Anaemia is a frequent consequence of many gastrointestinal (GI) diseases in children and it can even be the initial presenting symptom of underlying chronic GI disease. The definition of anaemia is age and gender-dependent and it can be classified based on pathophysiology, red cell morphology, and clinical presentation. Although nutritional deficiencies, including GI malabsorption of nutrients and GI bleeding, play a major role, other pathophysiologic mechanisms seen in chronic GI diseases, whether inflammatory (e.

Background: Surveys based on capillary blood show that anaemia is rampant in India, but capillary blood haemoglobin (Hb) may not accurately reflect venous blood Hb concentrations. Further, iron deficiency (ID) is thought to be the main cause of anaemia, there are no venous blood-based surveys to confirm this.
Methods: A community-based (urban, slum and rural) cross-sectional, venous blood survey was conducted in eight Indian states to estimate anaemia and ID prevalences from Hb and inflammation-corrected plasma ferritin concentrations in adolescents, adults, and elderly.
π-π stacking interactions in tryptophan-lumiflavin-tyrosine: a structural model for riboflavin insertion into riboflavin-binding protein.

Context: Riboflavin (RF), also known as B2 vitamin, is the precursor to flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), two co-enzymes involved in many electron transport processes. Interactions of the isoalloxazine ring, common to all three compounds, are of great interest due to their biological function in flavoproteins and relevance in the transport by the carrier protein leading to development of drug delivery strategies and non-invasive diagnostics techniques. Based on protein crystallographic data, a computational investigation of the interactions in the complexes between lumiflavin, a model compound, and aromatic amino acids, tyrosine and tryptophan, was pursued with the goal of characterizing noncovalent interactions.

: A large amount of recent evidence suggests that cellular inability to consume oxygen could play a notable part in promoting sepsis as a consequence of mitochondrial dysfunction and oxidative stress. The latter could, in fact, represent a fundamental stage in the evolution of the "natural history" of sepsis. Following a study previously conducted by the same working group on heart samples, the present research project aims to evaluate, through an immunohistochemical study, the existence and/or extent of oxidative stress in the brains of subjects who died due to sepsis and define, after reviewing the literature, its contribution to the septic process to support the use of medications aimed at correcting redox anomalies in the management of septic patients.
