In all the cases analysed, the values of health hazard indices (HI, CR) for children are very low and well below the hazard threshold for each element.The search for renewable fuels or components which may improve or replace fossil fuels is an important step towards a sustainable future. In particular, the pine oleoresin produced by conifer trees, which is composed by turpentine oil and non-volatile rosin, may be transformed into alternative fuels. In this work, combustion of six molecules which can be obtained from oleoresin either by distillation (i.e., α- and β-pinene) or by further oxyfunctionalization (nopol, terpineol, myrtenol, and borneol) was studied to assess the potential of pine oleoresin as raw material for biofuels. Emission indices of the main pollutants (carbon monoxide-CO, unburned hydrocarbons-UHC, and nitrogen oxides-NOx) were obtained in non-premixed co-flow laminar flames of the oleoresin-derived molecules blended with n-heptane. The main characteristics of the flames (i.e., temperature and height) were also determined. Significant increase in flame temperature and reduction in CO and UHC emissions with respect to n-heptane were observed with nopol, terpineol, and myrtenol, along an increase in NOx emissions, suggesting an improvement in combustion performance. In addition, differences in emission indices, evidenced for these molecules (even between α- and β-pinene), suggest the importance of the molecular structure in the combustion reaction.Purpose Recombinant human erythropoietin (rHuEPO) is known to increase thrombotic risk in patients and might have similar effects in athletes abusing the drug. rHuEPO is prohibited by anti-doping legislation, but this risk has not been investigated thoroughly. This analysis was designed to evaluate whether rHuEPO impacts hemostatic profile and endothelial and platelet activation markers in trained subjects, and whether the combination with exercise affects exercise induced alterations. Methods This double-blind, randomized, placebo-controlled trial enrolled healthy, trained male cyclists aged 18-50 years. Participants were randomly allocated (11) to receive subcutaneous injections of rHuEPO (epoetin-β; mean dose 6000 IU per week) or placebo (0.9% NaCl) for 8 weeks. Subjects performed five maximal exercise tests and a road race, coagulation and endothelial/platelet markers were measured at rest and directly after each exercise effort. Results rHuEPO increased P-selectin (+ 7.8% (1.5-14.5), p = 0.02) and E-selectin (+ 8.6% (2.0-15.7), p = 0.01) levels at rest. see more Maximal exercise tests significantly influenced all measured coagulation and endothelial/platelet markers, and in the rHuEPO group maximal exercise tests led to 15.3% ((7.0-24.3%), p = 0.0004) higher E-selectin and 32.1% ((4.6-66.8%), p = 0.0207) higher Platelet factor 4 (PF4) levels compared to the placebo group. Conclusion In conclusion, rHuEPO treatment resulted in elevated E- and P-selectin levels in trained cyclists, indicating enhanced endothelial activation and/or platelet reactivity. Exercise itself induces hypercoagulability, and the combination of rHuEPO and exercise increased E-selectin and PF4 levels more than either intervention alone. Based on this, exercise potentially increases thrombotic risk, a risk that might be enhanced in combination with rHuEPO use.COVID-19 has profoundly modified the way healthcare is delivered. Jordan imposed lockdown and restrictive policies between March 17 and May 20, 2020. We aimed to assess the impact of such measures on thyroid cancer treatment plans. In the specified period, 12 patients were scheduled for surgery. Since papillary carcinoma was the preoperative diagnosis in all cases, radioactive iodine ablation (RIA) therapy was also planned 3-4 weeks following surgery after withdrawing thyroxine and achieving a thyroid stimulating hormone (TSH) level > 30 mU/L. Thyroxine withdrawal is the routine method applied for RIA in Jordan as it is less costly compared to the rapid method of exogenous stimulation using recombinant TSH. All surgical procedures were performed without delay since all patients were asymptomatic per flu-like illness and came from a region of low COVID-19 prevalence. These included total thyroidectomy (n = 11), bilateral therapeutic central compartment neck dissection (n = 7), lateral compartment neck dissection (n = 5). However, the RIA treatment plan was altered considerably according to the period in which they were operated. 6 out of the 7 patients operated in March changed to the stimulated method of RIA at a considerable additional extra cost. The seventh patient and the April patient opt to delay RIA until after lockdown. The remaining cases (operated in May) followed the usual withdrawal method as restrictions were due to an end. The restrictive measures applied during COVID-19 did not affect the safe and timely delivery of surgical care. However, it added a financial and psychological burden to the entire cancer management plan.Malignancies with extremely low incidences, such as less than 6 per 100,000 people annually, are defined as rare cancers. Approximately 200 malignancies are classified in this category, therefore the total number of patients with rare cancers is greater than that of patients with any single common cancer. However, because of the small numbers of patients, novel therapies have not been developed for individual rare cancers, and clinical outcomes remain dismal. Patient-derived cancer models are indispensable for both basic and pre-clinical studies, and their roles will increase in the era of post-genome medicine. Although patient-derived cancer models have long been used in oncology, they are not well developed for rare cancers. In the context of sarcoma, the presently available cell lines and xenograft models are limited and do not satisfy the needs of research. Indeed, the lack of effective therapies for rare cancers might be attributable to the paucity of adequate patient-derived cancer models for pre-clinical studies. To facilitate the establishment and availability of patient-derived rare cancer models, we need to create effective methods for model establishment, share the valuable clinical samples and established models, and implement guidelines to record the clinical data of donor patients and original tumors. Patient-derived rare cancer models are a public resource, and they should not be used exclusively but should rather be shared among the research community.
