Pros of Designer Babies Genetic screening can reduce the baby's chances of being born with several serious diseases like Down Syndrome, Famial hypercholesterolemia, rare blood disorders such as Diamond Blackfan Anaemia, etc. Adam Nash was the world's first known designer baby born by the revolutionary pre-implantation process in the year 2000. Scientists genetically selected his embryo so that he would possess the right cells to save his dying sister's life. His sister suffered from Fanconi's anaemia (blood disorder), and mostly the chances of Adam getting that disorder was also very high. An embryo was chosen, which did not have Fanconi's anaemia.
He named the resulting substance Penicillin, and 5 years later it became the first usable antibiotic. Penicillin is produced by a group of fungi of the Penicillium genus. Streptomycin was the next widely used antibiotic, developed from a soil dwelling bacterium. This antibiotic is very useful for treating streptococcus infections and is even effective against tuberculosis. Several more antibiotic were developed in the years following and many emerged in the 1950s and 1960s.
However, the amount of Staphylococcus aureus that is antibiotic resistance gradually increased, until the year of 1950, the number rose to 40% of the patients, and 80% of the patients until the year 1960. The mechanism that made the bacteria become resistant to the antibiotic is that, a mutation to an extremely small amount of Staphylococcus aureus. From this mutation the bacteria began to produce an enzyme called penicillinase, which it breaks the molecule within penicillin that makes the antibiotic to function. Consequently, this antibiotic become ineffective and the bacteria eventually survived. This kind of Staphylococcus aureus is called “MRSA”, referred to methicillin-resistant S. aureus.
Discuss the genetic basis, incidence and effects of cystic fibrosis in human population Cystic fibrosis is a type of inherited genetic disorder that has affected human population for centuries. It was first clearly described by Dr Dorothy Andersen in 1938. Before this, cystic fibrosis was misdiagnosed as lung diseases such as chronic bronchitis. The discovery of this fatal disease leads to the research in medical laboratory to find out the causes, effects and cures for this disease. Throughout the centuries, many patients of this deadly disease died without being cured at very young age.
A Comparative Study of the Antimicrobial Properties of Species Allium on Four Different Microorganisms Using Well Diffusion, Disk Diffusion, and Microbial Count Plates Introduction For decades, myths have been circulating about onions and their supposed ability to keep people from getting sick due to antibiotic and antiseptic characteristics. The myth originated in 1919, when a serious outbreak of the flu had killed 40 million people. During this time, a doctor began visiting many different families to try and help fight the flu. The doctor met many families that had fallen ill to the flu before he finally met one that hadn’t. Curious as to how there was one healthy family against countless ill families, the doctor asked what the family had done to stay healthy.
This may be economic. In terms of short term mating preferences, Buss found that men would seek sex a lot earlier in a relationship, this is because over a period of one year, a man could spread his genes to countless numbers of women, yet a woman would only be able to have one child in the same time, so women become a lot more ‘picky’ in selecting their men. Buss and Schmitt found that short-term men tend to lower their standards and show a decrease in attraction to the woman after sex because they’d rather find someone else to spread their genes to. Buss found that in the long term, sexual selection should favour high levels of choosiness in both sexes. Women look for investment and protection, whereas males are attracted to women who show good signs of fertility.
Rosie Clarke Discuss sex differences in parental investment. Human females make a greater biological investment than males because they produce far fewer egg cells than males produces sperm, and egg cells are far more costly to produce. Another reason why females have a greater initial investment is that females can only have a limited number of offspring, whereas a male can potentially have a much larger number of children. As a result of this inequity, females are choosier in who they mate with. As well as making a larger prenatal investment, human mothers must also make a larger postnatal investment.
Sudden Infant Death Syndrome, or SIDS, is the third leading cause of death in babies (U.S. Department of Heath and Human Services). More babies die in a year of SIDS than cancer, leukemia, heart disease, cystic fibrosis, and child abuse combined (“Sudden Infant Death”). But what is SIDS? The definition is the death of an infant within its first year that cannot be explained after an autopsy, an investigation of the place where the baby died, and a review of the baby's and its family's medical history. But what truly causes it is a mystery that leaves scientists and doctors with just guesses and tests to do.
And out of that 20 million, 4000 of them die each year from asthma. Thesis: With asthma being quite common, I would like to get you all today to understand asthma a little bit more and that you can still be diagnosed with it today as I was only a few weeks ago. Preview: I will start off by telling you about the different types of asthma. Second I will explain the symptoms that go along with asthma. Third I will tell you about you can and is affect by asthma and finally what happens when you have an asthma attack and what you should do.
● A strong interest in or commitment to a project or cause that brings people together: community service, environmental concerns, neighborhood associations, animal rescue groups, etc. Suicide in other countries Suicide has become a major social and medical problem around the world. The World Health Organization (WHO) reported that one million people worldwide died from suicide in the year 2000. That is a global mortality rate of 16:100,000—or one death by suicide every 40 seconds. Since the mid-1950s, suicide rates around the world have risen by 60%.
