TL;DR: A history of transfusion with blood that was not screened for anti-HCV and length of time on hemodialysis were associated with HCV infection.
Abstract: A survey was conducted among the hemodialysis units of the city of Campo Grande, located in the state of Mato Grosso do Sul in the Mid-west region of Brazil, with the aim of investigating the prevalence, risk factors, and genotypes of hepatitis C virus (HCV) infection. A total of 163 patients were interviewed in five dialysis units. Serum samples were screened for anti-HCV. Positive samples were tested for HCV RNA and genotyped. The prevalence of anti-HCV was 11% (95% CI: 6.8-17.1). A history of transfusion with blood that was not screened for anti-HCV and length of time on hemodialysis were associated with HCV infection. HCV RNA was detected in 12 samples: ten were of genotype 1, subtypes 1a (75%) and 1b (8.3%), and two were of genotype 3, subtype 3a (16.7%).

TL;DR: In this article, a different methodology was used to isolate and purify oxoaporphine alkaloids, as they are difficult to separate by the usual workup when in mixture.
Abstract: A different methodology was used to isolate and purify oxoaporphine alkaloids, as they are difficult to separate by the usual workup when in mixture. Alkaloid extracts from Annonaceae species were obtained by base/acid extraction. The extracts were concentrated and submitted to partition in solutions of acids of different pKa values, followed by separation by preparative TLC using 1 mm thick silica gel impregnated with oxalic acid (11.2% w/w). Liriodenine, lisycamine, lanuginosine, and O-methylmoschatoline were obtained and tested against tumoral cells (line Hep2, ATCC-CCL 23, larynx carcinoma). Only O-methylmoschatoline (IC50 12.4 µM) was more active than cisplatin (18.0 µM).

TL;DR: In this paper, the first step is an outer-sphere electron transfer to the oxygen molecule and the second step involves adsorption of OH on the electrode surface, which explains why the former is a better catalyst than the latter.
