  摘要：The mu -opioid receptor (mu OR) is a well-established target for analgesia1, yet conventional opioid receptor agonists cause serious adverse effects, notably addiction and respiratory depression. These factors have contributed to the current opioid overdose epidemic driven by fentanyl2, a highly potent synthetic opioid. mu OR negative allosteric modulators (NAMs) may serve as useful tools in preventing opioid overdose deaths, but promising chemical scaffolds remain elusive. Here we screened a ...
• If bird flu sparks a human pandemic, your past immunity could help AI翻译
  作者：Kozlov, Max
  摘要：Older populations might be more protected than younger ones because of exposure to 'matched' strains during childhood, but an H5N1 pandemic is likely to take a major toll all the same.

  摘要：The Warburg effect is a hallmark of cancer that refers to the preference of cancer cells to metabolize glucose anaerobically rather than aerobically1,2. This results in substantial accumulation of lacate, the end product of anaerobic glycolysis, in cancer cells3. However, how cancer metabolism affects chemotherapy response and DNA repair in general remains incompletely understood. Here we report that lactate-driven lactylation of NBS1 promotes homologous recombination (HR)-mediated DNA repair....
• Electron holography observation of individual ferrimagnetic lattice planes AI翻译

  摘要：Atomic-scale observations of a specific local area would be considerably beneficial when exploring new fundamental materials and devices. The development of hardware-type aberration correction1,2 in electron microscopy has enabled local structural observations with atomic resolution3-5 as well as chemical and vibration analysis6-8. In magnetic imaging, however, atomic-level spin configurations are analysed by electron energy-loss spectroscopy by placing samples in strong magnetic fields9-11, w...

  摘要：A long-standing challenge is how to formulate proteins and vaccines to retain function during storage and transport and to remove the burdens of cold-chain management. Any solution must be practical to use, with the protein being released or applied using clinically relevant triggers. Advanced biologic therapies are distributed cold, using substantial energy, limiting equitable distribution in low-resource countries and placing responsibility on the user for correct storage and handling. Cold-...
• Serious errors plague DNA tool that's a workhorse of biology AI翻译
  作者：Bourzac, Katherine
  摘要：Researchers analysed thousands of laboratory-made plasmids and discovered that nearly half of them had defects, raising questions of experimental reproducibility.

  作者单位：Ministry of Health - Uganda; Fred Hutchinson Cancer Center
  摘要：Gene therapies will become more affordable everywhere only if they are developed and produced in the regions where they are most needed.
