Chapter 1 The Problem Introduction Today’s technological innovation and medical advances gave birth to formulation of synthetic drugs used to treat respiratory infections‚ urinary tract infections‚ diarrhea‚ arthritis and other diseases. These pharmaceuticals are costly and to a point‚ inaccessible to many Filipinos. These may also pose adverse effects like nausea‚ dyspnea‚ and diarrhea. Researchers are challenged to produce natural medicines‚ which could be lower in cost and more synergistic

For example‚ I have long struggled with the ability to consume legumes. I bought into the standard advice that it’s a problem of gut flora‚ if you eat them long enough your gut will adjust and digest them better without gas‚ etc. If I had a large Coke and a large burrito‚ the result was 100% predictable: great intestinal discomfort. However‚ I now know that was simply another problem of failing to suppress

1) A) Why were artificial sweeteners introduced and when was the first product made with them sold? B) Are there any studies to find out if the gut floras are affected by aspartame since it was first researched as an inhibitor for a gastrointestinal secretory hormone medication? C) Were there any studies done on the artificial sweeteners that are now in almost all pre-made foods before they were introduced on the market‚ if so what were they? D) Who first introduced artificial sweeteners for human

NUTRITION IN CRITICALLY ILL PATIENTS‚ EARLY INTRODUCTION AND MAINTAINANCE- NURSES ROLE Nutrition is very vital in critically ill patients‚ often the neglected area of critical care where researchers and analysts had been concentrating on for a long time. Guidelines and protocols have been formulated by institutions and organisation‚ but compliance had been identified as the reason to experience abasement in proper nutrition. Stroud (2007)

Topic: Cystic Fibrosis Introduction Cystic Fibrosis (CF) according to Cohen 2004‚ is the most common fatal hereditary disease amongst children and adults. It is an autosomal recessive disorder‚ and most carriers of the gene are asymptomatic. The flawed gene that causes CF affects the glandular secretions by altering chloride transport across cell membranes. Thickening of bronchial secretions leads to infection and other respiratory disorders. Other mucus secreting glands

Our guests also generate microscopic vitamins and anti-inflammatory substances that our body cannot produce on its own. In the digestive tract‚ the components of the intestinal microbiota (formerly called "Flora") help us absorb nutrients and make certain compounds digestible food. ‘Without the gut bacteria die by not absorb the necessary amounts of vitamins‚’ says biologist Antonio Lazcano‚ professor of the Faculty of Sciences of the UNAM. Lazcano adds that without the beneficial microorganisms in

Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane bound organelles and they have relatively small ribosomes. They also do not contain and endoplasmic reticulum.1

Study shows disadvantages of GM foods to human health British scientific researchers demonstrated that genetically modified DNA from crops can find its way into human gut bacteria‚ raising possible health concerns. This is because antibiotic-resistant marker genes are inserted with GM material‚ which could cause a person to be resistant to antibiotic medicines. The study was conducted at Newcastle University on seven human volunteers who‚ in the past‚ had their lower intestine removed and now use
