Disparities in funding for Nobel Prize awards in medicine and physiology across nationalities, races, and gender.

Since 1901, the Nobel Prize in Physiology and Medicine has been awarded to numerous individuals for their outstanding contributions. This article presents a comprehensive analysis of the Nobel Prize recipients, focusing on gender, race, and nationality. We observe that an alarming disparity emerges when we examine the underrepresentation of Black scientists among Nobel laureates. Furthermore, trends in nationalities show how Americans make up the majority of Nobel Prize winners, while there is a noticeable lack of gender and racial minority winners of the Nobel Prize in Physiology and Medicine. Together, this highlights the importance of diversity and inclusion in scientific achievement. We offer suggestions and techniques, including funding opportunities and expanding nominators, to improve the gender, racial, and geographical diversity of Nobel Prizes.

A pilot study on our non-traditional, varied writing accountability group for historically excluded and underrepresented persons in STEMM.

Underrepresented faculty have higher burnout rates and lower grant attainment rates when compared with their non-minority counterparts. Many in science, technology, engineering, mathematics, and medicine (STEMM) disciplines, including underrepresented individuals, often have difficulty dedicating time to the writing process, with trainees often being relegated to laboratory tasks in their training years, resulting in a lack of practice in academic writing. Notably, past studies have shown that grant attainment rates of underrepresented individuals are lower than their majority counterparts. Here, we sought to consider a mechanism targeted to underrepresented individuals, although applicable to everyone, to help overcome traditional barriers to writing in STEMM. The authors have hosted a writing accountability group (WAG) that uniquely provides a format focused on physical activity and different forms of writing to strengthen both career development and award/funding attainment. Our objectives were to evaluate this unique format, thus creating a resource for individuals and institutions to learn about WAGs and expand upon the framework to formulate their own WAG. To do this, we performed a small pilot study (n = 21) to investigate attitudes towards the WAG. We present the results of a survey conducted among underrepresented WAG participants, which spanned different career stages and was highly diverse demographically. Our results show that following attendance of our WAG, individuals did not note a significant change in scales pertaining to John Henryism (high-effort coping), resilience, sense of belonging, or grit. However, significant increases were noted in the self-perceived ability to handle stress, confidence in applying for awards, appreciation for mentoring, and satisfaction of WAGs. Taken together, the results of this study suggest that our unique WAG format can have some positive results as a career and writing development opportunity and may be able to support underrepresented individuals in attaining funding at higher education institutions.

Diversity, Equity and Inclusion in the Laboratory: Strategies to Enhance Inclusive Laboratory Culture.

Building a diverse laboratory that is equitable is critical for the retention of talent and the growth of trainees professionally and personally. Here, we outline several strategies including enhancing understanding of cultural competency and humility, establishing laboratory values, and developing equitable laboratory structures to create an inclusive laboratory environment to enable trainees to achieve their highest success.

Project Strengthen: An STEMM-focused career development workshop to prepare underrepresented minority students for graduate school.

Maximizing Access to Research Careers (MARC) programs are aimed to increase diversity in science, technology, engineering, math, and medicine (STEMM) fields. However, limited programs and eligibility requirements limit the students who may apply to similar programs. At Winston-Salem State University, we piloted a series of workshops, collectively termed Project Strengthen, to emulate some of the key aspects of MARC programs. Following the workshop, Project Strengthen students showed a significant increase in their understanding of essential educational development skills, such as writing personal statements, applying to graduate school, studying for the GRE, and seeking summer internships. This suggests Project Strengthen may be a potential lower cost comparable option than MARC to make up for current deficiencies in preparedness for graduate school. We also provide educational materials from Project Strengthen, including a clear framework for this seminar series, six ready-made PowerPoints to share with trainees that have been demonstrated to be effective.

Three-dimensional mitochondria reconstructions of murine cardiac muscle changes in size across aging.

With sparse treatment options, cardiac disease remains a significant cause of death among humans. As a person ages, mitochondria breakdown and the heart becomes less efficient. Heart failure is linked to many mitochondria-associated processes, including endoplasmic reticulum stress, mitochondrial bioenergetics, insulin signaling, autophagy, and oxidative stress. The roles of key mitochondrial complexes that dictate the ultrastructure, such as the mitochondrial contact site and cristae organizing system (MICOS), in aging cardiac muscle are poorly understood. To better understand the cause of age-related alteration in mitochondrial structure in cardiac muscle, we used transmission electron microscopy (TEM) and serial block facing-scanning electron microscopy (SBF-SEM) to quantitatively analyze the three-dimensional (3-D) networks in cardiac muscle samples of male mice at aging intervals of 3 mo, 1 yr, and 2 yr. Here, we present the loss of cristae morphology, the inner folds of the mitochondria, across age. In conjunction with this, the three-dimensional (3-D) volume of mitochondria decreased. These findings mimicked observed phenotypes in murine cardiac fibroblasts with CRISPR/Cas9 knockout of Mitofilin, Chchd3, Chchd6 (some members of the MICOS complex), and Opa1, which showed poorer oxidative consumption rate and mitochondria with decreased mitochondrial length and volume. In combination, these data show the need to explore if loss of the MICOS complex in the heart may be involved in age-associated mitochondrial and cristae structural changes.NEW & NOTEWORTHY This article shows how mitochondria in murine cardiac changes, importantly elucidating age-related changes. It also is the first to show that the MICOS complex may play a role in outer membrane mitochondrial structure.

