This method resulted in the production of small crystals, where the graphene oxide wraps around the ammonium perchlorate particle to form a composite particle. The resulting composite material is found to enhance the thermal decomposition of ammonium perchlorate over just physically mixing. Crossref Google Scholar. All rights reserved.

About this article Cite this article Semenov, A.The carious status of the first permanent molar FPM was studied in school children aged 9—12 years from a randomly selected primary schools from Sharfia area of Jeddah, Kingdom of Saudi Arabia. The sample consisted of children from each age group of 9, 10, 11, and 12 years old.

In total, Almost one-third The children who had received advice regarding oral hygiene from a dentist or parent had more sound FPMs compared to the children who did not receive any advice. The number of carious FPMs increased with age.

The prevalence of caries of the FPM was high and increased with increasing age. The level of knowledge had a positive correlation with the caries levels amongst this cohort of scholars. Jeddah is a commercial city situated at the western coast of Saudi Arabia.

In the Sharfia district of Jeddah, majority of people are from India, Pakistan, and other Asian countries. In this region, there have been no studies undertaken to determine the prevalence of dental caries in first permanent molars FPMs. In recent years, the global distribution of dental caries presents a varied picture; most of the countries with low caries prevalence are experiencing an unprecedented increase in caries prevalence and severity of dental caries including Saudi Arabia.

On the other hand, in several industrialized countries, a reduction of dental caries incidence and improvement of gingival health care are evident [ 12 ]. This decline in dental caries is mainly due to appropriate use of fluorides and preventive oral health measures [ 34 ].

Dental caries is one of the most highly prevalent diseases in children, and the FPMs are important as they are very prone to caries because of their anatomical structure and early eruption in the mouth.

As a result, many children have to visit the dental professional requiring restorations or extractions of these molars. This is expensive, time consuming, and often traumatic for the young child.

Hence the prevention of dental caries remains an important responsibility of the dental profession. Many studies [ 34 ] have stressed the importance of oral hygiene instruction, the regular use of topical and systemic fluoride, and the application of fissure sealants in the prevention of dental caries especially on the first permanent molars.

Several studies have reported high dental caries prevalence in school children from Saudi Arabia and other developing countries [ 5 — 11 ].

The frequency of involvement of dental surfaces by caries lesions varies with age, and peak of intensity occurs during certain stages of human life [ 12 ]. The incidence of caries among the various teeth varies considerably. The morphology, time of eruption, and positioning of the tooth in the oral cavity confer inherited disadvantages or advantages to the various methods used in the control of plaque and hence tooth decay and losses.

One Function - Engines of Creation (Dual Vision Remix)

A Japanese study showed that most of occlusal caries occurred years after their eruption [ 16 ]. These studies showed that, with increasing age, there was an increase in the prevalence of dental caries of the first permanent molars. In Jeddah, similar to other Saudi cities, the prevalence of dental caries is high and it is essential to obtain base line data regarding the condition of the first permanent molars so that appropriate prevention and treatment options can be implemented.

This study was unique as it set out to determine the baseline data of a community that was neglected. This data will serve as a basis for the introduction and monitoring of intervention and educational oral health programmes for this community. Follow-up studies will be done on an annual basis to monitor the outcomes and if necessary modify and improve the oral health package that will be recommended.

Depending on the results obtained, relevant and practical recommendations will be suggested. The aim of the study was to determine the prevalence of dental caries in the first permanent molars among 9—year-old school children from the Sharfia district, Jeddah.

The second aim was to correlate the prevalence of caries in relation with the dental knowledge. A cross-sectional analytical study design was used to determine the prevalence of dental caries in the FPMs. A total of school children were examined from randomly selected primary school in the Sharfia district, Jeddah. The sample consisted of a total of male and female children from each age group of 9, 10, 11, and 12 years Figure 1.

The sample size for the study was determined using pathfinder survey technique as described by the World Health Organization WHO [ 21 ]. Consent for examination of the children was obtained from the respective headmaster of the schools. The primary school children were examined by two trained and calibrated examiners. Kappa statistic 0.Fam Pract Manag. Eighty health care organizations, including the AAFP and the AMA, recently joined together to ask Congress to include a fix for the Medicare physician reimbursement formula in any Medicare bills considered this year.

