In this paper, we investigate several topological indices in honeycomb graphs: Randić connectivity index, sum-connectivity index, atom-bond connectivity index, geometric-arithmetic index, First and Second Zagreb indices and Zagreb polynomials. Formulas for computing the above topological descriptors in honeycomb graphs are...
Read MoreCulture dependent phenotypic characterization analyses were applied to study the protease producing bacteria from Indian Soda (Lonar crater). The uniqueness of the Lonar lake water is its salinity and alkalinity. A total of one hundred and fourteen bacterial cultures were isolated from the water and sediment samples collected from the hyper alkaline saline environment of Lonar lake. The thirty two bacterial strains were found protease producing bacterial culture, out of them strain EW2 was selected for 16S rDNA sequencing, production and partial characterizations of protease on the basis of their maximum proteolytic activity. The phylogenetic position indicated the strain was related to phylum Firmicutes. Optimum enzyme activity was found to be at 80 °C and pH 9.5. The protease was highly stable over broad temperature from 40 to 90 °C, pH 7.0 – 12.0, showing excellent thermostablity and alkaline tolerant nature. The enzyme activity has enhanced by all metal ion which was tested in this studies indicating it was a metalloenzyme but inhibited by organic solvent except acetone. This...
Read MoreDengue fever is an important public health problem in tropical and sub-tropical Continent. Recently the number of severe forms of the disease, dengue hemorrhagic fever, and dengue shock syndrome are increased. Dengue virus, a arbo-virus responsible for dengue fever and spread through its vector, Aedes aegypti. Controlling the mosquito is the good strategy to prevent this disease. The traditional chemical pesticides used to control mosquito have many drawbacks, and natural products are more acceptable in this aspect. The bio-efficacy of ginger (Zingiber officinale) and turmeric (Curcuma longa) ethanolic leaf extract was assessed against the fourth instars larvae of Aedes aegypti, under the laboratory conditions. Both shows moderate activity against Aedes aegypti larvae. However, the combined treatment of both leaf extract (1:1) shows highest activity. Combination of 50 µgml-1 turmeric and 50 µgml-1 ginger killed all of the population within 24 h. This is an eco-friendly and low-cost approach, may use to control Aedes...
Read MorePhenolics have been shown to attenuate the initiation and progression of cancer. Owing to the parasitic nature, mistleoes are a rich source of phenolics and flavonoids. European mistletoe (Viscum album) formulations provide the first line of treatment for cancer by stimulating the immune system and improve the quality of life. In fact, host-associated variation has been shown to affect the therapeutic potential of the V. album preparations. Leafless Mistletoe (Viscum angulatum), a hemiparasitic plant of the Western Ghats widely used in folk medicine, contains diverse phytochemicals having anti-inflammatory properties. However antioxidant and anticancer potential of Viscum angulatum is still not investigated. In the present study, we analyzed the contents of total phenolics (TPC), flavonoids (TFC), antioxidant potential and cytotoxic potential of extracts of leafless mistletoe plants parasitic on two different host trees, Olea dioica and Flacourtia indica. The whole plant of leafless Mistletoe was extracted in organic solvents (methanol and ethanol) and water (aqueous) using rotary evaporator. In the methanolic extract, TPC of plants parasitic on O. dioica was...
Read MoreThis study was conducted to investigation the effect of humic acid and salicylic on oil yield and flavonoids glycoside of safflower plant (Carthamus tinctorius L.) grown in Iraq. After soil preparation the plant seeds were cultivated during winter growing seeds at 2015-2017 at Karbala region, South Baghdad in Iraq. The humic acid was applied at 1000, 2000 and 4000 mg/lit conception as organic flower fertilizes while the application of salicylic acid was used 50, 100 and 200 mg/lit. Twister application of bath humic and salicylic acids were done at vegetable growth stage all treatment were arranged by according randomized complete block design (RCBD) flower leaves or petals ethylic extract was done by used Soxhlet apparatus, the use HPLC his prefect liquid climter to determine the type and concentration of Pt flavonoids glycoside. Also the seed oil was obtained by expression mthai. The redaction were infeed to the S2 F3 treatment (100 mgl-1 of salicylic acid with 400 mgL-1 of humic acid) was gave height value of oil yield and...
