Background: Oxidative stress is involved in the pathophysiology of several diseases such as cardiovascular disorders, cancer, neurodegeneration.Aims and Objectives: Our study evaluated the oxidant/antioxidant status on a cohort of healthy patients matched with some independent variables as a basic individual redox balance monitor on a disease-prevention perspective.Materials and Methods: The anecdotic, retrospective and observational study included 200 apparently healthy volunteers after formal informed consent release whose personal history and physical examination had been recorded specifically on the following items: age, previous diseases, sport activities, smoking habit, balanced/unbalanced nutrition, current absence/presence of inflammatory processes, oral health hygiene, administration of oral contraceptives or hormone replacement therapy in postmenopausal women. No drug treatment was admitted in the recruited patients, up to 6 months before the evaluation. The laboratory instruments used were Point of care FRAS 4 Evolvo (H&D, Parma, Italy) measuring the oxidative stress in plasma samples and antioxidant capacity in plasma and saliva samples.Results: Two-hundred patients were recruited. Statistically relevant differences were observed in oxidative stress-related variables, namely a significant relationship between plasma oxidative stress level and female gender (p

Desmodium adscendens (Desmodium) is a plant that possesses anti-allergic, antioxidant and hepato-protective properties. Lithothamnium calcareum (Lithothamnium) is a calcified seaweed that possesses remineralization properties and the ability to maintain homeostasis.Aim: In this single-arm study, we investigated the efficacy of a combination therapy based on Desmovit® which contains Desmodium and Lithothamnium, and chemotherapy in patients with head and neck cancer.Methods: Twelve patients with histological or cytological diagnosis of stage IV head and neck cancer were enrolled in this study that was approved by the ethics committee of the Unità Operativa Complessa (UOC) di Oncologia Medica Azienda Ospedaliera Ospedali Riuniti Marche Nord and followed the Declaration of Helsinki guidelines. The patients were monitored by investigation of the performance status according to the Glasgow Prognostic Score (GPS), which evaluates the plasma level of C-reactive protein and albumin levels, and the Eastern Cooperative Oncology Group (ECOG) examination. Pain and fatigue were also monitored using the visual analog scale and visual analog fatigue scale, respectively. All the above parameters were assessed biweekly to week 10.Results: GPS, ECOG, and albumin remained stable throughout the study with a trend towards a decrease in GPS and albumin at week 10 post-treatment. Pain significantly improved at week 8 (P

Duchenne muscular dystrophy (DMD) is an inherited fatal X-linked myogenic disorder with a prevalence of 1 in 3500 male live births. It affects voluntary muscles, and heart and breathing muscles. DMD is characterized by continuous degeneration and regeneration cycles resulting in extensive fibrosis and a progressive reduction in muscle mass. Since the identification of a reduction in dystrophin protein as the cause of this disorder, numerous innovative and experimental therapies, focusing on increasing the levels of dystrophin, have been proposed, but the clinical improvement has been unsatisfactory. Dystrophin forms the dystrophin-associated glycoprotein complex and its proteins have been studied as a promising novel therapeutic target to treat DMD. Among these proteins, cell surface glycosaminoglycans (GAGs) are found almost ubiquitously on the surface and in the extracellular matrix (ECM) of mammalian cells. These macromolecules interact with numerous ligands, including ECM constituents, adhesion molecules and growth factors that play a crucial role in muscle development and maintenance. In this article, we have reviewed in vitro, in vivo and clinical studies focused on the functional role of GAGs in the pathophysiology of DMD with the final aim of summarizing the state of the art of GAG dysregulation within the ECM in DMD and discussing future therapeutic perspectives.

Introduction: zeolites (clinoptilolites) are a family of alluminosilicates and cations clustered to form macro aggregates by small individual cavities. In the medical area they are involved in detoxification mechanisms capturing ions and molecules into their holes. Actually, we classify about 140 types of natural and 150 synthetic zeolites, for specific and selective use. Clinoptilolite is a natural zeolite and it is the most widespread compound in the medical market. Objective: this review analyzes the main fields of zeolite utilization. Methods: we searched Pubmed/Medline using the terms "zeolite" and "clinoptilolite". Results and discussion: in zoothechnology and veterinary medicine zeolite improves the pets' fitness, removes radioactive elements, aflatoxines and poisons. Zeolite displays also antioxidant, whitening, hemostatic and anti-diarrhoic properties, projected in human care. However very scanty clinical studies have been run up to now in immunodeficiency, oncology after chemotherapy and radiotherapy as adjuvants. Conclusions: further clinical investigations are urgently required after this review article publication which updates the state of the art. Introducción: las zeolitas (clinoptilolitas) son una familia de aluminosilicatos y cationes agrupada para formar agregados macro de pequeñas cavidades individuales. En el área médica están involucrados en los mecanismos de desintoxicación y en capturar iones y moléculas en sus agujeros. En realidad, clasificamos cerca de 140 tipos de zeolitas naturales y 150 sintéticas, para usos específicos y selectivos. La clinoptilolita es una zeolita natural y es el compuesto más extendido en el mercado médico. Objetivo: esta revisión analiza los principales campos de utilización de la zeolita. Métodos: se realizaron búsquedas en Pubmed/Medline usando los términos "zeolita" y "clinoptilolita". Resultados y discusión: en zootecnología y medicina veterinaria la zeolita mejora la condición de la mascota, elimina los elementos radiactivos, las aflatoxinas y los venenos. En el cuidado humano, la zeolita también muestra propiedades antioxidantes, de blanqueamiento, homeostáticas y antidiarreicas. Sin embargo, los estudios clínicos que se han llevado a cabo hasta ahora como adyuvante en inmunodeficiencia y tras la quimioterapia y la radioterapia en oncología son muy escasos. Conclusiones: se requieren con urgencia otras investigaciones clínicas después de esta publicación del artículo que actualicen el estado de la técnica.

