Studies on the macrobenthic community of Cochin backwaters with special reference to culture of Eriopisa chilkensis (Gammaridae-Amphipoda)

This thesis Entitled studies on the macrobenthic community of cochin backwaters with special reference to culture of eriopisa chilkensis (Gammaridae- amphipoda).Benthic organisms are usually studied for environmental impact assessment, pollution control and resource conservation. The benthic monitoring component has three major objectives: 1) characterize the benthic communities to assess the estuarine health, 2) determine seasonal and spatial variability in benthic communities, and 3) detect changes in the estuarine community through examination of changes in abundances of specific indicator taxa and other standard benthic indices.Cochin backwaters situated at the tip of the northern Vembanad lake is a tropical positive estuarine system. The backwaters of Kerala support as much biological productivity and diversity as tropical rain forest and are responsible for the rich fishery potential of Kerala. Backwaters also act as nursery grounds for commercially important prawns and fishes.The thesis has been subdivided into seven chapters. The first chapter gives a general introduction about the topic and also highlights the scope and purpose of the study. The second chapter covers the methodology adopted for the collection and analysis of water quality parameters, sediment and the macrobenthic fauna.Chapter 3 deals with hydrographic features, sediment characteristics and the spatial variation and abundance of macrobenthic fauna in the Cochin estuary.Chapter 4 explains the impact of organic enrichment on macrobenthic popUlation in the Cochin estuary and includes the comparison of the present data with the earlier work in this region.Chapter 5 deals with seasonal variability in abundance of macrobenthic species in the estuary. The study was conducted from 9 stations during three seasons (pre-monsoon, monsoon and post-monsoon) in 2003.Chapter 6 deals with Life history and Population Dynamics of Eriopisa chilkensis Chilton (Gammaridae-Amphipoda). The life cycle of the gammarid amphipod Eriopisa chilkensis from the Cochin estuary, south west coast of India was studied for the first time under laboratory conditions.

Development of plant tissue culture of Plumbago rosea Linn. for enhanced production of secondary metabolites

P rosea syn. Indica belong to the family of plumbaginaceae, is an important medicinal plant, cultivated widely in India. The roots of these plant are generally used for medicinal purposes mainly as diuretic, germicidal, vessicant, and abortifacient. It is also used for anaemia, diarrhea, leprosy and common wart. The bark of the root contains orange yellow pigment named plumbagin, a crystalline substance, belongs to the class of naphthoquinone. Its chemical structure is 5-hydroxy 2-methyl 1,4naphthoquinone. Apart from P rosea, P zeylanica, P europea, Drosera and Drosophyllum also contains plumbagin. The most exploited source of plumbagin is, of course, P. rosea roots. The roots contain O.9mg/ g D.Wt. of plumbagin in the roots. These plants grow very slowly and the roots suitable for plumbagin extraction can be obtained only after several years of growth. The productivity of the plant is also rather poor. The focus of the present study was to develop alternative strategies to obtain plumbagin. The tissue culture of P rosea for micropropagation has been studied

Primary hemocyte culture of Penaeus monodon as an in vitro model for white spot syndrome virus titration, viral and immune related gene expression and cytotoxicity assays

Immortal cell lines have not yet been reported from Penaeus monodon, which delimits the prospects of investigating the associated viral pathogens especially white spot syndrome virus (WSSV). In this context, a method of developing primary hemocyte culture from this crustacean has been standardized by employing modified double strength Leibovitz-15 (L-15) growth medium supplemented with 2% glucose, MEM vitamins (1 ), tryptose phosphate broth (2.95 g l 1), 20% FBS, N-phenylthiourea (0.2 mM), 0.06 lgml 1 chloramphenicol, 100 lgml 1 streptomycin and 100 IU ml 1 penicillin and hemolymph drawn from shrimp grown under a bio-secured recirculating aquaculture system (RAS). In this medium the hemocytes remained viable up to 8 days. 5-Bromo-20-deoxyuridine (BrdU) labeling assay revealed its incorporation in 22 ± 7% of cells at 24 h. Susceptibility of the cells to WSSV was confirmed by immunofluoresence assay using a monoclonal antibody against 28 kDa envelope protein of WSSV. A convenient method for determining virus titer as MTT50/ml was standardized employing the primary hemocyte culture. Expression of viral genes and cellular immune genes were also investigated. The cell culture could be demonstrated for determining toxicity of a management chemical (benzalkonium chloride) by determining its IC50. The primary hemocyte culture could serve as a model for WSSV titration and viral and cellular immune related gene expression and also for investigations on cytotoxicity of aquaculture drugs and chemicals

Application of primary haemocyte culture of Penaeus monodon in the assessment of cytotoxicity and genotoxicity of heavy metals and pesticides

