The Importance of Validating the Duration of Fishing Trips: Are Harvest Rates from On-Site Recreational Fishing Surveys Unbiased?
Authors: Steffe Aldo S. , Murphy Jeffrey J. 
Published: February 2011

Abstract
Harvest rates are often used as indicators of fishing quality and in the estimation of total harvest in some on-site survey designs. The unbiased estimation of harvest and fishing effort is critical for calculating accurate harvest rates. On-site survey designs allow survey clerks to validate harvest data directly. This harvest validation assumes that the level of intentional deception by fishers is relatively small. Therefore, validating angler-generated estimates of trip duration is important because this can provide evidence that harvest rates and other variables derived from effort data are also unbiased. Also, one can partition effort and harvest within trips to calculate directed harvest rates for different target species or species groups, knowing that the angler-generated estimates of total trip length are not contributing systematically to any bias in the directed harvest rates. We examined the accuracy of trip duration estimates reported by trailer boat fishers in the marine waters of New South Wales, Australia. Comparing these angler-generated estimates with observed records of actual trip duration demonstrated that the angler-generated estimates were empirically unbiased both for estimates in terms of party-hours and those in terms of angler-hours. These findings have several implications for the interpretation and analysis of survey results. We therefore recommend that angler-generated estimates of trip duration be validated for different recreational fisheries; moreover, reliable reference points should be incorporated into all interview protocols because they can minimize the bias in self-reported estimates of fishing effort. The validation of trip duration and harvest rate data are vital for convincing fisheries managers and stakeholders that surveys can provide reliable information about a fishery.
The Economic Impact of Saltwater Sportfishing Harvest Restrictions in Alaska: An Empirical Analysis of Nonresident Anglers
Authors: Lew Daniel K. , Seung Chang K. 
Published: February 2011

Abstract
Saltwater sportfishing is a popular activity for visitors to Alaska. In this paper, a stated-preference model of saltwater sportfishing participation is used to generate estimates of the changes in participation resulting from changes in harvest limits for three primary recreational target species in Alaska saltwater fisheries: Pacific halibut Hippoglossus stenolepis, Chinook salmon Oncorhynchus tshawytscha, and coho salmon O. kisutch. These estimates are then used in a state-level computable general equilibrium (CGE) model to generate estimates of the economic impacts of harvest policies. We find that the impacts of changes in nonresident anglers' expenditures are smaller than those from a social accounting matrix model and that many of the impacts from an increase in expenditures leak out of state owing to Alaska's heavy dependence on imports of goods and services from the rest of the United States. Moreover, changes to harvest limits appear to have a small effect on the Alaska economy, at least in comparison with the overall size of that economy.
Presence and Attunement in Health Care: A View from Infancy Research
Authors: Trout Michael 
Published: February 2011

In the nuanced exchange between mother and baby—with its exquisite attunement, which we now know creates neurobiological changes in both parties—we see a metaphor for the therapeutic relationship in health care. To the extent that the mother is fully present, the infant is not only regulated in the moment, but also learns to self-regulate. What is the power of the nurse's presence to heal and to increase the patient's participation in healing? And where does a nurse reach for this critical health care tool? I did not know that I was allowed … to donate my presence, my attention, my regard. (Charon, 2006, p. 34)

Authors: Rosalem W. , Rescala B. , Teles R.P. , Fischer R.G. , Gustafsson A. , Figueredo C.M. 
Published: February 2011

Background: Our goal was to examine differences in clinical, microbiologic, and immunologic responses to non‐surgical mechanical therapy in patients with generalized chronic periodontitis (GCP) and generalized aggressive periodontitis (GAgP).Methods: Twenty patients with GCP and 14 patients with GAgP were evaluated. Clinical data, gingival crevicular fluid (GCF), and subgingival plaque samples were collected at baseline and 3 months after non‐surgical periodontal treatment. Levels of 40 subgingival species were measured using checkerboard DNA‐DNA hybridization. GCF interleukin (IL)‐1β, ‐4, and ‐8 and interferon‐γ (IFN‐γ) were analyzed using a multiplexed bead immunoassay, and elastase activity was measured using an enzymatic assay. The significance of changes with time was examined using the Wilcoxon rank sum test. Changes in clinical, microbiologic, and immunologic parameters after therapy were compared between groups using the Mann‐Whitney U test.Results: After periodontal therapy, we found significant improvements for all clinical parameters in both groups. We also observed significant reductions in elastase activity in shallow and deep sites from the GAgP group and in deep sites from the GCP group. Microbiologic data showed significant reductions in proportions of orange and red complexes and an increase in proportions of Actinomyces species in both clinical groups. When the clinical, microbiologic, and immunologic responses after therapy were compared between groups, only minor differences were found.Conclusion: This study fails to show any significant differences between severe forms of GCP and GAgP in response to non‐surgical periodontal treatment.

