Ciliary Neurotrophic Factor Stimulates Muscle Glucose Uptake by a PI3-Kinase–Dependent Pathway That Is Impaired With Obesity
Authors: Steinberg Gregory R. , Watt Matthew J. , Ernst Matthias , Birnbaum Morris J. , Kemp Bruce E. , Jørgensen Sebastian Beck
Published: January 2009

OBJECTIVE

Ciliary neurotrophic factor (CNTF) reverses muscle insulin resistance by increasing fatty acid oxidation through gp130-LIF receptor signaling to the AMP-activated protein kinase (AMPK). CNTF also increases Akt signaling in neurons and adipocytes. Because both Akt and AMPK regulate glucose uptake, we investigated muscle glucose uptake in response to CNTF signaling in lean and obese mice.

RESEARCH DESIGN AND METHODS

Mice were injected intraperitoneally with saline or CNTF, and blood glucose was monitored. The effects of CNTF on skeletal muscle glucose uptake and AMPK/Akt signaling were investigated in incubated soleus and extensor digitorum longus (EDL) muscles from muscle-specific AMPKα2 kinase-dead, gp130ΔSTAT, and lean and obese ob/ob and high-fat–fed mice. The effect of C2-ceramide on glucose uptake and gp130 signaling was also examined.

RESULTS

CNTF reduced blood glucose and increased glucose uptake in isolated muscles in a time- and dose-dependent manner with maximal effects after 30 min with 100 ng/ml. CNTF increased Akt-S473 phosphorylation in soleus and EDL; however, AMPK-T172 phosphorylation was only increased in soleus. Incubation of muscles from AMPK kinase dead (KD) and wild-type littermates with the PI3-kinase inhibitor LY-294002 demonstrated that PI3-kinase, but not AMPK, was essential for CNTF-stimulated glucose uptake. CNTF-stimulated glucose uptake and Akt phosphorylation were substantially reduced in obesity (high-fat diet and ob/ob) despite normal induction of gp130/AMPK signaling—effects also observed when treating myotubes with C2-ceramide.

CONCLUSIONS

CNTF acutely increases muscle glucose uptake by a mechanism involving the PI3-kinase/Akt pathway that does not require AMPK. CNTF-stimulated glucose uptake is impaired in obesity-induced insulin resistance and by ceramide.
Sex and Depot Differences in Adipocyte Insulin Sensitivity and Glucose Metabolism
Authors: Macotela Yazmin , Boucher Jeremie , Tran Thien T. , Kahn C. Ronald
Published: January 2009

OBJECTIVE

To investigate how insulin sensitivity and glucose metabolism differ in adipocytes between different fat depots of male and female mice and how sex steroids contribute to these differences.

RESEARCH DESIGN AND METHODS

Adipocytes from intra-abdominal/perigonadal (PG) and subcutaneous (SC) adipose tissue from normal, castrated, or steroid-implanted animals were isolated and analyzed for differences in insulin sensitivity and glucose metabolism.

RESULTS

Adipocytes from both PG and SC depots of females have increased lipogenic rates compared with those from males. In females, intra-abdominal PG adipocytes are more insulin-sensitive than SC adipocytes and more insulin-sensitive than male adipocytes from either depot. When stimulated by low physiological concentrations of insulin, female PG adipocytes show a robust increase in Akt and extracellular signal–related kinase (ERK) phosphorylation and lipogenesis, whereas male adipocytes show activation only at higher insulin concentrations. Adipocytes from females have higher mRNA/protein levels of several genes involved in glucose and lipid metabolism. After castration, adipocytes of male mice showed increased insulin sensitivity and increased lipogenic rates, whereas adipocytes of females demonstrate decreased lipid production. Increasing estrogen above physiological levels, however, also reduced lipid synthesis in females, whereas increasing dihydrotestosterone in males had no effect.

CONCLUSIONS

There are major sex differences in insulin sensitivity in adipose tissue, particularly in the intra-abdominal depot, that are regulated by physiological levels of sex steroids. The increased sensitivity to insulin and lipogenesis observed in adipocytes from females may account for their lower level of insulin resistance and diabetes risk despite similar or higher fat content than in males.

OBJECTIVE

Nicotinamide adenine dinucleotides (NAD+ and NADH) play a crucial role in cellular energy metabolism, and a dysregulated NAD+-to-NADH ratio is implicated in metabolic syndrome. However, it is still unknown whether a modulating intracellular NAD+-to-NADH ratio is beneficial in treating metabolic syndrome. We tried to determine whether pharmacological stimulation of NADH oxidation provides therapeutic effects in rodent models of metabolic syndrome.

