Molecular mechanisms regulating hormone-sensitive lipase and lipolysis.
HSL (hormone-sensitive lipase) is a key enzyme in the mobilization of fatty acids from acylglycerols in adipocytes as well as non-adipocytes. In adipocytes, catecholamines stimulate lipolysis mainly through PKA (protein kinase A)-mediated phosphorylation of HSL and perilipin, a protein coating the lipid droplet. The anti-lipolytic action of insulin is mediated mainly via lowered cAMP levels, accom
Incidence of Ischemic Stroke in Relation to Asymptomatic Carotid Artery Atherosclerosis in Subjects with Normal Blood Pressure. A Prospective Cohort Study.
Background:Approximately 10-20% of stroke cases have normal blood pressure (BP). The objective of this study was to explore whether the risk of ischemic stroke is related to the carotid intima-media thickness (CIMT) and atherosclerotic lesions in a cohort of subjects with normal BP. Methods:Common CIMT and the presence of carotid plaque were determined by B-mode ultrasound in 6,103 subjects, rando
Eosinophil infiltration and activation at the gastric ulcer margin in rats.
BACKGROUND : Recruitment and activation of eosinophils have been studied intensely in asthma and other allergic diseases. Less is known about the infiltration and behaviour of eosinophils during gastric ulcer healing. AIM : To examine the tissue infiltration and activation of eosinophils in the ulcer margin at different time points after ulcer induction (days 1-15). METHODS : Eosinophil peroxidase
Elevated Lp-PLA2 Levels Add Prognostic Information to The Metabolic Syndrome on Incidence of Cardiovascular Events Among Middle-Aged Nondiabetic Subjects.
Background-To explore potential interrelationships between lipoprotein-associated phosholipase A2 (Lp-PLA(2)), the metabolic syndrome (MetS), and incident cardiovascular disease (CVD). Methods and Results-MetS was defined by the National Cholesterol Education Program Adult treatment Panel III criteria in 4480 nondiabetic Malmo Diet and Cancer Study subjects without history of CVD. Incidence of fir
Differential Effects of Ferulic Acid and p-Coumaric Acid on S Phase Distribution and Length of S Phase in the Human Colonic Cell Line Caco-2
Ferulic acid (FA) and para-coumaric acid (p-CA) may mediate the protective effects of whole-grain cereals against colon cancer. Therefore, the effects of FA and p-CA on the metabolic activity, proliferation, cell cycle phase distribution, and kinetics of the colonic endothelial tumor cell line Caco-2 was studied. Both compounds at 1500 M decreased the number of cells to 43-75% of control after 2-3
Silent brain infarcts among stroke patients: innocent by-standers or prognostic determinants?
Ketogenic Diet Improves Sleep Quality in Children with Therapy-resistant Epilepsy.
Summary: Purpose: The study purpose was to evaluate sleep structure during ketogenic diet (KD) treatment in children with therapy-resistant epilepsy and to correlate possible alterations with changes in clinical effects on seizure reduction, seizure severity, quality of life (QOL), and behavior. Methods: Eighteen children were examined with ambulatory polysomnographic recordings initially and aft
Host cell responses to Chlamydia pneumoniae in gamma interferon-induced persistence overlap those of productive infection and are linked to genes involved in apoptosis, cell cycle, and metabolism
The respiratory pathogen Chlamydia (Chlamydophila) pneumoniae is associated with chronic diseases, including atherosclerosis and giant-cell arteritis, which are accompanied by the occurrence of these obligate intracellular bacteria in blood vessels. There, C. pneumoniae seems to be present in a persistent state. Persistence is characterized by modified bacterial metabolism and morphology, as well
Postponement and Speculation in Non-Commercial Supply Chains
Importance of the home environment for healthy aging: conceptual and methodological background of the European ENABLE-AGE Project.
