Expression of Adenosine A2B Receptor and Adenosine Deaminase in Rabbit Gastric Mucosa ECL Cells
(MDPI, 2017-04)
Adenosine is readily available to the glandular epithelium of the stomach. Formed continuously in intracellular and extracellular locations, it is notably produced from ATP released in enteric cotransmission. Adenosine ...
Piper and Vismia Species from Colombian Amazonia Differentially Affect Cell Proliferation of Hepatocarcinoma Cells
(MDPI, 2015-01)
There is an increasing interest to identify plant-derived natural products with antitumor activities. In this work, we have studied the effects of aqueous leaf extracts from Amazonian Vismia and Piper species on human ...
Adenosine: direct and indirect actions on gastric acid secretion
(Frontiers Media, 2017-09-22)
Composed by a molecule of adenine and a molecule of ribose, adenosine is a paradigm of recyclable nucleoside with a multiplicity of functions that occupies a privileged position in the metabolic and regulatory contexts. ...
Influence Of Oxygen Partial Pressure On The Characteristics Of Human Hepatocarcinoma Cells
(Elsevier Science BV, 2017-08)
Most of the in vitro studies using liver cell lines have been performed under atmospheric oxygen partial pressure (21% O-2). However, the oxygen concentrations in the liver and cancer cells are far from this value. In the ...
Physical activity and fitness are associated with verbal memory, quality of life and depression among nursing home residents: preliminary data of a randomized controlled trial
(Biomed Central, 2018-03-27)
Background: Few studies have simultaneously examined changes in physical, cognitive and emotional performance throughout the aging process.
Methods: Baseline data from an ongoing experimental randomized study were ...
Unraveling the In Vitro Antitumor Activity of Vismia Baccifera Against HepG2: Role of Hydrogen Peroxide
(Elsevier, 2018-06-27)
Currently natural products derived from plants are receiving huge attention because of their antitumor activities. In previous work we reported that an aqueous leaf extract of Vismia baccifera induced toxicity in HepG2. ...
Effectiveness of a multicomponent exercise program in the attenuation of frailty in long-term nursing home residents: study protocol for a randomized clinical controlled trial
(Biomed Central, 2017-02-23)
Background: There is increasing evidence suggesting that cognition and physical frailty interact within a cycle of decline associated with aging which has been called cognitive frailty. Exercise programs have demonstrated ...
Physical Activity, Physical Fitness, Body Composition, And Nutrition Are Associated With Bone Status In University Students
(MDPI, 2018-01-10)
Understanding the modifiable factors that improve and maximize peak bone mass at an early age is necessary to design more effective intervention programs to prevent osteoporosis. To identify these modifiable factors, we ...
Health-related quality of life, handgrip strength and falls during detraining in elderly habitual exercisers
(Biomed Central, 2017-11-21)
Background: The effects of regular exercise on physical functioning and health-related quality of life (HRQOL) have been thoroughly studied. In contrast, little is known about the changes which occur following cessation ...
Analysis of Protein Oxidative Modifications in Follicular Fluid from Fertile Women: Natural Versus Stimulated Cycles
(MDPI, 2018-11-27)
Oxidative stress is associated with obstetric complications during ovarian hyperstimulation in women undergoing in vitro fertilization. The follicular fluid contains high levels of proteins, which are the main targets of ...
