Cosmetics are products of chemical or natural origin dedicated specifically for use in skin and mucosa (1). The constant development of the cosmetic industry has generated the necessity to carry out microbiological analysis on the raw materials used in the industrial production of cosmetics as well as the final products, with the purpose of obtaining products of good microbiological quality (2).
Since Galton's time, scientists have realized that twin studies presented a unique opportunity for exploring the genetic basis of intelligence. Identical twins share exactly the same genetic makeup. Therefore, their inherited intelligence should theoretically be the same. When identical twins are reared apart, the resulting differences in their intelligence should be largely due to differences in their separate environments. Of course, this is not perfectly true. For one thing, twins do share at least one crucial part of their lives the prenatal part in the womb. For another thing, even when twins have been reared apart, they may have been placed in similar homes.
Like most tissues, the eye as a structure contains a great diversity of cell types. These range from the cells of the lens and the iris, to the melanin-containing retinal pigment epithelium, the cells of the choroid and retinal vasculature, and of course the numerous photoreceptors, neurons and supportive Muller cells of the retina. Such cellular heterogeneity will restrict the detection of changes in gene expression, as if a transcript is expressed in a rare cell type, even a massive change in expression may be undetectable as it reflects only a small fraction of the RNA population measured. Alternatively, changes in gene expression in one cell type may be masked by compensatory changes in other cell types, for example rhythms of gene expression in anti-phase. Even when changes in expression can be detected in heterogeneous tissues, determining the source of the change may be impossible. Overall changes could be due to a change in all cells within the tissue, a change in only a...
The gibberellins of tall pea plants containing the homozygous Le allele (wild type) were compared with dwarf plants having the same genetic makeup, except containing the le allele (mutant). Le and le are the two alleles of the gene that regulates tallness in peas, the genetic trait first investigated by Gregor Mendel in his pioneering study in 1866. We now know that tall peas contain much more bioac-tive GA1 than dwarf peas have (Ingram et al. 1983).
No strategies have yet been applied where multiple gene insertions are necessary to produce the metabolite or where plastid numbers have been increased. However, rapid accumulation of sequence data of both chromosomal DNA and expressed sequence tags of plants and other species is providing rapid advances in knowledge of the genetic makeup and functions of several plants, and it is expected that these other possibilities will soon be feasible.
In the development of new pharmacogenetic tests, as for any other clinically applied test, assay sensitivity, specificity, and positive predictive value will have to be scrutinized rigorously. In addition, the reliability of DNA testing in terms of intra- and interday variability and the rigor of assays when applied to multiple DNA samples will have to be demonstrated almost more carefully than it would be for routine assays for serum chemistries or hematology. This is because there are significant societal pressures that insist upon the accuracy of a diagnostic test that informs a physician and a patient about an individual's genetic makeup. The requirement for robust tests has not prevented any other technology from entering clinical practice though, and already a number of array-based genetic tests are available that are able to diagnose genotypes simultaneously at a relatively large number of loci.
In addition, treatments can involve the use of messy and or unpleasant smelling creams, such as coal tar-based ointments and camouflaging cosmetics, and regular attendance at clinics for time-consuming therapies, such as ultraviolet (UV) A B light therapy (Miles, 2002). The following quotes testify to these difficulties
A fourth application is associated with business management and sales. Management applies interpersonal relations to subordinates sales applies interpersonal relations to prospective customers. Adler's formula for effective interpersonal relations is simple Do not make the other person feel inferior. Treat workers with respect. Act as if they are intelligent, competent, wise, and motivated. Give subordinates the opportunity and the encouragement to do a good job, so that they can nurture their own social interest by having a feeling of accomplishment and contribution. Mary Kay Ash, the cosmetics magnate, said that she treated each of her employees and distributors as if each were wearing a sign saying make me feel important. A similar strategy should apply to customers.
The immediate, or direct, cause of all mass extinctions appears to be changes in the global atmosphere inventory. Changes to the atmospheric gases (which may be changes in volume or in the relative constituents of the atmosphere) can be caused by many things asteroid or comet impact, degassing of carbon dioxide or other gases into the oceans and atmosphere during flood basalt extrusion (when great volumes of lava flow out onto Earth's surface), degassing caused by liberation of organic-rich ocean sediments during changes in sea level, and changes in the patterns of ocean circulation. The killing agents arise through changes in the makeup and behavior of the at
Psychosomatic medicine embraced the notion that personality and physiology are intertwined. Psychosomatic theorists believed that certain diseases, such as diabetes, asthma, and hypertension, were associated with particular personality characteristics. They suggested that personality influenced the development of specific diseases. Although much of this theorizing has been disproved, these theorists did return the focus to investigating the interactive nature of a person's psychological and physiological makeup.
