The mechanism of pathogenic bacteria crossing the human blood-brain barrier has been discovered

Source: China Science Daily

Recently, Professor Wang Lei's team from Nankai University revealed for the first time that the three main bacteria that cause meningitis use the same mechanism to cross the blood-brain barrier, and elaborated on their molecular mechanisms, which are of great significance for the prevention and treatment of meningitis. The research findings are published online in the internationally renowned academic journal "Proceedings of the National Academy of Sciences".

Bacterial meningitis is an inflammatory reaction caused by pathogenic bacteria infection, including meninges, arachnoid membranes and pia mater. It has a high incidence rate and mortality. Even after treatment, it may also be accompanied by cerebral palsy, mental retardation, epilepsy and other neurological sequelae. It has become one of the global public health problems. Therefore, in-depth research on the pathogenic mechanism of meningitis pathogenic bacteria and the search for effective treatment and prevention and control methods for pathogenic bacterial infections has always been one of the research hotspots in the field of microbiology. The blood-brain barrier can protect the central nervous system from harmful substances or bacteria in the blood entering the brain, while meningitis pathogenic bacteria can cross the blood-brain barrier, invade the brain, and cause inflammation. However, the molecular mechanism of this crossing mechanism has not been elucidated. The research team at Nankai University has focused on this key issue and, after years of research, found that the main pathogenic bacteria of meningitis - Streptococcus pneumoniae, Group B Streptococcus, and Escherichia coli from neonatal meningitis - cross the blood-brain barrier by hijacking the intracellular transport of iron transporter receptors (TfR). The research results suggest that the main pathogenic bacteria of meningitis use a common mechanism to cross the blood-brain barrier. Therefore, the discovery of this mechanism provides a theoretical basis and potential targets for the development of broad-spectrum drugs for the prevention and treatment of bacterial meningitis, and also provides new ideas for delivering drugs across the blood-brain barrier.

New research reveals the inflection point of Himalayan precipitation changes caused by aerosol emission reduction

Source: China Science Daily

Recently, the research team of Zhou Tianjun, a researcher from the Institute of Atmospheric Physics of the Chinese Academy of Sciences, and scholars from the Pacific Northwest National Laboratory of the United States, the Max Planck Institute of Meteorology of Germany and the Ocean University of China, revealed the driving factors and dynamic mechanisms that have caused the "dual core" changes in summer precipitation in Asia's alpine regions, with the Qinghai Tibet Plateau as the main body, since the 1950s, and the inflection points of future Himalayan precipitation changes. The new research provides a new scientific perspective for addressing climate change.

The changes in precipitation in the high mountain areas of Asia, with the Qinghai Tibet Plateau as the main body, are related to glacier water reserves and ecological environment changes. The turning point of the Himalayan Mountains in the southeast of the plateau from 'drying' to 'wetting' in the future is a matter of public concern. We hope that the team's research results can provide scientific reference for effectively addressing regional climate change. "Corresponding author Zhou Tianjun of the paper pointed out. The relevant research results were published in Nature on October 11th.

Discovery of Dinosaur Footprint Fossils for the First Time in Hami's "Pterosaur Eden"

Hami is the largest and most abundant pterosaur fossil producing area in the world, where hundreds of millions of pterosaurs have once thrived and thrived, making it a truly 'pterosaur Eden'. Recently, Wang Xiaolin, a researcher of the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, cooperated with Shenyang Normal University and Hami Museum, and published research results on the footprints of theropods of the Hami pterosaur fauna in the international academic journal Historical Biology. This is also the first discovery of Cretaceous dinosaur footprints in the Hami and Tuha basins, increasing the diversity of the Hami pterosaur fauna.

Footprint fossils, as an important type of trace fossils, are important in obtaining information on paleontological ecological habits that skeletal fossils cannot provide. In recent years, the Hami scientific research team led by Wang Xiaolin has successively discovered some theropod footprints fossils, which come from the Shengjinkou Formation of the Lower Cretaceous Tugulu Group in the Yadan area of the Hami Gobi in the Tuha Basin, dating back approximately 130 to 120 million years. In addition to theropod footprints, the scientific research team also discovered a group of footprints including sauropod dinosaurs, pterosaurs, birds, and turtles.

Hong Kong University research indicates that excessive intake of red meat may increase the risk of cardiovascular disease and diabetes

The School of Medicine of the University of Hong Kong announced on the 9th that the team of the School of Public Health found that excessive consumption of red meat could increase the risk of cardiovascular disease and diabetes through large-scale analysis of research data of more than 4.4 million people. In addition, the research team also found that the risk ratio of stroke and type 2 diabetes caused by the oriental diet culture was lower than that in the west.

The research team believes that this is mainly due to the high intake of red meat, butter, high-fat dairy products, and refined grains in Western dietary cultures, while the intake of whole grains, vegetables, and seafood is higher in Eastern diets, with relatively less red meat.
