Diversity of Protists III01:27

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...
Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
Diversity in Cell Signaling Responses01:22

Diversity in Cell Signaling Responses

The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity. 
Graded and Abrupt Responses
Some signaling systems generate...

Diversity of Protists II

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Forced Transdifferentiation01:28

Forced Transdifferentiation

Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.
Artificial transdifferentiation occurs...
Diversity of Protists IV01:27

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

  • Academic Medicine
  • Healthcare Management
  • Diversity and Inclusion Studies

Background:

  • The US healthcare system faces significant challenges from reform, demographic shifts, economic issues, and physician shortages.
  • Academic medical institutions are critical to navigating these complex healthcare challenges.
  • Existing diversity frameworks can be adapted to the academic medicine context.

Purpose of the Study:

  • To propose the adaptation of IBM's diversity framework for academic medicine.
  • To outline the evolution of diversity and inclusion thinking within academic medicine.
  • To highlight the role of diversity and inclusion as integral to institutional excellence.

Main Methods:

  • Analysis of diversity evolution in academic medicine through three distinct phases.
  • Application of a diversity framework, originally implemented by IBM, to the academic medicine setting.
  • Examination of the shift from isolated diversity efforts to integrated diversity and inclusion strategies.

Main Results:

  • Phase 1: Isolated efforts to remove barriers, with diversity and excellence as competing goals.
  • Phase 2: Diversity awareness increased, with diversity and excellence as parallel goals.
  • Phase 3 (Emerging): Integration of diversity and inclusion into core institutional functions for achieving excellence.

Conclusions:

  • Diversity and inclusion are increasingly recognized as essential for academic medicine's success.
  • The Association of American Medical Colleges will support medical schools in integrating diversity as a core strategy.
  • Moving diversity from a peripheral to a core strategy is vital for academic medical institutions to meet future healthcare demands.
