Calcifying fibrous pseudotumor in association with hyaline vascular type Castleman′s disease
Azam Muhammad,Husen Yousuf,Pervez Shahid
Indian Journal of Pathology and Microbiology , 2009,
Abstract: Calcifying fibrous pseudotumor is a recently described rare entity. It is considered as sclerosing end stage of inflammatory myofibroblastic tumor. An association with hyaline vascular type Castleman′s disease has also been described. We report a case of a 13-year-old boy who presented with pain in epigastrium. Computed tomography scan of abdomen revealed a circumscribed mass arising from the gastric wall along the greater curvature. Histology revealed a tumor composed of spindle cells present within the dense hyalinized collagenous tissue. Lymphoplasmacytic infiltrate was seen along with lymphoid follicles, dystrophic and ossifying calcification. Tumor cells were focally positive for alpha smooth muscle actin and negative for anaplastic lymphoma kinase protein.

Abstract: The effect of stock-plant etiolation on adventitious rooting of single-node leafy cuttings (SNCs) made from coppice shoots from different age groups of donor plants were investigated for teak (Tectona grandis Linn. f.). When donor plants age were 1-, 2-, 3-, 4-, and 5-year-old, they were coppiced and maintained in the dark for etiolation, while a parallel set was kept in normal light in an open environment. After 20 days, coppice shoots were made into SNCs which were cultured under intermittent mist for rooting. Stock-plant etiolation significantly increased percent rooting, shoot and root length, and number of roots per SNC, but callusing at the base of SNCs decreased. Etiolated SNCs have shown 71.7% rooting, whereas for controls (non-etiolated), the response was 41.7%. The effect of aging on callusing, rooting and sprouting of etiolated and non-etiolated coppice shoots cuttings varied widely. Aging of donor plants decreased rooting and sprouting capability in SNCs and increased callusing at the base of etiolated cuttings. The results showed that stock-plant etiolation in 1-, 2-, 3-, 4-, and 5-year-old donor plants hastened rooting potential by rejuvenation of coppice shoots.

Open Journal of Forestry (OJF) , 2013, DOI: 10.4236/ojf.2013.31003
Abstract:

Fodder and fuel wood deficiency in the Himalayan region is well recognized. Rural inhabitants are exploiting these forest resources for their livelihood for generations which leads to severe deforestation. The aim of this study was to identify the fast growing fodder and fuel wood tree species of Garhwal Himalayas at nursery stage with wider relevance and great potential for extensive afforestation programmes. Seed of Bauhinia purpurea L., Bauhinia retusa Roxb., Bauhinia variegate L., Celtis australis L., Ficus nemoralis Wall., Ficus roxburghii Wall., Grewia optiva Drummond, Leucaena leucocephala (Lam.) de Wit, Melia azedarach L., Ougeinia oojeinensis (Roxb.)

Changes of Soluble Sugars and Enzymatic Activities During Adventitious Rooting in Cuttings of Grewia optiva as Affected by Age of Donor Plants and Auxin Treatments

American Journal of Plant Physiology , 2012,
Abstract: Rooting and sprouting traits of single-node leafy cuttings (SNCs) of Grewia optiva have been studied in relation to age of donor plants and auxin treatments. SNCs from 1-, 5-, 10- and 15-year- old donors and treated IBA 3000 mg L-1 gave the best responses. Periodic sampling was performed to examine Total Soluble Sugar (TTS), Indole Acetic Acid (IAA) oxidase and peroxidase (PER) activities in the rooting zone during Adventitious Root Formation (ARF). TTS decreased with passage of time from 0 to 40 days of analysis. Auxin treatments exhibit higher TSS in all donors. IAA-oxidase and PER reduced with maturation. IAA-oxidase was highest in untreated cuttings while auxin treatments had enhanced PER activity. IAA-oxidase was found to decrease up to 20 days and increased thereafter. PER increased with time from the day of planting upto its 30 days, followed by a remarkable decline at 40, irrespective of age of donor plants or auxin treatments. Both enzyme activities remained higher in SNCs of 1-year-old donors which rooted more profusely as compared other donors. Present study suggests auxin treatments have activated carbohydrate metabolism to release energy for ARF. IAA-oxidase and PER activities seems to involve for triggering, initiation and elongation of root primordia.
MASALAH PENDIDIKAN DI PRANCIS DALAM KARYA RABELAIS, MONTAIGNE DAN ROUSSEAU

