Angstrom-scale silver particle-embedded carbomer gel promotes wound healing by inhibiting bacterial colonization and inflammation
Poor wound healing after diabetes or extensive burn remains a challenging problem. Recently, we presented a physical approach to fabricate ultrasmall silver particles from Ångstrom scale to nanoscale and determined the antitumor efficacy of Ångstrom-scale silver particles (AgÅPs) in the smallest size range. Here we used the medium-sized AgÅPs (65.9 ± 31.6 Å) to prepare carbomer gel incorporated w

RING1B recruits EWSR1-FLI1 and cooperates in the remodeling of chromatin necessary for Ewing sarcoma tumorigenesis
Ewing sarcoma (EwS) is an aggressive tumor that affects adolescents and young adults. EwS is defined by a chromosomal translocation, EWSR1-FLI1 being the most common, that causes genome reprogramming through remodeling of enhancers. Here, we describe an unexpected function of RING1B, which is highly expressed in EwS. While retaining its repressive activity at Polycomb developmental regulated gene

VGLL4 promotes osteoblast differentiation by antagonizing TEADs-inhibited Runx2 transcription
VGLL4 has been identified as a YAP inhibitor. However, the exact function of VGLL4 in bone development and bone homeostasis remains unclear. In this study, we demonstrated that VGLL4 breaks TEADs-mediated transcriptional inhibition of RUNX2 to promote osteoblast differentiation and bone development. We found that knockout of VGLL4 in mesenchymal stem cells and preosteoblasts showed osteoporosis a

Mycobacterial EST12 activates a RACK1-NLRP3-gasdermin D pyroptosis-IL-1{beta} immune pathway
Pyroptosis, an inflammatory form of programmed cell death, has been implicated in eliminating pathogenic infections.

Here, we identified a cell pyroptosis–inducing protein, Rv1579c, named EST12, secreted from the M.tb H37Rv region of difference 3. EST12 binds to the receptor for

Protecting hot carriers by tuning hybrid perovskite structures with alkali cations
Successful implementation of hot carrier solar cells requires preserving high carrier temperature as carriers migrate through the active layer.

Seabird establishment during regional cooling drove a terrestrial ecosystem shift 5000 years ago
The coastal tussac ( Poa flabellata ) grasslands of the Falkland Islands are a critical seabird breeding habitat but have been drastically reduced by grazing and erosion. Meanwhile, the sensitivity of seabirds and tussac to climate change is unknown because of a lack of long-term records in the South Atlantic. Our 14,000-year multiproxy record reveals an ecosystem state shift following seabird es

Absence of ice-bonded permafrost beneath an Arctic lagoon revealed by electrical geophysics
Relict permafrost is ubiquitous throughout the Arctic coastal shelf, but little is known about it near shore. The presence and thawing of subsea permafrost are vital information because permafrost stores an atmosphere's worth of carbon and protects against coastal erosion. Through electrical resistivity imaging across a lagoon on the Alaska Beaufort Sea coast in summer, we found that the subsurfa

Sexual dimorphism in the meiotic requirement for PRDM9: A mammalian evolutionary safeguard
In many mammals, genomic sites for recombination are determined by the histone methyltransferase PRMD9. Some mouse strains lacking PRDM9 are infertile, but instances of fertility or semifertility in the absence of PRDM9 have been reported in mice, canines, and a human female. Such findings raise the question of how the loss of PRDM9 is circumvented to maintain fertility. We show that genetic back

På senare år har tekniker inom bröstbevarande kirurgi, onkoplastik, utvecklats för att vid behandling av bröstcancer förbättra både det funktionella och estetiska resultatet. Onkoplastik är lika säker som konventionell bröstbevarande kirurgi vid bröstcancer och patienternas hälsorelaterade livskvalitet ökar. Det framkommer i en ny avhandling från Lunds universitet.