RESEARCH DESIGN AND METHODS

We used β-lapachone (βL), a natural substrate of NADH:quinone oxidoreductase 1 (NQO1), to stimulate NADH oxidation. The βL-induced pharmacological effect on cellular energy metabolism was evaluated in cells derived from NQO1-deficient mice. In vivo therapeutic effects of βL on metabolic syndrome were examined in diet-induced obesity (DIO) and ob/ob mice.

RESULTS

NQO1-dependent NADH oxidation by βL strongly provoked mitochondrial fatty acid oxidation in vitro and in vivo. These effects were accompanied by activation of AMP-activated protein kinase and carnitine palmitoyltransferase and suppression of acetyl-coenzyme A (CoA) carboxylase activity. Consistently, systemic βL administration in rodent models of metabolic syndrome dramatically ameliorated their key symptoms such as increased adiposity, glucose intolerance, dyslipidemia, and fatty liver. The treated mice also showed higher expressions of the genes related to mitochondrial energy metabolism (PPARγ coactivator-1α, nuclear respiratory factor-1) and caloric restriction (Sirt1) consistent with the increased mitochondrial biogenesis and energy expenditure.

CONCLUSIONS

Pharmacological activation of NADH oxidation by NQO1 resolves obesity and related phenotypes in mice, opening the possibility that it may provide the basis for a new therapy for the treatment of metabolic syndrome.

OBJECTIVE

To determine whether middle-aged and older individuals with impaired fasting glucose (IFG), but no clinical evidence of cardiovascular disease, exhibit abnormal changes in proximal thoracic aortic stiffness or left ventricular (LV) mass when compared with healthy counterparts.

RESEARCH DESIGN AND METHODS

From the Multi-Ethnic Study of Atherosclerosis, 2,240 subjects with normal fasting glucose (NFG), 845 with IFG, and 414 with diabetes, all aged 45 to 85 years and without preexisting coronary artery disease, underwent MRI determinations of total arterial and proximal thoracic aortic stiffness and LV mass. The presence or absence of other factors known to influence arterial stiffness was assessed.

RESULTS

After adjustment for clinical factors known to modify arterial stiffness, proximal thoracic aortic stiffness was not increased in those with IFG compared with those with NFG (1.90 ± 0.05 versus 1.91 ± 0.04 10−3 mmHg−1, respectively, P = 0.83). After accounting for clinical factors known to influence LV mass, LV mass was increased in those with diabetes relative to those with NFG (150.6 ± 1.4 versus 145.8 ± 0.81 g, P < 0.0009) but not in those with IFG in comparison with NFG (145.2 ± 1.03 versus 145.8 ± 0.81 g, P = 0.56).

CONCLUSIONS

Middle-aged and older individuals with the pre-diabetes state of IFG do not exhibit abnormal proximal thoracic distensibility or LV hypertrophy relative to individuals with NFG. For this reason, an opportunity may exist in those with IFG to prevent LV hypertrophy and abnormal aortic stiffness that is observed in middle-aged and older individuals with diabetes.

Published: January 2009

OBJECTIVE

Metabolic syndrome (MetS) has been associated with increased prevalence of aortic valve calcium (AVC) and with increased progression of aortic stenosis. The purpose of this study was to determine whether MetS is associated with increased risks for the development of new (“incident”) AVC or for progression of established AVC as assessed by CT.

RESEARCH DESIGN AND METHODS

The relationships of MetS or its components as well as of diabetes to risks for incident AVC or AVC progression were studied among participants with CT scans performed at baseline and at either year 2 or year 3 examinations in the Multi-Ethnic Study of Atherosclerosis (MESA).

RESULTS

Of 5,723 MESA participants meeting criteria for inclusion, 1,674 had MetS by Adult Treatment Panel III criteria, whereas 761 had diabetes. Among the 5,123 participants without baseline AVC, risks for incident AVC, adjusted for time between scans, age, sex, race/ethnicity, LDL cholesterol, lipid-lowering medications, and smoking, were increased significantly for MetS (odds ratio [OR] 1.67 [95% CI 1.21–2.31]) or diabetes (2.06 [1.39–3.06]). In addition, there was an increase in incident AVC risk with increasing number of MetS components. Similar results were found using the International Diabetes Federation MetS criteria. Among the 600 participants (10.5%) with baseline AVC, neither MetS nor diabetes was associated with AVC progression.

