This study examined socio-demographic differences in acculturation patterns among early immigrant and second-generation Arab Americans, using data from 120 participants who completed a Web-based study. Although sex, age, education, and income did not significantly relate to the acculturation process, respondents who were female and those who were married reported greater Arab ethnic identity and religiosity. Striking differences were found based on religious affiliation. Christian patterns of acculturation and mental health were consistent with acculturation theory. For Muslims, however, integration was not associated with better mental health, and religiosity was predictive of better family functioning and less depression. The results of this study suggest unique acculturation patterns for Christian and Muslim subgroups that can better inform future research and mental health service.

Americans of Middle Eastern and North African (MENA) descent in the United States have been historically understudied, in part due to limitations of racial classification systems that typically include MENA under the broad umbrella of White. As a result, enormous gaps in knowledge about health and mental health disparities exist, with broad public health significance. In particular, there is an urgent need to attend more specifically to MENA Americans’ experiences of cumulative racial–ethnic trauma, which occurs at every level of their social ecologies. This article offers a conceptual model of cumulative racial–ethnic trauma to represent the unique experiences of the MENA American population. Traumatic factors at the macrolevel include historical trauma, pervasive institutional discrimination, and a hostile national context. These factors interact with one another and further impact microlevel traumatic experiences related to interpersonal discrimination and microaggressions, as well as struggles with identity and recognition. The deleterious impacts of these experiences may include a ubiquitous sense of insecurity, hopelessness, and alienation among MENA American individuals, in addition to more specific mental health and physical health concerns. It also compromises the overall well-being of the MENA American population in terms of belonging versus alienation, freedom versus restriction, and opportunities versus disadvantage. We discuss how the model can help to create a foundation for future inquiry and contribute to intervention efforts to find effective ways to support resilience and thriving for the MENA American population.

Like other minority groups in North America, Muslim Americans have been largely ignored in the psychological literature. The overwhelming pressures faced by this group, including surveillance, hate crimes, and institutional discrimination, stimulate an urgent need for psychologists to better understand and ensure the well-being of this population. This article reviews challenges in conducting research with Muslim Americans in order to offer recommendations for culturally sensitive approaches that can enhance the growth of future scholarship. We first contextualize this endeavor by assessing trends in psychological scholarship pertinent to Muslims in North America over the past two decades. A total of 559 relevant publications were identified through a PsycINFO database search. The 10 years post 9/11 saw a more than 900% increase in the annual number of publications, paralleling a national interest in the Muslim American community subsequent to the World Trade Center attacks. Researchers who conducted these studies faced numerous barriers, including unclear definition of the target sample, unavailability of culturally sensitive measures, sampling difficulties, and obstacles to participant recruitment. To navigate these challenges, we provide a framework for effective research design along the continuum of the research process from study conceptualization to dissemination of results. The challenges and recommendations are illustrated with examples from previous studies.

Adipose stem cells (ASCs) have recently emerged as a more viable source for clinical applications, compared to bone-marrow mesenchymal stromal cells (BM-MSCs) because of their abundance and easy access. In this study we evaluated the regenerative potency of ASCs compared to BM-MSCs. Furthermore, we compared the dielectric and electro-kinetic properties of both types of cells using a novel Dielectrophoresis (DEP) microfluidic platform based on a printed circuit board (PCB) technology. Our data show that ASCs were more effective than BM-MSCs in promoting neovascularization in an animal model of hind-limb ischemia. When compared to BM-MSCs, ASCs displayed higher resistance to hypoxia-induced apoptosis, and to oxidative stress-induced senescence, and showed more potent proangiogenic activity. mRNA expression analysis showed that ASCs had a higher expression of Oct4 and VEGF than BM-MSCs. Furthermore, ASCs showed a remarkably higher telomerase activity. Analysis of the electro-kinetic properties showed that ASCs displayed different traveling wave velocity and rotational speed compared to BM-MSCs. Interestingly, ASCs seem to develop an adaptive response when exposed to repeated electric field stimulation. These data provide new insights into the physiology of ASCs, and evidence to their potential superior potency compared to marrow MSCs as a source of stem cells.
