We propose a simple web search engine based method for collecting approximated historical data of temporally changing social adaptive networks, which are rather difficult to obtain experimentally in conventional research methods. In the proposed method, a search query string is combined with additional keywords that specify inclusion/exclusion of specific(More)
The diversity of culturable, aerobic and heterotrophic Bacillus and Bacillus-derived genera (BBDG) was investigated in various extreme environments (including thermal springs, cold deserts, mangroves, salt lakes, arid regions, salt pans and acidic soils) of India. Heat treatment followed by enrichment in different media led to a total of 893 bacterial(More)
Coconut, cocoa and arecanut are commercial plantation crops that play a vital role in the Indian economy while sustaining the livelihood of more than 10 million Indians. According to 2012 Food and Agricultural organization's report, India is the third largest producer of coconut and it dominates the production of arecanut worldwide. In this study, three(More)
Information gathered with advanced nucleotide sequencing technologies, small molecule detection systems and computational biology is revealing that a community of microbes and their genes, now termed "the microbiome," located in gut and rhizosphere, is responsible for maintaining the health of human beings and plants, respectively. Within the complete(More)
Two unicellular cyanobacteria Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942 showed contrasting responses to chromate stress with EC50 of 12 ± 2 and 150 ± 15 μM potassium dichromate respectively. There was no depletion of chromate in growth medium in both the cases. Using labeled chromate, very low accumulation (<1 nmol/108 cells) was(More)
Mycorrhizal fungi are widespread in agricultural systems and are especially relevant for organic agriculture. A study was conducted to assess diversity in the arbuscular mycorrhizal (AM) fungi associated with coconut and arecanut intercropping systems of Kasaragod and Thiruvananthapuram districts of Kerala. Mycorrhizal parameters like spore density, root(More)
BACKGROUND Postoperative inflammation continues to be a cause of patient discomfort, delayed recovery, and in some cases, suboptimal visual results. Topical nonsteroidal anti-inflammatory drugs (NSAIDs) and steroid are commonly used in the management and prevention of noninfectious ocular inflammation following cataract surgery. AIMS The aim was to study(More)
Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is rare and an important cause of hypoglycemia in neonates. It can lead to brain damage or death secondary to severe hypoglycemia. We present the anesthetic management in a diagnosed case of PHHI in an 8-day-old male neonate for total pancreatectomy.
Degree of arbuscular mycorrhizal (AM) association and its diversity were investigated in the coconut palm (Cocos nucifera L.) cultivated in crop mixed system under rain-fed condition in a highly productive humid tropical zone in Malappuram district of Kerala, India. Forty AM species belonging to ten genera viz. Acaulospora, Claroideoglomus, Dentiscutata,(More)
Aleurone tissue is known for its function of secreting a number of hydrolytic enzymes including α-amylases, nucleases and proteases in response to gibberellic acid (GA). The effect of GA on aleurone tissue function was studied in Triticum dicoccum including a tall variety, its semi-dwarf mutant and a semi-dwarf variety carrying RhtB1b allele, using isolated(More)
