Increased allocation of adult-acquired carbohydrate to egg production results in its decreased allocation to sex pheromone production in mated females of the moth Heliothis virescens
Authors: Foster Stephen , Anderson Karin , Harmon Jason 
Published: November 2013

Summary
Females of most species of moths produce a volatile sex pheromone that attracts conspecific males over distance. In females of the polyandrous moth Heliothis virescens, feeding on carbohydrate (e.g., nectar) supplies precursor, via hemolymph trehalose, for both sex pheromone and egg production. With limited carbohydrate acquisition these two reproductive physiologies might compete for hemolymph trehalose, resulting in an allocation deficit to one. Using virgin and mated females, which have low and high egg maturation rates, respectively, we fed females a limited diet of 13C-labeled glucose daily and, using mass isotopomer distribution analysis, determined allocations of adult-acquired carbohydrate (AAC) to newly synthesized pheromone and ovarian and egg fats, our proxies for allocation to egg production. With increased number of feeds, AAC enrichment of hemolymph trehalose increased, as expected. This led to mated females increasing their proportional allocation of AAC to ovarian and egg fats, but decreasing their proportional allocation of AAC to pheromone production. By contrast, virgins increased their proportional allocation of AAC to pheromone production with increased feeds, consistent with increasing AAC enrichment of hemolymph trehalose. These results show that with limited AAC intake, enhanced egg maturation in mated females results in reduced AAC allocation to pheromone production; this does not occur in virgins because of their lower egg maturation rate. This physiological competition for AAC corresponded with decreased pheromone production in mated moths to levels unlikely to attract mates. Therefore, the availability/allocation of AAC may be a proximate mechanism underlying the incidence of polyandry in this and other species of moths.

AIM: To evaluate the plasma level of circulating heptocyte growth factor (HGF) in patients with comorbidity of post-infarction chronic heart failure (CHF), type 2 diabetes mellitus (T2DM) and obesity. We also aimed to assess possible correlations between HGF levels and parameters of carbohydrate and lipid metabolism, as well as myocardial functional characteristics and classic biochemical severity markers for CHF.17Сахар ный диабет КардиологияСахарный диабет. 2013;(2):17-25
MATERIALS AND METHODS: We enrolled 100 patients for participation in this study, including the following subgroups: 20 individuals with- out cardiovascular and glycemic disorders, 30 patients with CHF, 25 patients with CHF/T2DM comorbidity and 25 diabetic patients with no signs of heart failure. Quantitative plasma HGF analysis was performed with enzyme-linked immunosorbent assay (ELISA).
RESULTS: Plasma HGF was elevated both in patients with CHF and T2DM as measured against healthy control group. The elevation was most prominent in patients with CHF/T2DM comorbidity and was found to correlate with HbA1c level (r=0.52, p=0.03). Plasma HGF also correlated with BMI (r=0.42, p=0007) in a unified study group, though we observed no statistically significant difference between subgroups with a trend toward higher HGF in obese patients with CHF/T2DM comorbidity (626.1?254.1 pg/ml vs 742.0?210.7 pg/ml respectively; p 0.05). Interestingly, plasma HGF was also significantly higher in controls with BMI 30 km/m2 (324.1?107.7 pg/ml vs 436.9?112.3 pg/ml, p=0.03).Circulating HGF correlated with plasma levels of N-terminal fragment of B-type natriuretic peptide (NT-proBNP) and such structural and functional myocardial characteristics as left atrial size and maximum volume along with left ventricular ejection fraction (EF), end-diastolic volume (EDV) and end-diastolic dimension (EDD).
CONCLUSION: These findings suggest that HGF may potentially serve as a prediction marker for unfavorable myocardial remodeling and poor prognosis in CHF patients with T2DM and obesity, though this possibility should be further investigated in follow-up studies.

Zusammenfassung:
Der Beitrag stellt einführend Open Educational Resources (OER) als ein mögliches zukünftiges Handlungsgebiet für wissenschaftliche Bibliotheken vor. Dazu werden die Grundlagen des OER-Begriffs erläutert und eine 2012 an der Universität Strathclyde (Glasgow) durchgeführte Studie zur Beteiligung von Bibliotheken und Bibliothekaren an OER-Projekten vorgestellt, die zum Ergebnis kommt, dass diese wichtige Kompetenzen in OER-Projekte einbringen können, was allerdings sowohl seitens der Bibliotheken als auch seitens vieler OER-Projekte noch nicht ausreichend bekannt sei. Nach Ansicht des Autors bietet OER wissenschaftlichen Bibliotheken die Chance, noch stärker am akademischen Lehrprozess zu partizipieren als bisher. Dabei entstehen neue Herausforderungen in den Bereichen Bewusstseinsbildung, Metadatenstandardisierung, Bereitstellung von OER, Herstellung von OER und OER-Management.

