Background: Beta 2- micro globulin (β2-MG) is involved in human malignancies. Increased synthesis and release of β2-MG, as indicated by elevated serum, plasma, or urine β2-MG concentration, occurs in several malignant diseases.
Objective: The study was designed to assess the role of serum Beta2- micro globulin in the support of the diagnosis of different types of pediatric malignancies.
Subjects and Methods: This case - control study was carried out on 137 children and adolescents with newly diagnosed pre-treated malignant diseases who were admitted to pediatric oncology center at Basra Children’s Specialty Hospital, their ages ranged from 3 months to 15 years, during the period from the 1st of November 2014 till the end of October 2015, 71 were males and 66 were females and 148 healthy children and adolescents (83 were males and 65 were females) matched for age and sex regarded as control group. Cases and control characteristics were assessed from data collection by special questionnaire. All patients and control group were investigated for Beta2- microglobulin by the enzyme-linked immunosorbent assay.
Results: The study had revealed that level of Beta2-microglobulin was significantly higher in patients with malignancy in comparison to control group, P value < 0.001.Also the serum Beta2- microglobulin level for both hematological malignancies and solid malignancies was assessed and it was found that significantly higher percentage of elevated serum Beta2- microglobulin level was present in patients with hematological malignancies in comparison to solid malignancies, P value <0.01.The study also had revealed that there was a significant correlation between the initial white blood cells count ≥ 50000 cells/ml and abnormal serum Beta2- microglobulin level, P value < 0.01,but there was no significant differences in serum Beta2- microglobulin level in relation to risk groups and immunophynotypes of acute lymphoblastic leukemia ,morphological subtypes of acute myloid leukemia, stages of each type of lymphoma (Hodgkin lymphoma and non-Hodgkin lymphoma) and the histopathological subtypes of non-Hodgkin lymphomas. After subjecting variables (specific to acute lymphoblastic leukemia) to logistic regression analysis, the significant independent risk factor that associated with abnormal serum Beta2- microglobulin level was high initial white blood cells count (≥50000 cells/ml).
Conclusion: Serum Beta2- microglobulin level is significantly higher in patients with hematological malignancies and high initial white blood cells count(≥50000cells/ml) .From this study, serum Beta2- microglobulin could be recommended in the initial work up for diagnosis of childhood malignancy.
In the present work, samples of building material are analyzed for their naturally occurring radioisotope activity such as uranium, radium, and radon. The radon emission rates, and the annual effective doses, "AED”, are also investigated. The activity of twenty-four samples, taken from the local markets of Saudi Arabia, was determined using the "Sealed-cup Technique” and Solid State Nuclear Track Detectors, "SSNTD.” The uranium concentration activity of the samples is found to vary from 0.62 to 4.68 ppm with an average of 1.92±0.42 ppm. The radium concentration varies from 0.61 to 4.64 Bq·kg−1, with an average of 1.91±0.42 Bq·kg−1, the radon concentration in the samples varies from 42.29 to 319.97 Bq·m−3 with an average of 131.53±28.94 Bq·m−3. The value of the dissolved radon concentration in the collected samples varies from 12.99 to 98.97 Bq·m−3 with an average of 40.41±8.89 Bq·m−3. The mass exhalation rates are found to vary from 1.54 to 11.65 mBq·kg−1·h−1, with an average of 4.79±1.05 mBq·kg−1·h−1, while the surface inhalation rates vary from 76.97 to 582.35 mBq·m−2·h−1, with an average of 239.38±52.66 mBq·m−2·h−1. The AED due to indoor uses varies from 1.07 to 8.07 mSv·y−1, with an average of 3.32±0.73 mSv·y−1. The AED due to indoor plus outdoor uses varies from 1.47 to 11.10 mSv·y−1, with an average of 4.56±1.0 mSv·y−1. The results of this study show that the values obtained for most samples are within the internationally accepted recommended values. Therefore, these samples can be used as building materials as they do not pose a major risk to humans.
Background: The fundamental cause of obesity and overweight is an energy imbalance between calories consumed and calories expended.
Aim: To clarify and figure out food habits and different lifestyle pattern among a sample of Palestinian women attending the nutrition center in the Gaza Strip.
Methods: A cross-sectional study involved 116 women were randomly chosen by purposive census sampling. They aged 25 to 60 years with a diagnosis of obesity. The data collected by interview questionnaire that included social factors, lifestyle habits, and health/disease history.