CONCLUSIONS

In the MESA cohort, MetS was associated with a significant increase in incident (“new”) AVC, raising the possibility that MetS may be a potential therapeutic target to prevent AVC development.
Genome-Wide Scan for Linkage to Type 1 Diabetes in 2,496 Multiplex Families From the Type 1 Diabetes Genetics Consortium

Published: January 2009

OBJECTIVE

Type 1 diabetes arises from the actions of multiple genetic and environmental risk factors. Considerable success at identifying common genetic variants that contribute to type 1 diabetes risk has come from genetic association (primarily case-control) studies. However, such studies have limited power to detect genes containing multiple rare variants that contribute significantly to disease risk.

RESEARCH DESIGN AND METHODS

The Type 1 Diabetes Genetics Consortium (T1DGC) has assembled a collection of 2,496 multiplex type 1 diabetic families from nine geographical regions containing 2,658 affected sib-pairs (ASPs). We describe the results of a genome-wide scan for linkage to type 1 diabetes in the T1DGC family collection.

RESULTS

Significant evidence of linkage to type 1 diabetes was confirmed at the HLA region on chromosome 6p21.3 (logarithm of odds [LOD] = 213.2). There was further evidence of linkage to type 1 diabetes on 6q that could not be accounted for by the major linkage signal at the HLA class II loci on chromosome 6p21. Suggestive evidence of linkage (LOD ≥2.2) was observed near CTLA4 on chromosome 2q32.3 (LOD = 3.28) and near INS (LOD = 3.16) on chromosome 11p15.5. Some evidence for linkage was also detected at two regions on chromosome 19 (LOD = 2.84 and 2.54).

CONCLUSIONS

Five non–HLA chromosome regions showed some evidence of linkage to type 1 diabetes. A number of previously proposed type 1 diabetes susceptibility loci, based on smaller ASP numbers, showed limited or no evidence of linkage to disease. Low-frequency susceptibility variants or clusters of loci with common alleles could contribute to the linkage signals observed.

Two species of pinworms (Enterobiinae) were collected from fresh faeces of semi-wild orangutans Pongo abelii Lesson living in northern Sumatra (Indonesia). The female of Enterobius (Enterobius) buckleyi Sandosham, 1950 is redescribed. Lemuricola (Protenterobius) pongoi n. sp. is described on the basis of females (no males are available) and distinguished from L. (P.) nycticebi (Baylis, 1928) by cephalic and mouth morphology (head and teeth superstructures), body (9.85–15.46 mm) and tail (2.34–2.95 mm) length, smaller eggs (48–56 x 22–28 μm), longer vulva distance from anterior extremity (2.05–3.09 mm) and other features. Characteristic is the total body length/oesophagus length ratio (1: 15.3–22.0). Both nematode species were studied using scanning electron microscopy for the first time.
A checklist of helminth fauna of weatherfish, Misgurnus fossilis (Pisces, Cobitidae): state of the art, species list and perspectives of further studies
Authors: Popiołek M. , Kotusz J.
Published: January 2009

The helminth fauna of weatherfish (Misgurnus fossilis) in natural range is reviewed. Several helminth species reported in weatherfish are discussed with reference to host specificity and their geographical distribution. The current list of helminth parasites of the weatherfish includes 37 species. Most (15) are digenean trematodes, half of them being larval stages. Only one species of trematode — Allocreadium transversale is more specific parasite of weatherfish. Second largest group are Monogenea, with 10 species. Two of them (Gyrodactylus strelkovi and G. misgurni) are found only in the genus Misgurnus. Tapeworms (6 species) and Nematodes (6 species) are less numerous. No Acanthocephala, however, were ever found.

Authors: Morozinska-Gogol J.
Published: January 2009

The present paper summarized data on parasites of percid fishes (Actinopterygii: Percidae), such as pike-perch, European perch and ruffe from estuaries of the Polish coastal zone are listed, based on published records and long-term surveys carried out by the author. Parasites are listed alphabetically, separately for each host and for each parasite group with notes on their location on the host and geographical distribution (with references). A total of 41 species (taxa) of parasites were recorded on pike-perch Sander lucioperca (6 Ciliophora, 1 Myxozoa, 1 Monogenea, 11 Digenea, 4 Cestoda, 6 Nematoda, 5 Acanthocephala, 1 Mollusca, 1 Hirudinea, 4 Copepoda and 1 Branchiura). European perch, Perca fluviatilis, harboured 60 parasites (6 Ciliophora, 4 Myxozoa, 1 Monogenea, 18 Digenea, 9 Cestoda, 10 Nematoda, 5 Acanthocephala, 1 Mollusca, 1 Hirudinea, 4 Copepoda and 1 Branchiura). Ruffe Gymnocephalus cernuus featured 43 parasites (1 Microsporidia, 7 Ciliophora, 3 Myxozoa, 1 Monogenea, 13 Digenea, 5 Cestoda, 8 Nematoda, 2 Acanthocephala, 1 Mollusca and 2 Copepoda).
Consistency between marker‐ and genealogy‐based heritability estimates in an experimental stand ofProsopis alba(Leguminosae)

