Comparative Protein Fraction Analysis for Commercial Hybrid Seed Purity Testing in Cotton (Gossypium HirsutumL.)

Journal of Natural Fibers (2016)

Dhandapani Raju P. Avinash H. P. Vijayakumar Ambika Rajendran Gopi Somasundaram

An experiment was designed to find out the best suited seed protein fraction for identifying the genetic contaminants in seeds of two cotton hybrids viz., CSHH 198 and CSHH 238 where its morphological and genetic differences are meager. The electrophoretic comparison of albumin, globulin, and prolamin seed protein fractions revealed that both albumin and globulin fractions are able to differentiate the hybrids from its male and female parents. The analysis of seed proteins of two cotton hybrid revealed that, albumin fraction produced six different fingerprints with highest discrimination ability than globulin fraction (three). Due to this, albumin fraction showed the added advantage in assessment of genetic purity of CSHH 198 hybrid seed lot that are contaminated with its own parental (selfed female) seeds as well as CSHH 238 cotton hybrid. In contrast, globulin fraction can only be used for identification of off type contaminations due to its own parental seeds and prolamin was unable to differentiate any contaminant. Thus, water soluble albumin protein fraction can be used to differentiate the CSHH 198 and CSHH 238 cotton hybrids and their parental line for both genetic and hybrid purity testing.

Evaluation of seedlings of oil palm germplasm from Sierra Leone and Senegal in India

Indian Journal of Horticulture (2021)

P. Murugesan Gopi Somasundaram V.P. Pandey

The oil palm (Elaeis guineensis Jacq.) germplasm of present study namely, Sierra Leone (SLE) and Senegal (SEN) are important genetic resource as their diversity is presumably very high due to their locations in the centre of origin of West Africa. A total of nine accessions each from two sources (SEN and SLE) were evaluated for vegetative growth traits in the nursery viz, seedling height, stem height, collar girth, leaf number, length of leaf, width of leaf, leaf area, petiole thickness and petiole length of the seedlings and their diversity were estimated using Shannon Weaver Index (SWI). The results revealed that accessions namely, SLE14 (66) and SLE13 (349) showed vigorous seedling growth; whereas, SEN02 (191) had shown dwarf vegetative growth. Diversity estimates ranged from 0.00 in SLE12 (186) for number of leaves and 0.954 in SEN01 (38) for collar girth. SLE01 (38) and SLE03 (17) had shown high diversity estimates and lowest diversity estimate was observed in SEN01 (284). Sierra Lone sources of accessions showed higher diversity than those from Senegal. Outcome obtained from the present nursery study can be utilized for advanced breeding evaluation in matured palms.

PRESCRIBING PATTERN OF DRUGS IN OUTPATIENT DEPARTMENT IN TERTIARY CARE HOSPITAL

Indian Journal Of Applied Research (2023)

D Camilus J. Jayasheela Gopi Somasundaram

Aim: The study was conducted to assess the prescribing behaviour for antimicrobials and various groups of drugs in tertiary care hospital in Puducherry. Prescription audit was done. Total 500 presc Method: riptions were analysed for sex wise distribution, no of patients for specic age group, antimicrobials prescribed in generic name, percentage of antibiotics, antacids, NSAIDs and multivitamins, among the prescribed drugs, groups of antibiotics, drugs prescribed from National List of Essential Medicines (2022), use ofxed drug combinations, injectable preparations if any. Results: Demographic analysis showed that out of 500 patients in OPD, most were female (53%) and in the age group between 41 to 60 years. In 500 number of prescriptions,9.96% of antibiotics were prescribed; uoroquinolones (5.42%) were prescribed more from antibiotics followed by extended spectrum penicillin (1.64%). 14.78%of antacids were prescribed; PPIs (11.28%) were prescribed more from antacids. 21.63% of NSAIDs were prescribed.11.66% were prescribed in generic names, 65.44% drugs were prescribed from National List of Essential Medicines (2022), 15.88% of FDCs were prescribed,6.13% of injectable preparations were prescribed. The rational use of antimicrobial agents is one of the main contribut Conclusion: ors to control worldwide emergence of bacterial resistance, side effects and reduced cost of the treatment

