LEARNING OBJECTS AND INTERACTIVE WHITEBOARDS: A EVALUATION PROPOSAL OF LEARNING OBJECTS FOR MATHEMATICS TEACHING

Learning objects and interactive whiteboards: a evaluation proposal of learning objects for mathematics teaching

The current conditions of the classroom learning tend to be a one-way process based in teacher exposition, this make a negative impact on learning make it a mechanical and not meaningful activity.One possibility to improve the quality of teaching is to innovate methodologies and varying forms of presenting information to students, Bottle Openers su

Serum neopterin concentrations and tryptophan degradation pattern in patients with late stage larynx carcinoma

As the disease-free 5-year-survival of late stage laryngeal carcinoma patients is extremely low, indoleamine-2,3-dioxygenase-1 (IDO)-induced tryptophan degradation may represent an immune escape mechanism which plays an important role in cancer spreading in advanced stage laryngeal cancers.We examined whether the late stage laryngeal cancer enhance

Protracted Clonal Trajectory of a JAK2 V617F-Positive Myeloproliferative Neoplasm Developing during Long-Term Remission from Acute Myeloid Leukemia

Although transformation of the myeloproliferative neoplasms (MPNs) to acute myeloid leukemia (AML) is well documented, development of an MPN in patients previously treated for, and in remission from, AML is exceedingly rare.A case is described in which a patient was successfully treated for AML and in whom a JAK2 V617F-positive MPN was diagnosed af

Placental growth factor promotes neural invasion and predicts disease prognosis in resectable pancreatic cancer

Abstract Background Surgery represents the only curative treatment option for pancreatic ductal adenocarcinoma (PDAC), but recurrence in more than 85% of patients limits the success of curative-intent tumor resection.Neural invasion (NI), particularly the spread of tumor cells along nerves into extratumoral regions of the pancreas, constitutes a we
