this study was conducted to investigate performance of native chickens produced in the centre of production and breeding of native chicken of isfahan in rural areas of isfahan province by using 1440 native pullets with age of 45 days in 4 towns and 2 climate zone of warm and cold. this study employed by coworking 60 rural families that 24 pullets with age of 45 days with ratio of 5 hen to 1 roo...
Today data communication is a modern technology that contains a powerful computer processor to exchange information. But brute force attacks are made to break the encryption techniques and these attacks are the main drawbacks of older algorithms. This paper is concerned with the development of a secure messaging system based on cryptographic algorithms that is which is more faster, better immun...
Voting is fundamentally a forecasting problem: voters try to predict future performance in office based on incomplete information about candidates. Forecast inputs combine observable professional qualifications with more subjective assessments of confidence and trustworthiness. In developing countries, the amount of information available can be quite limited. This paper explores how well voters...
BACKGROUND Pyrazinamide (PZA) is essential in tuberculosis treatment. We describe the prevalence, trends, and predictors of PZA resistance in Mycobacterium tuberculosis complex (MTBC) in the United States. METHODS We analyzed culture-positive MTBC cases with reported drug susceptibility tests for PZA in 38 jurisdictions routinely testing for PZA susceptibility from 1999 to 2009. National Tube...
As shown by the history of light, photons participate in most atomic and molecular interactions. Recent biophysical research has measured low light impulses, so-called biophotonic emission, in cells and biological tissue. It is reported throughout the world that all cells (plant, animal or human) emit a weak, so-called biophotonic radiation. Based on the photoelectric effect, appropriate photom...
The biology of the macro-element sulfur (S) is attracting an ever growing attention concerning cell physiology and human health. Sulfur metabolism works at the interplay between genetics and epigenetic as well as in the maintain of cell redox homeostasis. Indeed, unbalanced levels of S compounds in the body are actually under investigation as vulnerability factors and/or indicators of impaired ...
Little is known whether genetic variants identified in genome-wide association studies interact to increase bladder cancer risk. Recently, we identified two- and three-variant combinations associated with a particular increase of bladder cancer risk in a urinary bladder cancer case-control series (Leibniz Research Centre for Working Environment and Human Factors at TU Dortmund (IfADo), 1501 cas...
Dyslipidemia is a pathological condition in which lipid levels are deranged. It is a major health problem leading to dreadful complications such as Waja‘al-Qalb (angina pectoris), Khafaqan (palpitation) Iflas al Qalb (myocardial infarction), Siman-e-Mufrit (obesity), Ziabetus Shakri (diabetes), Sartan (cancer) and abrupt death etc. Overall prevalence of metabolic syndrome which includes dyslipi...
The role of HIV-1 minority variants on transmission, pathogenesis, and virologic failure to antiretroviral regimens has been explored; however, most studies of low-level HIV-1 drug-resistant variants have focused in single target regions. Here we used a novel HIV-1 genotypic assay based on deep sequencing, DEEPGEN (Gibson et al 2014 Antimicrob Agents Chemother 58∶2167) to simultaneously analyze...
BACKGROUND Invasive pneumococcal disease (IPD) results in high morbidity and mortality globally each year, although it is a vaccine-preventable disease. This study aimed to characterize the clinical features of IPD in a pediatric intensive care unit (PICU) in Taiwan. The seven-valent pneumococcal conjugate vaccine (PCV7) was introduced in the private sector in October 2005. The estimated covera...
