Opis:
Endocrine disruptors interfere with hormonal action through receptors and signaling pathways, but receptor crosstalk involved in the actions of endocrine disruptors has not yet been well documented. This review summarizes what is known about the actions of endocrine disruptors through receptor crosstalk, focusing on three model cases: crosstalk involving the estrogen receptor, the androgen receptor, and the thyroid hormone receptor. Here, crosstalk is categorized as bidirectional or unidirectional, with the latter category further subdivided into ligand-dependent or -independent crosstalk. More research needs to be done to develop a clearer understanding of the involvement of receptor crosstalk in cell signaling that is induced by endocrine disruptors. This understanding will help to develop in vitro and in silico assays that can replace animal tests.

Opis:
Upslope and downslope walking are basic activities necessary for normal daily living in community, and they impose greater joint load on the lower extremities than during level walking. Thus, the purpose of this study was to quantify the resultant and shear forces in the hip and knee joints during slope walking. Methods: Twelve healthy volunteers were evaluated when walking under level and 10° up- and downslope conditions. Three-dimensional gait analysis was conducted using a 7-camera optoelectronic motion analysis system combined with a force plate to measure ground reactive force. Joint forces in the hip and knee joints were estimated using musculoskeletal model simulation. Results: Results showed that the resultant hip force was increased significantly to 117.2% and 126.9%, and the resultant knee force was increased to 133.5% and 144.5% in up- and downslope walking, respectively, compared to that of level walking. Furthermore, increased shear force in the hip and knee joints was noted during both slope walking conditions. Conclusions: This information may be beneficial for therapists advising elderly people or patients with osteoarthrosis on an appropriate gait pattern, gait assistive devices, or orthoses according to their living environment.
