The genus Cucurbita has been mentioned as a good source of carotenoids, including β-carotene, which is precursor vitamin A. However, the variability observed for denotes individual need to invest in species. An experiment was carried out with aim evaluating content total carotenoids and β-carotene C. maxima germplasm. Treatments consisted 23 accessions two commercial cultivars maxima. pulp colo...

Abstract We report on the annual variation of quiet-time suprathermal ion composition for C through Fe using Advanced Composition Explorer (ACE)/Ultra-Low Energy Isotope Spectrometer data over energy range 0.3–1.28 MeV nuc −1 from 1998 2019, covering solar cycle 23's rising phase Solar Cycle 24's declining phase. Our findings are: (1) abundances resemble CIR-associated particles during minima; ...

DsRed, a brilliantly red fluorescent protein, was recently cloned from Discosoma coral by homology to the green fluorescent protein (GFP) from the jellyfish Aequorea. A core question in the biochemistry of DsRed is the mechanism by which the GFP-like 475-nm excitation and 500-nm emission maxima of immature DsRed are red-shifted to the 558-nm excitation and 583-nm emission maxima of mature DsRed...

A system for plant regeneration from individual cells or explants is essential for the application of genetic engineering. In Cucurbitaceae, in vitro regeneration has been reported across a wide spectrum of crops, including summer squash (Cucurbita pepo L.) (7), winter squash (Cucurbita maxima Duch.) (9), bottle gourd (Lagenaria siceraria Standl.) (6) and, recently, figleaf gourd (Cuburbita fic...

Acetonic extracts of melon pumpkin, Cucurbita maxima (Duchesne), Sweet Orange, Citrus sinensis (L.) and Sour Orange, Citrus aurantium (L.), were evaluated for insecticidal activity against adults of three stored product pests viz., Sitophilus oryzae (L.), Rhyzopertha dominica (Fabricius) and Tribolium castaneum (Herbst), by filter paper diffusion method (direct contact application) and fumigati...

Heptamethine cyanine dyes are attractive compounds for imaging purposes in biomedical applications because of their chemical and photophysical properties exhibited in the nearinfrared region. A series of meso amino-substituted heptamethine cyanine dyes with indolenine, benz[e]indolenine and benz[c,d]indolenine heterocyclic moieties were synthesized and their spectral properties including fluore...

We have measured the vibrationally resolved partial cross sections σv′ 1 and asymmetry parameters βv′ 1 for C K-shell photoionization of the CO2 molecule in the u shape resonance region above the C K-shell ionization threshold. The positions of both the maxima of σv′ 1 and the minima of βv′ 1 move towards the C K-shell threshold with increasing symmetric stretching vibrational excitation v′ 1 i...

Structure of Oligostatin C Oligostatin C (Ic), a basic, water-soluble, amorphous substance; m.p. 183'C (dec.), [a]21+154' (c 1, H,O), shows strong IR absorption maxima at 31003600 and 9801180 cm-1 indicative of its oligosaccharide nature. PMR spectrum of Ic in D2O shows a methyl signal at 1.38 ppm (d, J=6 Hz), a methine proton at 2.76 ppm (t, J=9 Hz) and complex signals at 5.2 5.5 ppm assignabl...

[1] PRIMELT2.XLS software is introduced for calculating primary magma composition and mantle potential temperature (TP) from an observed lava composition. It is an upgrade over a previous version in that it includes garnet peridotite melting and it detects complexities that can lead to overestimates in TP by >100 C. These are variations in source lithology, source volatile content, source oxida...
