Assisted conception has historically developed in an environment of relatively low success rates and increasing commercial and clinical pressure to attain greater pregnancy rates. Partly because of these pressures, the history of ART is replete with numbers of innovations that have promised increased success and that have become "fashionable" for a period of time before tending to become less widely adopted and/or regarded as a major advance. One possible explanation for this chain of...
The work reported here mainly emphasis on magnetostriction and magnetisation properties of NiFe/FeCo multilayer thin films. Ni81Fe19 exhibit low coercivity and near zero magnetostriction while Fe50Co50 exhibit high coercivity and high magnetostriction. In simple words this project aims to study the change in properties of FeCo by changing the thickness of NiFe underlayer. A thin film with low coercivity and high magnetostriction constant has potential applications in the field of strain...
The neuralians, animals with nervous systems (Nielsen, 2008), first began to populate the earth during the Cambrian era. The function of these nervous systems was to sense and relay information about surroundings. Neuronal networks comprise both sensory cells and communicating cells, which interact via chemical or electrical synapses (Westfall, 1996). Many signalling molecules and transcription factors that are critically implicated in neural development are highly conserved among animals,...
Ecosystem is a distinct space on earth where community of living organism including flora and fauna interact with the abiotic elements like air, water and soil as a system. The interaction between the biotic and abiotic components of the ecosystem is linked together through energy flows and nutrient cycles.Biologists define biodiversity as the totality of species, genes and ecosystems of a region. This encompasses genetic diversity, species diversity and the ecosystem diversity. Traditionally,...
Abstract The optic pathway at present represents the best model to understand the molecular mechanisms contributing to axon guidance. In recent years a great number of interactions have been shown to play a role in this process.This review will give a broad overview of the steps involved in the development of the optic pathway, focusing in particular on the Slit-Robo signalling system. Introduction The visual perception of the surrounding environment is transmitted from the eye to the central...
Avian Influenza also known as  avian flu and  avian flu  is defined as An influenza caused by viruses adapted to avians. Among all the types of Avian Influenza the Highly Pathogenic Avian Influenza (HPAI) is of the prime concern among them.The disease called Avian Influenza have similarities on the basis of sign and symptoms and adaptation of hosts with the "Horse Flu", "Dog Flu", "Swine Flu" and also with the "Human Flu".Approximately all documented...
The study investigates occurrence of ionic contaminants and pollutants in the tributaries and main river of Chirchik Watershed in Tashkent region in Uzbekistan. Water samples collected in the Chirchik Watershed were analyzed by an ion liquid chromatography to analyze ions such as Ca2+, Mg2+, K+, NH4+, Na+, Li+, SO42-, NO3-, Br-, NO2-, Cl-, F-, PO43-. Plant available forms of heavy metals in soils were extracted according to the methods established by Japanese Ministry of Environment. Elements...
Scope of protein folding. Proteins are the biomolecules which plays and pivotal role in this living world. They are responsible for expression of certain characters in different types of cells and around 50% of the total cell dried mass. Proteins are the chain of amino acids which bind with polypeptide backbone and then fold in a unique 3D (native structure) by which expression of the protein take place, Various forces and factors are responsible for the protein folding and due to the minute...
Grafting with selected resistant rootstocks for the purpose of controlling diseases, pests and abiotic stresses is an ancient practice conducted on a variety of wood plants. French grape industry that was almost destroyed by phylloxera (Dactylosphaera vitifolii) in nineteenth century was one of the famous examples. The crisis reversed only until grafting susceptible French grapes on a phylloxera resistant rootstock (Mudge et al 2009). Researches on herbaceous vegetable grafting started in...
The occurrence of inorganic arsenic in food has received worldwide concern during recent years due to its toxicity and adverse health effects. It is known to be a human carcinogen and can cause skin and bladder cancer. Inorganic arsenic (Arsenite and Arsenate) are not only commonly found in the ground water, they are also found to be the predominant species in some food such as rice. Reliably monitoring of inorganic and organic arsenic level in our environment is the one of the most important...
