Marine organisms as a source of natural matrix for bone tissue engineering
(Elsevier, 2019)It is a huge challenge to develop an effective regenerative approach which can be employed to restore diseased or defective part of the bone to its original anatomical and physiological function. Exploration of rich ... -
Immunoecology of the short neck clam Paphia malabarica (Chemnitz, 1782) in a tropical monsoon-influenced estuary
(Elsevier, 2019)Understanding the variability in organism's immunological response is crucial for predicting changes at population or community level. The present study investigated the immunoecology of a commercially valuable clam Paphia ... -
Sources of laminated sediments in the northeastern Arabian Sea off Pakistan and implications for sediment transport mechanisms during the late Holocene
(SAGE Publications, 2019)Laminated sediments of the continental slope off the Makran coast in the northern Arabian Sea are well-known climate archives and record productivity, as well as supply of material from land. Here, we studied sediment core ... -
Rare, metal micrometeorites from the Indian Ocean
(John Wiley & Sons, 2019)Metal in various forms is common in almost all meteorites but considerably rare among micrometeorites. We report here the discovery of two metal micrometeorites, i.e., (1) an awaruite grain similar to those found in the ... -
Immuno-modulation of settlement cues in the barnacle, Amphibalanus amphitrite: significance of circulating haemocytes
(Springer International Publishing, 2019)Gregarious settlement in barnacles has been attributed to chemical cues originating from the associated microorganisms, lectins, and settlement-inducing protein complex from arthropodin, a glycoprotein present in their ... -
Shewanella submarina sp. nov., a gammaproteobacterium isolated from marine water
(Microbiology Society, 2019)A curved-rod-shaped bacterium was isolated from a marine (100-m depth) water sample collected from Bay of Bengal, Visakhapatnam, India. Strain NIO-S14T, was Gram-stain-negative, motile and pale-yellow. NIO-S14T was able ... -
Numerical Modelling of Bed Shear Stress in OpenFOAM
(Springer, Singapore, 2019)In coastal zones, erosion is the major threat to the livelihood as it leads to the water inundation into the human premises. Sediment transport results in erosions causes morphological changes and also affects the coastal ... -
Evidence for underwater current activity on the upper slope of the carbonate platform off western India using multibeam bathymetry
(Current Science Association & Indian Academy of Sciences, 2019)This note presents multi-beam bathymetry data from the carbonate platform on the outer continental shelf of the northwestern margin of India at water depths between 60 and 90 m. This study analyze effect of underwater ... -
Recent Advances in C-H Bond Functionalization with Ruthenium-Based Catalysts
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2019)The past decades have witnessed rapid development in organic synthesis via catalysis, particularly the reactions through C-H bond functionalization. Transition metals such as Pd, Rh and Ru constitute a crucial catalyst in ... -
Extension of flood basalt on the northwestern continental margin of India
(Springer India, 2019)The Deccan Continental Flood Basalt (DCFB) in central western India is a large igneous province that covers almost one-sixth area of India. It is erupted in less than 1 million years during the magnetic chron 29 r (~ ... -
A 16-kyr Record of Ocean Circulation and Monsoon Intensification From the Central Bay of Bengal
(John Wiley & Sons, 2019)The monsoonal signal dominates most climate records from the Indian Ocean. As a consequence, conventional stable isotope tracers have not been effective at tracking ocean circulation in the Indian Ocean and distinguishing ... -
Tidal Energy Estimation of Potential Tidal Inlets Along the East Coast of India
(Springer, Singapore, 2019)The power consumption is increasing with modernization of infrastructure and with the depleting fossil fuels. The need to look for alternate sources of energy generation has already reached a peak. The production of power ... -
Nitrogen fixation and carbon uptake in a tropical estuarine system of Goa, western India
(Elsevier, 2019)Biological production in aquatic systems is often nitrogen limited. Nitrogen (N2) fixation is an important contributor to nitrogen requirement of phytoplankton not only in oligotrophic but also in nutrient-replete waters. ... -
Factors determining variations in viral abundance and viral production in a tropical estuary influenced by monsoonal cycles
(Elsevier, 2019)Viruses are the most abundant, dynamic, and ubiquitous components in the marine and estuarine environments. They outnumber prokaryotes in their abundance by at least one order of magnitude, but their relationship varies ... -
Future increase in extreme El Nino events under greenhouse warming increases Zika virus incidence in South America
(Nature Publishing Group, 2019)The Zika virus (ZIKV) was first found in Zika forest, Uganda in 1947. The disease appeared in the Americas, Northeast Brazil in May 2015. ZIKV propagated rapidly across the Americas and the World Health Organization (WHO) ... -
Marine-Derived Natural Products Inhibiting Specific Inflammatory Cytokines
(Elsevier, 2019)Inflammation is one of the earliest innate immune responses to tissue injury and various pathological stimuli. It is characterized by the recruitment and accumulation of immune cells in injured sites and by the production ... -
Ecological diversity of planktonic protists in spatial regimes of the Arabian Sea revealed through next-generation sequencing
(Elsevier, 2019)Eukaryotic microbes inhabiting diverse ecological niches are capable of mediating biogeochemical shifts. Here, we studied the distribution patterns of protistan community in oxygen-deficient sites in the Arabian Sea and ... -
Ecohydrographic control on the community structure and vertical distribution of pelagic Chaetognatha in the Red Sea
