The objective of study was to evaluate and correlate the pathological characteristics of breast cancer patients with estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (Her2/neu) detected by immunohistochemistry and/or fluorescent in situ hybridization method. We have conducted 2 year study of 204 cases of breast cancer at HCG-Medisurge Hospitals, Ahmedabad from 2009 to 2011. Significant correlation was found in ER and PR expression whereas no correlation was found in hormonal receptors and Her2/neu expression. ER and PR positivity increased with advancing age in breast carcinoma patients while not affecting Her2/neu expression. The expression of hormone receptors were higher in infiltrating lobular carcinoma and infiltrating duct carcinoma subtypes of breast carcinoma as compared to other subtypes such medullary and in situ carcinoma. High-grade carcinoma patients were predominantly ER/PR negative and Her2/neu positive as compared to lower grade breast carcinoma whereas high-stage carcinoma patients were ER/PR positive and Her2/neu positive as compared to lower stage breast carcinoma. 相似文献

Engineering education has been slow to adopt research-based educational innovations. Few prior works on such adoption have investigated the combined classroom experiences of instructors and students when such innovations are being implemented. Therefore, this work focuses on the lived experiences of an instructor and her students when adopting an active, blended, and collaborative learning environment, known as Freeform, in a second-year dynamics course. Weekly reflections from the instructor were processed alongside student interviews using Thematic Analysis to discern prominent themes in their perspectives for comparison and discussion. The results indicate that the instructor navigated internal tensions between her previous instructional preferences and the philosophy and resources of Freeform. Similarly, students had to adapt to this new philosophy and suite of resources that were uncommon for their institution. Ultimately, this work highlights the contextual natures of teaching and learning, and how situational factors can influence educational innovation. 相似文献

Effective teaching and learning in higher education is an important focal point of literature around the globe. Various models are presented as desirable and fostering optimal conditions for teaching and learning. However, each model must be examined within the context of its institutional culture, mission and strategic plan to ascertain if it meets the envisaged goals. The Reinventing Teaching Project survey conducted at Flinders University in 2009 provided a unique opportunity for academic staff and students across all faculties to respond to a survey that explored their perceptions of optimal learning conditions and assessed if the campus environment was conducive to effective teaching and learning practices. The exploratory study was designed to gather qualitative and quantitative data on the motivation of teachers and learners to engage with learning and learners (or not). The results of the survey present valuable insights into what teachers and learners consider to be important attributes of optimal teaching and learning and indicate a number of similarities and differences among teacher-student perceptions. This paper identifies and discusses some of the pertinent outcomes of the study to provide a framework for other similar studies. 相似文献

Global health is becoming an increasingly important component of medical education. Medical libraries have an opportunity to assist global health residents with their information needs, but first it is important to identify what those needs are and how best they can be addressed. This article reports a collaboration between global health faculty and an academic medical librarian to assess the information needs of global health pathway residents and how assessment data are used to create a multicomponent program designed to enhance global health education. 相似文献

Studies have reported an inverse association between language development and behavioral inhibition or shyness across childhood, but the direction of this association remains unclear. This study tested alternative hypotheses regarding this association in a large sample of toddlers. Data on behavioral inhibition and expressive and receptive language abilities were collected from 816 twins at ages 14, 20, and 24 months. Growth and regression models were fit to the data to assess the longitudinal associations between behavioral inhibition and language development from 14 to 24 months. Overall, there were significant associations between behavioral inhibition and expressive language, and minimal associations with receptive language, indicating that the association is better explained by reticence to respond rather than deficient language development. 相似文献

The driving force in the pursuit for quantum computation is the exciting possibility that quantum algorithms can be more efficient
than their classical analogues. Research on the subject has unraveled several aspects of how that can happen. Clever quantum
algorithms have been discovered in recent years, although not systematically, and the field remains under active investigation.
Richard Feynman was one of the pioneers who foresaw the power of quantum computers. In this issue dedicated to him, I give
an introduction to how particle and wave aspects contribute to the power of quantum computers. Shor’s and Grover’s algorithms
are analysed as examples. 相似文献
