. (1993): Samsun'un vezirköpru ilçesinde kizilcik'in (Cornus mas L.) seleksiyon yoluyla islahi üzerinde bir araştirma . (A research on the selection breeding of Cornelian cherries ( Cornus mas L .) grown in natural flora of Vezirköprü province of Samsun
Both resistance genes
. The gene
is derived from two different translocations: 1BS/3Ag (‘Amigo’) or 3DS/3Ag (‘Agent’). The use of molecular markers makes selection easier during the breeding process as well as in the selection of the parents. In this study, two markers were used to identify the gene
) and four different markers (J9/1-2
) were available to search for the gene
. The GbF/
marker for gene
worked well, but the SCAR marker SCS265
proved to be easier to use in MAS. SCAR markers SCS1302
proved to be highly reliable and effective for gene
not only in Agent-derived sources but also in ‘Amigo’ derivatives. The STS marker J9/1-2
and the SCAR marker SC-H5
required several modifications and were effective only in ‘Agent’ offsprings.
Az eltérő nyelvekkel és nyelvhasználattal szembeni türelmetlenség elterjedt jelenség az európai típusú kultúrákban, s a mögöttes ideológia azonos, legyen szó más nyelvek vagy a standardtól eltérő nyelvváltozatok megbélyegzéséről. Az egyes európai államok azonban eltérnek egymástól azt illetően, hogy hogyan viszonyulnak a köznapi szinten meglévő nyelvi előítéletekhez. A tanulmány egy 1999-ben végzett, 4 országra kiterjedő vizsgálat eredményeit közli: a norvég, a svéd és a görög „nyelvművelő” intézményekkel veti össze a magyart. A vizsgálat rávilágít arra, hogy a hivatalos magyar nyelvpolitika a nyelvi diszkriminációt - akaratán kívül is - nagy mértékben támogatja, szemben például a norvég gyakorlattal, ahol az állam nyelvpolitikai lépései következetesen a nyelvi jogok tiszteletben tartását célozzák.
Sungai Mas was an ancient port-kingdom located on West Coast of Peninsula Malaysia in a district of Kota Kuala Muda, Kedah,
Malaysia. The port-kingdom evolved as an entrepot since fifth century AD and continuously visited by international trader
from India, China, Middle East and Europe until eighteenth century AD. Sungai Mas was also one of the Indo-Pacific beads making
centers in Southeast Asia since sixth to thirteenth century AD and also produced pottery and brick. X-ray fluorescent analysis
(XRF) on Sungai Mas Indo-Pacific beads is carried out to determine whether the glass beads originated from Arikamedu, India
or locally made by community in Sungai Mas. Totally, twenty-two samples of beads and beads materials assayed by XRF were chosen.
Contents of nine major elements and nine trace elements, which might be present of flux, stabilizer, colorants or opacifier
were examined. The elements Si, Na, K, Ca, Fe, Al, Ti, Mn, Mg, Cu, Pb, Zr, Sr, Ba, La, U, Ni and Cr were detectable in all
samples. The concentration of elements found are discussed in terms of flux, silica or lead base glass, color and/or opacity
of the glass beads and glass samples. The result showed that Sungai Mas produced their own Indo-Pacific beads from sixth to
thirteenth century AD.
Magnesium aluminum silicate (MAS) glass samples with different concentrations of alumina (7.58 to 14.71 mol%) were prepared
by melt and quench-technique. Total Mg content in the form of MgF2+MgO was kept constant at 25 mol%. MAS glass was converted into glass-ceramics by controlled heat treatment at around 950C.
