Antibiotic susceptibility of the bacteria causing odontogenic infections
2006
Objetivos: Identificar la flora bacteriana y su susceptibilidad a varios antibióticos utilizados en infecciones odontogénicas de localización periapical y en las pericoronaritis del tercer molar inferior, para poder adaptar convenientemente el tratamiento antibiótico a las exigencias de tales infecciones, y evitar así los efectos secundarios y los sobretratamientos con antibióticos. Material y métodos: Se han seleccionado con unos criterios de inclusión y de exclusión a 64 pacientes que presentaban una infección odontogénica. Se recogieron muestras de las lesiones en condiciones de máxima asepsia, evitando la contaminación por flora saprófita bucal. Las muestras se sembraron en medios de cu…
Room-Temperature Magnetic Bistability in a Salt of Organic Radical Ions
2021
International audience; Cocrystallization of 7,7′,8,8′-tetracyanoquinodimethane radical anion (TCNQ −•) and 3-methylpyridinium-1,2,3,5dithiadiazolyl radical cation (3-MepyDTDA +•) afforded isostructural acetonitrile (MeCN) or propionitrile (EtCN) solvates containing cofacial π dimers of homologous components. Loss of lattice solvent from the diamagnetic solvates above 366 K affords a high-temperature paramagnetic phase containing discrete TCNQ −• and weakly bound π dimers of 3-MepyDTDA +• , as evidenced by X-ray diffraction methods and magnetic susceptibility measurements. Below 268 K, a first-order phase transition occurs, leading to a low-temperature diamagnetic phase with TCNQ −• σ dimer…
Evaluation of Superparamagnetic Silica Nanoparticles for Extraction of Triazines in Magnetic in-Tube Solid Phase Microextraction Coupled to Capillary…
2014
The use of magnetic nanomaterials for analytical applications has increased in the recent years. In particular, magnetic nanomaterials have shown great potential as adsorbent phase in several extraction procedures due to the significant advantages over the conventional methods. In the present work, the influence of magnetic forces over the extraction efficiency of triazines using superparamagnetic silica nanoparticles (NPs) in magnetic in tube solid phase microextraction (Magnetic-IT-SPME) coupled to CapLC has been evaluated. Atrazine, terbutylazine and simazine has been selected as target analytes. The superparamagnetic silica nanomaterial (SiO2-Fe3O4) deposited onto the surface of a capil…
Role of the gastroenterologist in the management of the obese patient.
2017
Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.
Bndocrinopathic Constitutions and Pathology of War*
1919
The clinical study of the internal secretions opens a vast field of research, so far little known, notwithstanding its great value in practical medicine. Particularly important are those states of hormonic imbalance which are at the border line between health and disease, and which represent either latent or mild endocrinopathic conditions, real endocrine diatheses or endocrinopathic temperaments. It is already understood that for each of the best known endocrine glands, in addition to frank malfunctions there must be recognized minor degrees of perturbation giving rise to the endocrinopathic habitus. To the French writers, especially Levi and Rotschild, we owe much of our knowledge of the …

Longitudinal Study on Growth and Body Mass Index before and after Diagnosis of Childhood Craniopharyngioma
2004
Abstract We analyzed whether childhood craniopharyngioma predisposes to obesity and growth impairment. Height/length, body mass index (BMI), and hypothalamic involvement were evaluated in 90 patients at standardized ages and time points before, after, and at the time of diagnosis. Relevant decreases in height sd score (SDS) started at 10–12 months of age and persisted until diagnosis of childhood craniopharyngioma. Relevant increases in BMI SDS were detectable between 4 and 5 yr of age. Postoperative BMI SDS (yr 1–6) had a weak positive correlation with BMI SDS at the time of diagnosis. In linear regression analysis, hypothalamic tumor involvement (P < 0.001), ponderal index at birth…
Distribution of Ha-ras alleles in patients with colorectal cancer and Crohn's disease.
1991
The allele distribution of the Ha-ras gene on chromosome 11p was analysed by the restriction fragment length polymorphism of the enzymes Mspl/Hpall in 238 individuals. The investigation covered 116 patients with colorectal carcinoma and 122 patients with Crohn's disease, representing two patient populations with the same ethnic origin, one with a malignant and the other a benign disease of the same organ system. A total of 17 different alleles were detected belonging to the common, intermediate, and rare classes according to the original nomenclature of Ha-ras alleles. Patients with Crohn's disease showed no difference in the distribution of Ha-ras alleles when compared with expected freque…
The Potential Use of Resveratrol for Cancer Prevention.
2019
In addition to the traditional treatments of cancer and cancer prevention, the use of natural compounds, especially those found in food, should be considered. To clarify if resveratrol has the potential for cancer prevention and the possibility of use in therapy, the following must be taken into account: data from epidemiology, clinical protocol (case and control), preclinical studies (lab animals), use of established cell lines as models of cancer cells, test tube assays (enzymes activities), and requirements of nanotechnologies in order to discover new drugs to fight cancer. From this perspective and future expected advances, more information is needed such as improved efficacy, methods o…
