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.

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.

Article Synopsis
  • Antisense transcript of the B-cell translocation gene 3 (ASBEL) is a non-coding RNA that is involved in various biological processes, but its role in pancreatic ductal adenocarcinoma (PDAC) was not fully understood before this study.
  • The research conducted both cell and animal experiments to demonstrate that ASBEL is crucial for the tumor development in PDAC by targeting the gene BTG3.
  • Findings showed that ASBEL is more highly expressed in PDAC tissues than in normal tissues, and it promotes cancer cell growth, migration, and invasion, suggesting its potential as a biomarker for PDAC treatment.

Background: Synchronous primary cancers (SPCs) have become increasingly frequent over the past decade. However, the coexistence of duodenal papillary and gallbladder cancers is rare, and such cases have not been previously reported in the English literature. Here, we describe an SPC case with duodenal papilla and gallbladder cancers and its diagnosis and successful management.

Background: Spontaneous bladder rupture is relatively rare, and common causes of spontaneous bladder rupture include bladder diverticulum, neurogenic bladder dysfunction, gonorrhea infection, pelvic radiotherapy, . Urinary bladder perforation caused by urinary catheterization mostly occurs during the intubation process.

Case Summary: Here, we describe an 83-year-old male who was admitted with 26 h of middle and upper abdominal pain and a history of long-term catheterization.

Background: Duplication of the appendix is an infrequent congenital malformation with a complex classification. The horseshoe appendix is a subtype of the duplex appendix and is rarely reported in the literature. Endometriosis is a common gynecological disease that rarely occurs in the appendix.

In the original version of this Article, an incorrect sample size was provided for the number of relict species (443 instead of 442) and the number of relict forests (423 instead of 422). These errors have been corrected in both the PDF and HTML versions of the Article.

Today East Asia harbors many "relict" plant species whose ranges were much larger during the Paleogene-Neogene and earlier. The ecological and climatic conditions suitable for these relict species have not been identified. Here, we map the abundance and distribution patterns of relict species, showing high abundance in the humid subtropical/warm-temperate forest regions.

Objective: To understand the dietary nutrients among rural stranded children.

Methods: 2551 children aged 2 to 7, including 1278 stranded children in the rural areas and another 127 children served as controls were selected, using multistage stratified cluster random sampling. Dietary survey was performed with three-day weighing dietary method and questionnaire on food intake.

Objective: To understand the status on care and nutrition of children living in the rural areas (so called 'left-behind' children) while their parents were seeking for jobs in the urban areas.

Methods: Cross-sectional study was employed in this investigation. The group of 'left-behind' children (n = 774) and the comparison group (n = 774) were identified.

Habitat heterogeneity plays a key role in the dynamics and structures of communities. In this article, a two-species metapopulation model that includes local competitive dynamics is analyzed to study the population dynamics of two competing species in spatially structured habitats. When local stochastic extinction can be ignored, there are, as in Lotka-Volterra equations, four outcomes of interspecific competition in this model.
