Objectives: The evaluation of the learning environment has become critical to professional development and student success. This study aims to evaluate the viewpoints of nursing sciences students on the learning environment using the Dundee Ready Education Environment Measure (DREEM) at a Higher Institute of Nursing Sciences in Tunisia. Methods: A descriptive cross-sectional study was performed on 200 students at the Higher Institute of Nursing Sciences. The Dundee Ready Education Environment Measure was used as a worldwide tool. Descriptive statistics and one-way analysis of variance with a post hoc Tukey-Kramer multiple comparisons test were used for data analysis. Results: The total mean score on the 50-item DREEM inventory was 111.9 out of a maximum of 200. Students’ perceptions of learning, their teachers, their academic self, and of the atmosphere were more positive than negative. Student social self-perception was negatively evaluated. Students were not satisfied with the support system in the institute. The DREEM score was significantly higher for the students in the first year of study (P Conclusion: This is the first study in Tunisia assessing the nursing learning environment;it showed a positive assessment. Therefore, improvements are required, especially in the learning and social domains of the educational environment.

The programmed death 1 （PD-1） pathway is a way of inhibiting T-cell proliferation and cytokine production. This pathway is important for maintaining peripheral tolerance. Different mechanisms and cytokines are involved in this pathway. Herein, we show the contribution of endogenous TGF-β to increasing PD-1 expression after T cell receptor （TCR） activation.

In this paper wavelet functions are introduced in the context of q-theory. We precisely extend the case of Bessel and q-Bessel wavelets to the generalized q-Bessel wavelets. Starting from the （q,v）-extension （v = （α,β）） of the q-case, associated generalized q-wavelets and generalized q-wavelet transforms are developed for the new context. Reconstruction and Placherel type formulas are proved.
