The effect of Fig on antioxidant and oxidative parameter of normal young men in a clinical trial study

Background and aim: Today, due to the increased production of free radicals such as pollution, there is a need to a good antioxidant resource. Fig which is one of the fruit mentioned in the Qur'an, may prevent increased production of free radicals because of its rich content of antioxidants. This study was aimed to study the effect of using figs on oxidant and antioxidant parameters on healthy young men. Materials and methods: In this clinical trial, 74 healthy male students were chosen randomly and divided into two groups of test and control. Age range was 18- 40, and residency in university’s dormitories were entry criteria and disease, smoking and taking other complements were exclude criteria. The test group receive daily 120 g dried fig for four weeks. Blood samples were obtained from two groups at beginning of study and after 4 weeks. Total Antioxidant Capacity (TAC) was measured by FRAP method, activity of GGT and the rate of Fe were matured by auto analyzer system BT 3000. Results: results indicate that Fe level has a significant decrease as an oxidative parameter in the test group (N= 37) after four weeks of interference (p=005/0). GGT and TAC levels showed a significant increase as antioxidant parameters in the test group after four weeks of interference (p= 0/001). Conclusion: Considering the significant decrease in Fe level as the oxidative parameter and substantial increase in GGT and TAC level as the antioxidant parameters, Figs can play an effective and useful role in increasing the antioxidant defend of the body against free radicals and so decrease damages caused by oxidative stress

A study of the time of hospital discharge of differentiated thyroid cancer patients after receiving iodine-131 for thyroid remnant ablation treatment

The aim of this study was to measure the radiation exposure rate from differentiated thyroid carcinoma (DTC) patients who had received iodine-131 (131I) treatment, and to evaluate hospital discharge planning in relation to three different sets of regulations. We studied 100 patients, 78 females and 22 males, aged 13 to 79 years (mean 44.40±15.83 years) with DTC, in three Groups who were treated with 3.7, 5.5 or 7.4GBq of 131I, respectively. The external whole-body dose rates following oral administration of 131I were measured after each one of the first three hospitalization days. A multivariant linear analysis was performed, considering exposure rates as dependent variables to the administered dose for treatment, age, gender, regional and/or distant metastases, thyroglobulin (Tg), antibodies to Tg and thyroid remnant in the three dose groups. We found that the exposure rates after each of the three first days of hospitalization were 30, 50 and 70μSvh-1 at 1m. All our DTC patients had an acceptable dose rate on days 2 and 3 that allowed their hospital discharge. After only 1 day of hospitalization, just 3/11 cases showed not permissible exposure rates above 70μSvh-1. In conclusion, it is the opinion of the authors that after measuring the exposure rates, most treated, DTC patients could be discharged after only one day of hospitalization, even some of those treated with high doses of 131I (7.4GBq). Patients, who received the higher doses of 131I, should not be released before their individual exposure rate is measured

The Competency Requirements for Quantity Surveyors: Enhancing Continuous Professional Development

Quantity surveyors are construction economists who fulfill varied and comprehensive duties to support cost-effective construction and property development projects. The core competencies of quantity surveyors include determining project budgets, measuring project quantities, preparing contract documentation (such as Bills of Quantities and Cost Control Documents), administering contracts, and preparing final accounts. Despite being recognised as a professional discipline distinct from architecture and civil engineering since 1836, quantity surveyors are not immune to the threats and changes in their operating environment. Some parties in the construction industry have been critical about the quality of works and services provided by quantity surveyors. Some even question the importance of appointing quantity surveyors as project consultants. Because of these challenges, the profession needs to regroup and take stock of the whole situation so that they will not become extinct in the future. All parties who have vested interest in the development of the profession, be it the students, educators, registered as well as unregistered quantity surveyors must find an answer to arguably, the declining roles of quantity surveyors and the lack of recognition they receive in construction projects. Two pertinent issues that had been discussed by these people are: the competency level of practicing quantity surveyors who offer their services to the clients; and the amalgamation of a set of competency standards into professional quantity surveyors’ training, formally named as ‘continuous professional development’ (CPD) by the profession. Competence, in any sphere of work, can be a difficult concept to pin down. It is particularly difficult when it relates to professional occupations where roles can be complex and the knowledge and skills involved many and varied. Recognising the importance of professional competence, a research looking into issues relating to quantity surveyors’ competency had been conducted by the Universiti Sains Malaysia, Malaysia. The on-going research looks into the national competency standards, industry needs, job profile charts, and delivery of learning materials to quantity surveying students. The research findings reveal that, quantity surveying educators and practices alike, are still deeply entrenched in the ‘traditional’ core competencies rather than the newer and more novel services and skills. The research respondents however, recognised that university educators in the field of quantity surveying need to develop a comprehensive course syllabuses that cover the whole spectrum of knowledge/cognitive, functional, and behavioural competencies in order to produce competent and employable quantity surveyors for the nation. Lastly, the respondents are generally supportive of having a Malaysian version of competency standards for the quantity surveyors. They are also confident that these standards can become the lynchpin for a comprehensive continuous professional development programme.   Keywords: Competency, Continuous Professional Development, Occupational Skills, Quantity Surveying, Trainin

