Dioscin integrates regulation of monosaturated fatty acid metabolism to extend the life span through XBP-1/SBP-1 dependent manner.

Delay aging, especially in healthy life extension, brought the most interest to the medical field. Searching for anti-aging drugs with relative safety profiles bring natural products in hotspot. In this study, we find that dioscin promotes the health span extension in wild-type .

Sanguinarine promotes healthspan and innate immunity through a conserved mechanism of ROS-mediated PMK-1/SKN-1 activation.

The longevity of an organism is influenced by both genetic and environmental factors. With respect to genetic factors, a significant effort is being made to identify pharmacological agents that extend lifespan by targeting pathways with a defined role in the aging process. Sanguinarine (San) is a benzophenanthridine alkaloid that exerts a broad spectrum of properties.

Secondary Metabolites from Marine Micromonospora: Chemistry and Bioactivities.

Marine Micromonospora was revealed to be a rather untapped and a rich source of chemically diverse and unique bioactive natural products. This review is aimed to make a comprehensive survey of secondary metabolites that were derived from marine Micromonospora including chemical diversity and biological activities. A total of 116 compounds from 41 marine Micromonospora species have been reported, covering the literatures from 1997 to 2019.

Methods: The surgical procedure of simultaneous correction includes RESULTS:: Satisfactory outcomes were achieved in all 22 patients.

Testosterone-cortisol dissociation in children exposed to prenatal maternal stress, and relationship with aggression: Project Ice Storm.

Prenatal maternal stress (PNMS) has been associated with postnatal behavioral alterations that may be partly explained by interactions between the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes. Yet it remains unclear whether PNMS leads to enduring HPA-HPG alterations in the offspring, and whether HPA-HPG interactions can impact behavior during development, in particular levels of aggression in childhood. Here we investigated the relationship between a marker for HPG axis function (baseline testosterone) and a marker for HPA axis response (cortisol area under the curve) in 11½-year-olds whose mothers were exposed to the 1998 Quebec ice storm during pregnancy (n = 59 children; 31 boys, 28 girls).

New Application of Psoralen and Angelicin on Periodontitis With Anti-bacterial, Anti-inflammatory, and Osteogenesis Effects.

Psoralen and angelicin are two effective compounds isolated from psoraleae, a traditional Chinese medicine. They have a wide range of applications for bone disease treatment and immune modulation. In this study, we explored their new applications for the treatment of periodontal diseases.

Porphyromonas gingivalis lipopolysaccharide induces cognitive dysfunction, mediated by neuronal inflammation via activation of the TLR4 signaling pathway in C57BL/6 mice.

Background: Porphyromonas gingivalis lipopolysaccharide (P. gingivalis-LPS) is one of the major pathogenic factors of chronic periodontitis (CP). Few reports on the correlation between P.

[Knockdown of DNA-PKcs inhibits cell cycle and its mechanism of drug-resistant Bel7402/5-Fu hepatocellular carcinoma cells].

Objective To study the effect of the knock-down of the DNA-dependent protein kinase catalytic subunit (DNA-PKcs) on the cell cycle of the multidrug-resistant (MDR) Bel7402/5-Fu hepatocellular carcinoma cells and its MDR mechanism. Methods After cationic liposome-mediated siDNA-PKcs oligonucleotide transfection, the drug sensitivity of Bel7402/5-Fu cells to 5-fluorouracil (5-Fu) and adriamycin (ADM) was determined by MTT assay; the cell cycle were detected by flow cytometry; meanwhile, the protein expressions of cell cycle-related proteins P21, cell cycle protein B1 (cyclin B1), cell cycle division protein 2 (CDC2) were tested by Western blotting; the expressions of ataxia telangiectasia mutated (ATM) and p53 at both mRNA and protein levels were detected by real-time PCR and Western blot analysis. Results The MTT results showed siDNA-PKcs increased the chemotherapeutic sensitivity of Bel7402/5-Fu cells to 5-Fu and ADM.

Hesperidin induces apoptosis and G0/G1 arrest in human non-small cell lung cancer A549 cells.

Lung cancer has high incidence and mortality rates worldwide. In the present study, the mechanisms by which hesperidin decreases the viability and induces the apoptosis of human non-small cell lung cancer (NSCLC) A549 cells were investigated. Initially, MTT and flow cytometric assays were performed to evaluate the effects of hesperidin on the viability and apoptosis of A549 cells and human normal lung epithelial BEAS-2B cells.

Peritraumatic Distress Mediates the Effect of Severity of Disaster Exposure on Perinatal Depression: The Iowa Flood Study.

Disaster exposure during pregnancy has received limited attention. This study examined the impact of the 2008 Iowa Floods on perinatal maternal depression and well-being, and the role of peritraumatic distress as a possible mechanism explaining this link. Perinatal women (N = 171) completed measures of depressive symptoms and general well-being at 5 timepoints from pregnancy to 30 months postpartum.

Partner support and maternal depression in the context of the Iowa floods.

A systematic investigation of the role of prenatal partner support in perinatal maternal depression was conducted. Separate facets of partner support were examined (i.e.

Brief communication: prenatal and early postnatal stress exposure influences long bone length in adult rat offspring.

Stress during the prenatal and early postnatal periods (perinatal stress, PS) is known to impact offspring cognitive, behavioral, and physical development, but effects on skeletal growth are not clear. Our objective was to analyze effects of variable, mild, daily PS exposure on adult offspring long bone length. Twelve pregnant rat dams were randomly assigned to receive variable stress from gestational days 14-21 (Prenatal group), postpartum days 2-9 (Postnatal), both periods (Pre-Post), or no stress (Control).
