    Full Text Available Este trabalho teve como objetivo testar a eficiência de diferentes tratamentos para quebra da dormência e desinfestação de sementes de canafístula na realização do teste de germinação. O experimento foi realizado em esquema fatorial com três lotes × cinco tratamentos para quebra da dormência × quatro tratamentos de desinfestação das sementes. As sementes utilizadas foram coletadas nos municípios de Lavras-MG, em 1986 e 1998, e em Lins-SP, em 1998. Os tratamentos para quebra da dormência foram constituídos por escarificação manual com lixa, água quente (a- fervura das sementes por 3 minutos com imersão por 24 horas, fora do aquecimento; e b - imersão das sementes em água quente por 24 horas, fora do aquecimento e ácido sulfúrico (imersão por 15, 17, 20 e 30 minutos. Para desinfestação das sementes foram testados os tratamentos, utilizando Polyfluanide (0,2% por 30 minutos, Benomyl (0,02% por 1 minuto e hipoclorito de sódio (2% por 3 minutos. Foram utilizadas quatro repetições de 25 sementes em cada tratamento. O teste de germinação foi instalado sobre areia, na temperatura de 25 ºC, sob luz branca constante. As contagens de germinação (plântulas normais foram realizadas diariamente. O tratamento de imersão das sementes de canafístula em água quente (95 ºC e posterior permanência na mesma água por mais 24 horas, fora do aquecimento, é eficiente na promoção da germinação, sendo prático e dispensando o uso de tratamentos de desinfestação.

    Full Text Available O cobre é um metal pesado que pode exercer efeitos tóxicos para micro-organismos e plantas. Os fungos ectomicorrízicos são capazes de proteger a planta hospedeira da toxidez dos metais pesados, mas a presença de certas concentrações de metais pode inibir o crescimento destes, prejudicando a simbiose micorrízica e alterar o desenvolvimento das plantas. O objetivo deste trabalho foi avaliar o efeito de doses de cobre na população de bactérias e fungos do solo, bem como seus efeitos na associação ectomicorrízica e no desenvolvimento de mudas de eucalipto, pinus e canafístula. O levantamento da população de micro-organismos do solo foi realizado em casa de vegetação durante 60 dias e os tratamentos foram doses de sulfato de cobre aplicadas ao solo (0,7; 0,708; 0,716; 0,724 mg kg-1 de solo e mudas de eucalipto e pinus. No segundo experimento, mudas de eucalipto e canafístula inoculadas e não inoculadas com Pisolithus microcarpus (Cooke & Massee Cunn (UFSC Pt 116 receberam doses de cobre de 0, 100, 200 e 300 mg kg-1 de solo. Aos 110 dias, avaliaram-se a massa fresca da parte aérea e radicular, massa seca da parte aérea, altura, diâmetro do colo e porcentagem de colonização ectomicorrízica. No primeiro experimento, a população total de bactérias e fungos do solo foi alterada pela presença do cobre, porém as mudas de eucalipto e pinus não mostraram efeitos da adição do cobre. No segundo experimento, a inoculação das mudas de eucalipto e canafístula com o isolado UFSC Pt 116 favoreceu o desenvolvimento da massa fresca da parte aérea e radicular e a altura das plantas. Conforme os resultados obtidos, a canafístula foi capaz de realizar associação ectomicorrízica com o isolado testado. O desenvolvimento das plântulas de eucalipto e canafístula foi inibido pelos níveis de cobre, mesmo inoculadas com o isolado UFSC Pt 116.

    Full Text Available Copper is a heavy metal that can have toxic effects on microorganisms and plants. Ectomycorrhizal fungi are able to protect the plant from heavy metal toxicity, but the presence of certain metal concentrations can inhibit the growth of this fungus, damage the mycorrhizal symbiosis and also altering the development of the plants. The aim of this study was to evaluate the effect of copper on soil bacteria and fungus population, as well as the effects on the ectomycorrhizal association in the development of Eucalyptus grandis, Pinus elliottii and Peltophorum dubium seedlings. The survey of the soil microorganism population was carried out in a greenhouse during 60 days and the treatments consisted of applications of copper sulphate (0.7; 0.708; 0.716; 0.724 mg Kg-1 to the soil and to eucalyptus and pinus seedlings. Eucalyptus and Peltophorum dubium seedlings inoculated and not inoculated with Pisolithus microcarpus (Cooke and Massee Cunn (UFSC Pt 116 received copper levels of 0, 100, 200 and 300 mg kg-1. The height, stem diameter, shoot and root fresh biomass, shoot and root dry biomass and ectomycorrhizal colonization were evaluated at 110 days. Soil bacteria and fungus population were altered by the presence of copper and the eucalyptus and pinus seedlings were not affected by copper addition. The inoculation of the eucalyptus and canafístula seedlings with isolate UFSC Pt 116 favored the height of the plants and the development of shoot and root fresh biomass. According to the results, canafístula was able to form an ectomycorrhizal association with the isolate tested. The eucalyptus and canafístula seedling development was inhibited by copper following inoculation with the UFSC Pt 116 isolate.

    Full Text Available Open source software is software designed to allow anyone to use and make changes in the software. This practice often renders the product superior to more centralized models such as those used in commercial software companies. How is such a phenomenon possible in a time where nothing seems to be acquirable save by purchase? Niels C. TAUBERT's book Productive Anarchy? Networks of Open Source Software Development aims at a sociological understanding of the prerequisites and conditions for the success of open source software. One of the conclusions of TAUBERT's book is that the process of open software development needs to be understood as adaptive and experimental. A continuous feedback between the context of production and the context of application is the basis for robust and successful software production. One of the surprising results of the book is that the most important requirement for this feedback process is a set of norms—neutrality, communism, disinterestedness, and universalism—norms that Robert MERTON associated with academic science in the 1940s. If TAUBERT is right that these norms are to be found outside the world of institutional science in open source software development projects today, then his case study can be seen as an indicator for a new form of knowledge production in the 21st century, where the social relevance and responsibility of a research process are keys to successful innovation. With this book, which deserves a wide readership, TAUBERT makes an important contribution to our understanding of the successful organization of technology development.

    Origanum dubium Boiss. is a flavouring herb widely used in Cyprus. In this study, both lipophilic and polar extracts of the aerial parts of O. dubium were investigated for their chemical contents and their antioxidant potential. Overall, 20 constituents were isolated and identified, belonging mainly to three significant classes of compounds: terpenes, phenolic derivatives, such as hydroquinone glycosides and flavonoids and alicyclic derivatives. None of them was previously reported as constituent of O. dubium The inhibitory potencies of all total extracts and the isolated compounds on lipid peroxidation and their interaction with 1,1-diphenyl-picrylhydrazyl (DPPH) activity is discussed. The polar extract showed strong interaction with DPPH stable radical and significant inhibition of lipoxygenase and lipid peroxidation.

    Full Text Available Background. Sprengel's deformity is a rare congenital anomaly of the shoulder girdle. The deformity is due to failure of descent of the scapula in intrauterine life. Case Presentation. We report a case of unilateral Sprengel's deformity associated with several other musculoskeletal and renal disorders consisting of absence of pectoralis major, weakness of trapezius and serratus anterior muscles, one kidney agenesis, and severe hydronephrosis of the other kidney in a 7-year-old boy. Conclusion. Sprengel's deformity can be associated with other musculoskeletal abnormalities and it is much more than a cosmetic problem.

    Sprengel's deformity, a rare congenital malformation of the scapula, may be observed in combination with spinal dysraphism. The co-occurrence of these malformations suggests an unknown shared etiology. Therefore, we reviewed the medical records of eight children presenting with both malformations and performed a review of the literature. Databases from four university medical centers were searched for children presenting between 1992 and 2012 with spinal dysraphism and a Sprengel's deformity. The combination of spinal dysraphism and Sprengel's deformity is rare, and is associated with segmentation defects of the spine and ribs. Although the etiology of both spinal dysraphism and Sprengel's deformity remains unclear, all deformities of the spine, ribs, and shoulder might result from a common genetic defect affecting somitogenesis.

    Full Text Available O presente trabalho teve por objetivo avaliar o comportamento da canafistula (Peltophorumdubium, em semeadura direta a campo, em área de capoeira originada após o abandono do local utilizado com cultivos agrícolas sucessivos. No local foram roçadas faixas de 1,5 m, a cada 3 m. A semeadura foi realizada em setembro de 1997. Visando proteger os pontos semeados, foram utilizados diferentes tipos de protetores (copos de plástico e copos de papel, sem fundo e laminado de madeira, fixados sobre os pontos semeados com três sementes cada. As sementes foram escarificadas mecanicamente a 1.725 rpm, durante 60 segundos, com lixa Norton 60. O delineamento foi em blocos casualizados, com seis repetições. As variáveis avaliadas foram emergência, sobrevivência, número de pontos com plantas, densidade a 1 ano e altura das plantas aos 18 meses. Os resultados obtidos aos nove meses demonstraram que a utilização de qualquer um dos protetores físicos contribuiu para o estabelecimento de plantas em mais de 80% dos pontos semeados, e em mais de 75%, um ano após a semeadura, quando utilizado o laminado, o que indica que a semeadura direta é uma alternativa de implantação para a espécie, possibilitando transformar as áreas de capoeiras em um sistema agroflorestal ou mesmo silvipastoril, no futuro.This work aimed to evaluate the development of Peltophorum dubium by direct seeding on a succesively cropped field. Seeding was performed in rows of 1.5 m, three meters apart, on September 1977. To protect the seed-spots shelters, bottomless paper and plastic cups were used and wood slates were fixed on them. Seeds were mechanically scarified for 60 seconds. The variables evaluated were emergence, seedling survival, number of seed-spots with plants plant density at one year and plant height at the 18th month. Results at the 9th month showed that the seed-spot shelters contributed for plant establishment in 80% of the seed-spots and in more than 75% of them

    Peltophorum dubium seeds were set to imbibe with four treatments, soaked with solution Captan 0.2% under 10and 27℃,PEG 6000 -1.0 MPa under 10 and 27℃. For each treatment there were four replicates with 40 seeds incubated in 9-cm Petri dishes with double filter paper moistened with testing solution. The imbibition curves showed that the final weight increase were from 70% to 150% in the treatments when imbibition entered a lag phase. Seeds were tested for effects on germination of five treatments: control group (nonprimed), primed with PEG6000 -1.0 MPa at 10 and 27℃, primed with Captan 0.2% at 10 and 27℃. For each treatment, there were three sub-treatments: seeds were soaked in distilled water for 12, 24 and 36h before the energy test. Germination percentages of nonprimed seeds and primed in PEG 27℃ soaked in distilled water during 12 h were the highest, reaching 100%. The lowest germination percentage occurred primed seeds with PEG6000 27℃ and soaked in distilled water during 36 h, which was only 52%. Germination mean time of primed seeds in PEG at 10℃, soaked 24 h was 1.08 days, mean time of primed seeds in PEG at 27℃ soaked 12 h was 2.42 days. Accelerated ageing results showed low or no germination after ageing 72 h. Control group had a higher germination percentage and seeds were more resistant to deterioration than those in primed groups, both in Petri dish (27℃) and vermiculate (room temperature).

    Full Text Available Vitex megapotamica (Sprengel Moldenke belongs to the Verbenaceae family and is popularly known as “tarumã”. The antioxidant capacity of fractions and crude extract from the leaves of V. megapotamica were determined in this study through the capacity to remove reactive species and phenolic compounds were quantified in the various fractions. The IC50 (DPPH ranged from 14.17 ± 0.76 to 37.63 ± 0.98 µg/mL. The ethyl acetate fraction might contain the strongest lipid peroxidation inhibitory compounds with an IC50 of 16.36 ± 5.09 µg/mL, being also the one with the highest content of polyphenols (522.4 ± 1.12 mg/g, flavonoids (220.48 ± 0.30 mg/g and condensed tannins (3.86 ± 0.53 mg/g. Compounds quantified by HPLC/DAD in the crude extract and fractions were chlorogenic and rosmarinic acids. Higher dosages of the extracts were more effective in reducing levels of plasma protein carbonyls and were also shown to be able to remove reactive species by a 2',7'-dichlorofluorescein diacetate assay, reducing oxidative stress in all tested fractions. Results obtained indicated that V. megapotamica exhibits good potential to prevent diseases caused by the overproduction of free radicals and it might also be used as a potential source of natural antioxidant agents.

    Full Text Available Herbal medicine is an ancient practice that has been gaining acceptance of the medical class through scientific studies that prove its effectiveness. However, its use should still be cautious. Medicinal plants have potential toxic effects not yet discovered, and may have unproven interactions with other medications. The use of drugs during pregnancy is still very dangerous and vigorously studied; however, there are few studies of herbal medicines in pregnant women. Existing studies prioritize on teratogenic or abortifacient effects. The aim of this study was to analyze the toxic effects of Mikania glomerata Sprengel administration, popularly known as “guaco” during the gestational period of hypertensive rats. For this experimental groups consisting of pregnant Wistar rats received treatments with guaco extract (1 to 2 mL. In order to analyze the possible toxic effects of guaco during pregnancy, weight gain of rats was assessed during pregnancy; reproductive performance of rats, morphological parameters, and fetal placental histology were compared. Although some parameters presented significant differences, we can conclude that changes prioritized by literature, such as toxicity, vasodilation and hypotension, have not been caused by guaco. The only fetal changes observed were due to the maternal hypertension. Some studies have reported vasodilator and hypotensive effects of guaco. However, only a few studies exist, and its actual effects remain unknown. Specific studies should be developed with higher doses of guaco for a definitive conclusion of its toxic and non-toxic effects.