Results: Age group variable has distributed significantly (p=0.024), (31.0%) of morbid obese were ≥35 years group compared to (13.5%) of morbid obese amongst the younger group. The higher intakes of legumes (OR: 2.134, P=0.003), nuts (OR: 3.917, P=0.019), eggs (OR: 6.840, P=0.009), fast foods (OR: 4.461, P=0.005), and soda drinks (OR: 2.230, P=0.004) were the risk factors linked to the increased risk of morbid obesity. Moreover, the higher intakes of legumes (OR: 8.439, P=0.011), eggs (OR: 6.900, P=0.041), chips (OR: 5.049, P=0.012), sugar (OR: 2.068, P=0.011), and fast foods (OR: 3.029, P=0.025) are risk factors of chronic diseases.
Conclusion: The study identified several lifestyle factors and improper dietary habits associated with obesity among women in Gaza city. There is a great need to change these habits to avoid the increased risk of obesity. Gene-environment interaction can explain the high incidence of obesity. A national plan of action to overcome obesity is urgently needed to reduce its economic and health burden
Treatment of various inflammatory processes, including acute pneumonia(АP), over the past decades is identical and does not reflect the specifics of a particular disease. The basis of such treatment is «antibiotics alone». The need for additional therapeutic efforts is realized by the use of General therapeutic techniques, regardless of the diagnosis. This does not take into account the important fact that the localization of inflammation not only determines its clinical picture,but,above all,the mechanisms of influence on other organs and systems of the body.
Physicists are generally trained in the Standard Model of Physics (SMP). This implies that they perceive and account for only 3 dimensions of space in a moment in time (3S-1t) (a 4-dimensional [4D] model). However, applying the SMP, more than fifty significant conundrums have arisen that are unexplained or incomplete. Explaining these within the SMP 4D fabric led to hypothesizing a ‘fifth force’, most recently the hypothetical ‘X17 particle’. We propose this hypothetical X17 may better be explained by a 9-dimensional model (9D) with gimmel. Our model, the Neppe-Close Triadic Dimensional Vortical Paradigm (TDVP) has amplified the ‘physics’ from 4 dimensions to 9D, specifically first postulating and then further demonstrating mathematically—starting with derivations of the Cabibbo angle—that 9 dimensions must exist. Moreover, this data is empirically demonstrated because the neutron, proton and electron mass-energy-gimmel equivalence in the Triadic Rotational Units of Equivalence (TRUE) as part of the TDVP model, exactly corresponds with the normalized data for the mass-energy equivalence volumetric data for these particles in the CERN Large Hadron Collider. This data shows definitively that we exist in a 9-dimensional finite, quantized, volumetric, spinning reality. This is, furthermore, embedded in an infinite continuity (9D+). Mathematically, applying this 9D+ model definitively requires an extra third component that is massless and energyless (‘gimmel’). Without gimmel, no particle in the universe would be stable. TDVP unifies nature because the same laws apply across the quantum, macro-world and cosmological reality. Our 4D experience is simply the physical component of 9D+ existence.
Summary Amplification: At all levels, there is the consistent application of a 9-Dimensional quantized finite reality embedded within an infinite continuity. The application of gimmel specifically requires applying the 9-dimensional model and is based on necessary mathematical calculations not only at the quantal level (where the fifty plus unsolved, unexplained or contradictory conundrums can be explained somewhat, and there is no longer ‘quantum weirdness’), but at the macroscale level with more gimmel in the life elements (which, additionally, are consistently all cubic multiples of 108 cubed), as well as cosmologically, where the correlations with proportionate Dark Matter and Dark Energy are overwhelming. Moreover, these 9-dimensional plus factors together with Triadic Rotational Units of Equivalence (TRUE) and gimmel, allow numerous solutions that couldn’t otherwise be solved. For example, importantly, applying the simple mathematics of TRUE, we can demonstrate why gluons, while adequate in 4D, are impossible applying 9D. These solutions are simpler because we have markedly adapted George Spencer-Brown’s ‘Laws of Form’ to applying a new method of mathematical calculation, Edward Close’s ‘Calculus of Distinctions’ (COD) which recognizes quantal limits and that the nature of finite reality is quantized and volumetric. The COD includes distinguishing between content, extent, and impact. We emphasize the pioneering works of Wolfgang Pauli with his multidimensional model and his ‘Pauli Exclusion Principle’, Alfred Whitehead with ‘Process Philosophy’ and his ‘Principia Mathematica’ (with Bertrand Russell), Georg Cantor with Set Theory, and Roger Penrose with spinors and twistors. TDVP is a prime example of our broad new specialty of ‘Dimensional Biopsychophysics’ (DBP). DBP extends physics, consciousness, and the biopsychosocial to extra dimensions and applies mathematics empirically. Like Max Tegmark, we recognize the key role of mathematics as fundamental in nature, not just for application in calculation and operations.
