Complete genome sequences of an Escherichia coli laboratory strain and trimethoprim-resistant (TMP32XR) mutant strains
We report the whole-genome sequences of an Escherichia coli laboratory wild-type strain and trimethoprim-resistant strains (two biological replicates, TMP32XR1 and TMP32XR2). Compared to the U00096.3 strain, a widely used strain in laboratory experiments, the laboratory wild-type strain and the drug-resistant strains evolved from this (TMP32XR1 and TMP32XR2) are 13, 24, and 37 bp longer, respectively
Is the Scyphozoan jellyfish Lychnorhiza malayensis symbiotically associated with the crucifix crab Charybdis feriatus?
Scyphozoan jellyfish (Medusae), the
gelatinous invertebrate group, plays a
vital role in the global oceanic and
coastal ecosystems. By virtue of their
floating nature, and horizontal and vertical
spread in the water column, they are
known to have varied associations with
other invertebrates and teleosts, which
make them an integral part of the marine
ecosystem
Marine ornamental fish culture: Means for economic growth
The marine ornamental fish trade is a sunrise industry that has been expanding in recent years and has
grown into a multimillion-dollar enterprise mainly due to the emergence of technologies for captive
breeding of fishes, modern aquarium gadgets, setting and maintenance of miniature reef aquaria. Aquarium
keeping is amongst the most popular of hobbies with millions of enthusiasts worldwide and the trade of
marine ornamentals has been expanding in recent years and has grown into a multimillion-dollar enterprise.
The recent emergence of modern aquarium gadgets and technologies for setting and maintenance of
miniature reef aquaria made aquarium keeping much easier than previous. Since the marine ornamental
trade is operated throughout the tropics, the global marine ornamental trade is estimated at US$ 200-330
million. India is endowed with a vast resource potential of marine ornamentals distributed in the coral
seas and rocky coasts with patchy coral formations. In the context of the expanding global scenario and
the increasing demand for domestic trade, it appears very lucrative for India to venture into this industr
Some observations on the beaked sea snake Enhydrina schistosa (Daudin, 1803) in the mudbank area, off Alapuzha, Kerala, southwest coast of India
Hook-nosed sea snake or beaked snake, Enhydrina schistosa
were caught during experimental fishing operations in the
mudbank region along central Kerala Coast at depths
ranging from 6 to 12 m. The sea snakes were found to
form aggregations of 5 to 6 numbers and were able to
tolerate highly turbid waters. The catfish Arius jella and the
puffer fish Lagocephalus inermis were the dominant prey
items. mudbanks are unusually calm areas which form
along the Kerala coast during the monsoon. The inshore
waters including the mudbanks are intense fishing areas of
non mechanized crafts during the monsoon. The presence
of venomous sea snakes is precarious and there is a need
to give awareness programme for the fishers about this
danger
Meta-analysis of host response networks identifies a common core in tuberculosis
Tuberculosis remains a major global health challenge worldwide, causing more than a million deaths annually. To determine newer methods for detecting and combating the disease, it is necessary to characterise global host responses to infection. Several high throughput omics studies have provided a rich resource including a list of several genes differentially regulated in tuberculosis. An integrated analysis of these studies is necessary to identify a unified response to the infection. Such data integration is met with several challenges owing to platform dependency, patient heterogeneity, and variability in the extent of infection, resulting in little overlap among different datasets. Network-based approaches offer newer alternatives to integrate and compare diverse data. In this study, we describe a meta-analysis of hostтАЩs whole blood transcriptomic profiles that were integrated into a genome-scale proteinтАУprotein interaction network to generate response networks in active tuberculosis, and monitor their behaviour over treatment. We report the emergence of a highly active common core in disease, showing partial reversals upon treatment. The core comprises 380 genes in which STAT1, phospholipid scramblase 1 (PLSCR1), C1QB, OAS1, GBP2 and PSMB9 are prominent hubs. This network captures the interplay between several biological processes including pro-inflammatory responses, apoptosis, complement signalling, cytoskeletal rearrangement, and enhanced cytokine and chemokine signalling. The common core is specific to tuberculosis, and was validated on an independent dataset from an Indian cohort. A network-based approach thus enables the identification of common regulators that characterise the molecular response to infection, providing a platform-independent foundation to leverage maximum insights from available clinical data

Seed production of Clown Fishes
Ornamental fish production for the aquarium industry is a multimillion dollar industry
in the world. Aquarium keeping is amongst the most popular of hobbies with millions of
enthusiasts worldwide. Although most fish kept in aquariums are from freshwater, the
acquisitions of marine ornamental fish has greatly increased in recent years and are also
popularized through childrenтАЩs movies by starring charismatic colorful fishes and other
creatures. Recent advances in fish husbandry and aquarium gadgets and technology have
further facilitated the hobby. The vast array of organisms that make up the generic
ornamental aquarium fish trade is staggering. In India, marine ornamental fish trade is an
emerging field during the last two decades and day by day the industry in advancing. As the
industry is growing, it also foster additional sideline business such as aquarium making,
aquatic plants and live food production, grow- out culture there by provide job opportunity
and livelihood option
