Pediatric Case Reports: Assessing Recommendations From Journals’ Instructions to Authors
Authors: Nguyen Jimmy T. , Shahid Ramzan , Manera Ricarchito 
Published: January 2014

Background:
Case reports (CRs) can be valuable contributions to medical knowledge and education. Objective assessments of publication potential and content recommendations for pediatric CRs are lacking.

Methods:
The “Instructions to Authors” provided by pediatric journals were assessed to determine journal characteristics, manuscript restrictions, and advice to writers. Pediatric journals referenced in the National Center for Biotechnology Information databases were identified by using the search term “pediatric.” Further inclusion criteria were: active journals; currently indexed in the PubMed, Ovid, and/or Medline databases; and English as the primary language.

Results:
Sixty-nine (52%) of 132 pediatric journals surveyed published CRs per their author instructions. The median 2011 impact factor for accepting journals was 1.28 (range: 0.47–5.44) compared with 2.40 (range: 0.59–5.50) for journals that did not publish CRs (P &lt; .001). Twelve (67%) of 18 pediatric surgical specialty journals, 16 (55%) of 29 general pediatric journals, and 38 (51%) of 74 nonsurgical pediatric subspecialty journals published CRs. Sixteen journals had a separate Images section. Twenty-five (36%) of 69 journals provided no recommendations. Of the 44 journals that did provide recommendations, new insights/observations (64%) was the most common content recommendation, followed by clinical relevance (41%), novelty/rarity (39%), and instructive/educational value (32%).

Conclusions:
Approximately one-half of pediatric journals surveyed published CRs per their author instructions. Journals with lower impact factors were more likely to publish CRs. Many journals had specific formatting criteria. New insights and observations regarding relatively known pathology was the content criteria most often recommended.

Published: January 2014

AbstractIn this work is discussed the synthesis of a novel antishrinking agent (SOC DA) and the evaluation of its performance in an acrylic dental resin. SOC DA was photopolymerized in conjunction with the components of a conventional acrylic resin, which includes a mixture of diacrylate monomers [glycerolate bisphenol A dimethacrylate (BIS-GMA) / Urethane dimethacrylate (UDMA) / triethyleneglycol dimethacrylate (TEGDMA)] in 50/30/20 molar ratio). SOC DA was added in a range between 5.0-20.0 mol % with respect to the total amount of moles of the acrylic monomers. It was found that increasing concentrations of SOC DA, promoted higher conversions of the dimethacrylate monomers without decreasing the photopolymerization rate of the acrylate monomers. The study of the effect of SOC DA on the mechanical properties of the dental composite filled with 70 % of silicon dioxide, revealed that the presence of the antishrinking agent improved both the compressive and the flexural strength of the dental materials. Besides, it was found that by using the SOC DA at 20%, the shrinkage was reduced 52%, compared with the same formulation without SOC DA.

ABSTRACTPoly(methyl methacrylate)/biphasic calcium phosphate (PMMA/BCP) coating has been prepared by mixing BCP in situ with the poly(methyl methacrylate) obtained from methyl methacrylate (MMA) polymerization. For comparative studies, concentration of BCP into PMMA matrix was varied in order to determine the influence of BCP incorporation into PMMA matrix on the hardness and friction behavior. The micro-hardness of PMMA/BCP coatings on stainless steel was evaluated using a Vickers hardness tester, while the wear tests for PMMA/BCP coatings on stainless steel were carried out on a CSM tribometer in dry conditions with normal load of 2 N. The incorporation of BCP into the polymer matrix significantly improves the microhardness of PMMA increasing to 15 % with 0.25 wt.% of BCP content. Whereas, the lowest friction coefficient value µk = 0.35 was obtained for PMAA/BCP with 0.35wt.% of BCP.
Morphology and Development of Immature Stage ofDiadromus collaris(Hymenoptera: Ichneumonidae), an Important Endoparasitoid ofPlutella xylostella(Lepidoptera: Plutellidae)
Authors: Zhao Wei , Dong Shuai , Shi Min , Chen Xue-Xin 
Published: January 2014

