A Study Discover New Targets for Targeting Caliciviruses

Norovirus is highly contagious and very difficult to control. In general, the Norovirus epidemic broke out in hospitals, nursing homes, schools, hotels, and cruise ships. Calicivirus, including Norovirus and sapovirus, is also an important animal pathogen, leading to ‘cat flu’ associated with high mortality in domestic cats. In a new study, British researchers used cryo-electron microscopy to study the structure of the feline calicivirus that causes cat flu to better…

New Developed Methods to Map The Mouse Brain with Unprecedented Precision

The prior technology can make the tissue as clear and transparent as glass and expand it to several times its original size, which provides an unprecedented opportunity for the internal operation of the biopsy system. Recently, Japanese researchers mapped the cellular composition of the mouse brain with unprecedented precision.   System biologist Ueda Taiji and his team at the RIKEN Biosystems Dynamics Research Center in Japan used a technique called…

Cell: New Research Reveals an Unexpected Mechanism of Action of Antibodies

In a new study, researchers from research institutions such as the University of Washington in the United States studied monoclonal antibodies which were isolated from survivors of the severe acute respiratory syndrome (SARS) or Middle East Respiratory Syndrome (MERS) caused by the coronavirus. These monoclonal antibodies reveal an alarming immune defense strategy against deadly viruses. Atomic and molecular information for these highly potent antibodies may provide new insights into these…

New Nmr Technology Enables More Sensitive Detection of Biomolecule Structures

Nuclear magnetic resonance spectroscopy is a technique used to study the structure and composition of various molecules, including proteins associated with Alzheimer’s disease and other diseases. Recently, researchers at the Massachusetts Institute of Technology have developed a method to significantly improve the sensitivity of nuclear magnetic resonance spectroscopy (NMR).   Robert Griffin, a professor of chemistry at Arthur Amos Noyes, said that with this new approach, scientists should be able…

Advanced Imaging Technology Helps Reveal The Internal Features of The Tumor

Recently, researchers at the Lyon Cancer Research Center have demonstrated the potential of imaging technology to study oncology issues. Advanced imaging techniques can differentiate malignant cell populations and monitor the effectiveness of anticancer therapies. The study result is published in the Journal of Physical Review Letters, helping to design new therapeutic molecules and personalization of treatment.   Despite a good understanding of the biology of cancer, 90% of experimental drugs…

Nature: Tc Toxin Activation Requires Unfolding and Refolding of a β-Propeller

Bacteria have established strategies for infecting organisms and utilize them as a source of nutrients. Many bacteria use their secreted toxins to simply pierce the outer shell of the cell to destroy the cell membrane. Human pathogens such as Yersinia pestis or other bacteria from Salmonella produce a more subtle mechanism: injecting their toxic substances by using a special toxin complex.   Bacterial toxins are one of the most effective…

Neuron: Whole-Brain Imaging of Mice during Behavior

In a recent study described in the journal Neuron, the Emily Macé and collaborators of the Botond Roska team demonstrated how functional ultrasound imaging can produce high-resolution full-motion images of the brain for specific behaviors in mice. This non-invasive technique has broad application prospects in ophthalmology, neurological and psychiatric diseases.   “Functional ultrasound imaging produces higher resolution images, and is simpler, cheaper, and easier to use than functional magnetic resonance…
