作者： bruno AMELINE Evelyne CHOLET UCMTF the French Textile Machinery Manufacturers’ Association

China Textile: Could you please talk about the status quo of textile industry, especially textile machinery industry, in France? Mr. AMELINE & Ms. CHOLET: The French Textile Machinery Manufacturers’ Association groups 30 companies. The total annual turnover is above 1 billion US Dollars. 2018 was at record levels. We have a good visibility for 2019 thanks to the order backlogs at the beginning of the year but, this year, order intakes are slower due to the international turmoil. Geographically there are very clear trends which will not change in the next years whatever the uncertainties which can appear.

Effect of different starch sources in a raw meat-based diet on fecal microbiome in dogs housed in a shelter

Summary evidence on the effects of varicocele treatment to improve natural fertility in subfertile men

引用

Asian Journal of Andrology 2016年第2期18卷 239-245,J0005页

作者： bruno C Tiseo Sandro C Esteves Marcello S Cocuzza Department of Urology University of Sao Paulo Av. Dr. Eneas de Carvalho Aguiar 255 7 andar - Sala 710F Sao Paulo 05403-000 Brazil ANDROFERT Center for Male Reproduction Av. Dr. Heitor Penteado 1464 Campinas Sao Paulo 13075-460 Brazil.

The objective of this review was to summarize the evidence concerning the benefit of varicocele treatment to improve natural fertility in subfertile males. We also analyzed the effect of varicocele treatment on conventional semen parameters and sperm functional tests. An electronic search to collect the data was performed using the PubMed/MEDLINE databases until July 2015. Data pooled from a variety of study designs indicate that varicocelectomy improves semen parameters in the majority of the treated men with clinical varicocele and abnormal semen parameters regardless of the chosen surgical method. Surgical varicocele repair was beneficial not only for alleviating oxidative stress-associated infertility but also to improve sperm nuclear DNA integrity. However, given the low magnitude of the effect size in sperm DNA integrity, further research is needed to elucidate its clinical significance. Conflicting results on the effect of varicocele treatment on natural fertility seem to be due to heterogeneous study designs and, more importantly, patient selection criteria. When these issues are controlled, current evidence indicates that treatment of subclinical varicocele is not warranted, as it does not seem to improve fertility. On the contrary, fair evidence indicates that varicocele treatment should be offered to infertile patients with palpable varicocele and abnormal semen parameters. This evidence supports the current guidelines issued by the American Urological Association and European Association of Urology, which state that varicocele treatment should be offered to male partners of infertile couples presenting for evaluation with clinical varicocele and semen parameters alterations.

Monitoring and factors affecting levels of airborne and water bromoform in chlorinated seawater swimming pools

引用

Journal of Environmental Sciences 2017年第8期29卷 262-270页

作者： Jean-Luc Boudenne Julien Parinet Carine Demelas Tarek Manasfi bruno Coulomb Aix Marseille Univ CNRS LCE13331 Marseille France Arises 94700 Maisons-Alfort France

Water and air quality of eight seawater swimming pools using chlorine disinfection was measured during four sampling campaigns, spread on one full-year, and in four thalassotherapy centers located in Southeast of France. Concentrations of trihalomethanes（THMs） in air and in water as well as concentrations of parameters, including nonpurgeable organic carbon（NPOC）, free residual chlorine（Cl_f）, pH, Kjeldhal Nitrogen（KN）, salinity,conductivity, bromide ions and, water and air temperature, were measured. Water and air samples were collected in triplicates morning — at the opening of the pools —, noon and night — at the closing of the pools —, in summer and winter. Data analysis was performed by Principal Component Analysis（PCA） and rotated component matrix, from both data quality and other parameters such as TOC, aromaticity（UV_（254））, pH, hygrometry, and free residual chlorine（Cl_f）. This statistical analysis demonstrates a high correlation between TOC, Cl_fand UV_（254） and THM levels found in air and water, particularly for the major ones（CHBr_3in water：300.0 μg/L mean, 1029.0 μg/L maximum; CHBr_3 in air： 266.1 μg/m^3 mean,1600.0 μg/m^3 maximum, and CHClBr_2 in water： 18.9 μg/L mean, 81.0 μg/L maximum;CHClBr_2 in air： 13.6 μg/m^3 mean, 150.0 μg/m^3maximum）. These high levels of bromoform（CHBr_3） are particularly worrisome in such health institutions, even these levels do not exceed the Permissible Exposure Limit（PEL） of 5 mg/m^3 as an 8 hour time-weighted average currently fixed by various administrations, such as Occupational Safety and Health Administration（OSHA）.
