Molecular Phylogeny of Sunflower Cultivars of Teddy Bear, Skyscraper, Lemon Queen and Common Sunflower Using RAPD Markers

Helianthus or sunflower is a genus of plant comprising about 70 species. Common sunflower and other members of Helianthae are cultivated in temperate regions and some tropical regions as food crops for humans, cattle, poultry, and as ornamental plants. The common sunflower is valuable with respect of economic and ornamental point of view. There are many cultivars of sunflower including teddy bear, skyscraper, and lemon queen. Variation among these cultivars has been studied using molecular techniques and the result were used to develop the phylogeny among them. Random Amplified Polymorphic DNA (RAPD) is one of molecular techniques that were used for this purpose. The purpose of this study was to contruct the phylogeny of three sunflower cultivars and common sunflower based on RAPD markers. The RAPD primers used in this study were OPA-2, OPA-9, OPA-13, OPB-2, OPB-4, OPB5, OPB-7, and OPB-11. Data analysis based on molecular data showed that genetic relationship among Lemon Queen, Skyscraper, Teddy Bear and Common sunflower based on RAPD markers shows that the cultivars studied are grouped into three main groups, namely: Group I Lemon Queen and Skyscraper, Group II Teddy Bear, and Group III Common sunflower; the closest kinship is shown between Lemon Queen and Skyscraper.
Histone Methylation and Epigenetic Silencing in Breast Cancer

Abstract : This research was to investigate the role of a chromatin-modifying enzyme, called EZH2, in breast cancer epigenetics and to develop strategies to identify chemical inhibitors of this enzyme. EZH2 is a histone methyltransferase which modifies lysine-27 of histone H3, an epigenetic mark linked to gene silencing and implicated in tumor suppressor silencing during breast cancer progression. Progress on this project included: 1) Identification of target genes directly silenced by EZH2 in breast cancer cells, 2) Mapping of EZH2 association within the chromatin of one such target gene, 3) Demonstration that a DNA-binding protein, called YY1, co-localizes at this target chromatin, and 4) Evidence that YY1 is needed for silencing and EZH2 chromatin binding at this target gene. These results suggest that YY1 binding sites help define response elements that recruit and mediate EZH2 silencing in breast cancer cells. The defined EZH2 response element was evaluated for use in developing a breast cancer cell-based bioassay to screen for EZH2 inhibitors. These inhibitors provide important drug compounds to test as part of emerging epigenetic therapies to combat cancer.
Phase I trial of convection-enhanced delivery of nimustine hydrochloride (ACNU) for brainstem recurrent glioma

Abstract Background Treatment options for patients suffering brainstem gliomas are quite limited as surgery is not an option against intrinsic tumors at brainstem and chemotherapy generally failed to demonstrate its efficacy. Intracerebral convection-enhanced delivery (CED) is a novel approach for administering chemotherapy to patients with brain tumors. We present the results of phase I trial of CED of nimustine hydrochloride (ACNU), designed to determine the maximum tolerable concentration of ACNU, for patients with recurrent brainstem gliomas. Methods Sixteen patients, aged 3–81 years old, suffering from recurrent brainstem gliomas, including diffuse intrinsic pontine glioma patients as well as patients with recurrent gliomas that originated from non‐brainstem sites, were enrolled in this trial between February 2011 and April 2016. The dose/concentration escalation trial included 3 dose/concentration groups (0.25, 0.5, and 0.75 mg/mL, all at 7 mL) to determine the safety and tolerability of CED of ACNU. Real-time monitoring of drug distribution was performed by mixing gadolinium-tetraazacyclododecanetetraacetic acid (Gd-DOTA) in the infusion solution. CED of ACNU was given in combination with oral or intravenous temozolomide chemotherapy. Results CED of ACNU demonstrated antitumor activity, as assessed by radiographic changes and prolonged overall survival. The recommended dosage was 0.75 mg/mL. Drug-associated toxicity was minimal. Conclusions Intracerebral CED of ACNU under real-time monitoring of drug distribution, in combination with systemic temozolomide, was well tolerated among patients with recurrent brainstem gliomas. The safety and efficacy observed suggest the clinical benefits of this strategy against this devastating disease. Based on this phase I study, further clinical development of ACNU is warranted.
Diet assessments as a tool to control invasive species: comparison between Monk and Rose-ringed parakeets with stable isotopes

