Stimulation of antioxidant machinery in rats by low dose ionizing radiation: a concept of radiation hormesis.
CONCLUSION: Low doses of X-rays exposure may afford radiation hormesis by providing protection to organs from oxidative injury and support immune reaction. PMID: 30843009 [PubMed - as supplied by publisher]
ConclusionsMultiscale approach ’s predictive capabilities are based on the fundamental scientific knowledge. Their strength is in relation to actual physical, chemical, and biological processes that take place following the ions incidence on tissue. This makes the approach flexible and versatile to include various conditions, s uch as the degree of aeration or the presence of sensitizing nanoparticles, related to particular cases. The ideas for how the MSA can contribute to an improved optimization of therapy planning are summarized in the review.
In this study, a BMI ≥ 30 kg/m2 resulted in higher MAT failure rates. Nonobese patients had better knee functional results compared with obese individuals.

ConclusionsIn this qualitative metasynthesis, reasons patients visit the ED over primary care included (1) urgency of the medical condition, (2) barriers to accessing primary care, (3) advantages of the ED, and (4) fulfillment of medical needs and quality of care in the ED.

Walker, Natalia Tretyakova, Richard J. AlbertiniAbstractEpidemiological studies of 1,3-butadiene (BD) exposures have reported a possible association with chronic myelogenous leukemia (CML), which is defined by the presence of the t(9;22) translocation (Philadelphia chromosome) creating an oncogenic BCR-ABL fusion gene. Butadiene diepoxide (DEB), the most mutagenic of three epoxides resulting from BD, forms DNA-DNA crosslink adducts that can lead ...
This study reported a case of an 80-year-old man with a left total knee arthroplasty (TKA) performed eight years before his presentation. He presented with left knee swelling and pain for one month. Knee X-rays showed a normal joint space with no loosening of his prosthesis. His chest X-ray showed miliary disease, and microbiological studies of his sputum and synovial fluid aspirate grew Mycobacteria tuberculosis complex.
Conclusions: In this real-life cohort of patients with axSpA, although males more often had structural damage on X-rays, females had similar disease with regard to SpA features and at least equal disease activity parameters compared to males. PMID: 31418321 [PubMed - as supplied by publisher]
The idea to split soft X-ray and hard X-ray beams on the same axis into different directions is presented. A thin-film beam splitter can serve this purpose. Performances of thin-film beam splitters made of carbon and aluminium were examined. The idea of thin-film beam splitters expands possibilities in the design of two-colour beamlines.
Abstract Epidemiological studies of 1,3-butadiene (BD) exposures have reported a possible association with chronic myelogenous leukemia (CML), which is defined by the presence of the t(9;22) translocation (Philadelphia chromosome) creating an oncogenic BCR-ABL fusion gene. Butadiene diepoxide (DEB), the most mutagenic of three epoxides resulting from BD, forms DNA-DNA crosslink adducts that can lead to DNA double-strand breaks (DSBs). Thus, a study was designed to determine if (±)-DEB exposure of HL60 cells, a promyelocytic leukemia cell line lacking the Philadelphia chromosome, can produce t(9;22) transl...
CONCLUSIONS: Our proposed approach achieves significant performance improvements compared with the existing methods based on the original CNN or pure variational models. PMID: 31403960 [PubMed - as supplied by publisher]
Conclusions: As a result, panoramic radiographs taken during dental diagnosis and treatment cause cytotoxicity and DNA damage in oral mucosal cells. Panoramic radiographs should be applied only when necessary, using an accurate radiographic technique and radioprotection criteria.
