In an investigation of the role of peroxidase enzymes in the differentiation of the tissues of the crease region of barley, plants of winter barley cv. Halcyon were grown from anthesis onwards in controlled conditions at a constant temperature of 16 degrees C. Four ears were harvested at 2-d intervals from 6 d after anthesis (daa) until 50 daa. Grains from mid-ear were used for (i) fresh and dr...

Aim of the study New interferon-free direct-acting antiviral (DAA) therapy has led to major progress in hepatitis C virus (HCV) treatment. Current outcomes are promising, especially in compensated cirrhosis. However, there are reports of accelerated hepatocellular carcinoma (HCC) recurrence after surgery in patients treated with DAAs. The influence of DAA therapy on the timing and frequency of ...

At the 2016 Conference on Retroviruses and Opportunistic Infections (CROI) in Boston, Massachusetts, hepatitis C virus (HCV) infection remained a major theme in the context of HIV-associated liver disease, although other causes of liver disease garnered increased attention, including fatty liver disease, hepatitis B, and the impact of HIV disease itself on the liver. Although no data from phase...

Early research shows several advantages of the Direct Anterior Approach (DAA) in total hip arthroplasty (THA), although no studies evaluated the DAA on a regular operating table without using fluoroscopy. We performed a retrospective cohort study on the outcome of this variation of the DAA compared with the posterolateral approach (PLA) with one year follow-up. All procedures were uncemented TH...

BACKGROUND A genomic biomarker identifying patients likely to benefit from drotrecogin alfa (activated) (DAA) may be clinically useful as a companion diagnostic. This trial was designed to validate biomarkers (improved response polymorphisms (IRPs)). Each IRP (A and B) contains two single nucleotide polymorphisms that were associated with a differential DAA treatment effect. METHODS DAA is ty...

BACKGROUND The direct anterior approach (DAA) is increasingly popular for hip replacement. However, the small incision and the location near to the groin might increase the risk of periprosthetic joint infection (PJI). We asked the questions (i) whether there is an increased risk of infection for this approach, and (ii) whether the spectrum of microorganisms differs between patients with DAA an...

Background Cure rates for chronic hepatitis C have improved dramatically with direct-acting antivirals (DAAs), but treatment barriers remain. We aimed to compare treatment initiation rates and barriers across both interferon-based and DAA-based eras. Methods We conducted a retrospective cohort study of all patients with chronic hepatitis C seen at an academic hepatology clinic from 1999 to 20...

Background Direct-acting antivirals (DAA) as curative therapy for hepatitis C virus (HCV) infection offer >95% sustained virologic response (SVR), including in patients with human immunodeficiency virus (HIV) infection. Despite improved safety and efficacy of HCV treatment, challenges remain, including drug-drug interactions between DAA and antiretroviral therapy (ART) and restrictions on acces...

Studies were done to see the effects of five toxic baits based on metaldehyde and/or carbaryl on the taxonomic composition of soil meso and macrofauna, and determined the density of beneficial organisms in soybean under no tillage. Six treatments were tested and soil monoliths were taken before application and at 45 and 75 days after application (DAA). Before application, 1601 individuals were ...

Direct anonymous attestation (DAA) is a special digital signature primitive, which provides a balance between signer authentication and privacy. One of the most interesting properties that makes this primitive attractive in practice is its construction of signers. The signer role of DAA is split between two entities, a principal signer (a trusted platform module (TPM)) with limited computationa...
