Germinación y emergencia de cuatro híbridos de girasol ("helianthus annuus" L.) con diferente contenido lipídico y en relación con la temperatura

Se realizo un analisis comparativo de la germinacion y la emergencia de cuatro hibridos de girasol (Helianthus annuus L.) en funcion de la temperatura y de su contenido de acido oleico y linoleico de las semillas. Los experimentos se desarrollaron en condiciones de laboratorio y de campo. En el laboratorio se utilizo un sistema de germinacion de gradiente termico con un rango de temperatura comprendico entre 2 y 40o C. El analisis cuantitativo se realizo a partir del porcentaje de la germinacion acumulada determinado para cada hibrido en funcion del tiempo, utilizando un modelo de ajuste no lineal. Los parametros del modelo fueron comparados estadisticamente entre los distintos hibridos. En el campo se hicieron siembras en microparcelas durante los meses invernales de julio y agosto. La temperatura del suelo a la profundidad de siembra se registro en forma continua y se evaluaron los periodos transcurridos entre siembra, germinacion y emergencia de las plantulas. En todos los casos los experimentos se repitieron una vez. Se observaron diferencias de la dinamica de la germinacion acumulada entre los hibridos estudiados a temperaturas constantes, asi como en el comportamiento de los mismos en las siembras realizadas en el campo. Los hibridos que presentaron un mayor ritmo de germinacion a temperaturas menores de 15o C en el gradiente termico tuvieron un adelanto de entre tres y cinco dias en la emergencia en condiciones de campo. Se observo una relacion inversa entre el cociente contenido de acido linoleico/contenido de acido oleico y la capacidad de las semillas para germinar en un rango de temperatura inferior a 10o C. El contenido de estos acidos grasos podria incorporarse a los criterios de seleccion tendentes a obtener un mejor comportamiento de la germinacion y emergencia de diferentes genotipos frente a condiciones termicas desfavorables.
Nucleotide sequence analysis establishes the role of endogenous murine leukemia virus DNA segments in formation of recombinant mink cell focus-forming murine leukemia viruses

The sequence of 363 nucleotides near the 3' end of the pol gene and 564 nucleotides from the 5' terminus of the env gene in an endogenous murine leukemia viral (MuLV) DNA segment, cloned from AKR/J mouse DNA and designated as A-12, was obtained. For comparison, the nucleotide sequence in an analogous portion of AKR mink cell focus-forming (MCF) 247 MuLV provirus was also determined. Sequence features unique to MCF247 MuLV DNA in the 3' pol and 5' env regions were identified by comparison with nucleotide sequences in analogous regions of NFS -Th-1 xenotropic and AKR ecotropic MuLV proviruses. These included (i) an insertion of 12 base pairs encoding four amino acids located 60 base pairs from the 3' terminus of the pol gene and immediately preceding the env gene, (ii) the deletion of 12 base pairs (encoding four amino acids) and the insertion of 3 base pairs (encoding one amino acid) in the 5' portion of the env gene, and (iii) single base substitutions resulting in 2 MCF247 -specific amino acids in the 3' pol and 23 in the 5' env regions. Nucleotide sequence comparison involving the 3' pol and 5' env regions of AKR MCF247 , NFS xenotropic, and AKR ecotropic MuLV proviruses with the cloned endogenous MuLV DNA indicated that MCF247 proviral DNA sequences were conserved in the cloned endogenous MuLV proviral segment. In fact, total nucleotide sequence identity existed between the endogenous MuLV DNA and the MCF247 MuLV provirus in the 3' portion of the pol gene. In the 5' env region, only 4 of 564 nucleotides were different, resulting in three amino acid changes between AKR MCF247 MuLV DNA and the endogenous MuLV DNA present in clone A-12. In addition, nucleotide sequence comparison indicated that Moloney-and Friend-MCF MuLVs were also highly related in the 3' pol and 5' env regions to the cloned endogenous MuLV DNA. These results establish the role of endogenous MuLV DNA segments in generation of recombinant MCF viruses.
Field Plate Design for Low Leakage Current in Lateral GaN Power Schottky Diodes: Role of the Pinch-off Voltage

