Comparative Fatty Acid Composition of Eggs from White Bass Fed Live Food or Commercial Feed

We evaluated the influence of two broodstock feeding practices on fatty acid composition and viability of eggs in white bass Morone chrysops. The two dietary groups tested were (1) white bass females fed a commercially formulated feed (crude protein, 45%; crude fat, 16%) and (2) white bass females maintained on live food (fathead minnow Pimephales promelas and golden shiners Notemigonus crysoleucas). Significant differences existed between the dietary treatments in egg fatty acid levels. Eggs of white bass fed live food contained more 11-octadecenoic acid (18:1[n-7]), α-linolenic acid (18:3[n-3]), arachidonic acid (20:4[n-6]), docosahexaenoic acid (22:6[n-3]), and total n-3 fatty acids than eggs of fish fed formulated feed. Conversely, eggs of fish fed the formulated feed contained more oleic acid (18:1[n-9]), linoleic acid (18:2[n-6]), and total monoeic acids. Female white bass fed live food produced significantly more viable eggs (68.0 ± 2.0%) at 48 ± 2 h posthatch than did females fed the commercial feed (57.0 ± 2.0% [mean ± SD]). We found that the egg fatty acids of white bass are significantly affected by the diet of the female and suggest that the fatty acid composition of eggs contribute to overall reproductive success and viability of progeny. More information on the nutrient requirements of piscivorous broodstock is needed to allow feeds to be formulated to enhance the viability of eggs and fry

Radiological evaluation of industrial residues for construction purposes correlated with their chemical properties

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this recordThis study characterises the naturally occurring radionuclide (NOR) contents of a suite of secondary raw materials or industrial residues that are normally disposed of in landfills or lagoons but now are increasingly used in green concretes. This includes ashes from a variety of industrial processes and red mud from aluminium production, as well as air pollution control residue and cement kiln dust. The chemical composition of the samples was determined with X-ray fluorescence spectroscopy (XRF). The Ra-226, Th-232 and K-40 activity concentrations were obtained by gamma spectrometry, and the results were compared with recently published NOR databases. The correlation between the NOR contents and the main chemical composition was investigated. The radioactive equilibrium in the U-238 chain was studied based on the determination of progeny isotopes. The most commonly used calculation methods (activity concentration index and radium equivalent concentration) were applied to classify the samples. The radon exhalation rate of the samples was measured, and the radon emanation coefficient was calculated. Significant correlation was found between the NORs and certain chemical components. The massic exhalation demonstrated a broad range, and it was found that the emanation coefficients were significantly lower in the case of the residues generated as a result of high-temperature combustion processes. The results showed a weak correlation between the Ra-226 concentration and the radon exhalation. This emphasises that managing the Ra-226 content of recycled material by itself is not sufficient to control the radon exhalation of recycled materials used in building products. The investigated parameters and their correlation behaviour could be used to source apportion materials found during the process of landfill mining and recovery of material for recycling.European Union Horizon 202

The characteristics of bilateral breast cancer patients

Introduction. Bilateral breast cancer (BBC) consists of 2–12% all cases of breast carcinoma. In relation to time between the first and second cancer diagnosis, the synchronous (s-BBC) or metachronous (m-BBC) bilateral breast cancer is defined. Material and methods. The clinicopathologic characteristics of 303 patients treated between 1963 and 2014 for bilateral breast cancer was presented. Synchronous BBC was diagnosed in 70 patients (23.1%) and remaining 233 patients (76.9%) developed metachronous BBC. Patients with m-BBC in comparison to s-BBC were younger (mean age: 51.4 vs 60.6 years), the positive family cancer history was rare (36.7% vs 48.5%), and more frequently these patients were before menopause (65.7% vs 44.3%). While the lobular type of breast cancer which consisted of 6.6% cases in first breast and 8.9% cases of second carcinomas, more frequently was presented in s-BBC (8.6%) in comparison to m-BBC (6%). Results. The mean time of follow up was 174 months. The 5- and 10-year overall survival rates were 89.3% and 76.1%, respectively. The presence of s-BBC connected with worse prognosis; the 5- and 10-year overall survival were 93.1% and 82% for m-BBC and 76.4% and 52.1% for s-BBC (p = 0.00244, log-rank test).Introduction.

