Re-thinking Teaching About Atrocity: Human Rights Comparative History and Critical Pedagogy

This paper will explore re-framing historic atrocity and its relationship to Holocaust and Genocide education. The origins of genocide studies and its links to Holocaust studies will be traced to discuss the impact of new scholarship and framings on genocide education in the classroom.

Detection of surfactant proteins A and D in human tear fluid and the human lacrimal system

PURPOSE: To evaluate the expression and presence of surfactant protein (SP) A and SP-D in the lacrimal apparatus, at the ocular surface, and in tears in healthy and pathologic states. METHODS: Expression of mRNA for SP-A and SP-D was analyzed by RT-PCR in healthy lacrimal gland, conjunctiva, cornea, and nasolacrimal ducts as well as in a spontaneously immortalized conjunctival epithelial cell line (HCjE; IOBA-NHC) and a SV40-transfected cornea epithelial cell line (HCE). Deposition of SP-A and SP-D was determined by Western blot, dot blot, and immunohistochemistry in healthy tissues, in tears, aqueous humor, and in sections of different corneal abnormalities (keratoconus, herpetic keratitis, and Staphylococcus aureus-based ulceration). Cell lines were stimulated with different cytokines and bacterial components and were analyzed for the production of SP-A and SP-D by immunohistochemistry. RESULTS: The presence of SP-A and SP-D on mRNA and protein levels was evidenced in healthy lacrimal gland, conjunctiva, cornea, and nasolacrimal duct samples. Moreover, both proteins were present in tears but were absent in aqueous humor. Immunohistochemistry revealed the production of both peptides by acinar epithelial cells of the lacrimal gland and epithelial cells of the conjunctiva and nasolacrimal ducts, whereas goblet cells revealed no reactivity. Healthy cornea revealed weak reactivity on epithelial surface cells only. In contrast, SP-A and SP-D revealed strong reactivity in patients with herpetic keratitis and corneal ulceration surrounding lesions and in several immigrated defense cells. Reactivity in corneal epithelium and endothelium was also seen in patients with keratoconus. Cell culture experiments revealed that SP-A and SP-D are produced by both epithelial cell lines without and after stimulation with cytokines and bacterial components. CONCLUSIONS: These results show that SP-A, in addition to SP-D, is a peptide of the tear film. Based on the known direct and indirect antimicrobial effects of collectins, the surfactant-associated proteins A and D seem to be involved in several ocular surface diseases.

Immunomodulatory lipids in plants: plant fatty acid amides and the human endocannabinoid system

Since the discovery that endogenous lipid mediators show similar cannabimimetic effects as phytocannabinoids from CANNABIS SATIVA, our knowledge about the endocannabinoid system has rapidly expanded. Today, endocannabinoid action is known to be involved in various diseases, including inflammation and pain. As a consequence, the G-protein coupled cannabinoid receptors, endocannabinoid transport, as well as endocannabinoid metabolizing enzymes represent targets to block or enhance cannabinoid receptor-mediated signalling for therapeutic intervention. Based on the finding that certain endocannabinoid-like fatty acid N-alkylamides from purple coneflower ( ECHINACEA spp.) potently activate CB2 cannabinoid receptors we have focused our interest on plant fatty acid amides (FAAs) and their overall cannabinomodulatory effects. Certain FAAs are also able to partially inhibit the action of fatty acid amide hydrolase (FAAH), which controls the breakdown of endocannabinoids. Intriguingly, plants lack CB receptors and do not synthesize endocannabinoids, but express FAAH homologues capable of metabolizing plant endogenous N-acylethanolamines (NAEs). While the site of action of these NAEs in plants is unknown, endogenous NAEs and arachidonic acid glycerols in animals interact with distinct physiological lipid receptors, including cannabinoid receptors. There is increasing evidence that also plant FAAs other than NAEs can pharmacologically modulate the action of these endogenous lipid signals. The interference of plant FAAs with the animal endocannabinoid system could thus be a fortunate evolutionary cross point with yet unexplored therapeutic potential.

Concepts for Contemporary Social Work: Globalization, Oppression, Social Exclusion, Human Rights, Etc.

The society wrestles with mass social change congruent with economic globalization and the communications revolution. This change creates new challenges for the social work profession in the areas of social and economic justice. This article analyzes the terminology of the new global era, words that signify a paradigm shift in outlook, most of them a reaction to the new authoritarianism of the age. Globalization, oppression, social exclusion, human rights, harm reduction, and restorative justice are the representative terms chosen.

Sex Trafficking of Minors as a Human Rights Issue

The following commentary serves as a response to the article, “Sex Trafficking of Minors in the U.S.: Implications for Policy, Prevention and Research,” drawing the important, though not often mentioned, connection between the sex trafficking of minors and human rights. The commentary argues that child trafficking has been inadequately addressed due to its relative invisibility, a lack of knowledge about human rights, and a lack of discourse about the human rights issues involved in sexual trafficking. As such, in the current day, the recognition that women and girls who are sexually exploited by traffickers are victims has seemingly been forgotten. The commentator commends the authors of “Sex Trafficking of Minors in the U.S.: Implications for Policy, Prevention and Research” for their work to better understand the characteristics of minor sex trafficking victims, which will play an important role in fighting deadly misperceptions about the victims, educating others about this lethal human rights violation, and finding ways to care for those victims who are rescued.