Optimal time repair of ventricular septal rupture post myocardial infarction

Ventricular septal rupture (VSR) is an uncommon complication of myocardial infarction (MI). The mortality rate of VSR is high. The management of VSR is including the stabilization of the hemodynamic status and surgical closure of the rupture. In spite of the agreement of experts on the necessity of surgical repair, the timing of VSR repair management remains unclear. In this review article, we evaluate the optimal time repair of VSR. To collect the data, Pubmed, EMBASE, and Cochrane Central Registry databases were searched for potentially suitable studies. Search terms were including “Ventricular Septal Rupture”, “Myocardial Infarction”, “Timing”, and “MI”. According to the result of the studies, it seems that the time between VSR detection and its repair is a determining factor in the survival or mortality of patients in post-myocardial infraction VSR. Studies showed that earlier surgical repair in VSR increases the risk of mortality, because in the early phase after MI, infarcted myocardium is very fragile, and it is very difficult surgical repair and increases the risk of recurrent septal defects. The longer time is needed for the heart and different body systems to adapt to the hemodynamic results of the abrupt left to right shunt. It seems that the best time for the operation is after the maturation of VSR with scarring at the edges of the defect. Moreover, in a large number of patients, it is not possible to delay the operation since they are at risk of severe heart failure and organ dysfunction. In these cases operation immediately after diagnosis of VSR is recommended to prevent further hemodynamic deterioration. In hemodynami-cally compromised patients, it may be considered to use a ventricular assist device, requiring an intra-aortic balloon pump (IABP), or extracorporeal membrane oxygenation (ECMO) preoperative to postpone the operation which leads to higher survival in post-MI-VSD

Resolving Spin-Orbit and Hyperfine Mediated Electric Dipole Spin Resonance in a Quantum Dot

We investigate the electric manipulation of a single electron spin in a single gate-defined quantum dot. We observe that so-far neglected differences between the hyperfine and spin-orbit mediated electric dipole spin resonance conditions have important consequences at high magnetic fields. In experiments using adiabatic rapid passage to invert the electron spin, we observe an unusually wide and asymmetric response as a function of magnetic field. Simulations support the interpretation of the lineshape in terms of four different resonance conditions. These findings may lead to isotope-selective control of dynamic nuclear polarization in quantum dots

Evidence of the Coulomb force effects in the cross sections of the deuteron-proton breakup at 130 MeV

High precision cross-section data of the deuteron-proton breakup reaction at 130 MeV deuteron energy are compared with the theoretical predictions obtained with a coupled-channel extension of the CD Bonn potential with virtual Delta-isobar excitation, without and with inclusion of the long-range Coulomb force. The Coulomb effect is studied on the basis of the cross-section data set, extended in this work to about 1500 data points by including breakup geometries characterized by small polar angles of the two protons. The experimental data clearly prefer predictions obtained with the Coulomb interaction included. The strongest effects are observed in regions in which the relative energy of the two protons is the smallest.Comment: 9 pages, 3 figures, submitted to Physics Letters

A comprehensive review on the applications of exosomes and liposomes in regenerative medicine and tissue engineering

Tissue engineering and regenerative medicine are generally concerned with reconstruct-ing cells, tissues, or organs to restore typical biological characteristics. Liposomes are round vesicles with a hydrophilic center and bilayers of amphiphiles which are the most influential family of na-nomedicine. Liposomes have extensive research, engineering, and medicine uses, particularly in a drug delivery system, genes, and vaccines for treatments. Exosomes are extracellular vesicles (EVs) that carry various biomolecular cargos such as miRNA, mRNA, DNA, and proteins. As exosomal cargo changes with adjustments in parent cells and position, research of exosomal cargo constitu-ents provides a rare chance for sicknesses prognosis and care. Exosomes have a more substantial degree of bioactivity and immunogenicity than liposomes as they are distinctly chiefly formed by cells, which improves their steadiness in the bloodstream, and enhances their absorption potential and medicinal effectiveness in vitro and in vivo. In this review, the crucial challenges of exosome and liposome science and their functions in disease improvement and therapeutic applications in tissue engineering and regenerative medicine strategies are prominently highlighted
