Role of CD1A and HSP60 in the antitumoral response of oesophageal cancer

2011

Oesophageal cancer (OC) is one of the most common and severe forms of tumor. A wider knowledge of molecular mechanisms which lead to a normal epithelium becoming a neoplasm may reveal new strategies to improve treatment and outcome of this disease. In this review, we report recent findings concerning molecular events which take place during carcinogenesis of the oesophagus. In particular, we focus on the role of two molecules, CD1a and Hsp60, which are overexpressed in oesophageal and many other types of tumor. Both molecules may present tumor antigens and promote in situ the stimulation of an antitumoral immune activity. We suggest there is a synergistic action between these molecules. Fur…

Emotional intelligence in children with severe sleep-related breathing disorders

2019

Background. Obstructive sleep apnea syndrome (OSAS) affects up to 4% of a pediatric population, with many comorbidities in the medium-long term. Functional alterations in the prefrontal cortex (PFC) may explain why OSAS impacts aspects such as executive functions, memory, motor control, attention, visual-spatial skills, learning, and mood regulation. Emotional intelligence (EI) is a complex neuropsychological function that could be impaired in many clinical conditions. Purpose. The aim of the study is to evaluate the difference in emotional intelligence skills among children with OSAS and healthy subjects (nOSAS). Methods. 129 children (72 males; mean age 7.64±1.98 years) affected by OSAS w…

Parental Stress and Parental Ratings of Behavioral Problems of Enuretic Children.

2019

Background: Primary monosymptomatic nocturnal enuresis (PMNE) may have a stressful impact on the everyday life of children and parents, and it may represent a cumulative stress factor increasing feelings of "learned helplessness." Methods: The current study investigated parental stress in a group of parents (n = 330) of children affected by PMNE, compared to a group of parents (n = 330) of typical developing children (TDC). In addition, the study evaluated whether parents of PMNE children experience more emotional, social, and behavioral problems in their children, compared to parents of TDC. Finally, the study correlated frequency of enuresis with stress values and Child Behavior Checklist…

Non-coding RNAs and other determinants of neuroinflammation and endothelial dysfunction: regulation of gene expression in the acute phase of ischemic…

2021

Ischemic stroke occurs under a variety of clinical conditions and has different pathogeneses, resulting in necrosis of brain parenchyma. Stroke pathogenesis is characterized by neuroinflammation and endothelial dysfunction. Some of the main processes triggered in the early stages of ischemic damage are the rapid activation of resident inflammatory cells (microglia, astrocytes and endothelial cells), inflammatory cytokines, and translocation of intercellular nuclear factors. Inflammation in stroke includes all the processes mentioned above, and it consists of either protective or detrimental effects concerning the “polarization” of these processes. This polarization comes out from the intera…

Pro-inflammatory CX3CR1+ CD59+ TL1A+ IL-23+ monocytes are expanded in patients with Ankylosing Spondylitis and modulate ILC3 immune functions

2018

Gut derived ILC3 have been demonstrated to participate in AS pathogenesis. CX3CR1+ mononuclear phagocytes (MNP) have been demonstrated to modulate ILC3 function in the gut. The aim of this study was to study the role of pro-inflammatory CX3CR1+ CD59+ MNP in modulating ILC3 function in AS patients.

Effects of low frequency electric fields on synaptic integration in hippocampal CA1 pyramidal neurons: implications for power line emissions

2014

The possible cognitive effects of low frequency external electric fields, such as those generated by power lines, are poorly understood. Their functional consequences for mechanisms at the single neuron level are very difficult to study and identify experimentally, especially in vivo. The major open problem is that experimental investigations on humans have given inconsistent or contradictory results, making it difficult to estimate the possible effects of external low frequency electric fields on cognitive functions. Here we investigate this issue with a realistic model of hippocampal CA1 pyramidal neurons. The model suggests how and why external electric fields, with environmentally obser…

Two-year retrospective analysis of the international impact of Journal of Optometry: part II

2011

The Journal of Optometry – Peer-reviewed Journal of the Spanish General Council of Optometrists- was launched in March 2008 publishing the first issue by September 2008. It is now reaching 2.5 years of activity in spreading clinical and scientific knowledge in the field of Optometry and Visual Science and related areas. Despite this short path within the international scientific publication scenario, it is appropriate to stop and reflect about the challenges, achievements and the numbers that are making J Optom a reference in this competitive area. In this editorial we will discuss the steps followed to setup the journal and the actual international impact in terms of audience from the read…

Turnover and availability of soil organic carbon under different Mediterranean land-uses as estimated by 13C natural abundance

2013

Summary Soil organic matter (SOM) is an important factor in ecosystem stability and productivity. This is especially the case for Mediterranean soils suffering from the impact of humans and degradation as well as harsh climatic conditions. We used the carbon (C) exchange resulting from C3-C4 and C4-C3 vegetation change under field conditions combined with incubations under controlled conditions to evaluate the turnover and availability of soil organic C under different land-uses. The 40-year succession of Hyparrenia hirta L. (C4 photosynthesis) after more than 85 years of olive (Olea europaea L.) tree (C3 photosynthesis) growth led to the exchange of 54% of soil organic C from C3 to C4 form…
