Pickering emulsion gels received extensive attention in encapsulating fat-soluble substances such as Lycium barbarum seed oil (LBSO). However, the gels presented poor mechanical properties, otherwise, their physical encapsulation cannot inhibit lipid peroxidation. Herein, grape seed proanthocyanidins (OPCs) and casein (CAS) complexes interacted through hydrogen and covalent bonds were proposed to build Pickering emulsion gels and encapsulate LBSO, which changed the secondary structures of CAS and further enhanced emulsifying ability, oxidation resistance, and gelling performance.

Choline acetyltransferase (ChAT) is crucial for acetylcholine synthesis and regulates diverse functions in numerous biological processes. Omeprazole, an inhibitor on human ChAT, was evaluated here on insect ChAT as a potential inhibitor, as well as its insecticidal potency on Nilaparvata lugens, a major insect pest on rice. The evaluation also included omeprazole analogs and α-NETA, in order to explore a superior leading compound targeting on insect ChAT.

Article Synopsis
  • The study aimed to assess how different levels of thyroid-stimulating hormone (TSH) affect tumor progression and survival in patients with early-stage papillary thyroid cancer treated with microwave ablation (MWA).
  • It analyzed the medical records of 525 patients, categorizing them into uni-focal (U-PTC) and multifocal (M-PTC) groups based on TSH levels after treatment, and observed the rates of tumor progression and survival outcomes.
  • Results indicated that lower TSH levels in U-PTC patients correlated with higher tumor progression rates and reduced progression-free survival compared to medium and high TSH levels, whereas M-PTC patients showed no significant relationship between TSH levels and progression.

Natural enemies are essential for the integrated pest management (IPM) strategy in insect pest control. However, chemical pesticides remain the primary method for insect pest control, diminishing natural enemies and causing environmental contamination. The wolf spider (Pardosa pseudoannulata), a major enemy in agro-ecosystem, exhibits maternal care (MC) behaviors such as eggsac-carrying and pulli-carrying, which are crucial for population growth.

Background: Recent advancements in spatially resolved transcriptomics (SRT) have opened up unprecedented opportunities to explore gene expression patterns within spatial contexts. Deciphering spatial domains is a critical task in spatial transcriptomic data analysis, aiding in the elucidation of tissue structural heterogeneity and biological functions. However, existing spatial domain detection methods ignore the consistency of expression patterns and spatial arrangements between spots, as well as the severe gene dropout phenomenon present in SRT data, resulting in suboptimal performance in identifying tissue spatial heterogeneity.

Purpose: The purpose of this study was to compare the actual corneal consumption and subsequent corneal biomechanical changes after small incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (FS-LASIK) in eyes with high myopic astigmatism.

Methods: In this prospective, randomized study on high myopic astigmatic eyes, 74 patients with similar refractive error received SMILE in one eye and FS-LASIK in the contralateral eye were enrolled. The central stromal reduction was calculated by preoperative and postoperative central stromal thickness (CST) measurements by the RTVue optical coherence tomography (OCT).

The emulsion gel composed of proteins and polysaccharides exhibits significant potential as a targeted delivery system for bioactives in the gastrointestinal tract. In this study, a composite emulsion was prepared by using sodium caseinate (NaCas) and gellan gum (GG), which was subsequently crosslinked with transglutaminase (TG), glucono-δ-lactone (GDL), and calcium ions (Ca) to form emulsion gels. The physicochemical properties of the NaCas/GG emulsion gels were characterized to verify the effects of zeaxanthin dipalmitate encapsulation and protection, and a possible mechanism was discussed.

The development of flexible ITO-free devices is crucial for the industrial advancement of organic photovoltaic (OPV) technology. Here, a novel ITO-free device architecture is proposed, and ITO-free OPV devices are realized on glass substrates with performance comparable to that of ITO-based devices. It is also demonstrated that the performance of ITO-free devices on polyethylene terephthalate (PET) substrates is limited due to the higher surface roughness of PET, leading to high voltage losses, low device quantum efficiency, and high device leakage current.
