Objective: To investigate the correlation between age-related hearing loss and cognitive impairment. Methods: 201 elderly patients, who were admitted to the Department of Otorhinolaryngology of Peking University People's Hospital from March 1, 2017 to March 31, 2017, were evaluated with hearing screening and the Montreal Cognitive Assessment Scale. Among them, 101 were female and 100 were male, aged 60-90 years old. Taking the cognitive level as the dependent variable, and taking the age, sex, education, occupation, marital status, residence, and average hearing loss (average hearing threshold of 500, 1 000, 2 000, and 4 000 Hz), as well as the length of conscious hearing loss as the independent variables, the single factor analysis and multivariate linear regression analysis were used to screen the main factors affecting the cognitive level of the elderly...

The Perlin effect and its analog for fluorinated compounds (the fluorine Perlin-like effect) manifest on one-bond C-H (C-F for the fluorine Perlin-like effect) spin-spin coupling constants (SSCC´s) in six-membered rings. These effects can be useful to probe the stereochemistry (axial or equatorial) of the C-H and C-F bonds, respectively. The origin of these effects has been debatable in the literature as being due to hyperconjugative interactions, dipolar effects and induced current density. Accordingly, a variety of model compounds has been used to probe such effects, since the cyclohexanone carbonyl group and the endocyclic heteroatom lone pairs play different roles on the above-mentioned effects...

OBJECTIVE: Spastic dystonia is one of the positive phenomena of the upper motor neuron syndrome (UMNS). It is characterised by the inability to relax a muscle leading to a spontaneous, although stretch-sensitive, tonic contraction. Although spastic dystonia is a recognized cause of muscle hypertonia, its prevalence among hypertonic muscles of stroke subjects has never been investigated. Differently from spasticity, which is an exaggerated stretch reflex, spastic dystonia is viewed as an efferent phenomenon, due to an abnormal central drive to motoneurons...

Metastatic dissemination of tumor cells represents a major obstacle towards cancer cure. Tumor cells with metastatic capacity are often resistant to chemotherapy. Experimental efforts revealed that the metastatic cascade is a complex process that involves multiple positive and negative regulators. In this respect, several metastasis suppressor genes have been described. Here, we review the role of the metastasis suppressor KiSS1 in regulation of metastasis and in response to antitumor agents. Physiologically, KiSS1 plays a key role in the activation of the hypothalamic-pituitary-gonadal axis regulating puberty and reproductive functions...

27-Hydroxycholesterol (27OHChol) is a bioactive molecule that induces monocytic cell activation and differentiation and thereby participates in immune responses under hypercholesterolemic condition. However, it is unknown whether cyclosporin A (CsA), an immunosuppressant, affects biological effects of 27OHChol. In this study, we investigated whether CsA alters 27OHChol-induced cellular and molecular responses using the human monocyte/macrophage THP-1 cells. Treatment of the cells with CsA resulted in decreased expression of the mDC-specific markers (CD80, CD83 and CD88) induced by 27OHChol...

This work evaluated the effects of long-term kefir treatment in cardiac function (cardiac contractility and calcium-handling proteins) and the central nervous system (CNS) control of the sympathetic signaling in spontaneously hypertensive rats (SHR). Male normotensive rats [Wistar Kyoto rats (WKYs)] and SHRs were divided into three groups: WKYs and SHRs treated with vehicle, and SHRs treated with milk fermented by the grains of kefir (5%; SHR-Kefir; oral gavage, 0.3 ml/100 g daily/9 weeks). At the end of treatment, mean arterial pressure (MAP) and heart rate (HR) were measured by direct arterial catheterization...

Maternal nutritional imbalances trigger developmental adaptations involving early epigenetic mechanisms associated with adult chronic disease. Maternal high-fat (HF) diet promotes obesity and hypothalamic leptin resistance in male rat offspring at weaning and adulthood. Leptin resistance is associated with over activation of the endocannabinoid system (ECS). The ECS mainly consists of endocannabinoids derived from n-6 fatty acids and cannabinoid receptors (CB1 coded by Cnr1 and CB2 coded by Cnr2). The CB1 activation in hypothalamus stimulates feeding and appetite for fat while CB2 activation seems to play an immunomodulatory role...

The development of atomic magnetometers has led to nuclear magnetic resonance (NMR) in zero and ultralow magnetic fields without using cryogenic sensors. However, in-situ detection, meaning that a sample locates in the detection space beside a vapor cell, has been conducted only with parahydrogen-induced polarization. Other hyperpolarization techniques remain unexplored yet. In this work, we demonstrate that Overhauser dynamic nuclear polarization allows in-situ NMR detection with an atomic magnetometer at less than 1 μT...

Adverse life experiences (ALEs) are associated with hyperalgesia and chronic pain, but the underlying mechanisms are poorly understood. One potential mechanism is hyperexcitability of spinal neurons (i.e., central sensitization). Given that Native Americans (NA) are more likely to have ALEs, and have a higher prevalence of chronic pain, the relationship between ALEs and spinal hyperexcitability might contribute to their pain risk. The present study assessed temporal summation of the nociceptive flexion reflex (TS-NFR; correlate of spinal hyperexcitability) and pain (TS-Pain) in 246 healthy, pain-free non-Hispanic whites (NHW) and Native Americans (NA)...

P2X4 receptor (P2X4R), a subtype of P2 purinergic receptors, is an ATP-gated receptor through which activity of spinal microglia instigates pain hypersensitivity in various pain conditions. Accumulating evidence indicates that monocyte chemoattractant protein-1 (MCP-1) plays an important role in chronic pain facilitation, and it could stimulate microglia activation and involve in regulating P2X4R expression. However, the mechanism of MCP-1 in regulating the expression of P2X4R in microglia is poorly understood, and whether MCP-1 can aggravate pain via up-regulating spinal P2X4R expression in Cancer-induced Bone Pain (CIBP) remains unclear...

Early Embryonic Arrest (EEA) is one of the major causes of female infertility. Genetic factors including specific genes and miRNAs may play pivotal roles on EEA. However, it is not well defined what genes and micro RNAs participate the pathophysiological alterations of EEA. In this work, we compared the Transcriptome -Seq and microRNA profiles from three pairs of villi (three EEA patients and three normal pregnancy, NP). We first confirmed the array data by qPCR with ten randomly selected differentially expressed genes and ten differentially expressed miRNAs in villi from 20 EEA and 20 NP controls...
