Infection with Toxoplasma gondii (T. gondii) during the pregnant period and its potentially miserable outcomes for the fetus, newborn, and even adult offspring continuously occur worldwide. People acquire infection through the consumption of infected and undercooked meat or contaminated food or water. T. gondii infection in pregnant women primarily during the gestation causes microcephaly, mental and psychomotor retardation, or death. Abnormal pregnancy outcomes are mainly associated with regulatory T cell (Treg) dysfunction. Tregs, a special subpopulation of T cells, function as a vital regulator in maintaining immune homeostasis. Tregs exert a critical effect on forming and maintaining maternal-fetal tolerance and promoting fetal development during the pregnancy period. Forkhead box P3 (Foxp3), a significant functional factor of Tregs, determines the status of Tregs. In this review, we summarize the effects of T. gondii infection on host Tregs and its critical transcriptional factor, Foxp3.

This article highlights issues pertaining to the Sephardim ([-im] is the masculine plural Hebrew ending and Sepharad is the Hebrew name for Spain. Sephardim thus literally means the Jews of Spain) in Sarajevo from the time of their arrival in the Ottoman Empire in the late fifteenth century until the present day. I describe the status quo for the Sephardi minority in post-Ottoman Sarajevo, in the first and second Yugoslavia, and in today's post-Communist Sarajevo, the capital of Bosnia and Herzegovina. The objective is to shed light on how historic preconditions have influenced identity formation as it expresses itself from a Sephardic perspective. The aim is moreover to generate knowledge of the circumstances that affected how Sephardim came to understand themselves in terms of their Jewish identification. I present empirical findings from my semi-structured interviews with Sarajevo Sephardim of different generations (2015 and 2016). I argue that while none of the interlocutors conceive of Jewish identification as divergent from halachic interpretations of matrilineal descent, they moreover propose other conceptions of what it means to be Jewish, such as celebrating Shabbat and other Jewish holidays, and other patterns of socialization. At the same time, these individuals also assert alternative forms of being Bosnian, one that includes multiple ethnicities, and multiple religious ascriptions. This study elucidates a little-explored history and sheds light on the ways in which historical conditions have shaped contemporary, layered framings of identification among Sarajevo's current Jewish population. This article is relevant for those interested in contemporary Sephardic Bosnian culture and in the role and function of ideology in creating conditions for identity formation and transformation.

Abstract As vast strides are being made in the management and treatment of multiple myeloma (MM), recent interests are increasingly focusing on understanding the development of the disease. The knowledge that MM develops exclusively from a protracted phase of monoclonal gammopathy of undetermined significance provides an opportunity to study tumor evolution in this process. Although the immune system has been implicated in the development of MM, the scientific literature on the role and status of various immune components in this process is broad and sometimes contradictory. Accordingly, we present a review of cellular immune subsets in myelomagenesis. We summarize the current literature on the quantitative and functional profiles of natural killer cells and T-cells, including conventional T-cells, natural killer T-cells, γδ T-cells and regulatory T-cells, in myelomagenesis. Our goal is to provide an overview of the status and function of these immune cells in both the peripheral blood and the bone marrow during myelomagenesis. This provides a better understanding of the nature of the immune system in tumor evolution, the knowledge of which is especially significant considering that immunotherapies are increasingly being explored in the treatment of both MM and its precursor conditions.

The Senate Reference is ultimately a decision about how democratic decision making ought to be conducted when the role and function of fundamental democratic institutions are themselves at stake. This case stands for the idea that unilateral decision making by Parliament is not permitted even if from a substantive standpoint the government’s proposals are “more democratic” than the status quo. Consultative elections and senatorial term limits, for example, would arguably make the Senate a more representative and accountable body. Yet the Court held that such changes are subject to the Constitution’s general amending formula, which means that Parliament cannot implement these changes on its own. This article suggests that the Court’s interpretation of the amending procedures is based upon a deeper democratic commitment to ensuring dialogue and deliberation between and among the relevant stakeholders. The Court’s approach has benefits and drawbacks. By setting itself up as the exclusive arbiter of the Constitution’s “internal architecture” and the primary decision-maker as to what constitutes an institution’s “fundamental role and nature”, the Court has enhanced its own authority over the evolution of the constitutional order while significantly narrowing the possibilities for constitutional change. While the Court’s approach has the undeniable effect of making large-scale institutional reform difficult (if not impossible), the alternative is arguably worse. If it were possible for the government to unilaterally reform democratic institutions, then it could unilaterally reform them in an anti-democratic direction as well.