    Vitex megapotamica (Sprengel) Moldenke belongs to the Verbenaceae family and is popularly known as "tarumã". The antioxidant capacity of fractions and crude extract from the leaves of V. megapotamica were determined in this study through the capacity to remove reactive species and phenolic compounds were quantified in the various fractions. The IC50 (DPPH) ranged from 14.17 ± 0.76 to 37.63 ± 0.98 µg/mL. The ethyl acetate fraction might contain the strongest lipid peroxidation inhibitory compounds with an IC50 of 16.36 ± 5.09 µg/mL, being also the one with the highest content of polyphenols (522.4 ± 1.12 mg/g), flavonoids (220.48 ± 0.30 mg/g) and condensed tannins (3.86 ± 0.53 mg/g). Compounds quantified by HPLC/DAD in the crude extract and fractions were chlorogenic and rosmarinic acids. Higher dosages of the extracts were more effective in reducing levels of plasma protein carbonyls and were also shown to be able to remove reactive species by a 2',7'-dichlorofluorescein diacetate assay, reducing oxidative stress in all tested fractions. Results obtained indicated that V. megapotamica exhibits good potential to prevent diseases caused by the overproduction of free radicals and it might also be used as a potential source of natural antioxidant agents.

    Full Text Available Mikania glomerata Sprengel is a medicinal plant widely used in folk medicine, mainly to treat respiratory disorders, which acts by dilating the bronchi, being coumarin one of the substances associated with this effect. Therefore, understanding the physiological behavior of this species and its responses to the environmental conditions is necessary to improve the cultivation methods. In this context, the aim of this work was to evaluate the effect of light spectrum control on growth, the essential oil content, and the content of coumarin in Mikania glomerata Sprengel. Plants were grown for four months under nets with 50% shading in gray, red, blue, and exposed to full sunlight (0%. The essential oil was extracted from fresh leaves through hydrodistillation in a modified Clevenger apparatus. The identification and quantification of coumarin were performed through high performance liquid chromatography (HPLC. The results showed the blue fabric allowed an increase in total dry matter accumulation and leaf area, as plants under red shading presented higher dry matter allocation to the roots. The smallest quantity of dry leaves was observed in plants grown under full sun exposure. Changes were not observed, however, in leaf weight ratio and in root/shoot proportion. The essential oil content of plants grown under blue net was 0.14%, which corresponded to an increase of 142% over the level found in plants grown under full sun exposure, as the coumarin content was not influenced by the net color. These results show that light can be modulated during cultivation, in order to obtain desirable morphological characteristics and maximize the production of active principles in this species.

Three different types of commercial SPME fibers were tested: polydimethylsiloxane (PDMS, polydimethylsiloxane/divinylbenzene (PDMS/DVB and polyacrylate (PA. Fifty-nine compounds were fully identified by HS-SPME-HRGC-MS, including coumarin, a marker for the quality control of guaco-based phytomedicines; most of the other identified compounds were mono- and sesquiterpenes. PA fibers performed better in the analysis of coumarin, while PDMS-DVB proved to be the best choice for a general and non-selective analysis of volatile and semi-volatile guaco-based compounds. The SPME method is faster and requires a smaller sample than conventional hydrodistillation of essential oils, providing a general overview of the volatile and semi-volatile compounds of M. glomerata.

    Cochlospermum vitifolium (Willd.) Sprengel is a Mexican medicinal plant that is used in the folk medicine for the treatment of hypertension, diabetes, hepatitis and related diseases. The purpose of the present study was to assess the pharmacological properties of different extracts from Cochlospermum vitifolium bark as potential agent for the treatment of some factors related with metabolic syndrome (MS), a complex disease produced for several pathophysiological factors such as visceral fat obesity, insulin resistance, hypertension, dyslipidemia and liver steatosis. Hexane (HECv), dichloromethane (DECv) and methanol (MECv) extracts were subjected to some pharmacological assays to determine their vasorelaxant and hypoglycemic activity. On the other hand, MECv was also evaluated to determine its hepatoprotective effect on sub-chronic experimental assay. HECv showed a significant endothelium-independent relaxation on rat aorta rings (intact endothelium: IC(50)=14.42+/-5.90 microg/mL, E(max)=92.71+/-8.9%; denuded endothelium: IC(50)=27.94+/-4.0 microg/mL, E(max)=78.68+/-4.6%) and MECv produced an endothelium-dependent relaxation (IC(50)=21.94+/-6.87 microg/mL, E(max)=79.12+/-7.80%) on this tissue. Furthermore, HECv (at a dose of 120 mg/kg) also showed a significant decrease of blood glucose levels (p<0.05) on normoglycemic rats. Moreover, MECv (at a dose of 100 mg/kg) also was administered to bile duct-obstructed rats to determine its hepatoprotective activity, showing a statistically significant decrease of serum glutamic-pyruvic transaminase (PGT, 45%) and alkaline phosphatase (APh, 15%) (p<0.05). Finally, we obtained a crystalline polyphenolic compound from MECv by spontaneous precipitation. Those crystals were identified as (+/-)-naringenin by X-ray diffraction, NMR, IR and GC-MS techniques. Results suggest that Cochlospermum vitifolium could be used as a potential agent against MS since it shows hypoglycemic, vasorelaxant and hepatoprotective properties.

    @@ 前言 先天性脊柱侧凸(congenital scoliosis,CS)伴高肩胛症(Congenital elelvation of the scapula,Sprengel'sdeformity)是一种少见而复杂的先天性发育畸形.Tsirikos等[1]分析了537例先天性脊柱畸形患者的肋骨、胸廓及肩胛畸形,在497例CS患者中43例(8.6%)合并高肩胛畸形.Cavendish等[2]报道的100例先天性高肩胛症患者中,有39例(39%)伴CS;与单纯的先天性高肩胛症或CS相比,CS伴高肩胛症的临床评估及手术策略更加复杂,现对这种复杂畸形的临床评估与手术策略作一综述.%Congenital scoliosis (CS) combined with the Sprengel's deformity was a rare and complicated congenital deformity. Although the pathogenesis of this complicated deformity was still unclear, some existing studies revealed that Sprengel's deformity occurred most frequently in congenital scoliosis with unilateral failure of vertebral segmentation in cervicothoracic or thoracic segments. According to the relationship between the congenital scoliosis and the Sprengel's deformity, the complicated congenital deformity could be divided into 3 types: the elevated shoulder occurred on the convex side of the scoliosis, on the concave side of the scoliosis and CS combined with bilateral Sprengel's deformity. A thorough physical examination and comprehensive using of three-dimensional computed tomography (CT) and magnetic resonance imaging (MRI) were very important for the assessment of this complicated deformity. The Sprengel's deformity occurred on the convex side of upper thoracic congenital scoliosis usually required one-stage surgery to elevate scapula and correct the spinal deformity. The one-stage reduction of the elevated scapula was not necessarily needed when the Sprengel's deformity occurred on the concave side of the scoliosis, because the elevated scapula could partially compensate the cosmetic deformity and minimize shoulder asymmetry.

    Full Text Available Guaco (Mikania glomerata Sprengel syrup is one of the most popular herbal medicines used to treat the symptoms of asthmatic bronchitis, cough and hoarseness. The coumarin 2H-1-benzopyran-2-one, is one of the major constituents of Guaco and contributes to its pharmacological effects. The pharmaceutical capsule form of dry extract of Guaco is recommended by the Brazilian Program of Medicinal Plants and Herbal Medicines and used in primary health care. In order to identify a new protocol to obtain the raw material for Guaco capsule production we evaluated two methods, including a freeze-drying process (lyophilization and the spray-dryer technique, as well as the use of two adjuvants, Maltodextrins and Aerosil®, in different concentrations. The coumarin levels of the dried extracts were analyzed by UV-spectrophotometry and HPLC-UV/DAD. The adjuvant Aerosil® 8% showed better dry powder physical appearance. Lyophilization was observed to be the best process to obtain the dry extract of Guaco based on the measured coumarin levels.

  9. Sapientiam sine eloquentia prodesse non est dubium: the rapport of wisdom and eloquence in the work of Isidore of Seville

    Directory of Open Access Journals (Sweden)

    Elena Marey

    2013-02-01

    Full Text Available The works of Isidore of Seville reveal several levels of knowledge. The fi rst and the highest is wisdom (sapientia, which according to Isidore, is knowledge of divine things. This wisdom will most definitely lead the initiate to salvation and the Kingdom of Heaven. But the specific quality of wisdom is interpreted by Isidore in diff erent ways according to his various works. In those works which possess an encyclopedic character («Etymologies» and the first book of «Differences», wisdom involves an understanding of how the world and the whole of the cosmos are organised. A wise man is able to comprehend the causes of both the visible and the heavenly world. On the contrary, a person’s rationality (prudentia is oriented towards worldly and secular things. It aims at distinguishing between good and evil and how best to arrange one’s own life and final destiny. Rationality is connected with knowledge (scientia, which is bookish learning, and which Isidore treats as a part of philosophy. At the same time, rationality and knowledge act as instruments for the gaining of wisdom (sapientia. Thus wisdom is linked also with the art of speaking well (eloquentia. In his works meant for a clerical readership, particularly the second book of the «Differences» and the «Sentences», wisdom is opposed to vain mundane knowledge. In these works Isidore affirms that mere eloquence is alien to wisdom and that true wisdom is to be cherished precisely because of its lack of pretention. In the context of these works, wisdom is geared only to the living of a devout life and towards the final aim of the salvation of one’s soul. The differences in the interpretation of the word sapientia can be easily explained by the differences in literary genre among the various works as well as by the readers for whom the various works were intended by the author.

    By using isolation and culture method, 25 strains of dominant bacteria in Ageratina adenophora rhizosphere soil were isolated and identified, of which, 8 strains were assessed for their antagonistic activity. The results showed that Bacillus and Pseudomonas were highly abundant in A. adenophora rhizosphere soil, of which, B. subtilis and B. megaterium were most abundant and occupied 55.6% of the total identified bacteria. These dominant bacteria had different level antagonistic activity to Fusarium oxysporum and Ralstonia solanacearum, and B. subtilis BS-5 and B. thuringiensis BT-1 had the strongest antagonistic effect on F. oxysporum, with the antagonistic activity of their metabolic products being 85.5% and 83.8%, respectively. The metabolic products of the dominant antagonistic bacteria had even more stronger antagonistic effect on pathogens than the dominant antagonistic bacteria themselves. The existence of abundant bacterial groups with strong antagonistic activity in A. adenophora rhizosphere soil could help A. adenophora to resist harmful soil-borne diseases and escape its natural enemies. Through the feedback actions of the beneficial rhizosphere microbes, A. adenophora probably earned its competition superiority directly or indirectly, being favorable to its rapid expansion.

Eggs, newly hatched and 30 day old snails were exposed to the sublethal concentration of M. glomerata extract for 24 and 48 h and the observations were made for 120 days. The presence of tannins, flavonoids and saponins were shown by phytochemical tests. The extract reduced significantly the hatchability and the survival of the offspring hatched from the exposed eggs. The eggs exposed for 48 h presented lower hatchability rates. There was a reduction on survival and growth of newly hatched and 30-days old snails exposed to the extract. These results indicated that the aqueous extract of M. glomerata could be applied as an alternative molluscicide for the control of this snail species efficiently.

    Full Text Available Para avaliar a influência da luz e da temperatura na germinação de sementes de Cochlospermum vitifolium, frutos maduros foram coletados de 12 plantas matrizes. Os tratamentos foram mantidos em câmaras de germinação equipadas com lâmpadas fluorescentes brancas, num arranjo fatorial 2 × 4, constituídos por duas condições de luminosidade, com fotoperíodo de 8 h de luz e 16 h de escuro, e escuro completo, distribuídos em quatro regimes de temperatura, sendo três temperaturas constantes (20, 25 e 30 ºC e uma temperatura alternada (20-30ºC, utilizando-se um modelo inteiramente casualizado, com quatro repetições de 50 sementes. Efetuaram-se contagens diárias até o 14.º dia após a semeadura, para avaliação da porcentagem de germinação, do índice de velocidade e do tempo médio de germinação. Conclui-se que as sementes de Cochlospermum vitifolium são fotoblásticas neutras e a temperatura constante de 20 ºC é a condição mais adequada para a germinação da espécie.

