neuromelanin (nm) pigment accumulates with age in catecholaminergic neurons in man, and the ventral substantia nigra dopaminergic neurons that are the most vulnerable to degeneration in parkinson's disease (pd) contain the greatest amount of this pigment. in vitro data indicate that nm pigment is formed from the excess cytosolic catecholamine that is not accumulated into synaptic vesicles via t...
An experiment was conducted to compare a commercial corn-soybean meal diet with a pearl millet diet containing less soybean meal (-27%), alone or in combination with exogenous enzymes, on growth performance, jejunal villus development, ileal CP, and AA digestibility, and cecal microbial populations in broilers. One hundred sixty 1-d-old male Ross 508 broilers (5/cage) were randomly allocated to...
Sorghum and pearl millet are two important dry land crops that provide grain and fodder. India is the largest pearl millet producer and second largest producer of sorghum in the world. The productivity of these crops has been low due to various reasons such as unavailability of quality inputs to the farmers, lack of access to improved technologies for crop production, unavailability of credit o...
Hydroides elegans is a major fouling organism in tropical waters around the world, including Pearl Harbor, Hawaii. To determine the importance of initial surface characteristics on biofilm community composition and subsequent colonization by larvae of H. elegans, the settlement and recruitment of larvae to biofilmed surfaces with six different initial surface wettabilities were tested in Pearl ...
Two groups of commercial quality ("acceptable") pearls produced using two donors, and a group of "acceptable" pearls from other donors were analyzed using reflectance UV-Vis spectrophotometry. Three pearls with different colors produced by the same donor showed different absorption spectra. Cream and gold colored pearls showed a wide absorption from 320 to about 460 nm, while there was just sli...
the research mainly intends to evaluate performance of strontium aluminum polyphosphate as an eco friendly zinc free anticorrosion pigment in formulation of the protective primer based on epoxy resin. comparing to zinc phosphate, the most effective content of the modified pigment was determined through electrochemical impedance spectroscopy. according to pull-off, the superior sapp incorporated...
In recent years, scientists and researchers from all over the world pay much attention to carotenoid pigments as a substitute for antibiotics and synthetic chemical compounds with antioxidant property and the plants, various microorganisms including bacteria and algae are also capable of producing carotenoid pigments. In this research, the production of antimicrobial and antioxidant carotenoid ...
About 26% of the Indian population is deficient in calories and 28% in protein (Chand et al. 2003). The deficiency is most acute among the poor. The magnitude of micronutrient [iron (Fe) and zinc (Zn)] deficit is particularly alarming among children, women of reproductive age, and pregnant and lactating women (Sharma 2003). Current efforts to combat micronutrient malnutrition in the developing ...
The study of the pearl oyster Pinctada fucata is key to increasing our understanding of the molecular mechanisms involved in pearl biosynthesis and biology of bivalve molluscs. We sequenced ~1150-Mb genome at ~40-fold coverage using the Roche 454 GS-FLX and Illumina GAIIx sequencers. The sequences were assembled into contigs with N50 = 1.6 kb (total contig assembly reached to 1024 Mb) and scaff...
The pearl mouse is a model for Hermansky Pudlak Syndrome (HPS), whose symptoms include hypopigmentation, lysosomal abnormalities, and prolonged bleeding due to platelet storage pool deficiency (SPD). The gene for pearl has recently been identified as the beta3A subunit of the AP-3 adaptor complex. The objective of these experiments was to determine if the expression and subcellular distribution...
