To assess the impact and feasibility of a telehealth program using continuous glucose monitoring (CGM) and a connected insulin pen cap (CIPC) in nursing homes for older adults with insulin-treated diabetes. This multicenter, prospective, sequential, single-arm study consisted of three phases: (1) baseline, blind CGM (); (2) intervention 1, CGM () without alarms; and (3) intervention 2, CGM with alarms for hypo and hyperglycemia. Two telehealth visits from reference diabetes units were conducted to adjust antidiabetic treatments.

This process not only holds appeal in terms of improving plastic waste concerns but also contributes to the reduction of greenhouse gas emissions, thus aligning with the principles of a circular economy paradigm. In this study, the char produced from the pyrolysis of post-consumer mixed plastic waste has been activated with NaCO, KOH, NaOH, and KCO to improve the textural, structural, and composition characteristics, leading to improved adsorption capability.

Firstly, the effect of temperature and contact time on sugar recovery during pretreatment (in insoluble solid and liquid fraction) was studied in detail. Then, enzymatic hydrolysis using commercial cellulase was performed with the insoluble solid resulting from pretreatment.

The main objective of this study is to demonstrate the existence of microplastic pollution on three beaches on the coast of Granada (Spain), namely La Herradura, Motril Beach and La Rábita, characterizing the particles and the relationships in their distribution. This may contribute supporting the studies carried out at a national level in accordance with the Directive on Marine Strategy (2008/56/EC).

In both tests/tasks the animals are submitted to stressful situations, known to induce several responses that have been considered as parallels of some symptoms of the human depressive disorder. However, there is a lack of experimental evidence supporting associations between the behavioral responses displayed in both behavioral procedures by outbred rats.

In this work, an investigation of the adsorption of Cd, Co, Cr, Cu, Ni, Pb and Zn by five different types of microplastics was performed in Milli-Q water and natural waters (seawater, urban wastewater and irrigation water) via a series of batch adsorption experiments. The effects of concentration of metals and physicochemical characteristics of polymers were particularly studied.

A source of microplastics pollution is derived from personal care products that contain polyethylene micro-spheres which are not captured by wastewater plants. In this work, ten personal care products (mainly scrubs) containing microplastics and marketed in Spain, were physico-chemically characterized.

We develop theory, based on earlier work, to partition heritability into a component due to a combination of parent of origin, maternal, paternal and shared environment, and another component that estimates classical additive genetic variance. We use this theory to investigate the effects on heritability of the parental origin of alleles in 798 outbred heterogeneous stock rats across 199 complex traits.

It is postulated that STEP opposes the development of long-term potentiation (LTP) and that it exerts a restraint on long-term memory (LTM). Here, we examined whether STEP levels are regulated during hippocampal LTP and after training in hippocampal-dependent tasks.

Firstly, isolation of constituents of the olive cake was carried out. Then, experiments were performed by thermogravimetric analysis (TGA) and differential thermogravimetry (DTG) under inert and oxidative atmosphere at a heating rate of 15 K/min for each isolated fraction.

Experiments were carried out in nitrogen atmosphere at three heating rates (5, 10 and 20°C/min). The results of thermogravimetric tests carried out proved that the presence of lead did not change the main degradation pathways of selected biomass (almond shell (AS) and olive pomace (OP)).

They have recently been re-derived through embryo transfer (ET) to Sprague-Dawley females to generate specific pathogen free (SPF) RHA-I/RLA-I rats. Offspring were phenotyped at generations 1 (G1, born from Sprague-Dawley females), 3 and 5 (G3 and G5, born from RHA-I and RLA-I from G2-G4, respectively), and compared with generation 60 from our non-SPF colony.

The Roman high- (RHA-I) and the Roman low- (RLA-I) avoidance rat strains present well-differentiated behavioral profiles, with the RHA-I strain emerging as a putative genetic rat model of schizophrenia-related features. The RHA-I strain shows increased 5-HT and decreased mGlu2 receptor binding levels in prefrontal cortex (PFC).

Objectives: We have carried out a pharmacological characterization of the Roman high- (RHA-I) and low-avoidance (RLA-I) rat strains with different acutely administered propsychotic (DOI, MK-801) and antipsychotic drugs (haloperidol, clozapine), as well as apomorphine, on prepulse inhibition (PPI) of startle and locomotor activity (activity cages).
Results: RHA-I rats display a consistent deficit of PPI compared with RLA-I rats.
The hippocampus and amygdala have been proposed as key neural structures related to anxiety. A more active hippocampus/amygdala system has been related to greater anxious responses in situations involving conflict/novelty. The Roman Low- (RLA) and High-avoidance (RHA) rat lines/strains constitute a genetic model of differential anxiety.

The Roman high- (RHA-I) and low-avoidance (RLA-I) inbred rats have been psychogenetically selected for their rapid versus extremely poor acquisition of the two-way avoidance task in the shuttle box and present two well-differentiated profiles regarding several traits related to anxiety, impulsivity and sensitivity to (dopaminergic) psychostimulants. In this study we have tested animals from both strains in two behavioral paradigms that are related to schizophrenia, i.

NIH-HS rats are a stock of genetically heterogeneous animals that have been derived from eight different inbred strains. A rotational breeding schedule has been followed for more than eighty generations, leading to a high level of genetic recombination that makes the NIH-HS rats a unique tool for studying the genetic basis of (biological, behavioral, disease-related) complex traits.

Prepulse inhibition (PPI) and working memory, which are impaired in schizophrenic patients, are among the symptoms/processes modeled in those animal analogs. We have evaluated whether a genetically-selected rat model, the Roman high-avoidance inbred strain (RHA-I), displays PPI deficits as compared with its Roman low-avoidance (RLA-I) counterpart and the genetically heterogeneous NIH-HS rat stock.