    Full Text Available Adulterações da matéria-prima vegetal ocorrem comumente no mercado de fitoterápicos, sob a forma de substituições e/ou falsificações. Muitas vezes, espécies distintas são comercializadas em substituição à farmacopéica devido à dificuldade de obtenção desta, ou mesmo pelo emprego intencional de espécies de menor valor econômico que apresentem características morfológicas semelhantes. Portanto, faz-se necessária a realização de estudos que busquem identificar a constituição química das espécies de amplo uso medicinal, que são alvos de adulterações. Mikania glomerata e Mikania laevigata, conhecidas popularmente como "guaco", são comercializadas indistintamente. Buscando-se avaliar a composição química das duas espécies, realizou-se uma prospecção fitoquímica por CCD e foram obtidos os perfis cromatográficos por CLAE-FR. Fez-se a quantificação da cumarina empregando-se o mesmo método. Na prospecção fitoquímica por CCD, foi detectada, nas duas espécies, a presença de cumarina, triterpenos/esteróides e heterosídeos flavônicos. Os perfis cromatográficos, obtidos por CLAE-FR, mostraram-se semelhantes, observando-se a predominância de compostos polares. Na quantificação da cumarina, obtêve-se um teor de 0,30% para M. glomerata e 0,43% para M. laevigata, teores de acordo com o preconizado na monografia do guaco-cheiroso (mín. 0,1%. M glomerata e M. laevigata apresentaram composição química semelhante e teores de cumarina próximos, sugerindo que estas podem ser utilizadas de forma indistinta.Adulterations of plant raw materials often occur in the marketing of herbal medicine, usually in the form of substitutions and/ or fakes. Many times, different plant species are commercialized in the place of the one recognized by the pharmacopoeia. This may occur due to the difficulties of obtaining the authentic plant material, or by an intentional use of a plant species that has less economic value but shows similar morphologic features. Therefore, it is necessary to carry out studies that can identify the chemical composition of those species of wide medicinal use, which are the targets of adulterations. Mikania glomerata and Mikania laevigata, popularly known as "guaco", are indistinctly commercialized in Brazil. A phytochemical screening by TLC was carried out to evaluate the chemical composition of both species. The RP-HPLC profiles were obtained and the quantification of coumarin was determined by the same method. A phytochemical screening has shown that coumarin, triterpenes/ steroids and flavonic heterosides are the constituents detected in both species. The RP-HPLC profiles were similar between the two species and revealed the predominance of polar compounds. In the quantification of coumarin, a content of 0.30% (w/w was obtained for M. glomerata and 0.43% (w/w for M. laevigata. These values are in accord with the contents (min. 0.1%, w/w described by the monograph of "guaco-cheiroso" in the Brazilian Pharmacopoeia. Therefore, the results indicated similar chemical profiles for M. glomerata and M. laevigata, as well as comparable coumarin contents, thus suggesting that the species might be used indistinctly.

  11. Developmental anomalies of the scapula-the "omo"st forgotten bone.

    Science.gov (United States)

    Williams, Marc S

    2003-08-01

    Congenital malformations of the scapula, ranging from complete absence, to abnormal shape and position (Sprengel anomaly) are encountered, not infrequently, in genetic practice. Despite this, little is known of the embryologic origin of the scapula and the relationship of the embryology to the observed birth defects. Standard embryology texts, when discussing the subject at all, generally consider the scapula as part of the upper limb. The pattern of associated birth defects suggests that this is at least an oversimplification and may be inaccurate. Sprengel anomaly is the most frequently encountered malformation of the scapula. It can be seen in isolation, but is often seen in association with other defects that include; scoliosis, hemivertebrae, segmentation abnormalities of vertebrae and ribs (including Klippel-Feil sequence), spina bifida, clavicular abnormalities, renal abnormalities and hypoplasia of the muscles of the neck and shoulder. The ipsilateral limb is usually normal. An unappreciated association between Sprengel anomaly and diastematomyelia of the lumbar spine also raises questions about the embryologic origin of the scapula. 25-50% of Sprengel anomaly patients have an associated omovertebral band or bone that arises from the posterior process of a vertebral body and attaches to the superior angle/medial portion of the scapula. This is felt to be of scapular origin, but the report of at least one patient with an omovertebral bone, not associated with a Sprengel anomaly questions this assumption. Scapuloiliac dysostosis (Kosenow syndrome), a rare skeletal dysplasia, is associated with marked hypoplasia of the scapulae, clavicles and pelvis. Associated anomalies include eye anomalies, rib anomalies and spina bifida. The limbs are normal. Knockout of the Emx2 gene in mice yields a similar skeletal phenotype. Mutations in EMX2 in humans are associated with schizencephaly, not skeletal anomalies. Data on gene expression in the scapula will be reviewed

    Functionalised aromatic constituents of Chukurovo resinite are compared here with the chemical composition of a macrofossil assigned paleobotanically as Taxodium dubium (Sternb.) Heer. Terpenoids and lipids of fossil wood tissue embedded in a clay sediment were extracted and analyzed for comparison. The information was interpreted in relation to the biomarker compositions of different conifer families, as well as to the effects of contamination by inward migration of organic matter from the adjacent sediments. Many of identified geolipids, i.e., alkanes, alkanols, alkan-2-ones, and steranes/triterpanes have no chemosystematic value because they are ubiquitous in the plant kingdom. Ferruginol, sugiol, and products of their diagenetic transformations were identified as the dominant specific biomarkers in the resinite. Ferruginol and its analogues were the most abundant diterpenoids in Taxodium dubium sample. Thus, the biomarker composition of the extractable matter of the resinite strongly suggests that species of Cupressaceae contributed significantly to the Chukurovo paleoenvironment. (author)

    Full Text Available From the Middle Romanian lacustrine deposits of the Oltenia province, the authors describe the youngest fossil flora known until now in Oltenia. The inventory of the fossil flora includes the following taxa: Taxodium dubium, ?Platanus platanifolia, Ulmus laevis, Quercus roburoides, Q. cf. muehlenbergii, Carya serraefolia, Acer cf. tricuspidatum and Salix sp. In the Bâcleş fossil flora, Glyptostrobus europaeus, which is a thermophilous and shows a high frequency in all Oltenia area till the XV-th coal seam, is absent. Consequently, having in view the high frequency of Taxodium dubium, which indicate temperate climate conditions, the other consider that the fossil flora from Bâcleş is much more younger and marks an important cooling. From palaeofloristic point of view, the study of Bâcleş fossil flora is indicative for river meadow forest and, probably, flat plain forest environments.

    Congenital clefts and aplasias of the atlas vertebra are rare. A nonfused posterior arch occurs in 4% of the population; in contrast, a nonfused anterior arch occurs in only 0.1%. To the best of our knowledge, this is the first description of the combination of anterior arch aplasia and a cleft of the posterior arch of the atlas associated with Klippel-Feil and Treacher-Collins syndromes and Sprengel deformity. An 11-year-old girl presented with neck pain and symptoms of myelopathy, including upper- and lower-extremity paresthesia. Computed tomography revealed significant congenital bony anomalies of the cervical spine, with congenital fusion of C2 through C5. There was aplasia of the anterior ring of C1 (A 2.3-cm gap was present within the anterior aspect of the lateral masses). The posterior elements of C3 and C4 were fused, and signs of Sprengel deformity were present. Magnetic resonance imaging revealed effacement of the ventral cerebrospinal fluid space at the craniocervical junction and mild mass effect at the cervicomedullary junction. Flexion and extension views showed abnormal motion at the craniocervical junction. There was no evidence of atlantoaxial instability, basilar invagination, or Chiari malformation. Occipito-C4-scapular fusion was performed to prevent spinal cord injury and further neurological symptoms. Postoperatively, the patient did extremely well, and her preoperative symptoms resolved. We describe a rare case of aplasia of the anterior arch of the atlas and posterior arch midline cleft in association with Treacher-Collins syndrome, Klippel-Feil syndrome, and Sprengel deformity. The patient's atlantoaxial instability was managed surgically with a unique construct that provided occipito-C4-scapular fusion.

The termites present were: Odontotermes horni (Wasmann) (Isoptera: Termitidae), O. feae, O. wallonensis, and O. obeus (Rambur). A significant conelation was found between density, cellulose, lignin, and total phenolic contents of the wood and degradation by termites. The higher the density of the wood, the lower the degradation. Similarly, higher amount of lignin and total phenolic contents ensured higher resistance, whereas cellulose drives the termites towards the wood.

    The toxicity of 5 Sudanese plants credited with medicinal value for man, i.e. Citrullus colocynthis, Jatropha aceroides, J. glauca, Solanum dubium and Lagenaria siceraria, was studied by giving the dried or minced plants to Nubian goats, Desert sheep or Zebu calves by mouth or stomach tube. The clinical, haematological and pathological changes indicated that all five plants reduced the ability of the liver to synthesize protein, although there was no evidence of interference with the excretion of bilirubin. Kidney dysfunction and haemoconcentration also occurred. Citrullus colocynthis and Jatropha species in doses of 0.5 to 10 g per kg per day killed goats after dosing for periods ranging from 1 day to 2 weeks. Calves were less susceptible. The fruits and leaves of L. siceraria, in doses of 1 to 5 g per kg per day, caused death after a similar period but with less regularity. The seeds were less toxic. The fruits of S. dubium in doses of 2.5 to 10 g per kg per day killed goats in 2 to 5 days. Similar doses of the leaves caused deaths in 8 to 36 days. In sheep, both fruits and leaves required a longer period of dosing to cause death.

    The isolated aplasia of the serratus anterior muscle with winging of scapula is very rare, and only a few cases are reported. Here, we present a case of a 30-year-old Korean male who initially presented with a left flank pain. His physical exam did not show any significant finding in his right shoulder. However, his chest radiograph showed absence of right serratus anterior muscle and slightly elevated and medially rotated right scapula. Subsequent CT scan showed the right serratus anterior muscle aplasia and medial winging of the right scapula. This case is unique in two aspects. First, the combination of abnormalities is different from the typical congenital abnormalities involving shoulder girdle, such as Sprengel deformity or Poland syndrome. Secondly, this was incidentally diagnosed with chest radiograph, without clinical impression. Careful reading of chest radiograph can help the radiologists to detect such clinically silent abnormalities.

    Biguanides such as metformin are widely used worldwide for the treatment of type-2 diabetes. The identification of guanidine and related compounds in French lilac plant (Galega officinalis L.) led to the development of biguanides. Despite of their plant origin, biguanides have not been reported in plants. The objective of this study was to quantify biguanide related compounds (BRCs) in experimentally or clinically substantiated antidiabetic functional plant foods and potatoes. The corrected results of the Voges-Proskauer (V-P) assay suggest that the highest amounts of BRCs are present in green curry leaves (Murraya koenigii (L.) Sprengel) followed by fenugreek seeds (Trigonella foenum-graecum L.), green bitter gourd (Momordica charantia Descourt.), and potato (Solanum tuberosum L.). Whereas, garlic (Allium sativum L.), and sweet potato (Ipomea batatas (L.) Lam.) contain negligible amounts of BRCs. In addition, the possible biosynthetic routes of biguanide in these plant foods are discussed.

    Klippel-Feil syndrome (KFS) displays congenital fusion of the cervical vertebrae; it is a relatively common condition and has many associated malformations such as Sprengel's deformity, scoliosis, rib anomalies, congenital defects of the brain or spinal cord, renal anomalies, congenital heart disease, deafness, cleft palate, cranial and facial asymmetry, and enteric cysts. There are various types of cervical fusion observed in KFS. However, fusion of the odontoid process with the atlas is a very rare finding. We report here on a 4-year-old boy with unilateral fusion of a separated odontoid process with the lateral mass of the atlas, and this was associated with a spontaneously closed ventricular septal defect, a small patent ductus arteriosus and a horseshoe kidney.

    Alpheus Hyatt named a considerable number of Jurassic fossils from California. Only a few of these were described, arid none were illustrated. In this paper 16 of these species are evaluated in terms of present-day nomenclature, figures of the type specimens are shown, and their probable age significance is given. Included are Monotis semiplicata (=Entolium semiplicata),Monotis symmetrica (=Entolium symmetrica), Daonella?subjecta ( = '' Daonella" subjecta), Daonella bOchiformts (=" Daonella" bOchiformis), Daonella cardinoides (="Duonella"cardinoides), A ucella erringtoni var. arcuata ( = Buchia arcuata), Aucella elongata ( = Buchia elongata), AuceUa var.elongata orbicularis ( = Buchia sinzovi), Aucella aviculaeformis ( = Buchia erringtoni var. aviculaeformis), Aucella aviculaeformis var. acuta ( = Buchia erringtoni var. orbicularis), Aucella orb·.icularis( = Buchia erringtoni var. orbicularis), Cardioceras dub\\~um ( = Amoeboceras dubium), Perisphinctes virgulatiformis ( = Viigatosphinctes virgulatiformis), Perisphinctes miihlbachi ( = Dichotomoceras miihlbachi), iJlcostephanus lindgreni ( =" Galilaeiceras"

    The tardigrade class Mesotardigrada was erected on the basis of the description of Thermozodium esakii by Gilbert Rahm in 1937. In some characteristics, T. esakii is intermediate between members of the classes Eutardigrada and Heterotardigrada. The class Mesotardigrada is known only from Rahm's published drawings of T. esakii; no voucher specimens are known, and subsequent attempts to collect it at the locus typicus have been unsuccessful. Among the possible explanations for this situation are that Rahm may have collected specimens of a more typical tardigrade, but misinterpreted what he saw. Alternatively, changes in habitat in the area may have led to the tardigrade's extirpation. Perhaps T. esakii is a rare species, such that recent sampling efforts have been insufficient to rediscover it. Finally, Rahm's 1937 description may be an attempt at deception. Until physical evidence of T. esakii is found, the species, and by extension the class Mesotardigrada, should be considered nomen dubium.

    In a comparative study of different populations of Xiphinema, the significance of the female gonad structure in species determination is stressed, and monodelphic, pseudomonodelphic, and didelphic forms in the genus are defined. X. chambersi is redescribed and illustrated, X. ensiculiferum and X. krugi are redefined, and X. ensiculiferoides n.sp. and X. orthotenum n.sp. are described. Proposed new synonymies are: X. itanhaense = X. brasiliense; X. bulgariensis and X. conurum = X. italiae; X. ifacolum = X. basiri; X. macrostylum = X. ensiculiferum; X. truncatum = X. elongatum; and X. vulgare = X. setariae. X. yapoense is considered species inquirenda and X. obtusum a nomen dubium. The following eight subgenera of the genus Xiphinema are proposed: Radiphinema n. subg., Krugiphinema n. subg., Xiphinema n. subg., Elongiphinema n. subg., Halliphinema n. subg., Basiphinema n. subg., Rotundiphinema n. subg., and Diversiphinema n. subg. A key to the subgenera of Xiphinema is presented, plus a list of 50 species in the genus, their synonyms, and 10 species inquirendae.