Published: February 2011

Background: Visfatin is a pleiotropic mediator that acts as growth factor, cytokine, and enzyme involved in energy including nicotinamide adenine dinucleotide metabolism and was recently demonstrated to exert several proinflammatory functions. The purpose of this study is to determine the presence of visfatin in gingival crevicular fluid (GCF) and serum samples and to find out their association, if any.Methods: At the beginning of the study, 40 individuals (20 males and 20 females; age range: 23 to 53 years) were selected and divided into three groups based on the gingival index, probing depths, clinical attachment levels, and radiologic parameters (bone loss). Group 1 (10 patients with healthy periodontium; age range: 25‐36 years), group 2 (15 patients with gingivitis; age range: 25‐36 years), and group 3 (15 patients with chronic periodontitis; age range: 23‐53 years) GCF (by microcapillary pipettes) and serum (by venipuncture) samples were collected to estimate levels of visfatin using an enzyme‐linked immunosorbent assay kit.Results: Mean visfatin concentrations increased in GCF and serum with the severity of disease from healthy to gingivitis to periodontitis groups and differed significantly (P <0.05). However, it was found that GCF values were higher than serum values. The highest to lowest visfatin concentrations were found in groups 3 through 1, respectively. Visfatin in GCF and serum correlated positively with periodontal parameters in the chronic periodontitis group.Conclusions: The results suggest that GCF and serum visfatin concentrations increase with the severity of periodontal disease. Hence, visfatin values were considered an inflammatory marker in periodontal disease in GCF and serum. Visfatin also deserves further consideration as a therapeutic target.

Published: February 2011

Background: Although a range of biologic and pharmacologic activities of luteolin has been reported, little is known about its potential as an agent to treat periodontal disease. In the present study, we investigated whether luteolin could downregulate the production of proinflammatory mediators in murine macrophage‐like RAW264.7 cells stimulated with lipopolysaccharide (LPS) from Prevotella intermedia (Pi), a major cause of inflammatory periodontal disease, and we attempted to elucidate the possible mechanisms of action.Methods: LPS was prepared from lyophilized Pi ATCC 25611 cells by the standard hot phenol‐water method. Culture supernatants were collected and assayed for nitric oxide (NO) and interleukin (IL)‐6. We used real‐time polymerase chain reaction to detect inducible NO synthase (iNOS) and IL‐6 mRNA expression. iNOS expression, phosphorylation of JNK and p38, IκB‐α degradation, nuclear translocation of nuclear factor‐kappaB (NF‐κB) subunits, and signal transducer and activator of transcription‐1 (STAT1) phosphorylation were characterized via immunoblotting. DNA‐binding of NF‐κB was also analyzed.Results: Luteolin strongly suppressed the production of NO and IL‐6 at both gene transcription and translation levels in Pi LPS‐activated RAW264.7 cells. Mitogen‐activated protein kinase pathways were not involved in the inhibition of Pi LPS‐induced NO and IL‐6 release by luteolin. Luteolin did not reduce NF‐κB transcriptional activity at the level of IκB‐α degradation. Luteolin blocked NF‐κB signaling through inhibition of nuclear translocation and DNA binding activity of NF‐κB p50 subunit and suppressed STAT1 signaling.Conclusions: Although further research is encouraged to clarify the detailed mechanism of action, flavonoid luteolin may contribute to blockade of the host‐destructive processes mediated by these two proinflammatory mediators and could have potential use in the treatment of inflammatory periodontal disease.

