METTL7A Downregulation Drives SLC1A5‐Mediated Glutamine Competition to Promote Tumor Proliferation and Suppress CD8+ T Cell Immunity in Gastric Cancer

Advanced Science, EarlyView.
GC cells enhance glutamine accumulation by upregulating SLC1A5 expression. This upregulation not only boosts GC cell proliferation, but also outcompetes CD8+ T cells for glutamine and suppresses their antitumor immunity. Mechanistically, METTL7A deficiency in GC induces SLC1A5 overexpression via an m6A‐dependent pathway and N‐glycosylation ...

Linear complexity of two classes of optimal sets frequency-hopping sequences

Tongxin xuebao, 2012
By using a type of permutation polynomials which were different from power permutations,the two classes of frequency-hopping sequence sets with low linear complexity was transformed into the ones with high linear complexity.The exact values of linear ...

A Microcapsule‐Integrated smRandom‐seq Platform Enables Fixation‐Free Single Microbe RNA Sequencing

Advanced Science, EarlyView.
We developed a microcapsule‐integrated high‐throughput fixation‐free single‐microbe RNA‐seq workflow in which microbes are encapsulated in aqueous two‐phase microcapsules for physical confinement of nucleic acids. This platform enables co‐encapsulation with barcoded beads for sequencing and reveals that fixation‐free processing enhances transcriptomic ...

Securing RSA Algorithm Against Side Channel Attacks

Telecom
RSA’s modular exponentiation is the basic operation in public key infrastructure and is naturally the target of side-channel attacks. In this work we propose two algorithms that defeat side-channel attacks: Paired Permutation Exponentiation (PPE) and ...

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

TumorGANet: A Transfer Learning and Generative Adversarial Network- Based Data Augmentation Model for Brain Tumor Classification

IEEE Access
Diagnosing brain tumors using magnetic resonance imaging (MRI) presents significant challenges due to the complexities of segmentation and the variability in tumor characteristics. To address the limitations inherent in traditional methods, this research

On the theoretical bounds of FHS set with periodic partial Hamming correlation

Electronics Letters, 2016
The theoretical bounds are often used to measure the performance of frequency‐hopping sequences (FHSs) in FH multiple access systems. For the periodic partial Hamming correlation properties of FHS sets, two kinds of theoretical lower bound and their improved version were proposed.

Self‐Amplified Activatable Fluorescent Probe for Early Diagnosis of Acute Kidney Injury and High‐Throughput Screening of Natural Protectants

Advanced Science, EarlyView.
The PS‐QRC nanoprobe employs L‐serine as a targeting ligand for kidney injury molecule‐1 (KIM‐1) to achieve accumulation in injured renal tissues. Upon activation by reactive oxygen species (ROS), it undergoes a self‐amplifying cascade to release fluorophores for near‐infrared fluorescence (NIRF) imaging, enabling ultra‐early diagnosis of acute kidney ...

Targeting the PHB2–ACSL3 Lipid‐Remodeling Axis Overcomes Cisplatin Resistance by Restoring Ferroptosis in Gastric Cancer

Advanced Science, EarlyView.
ABSTRACT Platinum‐based chemotherapy resistance remains a major obstacle in gastric cancer (GC) treatment. Through integrated transcriptomic profiling of cisplatin‐resistant xenografts and pharmacogenomic interrogation of the NCI‐60 dataset, we identified Prohibitin‐2 (PHB2) as a previously unrecognized determinant of chemoresistance.
