Anestesisykepleieres metoder for å kontrollere cufftrykk – en observasjonsstudie
2021
Bakgrunn: Forskning viser at pasienter i generell anestesi som har fått sine luftveier sikret med en larynxmaske eller en endotrakealtube opplever postoperative pharyngolaryngeale komplikasjoner. Et kontrollert cufftrykk har vist reduksjon i komplikasjoner.
 Hensikt: Hensikten med studien var å undersøke hvilke metoder anestesisykepleiere bruker for å kontrollere cufftrykk, og hvilke begrunnelser de har for å bruke cufftrykkmanometer.
 Metode: Totalt 45 anestesisykepleiere ble observert når de kontrollerte cufftrykket i en endotrakealtube og en larynxmaske. Anestesisykepleierne ble i tillegg spurt om hvilke begrunnelser de hadde for å bruke eller ikke bruke cufftrykkmanometer.�…

Elektronisko pāreju uz zemāko tripleta stāvokli a3Sigma(+) reģistrācija un analīze RbCs un KCs molekulās
2021
Maģistra darbā tika pētītas pārejas no sajauktiem ierosinātiem elektroniskiem stāvokļiem uz a3Σ+ stāvokli RbCs un KCs molekulās. Pielietojot lāzeru inducētās fluorescences (LIF) augstas izšķirtspējas Furjē transformāciju spektroskopiju, RbCs molekulā ir novērotas un analizētas pārejas no A1Σ+~b3Π kompleksa uz a3Σ+, kas ļauj pārliecināties par aprēķināto A~b kompleksa viļņu funkciju precizitāti, kā arī pārbaudīt pārejas dipola momenta funkciju aprēķinu korektumu. KCs molekulā tika novērotas LIF pārejas no c3Σ+ stāvokļa uz a3Σ+ stāvokli. Tas ļāva noteikt c3Σ+ stāvokļa līmeņu enerģijas, kas nepieciešams šī stāvokļa potenciāla iegūšanai. Pāreja c3Σ+ → a3Σ+ tika izmantota arī spektru reģistrācij…
Cannabis Influences the Putative Cytokines-Related Pathway of Epilepsy among Egyptian Epileptic Patients
2019
The study aims to investigate: (1) the prevalence of cannabis among epileptic patients seen at Mansoura University Hospital, (2) serum levels and gene expression of cytokines in epilepsy patients and the controls. and (3) the possibility that cannabis use affects the cytokine levels in epilepsy patients, triggering its future use in treatment. We recruited 440 epilepsy patients and 200 controls matched for age, gender, and ethnicity. Of the epileptic patients, 37.5% demonstrated lifetime cannabis use with a mean duration of 15 ±
Sex Differences in the Behavioral and Synaptic Consequences of a Single in vivo Exposure to the Synthetic Cannabimimetic WIN55,212-2 at Puberty and A…
2019
Heavy cannabis consumption among adolescents is associated with significant and lasting neurobiological, psychological and health consequences that depend on the age of first use. Chronic exposure to cannabinoid agonists during the perinatal period or adolescence alters social behavior and prefrontal cortex (PFC) activity in adult rats. However, sex differences on social behavior as well as PFC synaptic plasticity after acute cannabinoid activation remain poorly explored. Here, we determined that the consequences of a single in vivo exposure to the synthetic cannabimimetic WIN55,212-2 differently affected PFC neuronal and synaptic functions after 24 h in male and female rats during the pube…
Interictal Heart Rate Variability Analysis Reveals Lateralization of Cardiac Autonomic Control in Temporal Lobe Epilepsy.
2020
International audience; Purpose: The temporal lobe, a critical hub for cognition, also plays a central role in the regulation of autonomic cardiovascular functions. Lesions in this area are usually associated with abnormalities in the regulation of heart rate (HR) and blood pressure (BP). The analysis of the heart rate variability (HRV) is useful to evaluate the cardiac parasympathetic nervous system activity. This study aims at comparing HRV changes occurring in two groups of patients suffering from Temporal Lobe Epilepsy (TLE). To that aim, we evaluated patients differentiated by the right or left location of the epileptic foci. Materials and Methods: Fifty-two adult patients with a diagn…
Selective oxidation of aromatic alcohols in the presence of C3N4 photocatalysts derived from the polycondensation of melamine, cyanuric and barbituri…
2021
AbstractA set of C3N4 samples has been prepared by using melamine, cyanuric acid and barbituric acid as the precursors. The materials were subjected both to physical and chemical characterization and were used as photocatalysts for the selective oxidation of aromatic alcohols in water suspension under UV and visible irradiation. The photoactivity of the materials versus the partial oxidation of four substituted benzyl alcohols was investigated. The type and position of the substituents in the aromatic molecule influenced conversion and selectivity to the corresponding aldehyde. The presence of barbituric and cyanuric acids in the preparation method has changed the graphitic-C3N4 structure, …
Photoactive Hybrid Materials based on Conjugated Porous Polymers and Inorganic Nanoparticles
2021
This review explores the current state‐of‐the‐art for functional photoactive hybrids containing inorganic nanoparticles (magnetic and metal) and conjugated organic porous polymers (CPPs). Albeit new in the field, with the first hybrid material of this kind reported in 2012, those materials have gained increasing interest in applications such as sensing, heterogeneous catalysis, photocatalysis, and lithium‐ion batteries (LIBs). This review describes the two main synthetic strategies for those materials, namely, 1) using the chemical and morphological features (e.g., porosity and complexation sites) of CPPs to in situ form nanoparticles and 2) fabricating the nanoparticle for templating CPPs.…
The Impact of Age on the Association Between Physical Activity and White Matter Integrity in Cognitively Healthy Older Adults
2020
Cognition emerges from coordinated processing among distributed cortical brain regions, enabled through interconnected white matter networks. Cortical disconnection caused by age-related decline in white matter integrity (WMI) is likely to contribute to age-related cognitive decline. Physical activity (PA) has been suggested to have beneficial effects on white matter structure. However, its potential to counteract age-related decline in WMI is not yet well established. The present explorative study analyzed if PA was associated with WMI in cognitively healthy older adults and if this association was modulated by age. Forty-four cognitively healthy older individuals (aged 60–88 years) with d…
Neuronal Growth and Behavioral Alterations in Mice Deficient for the Psychiatric Disease-Associated Negr1 Gene
2018
Neuronal growth regulator 1 (NEGR1), a member of the immunoglobulin superfamily cell adhesion molecule subgroup IgLON, has been implicated in neuronal growth and connectivity. In addition, genetic variants in or near the NEGR1 locus have been associated with obesity and more recently with learning difficulties, intellectual disability and psychiatric disorders. However, experimental evidence is lacking to support a possible link between NEGR1, neuronal growth and behavioral abnormalities. Initial expression analysis of NEGR1 mRNA in C57Bl/6 wildtype (WT) mice by in situ hybridization demonstrated marked expression in the entorhinal cortex (EC) and dentate granule cells. In co-cultures of co…