    Full Text Available An overlooked error in the correlation of new scientific names with the spider images on plate 4 in Carl Wilhelm Hahn’s sixth instalment of his book ”Monographie der Spinnen” led to the notion that at least two of the spiders illustrated on plate 4 cannot be identified and their names are nomina dubia. Here, I draw attention to the fact that, if the names are re-aligned to the images in a meaningful way, then at least three spiders on plate 4 can be identified. Theridion rufipes sensu Hahn is a synonym of Gongylidium rufipes (Linnaeus, 1758 (syn. conf.. In particular, the previous nomen dubium Theridion tibiale Hahn, 1831 is a senior synonym of Lasaeola tristis (Hahn, 1833 (syn. nov.. Evidence is presented that the junior synonym is in prevailing usage and the senior synonym is therefore regarded as nomen oblitum.

    Abstract The Neotropical genus Menevia Schaus, 1928 is revised to include 18 species, 11 of which are new. Two species, Menevia ostia comb. n. and Menevia parostia comb. n. are transferred from Pamea Walker, 1855 to Menevia. Four species-groups are diagnosed for the first time based on external characters and male genitalia morphology. The following new species are described: Menevia rosea sp. n., Menevia torvamessoria sp. n., Menevia magna sp. n., Menevia menapia sp. n., Menevia mielkei sp. n., Menevia australis sp. n., Menevia vulgaris sp. n., Menevia franclemonti sp. n., Menevia vulgaricula sp. n., Menevia cordillera sp. n., and Menevia delphinus sp. n.. A neotype is designated for Mimallo plagiata Walker, 1855, which has since been placed in Menevia. Mimallo saturata Walker, 1855 is interpreted to be a nomen dubium. PMID:27047245

The most interesting findings were threatened weed species growing in decontamination patches on loamy and nutrient-poor soils in the central part of the landfill. Dianthus armeria (C4a and Filago arvensis (C3 are listed in the national Red List of the Czech Republic. Moreover, these taxa were evaluated in the same category of rarity on the regional level. Apart from the above mentioned, Centaurea cyanus (C4a and Papaver dubium (C4a, registered only in the regional Red List of vascular plants of the Moravian-Silesian Region (see methods, were found. Besides threatened species, relatively small populations of invasive taxa as Erigeron annuus, Impatiens parviflora or Reynoutria sp., were also recorded on the landfill Supíkovice.

    The Colombian species of the genus Rhamma Johnson, 1992 are revised. Male and female phenotypes of all species are associated and diagnosed, and data on their distributions are given along with a discussion of the geographic variability of the species. Thirteen taxa are considered valid at the species level. The following taxonomic changes are proposed: Rhamma andradei (Le Crom & Johnson), stat. nov, comb. nov.; previously considered a nomen dubium in Penaincisalia Johnson, the taxon is considered a valid species of Rhamma. The placement of Rhamma anosma (Draudt), comb. nov., described as Thecla, is confirmed as belonging to Rhamma. A lectotype is designated for Thecla mishma Hewitson, 1878. Adults, male and female genitalia, and distribution maps are depicted for all species, along with an identification key based on adults.

    Full Text Available O objetivo deste trabalho foi avaliar a influência de tratamentos de superação da dormência de sementes sobre a taxa e o tempo de emergência de espécies arbóreas de Fabaceae, e sobre seu estabelecimento, quando reintroduzidas em pastagem, no Cerrado. Foram realizados experimentos em casa de vegetação e em campo (pastagem de Urochloa brizantha, com as espécies Mimosa caesalpiniifolia, Peltophorum dubium, Pterogyne nitens, Dimorphandra mollis, Copaifera langsdorffii e Hymenaea stigonocarpa, submetidas ou não aos seguintes tratamentos de superação de dormência: D. mollis e H. stigonocarpa, escarificação mecânica; C. langsdorffii e M. caesalpiniifolia, escarificação química com H2SO4; P. nitens, punção do tegumento; e P. dubium, imersão em água a 80ºC. O estabelecimento em campo foi monitorado por 21 meses. A superação de dormência promoveu, em casa de vegetação, maior emergência de quatro das seis espécies avaliadas, e, no campo, de cinco espécies. Além disso, reduziu o tempo de emergência das espécies e aumentou o recrutamento de M. caesalpiniifolia, P. nitens, D. mollis e H. stigonocarpa, aos 127 dias, e de H. stigonocarpa aos 659 dias. Os tratamentos de superação de dormência podem aumentar a eficiência da semeadura direta, em projetos de restauração de áreas degradadas no Cerrado, ao promover maior emergência das sementes e o estabelecimento das plantas.The objective of this work was to evaluate the influence of seed dormancy overcoming treatments on the rate and time of emergence of Fabaceae tree species, and on their recruitment when reintroduced in a tropical pasture, in the Brazilian Cerrado.

    Full Text Available Background Late adulthood is a period in which the number of stressors is increasing; therefore, strategies of coping with these situations may be significant in terms of the subjective evaluation of the quality of life and adaptation to old age. The objective of this paper was to examine the relationships between proactive coping and the quality of life in people in late adulthood. The quality of life was assessed using the Polish version of the CASP-19. Participants and procedure The research included 88 individuals (76 women and 12 men, aged from 60 to 85 years (M = 69.5, SD = 6.74. The following tools were used: The Proactive Coping Inventory, developed by Greenglass, Schwarzer and Taubert (Pasikowski’s adaptation, and the scale for the assessment of the quality of life, called CASP-19, of Higgs, Hyde, Wiggins and Blane (developed by the authors of this paper. Results The results of the research showed a positive relationship between the general level of proactive coping strategies, the proactive coping subscale and the general quality of life and addressing the needs of control and pleasure. People who are more proactive accomplish a higher general level of the quality of life, control and pleasure than people whose pro-activity level is lower. Conclusions Factors contributing to the quality of life and successful aging of elderly subjects are, first and foremost, skills connected with setting objectives autonomously, taking initiative, perseverance in activities and perceiving events in terms of opportunities of development and self-improvement. The CASP-19 seems to be a useful measure of the quality of life in old age.

Os métodos estudados foram: mudas distribuídas ao acaso em espaçamento de 2 x 2 m; mudas distribuídas individualmente ao acaso; mudas distribuídas ao acaso em agrupamento três a três, com espaçamento de 1 a 1,5 m. O crescimento da estatura e do diâmetro das espécies estudadas está diretamente relacionado com os períodos em estudo, o tratamento de recomposição e as espécies. O tratamento mudas distribuídas ao acaso individualmente foi o que apresentou melhor crescimento médio do diâmetro.This trial aimed at evaluating three methods to distribute seedlingsfrom Schinus terbinthifolia and Peltophorum dubium species for rearrangement of ciliary forests. Their growth changes in height and diameter were used as parameters during six terms in one year. The studied methods were: seedlings randomized distributed in 2 x 2 m; seedlings individually distributed in a randomized design and seedlings randomized distributed in groups by three, using a 1 to 1.5 m row distance. The growth regarding diameter and height of the observed species is straightly related to the studied periods, rearrangement treatment and species. As a conclusion, it was registered that the seedling treatment individually distributed in a randomized design was the best answer regarding the average growth ofdiameter.

    Traditional models hold that the plastic reorganization of brain structures occurs mainly during childhood and adolescence, leaving adults with limited means to learn new knowledge and skills. Research within the last decade has begun to overturn this belief, documenting changes in the brain's gray and white matter as healthy adults learn simple motor and cognitive skills [Lövdén, M., Bodammer, N. C., Kühn, S., Kaufmann, J., Schütze, H., Tempelmann, C., et al. Experience-dependent plasticity of white-matter microstructure extends into old age.

Although the significance of these changes is not fully understood, they reveal a brain that remains plastic well beyond early developmental periods. Here we investigate the role of adult structural plasticity in the complex, long-term learning process of foreign language acquisition. We collected monthly diffusion tensor imaging scans of 11 English speakers who took a 9-month intensive course in written and spoken Modern Standard Chinese as well as from 16 control participants who did not study a language. We show that white matter reorganizes progressively across multiple sites as adults study a new language. Language learners exhibited progressive changes in white matter tracts associated with traditional left hemisphere language areas and their right hemisphere analogs. Surprisingly, the most significant changes

    Full Text Available Two endomychid species described from El Hierro (Canary Islands are removed from the Canarian fauna: Dapsa hierrensis Franz, 1976 is a synonym of Archipines intricata (Gorham, 1889, nov. syn., and the single specimen (holotype was probably collected in Central America. Dapsa curta Franz, 1976 is also poorly described and based on a single female. Without a male it is not possible to assess with full confidence if it belongs to the African genus Danae or more probably to the Oriental genus Tragoscelis, and to which species. It is for sure not a Dapsa and its Canarian origin relates probably to another labeling error of the author, who also collected in Borneo, where this latter genus is present with 5 species. Consequently, Dapsa curta Franz, 1996 is proposed as nomen dubium. Furthermore, three genera are recorded for the Canaries for the first time: Silpha puncticollis Lucas, 1854 (Silphidae, the coffee bean borer Araecerus fasciculatus (DeGeer, 1775, and Bruchela rufipes (Olivier, 1790 both Anthribidae. Only the latter species can be considered as native; the other two are introduced recently and the Coffee bean weevil could become a pest.Dos especies de endomíquidos descritos de El Hierro (islas Canarias se eliminan de la fauna canaria: Dapsa hierrensis Franz, 1976 es una sinonimia posterior de Archipines intricata (Gorham, 1889, nov. syn., y el único ejemplar conocido (holotipo fue colectado probablemente en América Central.

    Full Text Available Diabetes is known as a multifactorial disease. The treatment of diabetes (Type II is complicated due to the inherent patho-physiological factors related to this disease. One of the complications of diabetes is post-prandial hyperglycemia (PPHG. Glucosidase inhibitors, particularly α-amylase inhibitors are a class of compounds that helps in managing PPHG. Six ethno-botanically known plants having antidiabetic property namely, Azadirachta indica Adr. Juss.; Murraya koenigii (L. Sprengel; Ocimum tenuflorum (L. (syn: Sanctum; Syzygium cumini (L. Skeels (syn: Eugenia jambolana; Linum usitatissimum (L. and Bougainvillea spectabilis were tested for their ability to inhibit glucosidase activity. The chloroform, methanol and aqueous extracts were prepared sequentially from either leaves or seeds of these plants. It was observed that the chloroform extract of O. tenuflorum; B. spectabilis; M. koenigii and S. cumini have significant α-amylase inhibitory property. Plants extracts were further tested against murine pancreatic, liver and small intestinal crude enzyme preparations for glucosidase inhibitory activity. The three extracts of O. tenuflorum and chloroform extract of M. koenigi showed good inhibition of murine pancreatic and intestinal glucosidases as compared with acarbose, a known glucosidase inhibitor.

    Full Text Available Background. Senna italica Miller or Cassia italica (Miller Sprengel is a native medicinal plant growing in south of Iran and has laxative and cathartic effects. Anthraquinone compounds have been partly associated with the purgative effects of the plant. One of the side effects of anthraquinones is griping and presence of flavonoid compounds in the plant may decrease this effect. Methods. In this study, the plant after being collected, was extracted by a soxhlet method. The isolation of flavonoids was carried out by means of preparative Thin Layer Chromatography of extract of the plant leaves. The structure of flavonoids was determined by the UV-Vis. techniques in methanol and by addition of the shift reagents and hydrolysis. The quantitative determinations of flavonoids in plant were also performed using an UV-Vis. spectroscopy method. Results and Discussion. Rutin or 5, 7, 3', 4' tetrahydroxy-flavone 3-O-rhamnoglucoside and two flavonoids from aurone group were isolated and identified from the leaves of Senna italica. The percent of flavonoids in Iranian Senna determined 1.5 fold than Cassia angustifolia. These flavonoids may decrease the griping effects of Senna anthraquinones

    Lycorine, the most frequent alkaloid found in Amaryllidaceae plants, has been proven to have various biological activities. Therefore, it is important to quantify this compound in Amaryllidacaeae species. In this study, a reversed-phase high-performance liquid chromatographic method has been used and validated for the determination of lycorine in Amaryllidaceae plants. A simple method for the extraction of lycorine in low-mass plant samples was employed utilizing columns pre-packed with diatomaceous earth (Extrelut). This method was applied to the aerial parts and bulbs of Sternbergia sicula Tineo ex Guss., S. lutea (L.) Ker-Gawl. ex Sprengel and Pancratium maritimum L. (Amaryllidaceae) collected during two different vegetation periods. The chromatographic separation was performed using an isocratic system with a mobile phase of trifluoroacetic acid-water-acetonitrile (0.01:90:10) applied at a flow rate 1 mL min(-1) using diode array detector. Validation procedures showed that the method was specific, accurate and precise. The amount of lycorine in S. sicula samples ranged between 0.10-0.53%, whereas in those of S. lutea and P. maritimum, the range was 0.19-0.40% and 0.05-0.14%, respectively.

