Furthermore, wide geographic variations in rates and trends of mortality from these diseases have been shown since the early 1950s ^{8, 9} and for incidence and case fatality from IHD by the WHO MONICA Project in the mid-1980s ¹⁰.</p> <p>There is a controversy in the relationship between early life conditions and mortality at later life. Several studies have shown the association between IHD and adverse living conditions in early life ^11-15, but not always ^{16, 17}. For stroke, some studies have observed this relationship ^{14, 18}, whereas others have not ^{12, 15}. Time trends of stomach cancer also differ between populations and the role of living conditions on trends is not yet fully understood ¹⁹.</p> <p>In this paper, the results of my previous population-based time-series studies will be discussed that aimed to describe trends in mortality between subsequent cohorts in relation to living conditions in early life of these cohorts ^{20, 21}. Cohort-wise trends of IHD, stroke, and stomach cancer mortality of populations in seven European countries &ndash;i.e., Denmark, England and Wales, Finland, France, the Netherlands, Norway and Sweden- have been assessed and it has been determined whether these trends were correlated with developments in infant mortality rate (IMR) at the time of birth of the subsequent cohorts.</p> <p>Generally, an overall decline in mortality from these three diseases from 1950 to 2005 in all countries, for all ages and both men and women have been observed, with the important exception of a period epidemic of IHD in 1950 to 1970. From a cohort perspective, we observed steady declines for between cohorts born between 1860 and 1939 in most causes, again with the exception of IHD.</p><p><strong>Key Words:</strong> Early life conditions, Mortality trends, Ischemic Heart Diseases, Stroke, Stomach cancer, Europe</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/100http://ijpm.mui.ac.ir/index.php/ijpm/article/download/100/322

The adoption of a 95 cm cutoff for male abdominal obesity was crucial in the understanding of factors for cardiometabolic risk. The prevalence of MetS, type-2 diabetes and coronary heart disease (CHD) are high, alike in Iranians. The TARF study demonstrated that systemic low-grade inflammation and oxidative stress are a major determinant of cardiometabolic risk in the population at large, and involves the female sex to a greater extent than the male. As a result of this, impaired anti-inflammatory and atheroprotective function developed in large segments of middle-aged and elderly obese individuals emerging as dysfunction of apolipoprotein A-I and HDL particles. This dysfunction is currently a major driver cardiometabolic risk in Turkish adults leading to substantial excess diabetes and CHD. Separate algorithms for diabetes and CHD were derived that improved the risk prediction of these diseases.</p> <p>The author strongly suspects that such dynamics in the development of diabetes and CHD exist in Western adults prone to impaired glucose tolerance, and evidence is accumulating also regarding general Iranian adults. These issues posing a vast threat on public cardiometabolic health will have to be recognized with the purpose of not delaying implementation of measures for the improvement in cardiometabolic risk, especially in women.</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/99http://ijpm.mui.ac.ir/index.php/ijpm/article/download/99/323

Human embryonic stem cell (hESC) lines are derived from the inner cell mass (ICM) of developing blastocysts and have a broad clinical potential, and they can be used to obtain germ cells. hESCs have been classified in to three classes based on their epigenetic state. &nbsp;The goal of this project is to epigenetically reprogram Class II and Class III cell lines to Class I (na&iuml;ve state), and to in vitro differentiate potent hESCs to primordial germ cells (PGCs). Recent evidence suggests that 3-deazaneplanocin A (DZNep) is a global histone methylation inhibitor which selectively inhibits trimethylation of lysine 27 on histone H3K27, and it is an epigenetic therapeutic for cancer. The characteristics of DZNep lead us to hypothesize that it is a good candidate to epigenetically reprogram hESC cells to the Class I. Also, we used sodium butyrate, shown in previous studies to up-regulate the expression of germ cell specific markers. We used these two drugs to produce epigenetically stable hESC lines. X-Chromosome inactivation has been used as a tool to follow the reprogramming process. We have used immunostaining and western blot as methods to follow this re-programming qualitatively and quantitatively. The preliminary results showed that hESC cells treated with these two drugs showed dramatic tendency to lose H3K27me3 marker.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/97http://ijpm.mui.ac.ir/index.php/ijpm/article/download/97/325

Cognitive dysfunction is of immense importance as a long term complication of brain injuries. Numerous studies are planned to investigate the effect of potential remedy on preventing or halting secondary post-traumatic brain damages,which results in cognitive as well as general function impairments.The current study aimed to provide reliable scales to gauge patient&rsquo;s functional level in specific domain to ensure reliable results in Iran.</p> <p class="abstract"><strong>Methods:</strong> We selected three general and cognitive function scales [Glasgow Outcome Scale Extended (GOSE), Galveston Amnesia and Orientation Test (GOAT), Disability Rating Scale (DRS)] used extensively worldwide, and converted them to Farsi language. To assess their validity and reliability, we implemented them on a group of head injured Iranian patients.</p> <p class="abstract"><strong>Results:</strong> Factor analysis revealed 5 independent factors for GOAT with total distribution variance of 80.2%. For DRS, 3 independent factors came out that consisted 92.3% of variance. GOAT and DRS Farsi versions in our study also had satisfactory correlation coefficient using Pierson correlation matrix. Regarding the reliability, the Cronbach&rsquo;s alpha index was 78.2% for GOAT and 90.5% for DRS. Factor analysis was not feasible for GOSE. However, Kappa coefficient was used to estimate its validity, which was 68%.</p> <p class="abstract"><strong>Conclusions:</strong> This study inferred that our Farsi version of DRS and GOAT functional scales are certainly appropriate for Iranian head injured patients. Our GOSE Farsi-converted scale showed good validity, though it is still required to be more evaluated for reliability in future attempts. This scale can help in&nbsp; prevention of secondary brain damages after trauma.</p> <p class="abstract"><strong>Keywords:</strong> Closed Head Injury, Cognitive function, General function, Rehabilitation.</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/83http://ijpm.mui.ac.ir/index.php/ijpm/article/download/83/327

A number of PrEP trials are evaluating the safety and effectiveness of PrEP in men who have sex with men (MSM) and other populations at risk for HIV, and results will be available from this first generation of efficacy trials over the next few years. Here we review the rationale for orally-administered antiretrovirals for prevention, and outline issues the first generation trials will address as well as questions that may be addressed in future studies.