Currently in Europe as well as in the United States, an increasing proportion of very old people remain living in their homes despite declines in physical and mental health. Together with the fact that the population of very old people is rapidly increasing (Mathers, Sadana, Salamon, Murray, Lopez, 2001; United Nations Development Programme, 2001), this poses new challenges to societal planning an
Highly repetitive work operations in a modern milking system. A case study of wrist positions and movements in a rotary system
With the use of electrogoniometers wrist positions and movements were measured in 13 milkers while working in a modern rotary milking system. The rotary system put considerable demands on the wrists and hands regarding both velocities and repetitiveness. Values were found close to those described in other repetitive industrial work with high risk of wrist and hand disorders. For the right hand the
Prolastin, a pharmaceutical preparation of purified human alpha 1-antitrypsin, blocks endotoxin-mediated cytokine release
Background: alpha 1-antitrypsin (AAT) serves primarily as an inhibitor of the elastin degrading proteases, neutrophil elastase and proteinase 3. There is ample clinical evidence that inherited severe AAT deficiency predisposes to chronic obstructive pulmonary disease. Augmentation therapy for AAT deficiency has been available for many years, but to date no sufficient data exist to demonstrate its
NEUROPEPTIDE Y DECREASES SYNAPTIC TRANSMISSION ONTO CCK-POSITIVE BASKET CELLS IN THE DENTATE GYRUS OF THE HIPPOCAMPUS
The Home Environment and Disability-Related Outcomes in Aging Individuals: What Is the Empirical Evidence?
Purpose: Building on the disablement process model and the concept of person-environment fit (p-e fit), this review article examines 2 critical questions concerning the role of home environments: (a) What is the recent evidence supporting a relationship between home environments and disability-related outcomes? and (b) What is the recent evidence regarding the effects of home modifications on disa
Common variants in the beta2-(Gln27Glu) and beta3-(Trp64Arg)--adrenoceptor genes are associated with elevated serum NEFA concentrations and type II diabetes
AIMS/HYPOTHESIS: Higher NEFA concentrations predict Type II (non-insulin-dependent) diabetes mellitus but it is not known whether higher NEFA concentrations are genetically determined or reflect coexisting obesity. To address this question we studied whether common variants in two genes encoding for key regulators of lipolysis, the beta2- and beta3- adrenoceptors (B2AR and B3AR) are associated wit
Radiative lifetimes and transition probabilities of astrophysical interest in ZrII
Radiative lifetimes of 16 odd levels belonging to the 4d(2)5p configuration of Zr II have been measured using a time-resolved laser-induced fluorescence technique with a single-step excitation process either from the ground state or from metastable levels belonging to the 4d(2)5s and 4d(3) configurations. For 12 levels, there were no previous results available. The new experimental results and the
Being given a cancer diagnosis in old age: A phenomenological study.
Objectives The aim of the study was to illuminate the lived experience of being given a cancer diagnosis in old age. Background Little research has been done on the experience of elderly people developing cancer and the impact of the illness on their lives. Such knowledge is needed to support elderly people in dealing with issues arising after cancer is diagnosed. Design A descriptive phenomeno
The palaeobiogeography of Silurian ramphoprionid Polychaete annelids
Silurian palaeobiogeography of the Ramphoprionidae (Annelida; Polychaeta) is outlined. Members of the family are reported from northern Europe (Estonia, Sweden and England), the Russian Arctic (Severnaya Zemlya), and the Canadian Arctic (Baillie-Hamilton Island), These areas were located fairly close to the palacoequator during the Silurian and a faunal exchange is indicated by the broad, intercon
Light-Driven Tyrosine Radical Formation in a Ruthenium-Tyrosine Complex Attached to Nanoparticle TiO2
We demonstrate a possibility of multistep electron transfer in a supramolecular complex adsorbed on the surface of nanocrystalline TiO2. The complex mimics the function of the tyrosineZ and chlorophyll unit P680 in natural photosystem II (PSII). A ruthenium(II) tris(bipyridyl) complex covalently linked to a L-tyrosine ethyl ester through an amide bond was attached to the surface of nanocrystalline
