Case report: Therapeutic response of front-line cadonilimab plus chemotherapy on patient with advanced lung adenocarcinoma harboring STK11 genetic aberration.

The STK11 gene mutation is a common genetic alteration in non-small cell lung cancer (NSCLC) and is significantly associated with poor responses to current immunotherapy regimens. Despite its prevalence, there is currently no established standard for front-line treatment in this subtype of NSCLC, underscoring the increasing need for personalized therapeutic strategies. In this report, we present a case of a patient with STK11-mutant NSCLC who was treated with first-line cadonilimab (10mg/kg) in combination with pemetrexed (500mg/m^2) plus carboplatin (AUC=5), resulting in a notable extension of progression-free survival (PFS).

A Dual-Functional Sulfur-rich Copolymers for Stable Anchoring and Enhanced Conversion of Polysulfide in Lithium-Sulfur Batteries.

Sulfur-rich copolymers have gained a great deal of attention as promising cathode materials in Li-S batteries due to their low cost and naturally uniform sulfur dispersion. However, the poor electrical conductivity and shuttle effect cause rapid capacity decay and low sulfur utilization especially under high sulfur loading and low electrolyte/sulfur ratio. Herein, the Fe1-xS/C dispersed and Se-containing sulfur-rich polymer (FSP) was synthesized by one-pot reaction of ferrocene, trithioiynuric acid with SexSy.

Efficient extraction and analysis method for lead-containing nanoparticles in complex biological samples to eliminate "false" interferences by using SP-ICP-MS.

Metal-containing nanoparticles (MNPs) ubiquitously exist in the environment and organisms, playing distinct roles in the fate and toxicity of metals. However, the extraction and analysis of the MNPs in biological samples is still a great challenge and the interferences of other metal species and complex matrices remains unclear. In this work, we established a method for efficient extraction and accurate analysis of MNPs in biological samples to eliminate the interference caused by metal ions and biological matrices based on the alkali extraction and single particle mode inductively coupled plasma mass spectrometry (SP-ICP-MS).

pH-dependent cadmium binding to hemoglobin: Implications for human excretion.

Half-life of cadmium (Cd) in blood is around 3-4 months, which is much shorter than its half-life in human organs (30 years). Promoting the elimination of Cd from the blood is a crucial step in reducing the body's Cd burden. However, there is currently no effective method available to facilitate this process.

Deciphering basic and key traits of bio-pollutants in a long-term reclaimed water headwater urban stream.

Reclaimed water has been recognized as a stable water resource for ecological replenishment in riverine environment. However, information about the bio-pollutants spatial and temporal distributions and the associated risk in this environment remains insufficient. Herein, the bio-pollutant profile in a long-term reclaimed water headwater urban stream, including antibiotic resistance genes (ARGs), mobile genetic elements and pathogens, were revealed by metagenomics.

Droplet-based bioprinting for the tailored fabrication of bacteria-laden living materials.

Droplet-based bioprinting (DBB) allows for high precision, noncontact, and on-demand distribution of bioinks, hence it has been widely utilized in the preparation of bacteria-laden living materials (BLMs). Nonetheless, discontinuous ink deposition makes it challenging to fabricate large-sized intact living structures via this technique. Herein, we explore the way of using DBB to construct centimeter-scale BLMs with bespoke geometries, and further demonstrate its potential applicability in sensing-responsive device by integrating engineered bacteria.

Poly(thioctic acid) Hydrogels Integrated with Self-Healing, Bioadhesion, Antioxidation, and Antibiosis for Infected Wound Treatment.

Bacterial infections pose significant challenges in wound healing and are a serious threat to human health. Hydrogels have emerged as an ideal wound dressing due to their three-dimensional network, which facilitates exudate absorption and maintains a moist environment conducive to healing. Herein, we developed integrated hydrogels composed of poly(thioctic acid) (PTA), polydopamine (PDA), and curcumin (Cur).

A continuous pursuit dataset for online deep learning-based EEG brain-computer interface.

This dataset is from an EEG brain-computer interface (BCI) study investigating the use of deep learning (DL) for online continuous pursuit (CP) BCI. In this task, subjects use Motor Imagery (MI) to control a cursor to follow a randomly moving target, instead of a single stationary target used in other traditional BCI tasks. DL methods have recently achieved promising performance in traditional BCI tasks, but most studies investigate offline data analysis using DL algorithms.

Transcranial focused ultrasound remotely modulates extrastriate visual cortex by stimulating frontal eye field with subregion specificity.

Low-intensity transcranial focused ultrasound (tFUS) has emerged as a powerful neuromodulation tool characterized by its deep penetration and precise spatial targeting to influence neural activity. Our study directed low-intensity tFUS stimulation onto a region of prefrontal cortex (the frontal eye field, or FEF) of a rhesus macaque to examine its impact on a remote site, the extrastriate visual cortex (area V4) through this top-down modulatory circuit that has been studied extensively with electrical microstimulation.To measure the impact of tFUS stimulation, we recorded local field potentials and multi-unit spiking activities from a multi-electrode array implanted in the visual cortex.

Curcumin-incorporated EGCG-based nano-antioxidants alleviate colon and kidney inflammation via antioxidant and anti-inflammatory therapy.

Natural remedies are gaining attention as promising approaches to alleviating inflammation, yet their full potential is often limited by challenges such as poor bioavailability and suboptimal therapeutic effects. To overcome these limitations, we have developed a novel nano-antioxidant (EK) based on epigallocatechin gallate (EGCG) aimed at enhancing the oral and systemic bioavailability, as well as the anti-inflammatory efficacy, of curcumin (Cur) in conditions such as acute colon and kidney inflammation. EK is synthesized using a straightforward Mannich reaction between EGCG and L-lysine (K), resulting in the formation of EGCG oligomers.

Antioxidant hydrogels for the treatment of osteoarthritis: mechanisms and recent advances.

Articular cartilage has limited self-healing ability, resulting in injuries often evolving into osteoarthritis (OA), which poses a significant challenge in the medical field. Although some treatments exist to reduce pain and damage, there is a lack of effective means to promote cartilage regeneration. Reactive Oxygen Species (ROS) have been found to increase significantly in the OA micro-environment.

Weakening of global terrestrial carbon sequestration capacity under increasing intensity of warm extremes.

The net ecosystem exchange (NEE), determining terrestrial carbon sequestration capacity, is strongly controlled by climate change and has exhibited substantial year-to-year fluctuations. How the increased frequency and intensity of warm extremes affect NEE variations remains unclear. Here, we combined multiple NEE datasets from atmospheric CO inversions, Earth system models, eddy-covariance data-driven methods and climate datasets to show that the terrestrial carbon sequestration capacity is weakened during warm extreme occurrences over the past 40 years, primarily contributed by tropical regions (81% ± 48%).
