Tumor-stroma crosstalk leads to a tumor-promoting microenvironment. In this milieu, extracellular vesicles (EVs) are protagonists in cell-cell communication. Despite thyroid cancer being the most common endocrine malignancy, the contribution of the tumor microenvironment to thyroid cancer progression is still largely underexplored. We focused on the role of thyroid tumor cell-fibroblast interaction and EVs as mediators of tumor-stroma interplay, in the promotion of thyroid tumor aggressiveness. Thyroid tumor (TPC-1, 8505c) or non-tumor thyroid cells (NThyOri) were co-cultured with human fibroblasts (Fb). Thyroid cell migration was investigated by the wound-healing assay and actin-network staining. Cell-CD147 expression was characterized by flow cytometry. EVs, obtained by ultracentrifugation of conditioned media (CMs), were characterized by transmission electron-microscopy and CD81 and CD147 expression. Metalloproteinases (MMPs) were evaluated by zymography in CMs. A migratory phenotype was triggered in thyroid tumor cells treated with CMs from Fb or from Fb-thyroid tumor cell co-cultures. Fb-thyroid cell co-cultures induced the secretion of proMMP9 and proMMP2, and led to a significant MMP2 activation in CMs. Fb, thyroid cells and Fb-thyroid cell co-cultures released EVs, and remarkably, EVs released by Fb-thyroid tumor cell co-cultures induced the secretion of proMMP2 and the expression of MMP2 from normal Fb. selleck chemical A significant CD147 expression was demonstrated in Fb-thyroid tumor cell derived EVs. These findings reveal the role of Fb and thyroid tumor cell-Fb interaction in the promotion of a microenvironment suitable for thyroid tumor progression. Moreover, they highlight for the first time the role of thyroid tumor cell-Fb interaction in the production of specialized EVs.Background Rates of exclusive breastfeeding in Australia lag behind international targets. Reasons for non-exclusive breastfeeding are poorly understood. Research aims To describe demographic profiles of participants reporting different feeding practices, and reasons for not exclusively breastfeeding to 6 months. Methods Demographics for 2888 mothers (5340 children) and reasons for 1879 mothers (3018 children) from the Mothers and Their Children's Health Study (a sub-study of the Australian Longitudinal Study on Women's Health) were examined using descriptive statistics and multivariable regression. Results Only 34.4% of children were exclusively breastfed to 6 months. Five non-exclusive feeding practices were identified never breastfed (3.9%), breastfed less then 6 months (20.8%), and breastfed to 6 months but had formula (6.8%), solids (24.5%), or both formula and solids (9.7%). Mothers of children who received less then 6 months of human milk were more likely to have a lower education, be overweight/obese, smoke, and live in cities (compared to mothers of children exclusively breastfed). Reasons for never breastfeeding and for breastfeeding less then 6 months were primarily insufficient milk and breastfeeding difficulties (e.g., latching issues). Reasons for introducing solids were primarily cues for solids (e.g., showing interest). Reasons for formula were insufficient milk and practical considerations (e.g., return to work). Reasons for both solids and formula were diverse, including insufficient milk, weaning cues, and practical considerations. Conclusions Mothers who did not exclusively breastfeed to 6 months were a heterogeneous group, indicating that both targeted and universal strategies are required to increase rates of exclusive breastfeeding. Support should encompass the broad range of feeding practices.Background Pityriasis lichenoides chronica, a papulosquamous disorder often considered a subtype of pityriasis lichenoides. It is considered a clonal T-cell disorder, which may be associated with cutaneous T-cell lymphoma that may develops in response to foreign antigens. Case presentation We present a 38-year-old male patient with ankylosing spondylitis who was on treatment with etanercept. After 8 weeks of treatment, the patient presented with scaly erythematous papules, on the back and arms. He was diagnosed clinically with pityriasis lichenoides chronica. Conclusion Pityriasis lichenoides chronica should be included among the broad clinical spectrum of chronic inflammatory skin diseases which may occur during treatment with TNF-alpha antagonists.

The molecular factors involved in this process are poorly understood. Micro RNAs (miRNAs) are small non-coding RNAs that inhibit mRNA transcription. MiRNAs, which can participate in the benefits of exercise to health, circulate in plasma in extracellular particles (EP). Horses that undergo endurance racing are an excellent model to study the impact of long-duration/low intensity exercise in plasma EP miRNAs. Objectives To evaluate the effects of 160 km endurance racing on horse plasma extracellular particles and their miRNA population. Study design Cohort study. Methods We collected plasma from 5 Arabian horses during five time-points of an endurance ride. Extracellular particles were purified from plasma and characterised by electron microscopy, resistive pulse sensing (qNano), and western blotting. Small RNAs were purified from horse plasma EP, and sequencing was performed. Results Endurance racing increased EP concentration and average diameter compared to before the race. Western blotting showed a high concentration of extracellular vesicles proteins 2 h after the race, which returned to baseline 15 h after the race. MicroRNA differential expression analysis revealed increasing levels of eca-miR-486-5p during and after the race, and decreasing levels of eca-miR-9083 after the end. Conclusions This study adds new data about the variation in plasma EP concentrations after long-distance exercise and brings new insights about the roles of exercise-derived EP miRNAs during low-intensity endurance exercise.