Crystalline phases present in different samples were identified by powder X-ray diffraction technique. Dilatometry technique
was used to measure the thermal expansion coefficient and glass transition temperature. Scanning electron microscopy (SEM)
was employed to study the microstructure of the glass-ceramic sample. It is seen from X-ray diffraction studies that at low
Al2O3 concentrations (up to 10.5 mol%) both MgSiO3 and fluorophlogopite phases are present and at higher Al2O3 concentrations of 12.3 and 14.7 mol%, fluorophlogopite and magnesium silicate (Mg2SiO4), respectively are found as major crystalline phases. The average thermal expansion co-efficient (aavg) of the glass samples
decreases systematically from 9.8 to 5.510-6C-1 and the glass transition temperature (Tg) increases from 610.1 to 675C with increase in alumina content. However, in glass-ceramic samples the aavg varies in somewhat
complex manner from 6.8 to 7.910-6C-1 with variation of Al2O3 content. This was thought to be due to the presence of different crystalline phases, their relative concentration and microstructure.
The ascorbic acid, total polyphenols, total anthocyanins and mineral content, together with antioxidant activity, was determined in five Czech, two Ukrainian and two Austrian cultivars of cornelian cherry (Cornus mas L.) widely grown in the Czech Republic. Ascorbic acid content varied between 199–433 mg kg−1, total polyphenols between 2174–6143 mg kg−1, and total anthocyanins between 61–253 mg kg−1. All fruits were good sources of major metals (K, Ca, Mg, Fe, and Mn) and trace elements (Cu, Zn, and Cr). The antioxidant activity was determined by EPR and DPPH radical scavenging assay and ranged from 29.5% to 67.2%. There was a linear relationship between antioxidant activity and total polyphenol content. Based on the obtained results, Ekotišnovský, Fruchtal, and Ruzyňský cultivars were recommended for further investigation and breeding programme of cornelian cherry fruit in the Czech Republic.
The multi-elemental content of sixteen glass beads and eight glass samples from archeological site Sg Mas in Bujang Valley
(finding from 5 th to 14 th century) were assayed by neutron activation analysis (NAA). Ten beads differed in colour and eight
of them were opaque. Contents of twentyfour elements, which might be present in the samples as a flux, stabilizer, colorants
or opacifier were examined. The elements Al, Br, Cl, Co, Cr, Fe, Hf, K, Mn, Na, Sc,Th, Zn and Zr were detectable in all samples.
On the other hand, concentration of the elements As, Ba, Ca, Cs, Rb, Sb, Ta, Ti, U, and V were below the detection limit in
some samples. The concentration of elements found are discussed in terms of color and/or opacity of the glass bead and glass
samples. Although the elemental composition does not fully explain the color and opacity of the studied materials, it can
still be used as fingerprint of the glass used for the bead making.
The vasodilatory effect of angiotensin 1–7 (Ang 1-7) is exerted in the vascular bed via Mas receptor (MasR) gender dependently. However, the crosstalk between MasR and angiotensin II (Ang II) types 1 and 2 receptors (AT1R and AT2R) may change some actions of Ang 1-7 in renal circulation. In this study by blocking AT1R and AT2R, the role of MasR in kidney hemodynamics was described. In anaesthetized male and female Wistar rats, the effects of saline as vehicle and MasR blockade (A779) were tested on mean arterial pressure (MAP), renal perfusion pressure (RPP), renal blood flow (RBF), and renal vascular resistance (RVR) when both AT1R and AT2R were blocked by losartan and PD123319, respectively. In male rats, when AT1R and AT2R were blocked, there was a tendency for the increase in RBF/wet kidney tissue weight (RBF/KW) to be elevated by A779 as compared with the vehicle (P=0.08), and this was not the case in female rats. The impact of MasR on renal hemodynamics appears not to be sexual dimorphism either when Ang II receptors were blocked. It seems that co-blockade of all AT1R, AT2R, and MasR may alter RBF/ KW in male more than in female rats. These findings support a crosstalk between MasR and Ang II receptors in renal circulation.
-five species. Among Cornus species, Cornus mas L. are known as the European and Asiatic cornelian cherry and are grown for their edible fruits. Wild grown cornelian cherry trees are abundant in rural areas in mostly Balkan and east European countries and
