The Animalistic Gullet and the Godlike Soul: Reframing Sacrifice in Midrash Leviticus Rabbah

This article proposes an analysis of two homiletic units in the Palestinian Midrash Leviticus Rabbah, which revolve around biblical chapters pertaining to sacrifices. A theme that pervades these units is that of eating as an animalistic activity that often entails moral depravity. In contrast, the act of sacrificing is constructed in these units as one in which one is willing to give up one's own nourishment, and in a sense one's own “soul,” in order to offer it to God. Many of the motifs used to vilify eating in the Midrash can be traced in moralistic Greek, Roman, and early Christian diatribes preaching for moderation in eating or for asceticism; the homilists in Leviticus Rabbah, however, utilize these popular motifs in order to present sacrifice as the spiritual contrary of eating, and thus to give the obsolete practice of sacrifice cultural cachet and compelling meanings

Unperformed Rituals in an Unread Book

What is the significance of an unperformed ritual? And what is the meaning of an unread text? The intuitive answer, that unperformed rituals and unread texts have no meaning, is clearly wrong in the case of Leviticus. The rituals depicted in its text mean a great deal, because Jews, Samaritans and Christians continue to ritualize Leviticus as part of their scriptures. Leviticus’s status as the third book of scripture has remained virtually uncontested throughout the histories of these three religions, despite the fact that people do not observe many of its offering instructions or, among Christians, even read much of its text. It retains its place among the sacred scrolls and books reproduced by each religion. Therefore if the job of commentary is to explain the meaning of Leviticus, it cannot stop with the book’s words, much less their original referents. The meanings of Leviticus have been broadcast by the sounds of its words and the sight of the books and scrolls that contain it as much as by semantic interpretations of its contents, which have themselves been manifested in ritual and legal performances as well as in sermons and commentaries. Out of all this emerges the phenomenon of scripture, of which Leviticus is an original and integral part

An overlooked connection: serotonergic mediation of estrogen-related physiology and pathology

BACKGROUND: In humans, serotonin has typically been investigated as a neurotransmitter. However, serotonin also functions as a hormone across animal phyla, including those lacking an organized central nervous system. This hormonal action allows serotonin to have physiological consequences in systems outside the central nervous system. Fluctuations in estrogen levels over the lifespan and during ovarian cycles cause predictable changes in serotonin systems in female mammals. DISCUSSION: We hypothesize that some of the physiological effects attributed to estrogen may be a consequence of estrogen-related changes in serotonin efficacy and receptor distribution. Here, we integrate data from endocrinology, molecular biology, neuroscience, and epidemiology to propose that serotonin may mediate the effects of estrogen. In the central nervous system, estrogen influences pain transmission, headache, dizziness, nausea, and depression, all of which are known to be a consequence of serotonergic signaling. Outside of the central nervous system, estrogen produces changes in bone density, vascular function, and immune cell self-recognition and activation that are consistent with serotonin's effects. For breast cancer risk, our hypothesis predicts heretofore unexplained observations of the opposing effects of obesity pre- and post-menopause and the increase following treatment with hormone replacement therapy using medroxyprogesterone. SUMMARY: Serotonergic mediation of estrogen has important clinical implications and warrants further evaluation

Influence of resistance training on serum lipid and lipoprotein concentrations in young men and women

De 21ste eeuw is de eeuw van de stad: sinds het begin van het millennium woont meer dan de helft van de wereldbevolking insteden. Nadenken over de stad is dan ook van groot belang. Wat is een stad eigenlijk? Welke rol spelen economie, politiek en ruimte in de stedelijke ontwikkeling? Hoe beleven bewoners en bezoekers de stad? Hoe gaan stadsbestuurders om met pluriformiteit en duurzaamheid? En waarin verschillen steden in het Globale Zuiden van die in Europa? Deze en tal van andere vragen worden in dit inleidende studieboek beantwoord aan de hand van theoretische inzichten, recente onderzoeksresultaten en praktijkvoorbeelden. Zo maakt de lezer kennis met het denken van Foucault, Simmel en Sennett, terwijl hij tevens een bezoek brengt aan tuindorpen, smart cities en de straten van Yogyakarta. Visies op de stad is bestemd voor studenten van universiteiten, hogescholen en trainingsinstituten, maar ook voor iedereen die meer wil weten over de fascinerende wereld van de stad