Food is a main limiting factor for most populations. As a consequence, knowledge about the diet of invasive alien species determines the design of control measures. The Monk and Rose-ringed parakeets are two typical species of successful invasive parrots that are highly appreciated by people. Although some observations suggest that Monk parakeets rely on a higher percentage of anthropogenic food than Rose-ringed parakeets, no detailed quantitative data is available. The aim of this study was to compare the diet of the two parakeets using stable isotope analysis (SIA). We performed SIA of carbon and nitrogen in feathers collected in Barcelona, Spain. We also measured isotopic ratios for potential food sources. We reconstructed the diet of parakeets using Bayesian mixing models. The two species differed in the isotopic signatures of their feathers for both δ13C and δ15N. Diet reconstruction showed that Monk parakeets feed mainly on anthropogenic food (41.7%), herbaceous plants (26.9%) and leaves/seeds (22.2%), while Rose-ringed parakeets feed mainly on flowers/fruits (44.1%), anthropogenic food provided in the trap located at the museum (32.4%) and leaves/seeds (23.1%). The more detailed information we can obtain from the diet of these species is useful to develop more effective control measures for their populations. The Monk parakeet may be more susceptible to control through education local residents, given the greater use of anthropogenic food in this species compared to Rose-ringed parakeet. Our conclusions also indicate that SIA is a powerful tool in providing crucial information about the diet and informing measures to control invasive species.
High-intensity focused ultrasound beam path visualization using ultrasound imaging

In High-Intensity Focused Ultrasound (HIFU) treatment, effective localization of HIFU focus is important for developing a safe treatment plan. While Magnetic Resonance Imaging guided HIFU (MRIgHIFU) can visualize the ultrasound path during the treatment for localizing HIFU focus, it is challenging in ultrasound imaging guided HIFU (USIgHIFU). In the present study, a real-time ultrasound beam visualization technique capable of localizing HIFU focus is presented for USIgHIFU. In the proposed method, a short pulse, with the same center frequency of an imaging ultrasound transducer below the regulated acoustic intensity (i.e., Ispta < 720 mW/cm(2)), was transmitted through a HIFU transducer whereupon backscattered signals were received by the imaging transducer. To visualize the HIFU beam path, the backscattered signals underwent dynamic receive focusing and subsequent echo processing. From in vitro experiments with bovine serum albumin gel phantoms, the HIFU beam path was clearly depicted with low acoustic intensity (i.e., Ispta of 94.8 mW/cm(2)) and the HIFU focus was successfully localized before any damages were produced. This result indicates that the proposed ultrasound beam path visualization method can be used for localizing the HIFU focus in real time while minimizing unwanted tissue damage in USIgHIFU treatment.

Technological diffusion dynamics in developed and developing economies: an analysis for the information and communication technologies (ICT)

espanol? Como es la dinamica del proceso de difusion de las TIC en los paises desarrollados y en desarrollo? La investigacion se baso en el modelo Bass (1969) y utilizo los datos de consumo empirico para el G7 y los BRICS. Los principales resultados fueron: i) el modelo ajusto las curvas de difusion con tasas de error bajas [0,2% -5,1%]; ii) no hay relacion directa entre la velocidad y el nivel de desarrollo; iii) los paises desarrollados han alcanzado el punto de infl exion en el proceso de difusion antes que los paises en desarrollo; iv) en algunos paises solo aproximadamente la mitad de la poblacion tendra acceso a internet. En los paises en desarrollo, el proceso para captar nuevos adoptadores es lento, y mientras los paises desarrollados estan alcanzando la saturacion, en la mayoria de los paises en desarrollo estas tecnologias aun tienen potencial para la difusion EnglishHow are the diffusion process dynamics of the ICT in developed and develop-ing countries? The research was based on the Bass model (1969) and used the empirical consumption data for the G7 and BRICS. The main results were: i) the model adjusted the diffusion curves with low error rates [. 2%-5.1%]; ii) no direct relationship between the speed and development level was found; iii) developed countries have reached the infl ection point in the diffusion process before devel-oping countries; iv) in some countries only approximately half of the population will get access to the Internet. In developing countries, the process to capture new adopters is slow, and while developed countries are reaching saturation, in most of the developing countries these technologies still have potential for diffusion.

