COVID-19 among Chronic Dialysis Patients after First Year of Pandemic, Argentina.

We performed a descriptive study to characterize effects from COVID-19 among chronic dialysis patients compared with the general population in Argentina during March 2020-February 2021. COVID-19 case-fatality rate of chronic dialysis patients was 10 times the national rate; the age-standardized mortality ratio was 6.8 (95% CI 6.

Molecular detection of circulating tyrosinase mRNA: optimization in a preclinical xenograft mouse melanoma model and further evaluation in samples from advanced melanoma patients.

We designed high-affinity primers for the mRNA sequence of human tyrosinase to test the value of molecular detection of circulating melanoma cells by reverse transcription-polymerase chain reaction (RT-PCR). The optimization process included in vitro settings and in vivo studies in a xenograft mouse model. We detected tyrosinase expression with at least 40 pg and 1.