Great interest is raising in food intolerances due to the lack, in many cases, of a particular sensitizing agent.We investigated the serum level of possible new haptens in 15 heavy meat consumers for sport fitness affected by various kinds of food intolerance and who had ever been administered antibiotics in their life for clinical problems.Forty ml of blood were drawn from each patient and analyzed, by means of an ELISA test, in order to possibly identify the presence of an undue contaminant with hapten properties.Four out of fifteen subjects (26%) showed a serum oxytetracycline amount6 ng/g (which is considered the safety limit), 10 of 15 (66%) a serum doxycycline amountof 6 ng/g and 3 out of 15 (30%) subjects had high serum level of both molecules.Although a direct ratio between body antibiotics remnant storage in the long run and chronic gut dysfunctions and/or food allergy did not reached the evidence yet, the blood traces of these compounds in a food intolerant otherwise healthy population might be considered the preliminary putative step of a sensitizing pathway. Our next goals foresee a deeper insight into the sensitizing trigger from human chronic antibiotic exposure via the zootechnical delivery of poultry food.La falta, en muchos casos, de un agente sensibilizador está despertando un enorme interés en la tolerancia a los alimentos.Investigamos el nivel sérico de posibles nuevos haptenos en 15 grandes consumidores de carne para entrenamiento deportivo afectados por diversos tipos de intolerancia a los alimentos y que habían recibido antibióticos en algún momento de sus vidas por problemas médicos.Se realizaron extracciones de sangre de 40ml a cada paciente y se analizaron empleando un test ELISA, para identificar la posible presencia de un elemento contaminante indebido con propiedades de hapteno.4 de 15 sujetos (26%) mostraron una cantidad de oxitetraciclina en suero6 ng/g (considerado el límite de seguridad); 10 de 15 (66%) sujetos presentaron una cantidad de doxiciclina6 ng/g; y 3 de 15 (30%) sujetos presentaron un alto nivel sérico de ambas moléculas.Aunque no se llegó a obtener evidencia de una relación directa entre la acumulación de antibióticos corporales a largo plazo y una disfunción intestinal crónica y/o alergias a los alimentos, las trazas en sangre de estos compuestos en una población con alguna intolerancia a los alimentos pero por lo demás sana, podría considerarse el primer paso de una vía de sensibilización. Nuestros próximos objetivos prevén un estudio más profundo del desencadenante sensibilizador a partir de la exposición crónica a antibióticos en humanos por medio de la administración zootécnica de comida avícola.

Introduction: Antibiotics are largely employed in zootechnical feed to preserve human and animal species from zoonosis due pathogenic infective agents. Aim: Due to the increasing number of pathologies related to diet (e.g. food intolerances), we investigated the toxic effects induced by antibiotics residues, oxytetracyclines, present within the industrial food on both human and domestic animals' health. Zootechnical products obtained from animal bones industrial transformation, and their related toxic effects have been pointed out. Methods: Comparative analysis of published papers has been conducted from 1910 up to 2014. Results: The comparative analysis revealed the presence of oxytetracycline residues and other antibiotics in food intended for human and animal consumption, which resulted in multisystemic toxic effects. Discussion: Either metabolism and possible measures to prevent exposure to oxytetracycline have also been examined, however a more detailed understanding of biochemical effects of such class of antibiotics is required. Introducción: los antibióticos se emplean ampliamente en la alimentación zootécnica para proteger a las especies humana y animal de las zoonosis por agentes infecciosos patogénicos. Objetivo: dado el creciente número de enfermedades relacionadas con la dieta (p. ej., intolerancias alimentarias), investigamos los efectos tóxicos inducidos por los residuos antibióticos, oxitetraciclinas, presentes en los alimentos industriales tanto sobre la salud humana como animal. Se destacan los productos zootécnicos obtenidos de la transformación industrial de los huesos animales y sus efectos tóxicos relacionados. Métodos: análisis comparativo de las publicaciones realizadas desde 1910 hasta 2014. Resultados: el análisis comparativo reveló la presencia de residuos de oxitetraciclina y otros antibióticos en alimentos pensados para el consumo humano y animal, lo que produjo efectos tóxicos multisistémicos. Discusión: el metabolismo y las posibles medidas para evitar la exposición a la oxitetraciclina también se han examinado, sin embargo, se precisa de un conocimiento más detallado de los efectos bioquímicos de tal clase de antibióticos.