Abstract: In the 16th., 17th. and 18th. century, the first ideas of educative reform in France appeared in litterary master pieces.Rabelais wrote his critics and proposals on child education in his stories Pantagruel (1532) and Gargantua (1534),developped later in the Essays (three volumes) written by Montaigne and in Rousseau’novel, Emile. Actually the sameideas were supported also by Descartes in Discours de la Méthode (1637) and Voltaire in L’Ingénu (1767). The centralissue was the opposition between the old system of education focusing on learning by heart and theories and the systemthey proposed which gave importance on the formation of the way of thinking, in a pleasant learning atmosphere, inrelation to real life and nature. Officially French education reform was started by the Minister of Education Jules Ferryin 1880 in the decrees proclaming compulsory education in the primary school, free of charge, and the separationbetween secular and religious education
Role of Anthraquinones as a Marker of Juvenility and Maturity in Response to Adventitious Rooting of Tectona grandis

American Journal of Plant Physiology , 2012,
Abstract: Adventitious root formation in woody plants is highly influenced by the process of physiological ageing. There are increasing efforts to identify markers for distinguishing between mature and juvenile stages of trees. However, it appears to be very little information on this aspect at the chemical and molecular levels. The aim of the work was to identify potential chemical marker of juvenile and mature state; and accomplish maximum rooting in teak (Tectona grandis Linn. f.) leafy shoot cuttings. Experiments with teak leafy shoot cuttings of three different physiological ages 30- and 15-year-old (mature); and 2-month-old (juvenile) were conducted in mist propagation system. Maturity of donor teak plants decreased rooting ability. Cuttings obtained from 2-month-old donors rooted more profusely in comparison to 15- and 30-year-old donors. Indole-3-butyric acid treatment at 4000 mg L-1 significantly increased rooting percentage and produced highest number of roots. High Performance Thin Layer Chromatography (HPTLC) analysis of anthraquinones (AQs; C14H8O2) was utilized to detect qualitative and quantitative differences in AQs in stem tissues from 2-month, 15- and 30-year-old donor plants. The HPTLC analysis showed that AQs varied from 2.8 to 18.3% in cuttings derived from 2-month-old donor plants, while the variations were 4.9 to 27.3% and 11.8 to 43.4% in those from 15- and 30-year-old donor plants, respectively. Altogether, data support that AQs could be a reliable marker for maturity vis-à-vis juvenility in teak.

An Outline of the Quaternary Stratigraphy of Austria
Dirk van Husen,Jürgen M. Reitner
E&G : Quaternary Science Journal , 2011, DOI: 10.3285/eg.60.2-3.09
Abstract: Es wird ein überblick über die in sterreich verwendete Quart r-Stratigraphie gegeben. Die stratigraphische Gliederung der kartierbaren Sedimenteinheiten basiert teilweise auf Kriterien der Lithostratigraphie (lithologischer Eigenschaften) und jenen der Allostratigraphie (z.B. Diskonitinuit ten). Für das Altpleistoz n (2.58–0.78 Ma) fehlen bis jetzt Spuren einer Vergletscherung. Die wenigen und isolierten Sedimentvorkommen belegen fluviatile Akkumulation und L ssablagerung in der Umgebung der Flüsse. Pal omagnetisch korrelierte L ss-Pal oboden – Sequenzen wie das Profil Stranzendorf mit der Gauss/Matuyama – Grenze bzw. Neogen/Quart r – Grenze dokumentieren in übereinstimmung mit den globalen δ18O Werten etwas w rmere Bedingungen als im Mittelpleistoz n (0.78–0.13 Ma). Vier Gro vergletscherungen (Günz, Mindel, Ri und Würm) sind für Mittelpleistoz n und Jungpleistoz n belegt. Diese sind mit Sedimenten aus der Vorsto phase überlagert von Grundmor ne, Endmor nen im Alpenvorland und damit verknüpfte Terrassenschüttungen sowie L ssakkumulation dokumentiert. Daraus ist die klimagesteuerte Sedimentation im Zusammenhang mit dem Vorsto der Gletscher, der Ausbreitung des Permafrostes und der Frostschuttbildung bis ins Vorland erkennbar. Die jüngsten Gro vergletscherungen Ri und Würm werden aufgrund geochronologischer Daten mit den Marinen Isotopenstufen (MIS) 6 und 2 korreliert. Für Günz und Mindel scheint eine Gleichzeitigkeit mit den Phasen massiver globaler Klimaverschlechterung w hrend MIS 16 und MIS 12 plausibel. Dokumente für die schw cheren Glaziale wurden bisher nur in L ssprofilen (z.B. Krems Schie st tte) gefunden.
