Abstract:: ... Furan is a colorless toxic chemical produced in various food items during heat processing and in chemical industries. Both in vitro and in vivo studies have reported that it induces oxidative stress and endocrine disruption; however, limited data are available regarding the effects of furan on the reproduction of mammals. In the present study, an in vitro experiment was designed to investigate the ...

Abstract:: ... Furan is a colorless toxic organic compound that is produced during thermal degradation of natural food constituents, and is present in various processed foods such as coffee and processed baby foods. The present study investigated the endocrine disrupting potential of furan in Sprague Dawley male pups. On postnatal day 0 (PND 0), pups were divided into five groups. The control group received subc ...

Abstract:: ... In the present review, the ongoing researches about selenium research in fish nutrition have been comprehensively discussed. Selenium research is getting popularity in fish nutrition as it is required for the normal growth and proper physiological and biochemical functions in fish. Its deficiency or surplus amounts create severe problems in fish. It is available as inorganic form, organic form, an ...

Abstract:: ... The current study was conducted to determine the synergistic effects of dietary nano selenium (Nano Se) and vitamin C on growth, feeding, and physiological parameters of juvenile mahseer, Tor putitora. L-ascorbyl-2-polyphosphate (APP) was used as a source of vitamin C. Four semi-purified experimental diets were prepared. A basal diet kept without the supplementation of any micronutrient and the ot ...

Abstract:: ... Structural enrichment in the rearing environment, not only promotes fish welfare, but also affects several aspects of behavioural biology of fish in aquaculture. Here an attempt was made to use physical-enrichment to improve the behaviour of hatchery-reared fish. In this study, three groups of 15days old mahseer (Tor putitora) hatchlings were reared up to advanced fry stage in barren (without any ...

Abstract:: ... Four novel thiourea-based non-ionic surfactants, 1-decanoyl-3-phenylthiourea, 1-decanoyl-3-ethylthiourea, 1-butyl-3-decanoylthiourea and 1-cyclohexyl-3-decanoylthiourea were synthesized from readily available synthetic building blocks in high yield. The compounds were characterized by 1H NMR, 13C NMR, FTIR and UV–Visible spectrophotometry. These surfactants show very low solubility in water, and i ...
