Bait specificity in Hook and line fishery of River Ganga and associated conservation issues

61-72Recent survey in lower 1,110 km stretch of River Ganga regarding ‘hook and line’ fishery revealed that fishers apply their inherited indigenous knowledge for selection of bait to harvest finfish and shellfish from river water. A total number of 26 different types of baits under 07 categories were recorded. Six varieties of fish species and four types of insects are found to be prevalent for catching carnivorous fishes. Five specially modified indigenous types of bait moulded with fish attractants were also documented. Bait-fish species association in hook and line fishery of river Ganga is discussed. Feeding habits of the target fishes was compared with the type of baits employed. Conservation issues associated with hook and line fishery is highlighted along with possible remedial measures. Different varieties of hook & line fishery which are in operation in river Ganga are briefly described. Indigenous Traditional Knowledge (ITK) associated with hook & line fishery needs to be properly documented and preserved for developing and encouraging ‘sport fishery’ in River Ganga

Metal-mediated deformylation reactions: synthetic and biological avenues

No two ways about it: The title reaction is immensely important in synthesis and biology. Whereas biological systems oxygenate aldehydes to generate formate and alkanes or alkenes, synthetic deformylation reactions primarily rely on rapid oxidative addition into the C(O)H bond and subsequent rate‐determining extrusion of CO

Oxidative trifluoromethylation of unactivated olefins: an efficient and practical synthesis of α-trifluoromethyl-substituted ketones.

An economical approach to α-CF3-substituted ketones, which are important intermediates in synthetic and medicinal chemistry, employs olefins and the readily available Langlois reagent (CF3SO 2Na). The reaction is operationally simple, proceeds at room temperature, and exhibits an excellent tolerance toward a wide variety of functional groups. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.

Using microcontroller based solar power system for reliable power supply

This paper has been demonstrated by implementing renewable energy-based solar power for a reliable power supply controlled by the  Node MCU microcontroller. The microcontroller is controlled the system by programming. Here also use an inverter, Node MCU, Battery, Solar Charge Controller. The main task of this Scheme  is that when the sun reflects on this solar panel, it will charge and save its battery. Two AC loads will run from the battery to the inverter, which can control via the Internet. DC will be converted to AC through the inverter and load. The main objective of this research is to use solar sources for load control and monitoring through the Internet. &nbsp

Micro-structural investigations on oppositely charged mixed surfactant gels with potential dermal applications

Dicarboxylic amino acid-based surfactants (N-dodecyl derivatives of -aminomalonate, -aspartate, and -glutamate) in combination with hexadecyltrimethylammonium bromide (HTAB) form a variety of aggregates. Composition and concentration-dependent mixtures exhibit liquid crystal, gel, precipitate, and clear isotropic phases. Liquid crystalline patterns, formed by surfactant mixtures, were identified by polarizing optical microscopy. FE-SEM studies reveal the existence of surface morphologies of different mixed aggregates. Phase transition and associated weight loss were found to depend on the composition where thermotropic behaviours were revealed through combined differential scanning calorimetry and thermogravimetric studies. Systems comprising more than 60 mol% HTAB demonstrate shear-thinning behaviour. Gels cause insignificant toxicity to human peripheral lymphocytes and irritation to bare mouse skin; they do not display the symptoms of cutaneous irritation, neutrophilic invasion, and inflammation (erythema, edema, and skin thinning) as evidenced by cumulative irritancy index score. Gels also exhibit substantial antibacterial effects on Staphylococcus aureus, a potent causative agent of skin and soft tissue infections, suggesting its possible application as a vehicle for topical dermatological drug delivery.Validerad;2021;Nivå 2;2021-08-17 (alebob);Forskningsfinansiär: University Grants Commission (F.25-1/2014-15(BSR)/7-234/2009(BSR); F. 5-9/2015/DRS-II (SAP-II)); Department of Science and Technology, Govt. of India (SR/FST/CS-I/2017/7 (C))</p

A novel nanohybrid for cancer theranostics: folate sensitized Fe2O3 nanoparticles for colorectal cancer diagnosis and photodynamic therapy

Organic–inorganic nanohybrids are becoming popular for their potential biological applications, including diagnosis and treatment of cancerous cells. The motive of this study is to synthesise a nanohybrid for the diagnosis and therapy of colorectal cancer. Here we have developed a facile and cost-effective synthesis of folic acid (FA) templated Fe2O3 nanoparticles with excellent colloidal stability in water using a hydrothermal method for the theranostics applications. The attachment of FA to Fe2O3 was confirmed using various spectroscopic techniques including FTIR and picosecond resolved fluorescence studies. The nanohybrid (FA–Fe2O3) is a combination of two nontoxic ingredients FA and Fe2O3, showing remarkable photodynamic therapeutic (PDT) activity in human colorectal carcinoma cell lines (HCT 116) via generation of intracellular ROS. The light induced enhanced ROS activity of the nanohybrid causes significant nuclear DNA damage, as confirmed from the comet assay. Assessment of p53, Bax, Bcl2, cytochrome c (cyt c) protein expression and caspase 9/3 activity provides vivid evidence for cell death via an apoptotic pathway. In vitro magnetic resonance imaging (MRI) experiments in folate receptor (FR) overexpressed cancer cells (HCT 116) and FR deficient human embryonic kidney cells (HEK 293) reveal the target specificity of the nanohybrid towards cancer cells, and are thus pronounced MRI contrasting agents for the diagnosis of colorectal cance

An association study of severity of intellectual disability with peripheral biomarkers of disabled children in a rehabilitation home, Kolkata, India

International audienceThe current investigation has identified the biomarkers associated withseverity of disability and correlation among plethora of systemic,cellular and molecular parameters of intellectual disability (ID) in arehabilitation home. The background of study lies with the recentclinical evidences which identified complications in ID. Variousindicators from blood and peripheral system serve as potentialsurrogates for disability related changes in brain functions. IDsubjects (Male, age 10 ± 5 yrs, N = 45) were classified as mild,moderate and severe according to the severity of disability usingstandard psychometric analysis. Clinical parameters including stressbiomarkers, neurotransmitters, RBC morphology, expressions ofinflammatory proteins and neurotrophic factor were estimated from PBMC,RBC and serum. The lipid peroxidation of PBMC and RBC membranes, levelsof serum glutamate, serotonin, homocysteine, ROS, lactate and LDH-Aexpression increased significantly with severity of ID whereas changesin RBC membrane ?-actin, serum BDNF, TNF-? and IL-6 was found non-significant. Structural abnormalities of RBC were more in severelydisabled children compared to mildly affected ones. The oxidative stressremained a crucial factor with severity of disability. This is confirmednot only by RBC alterations but also with other cellular dysregulations.The present article extends unique insights of how severity ofdisability is correlated with various clinical, cellular and molecularmarkers of blood. This unique study primarily focuses on the strongpredictors of severity of disability and their associations via brain-blood axis