Synchronous malignancies in patients with breast cancer

Introduction. The continuously improving cancer detection at an early stage and improving survival rates have been observed and, therefore, patients are predisposed to detection of multiple primaries. It has been reported that the incidence of multiple primaries in breast cancer patients ranges from of 4% to 17%. Materials and methods. A group of 112 breast cancer patients with synchronous malignancies was presented. They constituted 0.09% of patients (118,952 cases) who were treated for breast cancer at the same time period, and made up 3.5% of all patients (3,176 cases) with multiple primary cancers, and 21.7% of all patients (517 cases) with breast cancer who developed multiple primaries. Results. The most frequent type of synchronous primary malignancy was breast cancer (63.4%) and 90.1% of them were diagnosed at the same time or within one month following the first breast cancer diagnosis. Among cases of non-breast synchronous primaries, female genital organ malignancies were predominant (36.6%). Synchronous breast cancer was diagnosed significantly earlier than non-breast cancers (mean time was 0.4 and 1 month, respectively, p = 0.0123). Better results in the group with synchronous contralateral breast cancer in comparison to synchronous breast and non-breast cancer were observed (5-year overall survival rates were 90.9% and 66.3%, respectively, and 5-year disease-free survival rate — 62.5% and 51.3%, respectively)

The ethics of human-animal relationships and public discourse: A case study of lions bred for their bones

Conservation and natural resource management are increasingly attending the ethical elements of public decisions. Ethical considerations are challenging, in part, because they typically require accounting for the moral consideration of various human and nonhuman forms of life, whose interests sometimes conflict (or seem to conflict). A valuable tool for such evaluations is the formal analysis of ethical arguments. An ethical argument is a collection of premises, logically interrelated, to yield a conclusion that can be expressed in the form, “We ought to…” According to the rules of logic, a conclusion is supported by an argument if all its premises are true or appropriate and when it contains no mistaken inferences. We showed how the formal analysis of ethical arguments can be used to engage stakeholders and decision-makers in decision-making processes. We summarised the method with ten specific guidelines that would be applicable to any case. We illustrated the technique using a case study focused on captive-bred lions, the skeletons of which form part of an international trade to supply traditional medicine markets in Southeast Asia with felid bones. As a matter of public policy, the practice is a complicated nexus of concerns for entrepreneurial freedom, wildlife conservation, and the fair treatment of animals

Elastic-to-plastic crossover below the peak effect in the vortex solid of YBa2Cu3O7 single crystals

We report on transport and ac susceptibility studies below the peak effect in twinned YBa2Cu3O7 single crystals. We find that disorder generated at the peak effect can be partially inhibited by forcing vortices to move with an ac driving current. The vortex system can be additionally ordered below a well-defined temperature where elastic interactions between vortices overcome pinning-generated stress and a plastic to elastic crossover seems to occur. The combined effect of these two processes results in vortex structures with different mobilities that give place to history effects.Comment: 4 pages, 4 figures.

Typical medullary breast carcinoma: clinical outcomes and treatment results

Typical medullary breast carcinoma (T-MBC) accounts for less than 1% of all malignant breast neoplasms, and immu­nohistochemically is characteristic of “triple-negative” breast carcinoma. The purpose of this study was to describe the clinical characteristics and treatment results for patients with T-MBC treated at a single institution, and discuss the controversial aspects of this very rare form of breast cancer. Analyses was performed in 120 patients with T-MBC who were treated between 1970 and 2005. These cases represent 1.1% of all (11 270) patients treated for breast cancer during this period. According to TNM classification, 26 patients (21.6%) were in stage I, 80 patients (66.7%) in stage II and 14 (11.7%) in stage III of clinically advanced breast cancer. Involved axillary lymph nodes occurred in just 10 (8.3%) of the patients, and in all cases metastases were observed in 1–3 lymph nodes. All the patients un­derwent primary surgery. Radical mastectomies were performed on 98 (81.6%) patients, while the other 22 (18.4%) underwent breast-conserving surgery (BCS). Radiotherapy was performed in 36 patients (22 after BCS and 14 after mastectomy). Patients with nodal involvement (10 patients) received adjuvant chemotherapy, and 8 patients with hormone receptor expression received hormonotherapy with tamoxifen. The 10-year DFS rate was 90%. Out of 120 patients with T-MBC, only 4 (3.3%) died from this cancer. We showed that none of the population, neither clinical nor microscopic, had a statistically significant influence on the 10-year disease-free survival rate. Our results are similar to others presented in literature