In this letter, we demonstrate a general model to reduce the reverse leakage current (<inline-formula> <tex-math notation="LaTeX">${I}_{\text {R}}$ </tex-math></inline-formula>) in high-voltage AlGaN/GaN Schottky diodes (SBDs) by engineering the pinchoff voltage (<inline-formula> <tex-math notation="LaTeX">${V}_{\text {p}}$ </tex-math></inline-formula>) of their field plates (FPs). The maximum voltage drop at the Schottky junction (<inline-formula> <tex-math notation="LaTeX">${V}_{\text {SCH}}$ </tex-math></inline-formula>) in the OFF state can be significantly decreased by reducing <inline-formula> <tex-math notation="LaTeX">$\vert {V}_{p}\vert $ </tex-math></inline-formula>, which leads to a drastically diminished <inline-formula> <tex-math notation="LaTeX">${I}_{\text {R}}$ </tex-math></inline-formula>. We used a tri-gate architecture as means to control <inline-formula> <tex-math notation="LaTeX">${V}_{\text {p}}$ </tex-math></inline-formula> and, thus, <inline-formula> <tex-math notation="LaTeX">${I}_{\text {R}}$ </tex-math></inline-formula>, as it offers great flexibility to engineer <inline-formula> <tex-math notation="LaTeX">${V}_{\text {p}}$ </tex-math></inline-formula> compared with conventional schemes. <inline-formula> <tex-math notation="LaTeX">$\vert {V}_{\text {p}}\vert $ </tex-math></inline-formula> of SBDs with tri-gate FPs was reduced by decreasing the width of the nanowires, which led to a very small <inline-formula> <tex-math notation="LaTeX">${I}_{\text {R}}$ </tex-math></inline-formula>, below 10 nA/mm under reverse biases up to 500 V, and an increase of over 800 V in soft breakdown voltage (<inline-formula> <tex-math notation="LaTeX">${V}_{\text {BR}}$ </tex-math></inline-formula>) at <inline-formula> <tex-math notation="LaTeX">$1~\mu \text{A}$ </tex-math></inline-formula>/mm. These results reveal the importance of <inline-formula> <tex-math notation="LaTeX">${V}_{\text {p}}$ </tex-math></inline-formula> in reducing <inline-formula> <tex-math notation="LaTeX">${I}_{\text {R}}$ </tex-math></inline-formula> for SBDs, and unveil the potential of tri-gate structures as FPs for power devices.
Surgery for cervical intraepithelial neoplasia.

BACKGROUND Cervical intraepithelial neoplasia (CIN) is the most common pre-malignant lesion. Atypical squamous changes occur in the transformation zone of the cervix with mild, moderate or severe changes described by their depth (CIN 1, 2 or 3). Cervical intraepithelial neoplasia is treated by local ablation or lower morbidity excision techniques. Choice of treatment depends on the grade and extent of the disease. OBJECTIVES To assess the effectiveness and safety of alternative surgical treatments for CIN. SEARCH METHODS We searched the Cochrane Gynaecological Cancer Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (up to November 2012). We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. SELECTION CRITERIA Randomised controlled trials (RCTs) of alternative surgical treatments in women with cervical intraepithelial neoplasia. DATA COLLECTION AND ANALYSIS Two review authors independently abstracted data and assessed risks of bias. Risk ratios that compared residual disease after the follow-up examination and adverse events in women who received one of either laser ablation, laser conisation, large loop excision of the transformation zone (LLETZ), knife conisation or cryotherapy were pooled in random-effects model meta-analyses. MAIN RESULTS Twenty-nine trials were included. Seven surgical techniques were tested in various comparisons. No significant differences in treatment failures were demonstrated in terms of persistent disease after treatment. Large loop excision of the transformation zone appeared to provide the most reliable specimens for histology with the least morbidity. Morbidity was lower than with laser conisation, although the trials did not provide data for every outcome measure. There were not enough data to assess the effect on morbidity when compared with laser ablation. AUTHORS' CONCLUSIONS The evidence suggests that there is no obvious superior surgical technique for treating cervical intraepithelial neoplasia in terms of treatment failures or operative morbidity.
Specialization and habitat: spatial and environmental effects on abundance and genetic diversity of forest generalist and specialist Carabus species

Habitat specialist species are supposed to be more susceptible to variations in local environmental characteristics than generalists. To test this hypothesis, we conducted a comparative analysis on abundance and genetic diversity of forest carabids differing in their habitat requirements. Four species were sampled in forests characterized by abiotic, landscape and biotic environmental variables. A statistical framework based on canonical correspondence analysis was used for one habitat generalist and one habitat specialist species to determine the relative contribution of environmental variables in structuring inter‐ and intrapopulational genetic diversity depicted by microsatellites. Our results showed that sympatric species differed in their sensitivity to environmental variables. The same variables were found to be important in analyses of abundance and genetic data. However, specialization was not related to a greater sensitivity to local environmental characteristics. The strong impact of spatial variables on genetic data suggested that genetic variation among populations would largely reflect the response of individual species to dispersal opportunities more than the effect of habitat quality.

