Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

[H-3]dihydroalprenolol binding to beta adrenergic receptors in multiple sclerosis brain

, 2000
By using immunocytochemistry we previously reported the absence of beta(2) adrenergic receptors on astrocytes in multiple sclerosis (MS) white matter. Here, we measured beta(1) and beta(2) adrenergic receptor concentrations in postmortem brain sections ...

The Effect of a Reduced-Calorie Diet on alpha-2 Adrenergic Receptor Responsiveness in Abdominal Adipose Tissue in Obese Men During Exercise [PDF]

, 2008
There is at present an imperfect understanding of the effect of diet on availability of inhibitory receptors in fat cells during exercise among obese men. *Objective:* The purpose of this study was to determine whether diet results in

The interaction of verapamil and norverapamil with beta-adrenergic receptors.

, 1985
To determine the effect of calcium-channel blockers on beta-adrenergic receptors, we studied the interactions of verapamil, diltiazem, and nifedipine with both human lymphocyte beta 2-adrenergic receptors and rat myocardial beta 1-adrenergic receptors by

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

scGEN: Leveraging an Adaptive Weighting Strategy for Challenging Cell Clustering in Single‐Cell RNA‐seq

Advanced Science, EarlyView.
scGEN combines attribute–structure encoding, adaptive hard‐sample weighting, and regularized zero‐inflated negative binomial loss to resolve ambiguous single‐cell states. In the developing human pituitary, refined annotations reveal Pre.Gonado cells at 7 weeks and previously obscured developmental communication networks.

Molecular Landscapes of Tumor Dormancy in Gynecologic Malignancies: From Survival Mechanisms to Precision Interception

Advanced Science, EarlyView.
This Review outlines the biological framework of entry, maintenance, and awakening in dormant minimal residual disease across gynecologic cancers. By mapping critical biological dependencies—from metabolic plasticity to microenvironment interactions—it evaluates novel interception concepts and presents a translational framework combining single‐cell ...

Imipramine Increases Norepinephrine and Serotonin in the Salivary Glands of Rats

Biology
Xerostomia induced by antidepressants such as imipramine has long been thought to be due to their anticholinergic effects. However, even antidepressants with low anticholinergic effects may have a high incidence of xerostomia.

Relaxation of Isolated Human Myometrial Muscle by beta2-Adrenergic Receptors but Not beta1-Adrenergic Receptors

, 1998
OBJECTIVE: Human myometrium contains both beta1-adrenergic and beta2-adrenergic receptors. This study was designed to assess the importance of each beta-adrenergic receptor subtype in relaxation of human myometrial muscle strips.

Modulation of Presynaptic Inhibitory Retinal Circuits for Retinal Ganglion Cell Neuroprotection in Glaucoma

Advanced Science, EarlyView.
Ocular hypertension induces early hyperactivity in inner retinal inhibitory circuitry before substantial retinal ganglion cell loss. Sustained pharmacological inhibition of GABAergic/glycinergic neurotransmission and Vgat‐targeted Lin28 expression suppress this hyperactivity and improve RGC survival without reducing intraocular pressure. These findings
