Assessment of body composition in Sri Lankan children: validation of a skin fold thickness equation. | Morbidity associated with obesity is related to the fat mass (FM) of the body. The direct estimation of FM is difficult. Skin fold thickness (SFT) is a simple and cheap alternative for accurate assessment of FM, and population specific equations are necessary for accurate assessment of FM using SFT. To develop a SFT pr... | 18,982,800 |

Big pharma and health care: unsolvable conflict of interests between private enterprise and public health. | A landmark paper on Game Theory showed that individual maximization of profit necessarily endangers the public good, and since the problem has no technical solution, "it requires a fundamental extension in morality" (1). We propose here that public health, as a public good, now emerges as a grave example of this proble... | 18,982,834 |
Use of the lecompte procedure for ventriculoarterial connection abnormalities in infants and children with congenital heart diseases. | The Lecompte (REV) procedure is used to correct abnormal ventriculoarterial connections in patients with congenital heart diseases; it avoids the need for an extracardiac conduit for pulmonary outflow tract reconstruction. The present study aimed to investigate effectiveness and criteria of the REV procedure in childre... | 18,982,867 |
Diagnosis and endovascular treatment of spontaneous direct carotid-cavernous fistula. | Spontaneous direct carotid-cavernous fistula (CCF) is relatively rare and few reports have been found in the literature. The aim of this paper was to report the clinical characteristics, imaging findings and curative effect of endovascular treatment for patients with spontaneous direct CCF. We retrospectively analyzed ... | 18,982,868 |
Personality, cognitive coping strategies, and adaptational outcomes in a sample from the general Spanish population. | The relationship among scores on two personality dimensions, Emotional Stability and Extraversion, and on two cognitive coping strategies, Positive Thinking and Wishful Thinking, and on the Consequences of Coping scale were examined in 169 Spanish persons (78 men and 91 women; Mage = 36.3 yr., SD = 12.1). Positive Thin... | 18,982,936 |
Predictors of responses to organizational wrongdoing: a study of intentions of management accountants. | It has been proposed that employees aware of organizational wrongdoing face two decisions: whether or not to blow the whistle and whether or not to leave their organizations. Of these only the decision to blow the whistle has received attention, leaving a gap in knowledge; thus, a survey of 330 management accountants w... | 18,982,945 |
Psychometric properties of Scheier and Carver's Life Orientation Test in a sample of Australian prisoners. | The psychometric properties of Scheier and Carver's 1985 Life Orientation Test (LOT), which is a measure of optimism, were examined as part of a study of education, training, work experience, and expectations of sentenced adult prisoners in Western Australia. All prisoners at five metropolitan public prisons were invit... | 18,982,960 |
[Remote results for cases of non-small cell lung cancer treated by limited resection]. | The choice between the limited pulmonary resection and the standard anatomical resection depends on many factors. The most important are the tumor size, age and general condition of the patient. We present 12 patients with non-small cell lung cancer-IA stage, who underwent limited resection. The 5-year survival rate is... | 18,983,002 |
[Could the transrectal prostate biopsy predict the rate of positive lymph nodes in prostate cancer patients?]. | Since 1989, when Hodge and al. demonstrated transrectal ultrasound guided prostate biopsy, it has become a "gold standard" for the diagnosis of prostate cancer. According to the experience gained in the period 1999-2003 in the Department of Urology-Medical University, Sofia, in a prospective follow-up of 20 prostate ca... | 18,983,007 |
Evaluation of bean (Phaseolus vulgaris) seeds inoculation with Rhizobium phaseoli and plant growth promoting rhizobacteria on yield and yield components. | To study the effect of co-inoculation with plant growth-promoting rhizobacteria (PGPR) and Rhizobium, on yield and yield components of common bean (Phaseolus vulgaris L.) cultivars was investigated in 2 consecutive years under field condition of plant growing evidence indicates that soil beneficial bacteria can positiv... | 18,983,036 |
Antimicrobial susceptibility pattern of microorganisms involved in the pathogenesis of surgical site infection (SSI); A 1 year of surveillance. | The aim of this study is to identify the antibiotic sensitivity pattern of pathogens involved in the process of surgical site infection, in surgical wards. Changes made in the pattern of antibiotic use will result in different microorganism susceptibility patterns, which needs correct determination for precise empiric ... | 18,983,037 |
Future perioperative registered nurses: an insight into a perioperative programme for undergraduate nursing students. | An Australian College of Operating Room Nurses (ACORN) submission (ACORN 2002-2008) recently stated that the specialities that suffered significantly from the transition of hospital-based nursing training to university training were the perioperative specialty, critical care and emergency.

Dissociating people from nature. | Conservation measures that dissociate people from their native landscape can destroy traditional ecological knowledge and hurt the very biodiversity that the conservation policies aim to protect. | 18,983,073 |
Effects of organic carbon supply rates on uranium mobility in a previously bioreduced contaminated sediment. | Bioreduction-based strategies for remediating uranium (U)-contaminated sediments face the challenge of maintaining the reduced status of U for long times. Because groundwater influxes continuously bring in oxidizing terminal electron acceptors (O2, NO3(-)), it is necessary to continue supplying organic carbon (OC) to m... | 18,983,077 |
Polybrominated diphenyl ethers in peregrine falcon (Falco peregrinus) eggs from the northeastern U.S. | A total of 114 peregrine falcon eggs from nests in Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island, and Vermont were analyzed for polybrominanted diphenyl ethers (PBDEs). Eggs were collected from 1996 to 2006, excluding 1997 and 1998. Total PBDE concentrations ranged from 74.5 to 6610 ng/g wet weight, wi... | 18,983,080 |
