In this context protection of fish is necessary for both ecological and economic reasons because fish are the key species in the aquatic ecosystem and they represent a major dietary protein source for a significant proportion of human population. Practical solutions to the water quality deterioration and management of fish resource in the polluted waters may come from the detailed and comparative studies on the natural detoxication mechanisms of aquatic organisms. There is an urgent need for the creation of detailed nucleotide and protein sequence database of the key enzymes and other molecular systems involved in detoxication. This will further expand the explorative horizons of environmental toxicology to embrace into its fold the toxicological genomics and ecosystem engineering. Any suggestion, exchange of idea and comment in this regard is most valuable. To leave a message to author please visit the page https://sites.google.com/site/drroysonali/ ····· 1036119968

Hand-made cloning (HMC) is an effective alternative to the conventional micromanipulator based technique in some domestic species. The present study was carried out for the establishment of an effective enucleation method, for selection of suitable somatic cell as nuclear donor and for development of an optimum culture system for in vitro culture of zona free cloned embryos of goat (Capra hircus). An efficient chemically assisted enucleation procedure was established for goat HMC. Treatment of donor cells with roscovitine resulted in better hand-made cloned blastocyst yield. Production of hand-made cloned goat embryos was better with electric pulse activation than Ca ionophore activation. A highly effective culture system for the development of hand-made cloned goat embryos was established. Furthermore, fetal fibroblast cells proved to be better nuclear donor than fresh cumulus cells or cultured cumulus cells. ····· 1036119904

It is suggested that the resultant metabolic imbalance led to more leakage of electrons from the mitochondrial electron transport chain than normal, and through lipid peroxidation increased levels of hydroperoxides. In addition, dehydration and hydrated storage may depress the activities of free radical processing enzymes, SOD, CAT and GR and levels of antioxidant, AsA. This phenomenon was less pronounced during rapid, in comparison to slow, desiccation and moist storage. However, it appears that the above biochemical events are overtaken by physical damage at higher water contents in the highly recalcitrant seeds. It was concluded that the differential effects of the drying rate and wet storage on responses of desiccation-sensitive seeds varies with tissue, harvest, species and the degree of desiccation sensitivity. ····· 1036119842

There is a vast area between Tuticorin and Kanyakumari which has never been explored so far even its comes under Marine Biosphere Reserve and includes thousands of fishermen who depend on fishery for their daily livelihood. The present pilot scale study was conducted in kudankulam coast within a 4 km radius in marine zone from kudankulam nuclear power project which confirmed that southern part of the Gulf of Mannar can also provide plentiful resources including rich ecologically sensitive habitats like seagrass and coral ecosystem. The resources in this region may not be similar to the northern part between Rameswaram and Tuticorin, but they are potent enough to provide a good source for fishery. Since various developmental activities like the nuclear power plant which is to be operated in the near future, it is very important to have a detailed baseline data on the seagrass, corals and associated organisms of this coastal region.With this baseline data the number of species in the Gulf of Mannar Biosphere Reserve can be estimated in the future studies. ····· 1036119805

These functions can be classified as mediators in the interaction of the plant with its environment, such as plant insect, plant microorganism and plant plant interactions. Secondary metabolism also plays a role in plant reproduction, for example, in attracting pollinators and in male fertility. Secondary metabolites determine important aspects of human food quality (taste, colour and smell), and plant pigments are important for the diversity of ornamental plants and flowers. Moreover, several plant secondary metabolites are used for the production of medicines, dyes, insecticides, flavours and fragrances. Secondary metabolism is thus an interesting target for plant breeding. ····· 1036119770

It is important for the survival of all living things. Without a mechanism for reproduction, life would come to an end. Human reproduction is a form of sexual reproduction resulting in the conception of a child, typically involving sexual intercourse between man and woman. During intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman`s ovum by the man`s sperm, which after a gestation period is followed by childbirth. Many teachers are afraid of discussing reproduction and endocrinology, but if presented as a factual lesson it is easy for the students to understand the principles without the standard giggles.Our goal for writing these lecture notes is to help future biologists to gain a basic understanding of reproduction and endocrinology so that they can handle the subject as per their need.

Superoxide anion is critical for host defense against fungal and bacterial pathogens and efficient immune responses however, uncontrolled monocyte-derived O2.- may contribute to chronic inflammation and tissue injury. We have previously identified several pathways that regulate the activity of NADPH oxidase in human monocytes however, the receptor(s) responsible for the activation of NADPH oxidase in primary human monocytes have not yet been determined. This dissertation shows that pattern recognition receptors, namely Dectin-1, is essential for regulating NADPH oxidase activity in Zymosan-activated human monocytes.

Cell lines, canine mammary tumor tissues and human oral cancer tissues were processed for protein extraction. The concentration of the protein was determined by Bradford s method and used for Telomere Repeat Amplification Protocol (TRAP). The amplified products were electrophoresed on 20% non-denaturing polyacrylamide gel along with 10bp ladder. The presence of 6 base repeats starting from 50 nucleotides is considered as positive. Then the TRAP products were immobilized on to streptavidin coated microtitre plates via biotin - streptavidin interaction and then detected by anti-DNP antibody conjugated with horse radish peroxidase. The absorbance was measured at 450 nm and at 690 nm. Samples was regarded as telomerase positive if A is greater than 0.2, where A: net increase of absorbance for the sample = A sample A heat-treated sample.Telomerase serves as an efficient biomarker for diagnosis of tumor and cell lines serves as a model system to investigate the efficacy of telomerase targeted therapeutics for cancer. ····· 1036118779

For the first time, we reported two missense mutations in Pyruvate kinase M2 isozyme (H391Y and K422R) from the cells of Bloom syndrome patients, prone to develop cancer. Results showed that despite the presence of mutations in the inter-subunit contact domain, the K422R and H391Y mutant proteins maintained their homotetrameric structure, similar to the wild-type protein, but showed a loss of activity by 75 and 20%, respectively. Interestingly, H391Y showed a 6-fold increase in affinity for its substrate phosphoenolpyruvate and behaved like a non-allosteric protein with compromised cooperative binding. The co-expression of homotetrameric wild type and mutant PKM2 in the cellular milieu resulted in the interaction between the two at the monomer level, which was substantiated further by in vitro experiments. Interestingly, in a unique observation, hetero-oligomeric populations of PKM2 with an altered activity and affinity led to an increased rate of polyploidy i.e genomic instability. ····· 1036118638· 1 · ::::: · 29 ·· 30 ·· 31 ·· 32 ·· 33 ·· 34 ·· 35 · ::::: · 36 ·
