Opis:
The aim of this report is giving the importance in need of ground leveal documentation of medicinal plants, their ingrediants and usage. To be effort has been made to evaluate plants used for medicare by the tribal people of Renla Gadda Thanda, Kodangal mandal, Mahabubnagar Dist, Telangana. Due to be deficient in of modern healthcare facilities and poor economic conditions, the tribal people of the Thanda fully depend on in the vicinity available medicinal plants for their healthcare needs. In the present report a total of 24 ethnomedicinal plants from 23 genus and 24 species occupied 18 families were recorded. The thorough information i.e., Usage, to be treated disorder, Parts used recorded. This is a first report from the Renlagadda Thanda of Kodangal mandal. The study area having wealthy in medicinal plants flora and tribal communities with latest usages. Documentation of traditional knowledge on medicinal plants from the village or thanda level is the elementary and necessary samples for novel medication.

Opis:
In the present study Limonia acidissima Groff. ethanolic leaves extract was used for the detection of its antidermatophytic assay. It results broad spectrum of antifungals and antibacterial. Where the antimycotic activity against Trichophyton rubrum, Trichophyton tonsurans, Trichophyton mentagrophytes, Microsporium gypseum, Candida albicans and four Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa were more pronounced. The effective antidermatophytic activity observed against M. gypseum, T. tonsurans, E. coli and B. subtilis. Minimum Inhibitory Concentration of all the test microbes was determined using broth dilution technique. MFC, MBC also standardized. Preliminary Phytochemical tests were carried for the revealing basics antimicrobial responsible molecules of secondary metabolites.

Opis:
Antimycotic activity of Petroleum ether and 98% methanolic young leaf soxhlet extract of Solanum nigrum (Solanaceae) was evaluated against dermatophytic fungi namely, Trichophyton rubrum, Trichophyton tonsurans, Trichophyton mentagrophytes, Microsporium gypseum, Candida albicans, and bacteria like, Staphylococcus aureus, Psudomonas aeruginosa, Bacillus subtilis, Escherichia coli. The maximum activity was observed in interpolar methanolic extract when compared to low polar petroleum ether extract. The minimum inhibitory concentration, minimum fungicidal concentration and minimum bactericidal concentration were determined against all the test strains. This study provides a basis for the isolation and purification of anti-dermatophytic compounds from the young leaves of S. nigrum.

Opis:
Pteridophytes and more specifically ferns represent a large but threatened group of plants which often serve as important environmental markers for pollution. Reports regarding stress responses in ferns are rare, apart from a few studies involving the ecological distribution and molecular marker studies. This work isolates a glutathione peroxidase enzyme from an aquatic fern widely distributed in fresh and polluted water bodies adjacent to sources of environmental polluted sources. Further computational analyses were performed to study the structure of the protein encoded by the open reading frame. Results indicate the presence of a large number of binding pockets which serve as important binding sites in the interactions with the cognate ligands.

Opis:
The present paper discusses the role of earthworms in recycling of sugar industrial wastes. The wastes generated from sugar industry are pressmud, bagasse, bagasse fly ash, sugar cane trash, sugar beet mud, sugar beet pulp, molasses etc. These wastes when mixed with other organic substrates become ideal mixtures for growth of earthworms. These wastes if stored in open field’s causes contamination in the environment and may cause several diseases in public health. But the governments have been unable to tackle the menace of solid waste pollution due to dearth of appropriate technologies, finance and space. Therefore, environment friendly and cost effective technologies for nutrient recycling or remediation of wastes are being advocated as an alternative means for conserving and replenishing natural resources of the ecosystems. Vermicomposting is one such technology that synergises microbial degradation with earthworm’s activity for reducing, reusing and recycling waste materials in a shorter span of time. Earthworm technology can convert sugar industrial wastes into valuable fertilizing material. The final product (vermicompost) produced during the process of vermicomposting is nutrient rich organic fertilizer with plant available nutrients such as nitrogen, potassium, calcium and phosphorus. In the present study an attempt has been made to document the role of earthworms in reuse of sugar industry waste.

Opis:
Biological method is considered as eco-friendly and reliable process for the synthesis of silver nanoparticles (AgNps) in the field of nanotechnology due to its tremendous applications in various fields. In this study we have isolated a total of twelve endophytic fungi from leaves of Curcuma longa (turmeric) and Catharanthus roseus out of which six endophytic fungi showed their ability to synthesized AgNps from silver nitrate (AgNO3) solution which splits into a positive silver ion (Ag+) and a negative nitrate ion (NO3 -) in order to turn the silver ions into solid silver (Agº). Of the six positive endophytic fungi VRD2 showed good and encouraging results and was identified as Penicillium spinulosum VRD2. UV-Visible Spectroscopy confirms the AgNps showing maximum peak at 425nm implying the bioreduction of AgNO3. Transmission Electron Microscopy (TEM) revealed the particle are spherical and well dispersed without agglomeration size ranging from 25- 30nm.

Opis:
HIV-1 or Human Immuno Deficiency Virus-1 is the main causative agent of Acquired Immuno Deficiency Syndrome (AIDS). Human host infected with HIV - 1 extensively harbours many viral variants but very little is known about the difference in pattern[17] of evolution of phylogenetic lineages of HIV-1 non recombinant, normal inter subtype recombinant and main two specific recombinant forms of HIV-1 i.e., Circulating Recombinant Forms (CRFs) and Unique Recombinant Forms (URFs). This study is mainly concerned with study of the difference in evolutionary lineages of non-recombinant and recombinant sequences of HIV-1 genome sequences and identification of geographically rich areas which has reported high degree of HIV-1 occurrence and variety. Total 1550 HIV-1 genome sequences were obtained from HIV Los Alamos Database. The sequences were aligned using MAFFT (Multiple Alignment using Fast Fourier Transform) web server tool. Alignment was carried out using 10 different set of alignment parameter values. After alignment the aligned file was used for constructing N-J phylogenetic tree using Clustal X2 tool. Phylogenetic analysis was performed keeping in mind the category to which the sequence belongs. Upon analysis it was observed that the clade containing the probable ancestor belongs remained constant in all cases of different alignment values. Non recombinant isolates, inter subtype recombinants, CRFs, URFs all followed different patterns of evolution. Non recombinant sequences were found geographically specific and subtype specific to some extent whereas, normal recombinants were subtype specific and less geographically specific. CRFs showed variation among the pattern of their evolution. At some instances the sequences occurred as sister taxa of non-recombinant or normal inter subtype recombinant sequences, while at some instances as sister taxa of other CRFs where they were geographically specific. Three CRFs existed as completely diverged sequences. URFs were four in number; two of them were Indian isolates of while other two were Japanese isolates. URFs were found to be totally geographically specific. Geography wise high rate of variation was observed in India and Japan as these two countries had sequences belonging to all of the above categories. Cameroon and South Africa have very large number isolates and a considerable amount of genetic variation among isolates but they lack URFs.
