Profiling development of burnout over eight years: relation with job demands and resources
2020
The aim of the present study was twofold: First, to profile the long-term development of burnout symptoms (exhaustion, cynicism and reduced professional efficacy), and second, to investigate the associations of developmental burnout profiles with job demands and resources. The study focused on Finnish white-collar professionals (N = 169) who participated in a survey five times during eight years (in 2006, 2008, 2010, 2012, and 2014). At each measurement time, the participants filled in the same scales of burnout, job demands and job resources. Using Latent Profile Analysis (LPA), three developmental profiles of burnout symptoms were identified: 1) Stable, low burnout (78%), 2) Exhaustion in…
Organizational Initiatives for Promoting Employee Work-Life Reconciliation Over the Life Course. A Systematic Review of Intervention Studies
2016
This review aimed to explore the initiatives, interventions, and experiments implemented by employing organizations and designed to support the work-life reconciliation at workplaces, and the effects of these actions on employees’ well-being at work. A systematic literature review was conducted on the basis of a search in PsycInfo, ERIC, and the ISI Web of Science database of Social Sciences between January 2000 and May 2015. Those studies were included in which either organizational or individual-level initiatives, interventions, or experiments were implemented by employers at workplaces in order to promote the work-life reconciliation of their employees. Work-life reconciliation was consi…
A skeletal Class III malocclusion with agenesis and canine-bicuspid transposition: a nonsurgical approach
2021
Abstract Background The present case report describes the orthodontic management of a patient who presented with a skeletal Class III malocclusion combined with other dental anomalies. The malocclusion was complicated by agenic maxillary lateral incisors and a lower right second premolar, in company with the transposition of the maxillary canines and premolars. Methods Dentoalveolar compensation of the anteroposterior jaw relationship was performed. The upper deciduous lateral incisors were extracted and the spaces closed, so that the first premolars replaced the missing lateral incisors while the canine transposition was maintained Results Satisfactory results were obtained which provided …
Biomechanical Study of the Osteoporotic Spine Fracture: Optical Approach
2021
Background and objectives: Osteoporotic spine fractures represent a significant factor for decreasing quality of life in the elderly female population. Understanding the mechanisms involved in producing these fractures can improve their prevention and treatment. This study presents a biomechanical method to produce a vertebral fracture, conducted on a human spine segment, observing the displacements and strains in the intervertebral disc, endplate, and vertebral body. Materials and Methods: We performed two tests, one corresponding to an extension loading, and the second to an axial loading. Results: The maximum displacement in the target vertebral body presented higher values in the case o…
A systematic analysis of evidence for surgically accelerated orthodontics
2019
Background Corticotomy is a technique presumed as useful to decrease the time for orthodontic treatment, however, it is necessary to do a systematic review in order to determine if there is enough scientific evidence to back up the use of Corticotomy to accelerate the treatment. Material and methods Data was stockpiled from the electronic database such as PubMed, Cochrane, Scopus y Science Direct, according to the PRISMA linings for systematic reviews, using the following keywords: accelerated movement of the teeth AND osteotomy AND piezocision AND corticotomy AND orthodontics. Only English, Spanish and French language articles that met the criteria needed were included. Results In the diff…
Palatal fenestration after orthodontic treatment. Intermodal approach and evolution. A case report
2018
A 15-year-old patient is referred to the Department of Periodontics of the University of Valencia. The patient reported dissatisfaction with the position of upper right canine after orthodontic treatment. Previously, in a private center, surgical approaches were performed for the traction of the canine included. On clinical examination at first appointment, generalized plaque-induced gingivitis was observed, with palatal fenestration of the root of upper right lateral incisor of approximately 75% of the total surface, with suppuration and very little gingiva inserted at the cervical level, which presents a buccal torque of the crown. Radiologically, a mild rhizolysis and bone loss adjacent …
Fetal Calf Serum-Free Generation of Functionally Active Murine Dendritic Cells Suitable for In Vivo Therapeutic Approaches
2000
Standard protocols to generate mouse dendritic cells (DC) generally use culture medium supplemented with fetal calf serum; however, reinjection in vivo of DC cultured in fetal calf serum results in priming to xenogeneic proteins that clearly limits the use of such DC. We therefore established a fetal calf serum-free culture system for the generation of murine DC from bone marrow precursors. DC can be generated fetal calf serum-free using RPMI supplemented with 1.5% syngeneic mouse serum. Although the yield of DC grown under fetal calf serum-free conditions was somewhat lower than that of the standard culture, large numbers of DC could be generated without the exposure to xenogeneic proteins…
Green Extraction of Polyphenols from Waste Bentonite to Produce Functional Antioxidant Excipients for Cosmetic and Pharmaceutical Purposes: A Waste-t…
2022
In an ever-growing perspective of circular economy, the development of conscious, sustainable and environmental-friendly strategies to recycle the waste products is the key point. The scope of this work was to validate the waste bentonite from the grape processing industries as a precious matrix to extract polyphenols by applying a waste-to-market approach aimed at producing novel functional excipients. The waste bentonite was recovered after the fining process and opportunely pre-treated. Subsequently, both the freeze dried and the so-called “wet” bentonites were subjected to maceration. PEG200 and Propylene Glycol were selected as solvents due to their ability to dissolve poly…
Plantācijas kārklu mizas apstrāde, izmantojot ekstrakciju un organosolv delignifikāciju, kā rīku fitoķimikāliju ieguvei.
2019
Literatūras apskatā apkopota informācija par kārklu izplatību Latvijā, to izmantošanas iespējām, kā arī par kārklu mizas ķīmisko sastāvu. Apkopota informācija par biorafinācijas principu un par lignocelulozes pamatkomponentu noteikšanas metodēm. Darba eksperimentālajā daļā veikts vairāku plantācijas kārklu šķirņu salīdzinājums. Veiktas plantācijas kārklu “Klara” mizas ekstrakcijas, izmantojot divus dažādus ekstrakcijas režīmus, salīdzināti iegūtie rezultāti, kā arī veikta iegūto ekstraktu raksturošana, nosakot kopējo polifenolu daudzumu, kopējo proantocianidīnu daudzumu, kā arī veikta individuālu savienojumu identifikācija, izmantojot UHPLC-MS/MS sistēmu. Analizēti iegūtie mizas atlikumi pē…
Painful scar neuropathy: principles of diagnosis and treatment
2015
Nerve-tissue interactions are critical. Peripheral nerve injuries may involve intraneural and extraneural scar formation and affect nerve gliding planes, sometimes leading to complex clinical presentations. All of these pathological entities involve pain as the main clinical symptom and can be subsumed under the term "painful scar neuropathy". The authors review the literature on treatment approaches to peripheral nerve scar neuropathy and the outcomes of neurolysis-associated procedures and propose a simple classification and a therapeutic approach to scar neuropathy. The search retrieved twenty-one papers, twenty of which reported pain reduction or resolution with various techniques. Ther…
