某些物种的蚜虫中,雌性个体成熟较晚,可以认为是雄性个体的“侄女”。当冬季即将来临,剩余时间就不能满足发育需求时,发育延迟了,发育延迟应当也终止了雌性功能上的投资。然而,最近的证明表明,雌性功能的投资并不停止。这种未预料到的发现可能归因于一种进化限制因素,归因于雄性个体在不同年龄阶段对配偶的竞争,或归因于不能预测导致随机非遗传多型性的最后期限。本文讨论了这三种可能性,最后一种可能性由于暂时性地解释了雌性功能中的连续投资而是一种可取的解释。尽管延缓发育和开始繁殖的最后期限常见于那些生活在严寒地区的、雌性发育迟缓的蚜虫,本文的观点也适合于一个性别成熟较晚的、具有繁殖最后期限的任何一个蚜虫物种。

This study reports two observations of heart fail.re diagnosed in the context of SARS-CoV 2 infection in chil.ren at the University Hospital.Center of l.brevil.e, Gabon. l.ng considered exempted from serious forms of Covid-19 infection, the fatal.evol.tion of one of the two cases proves that there is an interest for a more rigorous approach in their management in a pandemic context. The mul.isystem infl.mmatory syndrome associated with this virus in chil.ren can be responsibl. for cardiac manifestations that can be l.fe-threatening. Earl. diagnosis and treatment are necessary to reduce mortal.ty. However, this approach is made difficul. in our regions by the l.mited biomedical.equipment and the absence of essential.therapies as noted in these two observations.

The adsorption of 2,6-naphthal.nedicarboxyl.c acid(NDCA)mol.cul.s on the Ag(110),Cu(110),and Ag(111)surfaces at room temperature has been studied by means of scanning tunnel.ing microscopy(STM).Further supporting resul.s were obtained using X-ray photoel.ctron spectroscopy(XPS)and soft X-ray absorption spectroscopy(XAS).On the Ag(110)support,which had an average terrace width of onl. 15 nm,the NDCA mol.cul.s form extended one-dimensional.1-D)assembl.es,which are oriented perpendicul.r to the step edges and have l.ngths of several.hundred *** shows that the assembl.es have a l.rge tol.rance to monatomic surface steps on the Ag(110)*** observed behaviour is expl.ined in terms of strong intermol.cul.r hydrogen bonding and a strong surface-mediated directional.ty,assisted by a sufficient degree of mol.cul.r backbone *** contrast,the same kind of step-edge crossing is not observed when the mol.cul.s are adsorbed on the isotropic Ag(111)or more reactive Cu(110)*** Ag(111),simil.r 1-D assembl.es are formed to those on Ag(110),but they are oriented al.ng the step *** Cu(110),the carboxyl.c groups of NDCA are deprotonated and form coval.nt bonds to the surface,a situation which is al.o achieved on Ag(110)by anneal.ng to 200°*** resul.s show that the formation of particul.r sel.-assembl.d mol.cul.r nanostructures depends significantl. on a subtl. bal.nce between the adsorbate-adsorbate and adsorbate-substrate interactions and that kinetic factors pl.y an important rol..
