Physical and Quality of Life Changes in Elderly Patients after Laparoscopic Surgery for Colorectal Cancer—A Prospective Cohort Study

2022

Background—The incidence of colorectal cancer is increasing among elderly people, where postoperative complications are frequent. Methods—We evaluated postoperative physical and quality of life changes in elderly patients undergoing laparoscopic surgery for colorectal cancer. A prospective cohort study was performed in 31 colorectal cancer patients ≥60 years who were scheduled for laparoscopic surgery due to colorectal cancer. Outcomes were measured one month preoperative (T1), three days postoperative (T2) and one month postoperative (T3). Results—The largest early postoperative (from T1 to T2) declines were observed for isometric knee extension strength (33.1%), 30 s …

Removal of silicon from CFB-derived fly ash leachate in the context of phosphorus recovery

2018

High concentrations of dissolved silica in the acid leachate impose two major challenges on precipitation based recovery of phosphorus (P). Firstly, co-precipitation of colloidal silica in the acidic regimes decreases the purity and value of precipitated P-products. In addition, silica scaling on internal surfaces of equipment is also a problematic issue in industrial operations. Therefore, removal of dissolved silica prior to P-recovery process minimizes the risks of Si-contamination in P-products and Si-scaling. In the present study, silica removal was achieved by accelerated silica polymerization with higher acidity and ionic strength of mineral acid, which also assisted the leaching of …

Structural and electronic elucidation of a N-heterocyclic silylene vanadocene adduct

2017

The solid and solution state structure of the vanadium(II) N‐ heterocyclic silylene (NHSi) complex, [(SiIPr)V(Cp)2] (1) is reported ( SiIPr: 1,3‐bis(2,6‐diisopropylphenyl)‐1,3‐diaza‐2‐silacyclopent‐4‐ en‐2‐ylidene). The electronic structure of 1 is probed using combination of magnetic measurements, EPR spectroscopy and computational studies. The V–Si bond strength and complex forming mechanism between vanadocene and NHSi ligand is elucidated using computational methods.   peerReviewed

Plēsēju smaržas un mehāniskā kairinājuma izraisītā stresa kāpura stadijā ietekme uz Drosophila melanogaster pieaugušo īpatņu ķermeņa oglekļa un slāpe…

2020

Vispārīgā stresa paradigma paredz, ka plēsonības izraisīts stress ietekmē upuru vielmaiņu, to ķermenim liekot noārdīt enerģētiskās rezerves, kas noved pie pastiprinātas slāpekļa savienojumu izdalīšanas vidē. Darbā novērtēta plēsēja smaržas un mehāniskā kairinājuma ietekme kāpura stadijā uz augļu mušu imago fenotipu. Noskaidrots, ka plēsēja smaržas izraisīts stress samazina mušu ķermeņa masu, palielina slāpekļa koncentrāciju un samazina oglekļa un slāpekļa koncentrāciju attiecību. Līdzīgas fenotipa izmaiņas iepriekš novērotas audzējot kāpurus kopā ar dzīvu zirnekli un liecina, ka kāpuru ožai plēsēja atpazīšanā ir būtiskāka nozīme nekā citām maņām. Rezultāti ir pretrunā vispārīgajai stresa pa…

Prevalence of Pneumococcal Serotypes in Community-Acquired Pneumonia among Older Adults in Italy: A Multicenter Cohort Study

2022

Pneumococcal community-acquired pneumonia (CAP) is a leading cause of mortality. Following the introduction of pneumococcal conjugate vaccines (PCVs) in children, a decrease in the burden of the disease was reported. In parallel, an increase in non-vaccine serotypes was also noted. The objective of this study was to assess the current serotype-specific epidemiology of pneumococci among Italian older adults hospitalized for CAP. A prospective study was conducted between 2017 and 2020 in four Italian regions. Subjects aged ≥65 years hospitalized with confirmed CAP were tested for pneumococci using both pneumococcal urinary antigen and serotype-specific urine antigen tests able to identify all…

Policijas darba stress un pāru attiecības

2021

Bakalaura darbā tika noskaidrots, vai pastāv statistiski nozīmīgas saistības starp policistu darba stresu un pāru attiecību kvalitāti. Pētījumā piedalījās (N=52) policijas darbinieki vecumā no 25-60 (M=41), (SD=8,90). Tika papildus ievākti demogrāfiskie dati, grupējot pēc dzimuma, izglītības līmeņa un attiecību statusa.

Effects of Polyacrylic Acid Pre-Treatment on Bonded-Dentine Interfaces Created with a Modern Bioactive Resin-Modified Glass Ionomer Cement and Subjec…

2018

Objectives: Resin-modified glass ionomer cements (RMGIC) are considered excellent restorative materials with unique therapeutic and anti-cariogenic activity. However, concerns exist regarding the use of polyacrylic acid as a dentine conditioner as it may influence the bonding performance of RMGIC. The aim of this study was to evaluate the effect of different protocols for cycling mechanical stress on the bond durability and interfacial ultramorphology of a modern RMGIC applied to dentine pre-treated with/without polyacrylic acid conditioner (PAA). Methods: The RMGIC was applied onto human dentine specimens prepared with silicon-carbide (SiC) abrasive paper with or without the use of a PAA c…

Determinación de Streptococcus Mutans y Streptococcus Sobrinus, mediante pcr cuantitativa a tiempo real, y su relación con la caries dental en escola…

2013

La caries dental presenta una etiología multifactorial, los factores ambientales, los hábitos de alimentación, higiene bucal y la susceptibilidad genética individual, juegan un papel importante en el desarrollo de esta enfermedad (1). Los Streptococcus mutans y Streptococcus sobrinus están fuertemente implicados en la aparición de la caries dental en humanos. Numerosos estudios han demostrado que la asociación de S. mutans y S. sobrinus conlleva niveles más altos de caries (2-4) y varios estudios han encontrado que la prevalencia deS. sobrinus está fuertemente asociada con mayor actividad de caries que la delS. mutans (5-6). Se considera que la determinación de estas dos especies en la infa…

La música como herramienta de educación ciudadana

2013

Resumen basado en el de la publicación La asignatura de música en primaria y secundaria tiene un papel destacado en el proceso de adquisición de la competencia social y ciudadana. Desde la aparición de la Ley Orgánica de Educación (LOE), todas las asignaturas han tenido que adaptarse para poder contribuir a la adquisición de cada una de ellas; sin embargo, la asignatura de música debido a sus características metodológicas, conceptuales y actitudinales, es la que única que puede contribuir a la adquisición de las ocho competencias básicas sin sufrir una radical transformación curricular.
