Cancer stem cells exhibit close resemblance to normal in phenotype as well function. Hence, studying cell behavior is important understanding cancer pathogenesis. It has recently been shown that human breast can be enriched suspension cultures mammospheres. However, little known about the of these long-term cultures. Since extensive self-renewal potential hallmark cells, we undertook a detailed phenotypic and functional characterization mammospheres over passages.Single suspensions derived...
RNA interference (RNAi) is a set of intracellular pathways in eukaryotes that controls both exogenous and endogenous gene expression. The power RNAi to knock down (silence) any interest by the introduction synthetic small-interfering (si)RNAs has afforded powerful insight into biological function through reverse genetic approaches borne new field therapeutics. A number questions are outstanding concerning potency siRNAs, necessitating an understanding how short double-stranded RNAs processed...
Complex generics are generic versions of drug products that generally have complex active ingredients, formulations, routes delivery, dosage forms, drug-device combination products, or other characteristics can make it to demonstrate bioequivalence develop as generics. These (i.e. generics) an important element the United States (U.S.) Food and Drug Administration's (FDA's) Generic User Fee Amendments (GDUFA) II Commitment Letter. The Center for Research on Generics (CRCG) was formed by a...
Abstract A series of mono ferrocene Schiff-base porphyrins in which the unit is disposed different orientations to porphyrin core have been synthesized from meso-5(o or p)aminophenyl-10, 15, 20-triphenyl-21,23-H-porphyrin and ferrocenealdehyde. The optical magnetic resonance spectral features these derivatives reveal weak interactions between units. kinetics metal incorporation into free-base ferrocenyl indicate steric induced by unit. Electrochemical redox behaviour compounds shows that...
Studies on combining ability and heterosis were carried out at Agricultural Research Farm, PAJANCOA & RI, Karaikal, during kharif 2013 for thirteen agronomic yield traits viz., 100 grain weight, 30 single cross hybrids developed using 6 x full diallel method. The analysis revealed the presence of higher magnitude SCA than GCA variance all characters under study. ratio additive to dominance was lower unity traits, indicating non variance. Among parents, inbred line namely UMI 213 found be...
Abstract Diazo coupling reactions of nickel (II) complexes 4, 9-dimethyl-5, 8-diazadodeca-4, 8-diene-2, 11-dione and 6, 9-trimethy1-5, 8-diene-2,11-dione in aqueous methanol have been studied. It is shown that the diazo reaction proceeds selectively leading to asymmetric mono(glyoxalarylhydra-zoneimino) symmetric bie (glyoxalaryl-hydrazoneimino) complexes. Synthesis these types has achieved by direct synthesis from coupled Schiff bases derived β-diketones 1,2 diamines acetate. The products...
A total of 64 medium duration rice accessions were evaluated for their genetic variability and divergence during Rabi season 2020 at Pandit Jawaharlal Nehru College Agriculture Research Institute, Karaikal. Analysis variance revealed significant differences all the traits considered study. The spikelets per panicle filled grains recorded high GCV as well PCV thereby indicating that these would be improved effectively through selection. Other yield component viz., plant height, productive...
Abstract— Intramolecular donor‐acceptor systems bearing porphyrins covalently linked to phenol‐phthalein at various distances and different orientations have been synthesized. Optical absorption emission spectra magnetic resonance studies reveal interaction between the porphyrin unit lactone/semiquinone forms of phenolphthalein. The charge‐transfer quenching fluoresence in these is found be more pronounced compared intermolecular systems. lifetime are interpreted terms intramolecular...
