Systematic pan-cancer analysis identifies transmembrane protein 158 as a potential therapeutic, prognostic and immunological biomarker.

The purpose of this study was to investigate the expression significance, predictive value, immunologic function, and biological role of transmembrane protein 158 (TMEM158) in the development of pan-cancer. To achieve this, we utilized data from multiple databases, including TCGA, GTEx, GEPIA, and TIMER, to collect gene transcriptome, patient prognosis, and tumor immune data. We evaluated the association of TMEM158 with patient prognosis, tumor mutational burden (TMB), and microsatellite instability (MSI) in pan-cancer samples.

Exploring the role and mechanism of gut microbiota in methamphetamine addiction using antibiotic treatment followed by fecal microbiota transplantation.

Recently, the role of the gut microbiota in the context of drug addiction has attracted the attention of researchers; however, the specific effects and underlying mechanisms require further exploration. To accomplish this, C57BL/6 mice were firstly treated with methamphetamine (MA). Conditioned place preference (CPP) behavior changes, gut permeability and function, microglial activation, and inflammatory cytokine expression were systematically analyzed in antibiotics-treated mice with microbiota depletion and in fecal microbiota transplantation mice with microbiota reconstitution.

IGF-1 Via PI3K/Akt/S6K Signaling Pathway Protects DRG Neurons with High Glucose-induced Toxicity.

Hyperglycemia-induced toxicity of neurons contributes to the pathogenesis and progression of diabetic neuropathy (DNP). High concentration glucose triggered reactive oxygen species (ROS) overproduction and induced cell apoptosis of neurons from dorsal root ganglion (DRG) in vitro. Currently, there is no effective therapeutic method to retard this devastating complication or neurotoxicity induced by high glucose.

The resistance effect of vegetation stem diameter on overland runoff under different slope gradients.

Vegetation is an important part of the natural environment and has resistance effects on overland runoff, which can effectively reduce hydraulic erosion. The effect of vegetation stem diameter and slope gradient on flow resistance is thus worthy of further study. The influence of three different slope gradients (s), three vegetation stem diameters (d) and 12 levels of unit discharge (q) on the flow resistance of a slope was simulated to systematically study the effect of vegetation stem diameter and slope gradient on overland runoff.

Chronic alcohol exposure induced gut microbiota dysbiosis and its correlations with neuropsychic behaviors and brain BDNF/Gabra1 changes in mice.

Alcohol addiction can cause brain dysfunction and many other diseases. Recently, increasing evidences have suggested that gut microbiota plays a vital role in regulating alcohol addiction. However, the exact mechanism has not yet been elucidated.

Resveratrol Suppresses Rotenone-induced Neurotoxicity Through Activation of SIRT1/Akt1 Signaling Pathway.

Rotenone is a common pesticide and has been reported as one of the risk factors for Parkinson disease. Rotenone can cause neuronal death or apoptosis through inducing oxidative injury and inhibiting mitochondrial function. As a natural polyphenolic compound, resveratrol possesses the antioxidant capacity and neuroprotective effect.

Roles of NAD in Protection of Axon against Degeneration via SIRT1 Pathways.

Axonal degeneration is a common pathological change of neurogenical disease which often arises before the neuron death. But it had not found any effective method to protect axon from degeneration. In this study we intended to confirm the protective effect of nicotinamide adenine dinucleotide (NAD), investigate the optimal administration dosage and time of NAD, and identify the relationship between silence signal regulating factor 1 (SIRT1) and axonal degeneration.

Resveratrol Protects PC12 Cell against 6-OHDA Damage via CXCR4 Signaling Pathway.

Resveratrol, herbal nonflavonoid polyphenolic compound naturally derived from grapes, has long been acknowledged to possess extensive biological and pharmacological properties including antioxidant and anti-inflammatory ones and may exert a neuroprotective effect on neuronal damage in neurodegenerative diseases. However, the underlying molecular mechanisms remain undefined. In the present study, we intended to investigate the neuroprotective effects of resveratrol against 6-OHDA-induced neurotoxicity of PC12 cells and further explore the possible mechanisms involved.

