Social influence of adult children on parental health behavior among South Asian immigrants: findings from the MASALA (Mediators of Atherosclerosis in South Asians Living in America) study.

Examine the social influence of adult children on the cardiovascular-related health behaviors of older South Asian (SA) immigrants to inform lifestyle interventions. This mixed-methods study used data from an ancillary study of social networks (2014-2018) in the Mediators of Atherosclerosis in South Asians Living in America cohort. Phase 1 was a quantitative analysis of self-reported diet and physical activity among SA adults ( = 448, mean age = 58 years, SD 8.

Recruitment and retention of US South Asians for an epidemiologic cohort: Experience from the MASALA study.

Introduction: There are few longitudinal studies about South Asians (SAs) and little information about recruitment and retention approaches for this ethnic group.

Methods: We followed 906 SAs enrolled in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) cohort for 5 years. Surviving participants were invited for a second clinical exam from 2015 to 2018.

Social network body size is associated with body size norms of South Asian adults.

Aims: To examine the association between social network body size and body size norms in South Asian adults.

Methods: Participants (n = 766) from the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study (2014-2018) provided detailed information about their five closest network members. Participants' perceptions of their network members' body sizes, their own body size (self-body size), and a healthy body size for men and women (body size norms) were assessed using the Stunkard 9-figure scale.

Mediators of Atherosclerosis in South Asians Living in America: Use of Web-Based Methods for Follow-Up and Collection of Patient-Reported Outcome Measures.

Background: A key challenge for longitudinal cohort studies is follow-up and retention of study participants. Participant follow-up in longitudinal cohort studies is costly and time-consuming for research staff and participants.

Objective: This study determined the feasibility and costs of using Web-based technologies for follow-up and collection of patient-reported outcomes in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study.

Qualitative Process Evaluation of a Community-Based Culturally Tailored Lifestyle Intervention for Underserved South Asians.

Introduction There are few examples of effective cardiovascular disease prevention interventions for South Asians (SAs). We describe the results of a process evaluation of the South Asian Heart Lifestyle Intervention for medically underserved SAs implemented at a community-based organization (CBO) using community-based participatory research methods and a randomized control design (n = 63). Method Interviews were conducted with 23 intervention participants and 5 study staff using a semistructured interview guide focused on participant and staff perceptions about the intervention's feasibility and efficacy.

Regulators of the Bacillus subtilis cydABCD operon: identification of a negative regulator, CcpA, and a positive regulator, ResD.

The cydABCD operon of Bacillus subtilis encodes products required for the production of cytochrome bd oxidase. Previous work has shown that one regulatory protein, YdiH (Rex), is involved in the repression of this operon. The work reported here confirms the role of Rex in the negative regulation of the cydABCD operon.

CcpA causes repression of the phoPR promoter through a novel transcription start site, P(A6).

The Bacillus subtilis PhoPR two-component system is directly responsible for activation or repression of Pho regulon genes in response to phosphate deprivation. The response regulator, PhoP, and the histidine kinase, PhoR, are encoded in a single operon with a complex promoter region that contains five known transcription start sites, which respond to at least two regulatory proteins. We report here the identification of another direct regulator of phoPR transcription, carbon catabolite protein A, CcpA.