    The ideal airway management modality in pediatric patients with syndromes like Klippel-Feil syndrome is a great challenge and is technically difficult for an anesthesiologist. Half of the patients present with the classic triad of short neck, low hairline, and fusion of cervical vertebra. Numerous associated anomalies like scoliosis or kyphosis, cleft palate, respiratory problems, deafness, genitourinary abnormalities, Sprengel's deformity (wherein the scapulae ride high on the back), synkinesia, cervical ribs, and congenital heart diseases may further add to the difficulty. Fiberoptic bronchoscopy alone can be technically difficult and patient cooperation also becomes very important, which is difficult in pediatric patients. Fiberoptic bronchoscopy with the aid of supraglottic airway devices is a viable alternative in the management of difficult airway in children. We report a case of Klippel-Feil syndrome in an 18-month-old girl posted for cleft palate surgery. Imaging of spine revealed complete fusion of the cervical vertebrae with hypoplastic C3 and C6 vertebrae and thoracic kyphosis. We successfully managed airway in this patient by fiberoptic intubation through classic laryngeal mask airway (LMA). After intubation, we used second smaller endotracheal tube (ETT) to stabilize and elongate the first ETT while removing the LMA. PMID:25191201

    Age-dependent tissue decline and increased cancer incidence are widely accepted to be rate-limited by the accumulation of somatic mutations over time. Current models of carcinogenesis are dominated by the assumption that oncogenic mutations have defined advantageous fitness effects on recipient stem and progenitor cells, promoting and rate-limiting somatic evolution. However, this assumption is markedly discrepant with evolutionary theory, whereby fitness is a dynamic property of a phenotype imposed upon and widely modulated by environment. We computationally modeled dynamic microenvironment-dependent fitness alterations in hematopoietic stem cells (HSC) within the Sprengel-Liebig system known to govern evolution at the population level. Our model for the first time integrates real data on age-dependent dynamics of HSC division rates, pool size, and accumulation of genetic changes and demonstrates that somatic evolution is not rate-limited by the occurrence of mutations, but instead results from aged microenvironment-driven alterations in the selective/fitness value of previously accumulated genetic changes. Our results are also consistent with evolutionary models of aging and thus oppose both somatic mutation-centric paradigms of carcinogenesis and tissue functional decline. In total, we demonstrate that aging directly promotes HSC fitness decline and somatic evolution via non-cell-autonomous mechanisms.

    The common bearberry (Arctostaphylos uva-ursi L. Sprengel) is a ubiquitous procumbent evergreen shrub located throughout North America, Asia, and Europe. The fruits are almost tasteless but the plant contains a high concentration of active ingredients. The antioxidant activity of bearberry leaf extract in the 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation assay was 90.42 mmol Trolox equivalents/g dry weight (DW). The scavenging ability of the methanol extract of bearberry leaves against methoxy radicals generated in the Fenton reaction was measured via electron paramagnetic resonance. Lipid oxidation was retarded in an oil-water emulsion by adding 1 g/kg lyophilised bearberry leaf extract. Also, 1 g/kg of lyophilised bearberry leaf extract incorporated into a gelatin-based film displayed high antioxidant activity to retard the degradation of lipids in muscle foods. The present results indicate the potential of bearberry leaf extract for use as a natural food antioxidant.

    Odonate larvae can be serious pests that attack fish larvae, postlarvae, and fingerlings in fish culture tanks, causing significant loss in the supply and production of juveniles. This study reports a screen of the essential oils (EOs) of Nectandra megapotamica (Sprengel) Mez, Nectandra grandiflora Nees, Hesperozygis ringens (Bentham) Epling, Ocimum gratissimum L., Aloysia gratissima (Gillies & Hooker) Troncoso, and Lippia sidoides Chamisso against Coenagrionidae larvae. In addition, the most effective EO and its 50% lethal concentration (LC50) and chemical analysis are described. The larvae of Acanthagrion Selys, Homeoura Kennedy, Ischnura Charpentier, and Oxyagrion Selys were used to assess the EO effects. EO obtained from H. ringens, O. gratissimum, and L. sidoides showed the highest larvicidal effects at 19 h of treatment. The major constituents of the EO of H. ringens include pulegone and limonene, while eugenol and Z-beta-ocimene predominate in the EO of O. gratissimum, and carvacrol and rho-cymene were the major compounds of the EO of L. sidoides. Leaf EOs from H. ringens, O. gratissimum, and L. sidoides showed activity against Coenagrionidae larvae at similar concentrations with LC50s of 62.92, 75.05, and 51.65 microl liter(-1), respectively, and these were considered the most promising treatments.

    Pennazio, Sergio

    2012-01-01

    The evolution of the concept of humus was in large part dependent on the development of the modern agriculture. This concept derived from the very old practice of manuring and, after a long period of empirical application, was first theorised by Albrecht Thaer, who recognised the organic and inorganic content as the nutritional elements of humus. The role of humus as nutrient was challenged by Carl Sprengel and Justus Liebig, who opposed successfully the mineral theory to the theory of humus. The research in the property of humus, however, continued thanks to agronomists and agricultural chemists during a period in which the mineral theory was consolidated by the first experiments of the hydroponic cultures performed by Julius Sachs and Wilhelm Knop, but several outstanding chemists and microbiologists continued the work initiated by Thaer, giving humus full physicochemical identity and function. In this context shone the figure of Selman Abraham Waksman, whose work was of fundamental importance to the subsequent research in humus, which is still in progress.

    Full Text Available Species identification and their market value and price evolution since the colonization time of the remnants of the Brazilian Semi-Evergreen Forest (Floresta Estacional Decidual do Rio Uruguai for potential timber production was assessed through 41 questionnaires, applied to timbermen and settlers from the surrounding region. The diversity of species for timber production commonly known by the people reached 63. From the 15 predominant species is relevant to mention Apuleia leiocarpa, Parapiptadenia rigida, Balfourodendron riedelianum, Nectandra megapotamica, Patagonula americana, Luehea divaricata, Cedrela fissilis, Ocotea diospyrifolia, Holocalyx balansae, Myrocarpus frondosus, Cabralea canjerana and Peltophorum dubium. The species with the highest commercial value were: Cordia trichotoma, Cedrela fissilis, Myrocarpus frondosus and Balfourodendron riedelianum. Data from the interviews suggest that several species from the Lauraceae family and Schefflera morototoni, Aralia warmingiana, Machaerium stipitatum, Chrysophyllum marginatum had an increment in use and commercial value during the last 15 years. Changing in the commercial value of a species was pointed out as due not only to the timber quality but also to the amount of the timber availability. Overall, it was detected that the species values changed across time and that the timber industry found several ways to adapt to the demands of forest products.

    The stable isotope compositions of moss tissue water (δ(2)H and δ(18)O) and cellulose (δ(13)C and δ(18)O), and testate amoebae populations were sampled from 61 contemporary surface samples along a 600-km latitudinal gradient of the Antarctic Peninsula (AP) to provide a spatial record of environmental change. The isotopic composition of moss tissue water represented an annually integrated precipitation signal with the expected isotopic depletion with increasing latitude. There was a weak, but significant, relationship between cellulose δ(18)O and latitude, with predicted source water inputs isotopically enriched compared to measured precipitation. Cellulose δ(13)C values were dependent on moss species and water content, and may reflect site exposure to strong winds. Testate amoebae assemblages were characterised by low concentrations and taxonomic diversity, with Corythion dubium and Microcorycia radiata types the most cosmopolitan taxa. The similarity between the intra- and inter-site ranges measured in all proxies suggests that microclimate and micro-topographical conditions around the moss surface were important determinants of proxy values. Isotope and testate amoebae analyses have proven value as palaeoclimatic, temporal proxies of climate change, whereas this study demonstrates that variations in isotopic and amoeboid proxies between microsites can be beyond the bounds of the current spatial variability in AP climate.

    2011-06-01

    Computed tomography (CT) methods were applied to a problematic fossil spider (Arachnida: Araneae) from the historical Berendt collection of Eocene (ca. 44-49 Ma) Baltic amber. The original specimens of Ocypete crassipes Koch and Berendt 1854 are in dark, oxidised amber and the published descriptions lack detail. Despite this, they were subsequently assigned to the living Pantropical genus Heteropoda Latreille, 1804 and are ostensibly the oldest records of huntsman spiders (Sparassidae) in general. Given their normally large size, and presumptive ability to free themselves more easily from resin, it would be surprising to find a sparassid in amber and traditional (optical) methods of study would likely have left O. crassipes as an equivocal record—probably a nomen dubium. However, phase contrast enhanced X-ray CT revealed exquisite morphological detail and thus `saved' this historical name by revealing characters which confirm that it's a bona fide member both of Sparassidae and the subfamily Eusparassinae. We demonstrate here that CT studies facilitate taxonomic equivalence even between recent spiders and unpromising fossils described in older monographs. In our case, fine structural details such as eye arrangement, cheliceral dentition, and leg characters like a trilobate membrane, spination and claws, allow a precise referral of this fossil to an extant genus as Eusparassus crassipes (Koch and Berendt 1854) comb. nov.

    Abstract The Assassin Spiders of the family Archaeidae from southern Australia are revised, with a new genus (Zephyrarchaea gen. n.) and nine new species described from temperate, mesic habitats in southern Victoria, South Australia and south-western Western Australia: Zephyrarchaea austini sp. n., Zephyrarchaea barrettae sp. n., Zephyrarchaea grayi sp. n., Zephyrarchaea janineae sp. n., Zephyrarchaea marae sp. n., Zephyrarchaea marki sp. n., Zephyrarchaea melindae sp. n., Zephyrarchaea porchi sp. n. and Zephyrarchaea vichickmani sp. n. Specimens of the type species, Zephyrarchaea mainae (Platnick, 1991), comb. n., are redescribed from the Albany region of Western Australia, along with the holotype female of Zephyrarchaea robinsi (Harvey, 2002) comb. n. from the Stirling Range National Park. The previously described species Archaea hickmani Butler, 1929 from Victoria is here recognised as a nomen dubium. A key to species and multi-locus molecular phylogeny complement the species-level taxonomy, with maps, habitat photos, natural history information and conservation assessments provided for all species.

    Nine species of Xylaria were collected in Taiwan from nests of Odontotermes formosanus, the only known macrotermitine termite in Taiwan. These include six newly described species, X. acuminatilongissima, X. atrodivaricata, X. brunneovinosa, X. griseosepiacea, X. intraflava and X. ochraceostroma, and three previously known species, X. cirrata, X. escharoidea and X. nigripes. We obtained cultures and ITS sequences from the nine species found in Taiwan and describe anamorphs for eight of them. Before the current study teleomorph-anamorph connections in the Xylaria species associated with termite nests have been established unequivocally in X. escharoidea only. Xylaria angulosa, X. fimbriata, X. kedahae, X. micrura, X. radicans, X. reinkingii and X. tolosa also are considered and annotated because they were reported to grow on ground and likely are associated with termite nests. Epitypifications are made for X. cirrata, X. escharoidea and X. nigripes. Xylaria sanchezii is considered a nomen dubium. Photographs are presented for most of the aforementioned species. A dichotomous key to 25 Xylaria species growing on termite nests or ground also is given.

    2011-10-01

    Sterol compositions for three diatom species, recently shown to contain sterols with side chains typically found in dinoflagellates, were determined by HPLC and ¹H NMR spectroscopic analyses. The centric diatom Triceratium dubium (=Biddulphia sp., CCMP 147) contained the highest percentage of 23-methylated sterols (37.2% (24R)-23-methylergosta-5,22-dienol), whereas the pennate diatom Delphineis sp. (CCMP 1095) contained the cyclopropyl sterol gorgosterol, as well as the 27-norsterol occelasterol. The sterol composition of Ditylum brightwellii (CCMP 358) was the most complex, containing Δ⁰- and Δ⁷-sterols, in addition to the predominant Δ⁵-sterols. A pair of previously unknown sterols, stigmasta-5,24,28-trienol and stigmasta-24,28-dienol, were detected in D. brightwellii and their structures were determined by NMR spectroscopic analysis and by synthesis of the former sterol from saringosterol. Also detected in D. brightwellii was the previously unknown 23-methylcholesta-7,22-dienol. Copyright © 2011 Elsevier Ltd. All rights reserved.

Two species, Conicera similis and Megaselia scalaris, are recorded in association with the summer truffle Tuber aestivum commercially grown in northern Israel. The status of the Afrotropical Phora congolensis Beyer, 1965 is designated as nomen dubium. A lapsius calami, which led to an erroneous generic attribution of Metopina braueri in the paper on Israeli Metopina (Mostovski, 2016), is noted here. An identification key to the Israeli genera of scuttle flies, as well as notes on recognition and/or biology of individual species, are provided.

  6. Systematic revision of the Potamotrygon motoro (Müller & Henle, 1841 species complex in the Paraná-Paraguay basin, with description of two new ocellated species (Chondrichthyes: Myliobatiformes: Potamotrygonidae

    Full Text Available A systematic revision of the Potamotrygon motoro (Müller & Henle, 1841 species complex in the Paraná-Paraguay basin based on morphological characters was undertaken. Morphological systems analyzed include external morphology, coloration, dermal denticles, and spines, canals of the ventral lateral-line system, and skeletal components. Potamotrygon motoro is widely distributed in the Paraná-Paraguay basin and some of its diagnostic characters are: ocelli present on dorsal disc tricolored, well-defined and evenly distributed, with diameter similar or greater than eye-length; ventral coloration with relatively large whitish central region, with gray or brown area predominant on outer ventral disc margins; dermal denticles well-developed and star-shaped over central disc; labial grooves absent; monognathic heterodonty present in upper and lower jaws of adults. Potamotrygon pauckei Castex, 1963 and Potamotrygon labradori Castex, Maciel & Achenbach, 1963, are synonymized with P. motoro; Potamotrygon alba Castex, 1963, is a nomen dubium in accordance with previous authors. Additionally, two new ocellated species of Potamotrygon from the Paraná-Paraguay basin are described: Potamotrygon pantanensis, sp. nov. and Potamotrygon amandae, sp. nov. These are described and compared with P. motoro and other congeners. Potamotrygon pantanensis, sp. nov. is described from the northern Pantanal region; Potamotrygon amandae, sp. nov. is widespread in the Paraná-Paraguay basin.