AbstractDiadromus collaris (Gravenhorst) is an important pupal parasitoid of the diamondback moth, Plutella xylostella (L.), a major insect pest of cruciferous vegetables worldwide. We studied the development of immature stage of D. collaris by dissecting parasitized hosts in the laboratory at 25 ± 1°C and 50–80% relative humidity. The results show that all immature stages complete their development within the same host in 11≈12 d. The egg is hymenopteriform and appears to be anhydropic. There are four larval instars. The first instar is transparent with a sclerotized rectangular chitinous head capsule and distinct mandibles. Head capsule of the second instar turns into more isosceles trapeziumshaped. The third instar looks similar to the second instar but proportionally much larger. The sclerization and dimension of the fourth instar increases significantly. The pupa is a typical exarate form and lacks a cocoon. All life history was fully documented with detailed photomicrographs. Our study will be useful for understanding the physiological interactions between D. collaris and P. xylostella.

AbstractDendroctonus frontalis Zimmermann is considered one of the most important economic and ecological forest pests in the United States, Mexico, and Central America. Recently, two apparent morphological variants of this species were discovered occurring syntopically in Central America and southern Mexico. Morphotype A beetles lack a series of fine parallel ridges on the episternal area of the prothorax that are present on morphotype B. The goal of the present work was to clarify the taxonomic status of the morphotypes of the D. frontalis species complex. Geometric morphometric analyses of seminal rod and spermatheca shape together with the characterization of 16 attributes of external morphology revealed differences in quantitative and qualitative characters that distinguished adults of the two morphotypes from each other as well as from the closely related species Dendroctonus vitei Wood and Dendroctonus mexicanus Hopkins. Karyotype analysis of morphotype B revealed a chromosomal formula (5AA + Xyp) distinct from that found in morphotype A previously reported for D. frontalis (7AA + Xyp). In the laboratory, forced intermorphotype crosses produced F1 progeny but at lower frequency than intramorphotype pairings, and dissections of spermatheca revealed a lower frequency of insemination at least one type of heterotypic cross. Phylogenetic analysis of the D. frontalis species complex based on 786 bp of the cytochrome oxidase I gene indicated that morphotypes B and A are two independent groups with 98% nodal support within D. frontalis. These data provide compelling evidence that the two syntopic morphotypes represent two distinct sibling species.
Localization of ‘Candidatus Liberibacter solanacearum' (Rhizobiales: Rhizobiaceae) in Bactericera cockerelli (Hemiptera: Triozidae)
Authors: Cooper W Rodney , Sengoda Venkatesan G , Munyaneza Joseph E 
Published: January 2014

Abstract
‘Candidatus Liberibacter solanacearum’ is a pathogen of solanaceous crops (Solanales: Solanaceae) that causes zebra chip disease of potato (Solanum tuberosum L.) and plant dieback in tomato (S. lycopersicum L.) and pepper (Capsicum spp.). This pathogen is vectored by the potato/ tomato psyllid Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), but little is known about the interactions between B. cockerelli and ‘Ca. Liberibacter solanacearum.’ Fluorescence in situ hybridization was used to assess the incidence of ‘Ca. Liberibacter solanacearum’ in the hemolymph, bacteriomes, alimentary canals, and salivary glands of B. cockerelli. Liberibacter was observed in 66% of alimentary canals, 39% of salivary glands, and 40% of bacteriomes dissected from adult psyllids. Compared with adults, the organs of fifth instars appeared less likely to harbor Liberibacter, which was observed in 52% of alimentary canals, 10% of salivary glands, and 6% of bacteriomes dissected from the nymphs. Results of real-time polymerase chain reaction confirmed that fewer fifth instars were infected with Liberibacter compared with adults and indicated that fifth instars were less likely to transmit the pathogen to noninfected host plants. These observations of the localization of ‘Ca. Liberibacter solanacearum’ in the organs and tissues of B. cockerelli adults and nymphs will aid the study of Liberibacter-psyllid interactions and the epidemiology of ‘Ca. Liberibacter solanacearum.’