Published: November 2013

Abstract
Glucagon is a hormone with important effects on blood glucose regulation. This study has utilized the stable glucagon receptor antagonists, desHis1Pro4Glu9-glucagon and desHis1Pro4Glu9(Lys12PAL)-glucagon, to evaluate the effects of sustained inhibition of glucagon receptor signalling in normal mice. Twice-daily injection of either analogue for 10 days had no effect on food intake, body weight and non-fasting plasma glucose concentrations. However, insulin levels were significantly raised (p<0.05 to p<0.01) from day 3 onwards in desHis1Pro4Glu9-glucagon mice. After 10 days, glucose tolerance was improved (p<0.05) in desHis1Pro4Glu9-glucagon treated mice. Glucose-mediated insulin secretion and circulating cholesterol levels were significantly (p<0.05 to p<0.01) decreased in both treatment groups. Importantly, the effects of glucagon to increase blood glucose and insulin concentrations were still annulled on day 10. Insulin sensitivity was almost identical in all groups of mice at the end of the study. In addition, no changes in pancreatic insulin and glucagon content or islet morphology were observed in either treatment group. Finally, acute injection of desHis1Pro4Glu9-glucagon followed by a 24-h fast in treatment naïve mice was not associated with any hypoglycaemic episodes. These data indicate that peptide-based glucagon receptor antagonists represent safe and effective treatment options for type 2 diabetes.

Abstract
Ethylene-vinyl alcohol copolymers (EVOH), with appropriate barriers and processability, can be chemically modified through vinyl alcohol units. Amides and polyamides based on condensation reactions of adipoyl chloride and hexamethylenediamine were grafted onto EVOH. Grafting was characterized by contact angle measurement, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), nuclear magnetic resonance spectroscopy (NMR) and scanning electron microscopy (SEM). Amide peaks at 3302 cm-1 corresponding to –NH bond stretching and the absorption of HN-CH2 at 7.8 ppm, were observed from ATR-FTIR and NMR, respectively, as a result of grafting. SEM showed the formation of amide structures as bundles, agglomerates and needle-like particles. Differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA) showed considerable changes in onset of melt temperature, crystallinity and various transitions in grafted EVOH, showing an effective alteration in the physical properties compared with the virgin resin. Nylon grafted EVOH can be considered as a potential compatibilizer in polyethylene (PE)/polyamide blends via increasing interactions at the interface.
Exposure to leachate from municipal battery recycling site: implication as key inhibitor of steroidogenic enzymes and risk factor of prostate damage in rats

Abstract
Few or no studies have measured the effect of short- and long-term exposure to industrial leachate. Mature male Wistar strain albino rats (175–220 g) underwent sub-chronic exposure to leachate from the Elewi Odo municipal battery recycling site (EOMABRL) via oral administration for a period of 60 days at different doses (20%, 40%, 60%, 80%, and 100%) per kilogram of body weight to evaluate the toxic effects of the leachate on male reproductive function using steroidogenic enzymes and biomarkers of prostate damage. Control groups were treated equally but were given distilled water instead of the leachate. After the treatment periods, results showed that the treatment induced systemic toxicity at the doses tested by causing a significant (p<0.05) loss in absolute body weight and decline in growth rate. There was a marked significant decrease (p<0.05) in testicular activities of Δ5-3β-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase. Conversely, the activity of prostatic acid phosphatase, a key marker enzyme for prostrate damage was significantly (p<0.05) elevated in the treated rats. Similarly, the administration of EOMABRL significantly (p<0.05) exacerbated the activity of total acid phosphatase with concomitant increase in the activity of prostatic alkaline phosphatase. These findings conclude that exposure to leachate from a battery recycling site induces sub-chronic testicular toxicity by inhibiting key steroidogenic enzymes and activating key markers linked with prostate damage/cancer in rats.
par-1, Atypicalpkc, and PP2A/B55sur-6Are Implicated in the Regulation of Exocyst-Mediated Membrane Trafficking inCaenorhabditis elegans

