Dear Editor, The scarce number of secondary spermatocytes in human seminiferous tubules and the complexity of analyzing chromosomes at metaphase II are the main causes of the limited knowledge we have about chromosome characteristics at this stage. In this study, we have performed a comprehensive analysis of meiotic abnormalities in metaphase II spermatocytes combining Leishman＇s staining protocols and multiplex fluorescent in situ hybridization procedures. Results indicated that infertile individuals showed different susceptibilities to meiotic abnormalities in secondary spermatocytes without a preferentially effect on any particular chromosome.

Plastics are ubiquitous. Their role as a cost-effective, chemically stable, versatile multipurpose material precluded early attempts to regulate plastic wastes and facilitated the, now widespread, planetary contamination. Left to slow UV decay and thermooxidative weathering, large plastics chip away into less than 5 mm fragments, or microplastics, which, in turn, can degrade further into nanoplastics. In the manufacturing process, several components,such as catalysts, solvents, stabilizers。

Landscape changes are known to exacerbate the impacts of climate change. As such, understanding the combined effect of climate and landscape on agroecosystems is vital if we are to maintain the fimction of agroecosystems. This study aimed to elucidate the effects of agricultural landscape complexity on the microclimate and thermal tolerance of an aphid pest to better understand how landscape and climate may interact to affect the thermal tolerance of pest species within the context of global climate change. Meteo- rological data were measured at the landscape level, and cereal aphids （Sitobion avenae, Metopolophium dirhodum and Rhopalosiphum padi） sampled, from contrasting landscapes （simple and complex） in winter 2013/2014 and spring 2014 in cereal fields of Brittany, France. Aphids were returned to the laboratory and the effect of landscape of origin on aphid cold tolerance （as determined by CTmin） was investigated. Results revealed that local landscape complexity significantly affected microclimate, with simple homogenous landscapes being on average warmer, but with greater temperature variation. Landscape complexity was shown to impact aphid cold tolerance, with aphids from complex land- scapes being more cold tolerant than those from simple landscapes in both winter and spring, but with differences among species. This study highlights that future changes to land use could have implications for the thermal tolerance and adaptability of insects. Fur- thermore, not all insect species respond in a similar way to microhabitat and microclimate, which could disrupt important predator-prey relationships and the ecosystem service they provide.

Domino liver transplantation（LT）, using livers from familial amyloidotic polyneuropathy（FAP） patients, is a well described technique useful to expand donor pool. One of the main difficulties of this type of LT arises from the necessity to share the vascular pedicles between the graft and the donor. The most important challenge resides in restoring a proper hepatic venous outflow in the FAP-liver *** is specially challenging when using the piggy-back technique, because the hepatic stumps may be too short. To overcome this issue, surgeons explored several techniques using different types of venous grafts. We describe a new technical option by using an arterial graft from the deceased donor. By using both iliac arteries a long graft is created and sutured as needed to the hepatic vein stump. We describe herein this new technique employed in a domino liver recipient who underwent retransplantation for ischemic cholangitis. The procedure was performed using the piggy-back technique; the venous stump of the FAP liver was reconstructed with the arterial graft. The patient had uneventful postoperative and mid-term hepatic function, and anastomosis was patent 24 months after LT.

Dear Editor, In interphase nuclei, chromosomes occupy specific localizations called chromosome territories （CTs）. Distribution of CTs has been related to chromosome size and gene density and is known to influence gene expression.~ This pattern of organization appears to be a widespread nuclear feature, both in somatic and germ ceils.
