抗癌药物的研究:4-氯苯氧乙酰胺衍生物的合成

Since compounds Ⅲ and Ⅳ possess retinoid-like action and analogues of Ⅰ inhibit some cancer cells ,seventeen derivatives of chlorophenoxy acetamide were synthesized.Of the seven compounds screened ,two exhibit cytostatic activity(1 and　2).Mass spectra showeda　special expulsion of SO2 and CO from the sulfonamide compounds,Nuclear magnetic resonancesplitting patterns of these compounds also showed interesting features.     

Beyond “patient-provider race matching.” Black midwives clarify a vision for race-concordant care to achieve equity in Black perinatal health: A commentary on “Do Black birthing persons prefer a Black health care provider during birth? Race concordance in birth”

Racial concordance has been identified as a potential strategy to improve the perinatal health of Black women and birthing people by mitigating implicit bias and improving mutual trust, healthy communication, and satisfaction. In a recent article published in BIRTH: Issues in Perinatal Care, Bogdan-Lovis et al. surveyed 200 Black women to determine whether they possessed a race and gender practitioner preference for their birth practitioner and examined whether race and gender concordance was associated with greater birth satisfaction and perceived respect, trust, practitioner competence, empathy, and use of inclusive communication. In this commentary, written by a group of Black midwives, we respond to the study and offer a vision for race-concordant care that encompasses cultural safety provided in a community-based setting.