Asian Americans in STEM are not a monolith.

Despite tremendous diversity, Asian Americans in STEM are grouped and viewed as a homogeneous monolith, facing stereotypes and disparities. We propose solutions that include disaggregating the Asian American grouping and recognizing the diverse individual ethnic subgroups that comprise Americans of Asian ancestry to implement change within the STEM field.

Using quotients as a mentor to facilitate the success of underrepresented students.

Choosing a mentor requires a certain level of introspection for both the mentor and the mentee. The dynamics of mentorship may change depending on the academic status of the mentee. Regardless, mentors should help their trainees grow both academically and professionally. The success of an individual in the fields of science, technology, engineering, mathematics, and medicine (STEMM) depends on more than intellectual capacity; a holistic view encompassing all factors that contribute to scientific achievement is all-important. Specifically, one new method scientists can adopt is quotients, which are scales and techniques that can be used to measure aptitude in a specific area. In this paper, we focus on these factors and how to grow one's adversity quotient (AQ), social quotient (SQ), and personal growth initiative scale (PGIS). We also look at how mentors can better understand the biases of their trainees. In addressing this, mentors can help trainees become more visible and encourage other trainees to become allies through reducing biases.

Cardiovascular hemodynamics in mice with tumor necrosis factor receptor-associated factor 2 mediated cytoprotection in the heart.

Introduction: Many studies in mice have demonstrated that cardiac-specific innate immune signaling pathways can be reprogrammed to modulate inflammation in response to myocardial injury and improve outcomes. While the echocardiography standard parameters of left ventricular (LV) ejection fraction, fractional shortening, end-diastolic diameter, and others are used to assess cardiac function, their dependency on loading conditions somewhat limits their utility in completely reflecting the contractile function and global cardiovascular efficiency of the heart. A true measure of global cardiovascular efficiency should include the interaction between the ventricle and the aorta (ventricular-vascular coupling, VVC) as well as measures of aortic impedance and pulse wave velocity. Methods: We measured cardiac Doppler velocities, blood pressures, along with VVC, aortic impedance, and pulse wave velocity to evaluate global cardiac function in a mouse model of cardiac-restricted low levels of TRAF2 overexpression that conferred cytoprotection in the heart. Results: While previous studies reported that response to myocardial infarction and reperfusion was improved in the TRAF2 overexpressed mice, we found that TRAF2 mice had significantly lower cardiac systolic velocities and accelerations, diastolic atrial velocity, aortic pressures, rate-pressure product, LV contractility and relaxation, and stroke work when compared to littermate control mice. Also, we found significantly longer aortic ejection time, isovolumic contraction and relaxation times, and significantly higher mitral early/atrial ratio, myocardial performance index, and ventricular vascular coupling in the TRAF2 overexpression mice compared to their littermate controls. We found no significant differences in the aortic impedance and pulse wave velocity. Discussion: While the reported tolerance to ischemic insults in TRAF2 overexpression mice may suggest enhanced cardiac reserve, our results indicate diminished cardiac function in these mice.

Systematic Transmission Electron Microscopy-Based Identification and 3D Reconstruction of Cellular Degradation Machinery.

Various intracellular degradation organelles, including autophagosomes, lysosomes, and endosomes, work in tandem to perform autophagy, which is crucial for cellular homeostasis. Altered autophagy contributes to the pathophysiology of various diseases, including cancers and metabolic diseases. This paper aims to describe an approach to reproducibly identify and distinguish subcellular structures involved in macroautophagy. Methods are provided that help avoid common pitfalls. How to distinguish between lysosomes, lipid droplets, autolysosomes, autophagosomes, and inclusion bodies are also discussed. These methods use transmission electron microscopy (TEM), which is able to generate nanometer-scale micrographs of cellular degradation components in a fixed sample. Serial block face-scanning electron microscopy is also used to visualize the 3D morphology of degradation machinery using the Amira software. In addition to TEM and 3D reconstruction, other imaging techniques are discussed, such as immunofluorescence and immunogold labeling, which can be used to classify cellular organelles, reliably and accurately. Results show how these methods may be used to accurately quantify cellular degradation machinery under various conditions, such as treatment with the endoplasmic reticulum stressor thapsigargin or ablation of the dynamin-related protein 1.

Strategies for change: thriving as an individual with a disabilty in STEMM.

Disability remains an underacknowledged and underdiscussed topic in science, technology, engineering, mathematics, and medicine (STEMM). Social stigma and fear of negative outcomes have resulted in a consistent lack of disclosure. Disabilities cause social and professional difficulties for those that have them. While some faculty can be allies, past literature shows that steps must be taken to make disabilities visible in STEMM at both student and faculty levels. Here, we offer suggestions to better support faculty and students in enhancing the outcomes of individuals who have invisible disabilities. Critically, techniques such as abolishing stigma, universal learning, and better mentoring may improve the challenges faced by those who self-identify as an individual with a disability.
