Investigation of growth curves with different nonlinear models and MARS algorithm in broiler chickens.

This study was conducted to determine the live weight model of the broiler chicks by using the most appropriate mathematical growth curves. Live weights were used in broiler chicks grown for 0-6 weeks. Logistics, Gompertz, Weibull, Hossfeld and Von Bertalanffy models and multivariate adaptive regression splines (MARS) data mining algorithm were used to define the live weights of the chickens.

Evaluation of mucosal status in the follow-up of pediatric patients with celiac disease: the role of serology.

Unlabelled: Recent guidelines suggest non-biopsy serology-based approach for the diagnosis of celiac disease; however, there is no evidence-based data regarding noninvasive follow-up of mucosal healing. The aim of this study is to investigate the efficacy of serology in reflecting mucosal status in the follow-up of pediatric patients with celiac disease. This is a validation study conducted at a university hospital.

Electrode effects on the observability of destructive quantum interference in single-molecule junctions.

Destructive quantum interference (QI) has been a source of interest as a new paradigm for molecular electronics as the electronic conductance is widely dependent on the occurrence or absence of destructive QI effects. In order to interpret experimentally observed transmission features, it is necessary to understand the effects of all components of the junction on electron transport. We perform non-equilibrium Green's function calculations within the framework of density functional theory to assess the structure-function relationship of transport through pyrene molecular junctions with distinct QI properties.

Low Titer Tissue Transglutaminase Antibodies: A Link to Helicobacter pylori Infection?

Introduction: Low serum titer of anti-tissue transglutaminase (tTG) has been described in various conditions without any evidence of celiac disease (CD). Infectious agents have been suggested to trigger autoimmunity and promote the production of anti-tTG. The aim of this study was to investigate if there is a link between a positive celiac serology and concomitant Helicobacter pylori infection in children.

Gastrointestinal sarcoidosis presenting with malabsorption at an early age.

Sarcoidosis is a chronic multisystemic granulomatous disease that predominantly involves the thoracic lymph nodes and lungs and primarily occurs in young adults. Isolated extrapulmonary localization is uncommon in adults, and exceptionally rare in the pediatric age group. A 4-year-old male patient with chronic diarrhea and abdominal distention for the last 8 months is presented.
