alleviates CUS-induced depression-like behaviors in mice the gut microbiota-neuroinflammation axis.

Major depressive disorder is a mental disease with complex pathogenesis and treatment mechanisms involving changes in both the gut microbiota and neuroinflammation. Cuscutae Semen (CS), also known as Chinese Dodder seed, is a medicinal herb that exerts several pharmacological effects. These include neuroprotection, anti-neuroinflammation, the repair of synaptic damage, and the alleviation of oxidative stress.

Sirtuin Type 1 Mediates the Antidepressant Effect of S-Ketamine in a Chronic Unpredictable Stress Model.

Background: Major depressive disorder (MDD) refers to a mental disease with complex pathogenesis and treatment mechanism. S-ketamine exhibited high effectiveness in treating MDD. However, the pharmacological activity of S-ketamine has not been reported yet.

Morphological and hemispheric and sex differences of the anterior ascending ramus and the horizontal ascending ramus of the lateral sulcus.

Broca's area is composed of the pars opercularis (PO) and the pars triangularis (PTR) of the inferior frontal gyrus; the anterior ascending ramus of the lateral sulcus (aals) separates the PO from the PTR, and the horizontal ascending ramus of the lateral sulcus (hals) separates the PTR from the pars orbitalis. The morphometry of these two sulci maybe has potential effects on the various functions of Broca's area. Exploring the morphological variations, hemispheric differences and sex differences of these two sulci contributed to a better localization of Broca's area.

Synaptic Ultrastructure Might Be Involved in HCN-Related BDNF mRNA in Withdrawal-Anxiety After Ethanol Dependence.

Withdrawal from ethanol dependence has been associated with heightened anxiety and reduced expression of Brain-derived neurotropic factor which promotes the synaptic transmission and plasticity of synapses. Hyperpolarization-activated cyclic nucleotide-gated channel 1 regulates expression; however, whether Hyperpolarization-activated cyclic nucleotide-gated channel 1-related Brain-derived neurotropic factor is involved in the synaptic ultrastructure that generates withdrawal-anxiety has been poorly perceived. Sprague-Dawley rats were treated with ethanol 3-9% (v/v) for a period of 21 days.

Applying ketamine to alleviate the PTSD-like effects by regulating the HCN1-related BDNF.

Background: Post-traumatic stress disorder (PTSD) is commonly associated with concurrent anxiety and depression symptoms, and reduce the expression of the Brain-Derived Neurotrophic Factor (BDNF) which promotes the proliferation and survival of neurons. The hyperpolarization-activated cyclic nucleotide-gated channel 1(HCN1) could be inhibited by the ketamine, a drug to alleviate depression and anxiety, and regulated the BDNF expression, however, the effects of ketamine in alleviating PTSD symptoms by regulating the HCN1-related BDNF have been poorly perceived.

Methods: In the present study, the effects of ketamine were examined on the PTSD-like effects in a rat model of PTSD induced by SPS&S procedure.
