Bioinspired "cage traps" for closed-loop lead management of perovskite solar cells under real-world contamination assessment.

Despite the remarkable progress made in perovskite solar cells, great concerns regarding potential Pb contamination risk and environmental vulnerability risks associated with perovskite solar cells pose a significant obstacle to their real-world commercialization. In this study, we took inspiration from the ensnaring prey behavior of spiders and chemical components in spider web to strategically implant a multifunctional mesoporous amino-grafted-carbon net into perovskite solar cells, creating a biomimetic cage traps that could effectively mitigate Pb leakage and shield the external invasion under extreme weather conditions. The synergistic Pb capturing mechanism in terms of chemical chelation and physical adsorption is in-depth explored.

Research progress of apelin in acute ischemic brain injury.

Acute ischemic brain injury is a cerebrovascular disease with high clinical incidence. An increasing number of preclinical evidence has verified the complex interaction between autophagy disorder and mitochondrial damage. Endoplasmic reticulum stress, oxidative stress and excessive neuroinflammation are the main mechanisms of the neural injury induced by acute cerebral ischemia-reperfusion injury.

Modulation of the EMT/MET Process by E-Cadherin in Airway Epithelia Stress Injury.

Persistent injury and the following improper repair in bronchial epithelial cells are involved in the pathogenesis of airway inflammation and airway remodeling of asthma. E-cadherin (ECAD) has been shown to be involved in airway epithelium injury repair, but its underlying mechanisms to this process is poorly understood. Here, we describe a previously undetected function of ECAD in regulating the balance of EMT and MET during injury repair.

A Neural Network Framework for Predicting the Tissue-of-Origin of 15 Common Cancer Types Based on RNA-Seq Data.

Sequencing-based identification of tumor tissue-of-origin (TOO) is critical for patients with cancer of unknown primary lesions. Even if the TOO of a tumor can be diagnosed by clinicopathological observation, reevaluations by computational methods can help avoid misdiagnosis. In this study, we developed a neural network (NN) framework using the expression of a 150-gene panel to infer the tumor TOO for 15 common solid tumor cancer types, including lung, breast, liver, colorectal, gastroesophageal, ovarian, cervical, endometrial, pancreatic, bladder, head and neck, thyroid, prostate, kidney, and brain cancers.

Nanographite-based fluorescent biosensor for detecting microRNA using duplex-specific nuclease-assisted recycling.

The development of a nanographite (NG)-based fluorescent biosensor for detecting microRNA (miRNA) is reported. Duplex-specific nuclease (DSN)-assisted signal amplification was key to its function. In the absence of a target, with the assistance of p-stacking interactions, the NG adsorbed the double carboxyfluorescein (FAM)-labelled probe (DFP) whose surface was perfectly complementary to miRNA, leading to quenching of FAM fluorescence.

Apelin/APJ system: A novel promising target for neurodegenerative diseases.

Neurodegenerative diseases, including Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD), are incurable diseases characterized by progressive loss of cognitive or motor function, which construct a serious threat to the life quality of aging populations and their life spans. Apelin is an endogenous ligand for the G protein-coupled receptor. Apelin is reported to be detected not only in the cardiovascular system but also in neurons of the central nervous system (CNS).

Apelin-13 Suppresses Neuroinflammation Against Cognitive Deficit in a Streptozotocin-Induced Rat Model of Alzheimer's Disease Through Activation of BDNF-TrkB Signaling Pathway.

Alzheimer's disease (AD), a progressive neurodegenerative disease characterized by impairments of cognitive function as a result of synaptic deficits and neuronal loss, is associated with inflammation. Apelin-13, a predominant neuropeptide with inhibiting effect on inflammation, has beneficial effects on cognition memory and neuronal damage. However, whether apelin-13 can protect neurons to ameliorate cognitive deficits in AD by inhibiting the inflammatory response remains largely unknown.

Meta-analysis of the association between MBOAT7 rs641738, TM6SF2 rs58542926 and nonalcoholic fatty liver disease susceptibility.

The membrane-bound O-acyltransferase 7 (MBOAT7) and transmembrane 6 superfamily member 2 (TM6SF2) are associated with lipid metabolism.

Programmable Target-Initiated DNAzyme Walker Walking along a Spatially Isolated and Highly Hybridizable Substrate Track on a Nanoparticle Surface.

Synthetic DNA machines that operate on the nanoscale three-dimensional (3D) track have attracted rapidly increasing interest because of their potential in biocomputing, drug delivery, and biosensing applications. Current nanoscale 3D DNA tracks are typically created by self-assembling thiolated oligonucleotides at gold nanoparticle (AuNP) surfaces via the strong Au-S chemistry. However, it remains challenging to accurately control the conformation and orientation of the 3D DNA track on AuNP surfaces and finely adjust the hybridization ability of the 3D track.

ITGB4 deficiency in bronchial epithelial cells directs airway inflammation and bipolar disorder-related behavior.

Background: Chronic persistent airway inflammation has been associated with the comorbidity of asthma and bipolar disorder (BD). However, the direct relevance between airway inflammation and BD-like psychiatric comorbidity is almost unknown. Integrin β4 (ITGB4) is downregulated on the airway epithelial of asthma patients, which might play a critical role in the parthenogenesis of airway inflammation.

Intracellular pH-Triggered, Targeted Drug Delivery to Cancer Cells by Multifunctional Envelope-Type Mesoporous Silica Nanocontainers.

In this work, a novel type of pH-sensitive multifunctional envelope-type mesoporous silica nanocontainers (SBDAPF) was constructed for targeted drug delivery to cancer cells. Poly(N-succinimidyl acrylate) was coated on the mesoporous silica nanoparticles surface via an acid-labile acetal linker to obtain the SBA particles for pH-triggered drug release. A model drug doxorubicin (DOX)-loaded SBA system (SBDA) showed low premature drug release at neutral pH and effective stimuli-responsive release under the acidic conditions.

Effect of nitric oxide synthase inhibitor L-NAME on fear extinction in rats: a task-dependent effect.

There is increasing evidence that nitric oxide may be involved in learning and memory. However, there remain comparatively few studies that have explored the relationship between nitric oxide signaling and fear extinction, an inhibitory learning model. In the present study, we tested the effects of nitric oxide synthase inhibitor l-NAME on three tone fear extinction tasks in rats.