Without such action, Medicare payment rates for physicians could fall 4. Earlier this year, Congress averted a 4.

Due to the SGR, if the cost of services to beneficiaries grows faster than the gross domestic product, Medicare payments to physicians and other practitioners are cut.

At press time, both chambers of Congress were debating Medicare reform bills, including prescription-drug coverage proposals. Only the House had added an amendment to address the Medicare reimbursement formula.

What does it take to hire a nurse these days? On average, it takes 16 percent more money than it took one year ago, according to Allied Consulting, a national recruitment firm. Irving, Texas: Allied Consulting; Rising malpractice insurance premiums remain a source of concern for physicians across the country, and lawmakers are working on a variety of measures to address the crisis. In March, the House passed bill H. The Senate has not yet agreed on a bill. Twenty state legislatures are considering medical malpractice legislation, and at least 11 states have already passed such bills this year, reports the May 28 New York Times.

To provide short-term relief, Sen. Dick Durbin D-Ill. Under the proposal, physicians in high-risk specialties such as obstetrics, surgery, trauma care and neurology would be eligible for a tax credit of 20 percent of their total malpractice premiums.

Other physicians would be eligible for a percent tax credit. Proponents of the bill say it would provide needed relief as physicians wait for true reforms to take effect. Critics say the bill would force taxpayers to bear the burden of high malpractice premiums.

Meanwhile, the Common Good, a bipartisan legal reform coalition, is calling for more radical solutions to the malpractice insurance problem. The group also wants to enact reforms that would increase the incentive to settle malpractice cases and set limits on how much lawyers could collect e.

The group is filing legal petitions for the reforms in 12 states. To combat the problem of health illiteracy and improve communication with your patients, encourage them to ask three simple but essential questions at every visit:. Available online at: www. Among the recommended practices are the following: Prepare patient care summaries or other records from the original source documents, not from memory; use only standardized abbreviations and dose designations; require that verbal orders be repeated to the prescriber to verify the accuracy of what was heard; and ask patients to recount what they have been told during the informed consent discussion.

Researchers found that approximately 40 percent of respondents with Internet access searched the Web for health care information or advice inbut only 6 percent used e-mail to contact a physician or other health care professional. Although few respondents reported e-mail communication with a physician, about 25 percent did use e-mail to discuss health issues with family or friends.

In a recent Harris Interactive Poll ranking how well 15 industries serve their customers, hospitals came in third, behind supermarkets and packaged food companies. Pharmaceutical companies and health insurance companies were close to the bottom of the list, ranking eleventh and thirteenth, respectively. Over 60 percent favor limiting awards that punish doctors for their negligence.

Although a poll showed the majority of the public viewed malpractice lawsuits as somewhat effective for reducing preventable medical errors, 57 percent now indicate patients are suing doctors too often. A new guide developed by the Agency for Healthcare Research and Quality helps patients do their part in reducing prescription errors. Inthe same survey, which then included some primary care physicians, found that only 5 percent of physicians would choose a different field.

Authors of the survey attribute the attitude change to increasing concerns about malpractice, dealing with managed care and other payers, and availability of free time.

In the field of pharmaceutical research and development, biotransformation studies have been extensively applied to investigate the metabolism of compounds leads, lead candidates, etc.

The microbial biotransformation phenomenon is then commonly employed in comparing metabolic pathways of drugs and scaling up the metabolites of interest discovered in these animal models for further pharmacological and toxicological evaluation. Microorganisms can conveniently afford drugs difficult obtained via synthesis.

The plethora of reported microbial biotransformations along with its added benefits has already invoked further research in bioconversion of novel and structurally complex drugs. This review alternatively discusses the prospect of microbial biotransformation studies as a significant element ameliorating drug discovery and design in terms of cost-effectiveness, environment protection and greater structural diversity as compared to animal models used to study metabolism.
