Effects of a bioactive molecule, Menthol on a stock pest - Bog af Mahdi Trad - Paperback

The present study aimed to evaluate the insecticidal activity of a bioactive molecule, Menthol towards a pest species, Rhyzopertha dominica. The effects were examined on mortality, enzymatic biomarkers, nutritional reserves, digestive enzymes and oxidative stress biomarker. Toxicological tests performed by fumigation and ingestion revealed the insecticidal activity of this molecule with a dose-response relationship. Moreover, Menthol applied by ingestion is more effective compared to fumigation...

Superficial bladder tumors - Bog af Sarra Ben Rejeb - Paperback

Non-muscle-invasive bladder tumours (NMIBTs) are tumours with an unpredictable course. Endoscopic and histological prognostic factors have been identified, but remain insufficient, leading us to propose new molecular prognostic factors. 40 TVNIM were collected over a 6-year period (2008-2013), and immunohistochemical studies were carried out on E-cadherin, an intercellular adhesion molecule, and ¿-cathenin, a molecule associated with E-cadherin. An inverse correlation between E-cadherin on the one..

An anti-hyperglycemic molecule, RNF01 - Bog af Joharinera Rakotobe - Paperback

This book was written to study the antihyperglycaemic activity of the RFN01 extract in mice. In vivo tests were performed in mice made hyperglycaemic after glucose overload (2 g/kg, per os) and by alloxane injection (150 mg/kg, i.p.). RNF01 reduced the transient hyperglycaemia induced by glucose overload to 6.85 ± 0.24 mmol/l and 5.95 ± 0.62 mmol/l at 400 mg/kg and 500 mg/kg compared to the control which was 8.85 ± 0.62 mmol/l (p

Eugenol: Microbiological properties and its effect on biofilm - Bog af Khalil Bouassida - Paperback

Eugenol is a simple molecule, but it has many beneficial properties for humans, animals and plants. The mechanism of action, in some cases, is still poorly understood. The property most coveted by researchers is eugenol's antibiofilm activity, making it an excellent alternative to antibiotics. Eugenol has many uses in different sectors of biotechnology, is low in toxicity and is readily available in commercial quantities.

Research into bionanocomposites with therapeutic properties - Bog af Mehdia Gandi - Paperback

Highlights of this scientific book:Biosourced nanocomposite materials have been attracting increasing attention in recent years, making them of interest in biomedical research.Chitosan (CS) is one of the most widely used molecules in these structures, acting as a matrix. Our research has focused on this molecule, and on silver nanoparticles (in particular), as synergistic reinforcers of antibacterial activity. Despite this, we've also talked about other biopolymers and metallic antiseptic agents,..

Functional Nano-Biostructures - Bog af Guillermo Bracamonte - Paperback

In this publication, results obtained and discussed on the fabrication of synthetic Nano-Biostructures have been presented. They have been designed based on Escherichia Coli bacteria and silica-coated metallic core-shell nanoparticles. For this purpose, nanoparticles of reduced dimensions within the nanoscale were synthesized by means of the Turkevich soft reduction method. They were modified with variable lengths of silica spacers (Au@SiO2). On the obtained nanoparticles a fluorescent molecule of..

Obstacles to collaboration between traditional medicine - Bog af Abdoulaye Poly - Paperback

In developing countries, particularly in Africa, the widespread use of traditional medicine is often due to its accessibility. Many traditional medicine providers seek continued (or increased) recognition and support for their practices. At the same time, many modern medical professionals, especially those in developed countries with a strong history of medical science, have begun to express strong reservations. Indeed, whereas modern medicine is analytical and attacks the problem with a single molecule,..

Calculation of the activities of the father-son pair of a 99Mo/99mTc generator - Bog af Dorra Ben Sellem - Paperback

Nuclear medicine is a medical speciality based on the administration of radiopharmaceuticals to patients. Radiopharmaceuticals are composed of a cold molecule, specific to an organ or function, and a radionuclide. The isotope most commonly used in imaging is 99mTc, thanks to its physical properties (pure gamma emission, physical half-life of six hours and energy of 140 keV), its chemical properties (coupling with numerous cold molecules) and its availability. It is produced by a 99Mo/99mTc generator,..

In this book you can find information on the history of the discovery of nucleic acids, with an emphasis on RNA. There is also an introduction to the structure and functions of this molecule. The emphasis of the book is on different techniques used to extract RNA from the hippocampus of Wistar rats, from commercial methods to a technique carried out in house. Analyses were carried out to ensure that the RNA was extracted and to compare the quality of the methods.

History of organic chemistry - Bog af Ouksel Louiza - Paperback

The importance of organic chemistry lies in the fact that carbon is the molecule of life, creating the structures of all living things. The applications of organic chemistry are represented in most of the products you use. Your computer, your furniture, your home, your car, your food, your perfume, your medicines and your body all contain organic compounds. In this book, we present the history of organic chemistry to help you understand where it comes from, and how it came to be the way it is today!..

The social value of face in communicative interaction - Bog af Luyara Rodrigues de Almeida Mariano - Paperback

This publication is intended for undergraduate and graduate students, as it deals with the relationship between language and culture in the effective use of language and had for theme the examination of how the sociological concept of \face\ occurs in Chinese culture, specifically in Mandarin, and how these people express themselves in order to achieve politeness and maintain their social face. For this, the comparison parameter used was the way used by the Brazilian culture, especially the Portuguese..