    We dedicate this article to the memory of Sergio de Freitas, FCAV-UNESP, Jaboticabal, São Paulo, Brazil (deceased, 2012). He was an active and enthusiastic Neuropterist and the cherished mentor and friend of Francisco Sosa. Leucochrysa McLachlan is the largest genus in the Chrysopidae, yet it has received relatively little taxonomic attention. We treat two problematic and common Leucochrysa species - Leucochrysa (Leucochrysa) varia (Schneider, 1851) and Leucochrysa (Leucochrysa) pretiosa (Banks, 1910). Both are highly variable in coloration and were described before the systematic importance of chrysopid genitalia was recognized. Recent studies show that these species occur within a large complex of cryptic species and that they have accumulated a number of taxonomic problems. We identify new synonymies for each of the species-for Leucochrysa (Leucochrysa) varia: Leucochrysa (Leucochrysa) ampla (Walker, 1853), Leucochrysa internata (Walker, 1853), and Leucochrysa (Leucochrysa) walkerina Navás, 1913; for Leucochrysa (Leucochrysa) pretiosa: Leucochrysa (Leucochrysa) erminea Banks, 1946. The synonymy of Leucochrysa delicata Navás, 1925 with Leucochrysa (Leucochrysa) pretiosa is stabilized by the designation of a neotype. The following species, which were previously synonymized with Leucochrysa (Leucochrysa) varia or Leucochrysa (Leucochrysa) pretiosa, are reinstated as valid: Leucochrysa (Leucochrysa) phaeocephala Navás, 1929, Leucochrysa (Leucochrysa) angrandi (Navás, 1911), and Leucochrysa (Leucochrysa) variata (Navás, 1913). To help stabilize Leucochrysa taxonomy, lectotypes are designated for Allochrysa pretiosa and Allochrysa variata. Finally, Leucochrysa vegana Navás, 1917 is considered a nomen dubium.

    Full Text Available During the program “Environmental Characterization of the Campos Basin, RJ, Brazil”, from 2001 to 2003, samples were taken of soft bottoms from the continental slope of Campos Basin (off southeast Brazil by the Research Vessel “Astro-Garoupa” with a 0.25 m2 box corer or by dredging with a Charcot dredge; 117 stations with depths from 700 to 1950 m were sampled. There were molluscs in all samples, and among Gastropoda the Turridae showed the highest diversity. Here we present the results obtained for the subfamilies Mangeliinae, Taraninae and Clathurellinae. Two species were found within Mangeliinae: Benthomangelia cf. macra (Watson, 1881 and Benthomangelia enceladus n. sp. Within Taraninae only one undescribed species was found: Taranis tanata n. sp. Within Clathurellinae we found four species: Corinnaeturris leucomata (Dall, 1881, recorded for the first time in the South Atlantic; Corinnaeturris rhysa (Watson, 1881, extending its described depth range; Corinnaeturris angularis n. sp., Typhlomangelia nivalis (Lovén, 1846, expanding its known distribution farther south; and Drilliola pulchella (Verrill, 1880. The type material of Drilliola loprestiana (Calcara, 1841, previously considered lost, has been located and is illustrated here. Drilliola crispata (Cristofori and Jan, 1832 is considered to be a nomen dubium.

    Ten species of Macrostomorpha were found in marine environments of the Algarve (Portugal). Six of them were found in the Ria Formosa, a vast intertidal euryhaline lagoon system that dominates the most Eastern coast of the Algarve: two unidentified species of Microstomum Schmidt, 1848, Macrostomum cf. rubrocinctum Ax, 1951 and two unidentified species of Macrostomum Schmidt, 1848, Paromalostomum dubium (de Beauchamps, 1927), Paromalostomum minutum Rieger, 1971 and Cylindromacrostomum faroensis n.sp.. Comparison of this species with C. mediterraneum (Ax, 1955) and the species from Venice, considered to be C. mediterraneum by Rieger (1977), leads to the conclusion that the individuals studied by Rieger are in fact representatives of a separate species, C. riegeri n.sp.. Acanthomacrostomum spiculiferum Papi & Swedmark, 1959 was found in the Atlantic, 10-15 m deep, near the western coast of the Algarve. Haplopharynx papii n. sp. occurs on the beach exposed to the Atlantic as well as in the Ria Formosa. All identified and previously known (marine) species found in the Algarve had been found before, either in the Atlantic or in the Mediterranean basin.

    The evolution of the avian brain is of crucial importance to studies of the transition from non-avian dinosaurs to modern birds, but very few avian fossils provide information on brain morphological development during the Mesozoic. An isolated specimen from the Cenomanian of Melovatka in Russia was described by Kurochkin and others as a fossilized brain, designated the holotype of Cerebavis cenomanica Kurochkin and Saveliev and tentatively referred to Enantiornithes. We have previously highlighted that this specimen is an incomplete skull, rendering the diagnostic characters invalid and Cerebavis cenomanica a nomen dubium. We provide here a revised diagnosis of Cerebavis cenomanica based on osteological characters, and a reconstruction of the endocranial morphology (= brain shape) based on μCT investigation of the braincase. Absence of temporal fenestrae indicates an ornithurine affinity for Cerebavis. The brain of this taxon was clearly closer to that of modern birds than to Archaeopteryx and does not represent a divergent evolutionary pathway as originally concluded by Kurochkin and others. No telencephalic wulst is present, suggesting that this advanced avian neurological feature was not recognizably developed 93 million years ago. © 2015 Anatomical Society.

    Full Text Available A new species of Enna O. Pickard-Cambridge, 1897 from Cusco, Peru and two new species of Caricelea SILVA & LISE, 2007 based in males collected in Cusco, Peru are described. Enna echarate sp. nov. can be distinguished from other species by the two lateral excavations on the epigynal middle field. Caricelea apurimac sp. nov. an be distinguished from the other members of the genus, by the larger lamellar projection (LP on the median apophysis that covers most of the guide. Caricelea camisea sp. nov. can be distinguished from other species of the genus, by the smaller lamellar projection and the smaller and acute ental division of the retrolateral apophysis. The males of Hesydrus caripito Carico, 2005 and Syntrechalea reimoseri (Caporiacco, 1947 are described and illustrated for the first time. Trechalea numida Mello-Leitão, 1943 and Trechalea limai Mello-Leitão, 1941 are transferred to Thaumasia Perty, 1833 (Pisauridae and Paratrechalea Carico, 2005 (Trechaleidae as species inquirenda and nomen dubium, respectively.

    Full Text Available The taxonomic composition and systematic position of Agriopodes Hampson is examined through an integrated approach using adult and larval morphology, biology, and molecular sequence data. The type-species of Agriopodes, Moma fallax Herrich-Schäffer is shown to be derived within the Acronicta grisea Walker species-group; accordingly, Agriopodes is relegated to synonymy under Acronicta Ochsenheimer, syn. n. (Acronictinae. Additionally, molecular markers and morphology show that Agriopodes is not monophyletic: Agriopodes tybo (Barnes is not closely related to A. fallax nor to Acronicta, and is transferred to a new genus, Chloronycta Schmidt & Anweiler, gen. n. The immature stages of Chloronycta tybo, comb.n. are described and illustrated for the first time. Although previously treated as a valid species, we show that Agriopodes geminata (Smith represents the northern terminus of clinal variation in wing pattern of A. fallax and synonymize A. geminata under A. fallax (syn. n.. The history and identity of Agriopodes corticosa (Boisduval, a nomen dubium, is discussed.

  13. Platystrophia (Orthida and new related Ordovician and Early Silurian brachiopod genera

    Harper, David A. T.

    2007-03-01

    Full Text Available More than 150 Ordovician and Early Silurian brachiopod species have been assigned to the genus Platystrophia King, 1850 mainly on the basis of their Spirifer-like shell exteriors. King’s concept of the genus was based on Platystrophia biforata King, which is not conspecific with Terebratulites biforatus Schlotheim, traditionally regarded as the type species of Platystrophia. Porambonites costatus Pander, 1830 is formally proposed as the type species of the genus to replace P. biforata; the latter is considered to be a nomen dubium. In our revised diagnosis, Platystrophia is restricted to a group of Arenig to upper Caradoc species from Baltica and Avalonia, whereas the Ashgill and lower Silurian taxa of these regions, hitherto assigned to Platystrophia, are placed in the new genus Neoplatystrophia. Platystrophia ponderosa Foerste, 1909 from the Upper Ordovician of North America is proposed as the type species of a new genus Vinlandostrophia. Two new species, Platystrophia baltica and Platystrophia pogrebovi from the Llanvirn–Caradoc of the East Baltic are also described.

  14. Nomina dubia and available names.

    1980-01-01

    The availability or non-availability of a name is a question of historical fact. A name once made available under the International Code of Zoological Nomenclature can be rendered unavailable only by use of the plenary powers of the Commission. The question whether a name is a nomen dubium or not is a matter of taxonomic judgement. The difficulty with the Sarcocystinae discussed by Frenkel et al. (1979) stems from the fact that, under the present provisions of the Code, it is not possible to designate for the species concerned types that will serve any useful function. The Commission is now considering changes to the Code proposed to remedy this defect in a general, legislative way. It will not, as a matter of general practice, entertain proposals for the suppression of names merely because they are considered to be nomina dubia. The application submitted by Professor Frenkel and his collegaues will nevertheless be published in the Bulletin of Zoological Nomenclature so that the Commission can, if necessary, deliver a ruling on it before the new edition of the Code has appeared.

    Examination of the original descriptions of the species of Sarcocystis in cattle, sheep, and swine, and of isosporid oocysts shed sporulated by dogs, cats, man, and other carnivores, has shown that it is not possible in most instances to identify unambiguously recently recognized taxa. The original descriptions are insufficient, and because no type specimens exist, could apply to two or more of the presently recognized taxa. We consider the following nomina dubia: Sarcocystis hirsuta S. miescheriana S. tenella S. cruzi S. bertrami Isospora bigemina (S. bigemina) I. hominis (S. hominis) I. buteonis (Frenkelia buteonis) Because the former type species, Sarcocystis miescheriana, is an indeterminate nomen dubium, we are proposing S. muris as the new type species. Historically, it was the first species described clearly and unambiguously even in the light of present knowledge, and the stages of its life cycle are probably completely known; it was the second species to be named. Old and recent descriptions are reviewed, and definitions are proposed for the following taxa: S. bovifelis S. bovicanis S. bovihominis S. ovifelis S. ovicanis S. muris (type species) S. suihominis S. suicanis S. equicanis Frenkelia microti F. glareoli for which neotypes will be prepared and deposited with designated institutions and curators. A new subfamily, Cystoisosporinae, is created.

  16. Revision of “Balaena” belgica reveals a new right whale species, the possible ancestry of the northern right whale, Eubalaena glacialis, and the ages of divergence for the living right whale species

    Full Text Available In 1941, Abel established Balaena belgica based on a series of fused cervical vertebrae and citing other cranial fragments from the late Neogene of the Antwerp harbor (northern Belgium. Later, Plisnier-Ladame & Quinet (1969 added a neurocranium and other skeletal remains from the same area to this species. Recently, the neurocranium was re-assigned to the genus Eubalaena thanks to newer phylogenetic analyses. Here, a new description is provided of materials previously assigned to “Balaena” belgica together with taxonomic revisions. Our work suggests that the cervical complex originally designated as the type of “Balaena” belgica is too poorly preserved to be used as such and is assigned to Balaenidae gen. et sp. indet., thus making “Balaena” belgica a nomen dubium. In addition to the neurocranium, the other remains consist in a fragment of maxilla assigned to Balaenidae gen. et sp. indet. and in a humerus assigned to Eubalaena sp. Discovered in the Kruisschans Sands Member of the Lillo Formation (3.2–2.8 Ma, Piacenzian, Late Pliocene, the neurocranium is designated as the holotype of the new species Eubalaena ianitrix. Our phylogenetic analysis supports a sister-group relationship of Eubalaena ianitrix and Eubalaena glacialis, and helps constraining the ages of origin for balaenid clades. Ecological and phylogenetic data suggest that Eubalaena ianitrix may represent the direct ancestor of Eubalaena glacialis, the latter having evolved through phyletic transformation including body size increase during the temperature decline of the Late Pliocene.

  17. Expression levels of antimicrobial peptide tachyplesin I in transgenic Ornithogalum lines affect the resistance to Pectobacterium infection.

    The genus Ornithogalum includes several ornamental species that suffer substantial losses from bacterial soft rot caused by Pectobacteria. The absence of effective control measures for use against soft rot bacteria led to the initiation of a project in which a small antimicrobial peptide from an Asian horseshoe crab, tachyplesin (tpnI), was introduced into two commercial cultivars: O. dubium and O. thyrsoides. Disease severity and bacterial colonization were examined in transgenic lines expressing this peptide. Disease resistance was evaluated in six lines of each species by measuring bacterial proliferation in the plant tissue. Three transgenic lines of each species were subjected to further analysis in which the expression level of the transgene was evaluated using RT-PCR and qRT-PCR. The development of disease symptoms and bacterial colonization of the plant tissue were also examined using GFP-expressing strain of P. carotovorum subsp. brasiliense Pcb3. Confocal-microscopy imaging revealed significantly reduced quantities of bacterial cells in the transgenic plant lines that had been challenged with the bacterium. The results clearly demonstrate that tpnI expression reduces bacterial proliferation, colonization and disease symptom (reduced by 95-100%) in the transgenic plant tissues. The quantity of tpnI transcripts, as measured by qRT-PCR, was negatively correlated with the protection afforded to the plants, as measured by the reduced severity of disease symptoms in the tissue.

