Abstract Among 164 fish from the upper São Francisco river, caught in the Três Marias reservoir (18º 12’ 59” S; 45º 17’ 34” W) or downstream from this reservoir (18º 12’ 32” S; 45º 15’ 41” W) in 200...

A total of 103 specimens of Hoplias intermedius (Günther, 1864) and 86 specimens of H. malabaricus (Bloch, 1794) from the upper São Francisco River, State of Minas Gerais were collected between April 2011 and August 20...

As duas pinturas de Rembrandt van Rijn (1606-1669) nas quais o artista holandês retrata lições de anatomia em 1632 e 1656 revelam limitações que a leitura de uma obra de arte pode impor ao olhar contemporâneo se no...

Understanding structure at the atomic scale is fundamental for understanding the functioning and the development of materials with improved properties. Compared with other probes providing atomic resolution, electrons of...

Abstract Background Myocardial sleeves of the caudal vena cava are the predilection site for atrial tachycardia (AT) in horses. Caudal vena cava isolation guided by the ablation index, a lesion quality marker incorporati...

In public healthcare systems, effectiveness is a central requirement for determining which services should be offered and reimbursed. Yet, due to its technical nature and to the need for specification through specialised...

Abstract Background Reliable ECGs are crucial for diagnosing arrhythmias, yet a lack of standardization impedes arrhythmia diagnosis and treatment in horses. Objectives To objectively determine an optimal position of Ein...

Abstract Background Heart disease is an important cause of morbidity and mortality in cats, but there is limited evidence of the benefit of any medication. Hypothesis The angiotensin‐converting enzyme inhibitor benazep...

Lassa fever is a zoonotic disease endemic to several West African countries, with seasonal outbreaks and potential to cause future epidemics. Vaccines and other medical countermeasures are in development, requiring relia...

Differential scanning fluorimetry (DSF) using the inherent fluorescence of proteins (nDSF) is a popular technique to evaluate thermal protein stability in different conditions (e.g. buffer, pH). In many cases, ligand bin...

Sensing the scattered fields of single metallic nanostructures is a crucial step towards the applications of isolated plasmonic antennas, such as for the sensing of single molecules or nanoparticles. In the past, both ne...

Abstract Background Cardiac catheterizations in horses are mainly performed in the right heart, as access to the left heart traditionally requires an arterial approach. Transseptal puncture (TSP) has been adapted for hor...

The ability of phytochromes (Phy) to act as photointerconvertible light switches in plants and microorganisms depends on key interactions between the bilin chromophore and the apoprotein that promote bilin attachment and...

Abstract Background The care of sick neonatal foals is labor‐intensive and costly. Prediction of risk of death upon admission is often difficult but might support decision‐making. Objectives To determine diseases and...

Abstract To interpret and transmit biological signals, proteins use correlated motions. Experimental determination of these dynamics and the structural distributions they generate remains a key challenge. Here, using 114...
