Stereochemical Activity and Luminescence Mechanism in (CHN)SnCl Doped with ns Metal Ions.

Metal halide luminescent materials, particularly those doped with ns ions, exhibit exceptional optical properties. However, the luminescent mechanisms associated with the stereochemical activity of lone-pair electrons remain insufficiently explored. In this study, zero-dimensional (0D) tin-based halide (CHN)SnCl is utilized as a model system to investigate the effects of lattice distortion and lone-pair electron expression on fluorescence emission characteristics by doping with 6s and 5s ions.

Charge-redistributed RuNi/MoN heterojunction enables efficient hydrogen evolution in a wide pH range.

Electrocatalytic hydrogen production offers a promising solution to address current energy depletion. Herein, a RuNi/MoN heterostructure on carbon cloth (CC), RuNi/MoN@CC, was successfully constructed using a simple method, allowing for dual regulation of morphology and electronic structure. Under the influence of Ni, the in-situ generated MoN inherits the morphology of the NiMoO precursor, presenting a nanowire morphology, which is favorable for increasing electrochemical active area.

A brainstem circuit amplifies aversion.

Dynamic gain control of aversive signals enables adaptive behavioral responses. Although the role of amygdalar circuits in aversive processing is well established, the neural pathway for amplifying aversion remains elusive. Here, we show that the brainstem circuit linking the interpeduncular nucleus (IPN) with the nucleus incertus (NI) amplifies aversion and promotes avoidant behaviors.

Silencing endomucin in bone marrow sinusoids improves hematopoietic stem and progenitor cell homing during transplantation.

Efficient homing of infused hematopoietic stem and progenitor cells (HSPCs) into the bone marrow (BM) is the prerequisite for successful hematopoietic stem cell transplantation. However, only a small part of infused HSPCs find their way to the BM niche. A better understanding of the mechanisms that facilitate HSPC homing will help to develop strategies to improve the initial HSPC engraftment and subsequent hematopoietic regeneration.

This study aimed at exploring the potential involvement of ciprofol on ferroptosis-associated CIRI and subsequent neurological deficits in the mouse model of transient cerebral ischemia and reperfusion.

Targeted approaches to delineate neuronal morphology during early development.

Understanding the developmental changes that affect neurons is a key step in exploring the assembly and maturation of neural circuits in the brain. For decades, researchers have used a number of labeling techniques to visualize neuronal morphology at different stages of development. However, the efficiency and accuracy of neuronal labeling technologies are limited by the complexity and fragility of neonatal brains.

Allosterically inhibited PFKL via prostaglandin E2 withholds glucose metabolism and ovarian cancer invasiveness.

Metastasis is the leading cause of high ovarian-cancer-related mortality worldwide. Three major processes constitute the whole metastatic cascade: invasion, intravasation, and extravasation. Tumor cells often reprogram their metabolism to gain advantages in proliferation and survival.

WDR77 inhibits prion-like aggregation of MAVS to limit antiviral innate immune response.

RIG-I-MAVS signaling pathway plays a crucial role in defending against pathogen infection and maintaining immune balance. Upon detecting viral RNA, RIG-I triggers the formation of prion-like aggregates of the adaptor protein MAVS, which then activates the innate antiviral immune response. However, the mechanisms that regulate the aggregation of MAVS are not yet fully understood.

Tanshinone IIA analogue 15a inhibits NLRP3-mediated inflammation by activating mitophagy in macrophages to alleviate acute tubular necrosis.

Background: Acute tubular necrosis (ATN) is a common type of acute renal failure. Recent studies have shown that NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome-mediated pyroptosis in macrophages plays a crucial role in the progression of ATN. Previously, we synthesized an anti-inflammatory compound 15a based on Tanshinone IIA (Tan IIA).

Acetamide- or Formamide-Assisted In Situ Approach to Carbon-Rich or Nitrogen-Deficient Graphitic Carbon Nitride for Notably Enhanced Visible-Light Photocatalytic Redox Performance.

Acetamide- or formamide-assisted in situ strategy is designed to synthesize carbon atom self-doped g-C N (AHCN ) or nitrogen vacancy-modified g-C N (FHCN ). Different from the direct copolymerization route that suffers from the problem of mismatched physical properties of acetamide (or formamide) with urea, the synthesis of AHCN (or FHCN ) starts from a crucial preorganization step of acetamide (or formamide) with urea via freeze drying-hydrothermal treatment so that the chemical structures as well as C-doping level in AHCN and N-vacancy concentration in FHCN can be precisely regulated. By using various structural characterization methods, well-defined AHCN and FHCN structures are proposed.

Dissection of the long-range projections of specific neurons at the synaptic level in the whole mouse brain.

Through synaptic connections, long-range circuits transmit information among neurons and connect different brain regions to form functional motifs and execute specific functions. Tracing the synaptic distribution of specific neurons requires submicron-level resolution information. However, it is a great challenge to map the synaptic terminals completely because these fine structures span multiple regions, even in the whole brain.

Liposomes trigger bone marrow niche macrophage "foam" cell formation and affect hematopoiesis in mice.

Liposomes are the most widely used nanocarrier platform for the delivery of therapeutic and diagnostic agents, and a number of liposomes have been approved for use in clinical practice. After systemic administration, most liposomes are cleared by macrophages in the mononuclear phagocyte system, such as the liver and bone marrow (BM). However, the majority of studies have focused on investigating the therapeutic results of liposomal drugs, and too few studies have evaluated the potential side effects of empty nanocarriers on the functions of macrophages in the mononuclear phagocyte system.