Muitos estudos têm evidenciado mudanças nas características anatômicas e fisiológicas de plantas medicinais sob influência de condições de radiação. Neste trabalho analisou-se a influência de fotoperíodos (8; 12; 16 e 20 h na anatomia foliar, nos teores de clorofila e condutância estomática em três regiões da planta. Após 90 dias de tratamento, plantas adultas e com diferentes tamanhos influenciados pelos fotoperíodos foram submetidas às avaliações anatômicas e fisiológicas. Os teores de clorofila foram maiores nos fotoperíodos de 8 e 12 h nas regiões superior e mediana da planta e menores no fotoperíodo de 8 h na região basal. A condutância e densidade estomática apresentaram relação inversa ao aumento do fotoperíodo, sendo significativamente decrescente do ápice para a base da planta. Houve aumento da espessura da epiderme adaxial nas regiões mediana e basal da planta até o fotoperíodo de 16 h. Nestas regiões houve aumento progressivo do parênquima esponjoso até o fotoperíodo de 20 h. Verificou-se modificações no tamanho e organização dos feixes vasculares influenciadas pelos fotoperíodos.Guaco (Mikania glomerata Sprengel is a medicinal species known because of its bronchi-dilating activity.

  1. Ethnomedicine and ethnobotany of fright, a Caribbean culture-bound psychiatric syndrome

    2010-02-01

    Full Text Available Abstract Background "Fright" is an English-speaking Caribbean idiom for an illness, or ethnomedical syndrome, of persistent distress. A parallel ethnopsychiatric idiom exists in the French Antilles as sésisma. Fright is distinct from susto among Hispanics, though both develop in the wake of traumatic events. West Indian ethnophysiology (ethnoanatomy theorizes that an overload of stressful emotions (fear, panic, anguish or worry causes a cold humoral state in which blood coagulates causing prolonged distress and increased risks of other humorally cold illnesses. Methods Qualitative data on local explanatory models and treatment of fright were collected using participant-observation, informal key informant interviews and a village health survey. Ethnobotanical and epidemiological data come from freelist (or "free-list" tasks, analyzed for salience, with nearly all adults (N = 112 of an eastern village in Dominica, and a village survey on medicinal plant recognition and use (N = 106. Results Along with prayer and exercise, three herbs are salient fright treatments: Gossypium barbadense L., Lippia micromera Schauer, and, Plectranthus [Coleus] amboinicus [Loureiro] Sprengel. The survey indicated that 27% of village adults had medicated themselves for fright. Logistic regression of fright suffering onto demographic variables of age, education, gender, parental status and wealth measured in consumer goods found age to be the only significant predictor of having had fright. The probability of having (and medicating for fright thus increases with every year. Conclusions While sufferers are often uncomfortable recalling personal fright experiences, reporting use of medicinal plants is less problematic. Inquiry on fright medical ethnobotany (or phytotherapies serves as a proxy measurement for fright occurrence. Cross-cultural and ethnopharmacology literature on the medicinal plants suggests probable efficacy in accord with Dominican ethnomedical notions

    The deleterious effects of lipid autoxidation are of major concern to the food industry and can be prevented by food antioxidants. In this vein, the phenolic contents and antioxidant potential of traditional plants of Mauritius such as P. betle L. (Piperaceae), M. koenigii L. Sprengel. (Rutaceae), O. gratissimum L. (Lamiaceae), O. tenuiflorum L. (Lamiaceae), and commercially available Mauritian green and black teas were evaluated. Their ferric reducing antioxidant power (FRAP) were compared to that of butylated hydroxytoluene (BHT) with the following order of potency: BHT > "Natural" commercial green tea > "Black Label" commercial black tea > O. gratissimum > P. betle > O. tenuiflorum > M. koenigii. The trolox equivalent antioxidant capacity (TEAC) assay reflected a similar antioxidative order for BHT and "Natural" commercial green tea, with however P. betle, O. tenuiflorum and O. gratissimum exhibiting higher activities than "Black Label" commercial black tea and M. koenigii. Based on their potent antioxidant capacity, P. betle (0.2 % m/m) and O. tenuiflorum (0.2 % m/m) extracts, and green tea (0.1 % m/m) infusate were compared with BHT (0.02 % m/m) on their ability to retard lipid oxidation in unstripped sunflower oil and mayonnaise during storage at 40 °C. P. betle and green tea were more effective than BHT in both food systems. Moreover, odour evaluation by a sensory panel showed that the plant extracts and green tea infusate effectively delayed the development of rancid odours in unstripped sunflower oil and mayonnaise (p < 0.05).

    This retrospective study analyses 23 children treated with vertical expandable prosthetic titanium rib (VEPTR) for correction of non-congenital early onset spine deformities. After the index procedure (IP), the device was lengthened at 6-month intervals. The average (av) age at the time of IP was 6.5 years (1.11-10.5). The av follow-up time was 3.6 years (2-5.8). Diagnosis included 1 early onset idiopathic scoliosis, 11 neuromuscular, 2 post-thoracotomy scoliosis, 1 Sprengel deformity, 2 hyperkyphosis, 1 myopathy and 5 syndromic. Surgeries (187) included 23 IPs, av 6.5 (4-10) device expansions per patient (149) and 15 unplanned surgeries. 23 complications (0.13 per surgery) included 10 skin sloughs, 5 implant dislocations, 2 rod breakages and 6 infections. Coronal Cobb angle was av 68 degrees (11 degrees -111 degrees ), at follow-up av 54 degrees (0 degrees -105 degrees). Pelvic obliquity was av 33 degrees (13 degrees -60 degrees ), at follow-up av 16 degrees (0 degrees -42 degrees ). T1 tilt was av 29 degrees (5 degrees -84 degrees ), two remained unchanged, the remainder improved 10 degrees -68 degrees. Sagittal plane: All but two had stable profiles, two hyperkyphosis of 110 degrees /124 degrees improved to 56 degrees /86 degrees. Space available for lung ratio was less than 90% in ten before the IP, improved in nine and deteriorated in one. Originally designed for thoracic insufficiency syndromes related to rib and vertebral anomalies, VEPTR proved to be a valuable alternative to dual growing rods for non-congenital early onset spine deformities. The complication rate was lower, the control of the sagittal plane and the pelvic obliquity was as good, but the correction of the coronal plane deformity was less than growing rods. However, VEPTR's spine-sparing approach might provoke less spontaneous spinal fusion and ease the final correction at maturity.

    Carbazole alkaloids, a major constituent of Murraya koenigii (L.) Sprengel (Rutaceae), exhibit biological effects such as anticancer activity via the induction of apoptosis, and they represent candidate chemotherapeutic agents. Oral squamous cell carcinoma (OSCC) is the most prevalent cancer of the oral cavity and a growing and serious health problem worldwide. In this study, we investigated the anticancer properties and mechanisms of action of two carbazole alkaloids derived from M. koenigii leaves, mahanine and isomahanine, in the OSCC cell line CLS-354. At 15 μM, mahanine and isomahanine were cytotoxic to CLS-354 cells, triggering apoptosis via caspase-dependent and -independent mechanisms. Autophagosomes, visualised using monodansylcadaverine (MDC) labelling, were numerous in carbazole alkaloid-treated cells. Mahanine and isomahanine markedly induced the expression of the autophagosome marker microtubule-associated protein 1 light chain 3, type II (LC3B-II). Genetic and chemical inhibition of autophagy via silencing of the Autophagy protein 5 gene and exposure to bafilomycin A1 (BafA1), respectively, did not arrest carbazole alkaloid-induced apoptosis, indicating that it occurs independently of autophagic activation. Surprisingly, both carbazole alkaloids caused increased accumulation of p62/sequestosome1 (p62/SQSTM1), with coordinated expression of LC3B-II and cleaved caspase-3, suggesting inhibition of autophagic flux. Our results suggest that inhibition of autophagic flux is associated with carbazole alkaloid-induced apoptosis. Our findings provide evidence of a novel cytotoxic action of natural carbazole alkaloids and support their use as candidate chemotherapeutic agents for the treatment of OSCC.

    Environmental stress in plants impacts many biological processes, including male gametogenesis, and affects several cytological mechanisms that are strongly interrelated. To understand the likely impact of rising temperature on reproductive fitness in the climate change regime, a study of tapetal mitosis and its accompanying meiosis over seasons was made to elucidate the influence of temperature change on the cytological events occurring during microsporogenesis. For this we used two species of an environmentally sensitive plant system, i.e., genus Cymbopogon Sprengel (Poaceae), namely Cymbopogon nardus (L.) Rendle var. confertiflorus (Steud.) Bor (2n = 20) and Cymbopogon jwaruncusha (Jones) Schult. (2n = 20). Both species flower profusely during extreme summer (48 °C) and mild winter (15 °C) but support low and high seed fertility, respectively, in the two seasons. We have shown that tapetal mitotic patterns over seasons entail differential behavior for tapetal mitosis. During the process of tapetum development there are episodes of endomitosis that form either (i) an endopolyploid genomically imbalanced uninucleate and multinucleate tapetum, and (or) (ii) an acytokinetic multinucleate genomically balanced tapetum, with the progression of meiosis in the accompanying sporogenous tissue. The relative frequency of occurrence of the two types of tapetum mitosis patterns is significantly different in the two seasons, and it is found to be correlated with the temperature conditions. Whereas, the former (genomically imbalanced tapetum) are prevalent during the hot summer, the latter (genomically balanced tapetum) are frequent under optimal conditions. Such a differential behaviour in tapetal mitosis vis-à-vis temperature change is also correspondingly accompanied by substantial disturbances or regularity in meiotic anaphase disjunction. Both species show similar patterns. The study underpins that tapetal mitotic behaviour per se could be a reasonable indicator to

    The ancient Egyptian civilization lasted for over 3000 years and ended in 30 BCE. Many aspects of ancient Egyptian culture, including the existence of skeletal dysplasias, and in particular achondroplasia, are well known through the monuments and records that survived until modern times. The hot and dry climate in Egypt allowed for the preservation of bodies and skeletal anomalies. The oldest dwarf skeleton, the Badarian skeleton (4500 BCE), possibly represents an epiphyseal disorder. Among the remains of dwarfs with achondroplasia from ancient Egypt (2686-2190 BCE), exists a skeleton of a pregnant female, believed to have died during delivery with a baby's remains in situ. British museums have partial skeletons of dwarfs with achondroplasia, humeri probably affected with mucopolysaccharidoses, and a skeleton of a child with osteogenesis imperfecta. Skeletal dysplasia is also found among royal remains. The mummy of the pharaoh Siptah (1342-1197 BCE) shows a deformity of the left leg and foot. A mummified fetus, believed to be the daughter of king Tutankhamun, has scoliosis, spina bifida, and Sprengel deformity. In 2006 I reviewed the previously existing knowledge of dwarfism in ancient Egypt. The purpose of this second historical review is to add to that knowledge with an expanded contribution. The artistic documentation of people with skeletal dysplasia from ancient Egypt is plentiful including hundreds of amulets, statues, and drawing on tomb and temple walls. Examination of artistic reliefs provides a glance of the role of people with skeletal dysplasia and the societal attitudes toward them. Both artistic evidence and moral teachings in ancient Egypt reveal wide integration of individuals with disabilities into the society.

    Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), with the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%.

    Full Text Available Segetal flora of cereal crop agrocenoses in the Suwałki Landscape Park was studied in between the years 2012 and 2013. One hundred phytosociological Braun-Blanquet releves were taken, documenting the occurrence of 152 species of vascular plants that represented 29 botanic families. Analysis of the contributions of geographic-historical groups revealed the dominance of the native species, apophytes (87 species, making 57.2%, over anthropophytes (65 species, 42.8%. The number of short-lived species was twice greater (103 species, 67.8% than the perennial ones (49 species, 32.2%. As regards the lifeforms, the therophytes were dominant (96 species, 63.2% over hemicryptophytes (44 species, 28.9% and geophytes (12 species, 7.9%. Among the species of segetal flora in the area studied, 23 valuable species classified to different categories of protection, were identified. The presence of Consolida regalis, Centaurea cyanus and Bromus secalinus, belonging to threatened species in other regions of Poland, was abundant. Also the species: Anthemis tinctoria, Echium vulgare and Anchusa officinalis were met with high frequency. The species: Agrostemma githago, Papaver argemone and Papaver dubium were represented by single plants, which can suggest their dying out. In the Park area, expansive species, threatening the biodiversity, such as Myosotis arvensis, Viola arvensis, Galeopsis tetraehit, Stellaria media, Artemisia vulgaris, Galinsoga parviflora, Elymus repens, Capsella bursa pastoris, Erodium cicutarium, Chamomilla recutita, Matricaria maritima subsp. inodora, Convolvulus arvensis, Polygonum persicaria, Polygonum lapathifolium subsp. pallidum and Polygonum lapathifolium subsp. lapathifolium, were commonly seen in the crop land.

  16. Catholic options in the abortion debate.

    Maguire, D C

    1990-01-01

    The little-known Roman Catholic theological doctrine of probabilism, an ethical system explicated in all manuals of moral theology, is explained using as an example the dilemma of abortion. Probabilism is based on the notion that a doubtful moral obligation may not be imposed as though it were certain. "Ubi dubium, ibi libertas," means where there is doubt, there is freedom. There are 2 types of moral probability, intrinsic probability, where the individual, without the help of moral theologians, perceives the inapplicability of a particular moral teaching; and extrinsic probability, which involves reliance on the findings of 5 or 6 reputable moral theologians, who may hold a liberal view. Probabilism implies a reasonable doubt, and one's reasons must be cogent, but not necessarily conclusive. Today's abortion debate is an example of a respectable debate, where the liberal view has been endorsed by a number of reputable religious or other humanitarian bodies that in some cases abortion is not always immoral. Other examples in history are the view once taught by the church that taking interest on loans was immoral, that depriving slaves and women of civil rights on non-Catholics of religious or political freedom was moral. For today's legislators, there is a precedent throughout theological history for the state permitting an evil: both St. Augustine and St. Thomas Aquinas wrote that prostitution, although evil, should not be outlawed, because worse evils would occur with prohibition. Legislators who personally find abortion always immoral can support a Roe V. Wade decision because 1) it does not require anyone to have an abortion, and 2) the abortion debate, among Catholics, and non-Catholics is not settled.

