Objectives:Elevated circulating DNA(cirDNA)concentrations were found to be associated with trauma or tissue damage which suggests involvement of inflammation or cell death in post-operative cirDNA *** carried out the first prospective,multicenter study of the dynamics of cirDNA and neutrophil extracellular trap(NETs)markers during the perioperative period from 24 h before surgery up to 72 h after curative surgery in cancer ***:We examined the plasma levels of two NETs protein markers[myeloperoxidase(MPO)and neutrophil elastase(NE)],as well as levels of cirDNA of nuclear(cir-nDNA)and mitochondrial(cir-mtDNA)origin in 29 colon,prostate,and breast cancer patients and in 114 healthy individuals(HI).Results:The synergistic analytical information provided by these markers revealed that:(i)NETs formation contributes to post-surgery conditions;(i)post-surgery cir-nDNA levels were highly associated with NE and MPO in colon cancer[r=0.60(P<0.001)and r=0.53(P<0.01),respectivelyl,but not in prostate and breast cancer;(i)each tumor type shows a specific pattern of cir-nDNA and NETs marker dynamics,but overall the pre-and post-surgery median values of cir-nDNA,NE,and MPO were significantly higher in cancer patients than in ***:Taken as a whole,our work reveals the association of NETs formation with the elevated cir-nDNA release during a cancer patient's perioperative period,depending on surgical procedure or cancer *** contrast,cir-mtDNA is poorly associated with NETs formation in the studied perioperative period,which would appear to indicate a different mechanism of release or suggest mitochondrial dysfunction.

亚里士多德的形质学说对西方哲学的发展有着深远影响,并在中世纪通过经院哲学家而获得了更加系统性的表述。16—17世纪,在西学东渐的背景下,耶稣会士将其引入中国。利玛窦初步介绍了形式因和质料因,而最终高一志对形质说有比较系统的介绍,肯定物理世界的重要性,甚至意识到形质说对中国思想可以做出很大的贡献。《天主实义》《寰有诠》《性学觕述》《万物真原》和《寰宇始末》展示了晚明耶稣会士为适应中国思想对形质说所做的调整。

The thyroid, an endocrine gland located at the base of the neck, produces thyroid hormones (triiodothyronine (T3) and thyroxine (T4)). The production of these hormones is possible by iodine and other nutrients such as selenium and certain vitamins. To assess the thyroid disturbances in the mountain population of Benin, a survey was conducted in Natitingou, a mountain town located in the department of Atacora, in the northwest of Benin, on a sample of thirty (30) adults (15 men and 15 women), most of whom are educated. The results of the questionnaire revealed that 43% of the surveyed population acknowledged having knowledge on the mentioned subject and have dietary habits based on the consumption of seafood, and also legumes (20%). The examination of the serum results of the dosage of T3, T4 and TSH hormones revealed cases of thyroid disturbances in the region (36.32% in men and 44.98% in women). The analysis of a comparative table including the “VEDALAB Easy Reader+” and five (05) other readers, presents the performance, reading techniques, principles, advantages and disadvantages of each device. Pending further studies, some recommendations were made at the end of this study to the academic authorities regarding probable cases of dysthyroidism for which additional examinations are required and an awareness for the improvement of dietary habits.
