Molecular characterization of CRY4 gene from bacillus thuringiensis
ISBN: 9783639375961 / Angielski / Miękka / 2011 / 352 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Synthetic insecticides have been effectively used during past several decades to control variety of insects and crop pests. The use of chemical insecticides has been greatly impeded due to development of physiological resistance in the vectors, environmental pollution and harmful effects on beneficial non-target animals. Therefore, the need of alternate, more effective and environment-friendly control agents became imperative.In this study,out of twenty two B.t isolates from the soil, six were found significantly toxic to 3rd instar larvae of Anopheles stephensi. One isolate SBS B.t 45, which...

Protozoan Fauna of Industrial Wastes and their Role in Bioremediation : Survey of Protozoan Fauna Surviving in Stress Conditions
ISBN: 9783639369069 / Angielski / Miękka / 2011 / 156 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Multiple metal resistant ciliates viz., Stylonychia mytilus, Euplotes mutabilis, Paramecium caudatum, Oxytricha fallax and Vorticella microstoma, isolated from industrial wastewater from Kasur tanneries were found to be resistant to various heavy metals viz., chromium, cadmium, copper, lead, mercury, zinc and nickel. These protozoans showed remarkable ability to survive under stress full conditions in the industrial waste water. These microorganisms cope with this heavy concentration of heavy metal ions by uptaking 85-95 % of metal ions from the culture medium. Some of these protozoans...

Physiological Importance of Cadmium Metallothionein Protein
ISBN: 9783845477190 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. TMCd1 is a stress inducible metallothionein (MT)gene that is expressed in Tetrahymena tropicalis lahorensis under cadmium metal stress. In the present study TMCd1 gene was expressed in E.coli and physiological importance of this Tetrahymena MT protein was evaluated. This stress inducible TMCd1 gene encodes 471 nucleotides, with TAA encoding glutamine (Gln) and TGA codes for a stop codon. To get the expression of full length protein the TMCd1 gene was mutated by site directed mutagenesis and TAA (at position 116) was converted to CAA (Gln). The MutTMCd1 gene was cloned in pET-41a expression...

Cadmium Metallothionein Gene of Paramecium
ISBN: 9783845471402 / Angielski / Miękka / 84 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Cadmium is a non essential trace metal, the increasing amount of which can be detrimental to the health. Once the cadmium level is elevated in the blood, it remains high even when its source is depleted. There is a need to remove the metal from the environment so our food, air or water is not contaminated by it. Metallothioneins (MTs) are metal binding proteins that are rich in cysteine residues constituting 30% of the total protein. The thiol groups bind to the metal ions. Different organisms such as bacteria, protozoa and mammals like humans have shown increased production of MTs with...

Functional Analysis of Promoter of cus Operon
ISBN: 9783846505113 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Copper is an essential trace metal for both prokaryotes and eukaryotes, and is associated with various metal enzymes which play many essential roles in the living system. But excess of the metal is very toxic and even lethal for living organisms. In microorganisms the intracellular level of copper is maintained by many genes working as an operon and induced by the presence of copper in their environment. One such operon is called cus operon regulated by cusRS two component system in Klebsiella pneumoniae. This cusS (sensory region) and cusR (regulatory region) autoregulate the expression of...

Plasmid Mediated Antibiotic Resistance in Gram-Negative Bacteria
ISBN: 9783639379204 / Angielski / Miękka / 2011 / 176 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The enteric pathogens isolated from diarrhoeal patients admitted to different hospitals of Azad Jammu & Kashmir were analyzed for antibiotic resistance and correlated with genetic elements in the bacteria.Salmonella spp. was the most frequently detected (35.8 %) enteropathogen followed by Escherichia coli (34.3 %), Shigella spp.(25.8 %) and Campylobacter spp. (4.1 %). The isolates of Shigella spp. showed highest resistance against penicillin, E. coli and Campylobacter spp. against carbenicillin, and Salmonella spp. were highly resistant to ampicillin.The most common pattern of antibiotic...

Development of Bioinsecticide
ISBN: 9783848442317 / Angielski / Miękka / 2012 / 168 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Synthetic insecticides has long been involved in causing fetal diseases to human beings as well as cattle. Importance of biological control of insect pests is aan environment friendly approach. With advances in biotechnology, recombinant bacteria and other organisms are being developed for better control of insect pests. Bacillus thuringiensis (BT) holds a central place among biocontrol agents. BT produces parasporal crystal proteins (Cry toxin) during sporulation phase of its growth. These toxins have defined spectra of toxicity to the target insects only, without doing any harm to friend...

Copper Metallothionein Gene of Tetrahymena
ISBN: 9783846516690 / Angielski / Miękka / 156 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Transition metals affect the viability of organisms and are fundamental and limiting factors at the same time, since they represent nutritionally important yet cytotoxic components in our environment. Both prokaryotes and eukaryotes carry cellular systems to maintain the metal homeostasis.Metallothioneins (MTs) are 6-7 kDa, ubiquitous, cytoplasmic, cysteine rich proteins, which have the capacity of high affinity binding to heavy metal ions. MTs play key role in essential as well as toxic heavy metal metabolism in the organisms. The ciliates tolerate elevated concentrations of metals, which...

Acute lymphoblastic leukemia (ALL) is a malignant disease caused by the abnormal growth and development of early non-granular white blood cells, or lymphoblasts. ALL occurs predominantly in children, peaking at 4 years of age. Interferons (IFNs) are the biological agents involved in the antiviral responses and the inhibition of tumor growth. In oncology, the IFNs are an important treatment options for a number of solid tumors and hematological malignancies. The IFN- 1gene consists of 840 bp and it lacks intron sequences. Seventy patients suffering from Childhood Acute Lymphoblastic Leukemia...