Published: January 2009

Prosopisrepresents a valuable forest resource in arid and semiarid regions. Management of promising species requires information about genetic parameters, mainly the heritability (h2) of quantitative profitable traits. This parameter is traditionally estimated from progeny tests or half‐sib analysis conducted in experimental stands. Such an approach estimatesh2from the ratio of between‐family/total phenotypic variance. These analyses are difficult to apply to natural populations of species with a long life cycle, overlapping generations, and a mixed mating system, without genealogical information. A promising alternative is the use of molecular marker information to infer relatedness between individuals and to estimateh2from the regression of phenotypic similarity on inferred relatedness. In the current study we comparedh2of 13 quantitative traits estimated by these two methods in an experimental stand ofP. alba, where genealogical information was available. We inferred pairwise relatedness by Ritland's method using six microsatellite loci. Relatedness and heritability estimates from molecular information were highly correlated to the values obtained from genealogical data. Although Ritland's method yields lowerh2estimates and tends to overestimate genetic correlations between traits, this approach is useful to predict the expected relative gain of different quantitative traits under selection without genealogical information.
Developmental disaster1: A novel mutation causing defects during vegetative and inflorescence development in maize (Zea mays, Poaceae)
Authors: Phillips Kimberly A. , Skirpan Andrea L. , Kaplinsky Nicholas J. , McSteen Paula
Published: January 2009

Axillary meristems, which give rise to branches and flowers, play a critical role in plant architecture and reproduction. To understand how axillary meristems initiate, we have screened for mutants with defects in axillary meristem initiation to uncover the genes controlling this process. These mutants, called the barren class of mutants in maize (Zea mays), have defects in axillary meristem initiation during both vegetative and reproductive development. Here, we identify and characterize a new member of the barren class of mutants named Developmental disaster1 (Dvd1), due to the pleiotropic effects of the mutation. Similar to the barren mutants, Dvd1 mutants have fewer branches, spikelets, florets, and floral organs in the inflorescence due to defects in the initiation of axillary meristems. Furthermore, double mutant analysis with teosinte branched1 shows that dvd1 also functions in axillary meristems during vegetative development. However, unlike the barren mutants, Dvd1 mutants are semidwarf due to the production of shorter internodes, and they produce leaves in the inflorescence due to the outgrowth of bract leaf primordia. The suite of defects seen in Dvd1 mutants, together with the genetic interaction of Dvd1 with barren inflorescence2, suggests that dvd1 is a novel regulator of axillary meristem and internode development.
Product specification and agribusiness chain coordination: introducing the coordination differential concept
Authors: de Moura Altair Dias , Martin Sandra , Mollenkopf Diane
Published: January 2009

As customers increasingly demand more specific products, firms are adopting new business approaches to satisfy customers and cope with competition. Efforts to satisfy ever more demanding markets appear to be associated with increased chain coordination, yet the relationship between these two factors is unclear. This research addresses the factors that affect chain coordination, focusing on the management of business processes to meet product specifications for customers. Five fresh meat New Zealand chains were the focus of multiple case study research. Results suggest that chains use different strategies and coordination mechanisms to deliver desired product specifications. More important, while product specifications are related to chain coordination as expected, the relationship is mediated by the coordination differential—the type and amount of effort that firms employ in their business processes to achieve the desired specifications. The nature and implication of the coordination differential concept are discussed. [L140, L150, L170]. © 2009 Wiley Periodicals, Inc.
Life‐transforming congregations

Published: January 2009

Hundreds of studies have shown that people who are actively involved in faith communities have less cardiovascular disease, live significantly longer and enjoy higher levels of wellbeing. But which aspects impact lives in healthy ways? This paper identifies six ministry essentials with very strong links to emotional and spiritual wellbeing, based on surveying over 26,000 worshippers in 174 church congregations. We also list seven of the most important things that church communities can do to impact more lives. In addition, we discovered a very strong link between emotional aliveness in church communities and their life‐changing impact. Copyright © 2009 John Wiley & Sons, Ltd.

