Tolerogenic dendritic cells with professional antigen presentation via major histocompatibility complex molecules, co-stimulatory molecules (CD80/86), and interleukin 10 production have attracted significant attention as cellular therapies for autoimmune, allergic, and graft-versus-host diseases. In this study, we developed a cell culture dish equipped with polycation-porphyrin-conjugate-immobilized glass (PA-HP-G) to stimulate immature murine dendritic cell (iDCs). Upon irradiation with a red light at 635 nm toward the PA-HP-G surface, singlet oxygen was generated by the immobilized porphyrins on the PA-HP-G surface.

Article Synopsis
  • The study aimed to compare the clinical, radiological, and laboratory features of newly diagnosed smear-positive pulmonary tuberculosis in elderly patients (65+) versus younger patients in Vietnam.
  • Out of 183 patients analyzed, those aged 65 and older showed differences in symptoms and X-ray findings, with younger patients more likely to experience night sweats and cavitation lesions, while elderly patients experienced more muscle/joint pain and pulmonary fibrosis.
  • The research highlights the need for age-specific considerations in diagnosing and treating tuberculosis, indicating that tailored approaches could improve patient outcomes based on age-related differences.

  • The study compares primary closure versus T-tube drainage methods after laparoscopic common bile duct exploration (LCBDE) in elderly patients (≥65 years).
  • Data collected from two Vietnamese hospitals was analyzed, revealing that primary closure resulted in shorter operating times and hospital stays compared to T-tube drainage.
  • Both methods had similar long-term stone recurrence rates, suggesting that primary closure is a safe and effective option for elderly patients with biliary issues.

This study explores the synthesis, characterization, and photocatalytic properties of bismuth metal-organic framework (Bi-MOF) nanorods and their derivatives such as Ag/Bi-MOF and Ag/BiO. Bi-MOF nanorods exhibit significant photocatalytic activity under visible light, with the addition of silver (Ag) enhancing electron-hole pair separation and reducing their recombination. This leads to improved photocatalytic performance, particularly in the degradation of organic pollutants such as Rhodamine B (RhB) and Methylene Blue (MB).

Article Synopsis
  • The internal environment of cells features diverse organelles, including biomolecular condensates, which are unique, membrane-less compartments enriched in specific proteins and nucleic acids.
  • The presence of ion concentration gradients within cells creates non-equilibrium conditions that enhance the transport of biomolecules and promote the formation of these condensates.
  • Using a microfluidic platform, researchers showed that these ion gradients accelerate biomolecule movement, allowing localized formation of condensates and increasing their motility and lifespan.

Background: Plasmodium falciparum parasitaemia during pregnancy causes maternal, fetal, and infant mortality. Poor pregnancy outcomes are related to blood-stage parasite sequestration and the ensuing inflammatory response in the placenta, which decreases over successive pregnancies. A radiation-attenuated, non-replicating, whole-organism vaccine based on P falciparum sporozoites (PfSPZ Vaccine) has shown efficacy at preventing infection in African adults.

Article Synopsis
  • Current biofabrication methods struggle to mimic the complex relationships between the shapes and functions of engineered tissues due to limitations in hydrogels used.
  • This study introduces a new microfluidics platform that allows for precise control over the structure and composition of hydrogels through a two-step process, enabling the creation of unique shapes, sizes, and stiffness patterns.
  • The platform successfully encapsulates stem cells and demonstrates how variations in stiffness can influence cell behavior, with potential implications for breast cancer metastasis based on stiffness gradients.

Although numerous AI algorithms have been published, the relatively small number of algorithms used clinically is partly due to the difficulty of implementing AI seamlessly into the clinical workflow for radiologists and for their healthcare enterprise. The authors developed an AI orchestrator to facilitate the deployment and use of AI tools in a large multi-site university healthcare system and used it to conduct opportunistic screening for hepatic steatosis. During the 60-day study period, 991 abdominal CTs were processed at multiple different physical locations with an average turnaround time of 2.

The catalytic application of 3-(4-sulfobutyl)-1-imidazole-3-ium chloride immobilized on activated silica gel (SiO-Imi-SOH) for the production of 5-hydroxymethylfurfural is described here for the first time. This material was synthesized using a three-step method involving the grafting of chloropropyl groups onto activated silica gel, the substitution of zwitterions, and the acidification of zwitterions to form silica-supported ionic liquid. The successful immobilization of the IL on silica gel was confirmed through energy-dispersive X-ray (EDX) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and elemental mapping.