Published: November 2013

AbstractThe exocyst is a conserved protein complex that is involved in tethering secretory vesicles to the plasma membrane and regulating cell polarity. Despite a large body of work, little is known how exocyst function is controlled. To identify regulators for exocyst function, we performed a targeted RNA interference (RNAi) screen in Caenorhabditis elegans to uncover kinases and phosphatases that genetically interact with the exocyst. We identified seven kinase and seven phosphatase genes that display enhanced phenotypes when combined with hypomorphic alleles of exoc-7 (exo70), exoc-8 (exo84), or an exoc-7;exoc-8 double mutant. We show that in line with its reported role in exocytotic membrane trafficking, a defective exoc-8 caused accumulation of exocytotic soluble NSF attachment protein receptor (SNARE) proteins in both intestinal and neuronal cells in C. elegans. Down-regulation of the phosphatase protein phosphatase 2A (PP2A) phosphatase regulatory subunit sur-6/B55 gene resulted in accumulation of exocytic SNARE proteins SNB-1 and SNAP-29 in wild-type and in exoc-8 mutant animals. In contrast, RNAi of the kinase par-1 caused reduced intracellular green fluorescent protein signal for the same proteins. Double RNAi experiments for par-1, pkc-3, and sur-6/B55 in C. elegans suggest a possible cooperation and involvement in postembryo lethality, developmental timing, as well as SNARE protein trafficking. Functional analysis of the homologous kinases and phosphatases in Drosophila median neurosecretory cells showed that atypical protein kinase C kinase and phosphatase PP2A regulate exocyst-dependent, insulin-like peptide secretion. Collectively, these results characterize kinases and phosphatases implicated in the regulation of exocyst function, and suggest the possibility for interplay between the par-1 and pkc-3 kinases and the PP2A phosphatase regulatory subunit sur-6 in this process.
Performance of High-Throughput Sequencing for the Discovery of Genetic Variation Across the Complete Size Spectrum
Authors: Pang Andy Wing Chun , MacDonald Jeffrey R , Yuen Ryan K C , Hayes Vanessa M , Scherer Stephen W 
Published: November 2013

Abstract
We observed that current high-throughput sequencing approaches only detected a fraction of the full size-spectrum of insertions, deletions, and copy number variants compared with a previously published, Sanger-sequenced human genome. The sensitivity for detection was the lowest in the 100- to 10,000-bp size range, and at DNA repeats, with copy number gains harder to delineate than losses. We discuss strategies for discovering the full spectrum of genetic variation necessary for disease association studies.

Published: November 2013

AbstractChlorine-containing organic compounds (Cl-VOC) require special attention due to their distinct toxicity, high stability and persistence in the environment. Removal of Cl-VOC by catalytic oxidation over a wide variety of catalysts has been presented in literature. This paper reviews the state of the art in this subject, including different model compounds, nature of catalysts, and oxidation activity. Catalyst selectivity (CO2 vs. CO and HCl vs. Cl2), by-products formation and the causes of deactivation are also analyzed as the most important factors in the catalyst selection for practical applications.

Published: November 2013

Ralstonia solanacearum causes bacterial wilt of solanaceous crop plants including brinjal, a most devastating disease in humid tropic. A survey was conducted on the status of bacterial wilt incidence and severity in major brinjal growing areas and to characterize the isolates of R. solanacearum causing bacterial wilt of brinjal in Bangladesh. The wilt incidence was recorded maximum (22.52) in Rangpur followed by Jessore (20.56) and Panchagarh (20.0) while the lowest wilt incidence was recorded in Jamalpur (6.12). On the contrary, the wilt severity was recorded highest (4.00) in Jhinaidah and the lowest (2.80) was recorded in Jamalpur followed by Jessore (2.93) at the time of survey. The isolates of R. solanacearum were obtained from different locations surveyed were arranged in seven groups based on the location. Grams staining and Potassium hydroxide solubility test revealed that all groups of R. solanacearum isolates are gram negative. The isolates of R. solanacearum fermented four basic sugars (Dextrose,sucrose, manitol and lactose). These results of all biochemical tests in combination with the pathogenicity test confirmed the isolates were R. solanacearum causing bacterial wilt of brinjal. All groups of R. solanacearum isolates were found virulent producing pink or light red color or characteristic red center and whitish margin on TZC medium after 24 hours of incubation. On the biovar test clearly revealed that all groups of R. solanacearum isolates oxidized disaccharides (Sucrose, lactose, and maltose) and sugar alcohols (manitol, sorbitol and dulcitol) within 3-5 days and confirmed biovar as III.Pathogencity test on tomato and chilli indicating wide host range of R. solanacearum isolates and categorized them in race 1. Therefore, it may beconfirmed that R. solanacearum causing bacterial wilt of brinjal in Bangladesh belong to Biovar III and Race 1.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16744 Progress.