The dynamics of energy storage for paraffin wax in cylindrical containers
Authors: Menon A. S. , Weber M. E. , Mujumdar A. S.
Published: January 2009

Heat transfer rates were measured to a commercial paraffin wax undergoing freezing and melting in vertical cylindrical containers. Circular, square and axially‐partitioned cylinders were used. Natural convective motions were followed using tracer particles in a visual study of melting. Freezing fluxes were well predicted by a quasi‐steady conduction model. Melting fluxes were enhanced by natural convection. A melting model employing an effective thermal conductivity predicted melting fluxes satisfactorily.
Stochastic modeling of bubble formation on the grid in a gas‐solid fluidized bed
Authors: Ho Tho‐Ching , Yutani N. , Fan L. T. , Walawender Walter P.
Published: January 2009

Bubble formation on the grid in a three‐dimensional fluidized bed was studied by means of a mini‐capacitance probe coupled with the on‐line correlation technique. Experiments were carried out in fluidized beds with relatively shallow bed heights of 50, 80 and 100 mm. The present study has confirmed the well‐known observation that bubbles detach from the end of a jet with a formation frequency of about 19 Hz. The stochastic process proposed, more specifically, a renewal counting process corresponding to the gamma distributed inter‐arrival times, has been found to describe the process of bubble formation well.
Dynamic analysis of adsorption on bidisperse porous catalysts
Authors: DoG'U Gülşen , Ercan Cemal
Published: January 2009

In a variety of catalytic processes dealing with porous catalysts, bidisperse solids arc used. In such systems, it is important to know the adsorption rate together with the diffusion rate in the macro and micropores of the porous solid. In this work, the Dog'u‐Smith (1975) single pellet pulse response method has been used for the simultaneous evaluation of the adsorption and the macro and micropore diffusion parameters in bidisperse porous catalysts. It has been shown that the method succesfully can be applied for fast and accurate evaluation of these parameters. Equations relating the adsorption and diffusion parameters to the measurable properties of the response peak have been derived for a bidisperse pellet.

The method experimentally was tested for ethylene adsorption on α‐alumina at 45°C and atmospheric pressure. For a pellet of total porosity 0.73 and macroporosity 0.32, the effective macro and micropore diffusivities and the adsorption equilibrium constant were determined as 0.0334 cm2/s, 8.9×106 cm2/s and 25 cm3/g, respectively.
Tar sand extractions with microemulsions: I‐the dissolution of light hydrocarbons by microemulsions using 2‐butoxyethanol and diethylmethylamine as cosurfactants
Authors: Desnoyers Jacques E. , Quirion François , HÉTu Daniel , Perron GÉRald
Published: January 2009

For oil sand extractions with microemulsions it is important to disperse large quantities of light hydrocarbons in an aqueous medium. Fundamental studies on the properties of 2‐butoxyethanol (BE) and diethylmethylamine (Et2McN) in water suggest that these two liquids could be more effective cosurfactants than the usual alcohols used for this purpose. The phase diagrams of microemulsions using BE and Et2MeN as cosurfactants, combined with typical ionic and non‐ionic surfactants and typical aliphatic and aromatic hydrocarbons, were therefore investigated and compared with microemulsions based on n‐butanol. Although the phase diagrams depend significantly on the nature of the surfactant and of the oil, the monophasic region generally increases with the cosurfactant in the order n‐butanol < Et2McN < BE. With the active mixture BE‐cetyltrimethylammonium bromide, temperature has little effect on the phase diagram and NaCl generally destabilizes the microemulsion.
Catalytic hydrogenation and asphaltene conversion of athabasca bitumen
Authors: Ternan Marten
Published: January 2009

Bitumen from the Athabasca Oil Sand deposits was hydrogenated using three MoO3‐CoO catalysts having markedly different median pore diameters. The results were interpreted in terms of the reaction rates being controlled by the rate of pore diffusion of asphaltene micelles. Catalysts with larger pore diameters produced higher conversions per unit surface area. However, the accessible catalyst surface area per unit volume of reactor decreased as the catalyst pore diameter increased. The decreasing surface area was responsible for the general decrease in conversion with increasing pore diameter. Higher conversions are obtained with higher surface area catalysts having smaller pores, even though pore diffusion controls the rate of reaction.
