Background: Breast cancer is the dominant cancer in women in both developed and developing countries. The objective of this study was to assess the knowledge, attitudes, practices and factors associated with early breast cancer screening among women in the Municipality of Abomey-Calavi in Benin. Methods: This was a cross-sectional, descriptive, analytical study with prospective data collection from October 1 to 8, 2018, involving 1740 women in the Municipality of Abomey-Calavi, aged 18 years or older and selected by WHO four-stage random cluster sampling. Consenting women who were mentally competent, 18 years of age or older at the time of the survey, and residing continuously in the Municipality of Abomey-Calavi for the last six months prior to the survey were included. On the other hand, women who belonged to a breast cancer prevention service, women in whom secondary screening was noted, or non-consenting women were not included. The initial minimum size was estimated by the Schwartz formula with a cluster effect of k = 2. Information was collected by questionnaire survey, entered with Epidata 3.1. Fr and analyzed with R Studio 3.5.1. software. Results: The mean age of the women surveyed was 32.0 ± 11.5 years with a range of 18 and 71 years. Regarding knowledge, the clinical manifestation known by the majority of women was the presence of a nodule (68.50%). In the series, 1308 (75.17%) declared having heard about breast cancer once before, either on the radio, television or from friends and 726 (55.50%) had heard about breast cancer screening. Five hundred and twelve (70.52%) of the 726 who had heard of breast cancer said they knew that breast cancer could be screened earlier. Breast self-examination was the most cited screening method (67.58%). The disease is of natural origin according to 37.84% of them. Regarding attitudes and practices, the prevalence of early breast cancer screening was 12.93%, of which 11.67% declared that they had checked themselves to kno

GPU-driven Scalable Parser for OBJ Models

引用

journal of Computer Science & Technology 2018年第2期33卷 417-428页

作者： Sunghun jo Yuna Jeong Sungkil Lee department of Software Sungkyunkwan University Suwon 16419 Korea

This paper presents a scalable parser framework using graphics processing units （GPUs） for massive text-based files. Specifically, our solution is designed to efficiently parse Wavefront OBJ models texts of which specify 3d geometries and their topology. Our work bases its scalability and efficiency on chunk-based processing. The entire parsing problem is subdivided into subproblems the chunk of which can be processed independently and merged seamlessly. The within-chunk processing is made highly parallel, leveraged by GPUs. Our approach thereby overcomes the bottlenecks of the existing OBJ parsers. Experiments performed to assess the performance of our system showed that our solutions significantly outperform the existing CPU-based solutions and GPU-based solutions as well.

A new enone (CH 3CO C( p NO 2C 6H 4COO)=CH S C 6H 4( p Br) 5, C 17 H 12 NBrO 5S, M r =422.25) was synthesized and its crystal structure was determined by X ray diffraction method. The crystal belongs to the monoclinic system, space group P2 1/c with a=6.4121(9), b=12.804(1), c=20.998(2) , β=94.884(9)°, V=1717.1(3) 3, Z=4, d c =1.633 g/cm 3, μ (Mo Kα )=2.542 mm -1 , F( 000)=848. Final R =0.0428 and wR =0.0916 for 3335 reflections with I>2σ(I) . The title compound exists as Z isomer with p bromothiophenolate and o nitrobenzoate groups cis arranged around asymmetrical centre. This observation suggests that the substitution of thiophenolate for bromine is a stereoselective step.

Pancreatitis, panniculitis, and polyarthritis syndrome caused by pancreatic pseudocyst: A case report

引用

World journal of Clinical Cases 2019年第18期7卷 2808-2814页

作者： Sungho jo Sanghyun Song department of Surgery Dankook University Hospital Dankook University College of Medicine

BACKGROUNd Panniculitis, polyarthritis, and pancreatitis (PPP) syndrome is a triad comprising an extremely rare extra-pancreatic complication of pancreatic disease. Herein, we describe a patient with PPP syndrome caused by fistula formation between the inferior vena cava (IVC) and pancreatic pseudocyst. CASE SUMMARY A 64-year-old man visited the hospital with bilateral leg pain that began one week prior. He had no specific diseases, except hypertension. His vital signs were normal. Blood test revealed the following findings: White blood cell count, 28690/μL;amylase level, 9055 U/L;lipase level, 2089 U/L;and C-reactive protein level, 12.94 mg/dL. Computed tomography of the pancreas revealed recent acute pancreatitis. Nonsteroidal anti-inflammatory drugs were administered with no improvement. After steroid administration, pain slightly improved. Skin lesions were diagnosed as panniculitis. Bone scan and knee magnetic resonance imaging revealed osteoarthritis and bone marrow infarctions. Surgical treatment was considered;total pancreatectomy with splenectomy was performed. A pseudocyst was present posterior to the head of the pancreas, forming a fistula with the suprarenal IVC. After surgery, amylase and lipase levels decreased. However, the patient died of an uncontrolled infection on the 13th postoperative day. CONCLUSION PPP syndrome should be suspected when accompanied by skin and joint lesions. delays in diagnosis could have catastrophic consequences.

Inheritance patterns of secondary symbionts during sexual reproduction of pea aphid biotypes

引用

Insect Science 2014年第3期21卷 291-300页

作者： Jean Peccoud joêl Bonhomme Frédérique Mahéo Manon de la Huerta Olivier Cosson Jean-Christophe Simon INRA Institut de Génétique Environnement et Protection des Plantes (UMR IGEPP) Domaine de La Motte 35653 le Rheu cedex France

Herbivorous insects frequently harbor bacterial symbionts that affect their ecol- ogy and evolution. Aphids host the obligatory endosymbiont Buchnera, which is requiredfor reproduction, together with facultative symbionts whose frequencies vary across aphid populations. These maternally transmitted secondary symbionts have been particularlystudied in the pea aphid, Acyrthosiphon pisum, which harbors at least 8 distinct bacterial species （not counting Buchnera） having environmentally dependent effects on host *** particular, these symbiont species are associated with pea aphid populations feeding on specific plants. Although they are maternally inherited, these bacteria are occasionallytransferred across insect lineages. One mechanism of such nonmaternal transfer is paternal transmission to the progeny during sexual reproduction. To date, transmission of secondarysymbionts during sexual reproduction of aphids has been investigated in only a handful of aphid lineages and 3 symbiont species. To better characterize this process, we investigatedinheritance patterns of 7 symbiont species during sexual reproduction of pea aphids through a crossing experiment involving 49 clones belonging to 9 host-specialized biotypes, and117 crosses. Symbiont species in the progeny were detected with diagnostic qualitative PCR at the fundatrix stage hatching from eggs and in later parthenogenetic *** found no confirmed case of paternal transmission of symbionts to the progeny, and we observed that maternal transmission of a particular symbiont species （Serratia symbiotica）was quite inefficient. We discuss these observations in respect to the ecology of the pea aphid.
