Phase-separating Pt(IV)-graft-glycopeptides sequentially sensing pH and redox for deep tumor penetration and targeting chemotherapy.

Active-targeting nanomedicines have been widely employed in cancer treatment for increasing therapeutic index. However, the limited permeability caused by the binding site barrier (BSB) and size hindrances compromises their clinical antitumor efficacy in patients. Herein, learning from the liquid-liquid phase separation (LLPS) of bio-macromolecules, we report phase-separating glycopeptides (HEP) from polyhistidine (PHis) grafted hyaluronic acid (HA), which can sense the tumor extracellular pH and concomitantly overcome size and BSB dilemmas for enhanced tumor penetration.

Mineral and Microbial Properties Drive the Formation of Mineral-Associated Organic Matter and Its Response to Increased Temperature.

A comprehensive understanding of the formation of mineral-associated organic matter (MAOM) is a prerequisite for the sustainable management of soil carbon (C) and the development of effective long-term strategies for C sequestration in soils. Nevertheless, the precise manner by which microbial and mineral properties drive MAOM formation efficiency and its subsequent response to elevated temperature at the regional scale remains unclear. Here, we employed isotopically labelled laboratory incubations (at 15°C and 25°C) with soil samples from a ~3000 km transect across the Tibetan Plateau to elucidate the mechanisms underlying MAOM formation and its temperature response.

HBV DNA polymerase upregulates the transcription of PD-L1 and suppresses T cell activity in hepatocellular carcinoma.

Background: In HBV-associated HCC, T cells often exhibit a state of functional exhaustion, which prevents the immune response from rejecting the tumor and allows HCC to progress. Moreover, polymerase-specific T cells exhibit more severe T-cell exhaustion compared to core-specific T cells. However, whether HBV DNA polymerase drives HBV-specific CD8 T cell exhaustion in HBV-related HCC remains unclear.

Single-Layer Wide-Angle Scanning Linear Phased Arrays Based on Multimode Microstrip Patch Elements.

This paper introduces a novel single-layer microstrip patch element designed to achieve a wide beamwidth, in order to address the growing demand for wide-angle scanning capabilities in modern phased array systems. The proposed element, comprising a slot-etched circular patch and an array of metallized holes arranged in square rings, offers a unique approach to beam shaping. By carefully adjusting parameters such as the slot structure and feeding position, our element is engineered to simultaneously excite both the TM and TM modes, a key feature that contributes to its wide beamwidth characteristics.

Spatiotemporally sequential delivery of biomimetic liposomes potentiates glioma chemotherapy.

As one of the most challenging cancers, glioma still lacks efficient therapeutic treatment in clinics. The dilemmas of nanodrug-based therapies for glioma are due not only the limited permeability of the blood-brain barrier (BBB) but also the deficiency of targeting tumor lesions. Thus, spatiotemporally sequential delivery of therapeutics from BBB-crossing to glioma accumulation is considered a strategy to obtain better outcomes.
