Published: November 2019

Abstract
Differential calculus becomes a primary pre-requisite material for every student to start learning calculus. It mainly discusses the concepts and theorems regarding derivative of functions. Many mathematics educators believe that learning differential calculus needs specific conditions and attitude as it cannot be set as rote and procedural learning. This research aims to find out the students’ perception towards the implementation of self-regulated flipped classroom approach in their differential calculus class. Thirty-six students participated in the seven meetings of the class and gave their perceptions at the end of every meeting. They were engaged in a various type of learning activities outside the classroom such as setting their own goal, gaining information from many sources, and uploading a video of their presentation, while during the class, they were assessed with an interview confirming their understanding about the topics. The result suggests that the self-regulated flipped classroom approach is promising to maintain the students’ right attitude towards differential calculus.

Published: November 2019

Abstract

Objectives
The implementation of next-generation sequencing (NGS) in routine clinical hematology practice remains limited. We evaluate the clinical value of NGS in the screening, diagnosis, and follow-up in hematologic neoplasms.

Methods
A targeted NGS panel was used to assess a total of 178 patients for questionable or previously diagnosed myeloid neoplasms.

Results
Gene variants were identified in 53% of patients. Novel variants were identified in 29% of patients and variants of unknown significance in 34%. Bone marrow samples yielded a higher number of variants than in peripheral blood. NGS is a more sensitive test than conventional cytogenetics. In several cases, NGS played a key role in the screening, diagnostics, prognostic stratification, and the clinical follow-up of a wide variety of myeloid neoplasms.

Conclusions
NGS is an effective tool in the evaluation of suspected and confirmed hematologic neoplasms and could become part of the routine workup of patients.
