Thematic Review Series: Nutrient Control of Metabolism and Cell Signaling Brain Responses to High-Protein Diets

Proteins are suspected to have a greater satiating effect than the other 2 macronutrients. After protein consumption, peptide hormones released from the gastrointestinal tract (mainly anorexigenic gut peptides such as cholecystokinin, glucagon peptide 1, and peptide YY) communicate information about the energy status to the brain. These hormones and vagal afferents control food intake by acting...

Giant Cell Tumor of the Sacrum: Series of 19 Patients and Review of the Literature

There are still some debates regarding the best treatment of Giant Cell Tumor (GCT) of the sacrum. Since GCT of this location is rare, therapeutic strategies are mainly based on the treatment of GCT in other anatomic locations. The objective of this study was to evaluate the oncologic and clinical results of surgical management of sacral GCT with and without local adjuvant therapy. Medical reco...

Recent Advances in T Cell Signaling in Aging

The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...

Pulmonary Langerhans Cell Histiocytosis: Case Series and Literature Review

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare disease with insidious onset and nonspecific manifestations. The objective of this article was to characterize the clinical manifestations and features of PLCH by retrospectively analyzing clinical data of patients with PLCH in addition to simultaneous review of literature.A retrospective analysis was conducted on clinical data of patient...