Published: January 2014

Abstract
Armored scale insects include invasive economic pests that have been widely studied in human-altered habitats but have received less attention in natural habitats. Although armored scale insects are nearly ubiquitous associates of woody plants, they generally go uncollected in general surveys because they are not susceptible to mass collecting techniques, such as fogging, beating, or trapping. San Lorenzo National Park in Panama was the subject of a recent high-profile effort to quantify the arthropod diversity in a tropical forest (Basset et al. 2012). Here, we contribute to understanding the biodiversity of this classic site by reporting the armored scale insect species we found there in August 2010. We found that, unlike other rainforest canopy taxa, the armored scale insect fauna is dominated by highly polyphagous cosmopolitan pests. However, we also found new species, and we describe two of them here: Furcaspis douglorum Okusu & Normark n. sp. and Hemiberlesia andradae Okusu & Normark n. sp. We provide amendments to the relevant keys, including a new key to New World species of Hemiberlesia Cockerell that lack perivulvar pores. In this context, we treat Abgrallaspis Balachowsky as asubjective synonym of Hemiberlesia, and we transfer its species to Hemiberlesia, except for the following assignments to other genera Affirmaspis flavida (De Lotto), n. comb., Aspidiotus furcillae Brain, rev. comb., Clavaspis perseae (Davidson), n. comb., Diaspidiotus fraxini (McKenzie), n. comb., and Davidsonaspis aguacatae (Evans, Watson, and Miller), n. comb. Davidsonaspis Normark, n. gen. We regard Abgrallaspis azadirachti Ojha and A narainus Dutta & Singh as synonyms of Aonidiella orientalis (Newstead), new synonymy.

SUMMARY
The purpose of this article is to reflect on the ongoing transformation of the Big 8/6/5/4 public accounting firms, with the intent of helping primarily doctoral students and junior faculty engaged in developing their own research programs. Drawing on a variety of theoretical research traditions that we have employed in our field research spanning over 30 years, we will briefly reconsider three “moments” through which the phenomenon of the multi-discipline (or, as termed in the sociology of professions literature, the “entrepreneurial”) professional service firm has shaped both accounting firms and accountants: Moment I, in which administrative partners implemented centrally orchestrated control systems to better direct the actions of audit team members, and the response of the latter to resist, deflect, and transform such efforts; Moment II, in which the profession attempted to rebrand itself as a professional service delivery system that could offer “higher platforms of service” to a global business community, in a legal and political context shaped by regulators, U.S. presidential and congressional politicians, the lay membership of the American Institute of Certified Public Accountants (AICPA), and such laws as the Sarbanes-Oxley Act; and Moment III, in which the concept of professional entrepreneurialism became internalized within and acted upon by both individual professionals and firms, although in a manner not wholly controlled by administrative partners nor practice partners. Impressions gleaned from this reflective exercise are explored, and implications for researchers who may be contemplating field research using qualitative methods are sketched.

Published: January 2014

OBJECTIVE
It has been hypothesized that the development of diabetic polyneuropathy (DPN) is due to swelling of the nerve, as well as thickening and stiffening of the surrounding ligaments, causing chronic compression of nerves. We aimed to examine the effect of surgical decompression of the tibial nerve on the mean cross-sectional area (CSA).

RESEARCH DESIGN AND METHODS
We performed a randomized controlled trial of 42 subjects with painful DPN diagnosed using the Diabetic Neuropathy Score. A computer randomized for the surgery arm of the study. A control group consisting of 38 healthy subjects was included. An experienced sonographer measured the CSA and thickness-to-width (T/W) ratio of the tibial nerve, as well as the thickness of the flexor retinaculum.

RESULTS
CSA is significantly larger in patients with painful DPN (8.4 ± 3.9 mm2) than in control subjects (6.4 ± 1.3 mm2), P = 0.007. The T/W ratio in patients with painful DPN is 0.64 and in control subjects 0.59, P = 0.03. Patients with DPN have a significantly thicker retinaculum (1.07 mm) than control subjects (0.84 mm), P &lt; 0.001. Mean follow-up was 28.2 weeks (range 23–45). Difference between baseline and follow-up in the operated leg was 1.49 mm2 and in the control leg 1.81 mm2, P = 0.674.

CONCLUSIONS
Decompression of the tibial nerve does not result in a significant difference between baseline and follow-up in CSA using ultrasound between the operated and control leg. Ultrasound measurements show a significantly increased CSA, a significantly thicker retinaculum, and a significantly increased T/W ratio in patients with painful DPN compared with healthy control subjects.

