Post-modulation of layer-by-layer assemblies coordinated by a catalytic dose of fullerene derivatives without external fields.

Molecular assembly has attracted wide attention in chemistry, condensed physics, molecular electronics, and materials sciences. However, it remains a great challenge to perform post-modulation on the assembled structures without the aid of externally applied fields. Herein, we demonstrate a combined full-weak-bonded interaction and fullerene-derivative strategy and achieve the post-modulation of layer-by-layer assembly with a precision of 5.

Nanogenerators for gas sensing applications.

Gas sensors are now widely employed in many industries due to the rapid speed of industrialization and the growth of the Internet of Things. However, the wearability and mobility of traditional gas sensors are limited by their high reliance on external power sources. Nanogenerators (NGs) can compensate for their power source limitations when paired with gas sensors by transforming the environment's widely dispersed low-frequency energy into electrical energy, allowing for self-powered gas detection.

Nlnemo suppresses of BMP signaling in wing development of the brown planthopper, Nilaparvata lugens.

Nemo-like kinases (NLKs) integrate multiple signaling pathways and exhibit functional diversity in developmental processes, including the bone morphogenetic protein (BMP) pathway. However, their roles in insect wing development, particularly in hemimetabolous insects like the brown planthopper (Nilaparvata lugens), remain poorly understood. Here, we investigated the role of Nlnemo (Nlnmo), an NLK, in the wing development of N.

Adolescent administration of ketamine impairs excitatory synapse formation onto parvalbumin-positive GABAergic interneurons in mouse prefrontal cortex.

Ketamine, an N-methyl-d-aspartate (NMDA) receptor antagonist, induces deficits in cognition and information processing following chronic abuse. Adolescent ketamine misuse represents a significant global public health issue; however, the neurodevelopmental mechanisms underlying this phenomenon remain largely elusive. This study investigated the long-term effects of sub-chronic ketamine (Ket) administration on the medial prefrontal cortex (mPFC) and associated behaviors.

Clinical phenotype and genetic function analysis of a family with hypomyelinating leukodystrophy-7 caused by POLR3A mutation.

Substrate types and applications of MXene for surface-enhanced Raman spectroscopy.

Surface-enhanced Raman spectroscopy (SERS) has been widely used in the analysis of analytes because of its unique fingerprint characteristics, high sensitivity, and fast detection response. MXene is widely used in SERS studies among the various substrates due to its ultra-high chemical stability, excellent conductivity, hydrophilicity, and low fabrication cost. This mini-review summarizes MXene's research in the SERS field from two aspects.

A valuable subarachnoid space named the occipito-atlantal cistern.

The cisterna magna has been defined as the space between the inferior margin of the cerebellar vermis to the level of the foramen magnum, while an enlarged dorsal subarachnoid space at the occipito-cervical junction extending from the foramen magnum to the upper border of the axis (C2) is still ignored. Recently, the myodural bridge complex is proved to drive the cerebral spinal fluid flowing via this region, we therefore introduce the "occipito-atlantal cistern (OAC)" to better describe the subarachnoid space and provide a detailed rationale. The present study utilized several methods, including MRI, gross anatomical dissection, P45 sheet plastination, and three-dimensional visualization.

Heat shock protein 70 (HSP70) is a stress protein with neuroprotective activity, but the potential protective mechanisms are not fully understood.

Methods And Results: Here, we investigated the effects of HSP70 regulators in a cellular TBI model induced by traumatic neuronal injury (TNI) and glutamate treatment.

A spatiotemporal barrier formed by Follistatin is required for left-right patterning.

How left-right (LR) asymmetry emerges in a patterning field along the anterior-posterior axis remains an unresolved problem in developmental biology. Left-biased Nodal emanating from the LR organizer propagates from posterior to anterior (PA) and establishes the LR pattern of the whole embryo. However, little is known about the regulatory mechanism of the PA spread of Nodal and its asymmetric activation in the forebrain.
