Metal-organic cages improving microporosity in polymeric membrane for superior CO capture.
Sci Adv
January 2025
CAS Key Laboratory of Urban Pollutant Conversion, Department of Environmental Science and Engineering, University of Science and Technology of China, Hefei, Anhui 230026, China.
Mixed matrix membranes, with well-designed pore structure inside the polymeric matrix via the incorporation of inorganic components, offer a promising solution for addressing CO emissions. Here, we synthesized a series of novel metal organic cages (MOCs) with aperture pore size precisely positioned between CO and N or CH. These MOCs were uniformly dispersed in the polymers of intrinsic microporosity (PIM-1).

Exogenous neural stem cells (NSCs) have great potential to reconstitute damage spinal neural circuitry. However, regulating the metabolic reprogramming of NSCs for reliable nerve regeneration has been challenging. This report discusses the biomimetic dextral hydrogel (DH) with right-handed nanofibers that specifically reprograms the lipid metabolism of NSCs, promoting their neural differentiation and rapid regeneration of damaged axons.

JAMA Surg
January 2025
Vanderbilt University Medical Center, Nashville, Tennessee.
Importance: Fracture-related infection (FRI) is a serious complication following fracture fixation surgery. Current treatment of FRIs entails debridement and 6 weeks of intravenous (IV) antibiotics. Lab data and retrospective clinical studies support use of oral antibiotics, which are less expensive and may have fewer complications than IV antibiotics.

Chinese University of Hong Kong, Shenzhen, Shenzhen, Guangdong, China.
In most solid tumors, cellular energy metabolism is primarily dominated by aerobic glycolysis, which fulfills the high demand for biomacromolecules at the expense of reduced ATP production efficiency. Elucidation of the mechanisms by which rapidly proliferating malignant cells acquire sufficient energy in this state of inefficient ATP production from glycolysis could enable development of metabolism targeted therapeutic strategies. In this study, we observed a significant association between elevated expression levels of the long non-coding RNA (lncRNA) SNHG17 and unfavorable prognosis in breast cancer (BCa).

Department of Computational Chemistry, Lund University, Chemical Centre, P. O. Box 124, SE-221 00 Lund, Sweden.
Particulate methane monooxygenase (pMMO) is the most efficient of the two groups of enzymes that can hydroxylate methane. The enzyme is membrane bound and therefore hard to study experimentally. For that reason, there is still no consensus regarding the location and nature of the active site.
