... Premise of the study: Research on the subject of heterostyly is often traced back to 1877 when Charles Darwin published the landmark book The Different Forms of Flowers on Plants of the Same Species. This book synthesized heterostyly research at the time, much of which Darwin conducted, and it continues to be a major contribution to the study of the breeding system. In this book, Darwin discussed ...
... Both missionaries and government policymakers in colonial Zimbabwe consciously identified agriculture as an important avenue in establishing broader paradigms of explanation. Missionary promotion of new farming practices inevitably challenged the existing spiritual landscape by insisting that rationalized individual labor could overcome powerful natural forces. This article examines various facets ...
... The order Rickettsiales (Alphaproteobacteria) is a well-known group containing obligate endocellular prokaryotes. The order encompasses three families (Rickettsiaceae, Anaplasmataceae, and Holosporaceae) and a fourth, family-level cluster, which includes only one candidate species, "Candidatus Midichloria mitochondrii," as well as several unnamed bacterial symbionts. The broad host range exhibited ...
... Here we investigated the bacterial endosymbionts of weevils of the genus CURCULIO: From all four species of Curculio weevils examined, a novel group of bacterial gene sequences were consistently identified. Molecular phylogenetic analyses demonstrated that the sequences formed a distinct clade in the Gammaproteobacteria, which was not related to previously known groups of weevil endosymbionts such ...
... Click Cu(I)-catalyzed polymerizations of diynes that contained ester linkages and diazides were performed to produce polyesters (click polyesters) of large molecular weights [(~1.0-7.0) x 10⁴], that contained main-chain 1,4-disubstitued triazoles in excellent yields. Incorporation of triazole improved the thermal properties and magnified the even-odd effect of the methylene chain length. We also f ...

Failure to recognize that many standard control rats and mice used in biomedical research are sedentary, obese, glucose intolerant, and on a trajectory to premature death may confound data interpretation and outcomes of human studies. Fundamental aspects of cellular physiology, vulnerability to oxidative stress, inflammation, and associated diseases are among the many biological processes affected ...
mothers; Mexican Americans; cultural heritage; food choices; foodways; traditional foods; family relations; meals (menu)
Abstract:
... This paper offers a discussion of A Taco Testimony: Meditations on Family, Food, and Culture , the memoir by Chicana writer Denise Chávez. I argue that Chávez experiences the act of eating and preparing Mexican food as a critique of racism and as a way for her to assert her Mexicanidad or "Mexicanness." More importantly, it is her mother's food that instills Chávez with pride in her ethnic heritag ...
... We examine the importance of the maintenance and reinvention of tradition to the food choices described by Mexican-American focus group participants recruited from nutritional health settings in central Texas. The pressures experienced while coping with changes in their food environment, such as shift-work and working outside the home, and transformations experienced in the food production system, ...
