Method for successive absorptions with intestinal perfusion in vivo
(Consejo Superior de Investigaciones Científicas, CSIC, 1979)
A simple technique to study intestinal absorption in vivo, a modification of that of SoLS and PONZ (34), is described. It uses a perfusi on pump, with or without recycling of the solution along the intestinal ...

Liver lipid composition and antioxidant enzyme activities of spontaneously hypertensive rats after ingestion of dietary fats (fish, olive and high-oleic sunflower oils)
(Portland Press, 2001)
Hypertension is associated with greater than normal lipoperoxidation and an imbalance in antioxidant status, suggesting that oxidative stress is important in the pathogenesis of this disease. Although many studies have ...

Interactions between neural progenitor cells and microglia in the subventricular zone: physiological implications in the neurogenic niche and after implantation in the injured brain
(Frontiers Media, 2018)
The adult subventricular zone (SVZ) of the mammalian brain contains neural progenitor cells (NPCs) that continuously produce neuroblasts throughout life. These neuroblasts migrate towards the olfactory bulb where they ...

Aging and Oxidative Stress Decrease Pineal Elongation Factor 2: In Vivo Protective Effect of Melatonin in Young Rats Treated With Cumene Hydroperoxide
(Wiley-Blackwell, 2017)
We studied the alterations of Elongation Factor 2 (eEF2) in the pineal gland of aged rats as well as the possible protective role of exogenous melatonin on these changes in young rats treated with cumene hydroperoxide (CH), ...

Palisade Endings Are a Constant Feature in the Extraocular Muscles of Frontal-Eyed, But Not Lateral-Eyed, Animals
(Association for Research in Vision and Ophthalmology, 2016)
Purpose To test whether palisade endings are a general feature of mammalian extraocular muscles (EOMs). Methods Thirteen species, some frontal-eyed (human, monkey, cat, and ferret), and others lateral-eyed (pig, ...

Controlled attenuation parameter-insulin resistance (CIR) score to predict non-alcoholic steatohepatitis
(Nature Research, 2022-12-19)
The diagnosis of non-alcoholic steatohepatitis (NASH) requires liver biopsy. Patients with NASH are at risk of progression to advanced fibrosis and hepatocellular carcinoma. A reliable non-invasive tool for the detection ...

Advantages and Disadvantages of Apoptosis in the Aging Process
(Wiley-Blackwell, 2019)
Researchers cannot predict as yet how long a human being can live. Life expectancy has been steadily increasing in the last century, but perhaps not always the quality of life in parallel with it. Future generations will ...

Different effects of low selenite and selenium-nanoparticle supplementation on adipose tissue function and insulin secretion in adolescent male rats
(MDPI, 2022)
Adolescence is a period of intense growth and endocrine changes, and obesity and insulin-resistance processes during this period have lately been rising. Selenium (Se) homeostasis is related to lipid metabolism depending ...

A Cholinergic Synaptically Triggered Event Participates in the Generation of Persistent Activity Necessary for Eye Fixation
(Society for Neuroscience, 2004)
An exciting topic regarding integrative properties of the nervous system is how transient motor commands or brief sensory stimuli are able to evoke persistent neuronal changes, mainly as a sustained, tonic action potential ...
