A shift toward a T cell exhaustion phenotype is associated with the upregulation of expression of programmed cell death protein 1 (PD-1) on T lymphocytes in patients with malignant solid tumors. The interaction between PD-1 and programmed death-ligand 1 (PD-L1) inhibits PD-1 T lymphocyte function, impacting their anti-tumor immune activity. Immune checkpoint inhibitors targeting PD-1/PD-L1 have revolutionized the treatment of various solid malignancies, improving therapeutic efficacy and survival outcomes.

The intensive interest in expanded porphyrins can be attributed to their appealing photoelectric and coordination behavior. In this work, an N-confused heptaphyrin 1 was synthesized by an acid-catalyzed [3+4] condensation reaction. The introduction of an N-confused pyrrolic unit into the heptaphyrin macrocycle led to the formation of a figure-eight-like conformation with nonsymmetrical "NNNN" and "NNNC" coordination cavities employable for bimetallic coordination.

Poly (vinyl alcohol) (PVA) hydrogel showed potential applications in bioengineering and wearable sensors fields. It is still a huge challenge to prepare highly adhesive yet strong poly (vinyl alcohol) hydrogel with good biocompatibility. Herein, we prepared a highly self-adhesive and strong poly (vinyl alcohol)/tannic acid@cellulose nanocrystals (PVA/TA@CNCs) composite hydrogel using TA@CNCs as functional nanofiller via facile freezing-thawing method.

Among other photovoltaic techniques including perovskite solar cells and organic solar cells, dye-sensitized solar cells (DSSCs) are considered to be a potential alternative to conventional silicon solar cells. Porphyrins are promising dyes with the properties of easy modification and superior light-harvesting capability. However, porphyrin dyes still suffer from a number of unfavorable aspects, which need to be addressed in order to improve the photovoltaic performance.

This article presents a haptic actuator made of silicone rubber to provide both passive and active haptic forces for catheter simulations. The haptic actuator has a torus outer shape with an ellipse-shaped inside chamber which is actuated by hydraulic pressure. Expansion of the chamber by providing positive pressure can squeeze the inside passage to resist the catheter traveling through.

Purpose: We aim to establish diagnostic thresholds of sarcopenia and myosteatosis based on CT measurements, and to validate their prognostic value in a large cohort of kidney transplant recipients.

Methods: Local healthy population with abdominal CT between 2010 and 2022, and patients underwent kidney transplantation between 2015 and 2019 at our center were retrospectively included. The skeletal muscle index and muscle attenuation of abdominal muscles were calculated based on CT image at the middle of the third lumbar vertebra.

In practical industrial-scale paddy drying production, manual empirical operation is still widely used for process control. This often leads to poor uniformity in the moisture content distribution of discharged grains, affecting product quality. Model Predictive Control (MPC) is considered the most effective control method for paddy drying, but its implementation in industrial-scale drying is hindered by its high computational cost.

Thiahexaphyrinone and thia-dipyrrin-appended corrorin have been synthesized. Surprisingly, further oxidation of compound with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) in dichloromethane afforded dimer with two molecules of compound linked at the α-carbon atoms of the thienyl units. Treatment of compound with DDQ in MeOH and SnCl in tetrahydrofuran/HO afforded the dimethoxy-attached dimer and hydrogenated dihydroxy-attached dimer , respectively.

Pain is a widespread non-motor symptom that presents significant treatment challenges in patients with Parkinson's disease (PD). Safinamide, a new drug recently introduced for PD treatment, has demonstrated analgesic effects on pain in PD patients, though the underlying mechanisms remain unclear. To investigate the analgesic and anti-PD effect of safinamide, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD mouse model was used, and rasagiline as positive control on motor symptoms.

Article Synopsis
  • Researchers designed new porphyrin dyes to improve dye-sensitized solar cells (DSSCs), focusing on a specific dye that includes a phenothiazine donor and a benzo 12-crown-4 (BCE) unit.
  • The new dyes produced higher open-circuit voltage (765-779 mV) compared to the previous dye (755 mV) due to better lithium binding, which prevents charge loss in the solar cells.
  • Incorporating the BCE unit resulted in greater dye loading and a peak power conversion efficiency (PCE) of 11.1%, with a combination of a concerted companion dye further boosting efficiency to 12.1%.
