Efficacy of single and repeated administration of ketamine in unipolar and bipolar depression: a meta-analysis of randomized clinical trials

open access: yesPharmacological Reports, 2020
Due to unmet clinical needs for efficient drugs with a rapid onset of antidepressant effects, we aimed to evaluate the efficacy of single-dose ketamine in different subgroups of patients with major depression and establish whether repeated ketamine ...

Spatially Programmable Electroadhesive Enables In Situ Site‐Selective Functional Coupling

open access: yesAdvanced Materials, EarlyView.
A light‐activated, in situ spatially programmable bioadhesive (STICH) enables microscale, site‐selective integration of bioelectronic devices with wet tissue. It achieves robust mechanical bonding and low‐impedance electrical coupling, enabling reconfigurable neuromodulation and directional electromechanical sensing in vivo and ex vivo.

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

open access: yesAdvanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

Ketamine induces apoptosis in lung adenocarcinoma cells by regulating the expression of CD69

open access: yesCancer Medicine, 2018
Ketamine, an anesthetic, analgesic, or sedative, is widely used for the treatment of cancer pain. Recently, ketamine has been also reported to be tumor repressor for inhibiting proliferation, invasion, and migration, and inducing apoptosis in many ...

Exploring Functionally Enhanced BLP‐Trained Macrophage Subpopulations in S. Aureus Infection: Underlying Mechanisms and Therapeutic Significance

open access: yesAdvanced Science, EarlyView.
BLP‐trained macrophages show augmented resistance to infection, but their mechanisms remain unclear. scRNA‐seq identified 13 BMDM subsets, with two novel anti‐inflammatory/antibacterial subpopulations (C5/C7) emerging post‐BLP training. BLP training activates NRF2, attenuates oxidative stress/ferroptosis, and boosts glycolysis/OXPHOS. Adoptive transfer

Regular versus Irregular Exercise Differentially Modulates Hippocampal‐Hepatic Acetylcholine Flux to Coordinate Fear Memory Extinction and Liver Inflammation

open access: yesAdvanced Science, EarlyView.
Ma et al. report the hippocampal and hepatic acetylcholine (ACh) levels are differently modulated by regular versus irregular exercise, which contributes to coordinate hippocampal astrocyte activity and hepatic FBXL6high neutrophil recruitment. This ACh‐modulated brain‐liver circuit links the effects of exercise on fear memory extinction and liver ...

Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

open access: yesAdvanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time

A Comparison of xylazine/ketamine, diazepam/ketamine and acepromazine/ketamine anaesthesia in Rabbit

open access: yesSokoto Journal of Veterinary Sciences, 2015
The efficacy and safety of the recommended intramuscular (im) clinical doses of xylazine-ketamine (5mg-35mg/kg), diazepam-ketamine (5mg-60mg/kg) and acepromazine-ketamine (5mg-75mg/kg) post administration were obtained, evaluated and compared using the following parameters in 10 apparently healthy rabbits: vital parameters (means of heart rates ...

Potentiating Cerebral Perfusion Normalizes Glymphatic Dynamics in Systemic Inflammation

open access: yesAdvanced Science, EarlyView.
LPS‐induced systemic inflammation increases glymphatic influx but delays cervical lymphatic drainage, accompanied by AQP4 depolarization and impaired glymphatic clearance. Enhancing cerebral blood flow via the inotropic agent levosimendan effectively restored AQP4 polarization, improving glymphatic flux and amyloid‐β clearance.

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis

open access: yesHepatology, EarlyView., 2022
Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.
