Available online at: http://jbe.tums.ac.ir Conditional methods of adjustment are often used to quantify the effect of the exposure on the outcome. As a result, the stratums-specific risk ratio estimates are reported in the presence of interaction between exposure and confounder(s) in the literature, even if the target of the intervention on the exposure is the total population and the interacti...
Marginal zone (MZ) B cells are absent in CD19(-/-) mice. Possible causes include an intrinsic defect in B cells and/or a secondary defect in the extrinsic MZ microenvironment as a result of changes in B cell differentiation in mice lacking CD19. Cells in the MZ also include MZ macrophages (MZM) and MZ dendritic cells (DC). Although CD19 is only expressed on B cells, SIGN-R1(+) MZM are absent an...
Epigenetic mechanisms, including DNA methylation, play an important role in not only the development and maturation of normal cells, but also the development and progression of malignant cells. In this edition of Blood, Arribas et al show that DNA methylation profiling identifies 2 subtypes of splenic marginal zone lymphoma with different clinical and genetic features. These findings provide an...
The exact analysis of optimal ordering policies for periodic-review perishable inventory systems is challenging because their high-dimensional state space arising from multiple interrelated decisions over many periods and age distributions on-hand products. We develop a new marginal framework to approximate this complex multiple-decision model into single-decision with an externality term, whic...
BACKGROUND There is wide regional variation in the predominant treatment for unruptured cerebral aneurysms. We investigated the association of elective surgical clipping and endovascular coiling with mortality, readmission rate, length of stay, and discharge to rehabilitation. METHODS AND RESULTS We performed a cohort study involving patients with unruptured cerebral aneurysms, who underwent ...
Background and Aims: One of the most important challenges for dentists is providing a crown with appropriate marginal fit and gap. The 135-degree tooth preparation found to have some advantages such as technical ease and appropriate finish line record. Despite the advantages of 135-degree tooth preparation, scant research has been done in this area. Therefore, the aim of this study was to compa...
