Stacking ferroelectricity in two-dimensional van der Waals materials.

Miniaturization of ferroelectrics for technological applications has proven challenging due to the suppression of electric polarization caused by increasing depolarization fields as material thickness decreases. The emergence of ferroelectricity in two-dimensional (2D) van der Waals (vdW) materials offers a potential solution to this challenge, prompting significant research efforts over the past decade. While intrinsic 2D vdW ferroelectrics are scarce, polar stacking provides a more general approach to introducing ferroelectricity in these materials.

Integrated course on ocular anatomy for ophthalmology clerkship.

Background: Obtaining a full understanding of the anatomical structure of the eyeball and the contents within the eye plays a crucial role in learning eye diseases. However, it can be challenging for beginners to quickly learn, memorize, and apply this anatomical knowledge. To improve the teaching of ocular anatomy and help students overcome learning difficulties in ophthalmology clerkship, Zhongshan Ophthalmic Center developed an integrated ocular anatomy course comprising three main components: 'online preview,' 'lecture,' and 'wetlab dissection'.

How i do it: full-endoscopic transsacral approach for the treatment of extraforaminal L5/S1 disc herniation.

Background: For L5/S1 extraforaminal disc herniation, how to efficiently expose the herniated nucleus pulposus and reduce facet joint damage remain to be explored.

Methods: Lumbar discectomy was performed using a full-endoscopic transsacral approach, in which sacral ala and extraforaminal ligament were partially resected to expose the L5/S1 intervertebral disc. Methylene blue was used for disc staining, and the herniated nucleus pulposus was excised through the annular tear.

Haplotype-Resolved Genotyping and Association Analysis of 1,020 β-Thalassemia Patients by Targeted Long-Read Sequencing.

Despite the well-documented mutation spectra of β-thalassemia, the genetic variants and haplotypes of globin gene clusters modulating its clinical heterogeneity remain incompletely illustrated. Here, a targeted long-read sequencing (T-LRS) is demonstrated to capture 20 genes/loci in 1,020 β-thalassemia patients. This panel permits not only identification of thalassemia mutations at 100% of sensitivity and specificity, but also detection of rare structural variants (SVs) and single nucleotide variants (SNVs) in modifier genes/loci.

Application of mobile internet management in the continuing care of patients after radical prostatectomy.

Prostate cancer, a common malignancy in older men, often requires laparoscopic radical prostatectomy, considered the gold standard treatment. However, postoperative complications can significantly impact quality of life and psychological well-being. The emergence of mobile internet health management offers a promising approach for accessible and effective post-discharge care.

In vivo adenine base editing ameliorates Rho-associated autosomal dominant retinitis pigmentosa.

Mutations in the Rhodopsin (RHO) gene are the main cause of autosomal dominant retinitis pigmentosa (adRP), 84% of which are pathogenic gain-of-function point mutations. Treatment strategies for adRP typically involve silencing or ablating the pathogenic allele, while normal RHO protein replacement has no meaningful therapeutic benefit. Here, we present an adenine base editor (ABE)-mediated therapeutic approach for adRP caused by RHO point mutations in vivo.

Disruption of the gut microbiota-inflammation-brain axis in unmedicated bipolar disorder II depression.

The relationships of the gut microbiota-inflammation-brain axis in depressive bipolar disorder (BD) remains under-elaborated. Sixty-five unmedicated depressive patients with BD II and 58 controls (HCs) were prospectively enrolled. Resting-state functional MRI data of static and dynamic amplitude of low-frequency fluctuation (ALFF) was measured, and abnormal ALFF masks were subsequently set as regions of interest to calculate whole-brain static functional connectivity (sFC) and dynamic functional connectivity (dFC).

Autophagy promotes p72 degradation and capsid disassembly during the early phase of African swine fever virus infection.

During viral infections, autophagy functions as a cell-intrinsic defense mechanism by facilitating the delivery of virions or viral components to the endosomal/lysosomal pathway for degradation. In this study, we report that internalized African swine fever virus (ASFV) virions enter autolysosomes during the early phase of viral infection. Autophagy selectively targets the major capsid protein p72 within the ASFV virion.

Investigation of Buckling Behaviors in Carbon Nanorings Using the Chebyshev-Ritz Method.

Carbon nanorings (CNRs) serve as an ideal quantum system for novel electronic and magnetic properties. Although extensive theoretical studies utilizing molecular dynamics (MD) simulations have investigated the formation and structural characteristics of CNRs, systematically analyzing their properties across various toric sizes remains challenging due to the inherent complexity of this system. In this study, we introduce a novel finite element method, the Chebyshev-Ritz method, as an alternative approach to investigating the structural properties of CNRs.