Scrutiny Of Chemical Surfactants (n-Heptane, Polyimide, PVA, PVP, SDS) Based CdO Nanoparticles For The Application Of Solar Radiation Photocatalytic And Antimicrobial Activities

Research Square (Research Square) (2021)

Gopi Somasundaram R. Jayaprakash

Abstract The chemical surfactant-based synthesis route is the C-H-based aqueous method using to form the restrained shape of Cadmium Oxide (CdO) nanoparticles. The effect of different weight percentages of n-HEPTANE, POLYIMIDE, PVA, PVP, SDS in the preparation of CdO nanoparticles is studied. The surfactants are highly influenced by particle size variation and morphology gets changed. The role of surfactant is not produced any structural change apart from the particle size which is the advantageous part of the surfactant-based synthesis. The particle sizes from X-ray diffraction (XRD) analysis were found that there is a decrease in particle size from 54 to 92 nm when using the artificial chemical additives. The firmness of the CdO nanoparticles synthesized with help of chemical surfactants was characterized by UV-vis Diffused Reflectance Spectrometer (DRS), Fourier Transformer inferred (FT-IR), and photoluminescence studies. The photocatalytic activity and antimicrobial activity is investigated on using the chemical surfactant-based CdO nanoparticles as catalyst under Solar irradiation and zone inhibition method respectively.

Biochemical changes in naturally aged seeds of soybean genotypes with good and poor storability

Legume Research - An International Journal (2018)

H. P. Vijayakumar V. Arun P. Srimathi Gopi Somasundaram S. Rajendra Prasad

Seed deterioration during storage is associated with various metabolic and chemical alterations that vary among genotypes in soybean. In the present study, five genotypes with good storability viz., kalitur, MACS 1416, EC 18761, CO1 and DSB21 and five genotypes with poor storability viz., JS 71-05, DS 228, MAUS 61, NRC 93 and DSB 24 were selected and evaluated for biochemical changes to identify the best donors for storability. Among the genotypes, all the poor storer genotypes showed faster accumulation of free amino acids, free fatty acids and malondialdehyde content as a result of oxidative stress. Poor storer genotypes also showed the increased lipoxygenase I and II enzymes activity. All the good storer genotypes showed higher anti-oxidative enzymes activity causing slower lipid peroxidation. Among the good storers, kalitur showed favourable biochemical features for storability while MAUS-61 was identified as poor storer exhibiting less favourable biochemical features.

Enhanced photocatalytic and microbial activity of bio synthesized CdO tetrahedral clogs using Hibiscus rosa sinensis leaf extract

Frontiers in Advanced Materials Research (2022)

Gopi Somasundaram Jayaprakash Rajan

Green extracts from plants, fruits, flowers are being explored worldwide to minimize the effect of toxic chemicals used in nanoparticles fabrication. The present work is based on the cadmium oxide nanoparticles (CdO NPs) were synthesized using Hibiscus rosa sinensis leaf extract at different volume concentration of 10 ml, 20 ml, 30 ml, 40 ml and 50 ml under bio synthesis process. The prepared samples were characterized by XRD, UV-DRS, PL, FT-IR, FE-SEM, EDX, HR-TEM analysis. The XRD pattern confirms the cubic structure with average particle size of 41.48 nm to 51.69 nm. The estimated band gap energy is found in the range 2.19 eV to 1.67 eV. Near UV and violet emission in PL spectrum leads the presence of crystal defects in CdO lattice. Presence of vibrational modes of chemical species in the samples, are characterized by Fourier Transform Infrared (FT-IR) spectrum. The elemental compositions are detected by using energy dispersive X-Ray analysis (EDAX). The particle size and morphology with intense magnification is confirmed by FE-SEM and TEM- SAED analysis. The antibacterial and fungal activities of Hibiscus rosa sinensis leaf extract CdO nanoparticles are tested for different bacterial organisms like Staphylococcus aureus, Bacillus substilis, Escherichia coli and Salmonella paratyphi and fungal organism like Candida albicans, Aspergillus niger and Aspergillus fumigates under the zone inhabitation method. The photocatalytic activities of the CdO samples on degradation of Methylene Blue azo dye under UV light irradiation are also studied.