The racial makeup of the juvenile justice population varies by region of the country. In 2002, of all incarcerated U.S. juveniles, 77.9 self-identified as white, 16.4 as black, 1.4 as American Indian, and 4.4 as Asian. Hispanic ethnicity, aside from race, was 18 overall. Ninety-two percent of Hispanic juveniles identified racially as white. These percentages varied significantly
Drug-related epidemics have occurred, mercifully relatively infrequently. However, with each unfortunate episode, there is inevitably a variety of regulatory and clinical fallout. Indeed, the illnesses associated with ingestion of glycol-tainted linctus led to the Food, Drugs and Cosmetics ( ) Act in the USA, and the disastrous association of phocomelia with thalidomide propelled reforms of drug regulations worldwide. Other famous examples include, of course, practolol-induced ocu-lomucocutaneous syndrome, and, more recently, fenfluramine-induced myocardial fibrosis, and iso-tretinoin-associated birth defects.
Cosmetic preservatives allowed in the EU are prescribed in Annex VI of the Cosmetics Directive which includes details of concentration limits and restrictions for certain product types. In the UK, the Food Standards Agency publishes information on food additives and E-numbers.
Further support for the importance of position in determining cell fate has been obtained through observations of cell differentiation in leaves of English ivy (Hedera helix), which have a mixture of mutant and wild-type cells. When a mutation occurs in a stem cell in the shoot apical meristem, all the cells in the plant derived from that stem cell will carry the mutation. Such a plant is said to be a chimera, a mixture of cells with a different genetic makeup. The analysis of chimeras is useful for studies on the clonal origin of different tissues.
Traumatic memories are different, and are related to changes in the structure and function of the brain itself. Under normal circumstances, memories are formed when a person's senses register sights, sounds, and other sensory information, and pass on these data to an almond-shaped structure in the temporal lobe of the brain called the amygdala (which takes its name from the Greek word for almond ). The amygdala is the part of the brain that attaches an emotional meaning to the data provided by the senses. A nearby part of the brain called the hippocampus organizes the information relayed through the amygdala and combines it with previous information from similar events. For example, if a person is trying on several different types of perfumes at a cosmetics counter, the hippocampus will organize this memory according to previously established memory patterns of pleasant smells, perfumes, shopping trips, the specific
Mendelian inheritance is a term used to describe the hereditary patterns seen in diseases caused by DNA mutations in single genes inherited from parents by their offspring. Thus, Mendelian disorders include most of the rare primary immunodeficiency diseases described in this book. An increasing awareness of a genetic contribution to other diseases has led to the designation non-Mendelian or complex inheritance to refer to instances in which an individual's genetic makeup has a more variable and more complex role in disease causation. Examples of complex
Posttraumatic Stress Disorder symptoms have been associated with alterations in serotonin levels in the brain. Serotonin is an important neurotransmitter in multiple brain systems including the amygdala, the orbitofrontal cortex, the LC, the hippocampus, and the nucleus accumbens. Although the amygdala sits at the center of the fear circuit and receives and projects to many brain regions, it is thought to typically ignore most information coming to it. It has a reaction point or set point, and it is not simply reactive. Its reaction point is controlled or determined by many processes (see the discussion of the medial pre-frontal cortex), but it also has an internal control mechanism mediated by its internal neurochemical makeup. Danger signaling stimuli overcome the amygdala's typical set point. The neurochemical set point of the amygdala can be significantly altered in two ways by inputs having been altered upstream in the circuits sending input projections to it and if its own...
The next year, Congress passed the Immigration Act of 1924, which limited the number of immigrants who could enter the country. Strict quotas were set for each national group. Since the quotas were based on the makeup of the U.S. population in 1890, before the recent wave of immigration from southern and eastern Europe, the quotas for those areas were quite low. Public sentiment against immigration was strong enough that the bill probably would have passed in any case. Nevertheless, the support of respected psychologists such as Yerkes and Brigham certainly bolstered the cause.
