Nano-paper filter removes viruses

Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature. The research was carried out in collaboration with virologists from the Swedish University of Agricultural Sciences/Swedish...

Mushroom-derived compound could stamp out HPV infe...

A compound derived from mushrooms may provide a new therapeutic option for treating human papillomavirus and curbing HPV-related cancers. Researchers at the University of Texas Health Science Center Medical School at Houston treated HPV-positive mice with active hexose correlated compound, or AHCC, a natural supplement produced from the shiitake mushroom family, and found that a once-daily treatment of the compound began to...

Radiation able to be securely stored in nontoxic m...

Researchers have discovered that microscopic “bubbles” developed at Kansas State University are safe and effective storage lockers for harmful isotopes that emit ionizing radiation for treating tumors. The findings can benefit patient health and advance radiation therapy used to treat cancer and other diseases, said John M. Tomich, a professor of biochemistry and molecular biophysics who is affiliated with the...

New vaccine against common birth defect-causing vi...

An experimental vaccine using a novel defense mechanism may eventually help protect people from a common virus that affects more than half of the U.S. population and causes congenital birth defects in some cases. Using the most common form of white blood cell, called neutrophils, scientists from Cardiff University have found a way to quell cytomegalovirus, or CMV. CMV is a common infection that is part of the herpesvirus...

B-cells aggravate autoimmune diseases

Scientists in Freiburg may have discovered a fundamental aggravating factor in autoimmune diseases. If B-lymphocytes lack the protein PTP1B, the cells will become hyperactive for stimulatory signals and can thus promote an autoimmune attack. This study offers an additional explanation to how B-cells regulate an immune response. In Germany, approximately 800,000 people suffer from rheumatoid arthritis. In this progressive...

Key enzyme in pancreatic cancer growth

A study by the Imperial College London, funded by the U.K. research charity Pancreatic Cancer Research Fund, examined the role of Hedgehog, whose usual job is to send signals to cells in embryos to divide and grow into the correct body parts. But while Hedgehog usually switches off when the embryo is formed, in many cancers, including pancreatic, it becomes abnormally reactivated. Hedgehog cannot function without the help of...