Association of Decreased Glomerular Filtration Rate with Racial Differences in Survival after Acute Myocardial Infarction
Authors: Wetmore James B. , Sankaran Sundar , Jones Philip G. , Reid Kimberly J. , Spertus John A. 
Published: February 2011

Summary

Background and objectives
African-American race and decreased kidney function have been associated with higher mortality after acute myocardial infarction (AMI). However, whether there are racial differences in the prevalence or prognostic importance of renal insufficiency in AMI is unknown.

Design, setting, participants & measurements
Among 1847 AMI patients enrolled in the multicenter Prospective Registry Evaluating Myocardial Infarction Event and Recovery (PREMIER) study, estimated glomerular filtration rate (eGFR) was used to stratify prognosis and to examine potential interactions among eGFR, race, and mortality. Multivariable proportional hazards regression was used to examine the effect of race and eGFR on 3.5-year all-cause mortality.

Results
Race and eGFR were significantly associated with mortality. After adjustment for eGFR alone, differences in mortality by race were substantially attenuated (unadjusted hazard ratio [HR] for African Americans = 1.56 [95% confidence interval {CI}= 1.2 to 2.1]; eGFR-adjusted HR = 1.32 [95% CI = 0.99 to 1.75]). A similar magnitude of attenuation in racial differences in survival was observed after adjustment for all covariates except eGFR (HR = 1.29 [95% CI = 0.96 to 1.72]). A final model adjusting for all covariates only slightly attenuated the association further. No interaction between race and eGFR was detected.

Conclusions
Renal insufficiency, which may represent chronic kidney disease, is a prognostically important comorbidity in African Americans after AMI. However, the effect of decreased eGFR on mortality is comparable between races, suggesting that preventing renal insufficiency in African Americans could be an important target to reduce racial disparities in post-AMI survival.

Published: February 2011

Summary

Background and objectives
In living-donor kidney transplantation, various donor factors, including gender, age, and baseline kidney function, predict allograft function and recipient outcomes after transplantation. Because higher phosphorus is predictive of vascular injury in healthy adults, the effect of donor phosphorus levels on recipient renal function after transplantation was investigated.

Design, setting, participants, and measurements
Phosphorus levels in 241 living donors were analyzed from a 7-year period, and recipient renal function and acute rejection at 1 year posttransplantation were examined controlling for other influencing factors, including multiple donor variables, HLA matching, and acute rejection.

Results
Female and African-American donors had significantly higher phosphorus levels predonation. By multivariable analysis, higher donor phosphorus correlated with higher recipient serum creatinine (slope = 0.087, 95% confidence interval [CI]: 0.004 to 0.169, P = 0.041) and lower recipient estimated GFR (slope = −4.321, 95% CI: −8.165 to −0.476, P = 0.028) at 12 months. Higher donor phosphorus also displayed an independent correlation with biopsy-proven acute rejection and delayed or slow graft function after transplantation.

Conclusions
In a cohort of living kidney donors, higher donor phosphorus correlated with female gender and African-American ethnicity and was an independent risk factor for early allograft dysfunction after living-donor kidney transplantation.

Published: February 2011

AbstractThe purpose of this study was to conduct a clinical and pathologic review of endometrial cancers diagnosed and surgically treated in our institution to evaluate results of treatment in relation to current international recommendations. We retrospectively evaluated the clinical history, treatment and follow-up of patients with histologically confirmed endometrial cancer treated in Faculty Hospital Nitra, Slovakia from 1990 to 2005. Data were abstracted regarding tumor histology, grade, age, parity, stage, diabetes, use of oral contraceptives, BMI, survival and treatment modalities including surgery, radiation therapy, chemotherapy, hormonal therapy, and combinations thereof. One hundred and thirty nine patients received surgical treatment for endometrial cancer: stage I -101 (72,6%), stage II - 9 (6,5%), stage III - 23 (16,6%) and stage IV - 6 (4,3%). Tumors were well differentiated in 87(62,6%), moderately differentiated in 32 (23%) and poorly differentiated in 20 (14,4%). There were 45 (32,4%) premenopausal patients and 94 (67,6%) postmenopausal. In multivariate statistical analysis we identified FIGO stage, tumor type, tumor grade, nodal status and depth of myometrial invasion as independent prognostic factors for overall survival, and FIGO stage, nodal status, and tumor grade as independent prognostic factors for recurrence-free interval.

