THz spectroscopy study of amyloid fibrils
2013
In suitable conditions proteins can modify their native conformation and associate to form aggregates with different morphologies in dependence on the external physico-chemical conditions. This phenomenon, one of the most challenging in life sciences, is associated with widely diffused pathologies such as Alzheimer’s, Parkinson’s and Creutzfeldt-Jacob’s diseases. Of particular relevance are ordered elongated aggregates with highly organized patterns of hydrogen-bonds, known as amyloid fibrils. While much biological and structural information are available about amyloids, and in spite of the fundamental paradigm of structure-dynamics-function relation in proteins, much less is known about th…
The new world of biosimilars: what diabetologists need to know about biosimilar insulins
2010
Biosimilar pharmaceuticals are emerging as patent protection on the original biopharmaceutical products expires. However, biopharmaceuticals are particularly complex molecules, and biosimilar insulins present special challenges. In part this reflects their structure and chemical modification after synthesis to attain a biologically active form. Their therapeutic window is narrow and the accuracy of their dosing is highly dependent on the formulation and quality of the administration device. For these reasons, the European Medicines Agency has issued stringent guidelines that must be fulfilled in order to receive approval as a biosimilar soluble insulin. Prescribers should therefore consider…
Efecto de la intervención nutricional en escolares y adolescentes con obesidad con y sin resistencia a la insulina
2020
INTRODUCCIÓN: La obesidad infantil es una enfermedad crónica multifactorial asociada a resistencia a la insulina (RI) responsable de complicaciones metabólicas y vasculares. La intervención precoz es fundamental para frenar su progresión. OBJETIVO: Evaluar el efecto de la intervención nutricional y por actividad física reglada (AFR) personalizadas en escolares y adolescentes con obesidad con y sin RI. METODOLOGÍA: Estudio observacional, analítico, transversal y prospectivo de escolares y adolescentes de 8-17 años con obesidad, en dos fases: a) Fase I: estudio transversal de alteraciones metabólicas y vasculares; b) Fase II: intervención nutricional (12 meses) y combinada con AFR (4 meses). …

Valoración del estado periodontal, perfil inflamatorio y disfunción endotelial en pacientes con Síndrome de Ovario Poliquístico
2022
Las enfermedades periodontales (PDs [del inglés, Periodontal Diseases]) son unas de las enfermedades más frecuentes. Estas patologías, son infecciosas - causadas por bacterias- y su naturaleza de inflamación crónica las ha relacionado con múltiples enfermedades sistémicas. Recientemente, se ha planteado la asociación de las PDs con el Síndrome de Ovario Poliquístico (PCOS [del inglés, Polycistic Ovary Syndrome]). Este síndrome, es un trastorno endocrino complejo cuyo criterio diagnóstico según el Consenso de Róterdam, contempla la presencia de oligo y/o anovulación, signos clínicos y/o bioquímicos de hiperandrogenismo y ovarios de apariencia ecográfica poliquística. La estimulación y secrec…
Muscle Function Differences between Patients with Bulbar and Spinal Onset Amyotrophic Lateral Sclerosis. Does It Depend on Peripheral Glucose?
2021
Background: One of the pathogenic mechanisms of ALS disease is perturbed energy metabolism particularly glucose metabolism. Given the substantial difference in the severity and the prognosis of the disease, depending on whether it has a bulbar or spinal onset, the aim of the study was to determine metabolic differences between both types of ALS, as well as the possible relationship with muscle function. Materials and Methods: A descriptive, analytical, quantitative, and transversal study was carried out in hospitals and Primary Care centers in the region of Valencia, Spain. Fasting glucose and alkaline phosphatase (AP) levels in venous blood, muscle percentage, fat percentage, muscle streng…

Renal function is impaired in normotensive chronic HCV patients: role of insulin resistance.
2015
Renal dysfunction is an independent predictor for cardiovascular morbidity and mortality. We investigated whether chronic hepatitis C virus (HCV) infection and the related insulin resistance/hyperinsulinemia influence renal function in comparison with a group of healthy subjects and with another group with metabolic syndrome. We enrolled 130 newly diagnosed HCV outpatients matched for age and gender with 130 patients with metabolic syndrome and 130 healthy subjects. Renal function was evaluated by calculation of glomerular filtration rate (e-GFR, mL/min/1.73 m2) using the CKD-EPI equation. The following laboratory parameters were measured: fasting plasma glucose and insulin, total, LDL- and…
Experimental and Emerging Free Fatty Acid Receptor Agonists for the Treatment of Type 2 Diabetes
2022
The current management of Type 2 Diabetes Mellitus (T2DM) includes incretin-based treatments able to enhance insulin secretion and peripheral insulin sensitivity as well as improve body mass, inflammation, plasma lipids, blood pressure, and cardiovascular outcomes. Dietary Free Fatty Acids (FFA) regulate metabolic and anti-inflammatory processes through their action on incretins. Selective synthetic ligands for FFA1-4 receptors have been developed as potential treatments for T2DM. To comprehensively review the available evidence for the potential role of FFA receptor agonists in the treatment of T2DM, we performed an electronic database search assessing the association between FFAs, T2DM, i…
Estudio de la variación a largo plazo de los parámetros bioquímicos metabólicos en pacientes con obesidad mórbida e intervenidos mediante bypass gást…
2015
INTRODUCCIÓN La Obesidad es ya uno de los mayores problemas de salud pública en los países occidentales y se prevé que en un futuro cercano sea una verdadera epidemia. La naturaleza de este problema no es estética, como es habitual que se valore en nuestro entorno social. Tiene un sinfín de repercusiones. Empezando por las comorbilidades metabólicas que la acompañan, las complicaciones osteoarticulares que desencadena o simplemente el rechazo social que muchas veces genera. Todo ello sumado, da lugar a una pérdida importante de esperanza de vida y de la calidad de la misma. La consecuencia fundamental de la Obesidad y que provoca el mayor riesgo de morbilidad y, sobre todo de mortalidad, es…
