AbstractAbstract
[en] The ingeritance of apiculus colour and its relationship to salinity (4,000 ppm) was studied in four rice varieties by using water-culture techniques. The apiculus colour in Jhona 349 and Magnolia seems to be controlled by two pairs of CBr and Sp genes complementary in nature. No relationship could be established between the apiculus pigmentation and resistance to salinity

AbstractAbstract
[en] Optimized compositions of a four-color CMYK plus a green pigment have been prepared by the ceramic method: cobalt doping in Celsian (Ba0,9Co0,1)Al2Si2O8 (cyan), chromium in armalcolite (MgFe)(Cr0,2Ti2,8Fe)O10 (magenta), nickel in geikielite (Mg0,5Ni0,5)TiO3 (yellow), the perovskite CrNdO3 (green) and the same perovskite mineralized with alkaline earth fluorides (BaF2 and MgF2) (black). Both pigment powder and glazed sample in a conventional double firing frit (1050°C) have been characterized with respect to its colorimetric performance by the model CIEL*a*b*, its cooling capacity (as cool pigments) by the measurement of the solar reflection index SRI and its photocatalytic capacity by means of the OrangeII degradation test. The obtained results are compared with those obtained with commercial pigments of the CMY family of the zircon. The results indicate that the coloration of the powders and the enamelled samples is more intense, with L* values lower than the zircon homologous pigments, whereas the obtained chroma with the pigments of the zircon is better (b* negative for cyan, a* positive for magenta and b* positive for yellow). Regarding its cooling capacity, the results indicate high SRI values for all samples. In the case of Celsian SRI is higher than for vanadium-zircon, the green of perovskite slightly exceeds the eskolaite Cr2O3 value that is taken as reference. In the case of the black perovskite, very low SRI values are measured (SRI=0 in the case of powder) and associated with high middle-infrared emissivity values, making it interesting as a pigment for absorbent substrates in solar collectors. The photocatalytic capacity over OrangeII indicates half-life values around 55-70minutes, lower than those measured in zircons (110-190minutes).

Se han preparado por el método cerámico composiciones optimizadas de una cuatricromía CMYK más un pigmento verde, basados en el dopado de cobalto en celsiana (Ba0,9Co0,1)Al2Si2O8 (cian), de cromo en armalcolita (MgFe)(Cr0,2Ti2,8Fe)O10 (magenta), de níquel en geikielita (Mg0,5Ni0,5)TiO3 (amarillo), la perovskita CrNdO3 (verde) y la misma perovskita mineralizada con fluoruros alcalinotérreos (BaF2 y MgF2) (negro). Los pigmentos en polvo y los vidriados obtenidos con una frita convencional de bicocción (1.050°C) se han caracterizado respecto de su rendimiento colorimétrico mediante el modelo CIEL*a*b*; su capacidad refrigerante (como cool pigment), mediante la medida del índice de reflexión solar SRI, y su capacidad fotocatalítica, mediante el test de degradación de NaranjaII. Los resultados obtenidos se comparan con los obtenidos con pigmentos comerciales de la familia CMY del circón tomados como referencia. Los resultados indican una coloración intensa de los polvos y de las plaquetas vidriadas con valores L* inferiores a los pigmentos homólogos del circón, en cambio el chroma obtenido con los pigmentos del circón es superior (b* negativo para el cian, a* positivo para el magenta o b* positivo para el amarillo). Respecto a su capacidad refrigerante, los resultados indican valores SRI altos y superiores en el caso de la celsiana al del vanadio-circón, el verde supera ligeramente a la eskolaita Cr2O3, que se ha tomado como referencia, y en el caso de la perovskita negra sus valores SRI muy bajos (SRI=0 en el caso del polvo) y asociados a altos valores de emisividad en el infrarrojo medio la hacen interesante como pigmento para sustratos absorbentes en colectores solares. La capacidad fotocatalítica sobre NaranjaII indica valores de periodo de semivida en torno a 55-70min, inferiores a los medidos en los circones de referencia (110-190min).Original Title