Published: January 2014

Abstract Metabolic syndrome (MetS) is a chronic, multi-component disease characterised by central obesity, hyperglycaemia, dyslipidaemia, and hypertension. Since MetS leads to type 2 diabetes, cardiovascular disease, development of certain cancers, and eventually to premature death, it is not surprising that it draws the attention of scientists around the world. The aetiopathology of MetS is complex and still not fully understood. This review focuses on the role of endocrine factors such as cortisol and insulin in the development of MetS. It also takes a look at some of the contributing lifestyle and genetic factors as well as at the current knowledge about its treatment.

Published: January 2014

Abstract This multicentre, cross-sectional observational study aimed to determine the prevalence of depression among the working population of Slovenia and identify factors correlating with higher prevalence of depression. It was conducted in three occupational medicine practices within major Slovenian primary health care centres. The study population consisted of 1,474 respondents [73.7 % of the invited participants, 889 (60.3 %) men and 585 (39.7 %) women with mean age of (40.5±9.8) years] who visited these practices for their regular check-ups from November 2010 to June 2012 and were asked to fill in a self-developed questionnaire and score depression on the Zung’s self-rating depression scale. According to the rating, 50 (3.4 %) respondents suffered from depression. In the multivariate analysis, depression correlated with the following independent variables: self-perceived exposure to chronic stress, positive family history of depression, and primary school education.

Polityka zrównoważonego rozwoju, wzrost świadomości społeczeństw oraz wynikające stąd ambitne cele w zakresie polityki energetycznej w Unii Europejskiej z jednej strony zmuszają, a z drugiej inspirują przed- siębiorstwa do poprawiania sprawności energetycznej stosowanych technologii. Przemysł koksowniczy w Polsce i całej Europie także poszukuje dróg optymalnego rozwoju technologicznego, pozwalającego na poprawę efek- tywności energetycznej, a przez to także zwiększenia rentowności przedsiębiorstwa. Koksownictwo krajowe poszukuje również technologii pozwalających w jeszcze większym stopniu na korzystanie z krajowych zasobów węgli, a przez to z renty geograficznej (Ozga-Blaschke 2012; Kasztelewicz 2012). Jednym z bardziej atrakcyjnych kierunków rozwoju dla polskich koksowni, spełniającym łącznie wszystkie te postulaty, jest wdrożenie operacji podsuszania wsadu. Skojarzenie tej technologii z instalacją suchego chłodzenia koksu sprawia, że obie te technologie stosowane łącznie znacznie podnoszą sprawność energetyczną procesu koksowania, a jednostkowe zużycie gazu koksowniczego może spaść o 12,6%. W artykule przeprowadzono analizę wyników w zakresie poprawy efektywności energetycznej procesu koksowania po wdrożeniu operacji podsuszania wsadu niezależnie oraz w skojarzeniu z instalacją suchego chłodzenia koksu. W pierwszym rozważanym przypadku możliwe jest ograniczenie zużycia ciepła koksowania o 2,8%. Natomiast skojarzenie tych dwóch technologii, poza innymi pozytywnymi efektami, znacząco zwiększa skalę oszczędności do 12,6%. Całkowite ciepło potrzebne dla skok- sowania wsadu wynoszące 2600 MJ/t wsadu wilgotnego, zmniejsza się do 2527,5 MJ/t wsadu wilgotnego w przypadku wdrożenia operacji podsuszania samoistnie, a w przypadku skojarzenia tej instalacji z technologią suchego chłodzenia koksu do 2273,6 MJ/t wsadu wilgotnego. Skojarzenie obu tych technologii zdaje się być szczególnie atrakcyjne w aspekcie energetycznym ponieważ pozwala wykorzystać entalpię fizyczną gorącego koksu z bardzo wysoką sprawnością. W końcowej części przedstawiono porównanie podstawowych parametrów energetycznych procesu koksowania dla różnych układów technologicznych, obejmujących podsuszanie wsadu i/lub suche chłodzenie koksu.

