Gravity and Cancer
Gravity is a well-known, but little understood, physical force. Its intensity and direction have been constant throughout evolutionary history on Earth, making it difficult to understand what role, if any, this vector force may have on life as we know it. Based on evidence that cells cultured in simulated microgravity exhibit in vivo characteristics similar to the parent tissue and that gravity alters metabolic activity and expression of different genes and cell signaling in various cell lines, the present study addressed whether or not simulated microgravity provided a better culture environment to enhance cell adhesion and to study potential markers for diseased tissue. Simulated microgravity culture promotes aggregation of anchorage dependent cells, but understanding its effect on cell…

Generalized Hohenberg-Kohn theorise
In this article we have generalized the HK theorems to the added presence of a uniform magnetic field. We have considered the cases of the interaction of the magnetic field with the orbital angular momentum and proved a one-to-one relationship between the external potentials {v(r),A(r)} and the nondegenerate ground state densities {ρ(r),j(r)}….
HA Zeolite as a Recyclable Catalyst for the Green Synthesis of Aryl naphthoxazinone Derivatives
An efficient green procedure for the preparation of aryl naphthoxazinones, applying a three-component one-pot condensation reaction of 2-naphthol, aromatic aldehyde and urea in the presence of HA zeolite under heating conditions in dimethyl sulfoxide has been developed. The present procedure offers several advantages such as short reaction time, simple workup and moderate to high yields, recovery and reusability of the catalyst….
![Highly efficient epoxidation of alkenes with hydrogen peroxide catalyzed by [W(CO)6@DAB-MWCNT]](http://www.takbook.com/best/wp-content/uploads/2016/09/14747_1470763035-3.jpg)
Highly efficient epoxidation of alkenes with hydrogen peroxide catalyzed by [W(CO)6@DAB-MWCNT]
In the present work, highly efficient epoxidation of alkenes with H2O2 catalyzed by tungsten hexacarbonyl supported on multi-wall carbon nanotubes modified with 1,2-diaminobenzene is reported. The prepared catalyst, [W(CO)6@DAB-MWCNT], was characterized by elemental analysis, scanning electron microscopy, and FT-IR and diffuse reflectance UV-Vis spectroscopic methods. The prepared catalyst was applied as an efficient catalyst for green epoxidation of alkenes with hydrogen peroxide in CH4CN as solvent. This heterogeneous metal carbonyl catalyst showed high stability and reusability in the epoxidation reactions without loss of its catalytic activity….

Health-related variables and its health promoting Lifestyle predictors in cardiovascular disease patients
The principal cause for death in the world is cardiovascular disease which leads to the death of 71million people every year. Poor lifestyle is a contributing element in this regard. The present study aims at assessing the effects of health-related variables and lifestyle variables on the results of exercise in patience with cardiovascular disease. This is a cross sectional descriptive study. Patients were divided randomly into two groups based on the results of exercise stress test: positive exercise test (771 patients) and negative exercise test (771 patients). Patients’ lifestyles were assessed with a standardized questionnaire; Health promotion lifestyle profile- II.SPSS-22 software and chi-square tests and logistic regression were used for data analysis Based on the logistic…

HEALTH AND SAFETY RISK ASSESSMENT OF BEHSHAHR’S COMPOST STUFF BY WILLIAM FINE METHOD
Compost production process in the compost factory of Behshahr, Mazandaran Province, is accompanied with different hazards in terms of safety, health and environment due to nature and activities. As a result, there is the possibility of harm to humans, in the event of an accident. In this research William fine, FMEA method was used to evaluate health and safety risks of Behshahr’s compost plant. In these models, aspects recognition and ranking are based on objective observation sand the previous experiences o f accidents. Therefore,111 aspects were studied and 78 of them were identified and assessed with the risk priority number higher than degree of risk-taking and were divided to three levels of very high and high (%14), moderate (%84) and normal levels (224) and were analyzed and…

In silico determination and validation of oprL structure and b cell epitopes as vaccine candidate in Pseudomonas aeruginosa
Pseudomonas aeruginosa is an opportunistic, non-fermentative, gram-negative rod which is an important cause of nosocomial infection leading to septicemia and death. The mortality rate is higher than bacteremias caused by other gram-negative opportunistic pathogens. One of the most important features of the bacterium is its resistance to various antibacterial agents, and even newly developed antibiotics have failed to reduce the mortality rate associated with this organism. There is increasing interest in bacterial virulence factors as a basis for effective vaccines and immunotherapies. Extracellular products and cell structures of P. aeruginosa contain numerous antigens with different specificity. These antigens have different roles for the formation of host protective immunity against P….

In silico potential vaccine against oprF in multidrug-resistant Pseudomonas aeruginosa
Pseudomonas aeruginosa is an important cause of nosocomial infection and may lead to septicemia and death. P. aeruginosa septicaemia is associated with the highest mortality rate of all Gram-negative infections. Because of the general resistance of the organism to antibiotics, research has been focused on immunotherapy. There are several bacterial cell components incorporated into subunit vaccines. Vaccine studies have often focussed on lipopolysaccharide (LPS) and the outer membrane proteins (OPRs) due to its potent stimulation of the immune response. The major OPRs, OprF interested in the potential of OPRs as vaccines. Determination of OprF tertiary structure and theoretical methods for epitope prediction has been led to synthesis of such peptides that are important for immunodiagnostic…
