Lead Toxicity in Children Lead poisoning in children was first discovered in 1890 in Queensland, Australia. The lead source was not identified until 1904, when a researcher traced it to the paint used on railings and verandahs. The first discovery of lead poisoning in the United States (with a traceable source) was in 1914; the child had chewed the paint off of his crib. At this time they linked lead poisoning as a cause of convulsions in children. As research progressed and more children were
MLX-NLC gel stored at different temperature and humidity conditions (Table 1) were evaluated for any changes in particle size, PI, zeta potential, and drug content at 30, 60, 90 days time points to assess the effect of storage conditions on the stability as a function of time. The particle size was monitored at regular time intervals during storage to assess particle aggregation. The nanoparticles are thermodynamically unstable system and for their stability, a zeta potential value between –30 mV
Lead Toxicity: Its Effects on Fetal and Infant Development Lead toxicity has been an area of unending research in recent years. There have been positive and negative correlation’s relating its toxic effects to both child developmental deficiencies and adult regression problems. This review will focus on the problems associated with the children. It will discuss various routes of entry of lead into the child’s system, both prenatally and postnatally, the mechanisms employed by lead to cause the
Everyday scientists perform different tests on cells (known as in vitro testing) to assess numerous concepts, such as drug efficiency and nanoparticle toxicity. Unfortunately, these tests do not always provide the best or most accurate results since the human body is composed of several different cell types, all of which interact and cause robust responses that cannot accurately be mimicked or studied with single cells. Thus, current techniques are being employed to imitate the complexity of the
Forensic toxicology is a branch of forensic science concerned with the study of toxic substances or poisons; toxicology is the study of the toxic or harmful effects of chemicals. It is concerned with how toxins act, when their harmful effects occur, and what the symptoms and treatments are for poisoning. It also involves the identification of the substances involved (Interdisciplinary). Forensic toxicologists have faced numerous challenges throughout the 1800’s and are still facing some of these
• Mr. Toxic Free (Tony Freeman) is a University professor of toxicology and an expert at toxic substances and chemicals. • He works at night to find toxic wastes and fights with her worst enemy Father Toxane to clean the toxins and our environment. • Father Taxane can change his appearance into many different toxic substances such as toxic pesticides, dioxins, PBC's and radioactive toxic wastes, etc.... • Toxic substances are very harmful to the environment and can lead to many different problems
environment and our lives. It is caused by the disposal of electrical appliances due to malfunction, exhaustion or obsolescence. This type of pollution is a concern due to its rapid growth and popularity in today’s society as well as the high levels of toxicity contained within such appliances (Hein Online citation: 17 Vill. Envtl. L.J. 307 2006). Body An article on The Human and Environmental Effects of E-waste by Lucy McAllister states that roughly 40 million metric tons of electronic waste is produced
danger that tags along with this benefiting science does need to be understood before their usage becomes prevalent. Environmental scientists who are concerned about health of organisms and hazard to environment are researching and accessing about toxicity, distribution and fate of the nanoparticles that is released into the environment. Properties of nanoparticles can impact the environment in a negative way. The surface effects of nanoparticles are both favourable and unfavourable. When they are
Every being on earth are dependent on environment because of its mother nature of providing most of the essential things needed for daily life, such as , food, air for respiration, lumber to make houses, etc. Especially for us, human beings, environment plays an important role in maintaining our health by providing the requisites to make healthy body. Even though everybody has a clear understanding of the importance of environment, people are degrading it. Because of the increasing population and
According many scientific researchers, our entire population has been dowsed with chemicals. There are several aspects of this dowsing that should concern us. First, and foremost, many of these chemicals are suspected to have damaging health effects on humans, as well as, other life forms. Second, most of these chemicals have only recently been produced so the environment is clearly changing and being challenged by these newcomers. Third, almost all of these chemicals exist in the forms and

Digoxin Toxicity Digoxin toxicity, also called digoxin poisoning, is the condition of having too much digoxin in the blood. Digoxin is a medicine that is used to help a weakened heart function properly. Digoxin increases the strength of the heart muscle, helps to maintain a normal heart rhythm, and helps to remove excess water from the body. When there is too much digoxin in the body, it acts like a poison (toxin). Digoxin toxicity can be life-threatening, and must be treated in a hospital. CAUSES
The “miracles of science” has brought on an era of super materials that are unaffected by extreme conditions and provide us many overlooked benefits that are a part of our everyday life. Clothing that resists open fire and moisture, gasses used to fuel your automobiles air conditioner, to plastics that release that fried egg from the fry pan with perfection. These discoveries made by DuPont can arguably yield some of the most significant products made by man in the 21st century. One among the
Toxicity Testing on Animals Each year million of animals die in laboratories due to animal toxicity testing. They are often tested on for household products, drugs, and cosmetics. Animal testing is cruel and wrong. They should not be tested on just for human safety. Animal rights are being violated because they do not have a choice to do anything. They should be entitled with the rights that humans have. Animals suffer in pain and it does not benefit humans. Proponents may think animal testing
The coloration of an organism is often correlated to its ability to hide or advertise. However, we can correlate it to the organism’s level of toxicity. We see the relationship between colors and toxicity in many different organisms. The relationship is shown in different classes of vertebrates like the reptiles, amphibian and mammals. The reptiles show a very wide variety of animals that show either crypsis or aposematism. The Bothriechis schlegelii (Eyelash pit viper) is an example of a snake that
What is Nitrox? Enriched Air Nitrox, Oxygen Enriched Air, Nitrox, EANx, Safe Air Breathing in the Deep The common gasses used in diving include compressed air and Nitrox. Nitrox is a mixture of gas composed of nitrogen and oxygen. Nitrox also contains normal air, which is 78% nitrogen, 21% oxygen and 1% of other gasses, primarily argon. Scuba diving is diving with a self-contained underwater breathing apparatus, that is completely independent of surface supply. Providing the diver with the advantages
Pre-clinical testing is performed to Good laboratory practice (GLP) and covers pivotal toxicology & safety pharmacology studies. In preclinical research, scientists test their ideas for new biomedical prevention strategies in laboratory experiments or in animals. “Pharmacokinetics (PK) and pharmacodynamics (PD) can be seen as two sides of the same coin. PK and PD have a definite relationship, assessing how much drug gets to the site of action and then what that action is. Both activities are essential
Animal Experimentation. It has been said that “not testing new pharmaceutical products on animals is highly dangerous” (HIV and AIDS Information and Resources). Many tests that are done on Animals and then released for the general use are; “Acute toxicity tests consisting of the administration of a single dose of a chemical at a concentration great enough to produce toxic effects and death. An example of such a test is the Lethal Dose 50 (LD50) test in which 50 per cent of the subjects in an experimental
Should animal testing be banned? Now，animal testing is still a controversial subject, and the scientists are facing an increasing problem, which more and more people appeal to stop animal testing. The original purpose of animal testing was inventing drugs for human diseases. For example, Scutti (2013) states that 98 of Nobel Prizes awarded for Physiology or Medicine, 75 were directly dependent on research from animals. The four non-animal experiment prize winners were also relied on the data, which
