International regulatory uses of acute systemic toxicity data and integration of new approach methodologies.

Chemical regulatory authorities around the world require systemic toxicity data from acute exposures via the oral, dermal, and inhalation routes for human health risk assessment. To identify opportunities for regulatory uses of non-animal replacements for these tests, we reviewed acute systemic toxicity testing requirements for jurisdictions that participate in the International Cooperation on Alternative Test Methods (ICATM): Brazil, Canada, China, the European Union, Japan, South Korea, Taiwan, and the USA. The chemical sectors included in our review of each jurisdiction were cosmetics, consumer products, industrial chemicals, pharmaceuticals, medical devices, and pesticides.

The importance of metrological tools to implementation of alternative method OECD TG 428.

Usually, if percutaneous absorption tests are conducted in accordance with OECD Guideline 428, in vitro determination is accepted by mainly regulatory agencies. In this paper, we focus on the lack of comparability of the results regarding the permeation parameter/flow rate, although it is widely discussed in the literature. This work sought to evaluate the absorption of caffeine using Franz-type diffusion cell with porcine ear skin samples, varying the storage duration and the way to handle them.

A Body of One's Own: From Self-Cutting to the Cuts of Separation in an Adolescent Suffering From Traumatic Early Abandonments.

The treatment of adolescents suffering from early traumatic experiences inescapably involves the encounter with patients' concrete use of their bodies and actions. The clinical history of an adolescent girl reveals the relationship between traumatic transgenerational abandonments and self-cutting in the transference-countertransference relationship. Initially the patient's body and actions were the only way to communicate experiences that could not be conveyed in words and represented: the "skin for two" of the original psychosomatic envelope needed to be wounded, cut, broken concretely.

Focus on family functioning in anorexia nervosa: new perspectives using the Lausanne Trilogue Play.

31 families of female adolescents affected by anorexia nervosa (AN) and 20 of girls with emotional and behavioral disorders participated in a semi-standardized videotaped game: the Lausanne Trilogue Play (LTPc). We aimed to clarify if there is a typical AN family profile and if the LTPc procedure could predict the risk of developing AN. We confirmed that AN families exhibit dysfunctional alliances.

The Overt and Hidden Use of Animal-Derived Products in Alternative Methods for Skin Sensitisation: A Systematic Review.

methods that can replace animal testing in the identification of skin sensitisers are now a reality. However, as cell culture and related techniques usually rely on animal-derived products, these methods may be failing to address the complete replacement of animals in safety assessment. The objective of this study was to identify the animal-derived products that are used as part of methods for skin sensitisation testing.
