BACKGROUND Substantial evidence suggests that increased oxidative stress in hemodialysis (HD) patients may contribute to cardiovascular complications. Oxidative modifications of human serum albumin (HSA), the largest thiol pool in plasma, alter its biological properties and may affect its antioxidant potential in HD patients. METHODS We conducted a long-term follow-up study in a cohort of nor...

This study determined whether clinical salt-sensitive hypertension (cSSHT) results from the interaction between partial arterial baroreceptor impairment and a high-sodium (HNa) diet. In three series (S-I, S-II, S-III), mean arterial pressure (MAP) of conscious male Wistar ChR003 rats was measured once before (pdMAP) and twice after either sham (SHM) or bilateral aortic denervation (AD), followi...

Este artigo analisa a história de Anália: mulher, negra, pobre, favelada, diversas internações no Hospício Nacional Alienados (HNA) e condenada 15 anos prisão, após cometer um assassinato em 1937. Em sua vida, Anália esteve conflito com diferentes discursos hegemônicos, como as normais culturais gênero época. uma das HNA, “uma mulher cor preta” foi o nome registrado seu prontuário, que identifi...

The cytochrome P450 (CYP) isoforms that catalyze the oxidation metabolism of 6-methoxy-2-napthylacetic acid (6-MNA), an active metabolite of nabumetone, were studied in rats and humans. Using an extractive reversed-phase HPLC assay with fluorescence detection, monophasic Michaelis-Menten kinetics was obtained for the formation of 6-hydroxy-2-naphthylacetic acid (6-HNA) in liver microsomes of ra...

Two novel inorganic–organic hybrid supramolecular assemblies, namely, (4-HNA)(18-crown-6)(HSO4) (1) and (4-HNA)2(18-crown-6)2(PF6)2(CH3OH) (2) (4-HNA = 4-nitroanilinium), were synthesized and characterized by infrared spectroscopy, single X-ray diffraction, differential scanning calorimetry (DSC), and temperature-dependent dielectric measurements. The two compounds underwent reversible phase tr...

Antisense oligonucleotide (AO) mediated exon skipping has been widely explored as a therapeutic strategy for several diseases, in particular, for rare genetic disorders such as Duchenne muscular dystrophy (DMD). To date, the potential of anhydrohexitol nucleic acid (HNA), cyclohexenyl nucleic acid (CeNA) and altritol nucleic acid (ANA) has not been explored in exon skipping. For the first time,...

Alloimmunization to granulocyte-specific antigens can occur during pregnancy. Maternal antibodies of IgG class can cross the placenta to result in alloimmune neonatal neutropenia. Antibodies to human neutrophil antigens anti-HNA-1a, HNA-1b, and HNA-2a have been most commonly reported to cause alloimmune neonatal neutropenia. Isoantibodies to Fc gamma RIIIb (CD16) if mother is a HNA-null phenoty...

Flow cytometry was applied to assess the microbiological impact of treated sewage effluent discharge into a small brook carrying surface runoff water. Increases in dissolved organic carbon and soluble reactive phosphorous were accompanied by increases in counts of intact bacteria by up to eightfold. Effluent ingress furthermore resulted in a pronounced shift of bacterial clusters. Whereas brook...

Septin 9 (SEPT9) interacts with microtubules (MTs) and is mutated in hereditary neuralgic amyotrophy (HNA), an autosomal-dominant neuropathy. The mechanism of SEPT9 interaction with MTs and the molecular basis of HNA are unknown. Here, we show that the N-terminal domain of SEPT9 contains the novel repeat motifs K/R-x-x-E/D and R/K-R-x-E, which bind and bundle MTs by interacting with the acidic ...

• TRALI may be induced by antibodies to HLA or HNA antigens or lipids, which accumulate during storage. • Prestorage experimental filtration of RBCs removes HLA and HNA antibodies, decreases lipid priming activity, and mitigates TRALI in an animal model. Transfusion-related acute lung injury (TRALI) remains a significant cause of transfusionrelated mortality with red cell transfusion. We hypoth...