Published: February 2011

AbstractThis communication presents and justifies ideas related to motion control of snake robots that are currently the subject of ongoing investigations by the authors. In particular, we highlight requirements for intelligent and effcient snake robot locomotion in unstructured environments, and subsequently we present two new design concepts for snake robots that comply with these requirements. The first design concept is an approach for sensing environment contact forces, which is based on measuring the joint constraint forces at the connection between the links of the snake robot. The second design concept involves allowing the cylindrical surface of each link of a snake robot to rotate by a motor inside the link in order to induce propulsive forces on the robot from its environments. The paper details the advantages of the proposed design concepts over previous snake robot designs.

Physiological and Biochemical Effect of Pyriproxyfen on Indian Meal MothPlodia Interpunctella(Hübner) (Lepidoptera: Pyralidae)Insect growth regulators generally have a selective effect on the target insects and have practically no apparent side effect on non-target organisms especially vertebrates. Hence, insect growth regulators could be a suitable choice to control pests in stored products. Ten-day-old larvae of Indian meal mothPlodia interpunctella(Hübner) were expressed to the juvenile hormone analogue pyriproxyfen in order to have an effect on growth, metamorphosis, reproduction, lipid and protein contents of ovaries. The larvae were treated by 0.02, 0.04, 0.08, 0.16, and 0.3 ppm of JHA in an artificial diet where controls received acetone alone. The results indicated significant differences in duration of growth, mean longevity of hatched adults, percentage of emerged normal adults, abnormal pupae, hatched larvae and mean oviposition ratein addition to the lipid and protein of ovaries compared to the controls. An inhibition concentration of fifty (IF50) for prevention of emerging adults was recorded 0.134 ppm. Pyriproxyfen caused significant defects in the legs and wings of some adults and sever morphological changes in the ovaries of emerged adults. The results showed that pyriproxyfen may be applied as an insecticide to decrease the damage caused by Indian meal moth on stored products. Pyriproxyfen can be used with low side effects to humans.

Comparison of Disease Occurrence and Green Leaf Area (GLA) of Winter Wheat Depending on the Forecrop and Differentiated Fungicidal Protection UsedThe effect of the forecrop and differentiated chemical plant protection on the intensity of fungal leaf diseases of winter wheat were studied from 1999-2008. Five (I-V) separate experiments were conducted in Mazury (Szestno I,), Żuławy Wiślane (Lisewo II), and Powiśle (Wielgłowy III, IV and Radostowo V). The intensity of diseases varied. Powdery mildew (Blumeria graminis) was noted in relatively low or trace intensity. On the other hand, there was a large amount of necrotic leaf spot complexes caused byMycosphaerella graminicola, Stagonospora nodorum, Pyrenophora tritici-repentisandFusariumspp. In 2000, 2001 and 2003 brown rust (Puccinia recondita) was noted in high intensity. The applied treatments were very effective in reducing fungal disease on leaves. The surface of the upper leaves (Green leaf area - GLA) with no symptoms of infection and fungicide use were significantly higher than in the control. It was also found that the GLA of crops grown after oilseed rape was higher than the GLA of crops grown after wheat.

Studies on Cereal Soil-Borne Viruses in PolandFour soil-borne cereal viruses have been identified in Poland, so far:Soil-borne cereal mosaic virus(SBCMV),Wheat spindle streak mosaic virus(WSSMV),Barley yellow mosaic virus(BaYMV) andBarley mild mosaic virus(BaMMV). SBCMV was identified in 1993 as a dangerous pathogen of winter cereals and became the object of special interest. Studies on the virus included its biological and molecular characterization, and investigations of the response of winter wheat and winter triticale cultivars on the SBCMV infection. Results of preliminary experiments aiming at the evaluation of the response of winter barley cultivars on barley yellow mosaic viruses were also presented.

An Optimized Tooth Zone for the Low-Speed Double-Fed Induction Generator
The authors present the results of tooth zone optimization for a double-fed induction generator able to operate at a low speed. The generator has a large number of pole pairs, all the windings are placed on the stator, with a winding-less toothed rotor. The optimization concerns the geometry of the tooth zone and is achieved by making the pole extension of trapezoidal shape instead of circular, which allows a 4% increase in the generated power.