Calidad del nixtamal y su relación con el ambiente de cultivo del maíz

SUMMARY The nixtamal production in Mexico demands high quality maize (Zea mays L.). To achieve the required quality, it is necessary to know the influence of cropping practices on the biometric properties of the grain. This study evaluated quality characteristics of nixtamal of hybrid maize ‘Puma’ distributed by Monsanto, cultivated during the 2004 Spring-Summer season with five irrigation-fertilization ratios (50-50 %, 50-75%, 75-50 %, 75-75 % y 100-100 %, of 80 cm irrigation and 200 kg of N ha -1 ). The experimental design was a randomized block design with five replications. It was observed that reduction of 25 % in water surface and on the nitrogen applied (75-75 % treatment) significantly increased grain yield and improved the nixtamal making process.
The Shifting Importance of Competition and Facilitation Along Diversity, Environmental Severity, and Plant Ontogenetic Gradients

Encroachment of woody vegetation into grasslands is a widespread phenomenon that alters plant community composition and ecosystem function. Woody encroachment is often the result of fire suppression, but may also be related to changes in resource availability associated with global environmental change. We tested the relative strength of three important global change factors (CO2 enrichment, nitrogen deposition, and loss of herbaceous plant diversity) on the first three years of Bur Oak (Quercus macrocarpa) seedling performance in a field experiment in central Minnesota, USA. We found that loss of plant diversity decreased initial oak survival but increased overall oak growth. Conversely, elevated CO2 increased initial oak seedling survival and reduced overall growth, especially at low levels of diversity. Nitrogen deposition surprisingly had no net effect on survival or growth. The magnitude of these effects indicates that long-term woody encroachment trends may be most strongly associated with those few individuals that survive, but grow much larger in lower diversity patches. Further, while the CO2

Quantitative Phylogenetic Analysis in the 21st Century

WE REVIEW HENNIGIAN PHYLOGENETICS AND COMPARE IT WITH MAXIMUM PARSIMONY, MAXIMUM LIKELIHOOD, AND BAYESIAN LIKELIHOOD APPROACHES. ALL METHODS USE THE PRINCIPLE OF PARSIMONY IN SOME FORM. HENNIGIAN-BASED APPROACHES ARE JUSTIFIED ONTOLOGICALLY BY THE DARWINIAN CONCEPTS OF PHYLOGENETIC CONSERVATISM AND COHESION OF HOMOLOGIES, EMBODIED IN HENNIG´S AUXILIARY PRINCIPLE, AND APPLIED BY OUTGROUP COMPARISONS. PARSIMONY IS USED AS AN EPISTEMOLOGICAL TOOL, APPLIED A POSTERIORI TO CHOOSE THE MOST ROBUST HYPOTHESIS WHEN THERE ARE CONFL ICTING DATA. QUANTITATIVE METHODS USE PARSIMONY AS AN ONTOLOGICAL CRITERION: MAXIMUM PARSIMONY ANALYSIS USES UNWEIGHTED PARSIMONY, MAXIMUM LIKELIHOOD WEIGHT ALL CHARACTERS EQUALLY THAT EXPLAIN THE DATA, AND BAYESIAN LIKELIHOOD RELYING ON WEIGHTING EACH CHARACTER PARTITION THAT EXPLAINS THE DATA. DIFFERENT RESULTS MOST OFTEN STEM FROM INSUFFICIENT DATA, IN WHICH CASE EACH QUANTITATIVE METHOD TREATS AMBIGUITIES DIFFERENTLY. ALL QUANTITATIVE METHODS PRODUCE NETWORKS. THE NETWORKS CAN BE CONVERTED INTO TREES BY ROOTING THEM. IF THE ROOTING IS DONE IN ACCORDANCE WITH HENNIG´S AUXILIARY PRINCIPLE, USING OUTGROUP COMPARISONS, THE RESULTING TREE CAN THEN BE INTERPRETED AS A PHYLOGENETIC HYPOTHESIS. AS THE SIZE OF THE DATA SET INCREASES, LIKELIHOOD METHODS SELECT MODELS THAT ALLOW AN INCREASINGLY GREATER NUMBER OF A PRIORI POSSIBILITIES, CONVERGING ON THE HENNIGIAN PERSPECTIVA THAT NOTHING IS PROHIBITED A PRIORI. THUS, ALL METHODS PRODUCE SIMILAR RESULTS, REGARDLESS OF DATA TYPE, ESPECIALLY WHEN THEIR NETWORKS ARE ROOTED USING OUTGROUPS. APPEALS TO POPPERIAN PHILOSOPHY CANNOT JUSTIFY ANY KIND OF PHYLOGENETIC ANALYSIS, BECAUSE THEY ARGUE FROM EFFECT TO CAUSE RATHER THAN FROM CAUSE TO EFFECT. NOR CAN PARTICULAR METHODS BE JUSTIFIED ON THE BASIS OF STATISTICAL CONSISTENCY, BECAUSE ALL MAY BE CONSISTENT OR INCONSISTENT DEPENDING ON THE DATA. IF ANALYSES USING DIFFERENT TYPES OF DATA AND/OR DIFFERENT METHODS OF PHYLOGENY RECONSTRUCTION DO NOT PRODUCE THE SAME RESULTS, MORE DATA ARE NEEDED.
Genetic selection for avian embryo development at an elevated temperature

