Fragments of erythrocyte membranes are not only able to stop the bleeding, but also are able to prevent the spread of thrombosis
Red blood cells (RBCs), also called erythrocytes, are the most common type of blood cell and principal means of delivering oxygen to body tissues. Human erythrocytes develop from stem cells into mature erythrocytes in about 7 days. When matured, in a healthy individual these
Kidney angiotensinogen as a cardinal risk factor in hypertension
High blood pressure is prevalent in over 30% of the adult population and accounts for approximately one fourth of patients with heart failure, especially the elderly. The renin-angiotensin system (RAS) is of critical importance in the regulation
AntiVEGF therapy: hidden changes on heart and vessels
VEGF (Vascular endothelial growth factor) is a protein normally present in our organism that promotes the growth of new blood vessels, a process known as angiogenesis. Cancer cells produce this substance in large quantity, obtaining a continuous
Drinking tea lowers blood pressure
High blood pressure is a common condition in which the chronic force of the blood to the walls of the arteries may eventually cause health problems. According to the World Health Organization, high blood pressure causes almost
Plant flavonoids prevent cancer progression through suppression of new blood vessel formation
Flavonoids are a sub-family of polyphenolic compounds. They are abundantly found in plants and known to have inhibitory properties in the initiation, promotion and progression of invasive cancers. Cancer progression is a complex process. It is mainly
Albuminuria and cognitive decline
People with type 2 diabetes (T2DM) have a 50-100% increased risk of developing cognitive decline and dementia as compared to people without T2DM. The reasons for this decline are not yet clearly defined but are likely to
Epstein–Barr virus in peripheral blood predicts response to rituximab therapy in rheumatoid arthritis
Rheumatoid arthritis (RA) is an autoimmune disease, characterized by chronic inflammation of the joints that may cause permanent cartilage and bone damage. The cause of RA is unknown. It is, however, believed that a combination of genes
What does the PROMISE trial mean for cardiac CT?
Current guidelines recommend functional testing (FT) such as exercise tests or nuclear tests (with very high radiation exposures) to identify those patients who have chest pain that may benefit from stents or bypass surgery. Unfortunately, a vast
Tricking the body into building new heart valves and blood vessels
When heart valves or small blood vessels fail, surgically implanting a replacement can be a life-saving operation. Right now, replacement blood vessels are harvested from the patient’s leg or chest, which is an additional invasive procedure. Heart
Human blood brain barriers malfunction in Alzheimer’s disease
While the ancient Greeks and Romans already associated old age with dementia, it was not until 1901 that the German psychiatrist Alois Alzheimer diagnosed the first case of Alzheimer’s disease in a fifty year old woman. Today,
Leukemia cells rely on vesicles from neighboring stromal cells to resist common cancer treatments
Leukemia is a cancer of white blood cells that occurs in both children and adults. Strides have been made in curing most types of leukemia. However, acute myeloid leukemia (AML) continues to resist the same treatment strategies.
CD64 as a sepsis marker
Sepsis is the most common cause of mortality in critically ill patients worldwide. Despite with huge costs, it is difficult to treat sepsis. Early diagnosis sepsis and timely treatment are vital to improving outcomes and lightening the
Oxygen-transfer performance of a new, very low-volume membrane oxygenator
During heart surgery, an external system (extracorporeal circulation) is often needed to replace the normal function of the heart and lungs to ensure blood circulation to the brain and all other organs. One key element of this
Utilizing inkjet printing for low-cost glucose monitoring
Diabetes is a disease affecting more and more people across the world every year. In low-income countries, this growth is most detrimental since they lack the healthcare infrastructure necessary to deal the growing problem. Work is being
A simple way to measure health of the autonomic nervous system
The autonomic nervous system (ANS) unconsciously regulates the function of internal organs, including the heart. A poorly functioning ANS has been linked to a number of cardiovascular complications, including hypertension and stroke. Thus, simple tests of ANS
Heated red blood cells shed vesicles to indicate distress
When a human or animal are exposed to elevated temperature, the body temperature rises. A small increase in the body temperature may result in health problems that include a headache, dizziness, or fainting. Red blood cells are
Caged hens with unusual white blood cells
Animal welfare and egg supply sustainability issues are now top priorities. Currently, most eggs are from caged hens whose welfare is a question. To address the issue, microscopic data from blood counts of hens in three cage
The development of a new blood substitute
The first transfusion ever performed is generally attributed to James Blundell in the beginning of the eighteenth century. Since Blundell’s experiments until the beginning of the twentieth century, transfusion was considered an extremely risked procedure with general
Sugars in circulating blood reflect breast cancer biology
In our studies, consisting of measurements and analyses, we have shown that the sugar composition in the serum of breast cancer patients reflects the biology of their breast tumours. Patients with different kinds of breast tumours have
