PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility

Advanced Science, EarlyView.
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses

Advanced Science, EarlyView.
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

Role of ultrasound and color Doppler in diagnosis of ectopic pregnancy and to differentiate from corpus luteum cyst of pregnancy

Asian Journal of Medical Sciences
Background: Ectopic pregnancy is the leading cause of direct maternal deaths. Ectopic pregnancy and corpus luteum cyst are two most common differential diagnoses in a patient with urine pregnancy test (UPT) positive and no sonographic evidence of ...

Dose‐Dependent Reprogramming of Chromatin Accessibility by SOX4 Drives the Transcriptional Response to Iron Overload

Advanced Science, EarlyView.
This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

A case report of heterochronic presentation of a bilateral tubal pregnancy

Clinical Case Reports, 2023
Key Clinical Message This paper highlights that diagnosis and treatment of one ectopic pregnancy does not rule out the happening of a second ectopic pregnancy in the same patient concurrently, especially if the patient has rising β‐hCG and persistent ...

Temporal Interference Stimulation Enhances Neural Regeneration

Advanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.
