The clinical implications of extrachromosomal DNA (ecDNA) in cancer therapy remain largely elusive. Here, we present a comprehensive analysis of ecDNA amplification spectra and their association with clinical and molecular features in multiple cohorts comprising over 13,000 pan-cancer patients. Using our developed computational framework, GCAP, and validating it with multifaceted approaches, we reveal a consistent pan-cancer pattern of mutual exclusivity between ecDNA amplification and microsatellite instability (MSI).

Herein, we found that covalent rigidification of the aggregation-induced emission luminogens (AIEgens) TABE (TABE = tetra-(4-aldehyde-(1,1-biphenyl))ethylene) into covalent organic framework nanosheets (TABE-PZ-CON, PZ = piperazine) could result in stronger ECL emission than those of TABE aggregates and TABE monomers. We termed the interesting phenomenon "covalent rigidification-triggered electrochemiluminescence (CRT-ECL) enhancement".

Background: Littoral cell angioma (LCA) is a rare benign vascular tumor of the spleen. Given its rarity, standard diagnostic and therapeutic recommendations have yet to be developed for reported cases. Splenectomy is the only method of obtaining a pathological diagnosis and providing treatment to obtain a favorable prognosis.

Objective: Glial cells are involved in the analgesic effect of electroacupuncture (EA) in rats with chronic neurological pain. The objective of this study was to observe the role of neuronal-glial interaction and glutamate (Glu) transporters in EA-induced acute neck pain relief in rats.
Materials And Methods: Male rats were placed into the following five groups: control, model, EA Futu (LI18), EA Hegu (LI4)-Neiguan (PC6), and EA Zusanli (ST36)-Yanglingquan (GB34).
Pro-inflammatory factors may be associated with abnormalities in functional brain networks, which may be a mechanism in the pathogenesis of major depressive disorder (MDD). Electroencephalogram (EEG) microstates reflect the functioning of brain networks. However, the relationship between pro-inflammatory factors and the microstate abnormalities in patients with MDD is poorly understood.

Methods: A total of 48 young SD rats were randomly divided into control (=10), model (=9), taVNS (=9), subdiaphragmatic vagus nerve stimulation (SDVNS, =9) and sham SDVNS (=7) groups. The FD model was established by gavage of 0.
To explore the role of atorvastatin in regulating intraocular pressure (IOP) in glaucoma , and to investigate its related molecular pathway , an ocular hypertension model was generated by intravitreal injection of an adenoviral vector encoding transforming growth factor (TGF)‑β2 in the right eye of BALB/cJ mice, while the left was treated with an empty control adenovirus. To determine its anti‑intraocular hypertension role, these induced hyper‑IOP mice were gavaged with atorvastatin (20 mg/kg/day). Furthermore, extracellular matrix (ECM) factors were examined in the primary human trabecular meshwork (HTM) cells followed atorvastatin (0~200 µM) treatment .

To address this shortcoming, we used 2,3,6,7,10,11-hexaaminotriphenylene (HATP) and 2,3,6,7,10,11-hexahydroxytriphenylene (HHTP) to synthesize a conductive COF (HHTP-HATP-COF, conductivity = 3.11 × 10 S m).

Methods: A total of 48 male SD rats were randomized into a sham-operation group, a model group, a transcutaneous auricular non-vagus nerve stimulation (tnVNS) group and a taVNS group, with 12 rats in each group. The suture-occluded method was adopted to prepare MCAO rat model.
Background: The hypothalamus-pituitary-adrenal axis is the most important endocrine system to control irritability response. Functional dyspepsia (FD) is closely related to irritability. This study aimed to preliminarily explore the corticotropin-releasing factor (CRF) mechanism of auricular vagus nerve stimulation (aVNS) for FD model rats.

Type 2 diabetes mellitus (T2DM) rat models were received intravitreal injection of antagomir NC (negative control), miR-93-5p antagomir, miR-93-5p agomir and/or recombinant Sirt1, followed by observation of pathological changes in retina via HE staining.
A pyrene-based sp carbon-conjugated covalent organic framework (COF) nanosheet (Py-spc-CON) with strong and stable electrochemiluminescence (ECL) emission was constructed by C═C polycondensation of tetrakis(4-formylphenyl)pyrene (TFPPy) and 2,2'-(1,4-phenylene)diacetonitrile, which was employed as a highly efficient ECL emitter to fabricate an ECL biosensor for the first time. The Py-spc-CON exhibited higher ECL intensity and efficiency than those of TFPPy, bulk Py-spc-COF, and imine-linked pyrene COF, not only because the pyrene luminophores and aggregation-induced emissive luminogens (cyano-substituted phenylenevinylene) were topologically linked into Py-spc-CON, which greatly increased the immobilization amount of luminophores and decreased the aggregation-caused quenching effect and nonradiative transition but also because the porous ultrathin structure of Py-spc-CON effectively shortened transport distances of an electron, ion, and co-reactant (SO), which made more ECL luminophores be activated and thus efficiently increased the utilization ratio of luminophores. More interestingly, when BuNPF was introduced into the Py-spc-CON/SO system as a co-reaction accelerator, the ECL signal of Py-spc-CON was further amplified.

Especially in the past century or more, the relevant theoretical and applied research on the ear has greatly promoted the development of ear therapy, and finally the concept of transcutaneous auricular vagus nerve stimulation (taVNS) has been proposed. The purpose of taVNS is to treat a disease non-invasively by applying electrical current to the cutaneous receptive field formed by the auricular branch of the vagus nerve in the outer ear.

Thirty C57BL/6 mice were divided into a control group (n=6), a model group (n=6), and three experimental groups (40, 20, 10 mg/kg of mollugin, n=6 each). DSS solution (3%) was given to mice in the model group and experimental groups from day 4 to day 10 to induce the mouse UC model.