    The characteristics and availability of the sleeping sites used by a group of 27 tufted capuchin monkeys (Cebus apella nigritus) were studied during 17 months at the Iguazu National Park, Argentina. We tested different hypotheses regarding possible ultimate causes of sleeping-site selection. Most sleeping sites were located in areas of tall, mature forest. Of the 34 sleeping sites the monkeys used during 203 nights, five were more frequently used than the others (more than 20 times each, constituting 67% of the nights). Four species of tree (Peltophorum dubium, Parapiptadenia rigida, Copaifera langsdorfii and Cordia trichotoma) were the most frequently used. They constituted 82% of all the trees used, though they represent only 12% of the trees within the monkeys' home range which had a diameter at breast height (DBH) > 48.16 cm (1 SD below the mean DBH of sleeping trees). The sleeping trees share a set of characteristics not found in other trees: they are tall emergent (mean height +/- SD = 31.1+/-5.2 m) with large DBH (78.5+/-30.3 cm), they have large crown diameter (14+/-5.5 m), and they have many horizontal branches and forks. Adult females usually slept with their kin and infants, while peripheral adult males sometimes slept alone in nearby trees. We reject parasite avoidance as an adaptive explanation for the pattern of sleeping site use. Our results and those from other studies suggest that predation avoidance is a predominant factor driving sleeping site preferences. The patterns of aggregation at night and the preference for trees with low probability of shedding branches suggest that social preferences and safety from falling during windy nights may also affect sleeping tree selection. The importance of other factors, such as seeking comfort and maintaining group cohesion, was not supported by our results. Other capuchin populations show different sleeping habits which can be explained by differences in forest structure and by demographic differences.

  5. The light bulb, cystoscopy, and Thomas Alva Edison.

    Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

É freqüentemente usada em programas de recomposição ou como árvore ornamental. Sua madeira oferece a possibilidade de múltiplos usos e é de longa durabilidade. O objetivo deste trabalho foi avaliar o potencial de armazenamento e a germinabilidade e vigor das sementes de canafístula em diferentes substratos e profundidades de semeadura. Após a escarificação, as sementes foram postas para germinar em papel, xaxim, areia e algodão. Não se observou diferença significativa entre os substratos com relação à porcentagem e velocidade de germinação. A viabilidade e o vigor não foram alterados após armazenamento em ambiente natural ou a 10oC e com o uso de embalagem de papel ou vidro com tampa plástica após 45 e 70 dias. As sementes de canafístula também se mostraram resistentes ao envelhecimento precoce (45oC e 100% de umidade relativa, com redução significativa do número de plântulas emergidas apenas a partir de 144 horas, mas sem redução significativa da biomassa seca.

    The objectives of this research were: to study the effect of different methods of site cleaning and soil preparation on the reforestation growths established with typical species of the Atlantic Forest; and to evaluate the efficiency of different methods of weed control from planting time to canopy closure. The trial was installed (from Feb to May 1995) around the reservoir of Mario Lopes Leao hydroelectric plant owned by the Electric Power of Sao Paulo (CESP), municipal district of Promissao, SP. The climate of the area is tropical with dry winter (Cwa, classification of Koeppen). The soil was characterized as an Red-Dark Latosol, medium texture. Six treatments arranged in a randomized block design with four replications were tested: 1) herbicide application over total area, planting in furrows (PF), manual weeding in the planting row (MWR) and herbicide application inter rows (HAI); 2) slashing in total area (STA), planting hole (Ph), MW R and slashing inter rows: 3) STA, slash burning (SB), heavy and light harrowing (HLH), PF, MWR and HAI; 4) STA, SB, PF, MWR and HAI; 5) STA, SB, PF, HLH, MWR and HAI; and 6) SAT, SB, two heavy harrowing, PH, selective weed control in the rows and inter rows. The plantation was accomplished with a composition of nine species: pioneers - Trema micrantha, Guazuma ulmifolia and Croton urucurana; secondary - Peltophorum dubium, Gallesia integrifolia and Ormosia arborea and climax - Tabebuia avellanedae, Hymenaea courbaril and Genipa americana. The pioneer and secondary species presented the highest results to the applied treatments. In all treatments where weed control was made with herbicide (glyphosate), the occurrence of Panicum maximum, common species in the area, was very restricted. The growth rates were intensified and the under story presented more diversified composition of weed species, with predominance of broad leaves. Opposite results were observed when weed controlled was manually or mechanically. The largest

    A new species, Isospora streperae n. sp., (Apicomplexa: Eimeriidae) is described from a single grey currawong bird (Strepera versicolour) (subspecies S. v. plumbea) in Western Australia. Sporulated oocysts (n = 32) are spherical to subspherical, with smooth colourless bilayered oocyst wall, 1.0 µm thick (outer layer 0⋅8 µm, inner 0.2 µm thick). Oocyst with a polar granule, an oocyst residuum and two spheroidal to subspheroidal sporocysts. Oocyst length, 23.8 (20.4-25.0) µm; oocyst width, 22.5 (20.0-24.6) µm; a shape index of 1.06, with Stieda, substieda bodies. Micropyle is absent. Sporocysts with compressed sporocyst residuum and four sporozoites. Sporocyst length, 14.4 (12.5-15.2) µm; sporocyst width, 11.2 (10.6-14.0) µm, sporocyst L/W ratio, 1.29. Necropsy of the bird identified haemorrhaging along the ileum and jejunum, which is where Isospora oocysts were also mostly detected. Molecular analysis was conducted at three loci; the 18S, 28S ribosomal RNA and the mitochondrial cytochrome oxidase (COI) gene. At the 18S locus, I. streperae n. sp. exhibited 99.5% and 99.4% similarity respectively to an Isospora sp. (MS-2003) from a Southern cape sparrow (Passer melanurus melanurus) and Isospora dovati from a domestic pigeon (Columba livia domestica). At the 28S locus, I. streperae n. sp. exhibited 96.9% similarity to an Isospora sp. (MS-2003) from a grosbeak starling (Scissirostrum dubium) and 95.8% similarity with the Isospora sp. (MS-2003) from a Southern cape sparrow. At the COI locus, I. streperae n. sp. exhibited 95.0% similarity to Isospora sp. from a yellow-necked mouse (Apodemus flavicollis) from the Czech Republic. Based on morphological and molecular data, this isolate is a new species of Isospora, which is named Isospora streperae n. sp. after its host, the grey currawong (Strepera versicolour plumbea).

    The family Discodorididae was previously represented by 11 species in Brazil; however, recently collected specimens from several localities in Rio de Janeiro, in addition to the study of material previously deposited in scientific collections, revealed the existence of 13 taxa: Diaulula greeleyi (MacFarland, 1909), Discodoris hummelincki (Ev. Marcus & Er. Marcus, 1963) comb. nov., Discodoris branneri MacFarland, 1909, Geitodoris pusae (Er. Marcus, 1955), Hoplodoris hansrosaorum Domínguez, García & Troncoso, 2006, Jorunna spazzola Er. Marcus, 1955, Jorunna spongiosa sp. nov., Paradoris mulciber (Ev. Marcus, 1971), Platydoris angustipes (Mörch, 1863), Rostanga byga Er. Marcus, 1958a, Taringa telopia Er. Marcus, 1955, Taringa iemanja sp. nov., and Thordisa diuda Er. Marcus, 1955. Discodoris voniheringi MacFarland, 1909 was previously regarded as nomen dubium, and this view is maintained in the present study. Three new records for the Brazilian coast are recognized among these 13 taxa; the previous record of Diaulula phoca (Ev. Marcus & Er. Marcus, 1967a) is rectified as Discodoris hummelincki comb. nov., constituting the first record of this species from Brazil; two new species, Taringa iemanja sp. nov. and Jorunna spongiosa sp. nov., are described in anatomical detail. The following taxa, which were formerly considered junior synonyms of species studied in this work, have been revalidated: Diaulula nayarita (Ortea & Llera, 1981), from the Pacific coast of Costa Rica, which differs from Diaulula greeleyi in the length and width of caryophyllidia; Discodoris mortenseni Ev. Marcus & Er. Marcus, 1963, from the Caribbean, which is likely to belong to Jorunna, yet differs from Jorunna spazzola in body size and coloration, radula appearance, and number of lamellae in the rhinophores; Jorunna luisae Ev. Marcus, 1976, which differs from Jorunna spazzola in the reproductive system, mainly in the size and shape of the accessory gland; and Thordisa azmani Cervera & Garc

    The Early Miocene vegetation of western Styria, Austria, is reconstructed on the basis of detailed investigations of leaves and diaspores from the mining area Oberdorf N Voitsberg. In this paper, the flora and probable vegetation are compared with other assemblages of similar age from the Czech Republic and Germany to elucidate the diversity of wetland and mesophytic plant communities. The floristic composition and the vegetational units represented in Oberdorf are compared to the middle part of the Most Formation (M Most Fm), Cypris Shale, Mydlovary Formation (Mydlovary Fm) of Bohemia, and the Wackersdorf mining area of Bavaria. Among these sites, Oberdorf is extremely poor in hydrophytes and reed-like monocotyledons, indicating rare pond-like habitats as well as possibly more closed swamp forest conditions than, e.g. in the M Most Fm. In Oberdorf, relatively high pH-values in the lignite-forming swamps and the possible scarcity of acidic, nutrient-poor (sandy) soils have probably influenced the floristic composition of the azonal communities. The peat-forming associations in all regions share the abundance of Glyptostrobus europaeus. However, distinct differences in the accompanying elements, such as Taxodium dubium (present and abundant only in the M Most Fm) indicate even stronger floristic variability of Early(/Middle) Miocene peat-forming and riparian plant communities than previously expected. The virtual absence of Pinus, Engelhardia, Comptonia, and probably also of Quercus kubinyii/Quercus drymeja in the megafossil record of Oberdorf can possibly be explained by the edaphic conditions. The abundance of Sequoia abietina (absent in all the other compared sites), which we assign to riparian (and mesophytic) forests in Oberdorf, may have been favoured by rich alluvial soils.In the mesophytic associations, thermophilous elements of the Lauraceae, Mastixiaceae, Symplocaceae, and Rutaceae are diverse. Usually they include Trigonobalanopsis rhamnoides

The therapeutic use of these plants involves several steps in the supply chain: origin, harvest, drying, storage, form of preparation by the user and use. The aim of this documental study of exploratory nature was to survey the scientific literature about the problems associated with each of those steps and discuss the issues related to the lack of studies to prove the pharmacological efficacy and the absence of toxicological risks, as well as the autodiagnosis practice. The 20 plants most commercialized in a large market of Rio de Janeiro City in August 2007 were the basis for the documental survey of the present study. Of these, six had proven toxic properties depending on their preparation and use: arnica (Solidago chilensis Meyen, aroeira (Shinus terebinthifolius Raddi., rue (Ruta graveolens L., "babosa" (Aloe vera L., comfrey (Symphytum officinale L. and pennyroyal (Mentha pulegium Lam. & DC..

    should again be used not only for the species originally described from cattle in Germany but also for morphologically indistinguishable taxa recently reported from cattle under the names S. sinensis and S. rommeli. Because of the morphological similarity between S. bovifelis and S. sinensis, it is likely that cats also act as definitive hosts for S. sinensis. The present paper also gives a thorough review of all research in the 1970s pertaining to S. bovifelis, including its development in cats and cattle; a review of reports of S. bovifelis-like sarcocysts in cattle, water buffaloes and other hosts; and a review of reports of the taxon currently named S. hirsuta in cattle. The usage of the name S. sinensis versus Sarcocystis dubeyi for the S. bovifelis-like taxon in water buffaloes is discussed, and the latter name is found to represent a nomen dubium since the original description concerned a mixture of a S. sinensis- and a Sarcocystis hominis-like species. Based on available transmission (TEM) and scanning electron microscopy (SEM) images, the three-dimensional configuration of the cyst wall protrusions of S. bovifelis/S. sinensis and the current S. hirsuta has been inferred and is described. The protrusions of S. bovifelis/S. sinensis are shaped like soft plastic tubes, having a cylindrical basal portion and a flattened distal portion, making them prone to fold over. The protrusions of the current S. hirsuta are thin, flattened and flexible rectangular structures (like a soft cover note book), which are attached to the cyst surface with a narrow stalk. The appearance of both types of protrusions in ultrathin sections viewed by TEM is highly dependent on how the sarcocysts and the protrusions themselves have been sectioned.

A semeadura foi efetuada em bandejas, mediante a utilização do substrato areia. As características avaliadas foram emergência e índice de velocidade de emergência. Concluiu-se que sementes de jatobá submetidas à escarificação, seguida de embebição, exibem plântulas mais vigorosas. A escarificação sem embebição pode ser recomendada como tratamento pré-germinativo para sementes de orelha-de-negro. Seguida ou não de embebição, a escarificação foi também eficiente na quebra de dormência de sementes de guapuruvu. Quanto à dormência de sementes de madeira-nova, nenhum tratamento foi eficiente para superá-la.