Największe szanse na udokumentowanie zasobów perspektywicznych złóż rud Zn-Pb w Polsce występują w obszarze o powierzchni około 2000 km2 usytuowanym na północ od udokumentowanych złóż siarczkowych Zn-Pb regionu zawierciańskiego. Wydzielone zostały tam cztery rejony perspektywiczne dla wystąpień złóż rud siarczkowych Zn-Pb typu Mississippi Valery Type (MVT) w utworach węglanowych triasu (wapień muszlowy) i dewonu. Za najbardziej obiecujący uznano obszar na NW od Myszkowa oraz obszar na SE od Koziegłowów. Jednak ze względu na słabe rozpoznanie wiertnicze zasoby md Zn-Pb są trudne do oszacowania. Celowe jest przeprowadzenie dalszych prac geofizycznych (np. metodą 1P), które w przypadku pozytywnych wyników należałoby rozpoznać wierceniami. W cechsztyńskiej formacji miedzionośnej na monoklinie przedsudeckiej (wokół obszaru złożowego Lubin- -Sieroszowice), na peryklinie Żar (na SW od Zielonej Góry) i w niecce północnosudeckiej (wokół złóż Konrad i Lena-Nowy Kościół oraz na N od Zgorzelca) znanych jest kilka obszarów występowania bogatej mineralizacji Pb-Zn. Jednak ze względu na dużą głębokość zalegania mineralizacji, okruszcowanie to może stanowić jedynie kopalinę towarzyszącą wydobywaną przy okazji eksploatacji rud Cu-Ag. Jednak pomimo znacznych zasobów cynk jak dotychczas nie jest odzyskiwany w procesach przeróbczych jak i metalurgicznych przez KGHM Polska Miedź S.A. Liczne drobne wystąpienia mineralizacji Zn-Pb i Pb w Sudetach, G. Świętokrzyskich oraz w strefie kontaktu bloku małopolskiego z górnośląskim nie mają znaczenia ekonomicznego jednak stanowią ważne przesłanki dla dalszych poszukiwań, które mogą doprowadzić do odkrycia złóż siarczkowych Zn i/lub Pb, różnorodnych pod względem genetycznym (stratoidalne, hydrotermalne żyłowe i/lub brekcje, kontaktowo-metasomatyczne, SEDEX) jak i zasobowym.

Streszczenie
Artykuł przedstawia przydatność metody flotacyjnej w przeróbce kopaliny talkowej pochodzącej ze złoża Gemerska Polonia. Wnioski oparte są na analizie wyników badań kontrolowanych próbek materiału z prób produkcyjnych, które zostały przeprowadzone w dwóch instalacjach flotacyjnych. Ocena wyników tych prób przemysłowych, w tym analizy chemicznej i innych analiz jakościowych przeprowadzonych na próbkach kon- trolnych, potwierdzają stosunkowo wysoki poziom białości - w zakresie od 83,9-88,0% - w otrzymanych koncentratach talku. Wiadomo jednak, że surowiec talkowy osiągnie swój ostateczny poziom białości po jego zmieleniu do docelowej granulacji. Badania potwierdzają również wysoką skuteczność separacji pirytu i innych minerałów towarzyszących w trakcie flotacji. Na podstawie wyników analizy chemicznej koncentratów talku, uzasadnione jest stwierdzenie, że metoda flotacji może być uznana za odpowiednią metodę wzbogacania kopaliny talkowej pochodzącej ze złoża Gemerska Polonia. Złoże talku Gemerska Polonia zostało udokumentowane pod koniec lat dziewięćdziesiątych XX wieku. W 1988 roku podczas badań geologicznych w rejonie Gemerska Polonia na końcu doliny Dlha, w wyniku przeprowadzonych prac wiertniczych (3 otwory) stwierdzono mineralizację talkowo-magnezytową. Unikalne złoże talku może mieć duże znaczenie na rynku europejskim, będąc porównywalnym do największych światowych złóż tej kopaliny. Eksperci uważają złoże talku Gemerska Polonia pod względem wymiarów, jakości kopaliny i ilości zasobów, jako jedno z największych na świecie. Jego kluczową zaletą jest dobre strategiczne położenie w centrum Europy. Oceny ekonomiczne tego złoża dają perspektywę długoletniej zyskownej działalności pro- dukcyjnej, a działalność ta może także częściowo ożywić górniczo-geologiczny rynek pracy w tym regionie. Popyt na ten surowiec w Europie ma stałą tendencję wzrostową.
