Nutrition education for Cambodian refugees : evaluating a health intervention media project.

The purpose of this study was to test the video education tool, Choosing Cambodian Foods Wisely, to determine if Cambodian refugees would respond to this intervention as culturally appropriate and nutritionally educational. An evaluation study consisting of a pretest, posttest 1 and posttest 2 was introduced to a cluster sample of 20 Cambodian refugees; however, due to attrition, the analysis of the data was based on 17 cases. An ANOVA test revealed a significant difference between the means of the test scores. These results supported the hypothesis that the video education tool was effective in increasing the knowledge, attitudes, and behaviors of the subjects in regard to the nutritional elements iron, calcium, cholesterol, sugar, and salt. The research further suggested that these increases were sustained over a one month period. Ninety percent of the subjects reported that the video provided at least some culturally appropriate, accurate, and useful nutrition information and that they would recommend the video to others. These study results suggest that health educators focus their attention on media methods to achieve health interventions for cultural groups

Insulinoma Presenting as an Unusual Cause of Marital Discord

Months before this patient’s near collapse, the metabolic derangements caused by his cancer manifested in his marriage. This case demonstrates the need to consider insulinoma in healthy appearing patients who experience behavioral disturbances that otherwise might be treated only with counseling

Auditory pathways: are 'what' and 'where' appropriate?

New evidence confirms that the auditory system encompasses temporal, parietal and frontal brain regions, some of which partly overlap with the visual system. But common assumptions about the functional homologies between sensory systems may be misleading

On quantum chosen-ciphertext attacks and learning with errors

Quantum computing is a significant threat to classical public-key cryptography. In strong “quantum access” security models, numerous symmetric-key cryptosystems are also vulnerable. We consider classical encryption in a model which grants the adversary quantum oracle access to encryption and decryption, but where the latter is restricted to non-adaptive (i.e., pre-challenge) queries only. We define this model formally using appropriate notions of ciphertext indistinguishability and semantic security (which are equivalent by standard arguments) and call it QCCA1 in analogy to the classical CCA1 security model. Using a bound on quantum random-access codes, we show that the standard PRF-based encryption schemes are QCCA1-secure when instantiated with quantum-secure primitives. We then revisit standard IND-CPA-secure Learning with Errors (LWE) encryption and show that leaking just one quantum decryption query (and no other queries or leakage of any kind) allows the adversary to recover the full secret key with constant success probability. In the classical setting, by contrast, recovering the key requires a linear number of decryption queries. The algorithm at the core of our attack is a (large-modulus version of) the well-known Bernstein-Vazirani algorithm. We emphasize that our results should not be interpreted as a weakness of these cryptosystems in their stated security setting (i.e., post-quantum chosen-plaintext secrecy). Rather, our results mean that, if these cryptosystems are exposed to chosen-ciphertext attacks (e.g., as a result of deployment in an inappropriate real-world setting) then quantum attacks are even more devastating than classical ones

New Techniques for Static Symmetry Breaking in Many-Sorted Finite Model Finding

© 2023 IEEE. J. Poremba, N. A. Day and A. Vakili, "New Techniques for Static Symmetry Breaking in Many-Sorted Finite Model Finding," in IEEE Transactions on Software Engineering, vol. 49, no. 6, pp. 3487-3503, 1 June 2023, doi: 10.1109/TSE.2023.3256939.Symmetry in finite model finding problems of many-sorted first-order logic (MSFOL) can be exploited to reduce the number of interpretations considered during search, thereby improving solver performance for tools such as the Alloy Analyzer. We present a framework to soundly compose static symmetry breaking schemes for MSFOL: 1) one for functions with distinct sorts in the domain and range; 2) one for functions where the range sort appears in the domain; and 3) one for predicates. We provide a novel presentation of sort inference in the context of symmetry breaking that yields a new mathematical link between sorts and symmetries. We empirically investigate how our symmetry breaking approaches affect solving performance.This work was supported in part by the Natural Sciences and Engineering Research Council of Canada (NSERC)

High STEAP1 expression is associated with improved outcome of Ewing's sarcoma patients

Background Ewing's sarcoma (ES) is the second most common bone or soft-tissue sarcoma in childhood and adolescence and features a high propensity to metastasize. The six-transmembrane epithelial antigen of the prostate 1 (STEAP1) is a membrane-bound mesenchymal stem cell marker highly expressed in ES. Here, we investigated the role of STEAP1 as an immunohistological marker for outcome prediction in patients with ES. Patients and methods Membranous STEAP1 immunoreactivity was analyzed using immunohistochemistry in 114 primary pre-chemotherapy ES of patients diagnosed from 1983 to 2010 and compared with clinical parameters and patient outcome. Median follow-up was 3.85 years (range 0.43-17.51). Results A total of 62.3% of the ES samples displayed detectable STEAP1 expression with predominant localization of the protein at the plasma membrane. High membranous STEAP1 immunoreactivity was found in 53.5%, which correlated with better overall survival (P=0.021). Accordingly, no or low membranous STEAP1 expression was identified as an independent risk factor in multivariate analysis (hazard ratio 2.65, P=0.036). Conclusion High membranous STEAP1 expression predicts improved outcome and may help to define a specific subgroup of ES patients, who might benefit from adapted therapy regimen