Published: November 2013

An experiment was conducted to study the efficacy of washing (control and 5% hydrogen peroxide) and post harvest treatments (control, hot water treatment, wrapping with unperforated and perforated plastic bags, wrapping with brown paper bag and wrapping with aluminum foil) on shelf life and quality of oyster mushroom. Postharvest treatments caused significant effects to influence weight loss, dry matter and protein contents, disease incidence and shelf life of mushroom. At the 7th day of storage, the highest weight loss (98.08%) was recorded in the untreated mushrooms, whereas the lowest weight loss (33.62%) was observed in mushrooms wrapped in unperforated plastic bag. Protein content was observed to be higher (28.98%) in mushrooms wrapped with unperforated plastic bag followed by perforated plastic bag (25.00%) at the 5th day of storage. Protein content declined dramatically in mushrooms held atambient conditions. The lowest protein content (2.97%) was recorded in the untreated mushrooms at the 7th day of storage. Unwashed mushrooms held atambient temperature had the highest incidence of disease. The longest shelf lifeof 6 days was recorded in mushrooms wrapped in unperforated plastic bag,whereas the shortest shelf life (3 days) was found in the untreated mushrooms.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16745 Progress.

Published: November 2013

A total of 29 lines of F4 population of rice along with their parents Binadhan-5 (high yielding and salt susceptible) and Harkuch (salt tolerant landrace) were evaluated for salt tolerance at the reproductive stage with EC 6 dS/m following IRRI standard protocol. High heritability coupled with high genetic advance was observed in plant height in salinized and non-salinized conditions. High heritability along with high genetic advance was also found in number of filled grains/plant in saline condition. These characters were under additive gene control and selection for salt tolerance might be effective. Number of filled grains/plant showed significant positive correlation with grain yield/plant. Path analysis revealed that number of filled grains/plant had positive and maximum direct effect on grain yield/plant. Therefore, number of filled grains/plant should be given the importance in selection of rice lines under saline condition.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16746 Progress.

Published: November 2013

A participatory stakeholder-based approach was employed to improve the quality of exportable fish and prawn landed in Kulierchar of Kishoregonj through reduction of the post harvest loss and its impacts were assessed. Primary data revealed that wet fish were minimally washed with clean water immediately after harvest. Ice boxes were not used in any stages from harvest to processing plants. Bamboo split baskets were mostly used to keep or carry fish. Landed fish were found to be dispersed on plastic mat or polythene paper kept on earthen floor of the wholesaler shed, called Arat. Icing of individual catch soon after harvest was very insignificant, ranging from 2  15 % only. Prawn were found to be iced during transport to landing center at little higher rate (32%), but most of the other fish were not significantly iced during transport to landing center. Primary awareness of the beneficiaries on quality deterioration of fish was assessed and the impacts of participatory awareness development tools (PRA and RRA, personal contacts, brain storming and awareness development training) on export, income, nutrition and improved handling of landed exportable prawn/fish were re-assessed. Efficacy of such measures to improve the situation were monitored for sixteen months. Awareness in terms of benefit of good practices was high in factory technicians. Other stakeholders had very shallow or poor knowledge on use of improved handling and processing of fish. Participatory tools employed in this study was found to be effective in developing awareness of stakeholders in different value chains of wet fish handling and distribution and reducing post-harvest loss.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16757 Progress.

Authors: Hodkinson Trevor R. , de Cesare Mariateresa , Barth Susanne 
Published: November 2013

• Premise of the study: We developed nuclear simple sequence repeat (SSR) markers for the characterization of the biomass crop Miscanthus, especially M. sacchariflorus, M. sinensis, and M. ×giganteus, and tested for cross‐species amplification.• Methods and Results: Twenty‐nine SSR markers (di‐ and tetranucleotide repeats) were developed from DNA sequences obtained from 192 clones from an enriched genomic library of M. sinensis. All markers were successfully amplified in M. sacchariflorus, M. sinensis, and M. ×giganteus, and 19 amplified across a broad range of Miscanthus species. Polymorphism information content and expected heterozygosity values (19 locus sample) were 0.88 and 0.89, respectively, for M. sinensis, 0.48 and 0.54 for M. sacchariflorus, and were the lowest in M. ×giganteus (0.33, 0.41). Thirteen out of 19 primer pairs showed cross‐species amplification in non‐Miscanthus sensu stricto taxa.• Conclusions: The new set of 29 SSR markers will be of high value for characterizing Miscanthus germplasm collections, for prebreeding, and for assessing variation in natural populations.
