Summary: Changes in taste have been perceived as a common side effect of different cancers and may lead to malnutrition. Hence, the importance of understanding cancer patients' sensory taste perceptions and its impact on nutritional status, quality of life (QoL), and oral nutrition supplements (ONS) compliance becomes crucial. This qualitative study involved semi-structured, in-depth interviews with 24 adults (15 with multiple myeloma and 9 with head & neck cancer). The interviews were transcribed and the data analysis was conducted using reflexive thematic analysis and template analysis. This guided the development of four themes: 1. Taste and smell changes, 2. Impact on nutritional status and quality of life, 3. Information and help available for people experiencing changes in their taste, and 4. ONS and its compliance. Our findings show significant negative impact of chemosensory changes on nutritional status, quality of life and ONS compliance. Patient's experience with the level of support received for the management of taste changes during cancer treatment varied widely. Providing adequate information and support in a timely manner about changes in taste during treatment can improve patients' coping strategies and maintain their nutritional status. Overall, the findings highlight the importance of addressing taste changes and ONS compliance for people with multiple myeloma and head and neck cancer undergoing treatment. Specifically, the taste changes and its impact experienced by people with head and neck cancer were found to be more severe than those experienced by multiple myeloma patients. This study provides an understanding of changes in sensory taste perception experienced by cancer patients and its impact on nutritional status and QoL. This understanding can provide insight into ways to improve ONS consumption and compliance for preventing malnutrition. It is crucial to further conduct ONS sensory evaluations that cater to the specific needs of this cohort to help prevent malnutrition among cancer patients.

This auto-ethnographic essay draws upon Foucault's Archaeology of Knowledge to discuss the condition of Indian women in the Humanities in academia today. While acknowledging the encouragingly gender-inclusive projections in India's National Education Policy vision statement from 2020, I argue for more probing engagement with the concrete reality of being a woman teacher and researcher in the increasingly competitive and corporatized milieu of higher education. My methodology has been a close reading of the NEP's vision statement to analyze recurrences of terms and concepts as pointers to its discursive field. I argue that this policy statement implicitly envisions an empowered new-age Indian woman teacher, notionally mother to all her pupils, aiding their awakening intuitively from the very heart of her experiences, skills, and memories. Against this somewhat idealized feminine ecology of the NEP in principle and spirit, I juxtapose the actual everyday choices and struggles of women in academic positions. Does the decolonization of education in spirit also impart actual transformative agency to women academics? Will women be listened to? Not one essential woman, but heterogeneous women--women across different strata, identities, professional spaces, and ideologies? Above all, my essay probes the challenges and dividends of transitioning to a more home-grown teaching and research methodology derived from current Western academic models. For instance, what forms and lines of interdisciplinarity could best serve the interest of quality control in research and teaching? In the third and last section, I argue that women are equal contributors in the discourse of academics in the future. We are committed stakeholders that can help enhance collective performance and efficiency in ways that are commensurate and compatible with our particular needs, contexts, restraints, aptitudes, and encumbrances. I conclude my essay by urging colleagues in academia, women and men, to recognize that we can truly deliver on this challenge only in a spirit of intellectual, ethical, and interpersonal collaboration and collegiality.

Early innate immune responses play an important role in determining the protective outcome of Mycobacterium tuberculosis (Mtb) infection. Nuclear factor κB (NF-κB) signaling in immune cells regulates the expression of key downstream effector molecules that mount early antimycobacterial responses. Using conditional knockout mice, we studied the effect of abrogation of NF-κB signaling in different myeloid cell types and its impact on Mtb infection. Our results show that the absence of IKK2-mediated signaling in all myeloid cells resulted in increased susceptibility to Mtb infection. In contrast, the absence of IKK2-mediated signaling in CD11c+ myeloid cells induced early proinflammatory cytokine responses, enhanced the recruitment of myeloid cells, and mediated early resistance to Mtb. Abrogation of IKK2 in MRP8-expressing neutrophils did not affect disease pathology or Mtb control. Thus, we describe an early immunoregulatory role for NF-κB signaling in CD11c-expressing phagocytes and a later protective role for NF-κB in LysM-expressing cells during Mtb infection.

The ADP ribosyltransferases (PARPs 1-17) regulate diverse cellular processes, including DNA damage repair. PARPs are classified on the basis of their ability to catalyze poly-ADP-ribosylation (PARylation) or mono-ADP-ribosylation (MARylation). Although PARP9 mRNA expression is significantly increased in progressive tuberculosis (TB) in humans, its participation in host immunity to TB is unknown. Here, we show that PARP9 mRNA encoding the MARylating PARP9 enzyme was upregulated during TB in humans and mice and provide evidence of a critical modulatory role for PARP9 in DNA damage, cyclic GMP-AMP synthase (cGAS) expression, and type I IFN production during TB. Thus, Parp9-deficient mice were susceptible to Mycobacterium tuberculosis infection and exhibited increased TB disease, cGAS and 2'3'-cyclic GMP-AMP (cGAMP) expression, and type I IFN production, along with upregulation of complement and coagulation pathways. Enhanced M. tuberculosis susceptibility is type I IFN dependent, as blockade of IFN a receptor (IFNAR) signaling reversed the enhanced susceptibility of [Parp9.sup.-/-] mice. Thus, in sharp contrast to PARP9 enhancement of type I IFN production in viral infections, this member of the MAR family plays a protective role by limiting type I IFN responses during TB., Introduction Mycobacterium tuberculosis infects approximately 25% of the world's population and causes tuberculosis (TB), a leading infectious disease that results in approximately 1.3 million deaths annually. Although a majority of [...]

Magnetometer measurements are one of the critical components necessary to improve our understanding of the intricate physical processes coupling mass, momentum, and energy within near-Earth space and throughout our solar system. However, these measurements are often contaminated by stray magnetic fields from the spacecraft hosting the magnetic field sensors, and the data often requires the application of interference mitigation algorithms prior to scientific use. Rigorous numerical validation of these techniques can be challenging when they are applied to in-situ spaceflight data, as a ground truth for the local magnetic field is often unavailable. This manuscript introduces and details the generation of an open-source dataset designed to facilitate the assessment of interference mitigation techniques for magnetic field data collected during spaceflight missions. The dataset contains over 100 hours of magnetic field data comprising mixtures of near-DC trends, physically-synthesized interference, and pseudo-geophysical phenomena. These constituent source signals have been independently captured by four synchronized magnetometers sampling at high cadence and combined into 30-minute intervals of data representative of events and interference seen in historic missions. The physical location of the four magnetometers relative to the interference sources enables researchers to test their interference mitigation algorithms with various magnetometer suite configurations, and the dataset also provides a ground truth for the underlying interference signals, enabling rigorous quantification of the results of past, present, and future interference mitigation efforts.
