The baroreceptor reflex is a fascinating medical phenomenon. The reflex is controlled by specialized neurons that react in just a fraction of a second to keep blood pressure fairly consistent. For example, when you stand up, your blood pressure normally drops—rapidly. Yet you don't faint thanks to baroreceptors, which tell your heart rate to increase and push more blood to your brain. A new…
Nanosystems that deliver anticancer drugs or imaging materials to tumours are showing significant progress, particularly those that respond to tumour-related stimuli, according to a review published in the journal Science and Technology of Advanced Materials. However, further research is still required to make sure these delivery systems are stable, non-toxic and biodegradable. Nanocarriers…
The complex structure of breast tumours makes treatment a medical challenge. A promising, novel selenium-based breast cancer nanoparticle therapy by the Austrian Centre of Industrial Biotechnology (acib) together with other partners in the EU-project Neosetac could change that: It has proved to boost the active agent delivery and assure it's active only in the target tissue while also bringing…
How is the activity of all genes in cells of higher organisms interconnected? And how are the genetic "wiring diagrams" of the cells in complex tissues coordinated with each other? Scientists from the German Cancer Research Center (DKFZ), the European Molecular Biology Laboratory and the University of Heidelberg are now planning to investigate this in two model organisms, Drosophila and…
Chronic stress is a well-known risk factor for the development of psychiatric illnesses including depression disorders. The brain requires a great deal of glucose, and stress is known to alter glucose metabolism. However, if stress-associated mental impairments are linked to affected glucose metabolism remains to be seen. Researchers at the Department for Psychiatry and Psychotherapy at the Mainz…
Researchers at McMaster University have solved a vexing problem by engineering surface coatings that can repel everything, such as bacteria, viruses and living cells, but can be modified to permit beneficial exceptions. The discovery holds significant promise for medical and other applications, making it possible for implants such as vascular grafts, replacement heart valves and artificial joints…
A research team led by the University of Alabama at Birmingham is launching a study to find a better model for glioblastoma, a particularly devastating type of brain tumour, to help determine the most appropriate treatment modality. The $3.6 million, five-year U01 grant award is funded by the National Cancer Institute, one of the National Institutes of Health. The UAB team will join four other…
Nearly two-thirds of all cancer patients in the United States will undergo radiation therapy as part of their treatment, and as many as 90 percent of those patients will experience radiation dermatitis – a rash or burn on the skin. Topical treatments commonly such as silver sulfadiazine cream contain heavy metals. Therefore, patients have historically been advised to avoid using these…
Men with diabetes are 2.4 times more likely than non-diabetics to suffer heart failure and women are five times more likely. But why? A new Loyola University Chicago Stritch School of Medicine study reveals how, on a cellular level, diabetes can cause heart failure. The findings could lead to medications to treat and perhaps prevent heart failure in diabetes patients, researchers said. In a…
To simulate the blood circulation and the organs of animals or humans, engineers from Fraunhofer in Dresden have developed a so-called "multi-organ chip". This microsystem from the Fraunhofer Institute for Material and Beam Technology IWS Dresden has now received an "EARTO Innovation Award" in Brussels. The "lab-on-a-chip" will help industry to develop new drugs and…
The most common form of Mycobacterium tuberculosis (TB) originated in Europe and spread to Asia, Africa and the Americas with European explorers and colonialists, reveals a new study led by UCL and the Norwegian Institute of Public Health.
The first successful surgery under anaesthesia occurred in the 1840s. Since then, people have been developing theories about what might be going on in the brain while a person is unconscious. Even after thousands of surgeries, researchers still don’t understand exactly which specific areas of the brain are responsible for transitioning into unconsciousness and back.
Cancer experts warn that Brexit will seriously harm UK cancer research and could trigger a manpower crisis that will negatively affect the health of our citizens.
Scientists have uncovered the cause of Saul-Wilson syndrome: A single, spontaneous gene change alters protein packaging in the cell’s Golgi complex, causing the disease.
It has been known for some time that it is better to transfer a single embryo to a woman’s womb during assisted reproduction treatment (ART) to avoid a multiple pregnancy. However, even when single embryo transfer (SET) is performed, some women still become pregnant with twins or even triplets. Researchers have investigated one of the reasons why this happens.
An interdisciplinary and international research group led by Dr. Volker Busskamp from the Center for Regenerative Therapies Dresden at the TU Dresden (CRTD) has decoded the regulatory impact on neuronal survival of a small non-coding RNA molecule, so-called miRNA, at the highest resolution to date.
Women diagnosed with non-small cell lung cancers (NSCLC) live longer than their male counterparts, according to results of a SWOG study presented by Loyola Medicine researcher Kathy Albain, MD, at the International Association for the Study of Lung Cancer's 19th World Conference on Lung Cancer in Toronto.
A commonly used biomarker of kidney disease may also indicate lung problems, particularly COPD, or chronic obstructive pulmonary disease, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Albuminuria, Lung Function Decline, and Risk of Incident COPD: the NHLBI Pooled Cohorts Study,” Elizabeth C.…
Autoimmune diseases like Bechterew’s disease direct our immune systems agains our own bodies. Now, researchers at Jacobs University Bremen have come one step closer to understanding the molecular mechanisms of the disease also known as ankylosing spondylitis. It is characterized by long-term painful inflammation of the joints and deformation of the spine. One suspected cause is a particular…
Researchers at the University of Cambridge and the University of Oxford have discovered a new molecule that plays a key role in the immune response that is triggered by influenza infections.
Historical bias is a key reason why biomedical researchers continue to study the same 10 percent of all human genes while ignoring many genes known to play roles in disease, according to a study led by Thomas Stoeger and Luís Amaral of Northwestern University, and colleagues. This bias is bolstered by research funding mechanisms and social forces.
Scientists working to bioengineer the entire human gastrointestinal system in a laboratory now report using pluripotent stem cells to grow human esophageal organoids.
With new immunotherapy treatments for melanoma, recovery rates have risen dramatically – in some cases to around 50%. But they could be much higher. A new study led by researchers at the Weizmann Institute of Science showed, in lab dishes and animal studies, that a highly personalized approach could help the immune cells improve their ability to recognize the cancer and kill it.
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.
Evidence of tiny particles of carbon, typically created by burning fossil fuels, has been found in placentas for the first time, in new research presented at the European Respiratory Society International Congress. Previous research has indicated links between pregnant mothers’ exposure to air pollution and premature birth, low birth weight, infant mortality and childhood respiratory problems.
