Unlocking rivers' hidden diversity and ecological status using DNA metabarcoding in Northwest Spain.

Rivers are crucial ecosystems supporting biodiversity and human well-being, yet they face increasing degradation globally. Traditional river biomonitoring methods based on morphological identification of macroinvertebrates present challenges in terms of taxonomic resolution and scalability. This study explores the application of DNA metabarcoding analysis in both bulk and environmental DNA (eDNA) samples for comprehensive assessment of macrozoobenthic biodiversity, detection of invasive and endangered species, and evaluation of river ecological status in northwestern Spain.

Lyko, 2017: A new threat to Iberian inland waters.

An eco-monitoring programme to assess faunal biodiversity in the main rivers of the northern Iberian Peninsula (Spain) reveals the first occurrence of the marbled crayfish (Decapoda: Cambaridae) in Iberian inland waters. Iberian specimens have been identified by combining morphological and genetic traits. We discuss the most plausible pathways and introduction vectors, its potential invasiveness and subsequent impacts on host localities.

Steady-state solutions for the Muskat problem.

In this paper we study the existence of stationary solutions for the Muskat problem with a large surface tension coefficient. Ehrnstrom, Escher and Matioc studied in Mats Ehrnström (Methods Appl Anal 20:33-46, 2013) that there exists solutions to this problem for surface tensions below a finite value. In these notes we go beyond this value considering large surface tension.

Risk Factors and Laboratory Findings Associated With Diabetic Ketoacidosis in Hospitalized Pediatric Patients.

Background: Diabetic ketoacidosis (DKA), the most serious and acute complication of type 1 diabetes, has an incidence of 6%-8% among known pediatric type 1 diabetes patients, although risk factors associated with severe DKA in the pediatric population are poorly understood [1].

Method: A single-institution, retrospective chart analysis of pediatric DKA patients admitted to our pediatric intensive care unit (PICU) was conducted in South Alabama between October 2017 and April 2021. Laboratory findings were obtained from venous samples collected from the patients on admission.

The feasibility and acceptability of a pilot randomized controlled trial testing pharmacy-based HPV vaccine completion.

Objective: Immunizing pharmacists can administer vaccines; however, they are less likely to administer adolescent vaccines such as vaccines that protect against human papillomavirus (HPV). Although past research has recommended incorporating pharmacists to increase adolescent vaccination, few intervention studies have tested healthcare delivery models that incorporate pharmacists to aid in vaccine series completion. This research explored the feasibility and acceptability of an intervention in which pharmacists administered booster doses of the HPV vaccine series.

Cubic Nanoparticles for Magnetic Hyperthermia: Process Optimization and Potential Industrial Implementation.

Cubic nanoparticles are referred to as the best shaped particles for magnetic hyperthermia applications. In this work, the best set of values for obtaining optimized shape and size of magnetic particles (namely: reagents quantities and proportions, type of solvents, temperature, etc.) is determined.

All That Glitters Is Not Gold: The Other Insects That Fall into the Asian Yellow-Legged Hornet 'Specific' Traps.

The introduction of invasive species is considered one of the major threats to the biodiversity conservation worldwide. In recent years, an Asian invasive species of wasp has set off alarms in Europe and elsewhere in the world, . The Asian wasp was accidentally introduced in France around 2004 and shortly thereafter it was able to colonise practically all of Europe, including the Iberian Peninsula.

Guillain-Barré syndrome with unilateral peripheral facial and bulbar palsy in a child: A case report.

Guillain-Barré syndrome is characterized by progressive motor weakness, sensory changes, dysautonomia, and areflexia. Cranial nerve palsies are frequent in Guillain-Barré syndrome. Among cranial nerve palsies in Guillain-Barré syndrome, facial nerve palsy is the most common affecting around half of the cases.

Effect of dissolved oxygen concentration on nitrite accumulation in nitrifying sequencing batch reactor.

A mathematical model based on Activated Sludge Model No. 3 (International Water Association, London) and laboratory-scale experiments were used to investigate ammonia conversion by nitrification in a sequencing batch reactor (SBR). The purpose of the study was to assess the effect of dissolved oxygen concentration on nitrite accumulation in the SBR.

The effect of sodium chloride on the two-step kinetics of the nitrifying process.

Sodium chloride affects the transformation rate of several compounds in bioreactors. Most authors report a decrease in microorganism activity at increasing salt concentrations. In this work, a kinetic model that relates sodium chloride concentration with the rates of each step of the nitrification process is proposed; thus, the effect of sodium chloride concentration (0 to 60 g/L) on the nitritation and nitratation rates was separately studied.
