This work documents the first record of Anthias noeli Anderson & Baldwin, 2000 in Peru. Between 2016 and 2019, fifteen specimens were captured from the littoral of the Tumbes Department, located in the northernmost of Peru. Fresh photographs were taken of the specimens and meristic and morphometric analyses were conducted for species identification. Additionally, muscle tissue was extracted from five individuals to determine COI gene sequences. Phylogenetic analyses confirmed the specimens' identity as A. noeli, and the sequences were deposited in the public database BOLD Systems, representing the first deposited sequences for this species. This record expands the southern distribution of A. noeli.

This article presents a review about the cosmological constant, the Friedmann-Lemaitre-Roberson-Walker cosmological model and its relationship with Einstein's gravitational theory and with Friedmann's equations. The observational evidence is evaluated and the experimental results of the accelerated expansion of the Universe are analyzed. Finally, the physical nature of the cosmological constant is described as a possibility of dark energy.

Debido a su gran biocompatibilidad, la hidroxiapatita (HAp) es ampliamente usada como recubrimiento de implantes quirúrgicos, ortopédicos y dentales con el fin de mejorar la biocompatibilidad y osteointegración de los implantes. Sin embargo, dada su complejidad estructural, las técnicas convencionales de recubrimiento no proporcionan buena uniformidad, adhesión al sustrato y control de la estequiometría, por lo que la su pureza estructural resulta ser baja. Una de las técnicas que permite obtener recubrimientos de alta cristalinidad y uniformidad es la pulverización catódica de magnetrones con caras opuestas (magnetron facing target sputtering, MFTS), o también conocida como pulverización catódica de magnetrones en ángulo recto (right angle magnetron sputtering, RAMS). En este artículo se describe las condiciones necesarias para la implementación de dicho sistema con el ob...

Recent evidence suggests that late reperfusion of an occluded infarct-related artery (IRA) after acute myocardial acute infarction (MAI), may reduce the frecuency of subsequent arrhythmic events and sudden death. Mechanical reperfusion of an occluded IRA, performing percutaneous trasluminal coronary angioplasty (PTCA) 48 to 2 weeks after MAI, has a big success rate, and low symptomatic restenosis. Twenty subjects (19 men and 1 women, aged 32 to 77 year) with a first MAI, signal-averaged electrocardiographic (SAECG), and an occluded IRA were prospectively identified. Late potentials were present in 14 patients after MAI. Eighteenth had a successful PTCA of the occluded IRA, 6 to 32 days after MAI. Follow-up SAECG was performed 1 to 8 days later. In the subgroup of 12 patients with successful reperfusion with an abnormal SAECG before PTCS, 7 (58,3%) showed resolution of late potentials at ...

The aim of the present research was to determine the prevalence of Trypanosoma vivax in cattle of the province of Chachapoyas, located in the tropics of Perú. A total of 270 blood smears from 270 criollos, Holstein, Brown Swiss and Zebu crosses were evaluated. The prevalence of T. viva.x was 1 O.O± 3 .4% (27 /270) without differences between sexes (P>0.05). None of the positive animals showed clinical signs related to trypanosomosis. The study reported for the first time the presence of T. viva.x in the (Chachapoyas province. Further studies in this and other tropical regions using more sensitive techniques are recommended.

A study was carried out to determine the effects of dietary electrolyte balance (BED) on the productive performance, carcass characteristics and blood metabolites of guinea pig in an experimental farm in Cajamarca, Peru. In total, 150 male guinea pigs distributed in five treatments with five levels of BED: 100, 200, 300, 400 and 500 mEq/kg. Each treatment had six repetitions and each repetition with five guinea pigs/pen. The guinea pigs consumed concentrated feed for 42 days. At the end of the experimental period, six guinea pigs per treatment were slaughtered to determine the carcass yield, relative weights of the viscera and concentration of blood metabolites. Differences (p<0.05) were found in final body weight, body weight gain, and feed conversion index in favour of guinea pigs with BED of 300 mEq/kg. There were no significant differences between treatments in carcass characteris...
