Expired Tidal Volume and Respiratory Rate During Postnatal Stabilization of Newborn Infants Born at Term via Cesarean Delivery

2021

Objective To retrieve evolving respiratory measures in the first minutes after birth in normal neonates born at term using a respiratory function monitor. Study design We evaluated newborn babies delivered at term via cesarean after uncomplicated pregnancies. Immediately after birth, a respiratory function monitor with an adapted flowmeter and a face mask were applied at 2, 5, and 10 minutes after birth for 90 seconds in each period. We analyzed expired and inspired tidal volume, respiratory rate (RR), percentage of leakage, and number of analyzed breaths in each individual infant's recording using a respiratory research software. Results A total of 243 infants completed the study. The fina…

Towards an International Economic Security Regime for Alternative Development in Illicit Drug Producing Countries: Exploring International Support fo…

2013

Esta investigación explora la estrategia de la reducción de la oferta dentro del contexto del fenómeno global de las drogas ilícitas. Tiene un enfoque especial en las políticas nacionales e internacionales del desarrollo alternativo y de comercio que pretenden reducir la oferta de plantas narcóticas, drogas y sustancias psicotrópicas a través de políticas de desarrollo económico en países productores. El argumento central de la investigación es que se podría considerar Colombia como un punto de referencia para establecer un régimen internacional eficaz de apoyo transfronterizo para estrategias de desarrollo alternativo para abordar la oferta de drogas ilícitas por el mundo. Este régimen -un…

Targeting the mevalonate pathway for improved anticancer therapy.

2009

The mevalonate pathway is important for the generation of isoprene moieties thereby providing the basis for the biosynthesis of molecules required for maintaining membrane integrity, steroid production and cell respiration. Additionally, isoprene precursors are indispensable for the prenylation of regulatory proteins such as Ras and Ras-homologous (Rho) GTPases. These low molecular GTP-binding proteins play key roles in numerous signal transduction pathways stimulated upon activation of cell surface receptors by ligand binding. Thus, Ras/Rho proteins eventually regulate cell proliferation, tumor progression and cell death induced by anticancer therapeutics. Lipid modification of Ras/Rho pro…

Olive oil intake and risk of cardiovascular disease and mortality in the PREDIMED Study

2014

[Background] It is unknown whether individuals at high cardiovascular risk sustain a benefit in cardiovascular disease from increased olive oil consumption. The aim was to assess the association between total olive oil intake, its varieties (extra virgin and common olive oil) and the risk of cardiovascular disease and mortality in a Mediterranean population at high cardiovascular risk.

Interconnections among inflammation, chronic liver disease and HIV: understanding the hepatoprotective effects of the antiretroviral drug rilpivirine

2022

INTRODUCCIÓN Durante las últimas décadas, la utilización de la terapia antirretroviral combinada (TARc) para combatir la infección por el virus de la inmunodeficiencia humana (VIH) ha convertido esta enfermedad en una patología crónica. A pesar de que la TARc ha mejorado enormemente la calidad de vida de los pacientes, según diversos estudios epidemiológicos, estos pacientes envejecen antes y sufren de enfermedades relacionadas con la edad como cáncer, osteoporosis, enfermedades metabólicas (diabetes mellitus y enfermedad hepática) y patologías neurodegenerativas aparecen a edades más tempranas que la población no infectada. Los mecanismos responsables de este fenómeno aún no se conocen, si…

The Influence of Nanoparticle Shape on Protein Corona Formation

2020

Nanoparticles have become an important utility in many areas of medical treatment such as targeted drug and treatment delivery as well as imaging and diagnostics. These advances require a complete understanding of nanoparticles' fate once placed in the body. Upon exposure to blood, proteins adsorb onto the nanoparticles surface and form a protein corona, which determines the particles' biological fate. This study reports on the protein corona formation from blood serum and plasma on spherical and rod‐shaped nanoparticles. These two types of mesoporous silica nanoparticles have identical chemistry, porosity, surface potential, and size in the y ‐dimension, one being a sphere and the other a …

Ultrasound bioeffects in rats: quantification of cellular damage in the fetal liver after pulsed Doppler imaging

2011

Objective To determine whether pulsed Doppler examination of the ductus venosus in rat fetuses could damage exposed tissue. Methods On gestational day 18, the livers of a mean of approximately five fetuses per mother (n = 5.14, SD = 1.6), in a cohort of 35 pregnant female rats, were exposed individually to pulsed Doppler and these were considered the 'exposed group'. The remaining fetuses in each pregnant rat (n = 5.16, SD = 2.1) formed the 'control group'. We tested for 600, 300, 60, 20, 15, 10 and 3 s of exposure of the fetal ductus venosus and the damage was evaluated measuring a cell death index of apoptotic activity at 7 h post-exposure (n = 16). In addition, subgroups of mothers were …