Lack of shrimp cell lines has hindered the study of pollutants which adversely affects shrimp health and its export value. In this context a primary haemocyte culture developed from Penaeus monodon was employed for assessing the cytotoxicity and genotoxicity of two heavy metal compounds, cadmium chloride and mercuric chloride and two organophosphate insecticides, malathion and monocrotophos. Using MTT assay 12 h IC50 values calculated were 31.09 16.27 mM and 5.52 1.16 mM for cadmium chloride and mercuric chloride and 59.94 52.30 mg l 1 and 186.76 77.00 mg l 1 for malathion and monocrotophos respectively. Employing Comet assay, DNA damage inflicted by these pollutants on haemocytes were evaluated and the pollutants induced DNA damage in >60% of the cells. The study suggested that haemocyte culture could be used as a tool for quantifying cytotoxicity and genotoxicity of aquaculture drugs, management chemicals and pollutants

Made in “Polish village” – modern ethno-design vs. traditional culture of Polish countryside

Tradycyjna polska wieś – kolorowa, wesoła, zintegrowana z naturą i rządząca się swoimi prawami to zbiorowy mit, odległy w czasie. To klasyczny temat wielu poszukiwań etnografi cznych – terenowych, naukowych opracowań i porównań. We współczesnym świecie mamy do czynienia jedynie z wybranymi elementami – tradycjami jeszcze żywymi lub przetworzonymi i dostosowanymi do wymogów współczesnego odbiorcy – turysty, ale także artysty i projektanta. Obecne zainteresowanie polską sztuką ludową i rzemiosłem to kolejna fala mody folkowej. Ten ogólnoeuropejski trend, poszukujący w kulturze egalitarnej natchnienia i inspiracji swój początek bierze w I połowie XIX wieku. W polskiej sztuce dekoracyjnej (wzornictwie przemysłowym) także nastąpił powrót do źródeł, a w ludowości i wiejskości doszukiwano się narodowego ducha, inspiracją dla polskich artystów był angielski Ruch Arts and Craft, a w ich projektach widoczne były echa fi lozofi i Johna Ruskina oraz Williama Morrisa m. in. odrzucających masową produkcję, mającą wg nich zły wpływ na jakość produkowanych przedmiotów, jednocześnie na piedestał wynoszących umiejętności rękodzielnicze i rzemieślnicze. Po okresie PRLu utożsamianym głównie z funkcjonowaniem Cepelii i sprowadzeniem produktów inspirowanych ludowością do roli masowych dekoracji, stanowiących często synonim kiczu, powróciła moda na polskie rękodzieło, tradycyjną sztukę ludową oraz na inspiracje wypływające z obserwowania wiejskiego stylu życia. Współczesne poszukiwania polskich twórców w obszarze tworzących w ramach nurtu zwanego etnodizajnem przebiegają dwutorowo. Z jednej strony to inspiracja tylko przejawami ludowości, jej konkretnymi wytworami, które stanowią głównie dekorację dla współczesnych rozwiązań formalnych i technologicznych. Jednak coraz silniejszy jest drugi nurt,starający się wniknąć głębiej, którego celem jest zrozumienie istoty tradycyjnej kultury ludowej polskiej wsi. To inspiracja wiejskim stylem życia, wraz z jego zaletami i wadami, to wreszcie inspiracja zmieniającym się krajobrazem kulturowym i poszukiwanie nowych rozwiązań, dzięki którym odbiorca zbliży się do natury. Projekty zaliczane do nurtu etnodizajnu cechuje przede wszystkim różnorodność wykorzystanych materiałów (tradycyjnych i nowoczesnych), sposób ich przetworzenia, zachowanie pierwotnej funkcji lub nadanie nowej. Większość tych projektów sytuuje się też w nurcie eko-artu, sztuki nawiązującej do natury, z wykorzystaniem ekologicznych materiałów. Jest więc etnodizajn XXI kontynuacją ideologii stworzonej już w wieku XIX – przeciwstawieniem dla przemysłu, technicyzacji i umasowienia. A dla współczesnego człowieka – miejskiego – może być etnodizajn powrotem do źródeł.

In vitro fermentation of oat bran obtained by debranning with a mixed culture of human fecal bacteria

The prebiotic potential of oat samples was investigated by in vitro shaker-flask anaerobic fermentations with human fecal cultures. The oat bran fraction was obtained by debranning and was compared with other carbon sources such as whole oat flour, glucose, and fructo-oligosaccharide. The oat bran fraction showed a decrease in culturable anaerobes and clostridia and an increase in bifidobacteria and lactobacilli populations. A similar pattern was observed in fructo-oligosaccharide. Butyrate production was higher in oat bran compared to glucose and similar to that in fructo-oligosaccharide. Production of propionate was higher in the two oat media than in fructo-oligosaccharide and glucose, which can be used as energy source by the liver. This study suggests that the oat bran fraction obtained by debranning is digested by the gut ecosystem and increases the population of beneficial bacteria in the indigenous gut microbiota. This medium also provides an energy source preferred by colonocytes when it is metabolized by the gut flora.