California, Oregon, and Wisconsin have laws that require recycled content in some plastic containers. The Wisconsin law requires at least 10 recycled or remanufactured content in plastic containers except those for food, beverages, drugs, and cosmetics. There has evidently been little enforcement of this law, and it has had little effect.
There are two major avenues of gene therapy based on cell types. Cells involved in genetic transfer from an individual to offspring are termed germ cells, whereas somatic cells makeup various organs of the whole body. Alterations in somatic cells are confined to an individual's genetic constitution and are nonhentable In the case of germline gene therapy, foreign genes are injected to fertilized eggs and the resulting changes are transferred both to somatic as well as germ cells and are passed along to future generations.
Early theories of crowd behavior hypothesized that unruly crowds were made up of criminals or the mentally deficient. Proponents of this perspective assumed that crowd behavior could be explained by the makeup of the individual personalities of people in the crowd and that certain kinds of people were more likely to be found in a crowd. Le Bon provided a more psychological analysis of crowd behavior, recognizing that even people of high intelligence could become members of an unruly crowd. He believed that crowds transform people, obliterating their normal abilities to be rational and putting them in a hypnotic, highly suggestible state. Le Bon disapproved of crowd behavior in all forms. Consequently, in his book he painted an extremely negative picture of crowd behavior.
Animal behavior occurs as a result of the actions of the nervous and endocrine systems. There is a complex interplay among these two body systems, the environment, and an individual's genetic makeup in terms of the cause-and-effect, stimulus-response events that constitute behavior. An animal receives external information via its special senses (eyes, ears, nose, mouth) and somatic sense organs (touch, pain, temperature, pressure). This external information travels along sensory neurons toward the brain and spinal cord, where the information is analyzed and a motor response to the external stimulus is initiated. Some of these motor responses will be directed toward the sense organs, locomotory muscles, and organs such as the heart and intestines. Other impulses will be directed toward the hypothalamus, which controls body cycles such as all endocrine system hormones, heart rate, sleep-wake cycles, and hunger.
Secrecy and self-disclosure are two opposite forms of communication that can alter couple functioning by shaping what issues couples' feel able to discuss with one another and how needs for closeness and separateness are managed (Feeney & Noller, 1996). Secrecy in skin disease involves safety behaviours such as making excuses to avoid activities involving exposure of the skin and concealing affected areas through the use of clothes or cosmetics. In existing relationships, even if a skin condition is openly acknowledged, secrecy may operate if conversations about the disease are subtly avoided. Partners may be equally anxious over what to say or how to set a fitting tone of conversation without saying the wrong thing and potentially embarrassing themselves or their partner. Sometimes, the location of a condition is not immediately apparent, thus the decision as to whether or when to tell Avoidant Attachment Style 'I never leave the house without makeup, even if it's to go to the shop...
According to Skinner, each person is unique, but not because of choices the individual makes. Rather, personality arises from genetic makeup and the different experiences each person is exposed to during their lives. In addition, individuals remain under the influence of their environment throughout the lifespan, regardless of the degree of learning that has preceded.
A 55 solution of this compound (Fig. 2.29) is available commercially as Glydant (Lonza U.K. Ltd., Cheltenham, U.K.). This product is water-soluble, stable and non-corrosive, with a slight odour of formaldehyde. It is active over a wide range of pH and is compatible with most ingredients used in cosmetics. It has a wide spectrum of activity against bacteria and fungi, being active at concentrations of
Therapeutic response and side effects (Walker et al., 2004). The field of pharmacogenomics looks at the determinants of drug response at the level of the entire human genome using DNA analysis. The goal is to eventually individualize therapy based on a person's genetic makeup (Basile, Masellis, Potkin, & Kennedy, 2002).
Genetic differences have often been invoked to account for racial disparities in a number of birth outcomes, including preterm birth. Although a woman's genetic makeup undoubtedly plays a role in the pathogenesis of preterm birth, the potential genetic contribution to racial disparities in preterm birth is unknown. First, it is not known which genes contribute to racial disparities in preterm birth rates. For example, interleukin-6 (IL-6), gamma interferon (IFN-y), and tumor necrosis factor alpha (TNF-a) have all been implicated in the pathogenesis of preterm birth. Although several population-based studies have shown that African Americans are more likely than whites to carry genotypes that induce a high level of expression of IL-6 (Cox et al., 2001 Hassan et al., 2003 Hoffmann et al., 2002), the findings for IFN-y and TNF-a are less consistent in some studies the prevalence of individuals with genotypes that induce high levels of expression of these two proinflammatory cytokines was...