Preparation of Silver Nanoparticles in Cellulose Acetate Polymer and the Reaction Chemistry of Silver Complexes in the Polymer

Copper complexes have been directly incorporated into cellulose acetate (CA) and the resulting light blue colored homogeneous films of 5-20 wt. % copper acetate complex concentrations are found to be thermally stable up to200 °C. The reaction chemistry of Cu in CA has been investigated by reacting them with small gas molecules such as CO, H 2 , D 2 , O 2 , NO, and olefins in the temperature range of 25-160 °C, and various Cu-hydride, -carbonyl, -nitrosyl, and olefin species coordinated to Cu sites in CA are characterized by IR and UV/ Vis spectroscopic study. The reduction of Cu(II) complexes by reacting with H 2 gas at the described conditions results in the formation of Cu 2 O and copper metal nanoparticles in CA, and their sizes in 30-120 nm range are found to be controlled by adjusting metal complex concentration in CA and/or the reduction reaction conditions. These small copper metal particles show various catalytic reactivity in hydrogenation of olefins and CH 3 CN; CO oxidation; and NO reduction reactions under relatively mild conditions.
Red Bone Marrow and Male Breast Doses for a Cohort of Atomic Veterans

Both red bone marrow and male breast doses with associated uncertainty have been reconstructed for a 1,982-person subset of a cohort of 114, 270 military personnel (referred to as “atomic veterans”) who participated in U.S. atmospheric nuclear weapons testing from 1945 to 1962. The methods used to calculate these doses and corresponding uncertainty have been reported in detail by Till et al. in an earlier publication. In this current article we report the final results of those calculations. These doses are being used in a case-cohort design epidemiological investigation of leukemia and male breast cancer. This cohort of atomic veterans is one component in a broader-scope study of approximately one million U.S. persons designed to investigate risk from chronic low-dose radiation exposure. Doses to the atomic veterans in this sub-cohort were relatively low, with approximately two-thirds receiving red bone marrow doses <5 mGy and only four individuals receiving a red bone marrow dose >50 mGy. The average red bone marrow dose for members of the sub-cohort was 5.9 mGy. Doses to male breast were approximately 20% higher than red bone marrow doses. The uncertainty in the estimated doses was relatively low, considering relevant personnel dosimetry was available for only about 25% of the subjects, and most of the doses were reconstructed from film badges worn by co-workers or from the individual's military record and military unit activities. The average coefficient of variation for the individual dose estimates was approximately 0.5, comparable to the uncertainty in doses estimated for the Japanese A-bomb survivors. Although the reconstructed red bone marrow doses were about 36% lower on average than the conservative doses previously estimated by the military for compensation, the overall correlation was quite good, suggesting that the estimates of doses from external exposure by the military for all ∼115,000 cohort members could be adjusted appropriately and used in further epidemiological analyses.
Recent Advances and Future Prospects of Phthalimide Derivatives

Article history: Received on: 21/05/2015 Revised on: 13/09/2015 Accepted on: 02/11/2015 Available online: 10/03/2016 Among bicyclic non-aromatic nitrogen heterocycles, phthalimides are an interesting class of compounds with a large range of applications. Phthalimide contains an imide functional group and may be considered as nitrogen analogues of anhydrides or as diacyl derivatives of ammonia. They are lipophilic and neutral compounds and can therefore easily cross biological membranes in vivo and showing different pharmacological activities. In the present work compounds containing phthalimide subunit have been described as a scaffold to design new prototypes drug candidates with different biological activities and are used in different diseases as, for example AIDS, tumor, diabetes, multiple myeloma, convulsion, inflammation, pain, bacterial infection among others.
The biological properties of human insulin. Subcutaneous absorption, receptor binding and the clinical effect in diabetics assessed by a new statistical method.

Semisynthetic human insulin (Novo) was compared with porcine insulin with regard to absorption from subcutaneous depots, blood glucose control and plasma insulin concentrations in patients, and the binding to insulin receptors of porcine and human origin. The binding affinities of semisynthetic human insulin and porcine insulin were identical with human erythrocyte receptors and receptors on porcine hepatocytes. The subcutaneous absorption of semisynthetic human and porcine 125I-labelled insulin both of soluble and lente type was identical. The metabolic control study was performed as a double-blind crossover study in eight type I diabetics. They received semisynthetic human insulin and porcine insulin (of soluble as well as lente type) for 10 days each, the last 7 days in each period being the observation period. Blood glucose concentration was measured 9 times per 24 hours. No statistically significant differences were found between mean blood glucose levels at the 9 samplings or in the overall mean blood glucose concentration. Further, the blood glucose control was evaluated as a function of time by a computerized method for time series analysis of a complex dynamic system. This method described adequately each blood glucose value as a linear function of the immediately preceding blood glucose value and that measured 24 hours before. No difference was found between human and porcine insulin when the blood glucose control was assessed by this method. Plasma concentrations of total insulin (IRI) and free IRI before and 3 hours after the morning insulin injection were identical in the two treatment periods. It is concluded that human and porcine insulin can be interchanged in the treatment of diabetics without changing the dose.
The Apple Snail Pomacea maculata (Caenogastropoda: Ampullariidae) as the Intermediate Host of Stomylotrema gratiosus (Trematoda: Stomylotrematidae) in Brazil: The First Report of a Mollusc Host of a Stomylotrematid Trematode

