Vanadium pincer complex: synthesis, characterization, catalysis and biological studies
Get PDFNew vanadium coordinated pincer complex is synthesized and characterized. Coordinating organic ligand (L1) is designed to afford ONO coordination mode. Metal complex (ML1) prepared by reacting VO(acac)2 with 2-hydroxy-3,5-ditertiarybutyl benzaldehyde and o-aminophenol in methanol (where acac stands for acetylacetonate). Ligand (L1) coordinates the central vanadium metal atom via ONO fashion hence occupied three coordination sites. For charge compensation vanadium retains one of the acetyl aetonate ligand and finally sixth coordination satisfied by terminal oxo group consequently attains octahedral geometry. This pincer type coordinated ligand provides strong meridonial environment to the metal center and also support to stabilize the higher oxidation state of vanadium. The complex is characterized by available analytical techniques such as Molar Conductance, UV-visible, IR, Cyclic Voltametry (CV), and Thermogravimetric Analysis (TGA). Biological behavior has been investigated towards antibacterial activity. The complex also successfully utilized as catalyst for the simple organic transformation
Statistical Analysis of Foreign Rice Phenotypes under Different Seasons of the Philippines
Get PDFKorean rice is a foreign genetic resources in the Philippines that has to be characterized for its proper germplasm utility. Ten Korean phenotypes were analyzed using correlation, clustering and principal component analyses (PCA) based on the 13 traits viz., culm length (CL), days to 50% flowering (D50F), days to maturity (DM), filled grains per panicle (FGP), flag leaf length (FLL), flag leaf width (FLW), grain length (GL), grain width (GW), grain yield (GY), plant height (PH), productive tillers (PT), spikelet fertility SF) and thousand grain weight (TGW) under different seasons of the Philippines. It was found out that Korean phenotypes had earlier D50F and DM, shorter PH and CL, more PT, FGP and SF, and higher GY under dry than wet season. Each season had three groups based on the clustering analysis with a pattern of group 1 having phenotypes with heavy TGW, early D50F and DM, short PH and FLL; and more FGP, SF and GY; group 2 having long CL, wide FLW, light TGW; and late D50F and DM; and group 3 having short CL, narrow FLW and low PT. Correlation in FGP, PT and SF to GY was consistently high positive (r≥0.68) in two seasons. Also, PCA consistently showed that GY, PH and PT were the highest contributor of variation with an average of 21.42% in two seasons. Korean GY therefore was highly variable but attaining higher GY can be possible by utilizing grain-filling (FGP and SF) and productive tillering (PT) traits as selection indices in the breeding program
Study of Anthocyanin Content, Antioxidant Property, UV Absorbance & SPF Analysis of A Few Petals
Get PDFHerbal medicine has been commonly used over the years for treatment and prevention of diseases and health promotion as well as for enhancement of the life span and quality of life. It is a well-known fact that Traditional Systems of medicine always played an important role in meeting the global health care needs. Herbal cosmetics use phytochemicals from variety of plants. The botanical ingredients present influence biological functions of skin and provides nutrients necessary for healthy skin. Skin care is major problem faced by many people due to increase in pollution and other factors. The aim of this study was to determine the Anthocyanin content, Antioxidant property, UV Absorbance & Sun Protection Factor (SPF) of few petals namely, Rose, Bougainvillea, Chrysanthemum, Dahlia, Marigold and Ixora. It was found that dry ethanolic and aqueous extracts of Dahlia, Chrysanthemum and Rose has high anthocyanin content and SPF value above 30 compared to other flower petals. Skin cream was prepared using aqueous extract of these three petals. Lavender oil was used for fragrance. Survey was conducted through questionnaire. Though many plants are known to cure various diseases, knowledge of traditional medicine used by communities in India has been lost due to lack of documentation. Hence efforts were made to visit villages in Karnataka & Mumbai to collect data of plants used for primary health care
Rescue of distressed elephants in Southern India, A case studies of threats to wild elephants caused by human development activities and intervention
Get PDFElephas maximus indicus, an endangered herbivore is a single extant species inIndiawith a vital role in any ecosystem in which it survives. Conservation of elephants inIndiais the need of the hour as they are the keystone species capable to stop the progression of grassland to woodlands or thicket by weeding out the trees and shrubs. The size of the herbivore makes it difficult for the conservation management issues like human-elephant conflict or rescue operations in case of distressed elephants. In this paper we have reported four case studies in which rescue operations has yielded success by the appropriate sequence of physical methods. Though there are notable difference in the situations, effective planning and execution of the rescue operation based on the elephant in distress and the topology has made each rescue case a unique operation and hence we have discussed the specific determinants in each case and the operational procedure which would give success in each cases

Evaluation of Active RT-PCR (NS1 Ag Assay) Compound for Dengue Haemorrhagic Fever (Aedes aegypti sp).
Get PDFThe global prevalence of dengue cases has increased in India. The increasingly widespread distribution and the rising incidence of dengue virus infections are related to increased distribution of Aedes aegypti, an increasingly urban population, and increasing air travel. Several countries show that the age of the reported dengue cases has increased from 5-12 years, to older children and young adults. Although shock and plasma leakage seem to be more prevalent as age decreases, the frequency of internal hemorrhage rises as age increases. Increase in liver enzymes found in both children and adults indicated liver involvement during dengue infections. Pre-existing liver diseases in adults such as chronic hepatitis, alcoholic cirrhosis, and hemoglobinopathies may aggravate the liver impairment in dengue infection. Fulminant hepatitis is a rare but well described problem in adult patients with dengue infection. Currently, no specific therapeutic agent exists for dengue. The early recognition of dengue infection, bleeding tendency, and signs of circulatory collapse would reduce mortality rates in adult patients with dengue infection
Molecular docking studies of bisazo derivatives of 4-Acetyl resorcinol against lung cancer protein EGFR
Get PDFLung cancer is one of the malignant diseases mostly caused by tobacco users. EGFR, proto oncogene plays an important role in many biological processes apoptosis, transcriptional regulation, cell differentiation, cell spreading and mobility. The mutation occurs in EGFR, the normal function of EGFR is over expressed and leads to develop lung cancer. In this present study, we have developed lung cancer drug from bisazo derivatives through molecular docking studies against EGFR using Glide. From the docking results the compound I, IV and V have a better life score when compared to other compounds. The ADME properties were carried out for five bis azo molecules. These compounds are under acceptable range with predicted ADME properties. From the In-silico docking studies, we conclude the compounds I, IV and V are good drug for lung cancer and inhibit over expression of EGFR in human
