Photonic-assisted broadband RF receivers with low IF frequencies based on Kramers-Kronig processing.

A simplified photonic-based radio frequency (RF) receiver with a low intermediate frequency (IF) is proposed and experimentally demonstrated by utilizing direct detection and Kramers-Kronig (KK) processing. In the proposed approach, the RF and local oscillator (LO) signals are modulated onto an optical carrier using a dual-drive Mach-Zehnder modulator (DDMZM) biased at a minimum transmission point. The modulated optical signal is then directed to a single photodetector (PD) to produce the IF signal, which is designed to fall within 1.

Structural and mechanistic insights into the transcriptional regulation of chromosomal T6SS by large conjugative plasmid-encoded TetRs in Acinetobacter baumannii.

The type VI secretion system (T6SS) is a highly sophisticated nanomachine widely used by bacteria to achieve competitive advantage, important for survival and pathogenicity. In Acinetobacter baumannii, the large conjugative plasmid pAB3 encodes two TetR-family transcriptional regulators, TetR1 and TetR2, that play crucial roles in restricting T6SS function and promoting recipient survival after conjugation. Using X-ray crystallography, we demonstrate that the plasmid-encoded TetRs are structurally homologous but distinct in DNA sequence binding preferences, which we have also mapped out using chromatin immunoprecipitation and validated with electrophoretic mobility shift assay and isothermal titration calorimetry.

Small extracellular vesicles derived from mesenchymal stromal cells loaded with β-nicotinamide mononucleotide activate NAD/SIRT3 signaling pathway-mediated mitochondrial autophagy to delay skin aging.

Background: Recently, the beneficial effects of human umbilical cord mesenchymal stromal cell (hucMSC)-derived small extracellular vesicles (sEVs) in mitigating skin aging through multiple mechanisms have been widely reported. β-Nicotinamide mononucleotide (NMN) is an iconic anti-aging drug that increases NAD levels in the body to slow down, ameliorate, and prevent various phenotypes associated with aging, but its high water solubility, low permeability, and instability limit its clinical application. Based on this, we applied electroporation to construct NMN-loaded hucMSC-sEVs (NMN-sEVs) to improve their stability and efficacy and to enhance their potential for translational application in medical aesthetics and anti-aging.

Augmenting osteoporotic osseointegration through a temporal release nanocoating-based reversing dysregulated osteogenic microenvironment.

Rationale: Imbalances in the osteogenic-osteoclastic microenvironment hinder effective osseointegration between the prosthesis and host bone, which is a key factor contributing to the high incidence of prosthesis loosening and periprosthetic fractures in osteoporosis patients. Developing an implant interface that can reverse the dysregulated osteogenic microenvironment is an effective strategy to address this challenge.

Methods: A novel bioinspired interface with a spatial gradient structure was engineered by 3D-printed porous titanium alloy implants and hollow mesoporous silica nanoparticles coating.

Targeting CD38 to alleviate brain endothelial cell dysfunction and cognitive impairment in vascular dementia.

Vascular dementia (VaD) is a leading cause of cognitive decline, closely associated with cerebrovascular endothelial cell (CEC) dysfunction, blood-brain barrier (BBB) disruption, and neuroinflammation.