Circular Economy, Sustainability, Design for Environment are some of the keywords that identify new formidable challenges to be faced in the next years. Raw materials have a dominant role in reaching that goal. Green energy, electric vehicles, communication, etc. depends on raw materials labeled as critical because of their economic importance coupled with high supply risk. For this reason, mitigating actions need to be used in materials selection and design such as material substitution, improved materials efficiency and recycling. In this technical communication, a method to implement raw materials criticality issues in materials selection is described according to the recent literature. The strategy is based on Ashby’s approach and the definition of the alloy criticality index quantifying the criticality per unit of mass of the material.
Endothelial dysfunction and inflammation play a key role in the pathophysiology of diabetic nephropathy; Tetrahydrobiopterin (BH4) is an essential cofactor for nitric oxide synthase, when BH4 is reduced to dihydrobiopterin (BH2), endothelial dysfunction is induced.
Purpose: The aim of this study is to evaluate the relationship between the levels of biopterins with albuminuria in type-2 diabetic hypertensive patients.
Methods: We studied 30 hypertensive type-2 diabetic patients in whom biopterins levels were measured by reverse phase high performance liquid chromatography with fluorescence detection. Additionally, 24 h urinary albumin excretion was also measured (nephelometry). The levels of biopterins and albuminuria were correlated with the Pearson correlation coefficient.
Results: We did not find a significantly correlation between biopterins levels and albuminuria, However, we found a significantly inverse correlation (R= -0.498, p<0.005) between the BH4/BH2 ratio and albuminuria.
Conclusion: Our results suggest that the BH4/BH2 ratio instead of biopterins levels may be a marker of nephropathy in hypertensive type-2 diabetic patients.
The non-force magnetic fields were first predicted by Chandrasekhar in 1956 in his well-known published work [1]. Since then there have appeared a large number of theoretical studies [5,6,15,17] with the research into various aspects of physical manifestations of non-force magnetic fields. However by now their existence in the technical physics and in laboratory experiments has not been experimentally confirmed [30]. Nevertheless the indistinct presence on the Earth of such fields was, in a sense, discovered in the natural electromagnetic field much earlier.
Objectives: Natural disasters confront individuals, communities and governments with the challenge of rebuilding and addressing psychosocial sequelae. With the increasing number of natural disasters it is timely to evaluate the efficacy of interventions and strategies to address the mental health needs of individuals and the community.
Method: An evaluation of literature related to the psychological impact of natural disasters, treatment efficacy and government strategies to confront the social and psychological impact of natural disasters for the period 1983-2016 was undertaken.
Results: Epidemiological studies following natural disasters despite the use of differing psychological measures demonstrate significant psychological morbidity - anxiety (7-42%), complicated grief (28-41%), depression (6.5-38%), post-traumatic stress disorder (11-89%) and substance misuse (1.3-24%). Intervention studies post-disaster demonstrate efficacy variability.
Conclusions: The increase in the number and impact of meteorological and hydrological events since the 1980s and the psychological, social and economic consequences of these events has resulted in the development and implementation of government policies to confront the immediate and long-term adverse outcomes. The focus is typically on resources and infrastructure redevelopment with less focus on social and mental health interventions with long-term evaluation of interventions uncommon. The consequence of natural disasters emphasizes the importance developing strategies to ensure effective evaluated psychosocial interventions are available across at-risk communities.
A quantum mechanical model that considers tunneling and inelastic scattering has been applied to explain the hole transfer reaction from a G (Guanine) base to a GGG base cluster through a barrier of Adenine bases, (A)n (n = 1-16). For n = 1, the ratio of tunneling to inelastic scattering is about 6, which is sharply decreased to around 0.23 and 5.23 × 10-8 for n = 4 and 16 respectively, suggesting dominance of inelastic scattering for n ≥ 4. As in experiment, the calculated product yield ratios (PGGG) exhibit a strong distance dependence for n < 4, and a weak distance dependence for n ≥ 4. We also predict conditions under which oscillatory or non-oscillatory charge transfer (CT) yield are expected.