Melatonin treatment during the incubation of sensitization attenuates methamphetamine-induced locomotor sensitization and MeCP2 expression.

Behavior sensitization is a long-lasting enhancement of locomotor activity after exposure to psychostimulants. Incubation of sensitization is a phenomenon of remarkable augmentation of locomotor response after withdrawal and reflects certain aspects of compulsive drug craving. However, the mechanisms underlying these phenomena remain elusive.

Lithium protects against methamphetamine-induced neurotoxicity in PC12 cells via Akt/GSK3β/mTOR pathway.

Methamphetamine (MA) is neurotoxic, especially in dopaminergic neurons. Long-lasting exposure to MA causes psychosis and increases the risk of Parkinson's disease. Lithium (Li) is a known mood stabilizer and has neuroprotective effects.

Neuroprotection of resveratrol against neurotoxicity induced by methamphetamine in mouse mesencephalic dopaminergic neurons.

Resveratrol is originally extracted from huzhang, a Chinese herbal medicine. Recently, resveratrol has attracted a great of attention due to its antioxidant and antiapoptotic properties. Although the neuroprotection of resveratrol on neural damages in various models has been well characterized, little is known about the role of resveratrol in methamphetamine (MA) induced neurotoxicity in mesencephalic dopaminergic neurons.

Paliperidone Protects SH-SY5Y Cells Against MK-801-Induced Neuronal Damage Through Inhibition of Ca(2+) Influx and Regulation of SIRT1/miR-134 Signal Pathway.

Schizophrenia is a serious psychotic disease. Recently, increasing evidences support that neurodegeneration occurs in the brain of schizophrenia patients with progressive morphological changes. Paliperidone, an atypical antipsychotic drug, could attenuate psychotic symptom and protect neurons from different stressors.

Paliperidone protects SK-N-SH cells against glutamate toxicity via Akt1/GSK3β signaling pathway.

Schizophrenia is a heterogeneous psychotic illness and its etiology remains poorly understood. Recent studies have suggested that neurodegeneration is a component of schizophrenia pathology and some atypical antipsychotics appear to slow progressive morphological brain changes. In addition, the atypical antipsychotics were reported to have a superior therapeutic efficacy in treating schizophrenia and have a low incidence of extrapyramidal side effects (EPS) compared to typical antipsychotics.

Neuroprotective effects of resveratrol on damages of mouse cortical neurons induced by β-amyloid through activation of SIRT1/Akt1 pathway.

Resveratrol (3,5,4'-tihydroxy-trans-stilbene), a polyphenolic phytoalexin found in the skin and seeds of grapes, has been reported to possess a wide range of biological and pharmacological activities including antioxidant, anti-inflammatory, and antimutagenic effects. The present study intended to explore the neuroprotective effects of resveratrol against Aβ25-35 -induced neurotoxicity of cultured mouse cortical neurons and the possible mechanisms involved. For this purpose, mouse cortical neurons were cultured and exposed to 30 μM Aβ25-35 in the absence or presence of resveratrol (5, 10, and 25 μM).

[Artifical improvement of soil fertility in a regraded forest ecosystem by using municipal sewage sludge].

The increasing occurrence of forest ecosystem degradation is a serious problem in tropical and subtropical regions. Field experiments showed that the application of sludge from a sewage treatment plant could not only promote the growth and reproduction of trees, including the increase in the height and diameter of trees and thus being advantageous to the growth of shrub and herb of trees, but also improve soil fertility such as increasing soil organic matter and available nitrogen and phosphorus. The test of residual heavy metals of soil indicated that the application of sludge increased the content of Pb in the soil and the increment of Pb was varied with the increase of sludge usage.
