Selective Orexin 2 Receptor Blockade Alleviates Cognitive Impairments and the Pathological Progression of Alzheimer's Disease in 3xTg-AD Mice.

The orexin system is closely related to the pathogenesis of Alzheimer's disease (AD). Orexin-A aggravates cognitive dysfunction and increases amyloid β (Aβ) deposition in AD model mice, but studies of different dual orexin receptor (OXR) antagonists in AD have shown inconsistent results. Our previous study revealed that OX1R blockade aggravates cognitive deficits and pathological progression in 3xTg-AD mice, but the effects of OX2R and its potential mechanism in AD have not been reported.

Trichostatin A relieves anxiety-and depression-like symptoms in APP/PS1 mice.

Background: Cognitive deficits and behavioral disorders such as anxiety and depression are common manifestations of Alzheimer's disease (AD). Our previous work demonstrated that Trichostatin A (TSA) could alleviate neuroinflammatory plaques and improve cognitive disorders. AD, anxiety, and depression are all associated with microglial inflammation.

Spontaneous cerebrospinal fluid rhinorrhea: A case report and analysis.

Introduction: Spontaneous cerebrospinal fluid leakage is usually caused by developmental abnormalities and is rare, accounting for approximately 5% of the cases of cerebrospinal fluid (CSF) leakage. To the best of our knowledge, clival dysplasia-caused CSF rhinorrhea has never been reported in the neurosurgical field.

Conclusion: Spontaneous cerebrospinal fluid rhinorrhea is often treated by surgery, and a transsphenoidal approach repair is the main surgical method used, offering the advantages of less trauma, fewer complications, rapid postoperative recovery, and low recurrence rate.

Anti-hepatocarcinoma activity of TT-1, an analog of melittin, combined with interferon-α via promoting the interaction of NKG2D and MICA.

Hepatocarcinoma is one of the malignant cancers with significant morbidity and mortality. Immunotherapy has emerged in clinical treatment, owing to the limitation and severe side effects of chemotherapy. In the immune system, natural killer (NK) cells are important effectors required to eliminate malignant tumor cells without the limitation of major histocompatibility complex (MHC) molecule issues.

Combination doxorubicin and interferon-α therapy stimulates immunogenicity of murine pancreatic cancer Panc02 cells via up-regulation of NKG2D ligands and MHC class I.

Background: Pancreatic adenocarcinoma is a malignant gastrointestinal cancer with significant morbidity and mortality. Despite severe side effects of chemotherapy, the use of immunotherapy combined with chemotherapy has emerged as a common clinical treatment. In this study, we investigated the efficacy of the combined doxorubicin and interferon-α (IFN-α) therapy on murine pancreatic cancer Panc02 cells in vitro and in vivo and underlying mechanisms.

Inhibition of cytochrome P450 enzymes by rhein in rat liver microsomes.

Rhein, an active ingredient extensively found in plants such as Aloe, Cassitora L., rhubarb and so on, has been used for a long time in China. Pharmacological tests revealed that rhein not only had a strong antibacterial action, but also may be useful in cancer chemotherapy as a biochemical modulator.

Effect of the water extract and ethanol extract from traditional Chinese medicines Angelica sinensis (Oliv.) Diels, Ligusticum chuanxiong Hort. and Rheum palmatum L. on rat liver cytochrome P450 activity.

Angelica sinensis (Oliv.) Diels (DG), Ligusticum chuanxiong Hort. (CX) and Rheum palmatum L.

Metabolism and effect of para-toluene-sulfonamide on rat liver microsomal cytochrome P450 from in vivo and in vitro studies.

Aim: To study the in vivo and in vitro metabolism and the effect of para-toluene-sulfonamide (PTS) on cytochrome P450 enzymes (CYP450).

Methods: Total CYP450 and microsome protein content were determined after iv pretreatment of rats with PTS. CYP-specific substrates were incubated with rat liver microsomes.

[Simultaneous determination of three probe drugs by reversed-phase high performance liquid chromatography].

A reversed-phase high performance liquid chromatographic method was developed for the simultaneous quantitative determination of caffeine, dapsone and chlorzoxazone. The operation was carried out on a C18 column (250 mm x 4.6 mm i.
