Investigating the delivery of PD-L1-targeted immunoliposomes in a dynamic cervical cancer-on-a-chip model.

The recent approval of pembrolizumab in recurrent or metastatic cervical cancer warrants further investigations into the usefulness of immunotherapies for more durable and less radical interventions. In this study, the targeting potential of anti-PD-L1-functionalized immunoliposomes was tested in a 3D in vitro cervical cancer-on-a-chip model. Immunolipsomes were synthesized and decorated externally with monovalent anti-PD-L1 Fab' fragments of commercially available atezolizumab.

Dually Fluorinated Unimolecular Micelles for Stable Oxygen-Carrying and Enhanced Photosensitive Efficiency to Boost Photodynamic Therapy against Hypoxic Tumors.

Tumor hypoxia is one of key challenges in deep tumor photodynamic therapy (PDT), and how to fix this issue is attracting ongoing concerns worldwide. This work demonstrates dually fluorinated unimolecular micelles with desirable and stable oxygen-carrying capacity, high cellular penetration, and integrative type I & II PDT for deep hypoxic tumors. Dually fluorinated star copolymers with fluorinated phthalocyanines as the core are prepared through photoinitiated electron/energy transfer-reversible addition-fragmentation chain transfer (PET-RAFT) polymerization under irradiation with NIR LED light at room temperature, followed by assembly into unimolecular micelles.

Mechanisms of immune responses in Acanthopagrus latus to Streptococcus agalactiae infection revealed by transcriptomic analysis.

Acanthopagrus latus (yellowfin seabream) is an economically important fish in the southeast coastal sea of China. Its slower growth rate makes it more prone to diseases in the cultivation period, leading to substantial economic losses. Epidemiological investigations have indicated that Streptococcus agalactiae is one of the most common Gram-positive pathogens, which have garnered increasing attention due to its high contagion and lethality rates in A.

A novel carbazole-pyrimidine-based dual mode fluorescent probe for detection of acidic and basic pH in biological systems.

pH balance is an important factor in regulating the internal environment of body and maintaining the normal physiological activities, but pH cannot be detected in vivo without damaging the tissue. It is important to develop a pH probe with low toxicity, high sensitivity and targeting of organelles. In this research, a novel carbazole-pyrimidine-based probe PKZP was designed from 2-hydroxyl-3-pinanone which was derived from natural monoterpene α-pinene for detecting both acidic and basic pH in vivo.

CS bonds mediated rapid charge transfer in hm-CN/CdS heterostructure for efficient photocatalytic CO reduction.

The quest for stable and high-performance photocatalysts is pivotal in advancing the field of photocatalytic CO reduction. Traditional single-component semiconductors are often impeded by their inability to concurrently achieve a broad light absorption spectrum, efficient separation of photogenerated charge carriers, and enduring stability, thereby constraining their photocatalytic efficacy. In this study, we introduce an innovative hm-CN/CdS heterojunction that broadens the light absorption spectrum and significantly enhances the separation efficiency of photogenerated charge carriers.

Protein Phosphatase 2A B'α and B'β promote pollen wall construction partially through BZR1-activated CEP1 in Arabidopsis.

A well-constructed pollen wall is essential for pollen fertility, which relies on the contribution of tapetum. Our results demonstrate an essential role of the tapetum-expressed protein phosphatase 2A (PP2A) B'α and B'β in pollen wall formation. The b'aβ double mutant pollen grains harbored sticky remnants and tectum breakages, resulting in failed release.

Creatine Supplementation Beyond Athletics: Benefits of Different Types of Creatine for Women, Vegans, and Clinical Populations-A Narrative Review.

Creatine monohydrate supplementation is widely used by athletes in high-intensity, power-based sports due to its ability to enhance short-term performance by increasing intramuscular phosphocreatine (PCr) stores, which aid in ATP resynthesis during intense muscle contractions. However, emerging evidence suggests that creatine monohydrate offers benefits beyond athletic performance. This narrative review explores the literature supporting the advantages of creatine supplementation in women, vegans, and clinical populations.

Yolk and Casein Sequence Self-Assembly for Low-Oil Emulsion Gel and Its Application in Low-Fat Mayonnaise.

High dietary fat food such as mayonnaise (70-80% oil content) can induce obesity and cardiovascular diseases, thus reducing their oil content is required. However, the development of low-fat mayonnaise is still a big challenge since reducing oil content will increase the fluidity, induce phase separation and decrease the stability of mayonnaise. Herein, we provide a novel strategy for developing yolk-casein-based low-fat mayonnaise (30% oil content) with a similar texture to commercial high-fat mayonnaise through post-acidification.
