(Verlag Dr. Friedrich Pfeil, 2013)Although the diversity of marine molluscs along the Humboldt Current ecosystem is relatively well known, some groups such as opisthobranch sea slugs and snails (Gastropoda, Heterobranchia) have received little attention. ... -
Effect of estradiol and prostaglandin application during post calving on reproductive performance in holstein cows under intensive farming
(Asociación Peruana de Reproducción Animal, 2021)After delivery, the process of uterine involution begins, in which a series of changes in the anatomy and histology of the uterus take place and there is a return to cyclical activity of the ovary. The objective was to ... -
Adult-onset rasmussen’s encephalitis: Response after steroid pulses
(Sociedade Portuguesa de Neurologia, 2020)Introduction: Rasmussen’s encephalitis (RE) is an infrequent chronic neurological disorder characterized by unihemispheric inflammation of the brain cortex, refractory epilepsy, and progressive motor and cognitive decline. ... -
Filosofía educativa dinámica para la gestión tecnológica de aprendizaje
(Universidad de Valladolid, 2023)Notions such as STEAM education, computational thinking, gamification, and the manipulation of ICT have appeared to configure what is known as Education 4.0. In the Latin American context and the economic, political, ... -
Factors predictive of high disease activity early in the course of SLE in patients from a Latin-American cohort
(W.B. Saunders, 2017)Aims To determine the factors predictive of disease activity early in the course of SLE (baseline visit). Methods Patients from GLADEL, a multi-national, multi-ethnic, Latin-American lupus cohort were included. Disease ... -
Radiographic correlation of skeletal maturation using the stages of dental calcification in a Peruvian population
(Hindawi, 2020)Objective. To identify the correlation between the Baccetti method of SM (skeletal maturation) and the stages of DC (dental calcification) using the Demirjian method in the Orthodontics Service of the Universidad Peruana ... -
Unexpected population fragmentation in an endangered seabird: the case of the Peruvian diving-petrel
(Nature Publishing Group, 2019)In less than one century, the once-abundant Peruvian diving petrel has become the first endangered seabird of the Humboldt Current System (HCS). This small endemic petrel of the South American Pacific coast is now an ... -
Genome-wide identification, expression profile and evolutionary relationships of TPS genes in the neotropical fruit tree species Psidium cattleyanum
(Nature Research, 2023)Terpenoids are essential for plant growth, development, defense, and adaptation mechanisms. Psidium cattleyanum (Myrtaceae) is a fleshy fruit tree species endemics from Atlantic Forest, known for its pleasant fragrance and ... -
Prevalence and incidence of stroke in Latin America and the Caribbean: a systematic review and meta-analysis
(Nature Research, 2023)Stroke is a recurrent and well-known cardiovascular event and a leading cause of death worldwide. We identified reliable epidemiological evidence of stroke in Latin America and the Caribbean (LAC) and estimated the prevalence ... -
Scientific validation of three-dimensional stereophotogrammetry compared to the IGAIS clinical scale for assessing wrinkles and scars after laser treatment
(Nature Research, 2021)Measuring outcomes from treatments to the skin is either reliant upon patient’s subjective feedback or scale-based peer assessments. Three-Dimensional stereophotogrammetry intend to accurately quantify skin microtopography ... -
Histological and contractile changes in the genioglossus muscle after nasal obstruction in growing rats
(Nature Research, 2023)The aim of the study was to address the genioglossus muscle physiological and histological changes after unilateral nasal obstruction in growing rats. Fifty-four 6-day-old male Wistar albino rats were randomly divided into ... -
Enhanced, coordinated conservation efforts required to avoid extinction of critically endangered Eastern Pacific leatherback turtles
(Nature Research, 2020)Failure to improve the conservation status of endangered species is often related to inadequate allocation of conservation resources to highest priority issues. Eastern Pacific (EP) leatherbacks are perhaps the most ... -
Soil carbon is a useful surrogate for conservation planning in developing nations
(Nature Publishing Group, 2019)Defining the optimal placement of areas for biodiversity conservation in developing nations remains a significant challenge. Our best methods for spatially targeting potential locations for biodiversity conservation rely ... -
Efficient Parallel Sorting for Migrating Birds Optimization When Solving Machine-Part Cell Formation Problems
(Hindawi, 2016)The Machine-Part Cell Formation Problem (MPCFP) is a NP-Hard optimization problem that consists in grouping machines and parts in a set of cells, so that each cell can operate independently and the intercell movements are ... -
A Matheuristic Approach Combining Local Search and Mathematical Programming
(Hindawi, 2016)A novel matheuristic approach is presented and tested on a well-known optimisation problem, namely, capacitated facility location problem (CFLP). The algorithm combines local search and mathematical programming. While the ... -
Flame curtain kilns produce biochar from dry biomass with minimal methane emissions
(Elsevier, 2023)Flame curtain kilns have emerged as the preferred biochar technology for smallholders but reported methane emissions (30 g kg−1 biochar) have impeded carbon certification. Here, for flame curtain kilns we show almost no ... -
A cone-beam computed tomography study of the root and root canal morphology of maxillary first premolars in young Peruvians
(Wolters Kluwer Medknow Publications, 2023)Introduction: Cone-beam computed tomography (CBCT) is an important diagnostic tool today as it allows the evaluation of the internal structures of hard tissues. This study investigated the internal root morphology of the ... -
