    Design, synthesis and antimycobacterial activity of novel nitrobenzamide derivatives
    (Elsevier, 2018) Wang, Hongjian; Lv, Kai; Li, Xiaoning; Wang, Bo; Wang, Apeng; Tao, Zeyu; Geng, Yunhe; Wang, Bin; Huang, Menghao; Liu, Mingliang; Guo, Huiyuan; Lu, Yu; Medicine, School of Medicine
    We report herein the design and synthesis of a series of novel nitrobenzamide derivatives. Results reveal that many of them display considerable in vitro antitubercular activity. Four N-benzyl or N-(pyridine-2-yl)methyl 3,5-dinitrobenzamides A6, A11, C1 and C4 have not only the same excellent MIC values of <0.016 μg/mL against both drug-sensitive MTB strain H37Rv and two drug-resistant clinical isolates as PBTZ169 and the lead 1, but also acceptable safety indices (SI > 1500), opening a new direction for further development.

    Design, synthesis and antitubercular evaluation of benzothiazinones containing a piperidine moiety
    (Elsevier, 2018-05) Lv, Kai; Tao, Zeyu; Liu, Qian; Yang, Lu; Wang, Bin; Wu, Shuo; Wang, Apeng; Huang, Menghao; Liu, Mingliang; Lu, Yu; Medicine, School of Medicine
    We herein report the design and synthesis of benzothiazinones containing a piperidine moiety as new antitubercular agents based on the structure feature of IMB-ZR-1 discovered in our lab. Some of them were found to have good in vitro activity (MIC < 1 μg/mL) against drug-susceptible Mycobacterium tuberculosis H37RV strain. After two set of modifications, compound 2i were found to display comparable in vitro anti-TB activity (MIC < 0.016 μg/mL) to PBTZ169 against drug-sensitive and resistant mycobacterium tuberculosis strains. Compound 2i also showed acceptable PK profiles. Studies to determine PK profiles in lung and in vivo efficacy of 2i are currently under way.

    Exploring Parental Influence on the Progression of Alcohol Use in Mexican-Heritage Youth: a Latent Transition Analysis
    (Springer, 2016-02) Shin, YoungJu; Lee, Jeong-Kyu; Lu, Yu; Hecht, Michael; Department of Communication Studies, School of Liberal Arts
    Mexican-heritage youth are members of the fastest growing minority group and are at particular risk for substance use including alcohol consumption. Youth face numerous risk factors including positive descriptions of substance use on media and peer offers that are potentially ameliorated by parental anti-substance use socialization efforts. Guided by primary socialization theory and the theory of planned behavior, the present study posited eight research questions to identify discrete subgroups/patterns of Mexican-heritage youth alcohol use behavior and parental influence on youth outcomes. Longitudinal survey data (n = 1147) from youth in 29 public schools located in Phoenix, Arizona, were collected over 3 years. Latent class and transition analyses identified four discrete subgroups characterized by response patterns of alcohol use behaviors and perceptions in Mexican-heritage youth: (1) non-drinker, (2) potential drinker, (3) experimenter, and (4) regular drinker. Targeted parent-child communication about alcohol and parental monitoring were found to be significant predictors for youth alcohol use. Research implications and future directions are suggested.

    Pregnancy-Related Information Seeking in Online Health Communities: A Qualitative Study
    (Springer, 2021) Lu, Yu; Zhang, Zhan; Min, Katherine; Luo, Xiao; He, Zhe; Engineering Technology, School of Engineering and Technology
    Pregnancy often imposes risks on women's health. Consumers are increasingly turning to online resources (e.g., online health communities) to look for pregnancy-related information for better care management. To inform design opportunities for online support interventions, it is critical to thoroughly understand consumers' information needs throughout the entire course of pregnancy including three main stages: pre-pregnancy, during-pregnancy, and postpartum. In this study, we present a content analysis of pregnancy-related question posts on Yahoo! Answers to examine how they formulated their inquiries, and the types of replies that information seekers received. This analysis revealed 14 main types of information needs, most of which were "stage-based". We also found that peers from online health communities provided a variety of support, including affirmation of pregnancy, opinions or suggestions, health information, personal experience, and reference to health providers' service. Insights derived from the findings are drawn to discuss design opportunities for tailoring informatics interventions to support consumers' information needs at different pregnancy stages.
