TLP Sequenced and Studied for Its Functions with Targets Diagnostic and Therapeutic: Recent Perspective | Chapter 16 | Innovations in Medicine and Medical Research Vol.2

From the first analysis of immuneprecipitation followed by Western Blotting (WB) Corin and TLP seem to precipitate at the same height (approximately 50 KDa) and are recognized by the same antibodies. In parallel the tests of immunoprecipitation by the use of cell extracts derived from lung cancer cells A549 and NCI-H23 are improved with the aim to be able of obtaining a precipitate containing only the TLP. In fact the partial aminoacid sequence of TLP showes a high homology with the sequence of human Corin (only one aminoacid is different) and is present in lung cancer under different isoforms. It is known that human Corin is expressed mostly outside the cells and the protein extract derived from the extracellular medium and from the cells transfected with the plasmid, which overexpresses Corin, showes many more bands analyzed on SDS-PAGE that are equivalent to the bands (about 50-100 KDa) observed in the WB analyzed with anti-TLP.

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t

Nutritional Analysis of Octopus hubbsorum B (Cephalopoda: Octopodidae) from the Pacific Ocean, Acapulco, Guerrero, México | Chapter 02 | Recent Advances in Biological Research Vol. 5

Introduction: Mexico is a country with nutrition-related problems, mainly regarding protein-energy deficit and low consumption of minerals and vitamins. This has contributed to Mexico ranking second on adult obesity within countries of the OECD (30% of the population). On the Mexican littoral, many cephalopods exist but only few octopods are used for human consumption. According to Mexican authorities, only four species of octopods are fished, although there are 15 of these benthonic zone organisms that can be used for many purposes. Aim: To establish the micro and macronutrient values of O. hubbsorum B and to evaluate its potential contribution to Mexican diet, since this organism is available all year in the Mexican Pacific Coast. Study Design: Transversal study. Place and Duration of Study: Samples of Octopus hubbsorum were bought from fishermen in Acapulco, in the Mexican Pacific Coast during Autumn 2016. Methodology: Five O. hubbsorum were bought from local fishermen du

Optimization of Biodegradation of Phenol in a Refinery Effluent Treatment Facility | Chapter 11 | Recent Advances in Biological Research Vol. 5

Background: Regulatory agencies in Nigeria and all over the world demand that refinery wastewater (RWW) meet stipulated regulatory limits before discharge into the environment. Biodegradation of toxic hydrocarbon constituents of these effluents, such as phenol, has remained a challenge with regards to compliance with regulatory requirements. Aims: This study investigated the effect of micronutrients and macronutrients on the biodegradation of phenol in RWW. Methods: The micronutrients used in the study were CoSO 4 , MnSO 4 , ZnSO 4 and CuSO 4 while the macronutrients comprised urea and NPK. Range-finding and optimum concentration tests were performed for each of the nutrients. The experiment was carried out in a 3L Erlenmeyer’s flask incubated in a rotary shaker under experimentally determined optimum cultural conditions, using a fractional factorial design. Phenol concentration (mg/ml) was monitored daily throughout the experiment using spectrophotometric method.