Abstract: Trematodes belonging to the family Stomylotrematidae are intestinal parasites of birds. Despite the worldwide distribution and diversity of host species, the first intermediate host remains unknown. For a survey of parasites of Pomacea maculata, snails were collected from the municipality of São Vicente Férrer, state of Maranhão, northeastern Brazil. In the present study, the xiphidiocercariae shed from these snails were used in the experimental infection of the water bug Belostoma plebejum. The insect mortality was observed 30 days post-infection, and the metacercariae recovered in the body cavity of B. plebejum were identified as Stomylotrema gratiosus. This is the first report of an ampullariid snail as intermediate host of stomylotrematid trematodes.
MOBILISING AND MODALISING POETRY IN A SOWETO CLASSROOM

t is true to say that poetry is a defunct genre in most South African English second language classrooms. This was certainly true of the school in which I our case study is situated, Lamula Jubilee High School, Soweto, where the teaching of poetry was dropped in 1996 since it was ‘too difficult’ for students. Outside of the South African context, and even within contexts of English home language instruction, it appears that this condensed, dense and sometimes complex genre has lost its position of prominence in English classrooms, as testified by many writers on English in education. As early as the 1930s, Jenkinson reported the unyielding resistance to poetry and deplored the unsuitable diet of poetry offered at school in the UK (Jenkinson in Andrews 2). Fox and Merrick, reporting on an English teachers’ conference in England in the mid-80s, stated that poetry was ‘rarely popular with pupils’ (332). Richard Andrews’s book published in 1991 was tellingly called The Problem with Poetry. In his recent book on the development of the English novel, the critic Terry Eagleton comments on the declining position of poetry in the public literary space:
Comprehensive Deep Venous Thrombosis Prevention Strategy After Total-Knee Arthroplasty

Ragucci MV, Leali A, Moroz A, Fetto J: Comprehensive deep venous thrombosis prevention strategy after total-knee arthroplasty. Am J Phys Med Rehabil 2003;82:164–168. Objective Venous thromboembolism after total-knee arthroplasty represents a common early postoperative complication resulting in significant morbidity. Despite this, the optimal prophylactic regimen is controversial. The prevalence of venous thromboembolism has been cited as high as 35% in patients receiving pharmacologic prevention alone. We investigated the efficacy of a comprehensive prevention protocol encompassing the use of epidural anesthesia, aspirin, venous foot compression pumps, and early mobilization in a series of consecutive total-knee arthroplasties. Design A series of 100 consecutive total-knee arthroplasty patients were enrolled into the prospective trial. All patients were allowed full weight bearing on the first postoperative day and ambulation as tolerated. Venous foot compression pumps and aspirin were used immediately after surgery in the totality of subjects. Seventy-five percent of the patients were transferred to an acute rehabilitation service during the first postoperative week. The presence of deep-vein thrombosis was subsequently determined with the routine use of venous duplex scans. Results Three patients (3%) demonstrated evidence of distal deep-vein thrombosis. No patient had symptomatic pulmonary embolism. Conclusion The combination of epidural anesthesia, aspirin, immediate postoperative venous foot compression pumps, and early ambulation together seem to be a more effective approach to prevent the occurrence of thromboembolic events after knee replacements than pharmacologic prevention alone.
Simple Tight Upper Bounds for Average SEP and BEP of Coherent Diversity $M$-ary Biorthogonal Signals Over Fading Channels

This paper presents simple tight upper bound expressions for the average symbol error probability and bit error probability of coherent M-ary biorthogonal signals over fading channels with diversity reception. The upper bounds, which do not involve numerical integration and are expressed with only elementary functions, can be efficiently evaluated. In addition, they are valid for different diversity-combining techniques, as well as for arbitrarily correlated and/or nonidentically distributed channels. The tightness of the derived upper bounds is clarified under various channel conditions. Numerical results are also provided to demonstrate the impact of nonidentical channels on the system average error performance.
