Article Synopsis
  • Recent research has identified unconventional antiferromagnets that allow for spin splitting of electronic states, which could significantly advance antiferromagnetic spintronics due to their unique magnetic symmetries.
  • * The study focuses on CrSb, a promising metallic antiferromagnet with a high Néel temperature of 703 K, using techniques like angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) to analyze its electronic structure.
  • * Findings disclose a notable, k-dependent spin splitting of up to 0.8 eV, surpassing traditional spin-orbit coupling effects, suggesting CrSb could contribute to the development of efficient spintronic devices that work at room temperature.

Article Synopsis
  • The kagome spin ice can exhibit frustrated magnetic excitations when local spins are flipped, which can be studied using scanning tunneling microscopy (STM).
  • Applying this technique to the kagome metal HoAgGe, distinct dips in the local tunneling spectrum indicate a strong correlation with the spin ice's magnetic properties, disappearing above the spin ice formation temperature.
  • A two-level spin-flip model is proposed to explain these tunneling dips, highlighting the role of spin-orbit coupling in the emergent excitations of spin ice magnetism in this material.

Spatial, momentum and energy separation of electronic spins in condensed-matter systems guides the development of new devices in which spin-polarized current is generated and manipulated. Recent attention on a set of previously overlooked symmetry operations in magnetic materials leads to the emergence of a new type of spin splitting, enabling giant and momentum-dependent spin polarization of energy bands on selected antiferromagnets. Despite the ever-growing theoretical predictions, the direct spectroscopic proof of such spin splitting is still lacking.

The century-long development of surface sciences has witnessed the discoveries of a variety of quantum states. In the recently proposed "obstructed atomic insulators", symmetric charges are pinned at virtual sites where no real atoms reside. The cleavage through these sites could lead to a set of obstructed surface states with partial electronic occupation.

Oral infections are common among individuals of all ages and can activate local and systemic inflammation. The inflammatory response plays an important role in atherosclerosis. An increasing number of studies have reported an association between oral pathogen infection and atherosclerotic coronary heart disease.

Article Synopsis
  • * Lipophagy is a process where autophagosomes capture and deliver fat stored in lipid droplets to lysosomes for degradation, initially identified in liver cells and crucial for understanding how lipids impact cell function and disease.
  • * The review explores how PCSK9 influences lipid breakdown through the lipophagy pathway and suggests targeting lipophagy could be a promising approach for treating atherosclerosis.

Hesperetin, an abundant bioactive component of citrus fruits, is poorly water-soluble, resulting in low oral bioavailability. We developed new formulations to improve the water solubility, antioxidant activity, and oral absorption of hesperetin. Two nano-based formulations were developed, namely hesperetin-TPGS (D-α-tocopheryl polyethylene glycol 1000 succinate) micelles and hesperetin-phosphatidylcholine (PC) complexes.

Many pharmacokinetic studies of paclitaxel formulations with or without Cremophor (CrEL) have been performed on experimental animals. However, limited studies describe the different pharmacokinetic behaviors of paclitaxel in animals. The different distribution of drug in blood fractions may have great effect on its pharmacokinetic behaviors.

The objectives of this study were to define the pharmacokinetics of recombinant human interleukin-1 receptor antagonist (rhIL-1ra) and its effects on allergic asthma, cell adhesion molecules, and upper respiratory tract following non-parenteral administration in animals. Pharmacokinetics and immunomodulating effects of rhIL-1ra were investigated in Sprague-Dawley rats and asthmatic guinea pigs, respectively. Effects on the upper respiratory tract following the applications of rhIL-1ra were investigated on the ex vivo nasal mucosa of Sprague-Dawley rats and in situ in the upper palate of Chinese toads.
