Production of Phosphatase by Phosphate Solubilizing Improved Fungal Strains
Abstract: Phosphate solubilizing micro-organisms were isolated from rhizosphere soils of rice fields around Mannachanalur area, Tiruchirappali district of Tamilnadu. The isolated fungal cultures were identified as Aspergillus niger, Aspergillus fumigatus and Penicillium sp. The efficacy of Phosphatase activity of fungal strains was carried out. The fungal strains were subjected to random mutational studies such as UV and chemical mutation. The Phosphatase assay was carried out after random mutagenesis using wild and …

New Wine in Old Wineskin: Progressive Development of Genomic Editing in Bombyx mori
Abstract: The Bombyx mori insect emerging from lepidopteran family is exploited as an important remunerative specie, vis-a-vis as a model organism for scientific findings. It is unequivocally a primal insect model in which genomic altering tool was used to establish a gene function in vitro. A significant milestone in Bombyx genetics is evidenced by contemporary advancement in germline transformation and whole-genome sequencing, producing genetically engineered silkworms (new wine in an old …

Importance of Engineering of the Protein Molecules: A Review
Abstract: Engineering of the proteins is a powerful tool for production of the novel proteins that serve as catalysts to induce selective chemical and biological transformations that would not otherwise be possible. The methods of rational and random (methods entailing evolution, selection and the screening) are employed for the purpose to alter the specificity of the substarte profiles of selectivity through mutating the enzymes. The proteins identified through these techniques are …

Toxicological Profiling and Safety Assessment of NASAT 2.0: A Conceptual Framework for Adaptive Nanoparticle Therapy in Rabies
Abstract: Rabies, caused by the highly neurotropic Rabies lyssavirus, remains one of the most enigmatic and universally lethal infectious diseases known to modern medicine. Once clinical symptoms manifest following successful neuroinvasion, the fatality rate approaches absolute certainty (approximately 99.9%), a staggering statistic that has remained largely unchallenged despite massive, concurrent advances in modern virology, critical care medicine, and cellular immunology. Current late-stage therapeutic protocols, most notably the widely debated Milwaukee Protocol, …

Role of Nitric Oxide in Platelets of Breast Carcinoma
Abstract: Breast cancer is a disease of multifactorial origin; it is seen frequently in women of older age, having family history, affluent society, late age of marriage and first childbirth, early menarche, late menopause, and nulliparity. Oxidative stress results when balance between reactive oxygen species (ROS) production and antioxidant defence is lost which result in mutations, sister chromatid exchanges, cytotoxicity, carcinogenesis etc. Clinical, experimental and epidemiological studies suggest that free radicals …

The Ames Test in Twenty-first Century
Abstract: Since the 19th century, industrial development has increased exposure to mutagens and possible carcinogens. In order to avoid these health risks, several techniques have been developed to recognize genotoxins. In the 1970s, Dr. Bruce Ames and colleagues, studying the histidine operon of Salmonella typhimurium, observed that histidine (−) auxotroph mutants were reverted to histidine (+) upon exposure to a mutagen. The researchers further observed that known carcinogens were mutagenic to …

Designer Zinc Finger Nuclease: A Versatile Tool for Genome Editing in Animals
Abstract: In this review, is provided an update on the most popular approaches, including zinc finger nuclease (ZFN)-based gene editing by homologous recombination (HR), gene knockout, non-homologous end joining (NHEJ), and gene therapy in mouse. Zinc finger nucleases (ZFNs) are synthetic restriction enzymes evolved by fusing zinc finger that facilitate genome editing by creating a double-stranded break in DNA at a user-specified location. ZFNs are new tools that promise to radically …
