Prognostic impact of Ki‐67 proliferative index in resectable pancreatic ductal adenocarcinoma

open access: yesBJS Open, Volume 3, Issue 5, Page 646-655, October 2019., 2019
The aim of this retrospective cohort study was to analyse the role of Ki‐67 as a prognostic factor in a cohort of patients with resected pancreatic ductal adenocarcinoma. Ki‐67 index was identified as an independent predictor of poor disease‐specific and disease‐free survival.

Application of artificial intelligence to ultrasound imaging for benign gynecological disorders: systematic review

open access: yesUltrasound in Obstetrics &Gynecology, Volume 65, Issue 3, Page 295-302, March 2025.
ABSTRACT Objective Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders ...

Range‐wide intraspecific variation reflects past adaptation to climate in a gypsophile Mediterranean shrub

open access: yesJournal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.
Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.

Plant‐based meat analogues marketed in Catalonia: evaluation of the nutritional profile

open access: yesFood Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract In later years, a growing trend is apparent of vegetarian or vegan diets attributable to a number of causes, among of others, consumers’ concern for animal welfare, climate change and, to a lesser degree, for health‐related issues. On a par to this growth, availability of meat analogues in the market has also been on the rise. In this context,

Plant‐based meat analogues marketed in Catalonia: analysis of contaminants, essential elements, microbiological and physicochemical status, dietary intake estimation and health risk assessment

open access: yesFood Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract The latest barometer of food safety in Catalonia conducted by the Catalan Food Safety Agency (ACSA for its initials in Catalan) in 2021 shows that 28.7% of the population consumes meat analogues (substitutes). The main reasons for consuming this type of food are animal welfare, followed by environmental and health reasons.

Performance of machine‐learning approach for prediction of pre‐eclampsia in a middle‐income country

open access: yesUltrasound in Obstetrics &Gynecology, Volume 63, Issue 3, Page 350-357, March 2024.
ABSTRACT Objective Pre‐eclampsia (PE) is a serious complication of pregnancy associated with maternal and fetal morbidity and mortality. As current prediction models have limitations and may not be applicable in resource‐limited settings, we aimed to develop a machine‐learning (ML) algorithm that offers a potential solution for developing accurate and ...

Divergent selection in a Mediterranean pine on local spatial scales

open access: yesJournal of Ecology, Volume 112, Issue 2, Page 278-290, February 2024.
This study highlights how divergent selection in heterogeneous microenvironments shapes and maintains the functional genetic variation within populations of long‐lived forest tree species, being the first to focus on adaptive genetic divergence between south‐ and north‐facing slopes within continuous forest stands.

Variables del microhábitat que influyen en la grulla cubana (Grus canadensis nesiotes) para seleccionar el sitio de anidación en un humedal de Cuba

open access: yesHuitzil, 2017
La grulla cubana (Grus canadensis nesiotes), subespecie endémica de Cuba, está amenazada; se estiman tan sólo 550 individuos. La facilitación de zonas de nidificación quizá incrementaría el éxito reproductivo de la subespecie.

Demografía genética en Cachi - Valle Calchaquí (Salta) / Genetic demography in Cachi – Calchaquí Valley (Salta)

open access: yesRevista Argentina de Antropología Biológica, 2015
A partir de parámetros demográficos se estimaron los efectos de deriva génica, flujo génico y selección natural a través de los Coeficientes de Aislamiento Reproductivo y de Endogamia, Tasa de Migración Efectiva e Índice de Oportunidad para la Selección.