Hermes Anita4ft"rft"G-search Corv Life Science allis, OR 97331-7304 A genetic selection study to determine the effects on egg hatchability and subsequent chick performance of Japanese quail eggs incubated at a 38.9° C (102° F) dry bulb temperature (Selected, S) when compared to 37.8 C (100°F) (Control, C) was conducted for four consecutive generations. Eggs from a randomly mated population of Japanese quail were randomly allocated to the two treatment groups and incubated in dedicated Jamesway 252 units for the first 14 days then transferred to a common hatcher 36.9° C (98.5° F). Using family-based selection, the chicks that hatched from the two lines were subsequently used as breeders (25 pair matings/line) and the resulting eggs incubated at their respective temperatures. After four consecutive generations, percent egg fertility, percent early dead embryos (1 -7days), and percent hatch of fertile eggs were numerically higher in line C vs. S. While total development time was reduced in line S vs. C by 24 hours, mean egg weight and body weight were higher (p < 0.01) and age to first egg was reduced in line S. / Oregon State University Anita4 2rrrajcg_ e ©Copyright by Wendy R.

Holomitrium trichopodum (Bryophyta, Dicranaceae), a Holomitrium with split peristome teeth from Australia and New Zealand (Papers to Commemorate the 100th Issue of the Journal of the Hattori Botanical Laboratory) -- (Bryology)

Results of cladistic analyses of both ITS and trnL-trnF sequences, as well as peristome structure, suggest that the species currently recognised as Dicranoloma trichopodum (Mitt.) Broth. is affiliated to Holomitrium . A new combination, Holomitrium trichopodum (Mitt.) Klazenga, is proposed.
Artificial flowering in Triplochiton scleroxylon.

DJAGBLETEY GD, OFORI DA & COBBINAH JR. 2011. Artificial flowering in IHplochiton scleroxylon. Triplochiton scleroxylon is an important indigenous tropical hardwood species in West Africa. Due to its erratic flowering cycles, seeds are not readily available on a year to year basis, posing considerable difficulty in plantation establishment. To ensure abundance and continuous supply of planting stock, various treatments to induce flowering on grafts and mature trees were tested. These included spraying of urea solution on leaves, bark ringing and soil drenching with 2,4-dichlorophenoxyacetic acid solution. The studies were carried out in two agroecological zones in Ghana, namely, the dry and moist semi-deciduous ecozones. In the dry semi deciduous ecozone, fruiting occurred from November-December 2005 in girdled (80%) and ungirdled (30%) trees whereas in the moist semi-deciduous ecozone there was less fruiting, i.e. girdled (40%) and ungirdled (0%) trees in the same period. In all plants (30), the region within 10 cm above and below the girdles were swollen four months after girdling. Soluble carbohydrate concentrations in the bark before flowering were higher above the girdle (8.5%) than below (6.0%). Leaf shedding and bud development were greatest in treatments with 50, 37.5 and 25% urea compared with 12.5 and 0% urea. The results suggest that T. scleroxylon can be artificially induced to flower.
Molecular Rapid Diagnostic Test for Nosocomial Nonfermenting Gram-Negative Bacilli