AbstractAbstract
[en] This study was carried out to investigate the possibility of using foliar ABA application with different concentrations (50,100 and 150 meu g/L-1) in order to decrease the adverse effect of water-deficit stress. The main parameters of interest were; growth parameters; endogenous phytohormones, proline; pigments contents; number and shape of stomata; minerals concentrations; isozymes; and SDS -PAGE protein profile in Pisum sativum plant at 36 days under drought and ABA treatments. The results showed that ABA reduces the reduction in both fresh and dry weights shoot and root of Pisum induced by drought stress. Proline content was increased in response to drought and ABA treatments. Water-stress caused significant reduction in Chl. a, b, whereas application of ABA significantly increased in total chlorohpyll. Water stress significantly decreased IAA, GA concentrations and increased ABA level in leaves than these of the control. ABA treatment partially overcame the decrease in IAA and GA contents. Water stress and ABA increased the activity of (POD) and (ACP) enzymes in Pisum plants. Proteins profile of Pisum sativum in shoot revealed qualitative and quantitative changes, also appearance or disappearance of some bands. After 54 days the yield harvested and total carbohydrates and SDS -PAGE protein profile in seed were investigated. The data showed that total carbohydrates contents were significantly decreased in plant under drought and ABA partially alleviate the adverse effect of water-deficit stress. (author)

AbstractAbstract
[en] The subject of this study is the preparation of 11-cis and 9-cis retinals deuterated at specific positions of the chain with a high deuterium incorporation and a high chemical purity. The reaction of opsin with these compounds gives rhodopsin and isorhodopsin with a deuterium label on the predetermined positions of the chromophore. For the introduction of the deuterium the author has used the conversion of a propargyl alcohol into an ethylenic alcohol by the LiAlH4 reductive method. (Auth./C.F.)

AbstractAbstract
[en] Garcinia mangostana Linn,(Family; Guttiferae) is known to be a rich source of bioactive molecules including flavonoids, benzophenones and lactones. A variety of xanthones have been isolated from mangosteen plants and fruits include the hull, rind heartwood and flesh. The fruit hull is used as an astringent and also used against cholera, dysentery and diarrhoea in traditional medicinal system. Petroleum ether extraction of the dried and powered fruit hulls followed by column chromatographic separation afforded two compounds, namely, gartanin (1) (0.48% in yield, mp 146-152 ) and mangostin (2) (0.97% in yield, mp (179-180). The structures of these two compounds have been identified by UV, FT-IR, NMR and EIMS. These identifications were confirmed by comparison of melting point values with reported data in the literature

AbstractAbstract
[en] Objective: To evaluate the anatomical and visual outcome of surgical management of retinal detachment associated with chorio-retinal coloboma. Study Design: Prospective interventional case series Place and Duration of Study: This study was conducted at Al-Shifa Trust Eye Hospital Rawalpindi from Jan 2012 to Dec 2013. Material and Methods: Twenty one eyes (21 patients) that underwent surgery for retinal detachment associated with chorio-retinal colobomas were selected. Evaluation was done on the basis of type of intervention, final visual acuity and anatomical outcome and complications. Out of 21, 19(90.47 percent) eyes underwent pars plana vitrectomy with silicone oil (SO) and 2(9.52 percent) underwent primary scleral buckling surgery. SO was removed in 9 (47.36 percent) eyes at final follow up. Encircling band was placed in 12 (63.15 percent) eyes based on peroperative judgment of surgeon. Intra-operative lensectomy was performed in 6 (28.57 percent) eyes. The main outcome measures were retinal re-attachment and visual recovery. Statistical analysis was performed using IBM statistical package for social sciences (SPSS) Statistics (version 17.0, Chicago, Illinois, USA). Qualitative variables were described using percentage; quantitative data were defined using mean +- standard deviation. The pre op and post op frequency of best corrected visual acuity (BVA) was compared using Wilcoxan Signed Ranks Test. Confidence interval was 95 percent (level of significance p<0.05). Results: The mean number of operations per eye were 1.57+- 0.74; mean follow-up was 13.1 months (range 12-18). The retina remained attached in 18 eyes (85.71 percent) at final follow-up. The post op BCVA improved significantly as compared to pre op BCVA (p< 0.01). Mean pre op BCVA was counting fingers (CF) and mean post op value of BCVA was 3/60. Conclusion: Pars plana vitrectomy along with silicon oil tamponade for retinal detachment related to choroiretinal coloboma improves the long-term anatomical outcome however no significant improvement in visual acuity was observed.
