Cytochrome c (cyt c) participates in two crucial cellular processes, energy production and apoptosis, and unsurprisingly is a highly conserved protein. However, previous studies have reported for the primate lineage (i) loss of the paralogous testis isoform, (ii) an acceleration and then a deceleration of the amino acid replacement rate of the cyt c somatic(More)
The naturally occurring C17 compound dihomosesquiterpene (1), along with two known compounds (2, 3), was isolated from the ethanolic extract of Curcuma aromatica rhizomes. Compound 1 was identified as a new compound using 1D and 2D NMR (1H, 13C, DEPT, 1H–1H-COSY, HMQC, HMBC, and NOESY) spectroscopic techniques and called termioic acid A(More)
Plant nutrition and climatic conditions play important roles on the growth and secondary metabolites of stevia (Stevia rebaudiana Bertoni); however, the nutritional dose is strongly governed by the soil properties and climatic conditions of the growing region. In northern India, the interactive effects of crop ecology and plant nutrition on yield and(More)
Treatment of spore suspension of Cephalosporium acremonium ATCC 48272 with UV rays and N-methyl-N-nitro-N-nitrosoguanidine (NTG) induced mutants capable of producing higher yields of cephalosporin C. Antibiotic yield was improved from 630 micrograms/ml to 1995 micrograms/ml of the broth resulting in a high yielding mutant.
A new strain of Bacillus sp., Bacillus PE-11 isolated and identified in our laboratory was found to be a potential producer of alkaline proteinase. The production of proteinase was studied in thirteen different reported media to select the optimal production medium. In all the reported media, the medium XII of composition: glucose, 0.2%; peptone, 1.5%; salt(More)
Chemical investigation of the rhizomes of Costus speciosus led to the isolation of a new compound, 22-ketocholesteryl palmitate (1) along with four known compounds, 24-methylenecycloartanol (2), cycloartanol (3), stigmasterol (4) and linoleic acid (5). The structure of new compound was characterised by extensive 1D-, 2D-NMR and mass spectrometry (GC-MS and(More)
AIMS: Cerebellar astrocytoma occurs more often in children and young adults than in adults. They are the most common astrocytic tumours in children, accounting for 80–85% of cerebellar astrocytomas and 60% of optic gliomas. They comprise about 33% of all posterior fossa tumours in children and represent about 25% of all paediatric tumours. The aim of this(More)
Costus speciosus had been used in oriental systems of medicines, to treat diverse ailments. The present study was focused on NMR, GC-MS and UPLC/ESI-MS/MS-based metabolic profiling of C. speciosus. This metabolic study resulted in the identification of 91 and quantification of 69 metabolites. Caffeic acid derivatives previously unreported in C. speciosus(More)
