Nicotinamide N-methyltransferase (NNMT), which converts nicotinamide (NA) to 1-methylnicotinamide (MNA), is up-regulated in the cirrhotic liver. Because MNA displays PGI(2)-dependent anti-inflammatory effects, the up-regulation of NNMT may play a regulatory role in liver inflammation. In the present work, we analyzed changes in NNMT activity in the liver and concomitant changes in the concentra...

Nabumetone, a widely used nonsteroidal anti-inflammatory drug, requires biotransformation into 6-methoxy-2-naphthylacetic acid (6-MNA), a close structural analog to naproxen, to achieve its analgesic and anti-inflammatory effects. Despite its wide use, the enzymes involved in metabolism have not been identified. In the present study, several in vitro approaches were used to identify the cytochr...

BACKGROUND/AIMS Aged people are an increasing population group worldwide, and nutritional impairments may contribute to additional health problems. The characterization of food consumption of elderly people is a good approach to implementing adequate nutritional policies in order to improve their nutritional status. The aim of this study was to describe and analyze specific aspects of food inta...

The aim of this study was to evaluate whether morphometrical analysis can be of diagnostic value for canine acanthomatous ameloblastoma. We calculated, by means of an automated image analyser, some morphometric nuclear parameters, in particular: mean nuclear area (MNA), mean nuclear perimeter (MNP), maximum and minimum diameters (MDx and MDm) coefficient of variation of the nuclear area (NACV),...

BACKGROUND Methylnicotinamide (MNA) displays vasoprotective activity, however, the regulation of the activity of nicotinamide-N-methyltransferase (NNMT), is largely unknown. We analyze a possible involvement of IL-6 in the activation of NNMT-MNA pathway during an endurance exercise. METHODS FVB, C57Bl/6J IL6(+/+) and C57Bl/6J IL-6(-/-) mice were subjected to the single bout of endurance exerc...

For many years, 1-methylnicotinamide (MNA), a primary metabolite of nicotinamide, has been considered inactive. Recently however, it has been discovered that MNA possesses anti-thrombotic and anti-inflammatory activity. In the present study we investigated whether chronic administration of MNA to hypertriglyceridemic or diabetic rats would reverse endothelial dysfunction characterized by the im...

Continuación de la revisión historia del Museo Nacional Antropología Ciudad México (MNA) y su sala colección teotihuacanas a partir creación nuevo edificio para este museo en el Bosque Chapultepec 1964. Explicamos gran esfuerzo que significó planeación, construcción montaje MNA teotihuacana particular;
 así como las novedades aquel proyecto museístico. Se investigaron procedencias e piezas...

Nutrition is a key element in geriatric health and is important for functional ability. The present study examined the functional status-predictive ability of the Mini-Nutritional Assessment (MNA). We analysed the dataset of the 'Survey of Health and Living Status of the Elderly in Taiwan', a population-based study conducted by the Bureau of Health Promotion of Taiwan. Study subjects (≥65 years...

We previously reported that 3 p53 wild type (wt) MYCN amplified (MNA) neuroblastoma cell lines failed to G1 arrest after DNA damage despite induction of p53, p21(WAF1) and MDM2. We hypothesised that this was due to high MYCN expression. p53 responses to DNA damage were examined in an additional 13 p53 wt neuroblastoma cell lines. MNA was significantly associated with a failure to G1 arrest afte...
