Cytotoxicity and genotoxicity of cadmium oxide nanoparticles evaluated using in vitro assays
In this study, 10 nm CdO core-PEG stabilized NPs were synthesized, characterized and used for evaluation of CdO NPs’ cytotoxicity and genotoxicity. Release of cadmium ions (Cd+2) from the CdO NPs in cell culture medium, cellular uptake of the NPs, and the endotoxin content of the particles were measured prior to the toxicity assays. Cytotoxicity was evaluated using the MTS assay, ATP content detection assay, and LDH assay. Genotoxicity was assessed using the Ames test, Comet assay, micronucleus assay, and mouse lymphoma assay. The cytotoxicity of cadmium chloride (CdCl2) was also evaluated along with that of the CdO NPs. The results showed that endotoxin levels within the CdO NPs were below the limit of detection. CdO NPs induced concentration-dependent cytotoxicity in TK6 and HepG2 cells with the MTS, ATP and LDH assays. Although the genotoxicity of CdO NPs was negative in the Ames test, positive results were obtained with the micronucleus, Comet, and mouse lymphoma assays. The negative response of CdO NPs with the Ames test may be the result of unsuitability of the assay for measuring NPs, while the positive responses from other genotoxicity assays suggest that CdO NPs can induce chromosomal damage, single or double strand breaks in DNA, and mutations. The toxicity of the CdO NPs results from the NPs themselves and not from the released Cd+2, because the ions released from the NPs were minimal. These results demonstrate that CdO NPs are cytotoxic and genotoxic ...

We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN. PMID: 33028760 [PubMed - in process]
Authors: Cáceres-Perkins W, Cabanillas F, San Vicente G, Rivera-Franceschini C, Sobrino-Najul E, Vega-Vázquez LI, Conde-Sterling D Abstract Mucosa-associated lymphoid tissue (MALT) lymphomas are B-cell neoplasms that commonly affect the gastrointestinal (GI) tract, usually the stomach. In most cases, extranodal marginal zone lymphoma (ENMZL) is an indolent disease. Bone marrow involvement is common with MALT lymphoma accompanied by paraproteinemia; such involvement impels disease progression. Here, we present the case of an 82-year-old Hispanic patient with long-standing ENMZL in whom the gastric site...
CONCLUSION: Our data suggest that these two polymorphisms do not contribute to AD in the population from the Mersin region of the Eastern Mediterranean. Further studies with larger sample sizes must be conducted to ascertain the association between the 2 polymorphisms. PMID: 33031695 [PubMed - as supplied by publisher]
Conclusion: Pola + BR is cost-effective versus BR for the treatment of transplant-ineligible relapsed/refractory diffuse large B-cell lymphoma in the US. PMID: 33028076 [PubMed - as supplied by publisher]
