"Hot quadrate lobe sign" refers to visualization of caudate lobe of liver due to excess accumulation of radiotracer secondary to superior vena cava obstruction. Collateral channels are formed between thoracic and mediastinal vessels; internal mammary through the paraumbilical vessels which drain blood to the left portal vein and into the caudate lobe of liver. It was first described on Tc99-m sulfur colloid scan.

Developing new conductive primers to ensure electrostatic spraying is crucial in response to the call for lightweight production of new energy vehicles. We report a stabilized material, Fe-T/G, of Fe-doped TiO composite graphene synthesized by a simple hydrothermal and electrostatic self-assembly method. The resistivity decreases from 0.

The formation and growth of lithium dendrites is an ever-present and urgent problem in lithium-ion batteries (LIBs). At the same time, the low melting point of commercial polyolefin separators may lead to safety issues during application. On this basis, in this work, poly (m-phenylene isophthalamide) (PMIA)/Zr-based metal-organic framework (NH-UiO-66) composite separator was prepared by non-solvent induced phase separation (NIPS).

Article Synopsis
- Mucus consists of mucin polymers linked by disulfide bonds, and in muco-obstructive diseases, these bonds increase mucus viscosity and stiffness.
- Reducing agents that can break these disulfide bonds may help restore healthy mucus flow by treating abnormal mucus properties.
- The study compares the effectiveness of three reducing agents using a rheological assay to analyze how each agent affects the properties of a mucus-like hydrogel, highlighting their different degradation mechanisms and potential impact on drug delivery and treatment.
