe forms of malaria

Severe forms of malaria such as Plasmodium falciparum may be deadly even after treatment with current parasite-killing drugs.

FDA approves drug to reduce frequency of chemotherapy-induced bone marrow suppression

Today, the U.S. Food and Drug Administration approved Cosela (trilaciclib) as the first therapy in its class to reduce the frequency of chemotherapy-induced bone marrow suppression in adults receiving certain types of chemotherapy for extensive-stage (when the cancer has spread beyond the lungs) small cell lung cancer.

New genetic analysis reveals biological causes of muscle weakness in older people

A new largescale genetic analysis has found biological mechanisms that contribute to making people more susceptible to muscle weakness in later life, finding that diseases such as osteoarthritis and diabetes may play a large role in susceptibility.

Researchers uncover traces of malarial adaptation in African people

Malaria is an ancient scourge, but it's still leaving its mark on the human genome. And now, researchers have uncovered recent traces of adaptation to malaria in the DNA of people from Cabo Verde, an island nation off the African coast.

Certain malaria parasites use a mechanism to cross the blood–brain barrier

Malaria is one of the most common causes of death in children in Africa and is triggered by a small parasite that lives in the blood. When the parasite builds up in the blood vessels of the brain, it develops into one of the most dangerous forms of the disease, cerebral malaria.

Scientists uncover elusive mechanism behind the most severe cases of blood disorder

With a name like glucose-6-phosphate dehydrogenase deficiency, one would think it is a rare and obscure medical condition, but that's far from the truth.

Researchers find potential biomarkers of Parkinson's disease

A research team led by Nagoya University in Japan has found that blood pressure, the hematocrit (the percentage of red blood cells in blood), and serum cholesterol levels change in patients with Parkinson's disease long before the onset of motor symptoms.

Study: Fibroblast hormone promotes movement of hematopoietic stem cells

Discovery expected to contribute towards more effective methods of harvesting stem cells from bone marrow donors.

No inflammation of cerebrospinal fluid in COVID-19 patients with neurological features, study finds

Many patients with COVID-19 have shown neurological complications, leading to scientific interest in the role played by its causative pathogen, SARS-CoV-2, in brain inflammation. A new study has described the absence of neuroinflammation in cerebrospinal fluid (CSF).

New findings could help better understand the mechanisms underlying severe malaria

The levels of small molecules called microRNAs (miRNAs) circulating in blood could help identify early on children with life-threatening forms of malaria, according to a study led by the Barcelona Institute for Global Health, an institution supported by "la Caixa" Foundation, in collaboration with the Manhiça Health Research Center (CISM) in Mozambique.

Higher hemoglobin threshold does not improve outcomes in preterm infants

Very low birthweight infants are at a high risk for anemia and often need blood transfusions to survive. Some doctors use a higher level and some use a lower level of red blood cells to order a transfusion.

The evolving role of platelet-rich plasma in cosmetic procedures

Platelet-rich plasma (PRP) treatment, which involves injecting a small amount of a patient's own blood to release various growth factors from platelets, continues to increase in popularity.

Could engineered red blood cells be an effective antiviral against SARS-CoV-2?

In a new study, released on the bioRxiv* preprint server, a team of researchers explores the antiviral potential of red blood cells against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of COVID-19.

Detailed simulations reveal new information on sickle cell disease

Although there has yet to be a cure for sickle cell disease, researchers recently created detailed simulations on the Comet system at the San Diego Supercomputer Center (SDSC) showing how these stiff red blood cells flow through blood vessels, deforming and colliding along the way.

Experimental stem cell gene therapy may give a new lease of life for patient with sickle cell disease

"But it's a marathon whereas you keep going, the trail gets rockier and then you lose your shoes," the 27-year-old said. "It gets harder as you get older. Things start to fail and all you can think about is how much worse it's going to get down the road."
