Understanding pre‐eclampsia and fetal growth restriction at high altitude: A narrative review

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Pre‐eclampsia (PE) and fetal growth restriction (FGR) are among the leading causes of maternal and perinatal morbidity and mortality worldwide. Both conditions are more frequent and severe at high altitudes due to physiological changes in oxygen availability and vascular adaptation.

Joint Estimation and Bandwidth Selection in Partially Parametric Models

open access: yesJournal of Applied Econometrics, EarlyView.
ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Interrater reliability in pediatric high‐resolution anorectal manometry recordings

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives High‐resolution anorectal manometry (HR‐ARM) is a diagnostic test assessing anorectal neuromuscular function in children with constipation and/or fecal incontinence. Interrater reliability of HR‐ARM in children has not been previously studied. The aim of this study was to assess the interrater reliability of pediatric HR‐ARM studies.

Mid-term coral-algal dynamics and conservation status of a Gorgona Island (Tropical Eastern Pacific) coral reef

open access: yesRevista de Biología Tropical, 2010
Colombian coral reefs, as other reefs worldwide, have deteriorated significantly during the last few decades due to both natural and anthropogenic disturbances. The National Monitoring System for Coral Reefs in Colombia (SIMAC) was established in 1998 to

The Automated Vestibular Rehabilitation System: Normative Data From a Machine Vision‐Guided Platform

open access: yesThe Laryngoscope, EarlyView.
The Automated Vestibular Rehabilitation System (AVRS) is a machine vision‐based tool designed to increase accessibility to vestibular rehabilitation therapy by automating exercise delivery and tracking head‐eye movements in real time. In n = 40 healthy adults, the AVRS accurately measured vestibulo‐ocular reflex (VOR) gain values near physiologic norms

Comparing non‐staining methods with Mutvei's solution to visualize growth increments in short‐lived intertidal marine gastropod shells

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Mutvei's solution is a widely utilized standard staining method for revealing growth increments in biogenic carbonates; however, it is a slightly toxic, destructive approach with varying success across species groups. Therefore, there has been growing interest in finding non‐toxic, less destructive, and straightforward alternative techniques ...
