Fedoroff Agric & Food Secur (2015) 4:11 DOI 10.1186/s40066-015-0031-7 Open Access REVIEW Food in a future of 10 billion Nina V Fedoroff* Abstract Over the past two centuries, the human population has grown sevenfold and the experts anticipate the addition of 2–3 billion more during the twenty-first century. In the present overview, I take a historical glance at how humans supported such extraordinary population growth first through the invention of agriculture and more recently

What is autism? Definition Autism is a severely incapacitating developmental disorder of brain function characterized by three major types of symptoms: impaired social interaction, problems with verbal and nonverbal communication, and unusual or severely limited activities and interests. The definition of Autism and Autism Spectrum Disorder (ASD) is provided by the Diagnostic and Statistical manual of Mental Disorders (DSM-IV). Children with autism are less able to interact with the world as

cancer is a malignancy that affects the ovaries, that is, the female gonads. A provoke are genetic mutations that alter the normal DNA content in the ovary. Ovarian cancer. The origin of these genetic changes It is at present still unclear; about, doctors have formulated some theories, but have blind spots. Causes: It's not clear what causes ovarian cancer. In general, cancer begins when a genetic mutation turns normal cells into abnormal cancer cells. Cancer cells quickly multiply, forming a mass (tumor)

Neurodegenerative Disorders: Alzheimer’s Disease 1. Amyloid Precursor Protein (APP) Alzheimer’s disease (AD) remains a major cause of senile dementia, which is characterised by an impairment of neuronal and synaptic function in addition to the accumulation of β-amyloid plaque and formation of neurofibrillary tangles within distinct portions of the brain (De Strooper and Annaert, 2000). Progression of this distinct pathology of neurodegeneration does not typically vary from patient to patient

SSM2 Introduction Eukaryotic cells contain hair-like projecting organelles, known as cilia and flagella, which are involved in many sensory and motile functions of the human body, thus any abnormalities in their characteristic 9+2 axonemal structure or their functioning can lead to many different disease processes. In my review I will look at the structure and functions of eukaryotic cilia in the human body and the ways in which mutated or abnormal gene expression can result

Describe the structure-function relationships of human IgG and how might such an understanding influence the choice of IgG subclass in potential antibody-based therapies? Our body is under constant attack whether from external with viruses, bacteria and parasites or from the internal; with the development of tumour cells in cancer. We have a number of ways to prevent organisms from entering our body and surviving. This includes our skin, mucous membranes and the low pH of our stomach acids. However

There are many different types of skin disorders that can affect anyone. There are rare, common and life threatening disorders or conditions. There is a skin disorder called Lamellar Ichthyosis, (LI), it is a rare genetic skin condition that affects about 1 in 100,000 individuals in the United States. It’s when the skin develops normally, but it doesn’t shred like it’s supposed to, casuing thick, tight, scaly skin. There are two different types of LI: Limited lamellar ichthyosis and Erythrodermic

1. Summarize the stages of the cell cycle, including the steps of Interphase. G1 phase - growth and synthesis. Gap phase 1 begins at the completion of mitosis and cytokinesis and lasts until the beginning of S phase. This phase is generally the longest of the four cell cycle phases and is quite variable in length. During this phase, the cell chooses either to replicate its deoxyribonucleic acid (DNA) or to exit the cell cycle and enter a quiescent state (the G0 phase). S phase Replication

In this phase, the initial population will be created using the data and mutation for each and every test data. The population created will be compared with the set of chromosomes made in the training phase. If the population created is loosely related with the training data then it will be removed. The remaining samples of the population will become the population of a new generation, crossover and mutation operations will be performed. The process will continue till the size of generation reduces

our lives. Our generation has been labeled as lazy, technology obsessed, and many other stereotypes referring to our dependence on technology. Technology also has the ability to change the appearance and genetics of the next generation. An arising method of genetic engineering has the ability to genetically modify the DNA of a fetus to resemble specific traits. Initially, it may sound like a genius discovery. However, this procedure could change everything we know about our world. It goes against