Accurate diagnosis of nosocomial infections is crucial for appropriate antibiotic therapy, as well as avoiding unnecessary use of drugs. Mainly 3 gram-negative bacteria including Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia are involved in nosocomial infections. These bacteria are possibly misdiagnosed with together in traditional diagnostic methods. In this regard, a rapid molecular diagnostic kit was developed in Shiraz Burn Research Center. Using this diagnostic kit, the sensitivity and specificity analyses showed following results, respectively: P. aeruginosa: 100%, 96.8%; A. baumannii: 100%, 100%, and S. maltophilia: 96.7%, and 93.8%. Therefore, this multiplex polymerase chain reaction (PCR) method with 3 primer sequences could be a responsive technique in timely and appropriate detection of studied bacteria.
Exogenous salicylic acid modifies gas exchange and biomass production of Mentha x piperita L.

Peppermint (Mentha x piperita L.) is a medicinal plant that produces an essential oil used as an additive in food and pharmaceutical formulations. Salicylic acid is a phenolic compound widely distributed throughout the plant kingdom, being able to modify plant physiological and metabolic responses. The objective of this study was to evaluate the effects of the application of salicylic acid on the production of biomass, pigments, as well as gas exchange of peppermint plants. For this purpose, a completely randomized design composed of four replications was applied. Pigment evaluations were carried out in a 4x4 factorial scheme, consisting of the application treatments: 0 (control), 75, 150, and 225 mg L-1 of salicylic acid and four harvest periods. Gas exchange and physiological growth rates were evaluated in a 4x3 factorial scheme. Data were submitted to analysis of variance and regression. The application of salicylic acid increased CO2 assimilation and use, stomatal conductance, water use efficiency, and transpiration, which in turn, resulted in increased height, and dry stem and root mass production. It is concluded that the application of salicylic acid influences the primary metabolism, increasing gas exchange and biomass production of peppermint plants.
EFFECTS OF OMEGA-3 ADMINISTERED IN-OVO DURING INCUBATION ON SOME PHYSIOLOGICAL PARAMETERS OF THE DEVELOPING CHICK EMBRYOS

Total of 400 hatching eggs with an average egg-weight of 60.5 ± 1.5g from Hy-Line Brown Strain acquired from layer breeder flock (46 weeks of age) were used in this study to investigate the impact of in-ovo injection of omega-3 fatty acids on hatchability and some physiological and histological parameters of the developing chick embryos and newly hatched chicks. At the 10 day of embryogenesis, fertile eggs were allocated into four equal groups. In the 1 group, embryonated eggs did not receive any treatment and served as the control group. Eggs of the 2, 3 and 4 groups were injected into the yolk sac with 200μL sterile saline, 100 and 200μL of omega-3 fatty acids, respectively. Results revealed that in-ovo injection with low dose of omega-3 (100μl) resulted in a significant increase in the hatchability percent, embryonic and post-hatch body weight, serum total protein, globulin, thyroid hormones concentrations and total antioxidant capacity in the hepatic and brain tissues as compared with high dose of omega-3 (200μl), or control groups. While, significant increases in serum total lipids, cholesterol, triglycerides concentrations and alkaline phosphatase, alanine transaminase, and aspartate transaminase enzymes activities as well as harmful histological changes in hepatic tissues were observed in high dose of omega-3 (200μl). In conclusion, in-ovo injection with 100μl of omega-3 caused enhancement in hatchability, body weight, total antioxidant capacity of hepatic and brain tissues and some of the physiological aspects during embryonic development and at hatch.
