Study of the mechanisms of oxidative stress, mitochondrial function and endoplasmic reticulum stress in obesity. Role in subclinical atherosclerosis …
2019
El aumento alarmante de la prevalencia de obesidad a nivel mundial y la enorme carga de enfermedad asociada ha generado una creciente demanda de estrategias para frenar la epidemia y / o mitigar los efectos dañinos de la obesidad sobre la salud. Para ello se requiere un compromiso firme y sinérgico por parte de todas las fuerzas sociales, no sólo para desarrollar estrategias preventivas, sino también para contribuir al conocimiento de los eventos patológicos y los mecanismos involucrados en el desarrollo de esta enfermedad. Por ello, el objetivo principal de la presente tesis doctoral es profundizar en los mecanismos subyacentes de la obesidad, especialmente en aquellos relacionados con el …
Relationship between mild to moderate renal dysfunction and obstructive sleep apnea: Data from the European sleep apnea database
2013
The relationship between severity of obstructive sleep apnea (OSA) and kidney function was investigated in the European Sleep Apnea Database (ESADA), where clinical, sleep, and biochemical data of patients studied for suspected OSA in 24 sleep centres of 17 European countries are stored. After excluding patients with missing data or extremely high/low creatinine values, data from 8112 subjects (2328 female) with creatinine values ranging between 0.5 and 2.0 mg% were analyzed. Estimated glomerular filtration rate (eGFR) was obtained with the Modified Diet in Renal Disease (MDRD) equation. Patients were subdivided into two groups: group 1 (n = 3709) studied by full polysomnography; group 2 (n…
Akomodācijas un verģences sistēmas darbības traucējumu izplatība Azerbaidžānā
2020
Maģistra darb ir uzrakstīts angļu valodā uz 35 lpp. Tas satur 19 tabulas, 2 pielikumus un 16 atsauces uz literatūras avotiem. Maģistra darba mērķis ir izvērtēt akomodācijas un verģences traucējumu izplatību un veidus Azerbaidžānas galvaspilsētas baku studentu vidū. Pētījumā piedalījās 192 dalībnieki (15-36 g.v.). Visiem tika veikta bezmaksas redzes pārbaude, kur detalizēti tika izvērtēta refrakcija, akomodācija un verģence. Rezultāti parāda, ka 51 ± 4 % dalībniekiem novēro dažāda veida akomodācijas un verģences darbības traucējumus vai to kombinācijas. Visbiežāk novērotās problēmas ir akomodācijas ekscess un konverģences nepietiekamība. Netiek novērota dzimuma un vecuma ietekme uz akomodāci…
Système olfactif et neurobiologie
2006
Les connaissances neurobiologiques sur l’odorat progressent désormais rapidement depuis la découverte des récepteurs des odorants, remarquables par leur grand nombre et leur diversité. Des réponses sont maintenant apportées aux questions posées par les propriétés originales de la perception olfactive dont beaucoup sont déterminées dès le niveau de l’organe olfactif, et sont fortement déterminées par la génétique. Les connaissances génétiques sur les récepteurs dévoilent une considérable réduction du nombre de gènes olfactifs fonctionnels dans l’espèce humaine et alimentent une réflexion sur l’évolution de l’odorat. Autre avancée riche de promesses : l’application à l’olfaction des méthodes …
Exploring integration prospects of opal-based photonic crystals
2003
Different methods of functionalisation of thin opal films are discussed, including synthesis of opals on pre-patterned substrates, post-synthesis electron beam lithography, preparation of opals with heterogeneous photonic band gap structure and integrating opals with light sources. These approaches have been tested experimentally and key technological problems have been identified.
Recent progress in metal-organic frameworks (MOFs) for CO2 capture at different pressures
2022
Global climate change ensued by the rise in atmospheric CO2 levels is one of the greatest challenges our planet is facing today. This worldwide distress demands technologies that can contribute to our society toward “negative carbon emissions”. Carbon capture and storage (CCS) technologies are in in important role for capturing CO2 from existing emission sources, such as industrial and energy production point sources, before new more prominent modifications to the energy infrastructure can be implemented. Recently, alongside point source capture, direct air capture (DAC) processes have emerged as highly sought-after technologies that are able to capture CO2 from the ambient air. Alongside t…
Operating leverage and the cost of debt in European agri-food firms
2020
Aim of study: To analyse the effect that operating leverage exerts on the cost of debt of agri-food firms in Europe, both in isolation and indirectly through its other risk factors.Area of study: We used panel data made up of 18,360 European firms from 2009 to 2016 (146,880 observations).Material and methods: The data were extracted from the ORBIS database and EUROSTAT. The econometric approach was estimated by the Generalized Method of Moments.Main results: The results obtained confirm that operating leverage or cost structure, in addition to affecting the cost of debt, also affects the relationship between that cost and other sources of risk. More specifically, indebtedness, size, specifi…
Safety of hospital discharge before return of bowel function after elective colorectal surgery
2020
Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…
Modeling epidemics through ladder operators
2020
Highlights • We propose an operatorial model to describe epidemics. • The model describes well the asymptotic numbers of the epidemics. • Ladder operators are used to model exchanges between the “actors” of the system.