This chapter addresses a range of problems that arise with quantifying gene expression with quantitative PCR (qPCR), drawing upon the author's experience using the eye as a model system. The eye (or more specifically the light-sensitive retina), as well as mediating the primary events of vision, provides an accessible model of the nervous system. However, the lightsensitive nature of this tissue makes analysis of ocular tissues difficult as dynamic changes in gene expression may occur during tissue collection. The diverse cellular makeup of the retina also presents a problem in the form of assessing gene expression in a heterogeneous tissue. When dealing with models of retinal degeneration, these problems are compounded by very small tissue samples and, furthermore, when the pathways of interest involve numerous transcripts, high-throughput assays become essential.
The FDA was established as a law enforcement agency in 1930. At that time, the Federal Food and Drugs Act of 1906, which prohibited false and misleading statements about a drug or its ingredients, and the Shirley Amendment (1911), which subsequently prohibited false therapeutic claims in drug labeling, were the only two substantive regulations governing the research and development of pharmaceuticals. In 1938 Congress passed the Federal Food, Drug and Cosmetic (FD&C) Act, both in response to recommendations from the FDA to revise the obsolete 1906 Federal Food and Drugs Act, and as a result of an elixir of sulfanilamide, which caused 107 deaths, mostly in children, because of its adulteration with glycol. The FD&C Act required that drug safety be established before marketing and extended regulations to cosmetics and therapeutic devices. It did not address the issue of drug efficacy, however. Factory inspections and standards for food quality and containers were also authorized. The...
The changes in behavior produced by learning are accompanied by changes in physiological makeup. Learning is associated with changes in the strength of connections between neurons (nerve cells in the brain), some quite long-lasting. Eric R. Kandel and his colleagues have documented the changes in physiology underlying relatively simple learning in giant sea snails, progressing to more complex behaviors in mammals. Similar physiological changes accompany learning in a variety of organisms, highlighting the continuity of learning across different species.
The ever increasing consumer demand for naturalness of foodstuffs and cosmetics along with the enormous potential of plants in biosynthesis and bioconversion represents an attractive basis for plant aroma biotechnology. The potential market for biotechnology-derived flavors and fragrances is estimated to be 10 or more of the overall flavor market, which was expected to amount to 10 billion in 2000, tendency ascending (1). Indeed, up to now, the lion's share thereof accounts for microbially catalyzed processes (74). Contrary to the successful generation of high-value pharmaceuticals, plant cell cultures still need to be shown to be competitive with field plants or microorganisms in the production of flavor compounds on an industrial scale. To reach this aim, the productivity of the cell culture systems will need to be improved significantly. Most promising starting points are given by recombinant DNA technologies (75). The genetic information responsible for fruit and herbal flavor...
Most hospitals and healthcare organizations participate in a purchasing group to leverage volume-driven price advantages. The makeup and operations of these groups vary widely, but the price agreements and changing landscape of drug pricing add an additional dimension to the drug price factor. A specific drug may be the lowest price option for a given contract period, after which the choice may change. In another variation, a package of prices for bundled items may cause the price for a given item to change, depending on the use of yet another item. How this influences formulary decisions is a function of the drug and many other factors.
Much of the information concerning the compounds properties and uses is found in the manufacturers' information brochures. Any person wishing to explore their use should consult the manufacturers. An ever-present problem with cosmetics preservation is that of contact sensitization. This is discussed in some detail by Marzulli and Maibach (1973) and is a point which must be carefully checked before a preservative is committed to a product. Another hazard which may arise is that of an induced change in the skin microflora during continuous use of products containing antimicrobial preservatives this is discussed by Marples (1971).
Because of the many variables which affect the activity of antimicrobial agents, it is almost impossible from a mere scrutiny of the literature to select a preservative that will be optimal in a particular product. Legislation passed in the USA by the FDA requires the manufacturers of cosmetics to declare the ingredients in their products and to state their function or purpose.
Epigenetic effects of nutrients and other dietary factors (e.g. antioxidants) during embryonic development, not gene mutations, have recently provided a plausible link between genetic makeup and susceptibility to development of chronic diseases 35 . DNA methylation is a major modifier of the genome,
