A 51-year-old female with a history of radical mastectomy with axillary lymph node dissection, adjuvant chemotherapy and radiation for a breast cancer was referred to the emergency room due to cholangitis. A CT scan showed a common bile duct mass invading the duodenum. After bile draining, the investigations led to an undifferentiated carcinoma with positive hormonal receptors. The diagnosis of a breast cancer recurrence was established and the patient was commenced on taxane therapy.

The present study analyses the spatio-temporal variability of the macrozoobenthos from the intertidal zone of the Kneiss Islands (Gulf of Gabès, Tunisia). Samples were collected once from 34 stations, while seasonal variations were studied by sampling four times at 12 stations over the period 2013-2014. A total of 159 macrobenthos taxa associated with intertidal Zostera noltei beds are identified from the 34 stations, with a taxonomic dominance of crustaceans (32%), molluscs (29%) and annelids (27%). Abundance varies from 9244 to 36,844 ind·m-2 with a mean value of 14,346 ind·m-2. Analysis of the trophic structure shows that the majority of stations are strongly represented by carnivores (41%), followed by the non-selective deposit feeders (16%). Cluster analysis and multidimensional scaling allow identification of three main benthic assemblages based on species abundance, corresponding to different sediment types and organic matter contents. The seasonal variability in abundance, diversity and community structure is mainly due to spring and summer recruitment. The biotic indices (i.e. AMBI, BO2A and BENTIX) show that the intertidal area of Kneiss Islands exhibits a good ecological status.

Zn(1-x)CdxO films have been grown on (a-plane) and (r-plane) sapphire substrate by metal organic chemical vapor deposition. A maximum cadmium incorporation of 8.5% and 11.2% has been respectively determined for films deposited on a- and r-plane sapphire. The optical transmission spectra and energy band-gap equation established by Makino et al. were used to estimate the cadmium mole fraction of the solid solutions. Structural, morphological and optical properties of these films were examined using high resolution X-ray diffraction (HRXRD), atomic force microscopy (AFM) and room and low temperature photoluminescence (Pl) as Cd incorporation and employed substrate. X-ray diffraction study revealed that all films had wurtzite phase but solid solution grown on a-plane sapphire are polycrystalline with a preferred orientation along the [0001] direction and a-plane film are epitaxially grown on r-plane sapphire. AFM image show significant differences between morphologies depending on orientation sapphire substrate but no significant differences on surface roughness have been found. The near band-edge photoluminescence emission shifts gradually to lower energies as Cd is incorporated and reaches 2.916 eV for the highest Cd content (11.2%) at low temperature (20 K). The room temperature hall mobility decreases with the Cd incorporation but it is larger for Zn(1-x)CdxO grown on r-plane sapphire.

目的对一所三级保健学院医学中心的成年病人进行CT扫描后评估累积辐射剂量与射线诱发肿瘤的生存归因危险度(LAR)。方法本研究符合HIPAA,并且得到机构审查委员会的批准,免除了病人的知情同意。本组调查了31462例在2007年进行过CT检查的病人,在前后22年内共进行了190712次CT检查。根据每例病人CT有效照射剂量求和的方法来评估累积CT辐射剂量。应用电离辐射的生物学效应报告(BEIR)Ⅶ并根据研究对象的性别、年龄来评价其LAR。
