    ECa 233 is the standardized extract of

    (L.) Urban. (Apiaceae). It contains at least 85% of triterpenoid glycosides and yields neuroprotective and memory-enhancing effects. However, the exact molecules exerting the effects might be triterpenic acid metabolites reproduced through gut metabolism after orally ingesting

    , not triterpenoid glycosides.

    This study demonstrates the effect of unmetabolized ECa 233 on hippocampal synaptic plasticity after directly perfusing ECa 233 over acute brain slices.

    The brain slices obtained from 7-week-old male Wistar rats were randomly divided into 4 groups. We perfused either artificial cerebrospinal fluid (ACSF), 0.01% DMSO, 10 µg/mL ECa 233, or 100 µg/mL on brain slices, and measured the long-term potentiation (LTP) magnitude to determine the synaptic plasticity of hippocampal circuits in each group.

    The LTP magnitude of ACSF, DMSO, 10 ug/mL ECa 233, and 100 ug/mL ECa 233 groups increased from 100% to 181.26 ± 38.19%, 148.74 ± 5.40%, 273.71 ± 56.66%, 182.17 ± 18.61%, respectively. ECa 233 at the concentration of 10 µg/mL robustly and significantly enhanced hippocampal LTP magnitude. The data indicates an improvement of the hippocampal synaptic plasticity.

    This study emphasizes the effectiveness of triterpenoid glycosides in ECa 233 on synaptic plasticity enhancement. Therefore, this study supported and complimented the known effects of

    extract on the enhancement of synaptic plasticity, and subsequently, learning and memory, suggesting that ECa 233 could be a promising memory enhancing agent.

FTD is associated with complex changes in neural networks of gustatory processing which may be responsible for eating abnormalities. Here, we present a 66-years-old lady suffered from behavioral variant of FTD with an interesting symptom of food aversion, typically sour foods.Objectives Chronic kidney disease (CKD) is a common cause of restless leg syndrome (RLS). RLS is under-recognized, misdiagnosed and undertreated disorder in our locality. In this study, we aimed to determine the prevalence of RLS due to CKD and its predictors.Methods This cross-sectional study included 520 patients [male =200; female =320; age 48.45 ± 3.63yrs; uremia duration 6.44 ± 1.65yrs; CKD5D = 400; CKD3D = 120). RLS diagnosis was done by clinical interviewing according to International RLS Study Group criteria. All underwent detailed biochemical testing and iron and ferritin levels’ measurements. Insomnia, depression and anxiety severities were assessed using insomnia sleep index (ISI), Beck Depression Inventory (BDI-II) and State-Trait Anxiety Inventory for Adults (STAI-AD) scales.Results RLS was found in 22.31% [ESKD =26%, CKD3D = 10%]. Insomnia, depression and anxiety were found in 76.15%, 91.15% and 44.23%. Insomnia was correlated with depression (r = 0.488, p = 0.001) and anxiety (r = 0.360, p = 0.006) but not RLS. Multiple linear regression analysis showed that ESKD (OR =3.8, 95%CI =2.5-8.5, p = 0.001), inadequate dialysis (OR =4.6, 95%CI =3.5-8.6, p = 0.001), hyperparathyroidism (OR =5.1, 95%CI 3.2-13.7, p = 0.0001) and peripheral neuropathy (OR =5.6, 95%CI =3.8-12.8, p = 0.0001) were independently associated with RLS.Conclusion The prevalence of RLS with CKD is 22.31%. It is 2.6 times more frequent and severe with ESKD compared to CKD3D. selleck inhibitor It seems that RLS may occur early with CKD and becomes worse with progressive kidney impairment. Also, insomnia, depression and anxiety are common with CKD. Insomnia, depression and anxiety were common with CKD but their severities were not correlated with RLS. Predictors for RLS were ESKD, inadequacy of dialysis, hyperparathyroidism and peripheral neuropathy.Airway basal cells are crucial for regeneration of the human lung airway epithelium, and are thought to be important contributors to Chronic Obstructive Pulmonary Disease (COPD) and other lung disorders. In order to reveal how basal cells contribute to disease, and to discover novel therapeutic targets, these basal cells need to be further characterized. In this study, we optimized a flow cytometry-based cell sorting protocol for primary human airway basal cells dependent on cell size and Nerve-Growth Factor Receptor (NGFR) expression. The basal cell population was found to be molecularly and functionally heterogeneous in contrast to cultured basal cells. In addition, significant differences were found such as KRT14 expression exclusively existing in cultured cells. Also, colony-forming capacity was significantly increased in cultured cells showing a clonal enrichment in vitro. Next, by single cell RNA sequencing on primary basal cells from healthy donors and GOLD stage IV COPD patients, the gene expression revealed a continuum ranging from healthy basal cell signatures to diseased basal cell phenotypes. We identified several upregulated genes that may indicate COPD, such as stress response related genes GADD45B and AHSA1, along with genes involved in the response to hypoxia such as CITED2 and SOD1. Taken together, the presence of healthy basal cells in stage IV COPD demonstrates the potential for regeneration through the discovery of novel therapeutic targets. In addition, we show the importance of studying primary basal cells when investigating disease mechanisms as well as for developing future cell-based therapies in the human lung.In a new born pig cystic fibrosis (CF) model, the ability of gland-containing airways to fight infection was affected by at least two major host-defense defects impaired mucociliary transport and a lower airway-surface liquid (ASL) pH. In the gland-containing airways, ASL pH is balanced by CFTR and ATP12A, which respectively control HCO3- transport and proton secretion. We found that, although porcine small airway tissue expressed little ATP12A, the ASL of epithelial cultures from CF distal small airways (diameter less then 200 μm) were nevertheless more acidic (compared to non-CF). Therefore, we hypothesized that gland-containing airways vs. small airways control acidification using distinct mechanisms. Our microarray data suggested that small airway epithelia mediate proton secretion via ATP6V0D2, an isoform of the V0d subunit of the H+-translocating plasma membrane V-type ATPase. Immunofluorescence of small airways verified the expression of the V0d2 subunit isoform at the apical surface of Muc5B+ secretory cells, but not ciliated cells.
