Glaucoma, a leading cause of blindness worldwide, most often is diagnosed during a routine eye exam. Over time, elevated pressure inside the eye damages the optic nerve, leading to vision loss. Unfortunately, there’s no way to accurately predict which patients might lose vision most rapidly. Now, studying mice, rats and fluid removed from the eyes of patients with glaucoma, researchers at…
Even in remission, cancer looms. Former cancer patients and their doctors are always on alert for metastatic tumors. Now scientists at The Scripps Research Institute (TSRI) have discovered why some cancers may reoccur after years in remission.
Autonomous driving, automatic speech recognition, and the game Go: Deep Learning is generating more and more public awareness. Scientists at the Helmholtz Zentrum München and their partners at ETH Zurich and the Technical University of Munich (TUM) have now used it to determine the development of hematopoietic stem cells in advance. In ‘Nature Methods’ they describe how their software…
Doctors have found a way to manipulate wounds to heal as regenerated skin rather than scar tissue. The method involves transforming the most common type of cells found in wounds into fat cells – something that was previously thought to be impossible in humans. Researchers began this work at the Perelman School of Medicine at the University of Pennsylvania, which led to a large-scale, multi-year…
A combination of a diabetes medication and an antihypertensive drug can effectively combat cancer cells. The team of researchers led by Prof. Michael Hall at the Biozentrum of the University of Basel has also reported that specific cancer cells respond to this combination of drugs.
ETH Researchers have used the simplest approach yet to produce artificial beta cells from human kidney cells. Like their natural model, the artificial cells act as both sugar sensors and insulin producers.
When Kerstin Stenson, MD, describes the innovative technique she is helping develop to fight cancer, it seems like she’s describing a Tom Clancy military espionage novel.
Menarini-Silicon Biosystems announced the company’s DEPArray single-cell isolation technology played a key role in a study conducted by researchers from The University of Manchester to develop a model for predicting whether small-cell lung cancer patients will be sensitive or resistant to initial chemotherapy treatment.
n type 1 diabetes, the body attacks its own insulin-producing cells. Scientists at Helmholtz Zentrum München, partner in the German Center for Diabetes Research, and their colleagues at Technical University of Munich have now reported in the journal ‘PNAS’ about a mechanism used by the immune system to prepare for this attack. They were able to inhibit this process through targeted…
Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's. Now, researchers at Johns Hopkins say they have pinpointed the protein at the end of that chain of events, one that delivers the fatal strike by carving up a cell's DNA. The find, they say, potentially…
Nanoparticles known as Cornell dots, or C dots, have shown great promise as a therapeutic tool in the detection and treatment of cancer. Now, the ultrasmall particles – developed more than a dozen years ago by Ulrich Wiesner, the Spencer T. Olin Professor of Engineering at Cornell University – have shown they can do something even better: kill cancer cells without attaching a cytotoxic drug.
When one cell divides into two - that is how all forms of life are propagated - the newly born daughter cells have to be equipped with everything they will need in their tiny lives. Most important of all is that they inherit a complete copy of the genetic information from their mother cell. If this is not the case because a wrong number of chromosomes – on which the genetic information is…
A team of researchers at Yale found that a treatment using bioadhesive nanoparticles loaded with a potent chemotherapy drug proved more effective and less toxic than conventional treatments for gynecological cancer.
For the first time, scientists know what happens to a virus’ shape when it invades a host cell, thanks to an experiment by researchers at Penn State College of Medicine and University of Pittsburgh School of Medicine. Understanding how the virus shape specifically changes could lead to more effective anti-viral therapies.
A small device implanted under the skin can improve breast cancer survival by catching cancer cells, slowing the development of metastatic tumors in other organs and allowing time to intervene with surgery or other therapies. These findings suggest a path for identifying metastatic cancer early and intervening to improve outcomes.
Cancer thrives when mutated cells undergo frequent division. Most anti-cancer drugs work by inserting themselves in between the DNA base pairs that encode our genetic information. This process is known as intercalation, and it can result in subtle changes to the DNA molecule’s geometric shape or tertiary structure. These structural changes interfere with the DNA’s transcription and a cell’s…
Researchers at the Cancer Research UK Cambridge Institute sprayed a dye on oesophageal tissue samples taken from people with Barrett’s oesophagus – a condition that increases the risk of developing oesophageal cancer. The dye sticks to healthy oesophageal cells but not to pre-cancerous cells. They then shone near-infrared light - which is just beyond the red colours that our eyes can normally…
Many cancers only become a mortal danger if they form metastases elsewhere in the body. Such secondary tumours are formed when individual cells break away from the main tumour and travel through the bloodstream to distant areas of the body. To do so, they have to pass through the walls of small blood vessels. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and…
One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.
Australian researchers have made a world-first breakthrough in the early detection of patients' resistance to a common treatment for chronic myeloid leukemia. The discovery offers some hope that the patients' treatment could be changed sooner to improve their chances of survival.
A new, epidemic strain of C. difficile is proving alarmingly deadly, and new research from the University of Virginia School of Medicine not only explains why but also suggests a way to stop it.
They may be slimy, but they are a perfect environment for microorganisms: biofilms. Protected against external influences, here bacteria can grow undisturbed, and trigger diseases. Scientists at Kiel University, in cooperation with colleagues at the Hamburg University of Technology (TUHH) in Hamburg-Harburg, are researching how it can be possible to prevent the formation of biofilms from the…
As part of a national, joint research project in cooperation with Chronix Biomedical (San Jose, CA/USA/Göttingen/Germany), Professor Michael Oellerich MD is on new biomarkers in organ transplantation, aiming to develop personalised immunosuppression for patients. This also entails the development of molecular test procedures, among others for the early detection of rejection. The keyword here is…
Many drug treatments do not work due to their poor ability to reach their intended targets inside patients’ cells. To address this, researchers at Cardiff University’s Schools of Pharmacy and Pharmaceutical Sciences, and Biosciences have designed a highly efficient method to improve the delivery of therapeutic molecules into diseased cells such as those in stomach cancer, breast cancer and…
A receptor, first known for its role in mediating the harmful effects of the environmental pollutant dioxin in our body, is now understood to play other important roles in modulating the innate immune response.
