CAMKIIγ suppresses an efferocytosis pathway in macrophages and promotes atherosclerotic plaque necrosis

2017

Atherosclerosis is the underlying etiology of cardiovascular disease, the leading cause of death worldwide. Atherosclerosis is a heterogeneous disease in which only a small fraction of lesions lead to heart attack, stroke, or sudden cardiac death. A distinct type of plaque containing large necrotic cores with thin fibrous caps often precipitates these acute events. Here, we show that Ca2+/calmodulin-dependent protein kinase gamma (CaMKII gamma) in macrophages plays a major role in the development of necrotic, thin-capped plaques. Macrophages in necrotic and symptomatic atherosclerotic plaques in humans as well as advanced atherosclerotic lesions in mice demonstrated activation of CaMKII. We…

Omega-3 long-chain polyunsaturated fatty acids intake in children : the role of family-related social determinants

2020

Omega-3 long-chain polyunsaturated fatty acids play a central role in neuronal growth and in the development of the human brain, since they are essential elements which depend on intake through diet to ensure an adequate amount. Fish and seafood are the main dietary sources of these fatty acids in Spain and in other countries. In order to assess the effect of the intake of common foods containing high amounts of omega-3 polyunsaturated fatty acids, a food frequency questionnaire was administered to parents of children and adolescents attending a primary school in Valencia (Spain), and the intake of dietary omega-3 such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) was estima…

A free radical theory of frailty.

2018

The free radical theory of ageing provided an intellectual framework for many laboratories working on ageing. However, experimental and clinical evidence showing that high doses of antioxidants do not have an effect on ageing or on age-associated diseases, cast doubts on the validity of this theory. Data from our own laboratory show that oxidative damage does not correlate with age, especially in the geriatric population, but rather with the frailty state. This has led us to postulate the free radical theory of frailty that proposes that oxidative damage is associated with frailty, but not with chronological age itself. Superoxide dismutase deficient mice are more frail than controls. But m…

Carbohydrate-deficient transferrin (CDT) and HDL cholesterol (HDL) are highly correlated in male alcohol dependent patients.

2000

Background: Serum levels of total HDL cholesterol (HDL) are reportedly influenced by recent alcohol intake. We examined the correlation between HDL cholesterol and widely used markers of excessive alcohol intake, such as carbohydrate-deficient transferrin (CDT), γ-glutamyl-transferase (GGT), or mean corpuscular volume of erythrocytes (MCV), of which CDT is thought to be the most specific. Methods: Several serological markers [i.e., CDT, GGT, aspartate aminotransferase (ASAT), alanine aminotransferase (ALAT), MCV, and HDL] were determined in 100 actively drinking male patients with alcohol dependence (DSM-IV) and in 27 non-alcohol-dependent controls, according to routine procedures. Spearman…

Vitamin B12 and hepatic enzyme serum levels correlate in male alcohol-dependent patients.

2001

- Vitamin B12 serum levels and markers for alcohol consumption were determined in 80 male alcohol-dependent patients. Spearman correlation coefficients (r(S)) were calculated. Significant positive correlations between vitamin B12 and hepatic enzyme values were found (gamma-glutamyltransferase: r(S) = 0.58; alanine aminotransferase: r(S) = 0.43; aspartate aminotransferase: r(S) = 0.47; glutamate dehydrogenase: r(S) = 0.43; all P:0.001). Therefore, for a proper interpretation of vitamin B12 levels, it may be clinically relevant to take markers of hepatocellular damage into account.

The value of MRI in the evaluation of the ACL deficient knee and in the post-operative evaluation after ACL reconstruction

1993

To evaluate the usefulness of magnetic resonance imaging (MRI) in the exploration of the anterior cruciate ligament (ACL) deficient-knee, a total of twenty-five patients with chronic instability of the knee joint and who underwent both MRI and arthroscopy were studied prospectively. Twenty-three of these patients underwent an intra-articular reconstruction of the ACL with bone-patellar tendon-bone autografts. For the ACL lesions MRI had a sensitivity of 95.8%, a specificity of 100% and a diagnostic accuracy of 97.7%. Associated bowing of the PCL was seen in 20 cases of the study group. For the associated meniscal lesions MRI had a sensitivity of 77.7%, a specificity of 94.7% and a diagnosti…

Iron-dependent erythropoiesis in women with excessive menstrual blood losses and women with normal menses

2013

In women of fertile age, iron loss consequent to excessive menstrual discharge is by far the most frequent cause of iron-deficient anemia. However, the relationship between menstrual discharge and iron loss is poorly understood. In this prospective study, total menstrual and iron losses were assayed in a large cohort of non-anemic women and women with excessive menstrual blood losses (menorrhagia) in order to provide data useful for intervention. One hundred and five Caucasian women aged 20–45 years were recruited. Blood cell count and serum ferritin (SF) levels were determined in each case before menses. Menstrual fluid losses (MFL) were determined using a standardized pads’ weight method.…

Una propuesta de intervención para niños con trastorno del espectro autista a través de la lectura dialógica y la realidad aumentada

2020

Los niños con trastorno del espectro autista (TEA) requieren intervenciones educativas basadas en la evidencia que traten las dificultades en la atención conjunta, la reciprocidad social, la comunicación, las habilidades mentalistas o el funcionamiento ejecutivo, al tiempo que consideren sus fortalezas en el procesamiento visual y su estilo de aprendizaje. Una intervención que reúne estas cualidades es la técnica de la lectura dialógica de cuentos, como sugieren recientes investigaciones con resultados prometedores. Además, su combinación con nuevas tecnologías como la realidad aumentada puede incrementar la motivación de los niños hacia la tarea y favorecer el aprendizaje. En este artículo…
