Organic electrochemical transistors (OECTs) are crucial for next-generation (bio-)electronic devices but are often constrained by the use of aqueous electrolytes, which introduce crosstalk, hinder miniaturization, and limit circuit integration. Here, a photo-patternable solid-state electrolyte based on 𝜄-carrageenan (𝜄-CGN) and poly(ethylene glycol) diacrylate (PEGDA) is presented, enabling high-performance OECTs and complementary circuits. The 𝜄-CGN electrolyte exhibits high ionic conductivity (>10 mS cm), comparable to a 0.

Activated phosphoinositide 3-kinase delta syndrome (APDS) is an autosomal dominant inborn errors of immunity resulting from gain of function mutations in the gene or loss of function mutations in the gene. These mutations lead to hyperactivation of the phosphoinositide 3-kinase/Akt/mammalian target of rapamycin (mTOR) signaling pathways, causing complex deficiencies in cellular and humoral immunity. APDS patients exhibit diverse clinical manifestations including recurrent respiratory infections, nonneoplastic lymphoproliferation, an increasing risk of malignancy, and autoimmune diseases.

To address the substantial variability in immune checkpoint blockade (ICB) therapy effectiveness, we developed an innovative R package called integrated Machine Learning and Genetic Algorithm-driven Multiomics analysis (iMLGAM), which establishes a comprehensive scoring system for predicting treatment outcomes through advanced multi-omics data integration. Our research demonstrates that iMLGAM scores exhibit superior predictive performance across independent cohorts, with lower scores correlating significantly with enhanced therapeutic responses and outperforming existing clinical biomarkers. Detailed analysis revealed that tumors with low iMLGAM scores display distinctive immune microenvironment characteristics, including increased immune cell infiltration and amplified antitumor immune responses.

The elastic modulus is a critical parameter for the design of conjugated polymers for wearable electronics and correlates with electrical and thermal transport. Yet, widely different values have been reported for the same material because of the influence of processing and measurement conditions, including the temperature, mode, direction, and time scale of deformation. Thus, results obtained via different methods are usually not considered to be comparable.

RelA deficiency resulting from mutations in the human gene is a recently identified inborn errors of immunity (IEI). The gene encodes the RelA (p65) protein, one of the five transcription factors of the NF-κB family, which plays a critical role in the regulation of transcriptional programs essential for the development and maintenance of the immune system, skeletal system, and epithelial tissues. RelA deficiency is classified as RelA haploinsufficiency and RelA dominant-negative.

Conductive polymers have become crucial in advancing various electronic applications. While p-type materials like poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) are widely used and produced at scale, the development of high-performance n-type polymers has lagged due to challenges in synthesis and scalability. In this work, a novel method is introduced to synthesize the highly conductive n-type polymer poly(benzodifurandione) (PBFDO) using α-tocopherylquinone (α-TQ) as a catalyst.

Article Synopsis
  • The text discusses a case of a newborn girl with autoimmune lymphoproliferative syndrome (ALPS) caused by novel compound heterozygous variants in the FAS gene, which is linked to immune system dysfunction.
  • Various methods, such as whole-exome sequencing and flow cytometry, were used to analyze the impact of these variants on FAS expression and T cell apoptosis, revealing significant defects and an unusual immunophenotype in the patient.
  • The findings suggest that the identified FAS mutations lead to impaired immune responses and early disease manifestation, with potential improvement through sirolimus treatment targeting mTOR pathway abnormalities.

Radiotherapy resistance is the main cause of treatment failure among patients with nasopharyngeal carcinoma (NPC). Recently, increasing evidence has linked the presence of intratumoral Fusobacterium nucleatum (Fn) with the malignant progression and therapeutic resistance of multiple tumor types, but its influence on NPC has remained largely unknown. We found that Fn is prevalent in the tumor tissue of patients with NPC and is associated with radioresistance.

Chemical doping is an important approach to manipulating charge-carrier concentration and transport in organic semiconductors (OSCs) and ultimately enhances device performance. However, conventional doping strategies often rely on the use of highly reactive (strong) dopants, which are consumed during the doping process. Achieving efficient doping with weak and/or widely accessible dopants under mild conditions remains a considerable challenge.
