We present and describe the fairy shrimp Streptocephalus sahyadriensis sp. nov. from the Western Ghats of India. This species is most similar to S. simplex Gurney, 1906 and S. dichotomus Baird, 1860 sharing similar basic antennal appendage morphology. However, S. sahyadriensis sp. nov. differs in the form of the ornamentation on the peduncle and the arrangement and form of spines on the antennal appendage. The three species also have different egg surface morphologies. The Asian species of Streptocephalus are discussed and a key to species is provided. Copyright © 2014 Magnolia Press.

Megymenum distanti, a new species of the dinidorid subfamily Megymeninae, is described from India and is compared with M. affine and M. brevicorne. It is the sixth species of this genus known from India. Remarks on the habitat, where the type material was collected, photographs of the host plant and a brief description of all instars are provided. This species is of a different color as an adult and as nymphs, a situation which is unusual. Copyright © 2012 Magnolia Press.

Molecular Phylogenetics and Evolution | Year: 2013

We used a combined analysis of one nuclear (28S rDNA) and three mitochondrial markers (COI, 12S rDNA, 16S rDNA) to infer the molecular phylogeny of the Notostraca, represented by samples from the six continents that are inhabited by this group of branchiopod crustaceans. Our results confirm the monophyly of both extant notostracan genera Triops and Lepidurus with good support in model based and maximum parsimony analyses. We used branchiopod fossils as a calibration to infer divergence times among notostracan lineages and accounted for rate heterogeneity among lineages by applying relaxed-clock models. Our divergence date estimates indicate an initial diversification into the genera Triops and Lepidurus in the Mesozoic, most likely at a minimum age of 152.3-233.5. Ma, i.e., in the Triassic or Jurassic. Implications for the interpretation of fossils and the evolution of notostracan morphology are discussed. We further use the divergence date estimates to formulate a biogeographic hypothesis that explains distributions of extant lineages predominantly by overland dispersal routes.We identified an additional hitherto unrecognised highly diverged lineage within Lepidurus apus lubbocki and three additional previously unknown major lineages within Triops. Within T. granarius we found deep differentiation, with representatives distributed among three major phylogenetic lineages. One of these major lineages comprises T. cancriformis, the T. mauritanicus species group and two hitherto unrecognised T. granarius lineages. Samples that were morphologically identified as T. granarius diverged from the most basal nodes within this major lineage, and divergence dates suggested an approximate age of 23.7-49.6. Ma for T. cancriformis, indicating the need for a taxonomic revision of Triassic and Permian fossils that are currently attributed to the extant T. cancriformis. We thus elevate T. cancriformis minor to full species status as Triops minor Trusheim, 1938 and include in this species the additional Upper Triassic samples that were attributed to T. cancriformis. We further elevate T. cancriformis permiensis to full species status as Triops permiensis Gand et al., 1997. © 2013 Elsevier Inc.

An updated inventory of large branchiopods of the Western Maharashtra state, India is presented for the first time. Employing current identification keys, we have detailed the egg morphology of Eulimnadia indocylindrova, which shares some similarities with E. geayi from South America and E. alluaudi from Madagascar, based on these egg characters. A thorough re-description of few morphological traits of the same species is also presented. We also have described the female of a Cyzicus species seen rarely from the studied region. Distributional comments on few species are also reported. Copyright © 2015 Magnolia Press.

Nanotechnology is a field of science which involves the synthesis and applications of nanoparticles. Silver nanoparticles (AgNp) have applications in various fields due to their unique optical, physical, electrical and medicinal properties. In this study, silver nanoparticles were synthesized by biophysical method. Silver nanoparticles were characterized by using UV-Visible absorption spectroscopy (Surface Plasmon absorption at 418-420 nm), Energy Dispersive Spectroscopy (EDX), Scanning Electron Microscopy (SEM) and X- ray diffraction (XRD). The cytotoxic effect of silver nanoparticles on acute myeloid leukemia cell line (THP - 1 cell line) was studied in vitro. The activity of chemotherapeutic drugs Cyclophosphamide and Busulfan was enhanced in presence of silver nanoparticles whereas Mercaptopurine was found to be more effective when used individually against the THP- 1 cell line.

A simple method for synthesis of biologically stabilized silver nanoparticles was developed using the seed extract of Argyeria nervosa. The nanoparticles synthesized using A. nervosa were characterized by UV-Vis spectrophotometry, X-Ray Diffraction, SEM-EDS and FTIR. The antibacterial and antifungal activity of silver nanoparticles was assessed against Staphylococcus aureus, Bacillus subtilis, Aspergillus niger, Escherichia coli and Pichia pastoris. The silver nanoparticles synthesized thus demonstrated potent antagonistic activity against bacteria and fungi which possess potential applications in medicine and pharmaceutical fields.

The study is described in which the ethanol and methanol extracts from Acacia nilotica L. bark were evaluated for their possible antibacterial and antioxidant activity. Preliminary phytochemical analysis of ethanolic and methanolic extracts was carried out by using simple chemical tests. Total phenolic content of both the extracts was determined by Folin-Lowry method. Ethanolic extract of Acacia nilotica L. was found to contain 307.54 ± 2.67 mg GAE/gm dry weight of phenolics and 496.42 ± 6.89 mg QE/gm dry weight of flavonoids. Antioxidant activity of both the extracts was evaluated by phosphomolybdenum method and DPPH radical scavenging method. Ethanolic extract demonstrated the highest DPPH radical scavenging activity of 71.8 ± 0.18 % at 1000μg/ml concentration. Both the extracts showed broad spectrum antibacterial activity. The study suggests that the plant has promising applications in the development of phytomedicines with antibacterial and antioxidant properties.

The exponential growth of the Internet and online activity raise a number of cyber world business issues and legal questions. The power of the Web to reach the world carries with it a variety of legal issues, often related to intellectual property concerns, copyright, trademark, privacy and security etc., particularly in the context of doing business on the Internet. Authorities seeking to apply their laws in traditional ways or to expand legal control over international links face many challenges due to the global nature of the Internet. Today, there are more questions on cyber law than answers. Also it poses a challenge for technology and the criminal justice system. There is general misunderstanding that the entire Indian cyber law is encapsulated in IT Act2000. Where as IT Act2000 defines and punishes only a few cyber crimes. Therefore, it is necessary to know the relevant aspects of several other laws and their interplay with IT Act which directly or indirectly affect transactions in the cyber world since the cyber crimes such as hacking planting computer viruses and online financial frauds have the potential of shaking economics of the country. This paper provides an overview of the cyber crimes and cyber-legal issues related with IT Act 2000 in INDIA and challenges in eCommerce.

The aim of present study was to evaluate antioxidant and antibacterial activity of Vitex negundo L. and Tabernaemontana divaricata L.Methanolic extract of V. negundo L. was found to contain142.96 ± 6.73 mg GAE/gm dry weight of phenolicsand167.88 ± 4.80 mg QE /gm dry weightflavonoids. The leaf extracts of V. negundo L.demonstrated higher antioxidant activity as compared to T. divaricataL. Both the plant extracts showed broad spectrum antibacterial activity. The cytotoxic activity of theextracts of V. negundo L. and T. divaricata L. were assessed on THP-1 leukemia cell line using MTT assay and both the plants demonstrated cancer cell inhibitory activity.Both these shrubs have potential applications in pharmaceutical industry and medicine due to their phytoconstituents, antioxidants, antibacterial and anticancer activities.
